Click event not working when using arrow functions (jQuery) [duplicate]

I want to add a class to an <h1> element when I click on it. I am using an arrow function, but it is not working.

Here is my code:

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.6.0.min.js"></script>
        <link rel="stylesheet" href="css/style.css">
        <title>Test</title>
    </head>
    <body>
        <h1>Click me!</h1>
        <script src="js/script.js"></script>
    </body>
</html>

$(document).ready(start)

function start(){
    $('h1').click(()=>{
        $(this).toggleClass('h1-click')
    })
}

How can I run a function inside of a function in NodeJS? [duplicate]

class TestClass {
    async profile() {
        await ClientData (BASE_URL, function Data (response) { // ClientData is using `export async function` in another file that has function for getting body from a website url
            return response
        })
    }
}

const Client = new TestClass();
async function test() {
    console.log(await Client.profile().Data());
}

test();

It always give an output (node:5424) UnhandledPromiseRejectionWarning: TypeError: Client.run(...).Data is not a function, I do tried one thing previously with this:

async function test() {
    console.log(await Client.profile().Data);
}

test();

Instead of getting the output, it just gives me output undefined

How to display different data types in radial stacked chart using D3?

I’m trying to display data in a radial chart/donut chart where there is a threshold and an overshoot. The data I am displaying is in percent, tonnes, kg per capita, scale(0-1). I’m guessing I would have to convert the data to a common type like percent, but I’m unsure how to go about it.

The chart is supposed to look like this

Another example

Here is a snippet of the data:

Planetary Boundry Threshold Overshoot
Climate Change – 2.35 tonnes CO2 equivalent per capita yearly 18.95 tonnes CO2 equivalent per capita (2020)
Ocean acidification – 1.59 tonnes CO2 per capita yearly (until 2055) 15.33 tonnes CO2 per capita (2020)
Nitrogen 100% good or very good ecological condition (limit between moderate and good = 250-775 µg/L) 72.7%
Biodiversity / land use 0.6 (scale 0-1) 0.45

Ramda JS – Pass optional argument to the second function of a pipe

I am trying to refactor this code:

async function getUserDataByUsername(username, cached = true) {
  const usernameRef = firestore
    .collection("usernames")
    .doc(username.toLowerCase());

  const usernameDoc = await usernameRef.get();

  if (!usernameDoc.exists) {
    throw userErrors.userNotFound();
  }

  const { userId } = usernameDoc.data();

  return memoizedGetUserData(userId, cached);
}

For that, I have thought to split it in smaller parts, as follows:

function memoizedGetUserData(userId, cached = true) { 
  ... Fetching from LRU or DB ... 
}

async function getUserId(username) {
  const usernameRef = firestore
    .collection("usernames")
    .doc(username.toLowerCase());

  const usernameDoc = await usernameRef.get();

  if (!usernameDoc.exists) {
    throw userErrors.userNotFound();
  }

  const { userId } = usernameDoc.data();

  return userId;
}

async function getUserDataByUsername(username, cached = true) {
  const userId = await getUserId(username);

  return memoizedGetUserData(userId, cached);
}

Now, I want to apply Ramda to this module. I have never used this library before, but I have read that it is really cool, and makes the code easier to understand with some of it utilities.

What I am trying is to refactor the original method using the pipeline style, as follows:

import R from "ramda";

...

const getUserDataByUsername = R.pipeP(getUserId, memoizedGetUserData);

But… how can I pass the second optional parameter “cached”, only to the second argument of my pipe??

How to split object into multiple objects by props names in JS

I am trying to split object into multiple objects. Here is how it looks. It is actually array of objects.

[
  {
    interval_9_gun_time_milliseconds: 0,
    interval_9_net_time_milliseconds: 0,
    interval_9_gun_pace: '00:07:04',
    interval_8_gun_time_milliseconds: 0,
    interval_8_net_time_milliseconds: 0,
    interval_8_gun_pace: '00:07:04',
    entry_id: 200
  },
  {
    interval_9_gun_time_milliseconds: 0,
    interval_9_net_time_milliseconds: 0,
    interval_9_gun_pace: '00:02:04',
    interval_8_gun_time_milliseconds: 0,
    interval_8_net_time_milliseconds: 0,
    interval_8_gun_pace: '00:04:04',
    entry_id: 404
  },
  {
     entry_id: 1
  }
]

So expected result should be:

 [
      {
        interval_9_gun_time_milliseconds: 0,
        interval_9_net_time_milliseconds: 0,
        interval_9_gun_pace: '00:07:04',
        entry_id: 200
      },
      {
        interval_8_gun_time_milliseconds: 0,
        interval_8_net_time_milliseconds: 0,
        interval_8_gun_pace: '00:07:04',
        entry_id: 200
      },
      {
        interval_9_gun_time_milliseconds: 0,
        interval_9_net_time_milliseconds: 0,
        interval_9_gun_pace: '00:02:04',
        entry_id: 404
      },
      {
        interval_8_gun_time_milliseconds: 0,
        interval_8_net_time_milliseconds: 0,
        interval_8_gun_pace: '00:04:04',
        entry_id: 404
      }
    ]

Bottom line split and group object by interval_{number} and add other props, if object doesn’t have interval remove it.

addeventListener not working on all elements

Hello I mam facing a problem with my script.

I am beginner in JS and I am trying to add event listener to buttons generated by a foreach but only the last button generated is responding to the addeventlistener.

I am also facing a pb of variable range with the getLocation(flight) function which is returning undefined outside the fuction while the console.log in the function is displaying the good variable value.

