Ext.Msg.show({
title:'Save Changes?',
message: 'You are closing a tab that has unsaved changes. Would you like to save your   changes?',
buttons: Ext.Msg.YESNOCANCEL,
icon: Ext.Msg.QUESTION,
fn: function(btn) {
    if (btn === 'yes') {
        console.log('Yes pressed');
    } else if (btn === 'no') {
        console.log('No pressed');
    } else {
        console.log('Cancel pressed');
    }
}
});

How do I add aria-label “close dialog” to the close icon at the top?

I am unable to add afterRender or listeners

I have a react App which I will be using to bring in google other contacts and I see that theres a limit for 1000 contacts in each call to google People Api’s.

const getGoogleContacts = async (token) => {
        if(!token) throw new Error('Google Auth Token Missing');
        let params = {"readMask" : "emailAddresses,names", "pageSize" : "1000"};
        let url = `https://people.googleapis.com/v1/otherContacts?${new URLSearchParams(params)}`;
       
        let headers = { Authorization: `Bearer ${token}`};
        let rawData = await fetch(url, { headers })
            .then(res => res.text());
        let parsedJson = JSON.parse(rawData);
        let nextPageCheck = checkForNextPageToken(parsedJson);
        if(nextPageCheck){
         //get the next page contacts. 
         }
        return handleRawContactData(parsedJson);
    }
const checkForNextPageToken = (response) => {
        if(response.hasOwnProperty('nextPageToken')){
            return true;
        }
        return false;
    }

I have the following Object type in Flow:

type Identity = {
  name: string,
  lastName: string
};

type ExtraInfo = {
   favoriteColor: string,
   age: number
};

type Person = {
   a: Identity,
   b?: ExtraInfo
};

Is there a way to define from Person a type without any maybe type?:

// final result, but I don't want to redeclare all the properties, I want to derive from the Person type
type PersonWithExtraInfo = {
   a: Identity,
   b: ExtraInfo
};

I thought that by applying this would work, but apparently, not. Maybe becuase it’s not a maybe type what’s defined, but an optional property:

type NonMaybeType = <Type>(Type) => $NonMaybeType<Type>;
export type PersonWithExtraInfo = $ObjMap<Person, NonMaybeType>;

Someone asked this before but not working How do I delete empty columns with the header in google sheet? I still have issues that it shows cannot delete the column but only can hide. How to make the code work?

I am using Mantine for a search bar and I need to get the wordcount of the text area. This is using Nodejs and React. I need to be able to export this value to use in a different file.

import React, { useState } from 'react';
import { TextInput, createStyles } from '@mantine/core';
var count = document.getElementById('count');

const useStyles = createStyles((theme, { floating }: { floating: boolean }) => ({
  root: {
    position: 'relative',
  },
  label: {
    position: 'absolute',
    zIndex: 2,
    top: 7,
    left: theme.spacing.sm,
    pointerEvents: 'none',
    color: floating
      ? theme.colorScheme === 'dark'
        ? theme.white
        : theme.black
      : theme.colorScheme === 'dark'
      ? theme.colors.dark[3]
      : theme.colors.gray[5],
    transition: 'transform 150ms ease, color 150ms ease, font-size 150ms ease',
    transform: floating ? `translate(-${theme.spacing.sm}px, -28px)` : 'none',
    fontSize: floating ? theme.fontSizes.xs : theme.fontSizes.sm,
    fontWeight: floating ? 500 : 400,
  },
  required: {
    transition: 'opacity 150ms ease',
    opacity: floating ? 1 : 0,
  },
  input: {
    '&::placeholder': {
      transition: 'color 150ms ease',
      color: !floating ? 'transparent' : undefined,
    },
  },
}
)
);
export function FloatingLabelInput() {
  const [focused, setFocused] = useState(false);
  const [value, setValue] = useState('');
  const { classes } = useStyles({ floating: value.trim().length !== 0 || focused });
  const uniqueid = "input";
  return(
    <TextInput
      id={ uniqueid }
      placeholder="Add anything you want to the book of the internet."
      required
      classNames={classes}
      value={value}
      onChange={(event) => setValue(event.currentTarget.value)}
      onFocus={() => setFocused(true)}
      onBlur={() => setFocused(false)}
      mt="md"
      onKeyUp={(e) => {
        var text = value.split(' ');
        var wordcount = 0;
        for (var i = 0; i < text.length; i++) {
          if (text[i] !== ' ') {
            wordcount++;
            }
          }
          count.innerText = wordcount;
        }
        }
      autoComplete="nope"
    />
      );
}

As you can see, it correctly outputs it into html, but returning inside the function doesnt work at all.

