How to create a JavaScript object dynamically whose value is a function

I need a method that creates a Quasar Table column definition dynamically. The method below works, however, I believe that using a for loop in place of the long switch statement is a better solution.

How do I write a for loop that produces the same result as the following:

const createTableColumns = (numberOfColumns: number) => {
  const tableCols: QTableProps["columns"] = [];
  const numberOfColumnsStr = numberOfColumns.toString();

  switch (numberOfColumnsStr) {
    case "15":
      tableCols.push({
        name: "15",
        align: "center",
        label: "15",
        field: (row) => row.fifteen.value,
        format: (val, row) =>
          row.fifteen.isSlected ? `** ${val} **` : `${val}`,
        sortable: false,
      });
    case "14":
      tableCols.push({
        name: "14",
        align: "center",
        label: "14",
        field: (row) => row.fourteen.value,
        format: (val, row) =>
          row.fourteen.isSlected ? `** ${val} **` : `${val}`,
        sortable: false,
      });
    case "13":
      tableCols.push({
        name: "13",
        align: "center",
        label: "13",
        field: (row) => row.thirteen.value,
        format: (val, row) =>
          row.thirteen.isSlected ? `** ${val} **` : `${val}`,
        sortable: false,
      });
    case "12":
      tableCols.push({
        name: "12",
        align: "center",
        label: "12",
        field: (row) => row.twelve.value,
        format: (val, row) =>
          row.twelve.isSlected ? `** ${val} **` : `${val}`,
        sortable: false,
      });
    case "11":
      tableCols.push({
        name: "11",
        align: "center",
        label: "11",
        field: (row) => row.eleven.value,
        format: (val, row) =>
          row.eleven.isSlected ? `** ${val} **` : `${val}`,
        sortable: false,
      });
    case "10":
      tableCols.push({
        name: "10",
        align: "center",
        label: "10",
        field: (row) => row.ten.value,
        format: (val, row) => (row.ten.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });
    case "9":
      tableCols.push({
        name: "9",
        align: "center",
        label: "9",
        field: (row) => row.nine.value,
        format: (val, row) => (row.nine.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });
    case "8":
      tableCols.push({
        name: "8",
        align: "center",
        label: "8",
        field: (row) => row.eight.value,
        format: (val, row) => (row.eight.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });
    case "7":
      tableCols.push({
        name: "7",
        align: "center",
        label: "7",
        field: (row) => row.seven.value,
        format: (val, row) => (row.seven.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });
    case "6":
      tableCols.push({
        name: "6",
        align: "center",
        label: "6",
        field: (row) => row.six.value,
        format: (val, row) => (row.six.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });
    case "5":
      tableCols.push({
        name: "5",
        align: "center",
        label: "5",
        field: (row) => row.five.value,
        format: (val, row) => (row.five.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });
    case "4":
      tableCols.push({
        name: "4",
        align: "center",
        label: "4",
        field: (row) => row.four.value,
        format: (val, row) => (row.four.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });
    case "3":
      tableCols.push({
        name: "3",
        align: "center",
        label: "3",
        field: (row) => row.three.value,
        format: (val, row) => (row.three.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });

    case "2":
      tableCols.push({
        name: "2",
        align: "center",
        label: "2",
        field: (row) => row.two.value,
        format: (val, row) => (row.two.isSlected ? `** ${val} **` : `${val}`),
        sortable: false,
      });

    case "1":
      tableCols.push({
        name: "1",
        align: "center",
        label: "1",
        field: (row) => row.name,
        format: (val, row) => `${val}`,
        sortable: false,
      });

      break;
    default:
      console.error(`Game: createTableColumns DEFAULT!!!`);
  }

  tableCols.sort((a, b) => parseInt(a.name) - parseInt(b.name));
  return tableCols;
};