Can someone help?

custom columns selection google script

I’m using a google script to save a google sheet as a csv daily, I would like to only save desired columns (in this case columns 1,2,4,9,14,25,26 and 44).
I tried to modify the range, an if after columns loop, putting only the wanted columns as i value for columns loop… but the script still saves the whole google sheet. Any ideas ? Thanks

How to adjust the space between heading, legend and plot area on Plotly?

NodeJS Streams: Readable.pipe() doesn’t send data immediately

From what I understood about streams, Stream.Readable.pipe() should pipe the data as soon as it receives it.

I am trying to implement my own streams but the output is not as expected.

const { Writable, Readable } = require("stream");

const writable = new Writable();
writable.data = [];
writable._write = (chunk, encoding, next) => {
  writable.data.push(chunk.toString());
  console.log(chunk.toString());
  next();
};

const readable = new Readable({
  read() {},
});

readable.pipe(writable);
readable.push("hi");
writable.write("ho");
writable.write("ho");
console.log(writable.data);

The output of this code is

ho
ho
[ 'ho', 'ho' ]
hi

The pipe is writing to the stream later. What does this mean?

Trying to implement a basic search engine by hiding elements that aren’t results, but my code hides everything instead

I am trying to implement a very basic search engine. I iterate through an array of objects, checking if my search term matches some attributes, and if it does, I push each matching object onto an array. Now, in the rest of my code I have it so each object is represented by an element, and each element has a checkbox. Each checkbox has an ID that matches its object’s ID. So…. when I run the search function, I take the matches, correspond them to a checkbox through the IDs, and then I want to hide the elements that don’t match.

The problem is: it hides ALL the elements, instead of just the non-matchings IDs. Furthermore, it works when I want to manipulate the matches (say, surround them in a white border). Thank you for your time I look forward to your input.

Blake

function search() {
     var results = [];
     userData.forEach(task => {
         if (task.value.toLowerCase().includes(searchBar.value.toLowerCase()) 
             || task.note.toLowerCase().includes(searchBar.value.toLowerCase())) {
                 results.push(task.id);
             }
         })

         const checkboxes = document.querySelectorAll(".checkbox");

         checkboxes.forEach(checkbox => {
              if (!results.includes(checkbox.id)) {
                   checkbox.parentElement.style.display = "none";
              }
          })
     }
}

How to pass data between users and different browsers in React?

I am learning React and I’m making an app to better learn.
I created an app with Nodejs backend, Postgres DB and React frontend. I have different users and this is the case of what I need to do:

USER 1: Logs in mozilla and clicks a button on a page.
USER 2: Logs in firefox and sees a new button has appeared, because user in mozilla clicked it. Now he clicks this new button.
USER 1: Because USER 2 clicked new button, USER 1 sees something new displayed.

I am running it locally.

Do something when Promise outside then finished

Here is the code.

function getPromise():Promise<any> {
    let p = new Promise<any>((resolve, reject) => {
        //some logical
        resolve(data);
    });
    p.finally(()=>{ 
        //I want do something when outside then finished! 
        console.log("finally hit");
    });
    return p;
}

function doPromise():void {
    getPromise().then(data => { console.log("then hit"); });
}

But the finally runs before then. So how can I do something after outside then.

I do not want to add finally after then, because the promise called many places. so I want do it in one place.

import React from 'react';
import {BrowserRouter as Router, Route, Switch, Link } from "react-router-dom";
import TestRoute from './TestRoute';
//import Reactapp from './Reactapp';
import ReactComponent from './ReactComponent';

export default function Root(props) {
  return (
    <Router baseName='/react'>
       <Switch>
          <Route path="/" component={ReactComponent} />  
          <Route path="/childroute" component={TestRoute} />  
       </Switch>
    </Router>
    
  )
}
//ReactComponent.js
import React from 'react';
import { Link } from 'react-router-dom';

const ReactComponent = () => {
    return(
        <div>
            ReactComponent
            <Link to='/childroute'>Child Route</Link>
        </div>
    )
}
export default ReactComponent;
//TestRoute.js

import React from 'react';

const TestRoute = () => {
    return(

import Root from "./root.component";


const lifecycles = singleSpaReact({
  React,
  ReactDOM,
  rootComponent: Root,
  errorBoundary(err, info, props) {
    // Customize the root error boundary for your microfrontend here.
    return null;
  },

React hooks onClick icon change is not working

I want to change my icon onClick. But for some that is not working. What I have done is that, if there is submenuIcon1, it will be rendered. If someone clicks on the submenu option, it will render the submenuIcon2, based on the clicked variable.
Maybe I have done something wrong in the ternary operations. Please can someone help me regarding this?
Required Behavior
Whenever clicking on the submenu options, the icon will change. In this case it will be from submenuIcon1 to submenuIcon2.
Current Behavior
Clicking on the submenu options, the icon doesn’t change.
What I have done so far is that,

const SidebarTitle = () => {
  return (
    <>
      <Box
        width='200px'
        height='160px'
        textAlign='start'
        bgColor='#473198'
        px={5}
        borderRadius={2}
      >
        <Text fontSize='2xl' color='white' fontFamily='Fjord One'>
         Some title
        </Text>
      </Box>
    </>
  );
};

export default function Sidebar() {
  const [selectedSubMenu, setSelectedSubMenu] = useState("");
  const [clicked, setClicked] = useState(false);
  let location = useLocation();

  const handleClick = (title) => {
    setClicked(!clicked);
    if (title === selectedSubMenu) {
      setSelectedSubMenu("");
    } else {
      setSelectedSubMenu(title);
    }
  };

  return (
    <div>

I’m developing a site with react and nextjs. So in the API folder, I write some API endpoints. Now I don’t know how can I protect them from clients?
I want to use these APIs directly from the site. and I won’t the user be able to access API from his browser.