I tried exporting it, I tried returning it to the function but it doesn’t see it. I tried exporting and using modules exports but that doesnt work either. Any help would be appreciated.

I’m using JS & AJAX to gather info from a Web-API (for a crypto-mining pool). Almost all of it works perfectly, but with the server the way the developer set it up, when a value is not used, it MIGHT be empty, not 0. Others do have a placeholder value (I’m talking with the dev to give everything a placeholder, but until then, I need some help).

e.g.:

{"version":"0.0.3","statusCode":200,"headers":{"Access-Control-Allow-Headers":"Content-Type, Access-Control-Allow-Headers, Access-Control-Allow-Origin, Access-Control-Allow-Methods","Access-Control-Allow-Origin":"*","Access-Control-Allow-Methods":"GET","Content-Type":"application/json"},"body":{"primary":{"hashrate":{"shared":0,"solo":0},"payments":{"balances":0,"generate":0,"immature":0,"paid":0},"shares":{"shared":{},"solo":{}},"times":{"shared":0},"work":{"shared":0,"solo":0},"workers":{"shared":[],"solo":[]}},"auxiliary":{"hashrate":{"shared":0,"solo":0},"payments":{"balances":0,"generate":0,"immature":0,"paid":0},"shares":{"shared":{},"solo":{}},"times":{"shared":0},"work":{"shared":0,"solo":0},"workers":{"shared":[],"solo":[]}}}}

You can see that under body.primary.shares.shared it is just [] and not a zero value.

Here is part of the script:

function avianDashboard(api, workerAPI) {
    const xhr = new XMLHttpRequest();
    xhr.open("GET", api, true);
    xhr.onload = function () {
        if (this.status === 200) {
            obj = JSON.parse(this.responseText);
            if (typeof (obj.body.primary.shares.shared) === 'undefined') {
                document.getElementById('minerShares').innerHTML = 0;
            } else {
                document.getElementById('minerShares').innerHTML = obj.body.primary.shares.shared.valid;
            }

//Rest of the function works properly so I've omitted it for the sake of sanity

When I run the page, the console.log shows this..

uncaught TypeError: Cannot read properties of undefined (reading ‘shared’)
at XMLHttpRequest.xhr.onload (avian.php:784:61)

and points to this line:

if (typeof (obj.body.primary.shares.shared) === ‘undefined’) {

I’ve found a lot of things that are supposed to help with this issue (including using typeof because I was originally just using <1 or null as my conditional checker and that didn’t work either.

Any help would be greatly appreciated.

I am trying to read a local JSON file using JavaScript. The file is in OneDrive however, and I am operating in Codepen. In the browser console, I get a 404 error.

fetch(".UsersmyNameOneDrive - myOrgDocumentsmyFile.json")
  .then(response => response.json())
  .then(json => console.log(json));

Nothing is returning and I get that 404 error. I just want to console.log my json text. I can even convert it to a js file if that works better, but it didn’t work here.

The file location actually reads: C:UsersmyNameOneDrive – myOrgDocumentsmyFile.json , so am I writing the URL wrong? Is there a way to pull from OneDrive that I am missing? Is it because I am using Codepen? I can’t figure it out.

I need sort the but not sure how:

class Stack {
  data;
  top;

  constructor() {
    this.data = [];
    this.top = 0;
  }

  push(element) {}
  pop() {}
}
size() {
  peek() {}
  isEmpty() {

  }
  display() {}
}

How do I solve sortQUsingStack I need to sort input q.display

function sortQUsingStack(q) {
  console.log("input:  " + q.display());
  var st =
    while () {

    }

  console.log("sorted: " + q.display());
}

So I am making a wordle clone in code.org using the dataset, yet I am facing two issues.

The first issue is that when I console.log the correct answer, sometimes it says “null” and other times it works without issue.

The second problem is I don’t know how to make the words yellow if they are out of order or in the word. My code is down below.