I’ve tried this:

const tableCols2: QTableProps["columns"] = [];
for (let colIndex = 0; colIndex < numberOfColumns; colIndex++) {
  const rowKeyArray = [
    "NotUsed",
    "one",
    "two",
    "three",
    "four",
    "five",
    "six",
    "seven",
    "eight",
    "nine",
    "ten",
    "eleven",
    "twelve",
    "thirteen",
    "fourteen",
    "fifteen",
  ];
  const colNumber: number = colIndex + 1;
  const rowKey: string = rowKeyArray[colIndex];
  const myObj = {
    name: colNumber.toString(),
    align: "center",
    label: colNumber.toString(),
    field: (row) => row[rowKey].value,
    format: (val, row) => (row[rowKey].isSlected ? `** ${val} **` : `${val}`),
    sortable: false,
  };

  tableCols2.push(myObj);
}

The curtain fails to rise when the ‘X’ button is clicked

I was told this:

In your showContainer function, you are trying to add the slide class
to the container element when the animation of the spinner ends.
However, the slide class is supposed to transition the container
upwards, but it seems it’s not being applied correctly.

It should work the same way as:

How this one works:

window.onload = function() {
  const container = document.querySelector(".video-containerA");
  const spinner = document.querySelector(".spinner");
  const exitButton = document.querySelector(".exitA");

  spinner.addEventListener("animationend", function() {
    container.classList.add("slide");
  });

  container.addEventListener("transitionend", function() {
    exitButton.classList.add("visible");
  });
};

After clicking the exit button the curtain should go up.

After it is up, exit button should be visible

**How do I fix this?

I am confused here.

The curtain is not going up.

I don’t understand, it should be working.

Is there a way to create vertical fixed sections like this in CSS/JS? [closed]

I’m trying to create a similar layout where each section shows up with scroll. Is there a way to create this with CSS/JS?

https://www.youtube.com/watch?v=LF7K2zuh-H8

I tried using position fixed and sticky for sections to make this work, but it doesn’t seem to be working.

A wavelike design appears to be flowing across the canvas from left to right. At its heart lies another small cloud, indicating some kind of technological feature or product.

.scroll_container {
  margin-top: 2800px;
  height: 1200px;
  margin-left: 20%;
  position: relative;
  overflow: hidden;
}

.scroll_container div {
  position: sticky;
  position: -webkit-sticky;
  width: 800px;
  height: 400px;
}

.scroll_1 {
  background: orange;
  top: 0px;
}

.scroll_2 {
  top: 400px;
  background: turquoise;
  z-index: 10;
}

.scroll_3 {
  top: 800px;
  background: teal;
  z-index: 20;
}
<div class="scroll_container">

Vitest giving syntaxerror

I am using vitest to run my ReactComponent tests.

import { render, screen } from '@testing-library/react';
import { Calc } from '../features/explore/Calc';

describe('calc tests', () => {


   it('should render calculator screen', () => {
     const { getByTestId } = render(<Calc />);

     expect(getByTestId('calc-title').textContent).toBe('Calculator');
   });

});

This is the vite.config.ts

import * as path from 'node:path';
import { defineConfig } from 'vitest/config';
import tsconfigPaths from 'vite-tsconfig-paths';

export default defineConfig({
   plugins: [tsconfigPaths()],

   test: {
      globals: true,
      environment: 'jsdom',
      setupFiles: [
        require.resolve('dotenv-mono/load'),
        path.resolve(__dirname, '__tests__/setupTests.ts'),
      ],
   include: ['**/*.test.{ts,tsx}'],},
});

How to resolve this issue ?

it gives error as :
FAIL tests/ExplorePage.test.tsx [ tests/ExplorePage.test.tsx ]
app:test:unit: SyntaxError: Named export ‘ScrollView’ not found. The requested module ‘react-native’ is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from ‘react-native’;
const { ScrollView: ScrollViewNative } = pkg;

I am not using ScrollView in my component directly.

How to make XAxis less crowded and not display all dates on spline chart using highcharts

I have a spline chart that is generated with Highcharts. How to make the x-axis less crowded? This is a month’s worth of data. Sometimes the data can be more than that. On the x-axis, sow only few dates rather than all of them.

PDF does not display on mobile device within a modal

On PC it works correctly, but when I try it on mobile I only get a button with the text “Open” but when I press it nothing happens.

I’ve already tried it in several browsers and they all give the same result.

This is the function I use:

async function frmMostrar(idPDF){
    $(cargador__).attr('style', 'display: flex;');
    await fetch(`/obtenerInformeFinalDrive`, {
        method: 'POST',
        body: JSON.stringify({ idPDF: idPDF }),
        headers: { "Content-Type": "application/json", "X-CSRF-TOKEN": xcsrftoken_ },
    })
    .then(response => {
        if (!response.ok) {
            throw new Error('No se pudo recuperar el PDF');
        }
        return response.blob();
    })
    .then(responseBlob => {
        const reader = new FileReader();
        reader.onload = () => {
            const byteArray = new Uint8Array(reader.result);
            const pdfBlob = new Blob([byteArray], { type: 'application/pdf' });
            const pdfUrl = URL.createObjectURL(pdfBlob);

            const iframe = document.createElement('iframe');
            iframe.src = pdfUrl;
            iframe.height = '100%';
            iframe.width = '100%';

            if (!alertify.modal_informe_final) {
                alertify.dialog("modal_informe_final", function() {
                    return {
                        main: function(message) {
                            this.message = message;
                        },
                        prepare: function() {
                            this.setContent(this.message);
                        }
                    };
                });
            }
            const modal = alertify.modal_informe_final(iframe).set({ onclosing:function(){}}).set({title: 'Informe final'}).maximize();
            const modalContainer = modal.elements.modal;
            modalContainer.classList.add('modal_informe_final');
        };
        reader.readAsArrayBuffer(responseBlob);
    })
    .catch(error => {
        console.error('Error al recuperar PDF:', error);
    });
    $(cargador__).attr('style', 'display: none;');
}

Problems with flask and javascript

the idea is when you click in the button of an actuador , it will send a message to the microcontroller to activate or deactivate a switch. The thing is that when I click on the actuador to send the MQTT message the following error appears:

Enviando comando al actuador 3: 1
1:954 Body being sent: {"mensaje":"1"}
1:955 1
1:956 
        
        
       POST http://127.0.0.1:5001/enviar_comando_actuador/3 400 (BAD REQUEST)
toggleSwitch @ 1:956
onclick @ 1:370
1:963 Response status: 400
1:979 Error al enviar comando al actuador: Error: HTTP status 400
    at 1:965:19

I have this html code:

{% for actuador in actuadores %}
  <div class="elemento">
    {% if actuador.tipo == 'switch' %}
    <button class="switch-button" id="switch_{{ actuador.id }}" 
    data-actuador-id="{{ actuador.id }}" 
    data-state="{{ actuador.estado_actual }}" 
    onclick="toggleSwitch(this)"
    style="background-color: {{ 'green' if actuador.estado_actual == '1' else 'red' }}">
        <span>{{ actuador.nombre }}</span><br>
        <span>{{ actuador.tipo }}</span><br>
        <span>{{ actuador.ubicacion }}</span>
    </button>

    
    
    {% elif actuador.tipo == 'altavoz' %}
    <button class="switch-button" id="switch_{{ actuador.id }}" data-actuador-id="{{ actuador.id }}" data-state="" onclick="">
        <span>{{ actuador.nombre }}</span><br>
        <span>{{ actuador.tipo }}</span><br>
        <span>{{ actuador.ubicacion }}</span>
    </button>
    
    {% endif %}
    <div class="menu-button" onclick="showMenu({{ actuador.id }})">...</div>
  </div>
{% else %}
  <p>No hay actuadores agregados. Por favor, agregue uno.</p>
{% endfor %}