//Getting Wordle Answer 
var answers = getColumn("Wordle", "validWordleAnswer");
var index = (randomNumber(0, answers.length));
console.log(answers[index]);
var letters =  ["letter1", "letter2", "letter3", "letter4", "letter5"];


//Checking Words
onEvent("wordbutton", "click", function( ) {
  var guess = getProperty("wordInput", "text");
  for (var i = 0; i < 5; i++) {
   

     if (guess == answers[index]) {
          setProperty(letters[i], "background-color", "green");
        } else if ((answers[index].includes(guess))) {
          setProperty(letters[i], "background-color", "yellow");
        } else {
          setProperty(letters[i], "background-color", "red");
        }
    setProperty(letters[i], "text", guess[i]);
  }
});

Specifically the else if statement, and the first four lines of code that are my variables

I’m trying to simulate the free drawing of a path object inside a fabric.js canvas.

I have a “recording” of the steps inside a javascript object such as :

var dataset = [{
  "type": "move",
  "value": [
    [30, 257, "2022-03-22T10:16:56.882Z"],
    [58, 271, "2022-03-22T10:16:56.898Z"],
    [79, 281, "2022-03-22T10:16:56.914Z"],
    [91, 282, "2022-03-22T10:16:56.931Z"],
    [95, 282, "2022-03-22T10:16:56.948Z"],
    [96, 281, "2022-03-22T10:16:56.963Z"],
    [97, 281, "2022-03-22T10:16:56.981Z"]
  ]
},
{
  "type": "draw",
  "value": [
    [97, 281, "2022-03-22T10:16:57.046Z"],
    [98, 281, "2022-03-22T10:16:57.070Z"],
    [103, 279, "2022-03-22T10:16:57.083Z"],
    [106, 278, "2022-03-22T10:16:57.098Z"],
    [114, 274, "2022-03-22T10:16:57.114Z"],
    [133, 268, "2022-03-22T10:16:57.130Z"]
  ]
}]

value is an array of array containing the coordinates (x, y) on the canvas, and the timestamp. It is the result of a recording of the user interactions on the canvas.

I managed to recreate a moving cursor ("type": "move") but I have troubles recreating the drawing process ("type": "draw") as it involves three mouse events (‘mousedown’, ‘mousemove’ and ‘mouseup’).

For now, I’m using two nested asynchronous functions to navigate inside the object and move the cursor around the canvas.

var time;

autoDrawing(dataset, function() {
   console.log('finished');
});

async function autoDrawing(dataset, callback) {
   time = new Date(dataset[0].time);
   for (let i = 0; i < dataset.length; ++i) {
       await draw(dataset[i]);
   }
   callback();
}

function draw(data) {
    return new Promise(resolve => {
        if (data.type === 'move') {
            console.log('moving');
            moveCursor(data.value, false, function() { resolve('') });
        } else if (data.type === 'draw') {
            console.log('drawing');
            moveCursor(data.value, true, function() { resolve('') });
        } else {
            resolve('');
        }
   });
}

async function moveCursor(moves, draw, callback) {
     // The canvas object is stored inside the DOM element, in the fabric property.
     // This is because I have different canvas for different layers.
     let activecanvas = document.getElementsByClassName('canvas-container active')[0].firstChild.fabric;
     if (draw) {
          activecanvas.fire('mouse:down', {
              x: moves[0][0],
              y: moves[0][1]
          });
          activecanvas.renderAll();
     }
     for (j = 0; j < moves.length; j++) {
          await movement(moves[j], draw);
     }
     if (draw) {
          activecanvas.fire('mouse:up', {
              x: moves[moves.length - 1][0],
              y: moves[moves.length - 1][1]
          });
          activecanvas.renderAll();
     }
     callback();

     function movement(m, draw) {
         return new Promise(function(resolve, reject) {
              let newtime = new Date(m[2]);
              if (draw) {
                   activecanvas.fire('mouse:move', {
                        x: m[0],
                        y: m[1]
                   });
                   activecanvas.renderAll();
              }
              // mousecursor is a circle that substitutes the mouse cursor on an other canvas.
              mousecursor.set({
                   top: m[1],
                   left: m[0]
              }).setCoords().canvas.renderAll();
              // waitMap is just a setTimeout with the duration/callback position inverted
              waitMap((newtime - time) / 1000, function() {
                   time = newtime;
                   resolve('')
              })
         })
     }
}

I’m using the fire method of a fabric.js canvas but I didn’t find any examples, so maybe I’m not using it the right way.