The Javascript:

function toggleSwitch(buttonElement) {
    const actuadorId = buttonElement.dataset.actuadorId;
    let currentState = buttonElement.dataset.state;
    const newState = currentState === '1' ? '0' : '1';

    console.log(`Enviando comando al actuador ${actuadorId}: ${newState}`);
    console.log(`Body being sent:`, JSON.stringify({ mensaje: newState }));
    console.log(newState)
    fetch(`/enviar_comando_actuador/${actuadorId}`, {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ mensaje: newState })
        
    })
    .then(response => {
        console.log('Response status:', response.status);
        if (!response.ok) {
            throw new Error(`HTTP status ${response.status}`);
        }
        return response.json();
    })
    .then(data => {
        console.log('Respuesta del servidor:', data);
        if (data.success) {
            buttonElement.dataset.state = newState;
            buttonElement.style.backgroundColor = newState === '1' ? 'green' : 'red';
        } else {
            console.error('Error al procesar el comando:', data.message);
        }
    })
    .catch(error => {
        console.error('Error al enviar comando al actuador:', error);
    });
}

This is the flask route:

@main.route('/enviar_comando_actuador/<int:actuador_id>', methods=['POST'])
@login_required
def enviar_comando_actuador(actuador_id):
    if not request.is_json:
        print("Error: No JSON received")
        return jsonify({'success': False, 'message': 'Expected JSON content'}), 400

    data = request.get_json()
    comando = data.get('mensaje')
    print(f"Received JSON: {data}")  # Imprimir los datos JSON recibidos
    print(f"Received command for actuator {actuador_id}: {comando}")

    if comando not in ['0', '1']:
        print("Error: Invalid command value")
        return jsonify({'success': False, 'message': 'Invalid command value'}), 400

    try:
        actuador = Actuador.query.get(actuador_id)  # Use get() instead of get_or_404()
        if not actuador:
            print(f"Actuator with ID {actuador_id} not found")
            return jsonify({'success': False, 'message': 'Actuator not found'}), 404  # Return 404 for missing actuator
        print(f"Command {comando} will be sent to actuator {actuador_id}")
        # Simular el envío de comando al hardware aquí si es necesario
        return jsonify({'success': True, 'message': 'Comando enviado correctamente.', 'estado': comando})
    except Exception as e:
        print(f"Error while processing command: {str(e)}")
        return jsonify({'success': False, 'message': 'Error al enviar comando.', 'error': str(e)}), 500

I expect that when I click the button the MQTT message will be sent and the error disappears

Type ‘string[]’ is not assignable to type ‘string’.ts(2322) when trying to create a form using Prisma

so I’m trying to create a submitForm using prisma, react-hook-form and zod and mysql as my database. But the problem I’m encountering right now is I get this error on form-submit.ts

Type 'string[]' is not assignable to type 'string'.ts(2322)

I know this comes from my schema.prisma, because upon reading the docs, on Scalar https://www.prisma.io/docs/orm/reference/prisma-schema-reference#-modifier

model AppoinmentSchedule {
  id String @id @default(cuid())
  doesHaveTCETAssitance String
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt 
}

Since my zod accepts array.

export const formSchemaData = z.object({
    
    doesHaveDryRun:  z.enum(["yes", "no"], {
      required_error: "Please select if yes or not"
    }),
   
  })

form-submit.ts


export const submitForm = async (
    values: z.infer<typeof formSchemaData>
) => {
    const validatedFields = formSchemaData.safeParse(values)

    if(!validatedFields.success){
        return {error: "Form not submitted successfully!"}
    }

    const {
        doesHaveTCETAssitance,
    } = validatedFields.data

    try {
        await db.appoinmentSchedule.create({
            data: {
                doesHaveTCETAssitance,
            }
        })
    } catch (error) {
        return {error: "Something went wrong"}
    }
}

CSS and JS: How to prevent “event.target.innerText” from deleting inside tag

For example, I have a tag like:

<p><a href="mailto:[email protected]">[email protected]</a></p>

When it runs through this:

const repetitions = setInterval(x => {
      originalText = event.target.innerText;
      splitText = event.target.dataset.value.split("");
      event.target.innerText = splitText.map((character, index) => {
        
      if (index < i) {
        return event.target.dataset.value[index];
      } else {
        return codeSymbols[Math.floor(Math.random() * 26)]
      }

It deletes the inner a tag and leaves it with. <p>[email protected]</p>

The event is based off of observing:

const hiddenElements = document.querySelectorAll("h1, h2, p, a");
hiddenElements.forEach(ele => {
  observer.observe(ele);
})

I believe the observing event detects a p, then it targets the p tagname in event.target.tagname, deleting the inner a tag.

How would I prevent this from happening?

Load mixed content on page load with Javascipt

Modern browsers are constantly forcing https for all situations.

Issue: Need to load mixed content

Before the https requests were being force, I could use JS to force the page to reload as http for the camera part of the page. It’s no longer working in many browsers. I have tried all of the easy basic javascript tricks but they have all failed. I’m using squarespace so I can’t override the browser requests server side.

Currently, if the page loads as http: it does the following:

displays a Image from the camera over static IP: http://96.57.87.254:91/live/1/jpeg.jpg with the option to click on a button which goes to another page that loads the RTP video stream.

My only thoughts are to

  1. Force the page down to http, but the browser ignores the protocol
    and loads the page say http://google.com as https no matter what.

  2. Use a CORS proxy for the http content parts? I am not sure how to get that to work with a static IP

  3. Use some 3rd party webste to host it as https.

I’m hoping someone can help me solve one of these or suggest something else.

For example this fails:

<script> 
if (!(window.location.href.indexOf("squarespace") > -1) && (location.protocol == 'https:')) {
    alert("Cameras require that your browser use http connection, switching to it now");
    var URL = 'http://URL.org/'
    var httpAnchor = document.createElement('a');
    httpAnchor.href = URL;
    
    // Trigger a click on the anchor element
    httpAnchor.click();
}


</script>

This for example also fails:

    if (!(window.location.href.indexOf("squarespace") > -1) && (location.protocol == 'https:')) {
    alert("Cameras require that your browser use http connection, switching to it now");
    var URL = 'http://URL.org'
    var xmlhttp;
    if (window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
    }
    xmlhttp.open("GET", URL, true);
    xmlhttp.send();
}

Long delay before completion of a simple firestore-reading script

Getting reoriented after a long time since my last firestore project. Why does this script take an extra 60-90s — after the output — to complete? It works properly except for the mysterious ending…

import { initializeApp } from "firebase/app";
import { getFirestore, collection, query, getDocs } from "firebase/firestore";


const firebaseConfig = {
  // my config
};

const app = initializeApp(firebaseConfig);
const db = getFirestore(app);

async function getSomeFirestoreData() {
  try {
    const ref = collection(db, "MyCollection");
    const q = query(ref);
    const querySnapshot = await getDocs(q);
    querySnapshot.forEach(doc => {
      console.log(doc.id, " => ", doc.data());
    });
    return "done"
  } catch (e) {
    console.log(e);  // we don't get here
  }
}

getSomeFirestoreData().then(r => {
  console.log(r);  // we get here fast (fast enough)
  process.exit();  // terminates fast with this, but I shouldn't need it
});

After a recent install, package.json:

    "node_modules/@firebase/firestore": {
      "version": "4.6.1",
      ...

I see my doc data after a very reasonable delay and I see “done” immediately. Without the explicit exit, node doesn’t terminate for another minute and a half. Why?

How do I pass a JavaScript variable to Flask?