I have the following array.

const slides = [

  { name: 'intro', effect: 'default'},

  { name: 'slide1', effect: 'spin' },

  { name: 'slide2', effect: 'spin' },

  { name: 'slide3', effect: 'spin' },

  { name: 'slide4', effect: 'spin' },

  { name: 'slide5', effect: 'spin' },

  { name: 'slide6', effect: 'spin' },

  { name: 'slide7', effect: 'default' },

  { name: 'slide8', effect: 'rotate' },

  { name: 'slide9', effect: 'rotate' },

  { name: 'slide10', effect: 'rotate' },

  { name: 'slide11', effect: 'rotate' },

  { name: 'outro', effect: 'default' },

]

If i have objects one after another that have the same effect i need to group them into an object that has { type: ‘stacked’, items: [ here will be all the objects with the same effect property }

How can i transform it to look like this?

const slides = [
  { name: 'intro', effect: 'default'},
  { type: 'stacked', 
    items: [
      { name: 'slide1', effect: 'spin' },
      { name: 'slide2', effect: 'spin' },
      { name: 'slide3', effect: 'spin' },
      { name: 'slide4', effect: 'spin' },
      { name: 'slide5', effect: 'spin' },
      { name: 'slide6', effect: 'spin' },
    ]
  },
  { name: 'slide7', effect: 'default' },
  { type: 'stacked', 
    items: [
      {  name: 'slide8', effect: 'rotate' },
      {  name: 'slide9', effect: 'rotate' },
      {  name: 'slide10', effect: 'rotate' },
      {  name: 'slide11', effect: 'rotate' },
    ],
  },
  {  name: 'outro', effect: 'default' },
]

Can anyone help? thank you !

I have 3 time stamps

StartTime: 22:30:00

EndTime: 05:00:00

CurrentTime: 03:00:00

Now if the current time lies between StartTime and EndTime, then I want to print the “CurrentTime”. So in the above example since CurrentTime is between 22:30:00 and 05:00:00, hence I wish to print it.

So I used the following code

const StartTime = new Date("2020-02-22T23:00");
const EndTime = new Date("2020-02-23T05:00");
const CurrentTime = new Date("2022-02-23T0:00");

const StartTimeHours = StartTime.toLocaleTimeString('en-US', { hour12: false });
const EndTimeHours = EndTime.toLocaleTimeString('en-US', { hour12: false });
const CurrentHours = CurrentTime.toLocaleTimeString('en-US', { hour12: false});

if (StartTimeHours < CurrentHours && CurrentHours < EndTimeHours)
{
    console.log("Current Time",CurrentHours);
}

However, since 05:00:00 is less than 22:30:00, hence it is not printing the output. So how do I make it check that the EndTime is between the two time slots

    channel.send(embed).then(m => {
      m.react("<:check:947079937372872704>")
      m.react("<:warning:943421375526355024>")
    }).catch(err => {
      message.channel.send('Error')
    })

This is my code but when the bot doesn’t have add reaction perms it crashes instead of catching it and printing Error

I have a mobile application using react native, and I am using firebase analytics for tracking events and screen views, but I didn’t find the real-time number of users for the app and searched for google analytics but I didn’t find a solution for this, is there any way I can do this

I have onChangeName and onChangeAge functions, but I want to make 1 function from these two.

functions onChangeSomeState does not work, I don’t no why

codesandbox

import "./styles.css";
import { useState } from "react";

export default function App() {
  const [name, setName] = useState("");
  const [age, setAge] = useState("");

  const onChangeSomeState = (setFunc) => (event) => {
    setFunc(event.taget.value);
  };

  const onChangeName = (e) => {
    setName(e.target.value);
  };

  const onChangeAge = (e) => {
    setAge(e.target.value);
  };

  const onSubmit = () => {
    const res = JSON.stringify({
      name: name,
      age: age
    });
    console.log(res);
  };

  console.log(name);
  console.log(age);

  return (
    <div className="App">
      <input
        onChange={onChangeName}
        placeholder="name"
        value={name}
        className="input"
      />
      <input
        onChange={() => onChangeSomeState(setAge())}
        // onChange={onChangeAge}
        placeholder="age"
        value={age}
        className="input"
      />
      <button onClick={onSubmit} type="button" className="button">
        submit
      </button>
    </div>
  );
}

I’m not getting any age value in the console