I’m relatively new to JavaScript. I have a function in flask which I want to call, but it requires arguments which can only be defined in JavaScript.

var socket = io();
socket.connect('http://127.0.0.1:5000/');
socket.on('connect', function() {
    console.log('connected')
});

function createSpan() {
    var c = 1
    for (let i of document.getElementsByTagName('li')) {
        var span = document.createElement('span');
        span.id = 'outlineSpan'
        var clonedLI = i.cloneNode(true);
        span.appendChild(clonedLI);
        console.log(i.innerHTML)
        var genNotesBtn = document.createElement('button');
        genNotesBtn.className = 'genNotesBtn';
        genNotesBtn.id = 'genNotesBtn' + c;
        c++;
        genNotesBtn.innerHTML = 'Generate notes.';
        genNotesBtn.onclick = function() {
            socket.emit('notesGen')
        }
        span.appendChild(genNotesBtn);
        i.parentNode.replaceChild(span, i);
        var text = i.innerHTML;
    }
}

How can I use text as the variable for subheading in this SocketIO function:

@socketio.on('notesGen')
def notesGen():
    assistantID = notesGenAssistant()
    subheading = ?
    notesGenThread(subheading, detail)
    notesGenRun(notesGenAssistantID, threadid)

I tried to redeclare var text = i.innerHTML; to var text = '{{ subheading }}', but Flask didn’t recognise the variable.

Remove an element from HTML using Javascript [duplicate]

I am working from a backend system, which doesn’t allow me to edit the HTML but does allow me to add javascript or HTML And CSS in the top or bottom of the page.

I have the following code on the page:

<div class="ext_ui_section_items"><div class="ext_ui_dropdown_item ext_ui_dropdown_item--light"><a href="/user/approvals" tabindex="0" class="ext_ui_dropdown_item_anchor"><div class="ext_ui_dropdown_item_anchor_wrapper"><span class="ext_ui_dropdown_icon_wrapper"><!----></span> <span class="ext_ui_dropdown_item_text">
    Approvals
    </span> <span class="ext_ui_dropdown_item_suffix"><div data-v-2032d9d2="" data-ui-id="countValue" class="badge menu_style_light">
  0
</div></span></div></a></div> <div class="ext_ui_dropdown_item ext_ui_dropdown_item--light" data-ui-id="my-requests"><a href="/user/requests?reporter=ALL_REQUESTS" tabindex="0" class="ext_ui_dropdown_item_anchor"><div class="ext_ui_dropdown_item_anchor_wrapper"><span class="ext_ui_dropdown_icon_wrapper"><!----></span> <span class="ext_ui_dropdown_item_text">
    My requests
    </span> <span class="ext_ui_dropdown_item_suffix"><div data-v-2032d9d2="" data-ui-id="countValue" class="badge menu_style_light">
  0
</div></span></div></a></div></div>

Now the element I want to remove is the FIRST child element in that list named ‘ext_ui_dropdown_item ext_ui_dropdown_item–light’ by class, however, I do not want to remove the entire list, but just that first index. The issue I have is, that they are both named with the same class and removing one removes both of them. Can anyone help?

I have tried

 const parent = document.getElementsByClassName("ext_ui_section_items");
    const child = document.getElementsByClassName("ext_ui_dropdown_item ext_ui_dropdown_item--light");

setting the constants and then trying to remove them via the HTML collection, but it’s confusing me now.

Export data from Excel via an API

I’m currently working on a project that requires me to import data from various excel documents onto a webpage. I can easily import the data via an API, the problem is getting that data out of excel.

I’ve successfully created a script via the script lab addin that enables me to pull all required data out of excel and format it. I’m even able to send it into script lab’s paired html display page. The problem, though, is that I am unsure if it’s possible to send the data elsewhere. Script lab is cloud based so in theory I can send it to an api from there, but I don’t know if it’s possible to import the api library into script lab’s JavaScript text editor. Alternatively, I would have no problem running the script locally on my device and sending the api calls from my computer. However, then I don’t know how to access the data in my excel document. It would all be local at that point so I could in theory do so easily, but I don’t know for sure. Am I just missing something or is this not possible? Is there a different way I should go about this?
