I’m trying to achive the slider functionality, where I want to slider to move to the next question after every three seconds [this part is working fine]

Features i’m trying to achive:

OnMouseEnter: Timer stops, css aniamtion stops(working)
OnMoveleav: Start the timer from remaning time left
OnClick: Change Question number to the selected items (working) and start aniamtion

The issue is when I changed the question_number by onClick event, the next question start showing after every 1 seconds instead of 3 seconds. I think the problem is somehow with the React Re-redendring.

setSlider is simple useState has object:

`

const [ timeSlider, settimeSlider ] = useState({
    question_lenght: 4,
    question_number: 0,
    current_time: 0
  });

`

I’m using useEffect to check the viewport width so react Re-render the components everytime, Viewport changes

I tried to store the Interval for timmer in a react useRef. but still not working. Here is my code:

I use useRef, so I can Resume, Pause and updateNumber outSide where the first time setInterval started
const interval = useRef(null);

After EverySecond update the useState: Seconds

`

useEffect(() => {
    setRemaining({  start_time: Date.now(), stop_time: 0 });
    interval.current = setInterval(() => {
      setSeconds(seconds => seconds + 1);
    }, 1000);
    pauseSlider();
    return () => clearInterval(interval);
  }, []);

`
And when ever the seconds state changed, I make sure after every three seconds. question_number increased only when its less than 3

`

useEffect(() => {
    if (seconds === 3) {
      setSeconds( seconds => 0 );
      settimeSlider( prev => prev.question_number === 3 ? { ...timeSlider, question_number: 0 } : { ...timeSlider, question_number: timeSlider.question_number + 1 } );
    }
  }, [seconds]);

`

Below are the pause, resume and udpate function.

`

function pauseSlider(){
    setSliderHover(true)
    setRemaining({  start_time: 0, stop_time: Date.now() });
    clearInterval(interval.current);
  }
  function resumeSlider(){
    setSliderHover(false)
    setRemaining( prev => ({ ...prev, start_time: prev.stop_time, stop_time: 0 } ));
    interval.current = setInterval(() => {
      setSeconds(seconds => seconds + 1);
    }
    , 1000);
  }
  function updateNumber(num){
    setSliderHover(false)
    setSeconds(0)
    setRemaining({  start_time: 0 , stop_time: 0 });
    clearInterval(interval.current);
    interval.current = setInterval(() => {
      setSeconds(seconds => seconds + 1);
    }
    , 1000);
    settimeSlider( { ...timeSlider, question_number: num } );
  }

`

The Problem could be in these functions, I tried to use setTimeout instead of setInterval same results.

Below is the picture of slider, so you have more clear idea what i’m trying to achive.

i wanna know how to deploy my app. I tried but I got it deployed but I don’t know how to link my telegram not url with firebase hosting.

Look at that now someone helped me deploy a project and after setting it up he requested for my telegram bot url to make it that way. Now I can put my company domain in the telegram bot, and then the firebase domain will redirect to my company domain

I’m trying to convert an array into an object

"loanArray" : [
   {
    "recordID" : "LKOCH123",
    "date" : "20221206",
    "productId" : "21023"
   }
]

I’ve converted this in to Object using Object.assign like below:

let loanObj= Object.assign({}, loanArray)

"loanObj" : {
   "0": {
    "recordID" : "LKOCH123",
    "date" : "20221206",
    "productId" : "21023"
   }
}

However I want to remove that “0” position in my object and the expected is below:
please help to achieve this structure.

"loanObj" : {
    "recordID" : "LKOCH123",
    "date" : "20221206",
    "productId" : "21023"
}

I’m working on a project where I have multiple variables, usually 3 to 6, and each variable has 2 values (placed in an array). I need to compare and subtract value 1 of Variable X to value 2 of Variable Y, and value 1 of Variable Y to value 2 of Variable Z and so on.

How would I accomplish this? (Bonus points if you tell me how to modify the numbers in the arrays before comparing them. How do you modify only a single value in a string and not the whole string itself?)

Here are some examples of a few variables:

let p17 = ["2", "4"];

let p33 = [“3”, “3”];

let p64 = ["5", "6"];

let p28 = [“6”, “2”];

p17's 2 goes to p28's 2, equaling 0.
p33's 3 goes to p17's 4, equaling -1.
p64's 5 goes to p33's 3, equaling 2.
and p28's 6 goes to p64's 6, equaling 0.

Note: I have 136 variables in this project that need to follow this formula, variables being pulled randomly (but I can work the rng part out).

I am new to google apis and was navigating around google chat api. I followed their steps in creating app and authenticating users. However, when I tried it on postman, I get an error:errorInPostman. Can somebody help me on getting tokens using service account in postman?. Thank you in advance!

I already tried to use the service account’s Client ID and put it on postman but I am having a redirect_uri mismatch error. Where can I put the redirect_uri on service accounts?

I’m not able to get Leaflet to load the tiles of my map past the first row in this Vue 3 component. I’ve tried declaring the vertical size of its div several ways, as well as calling map.invalidateSize() when the component is mounted, but without any success.

<script setup lang="ts">
import { onMounted } from "vue";
import * as L from "leaflet";
import "leaflet/dist/leaflet.css";

onMounted(() => {
  var map = L.map("map", { attributionControl: false }).setView([0, 0], 0);
  L.tileLayer("http://127.0.0.1:7800/{z}/{x}/{y}.jpeg", {
    maxZoom: 0,
    noWrap: true,
  }).addTo(map);
});
</script>

<template>
  <h1>Map Detail</h1>
  <div id="map"></div>
</template>

<style>
#map {
  width: 100%;
  height: 512px;
}
</style>

I was using express and the render function to load different pages of my website. However, I have decided to just go with vanilla js instead. The goal is to load the html file and all the js/css stuff too. Here is my code:

server:

const http = require('http');
const fs = require('fs');
http.createServer((req,res) => {

    res.writeHead(200, {'Content-type': 'text/html'})
    fs.readFile('./index.html', null, (err, data) => {
        if(err){
            res.writeHead(404);
            res.write('File not found')
        }else{
            res.write(data)
        }
        res.end();
    })

}).listen(3000);

html file:

<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">
      <link rel="stylesheet" href="./styles/main.css">
      <script src="./src/global.js" defer></script>
      <title>Test</title>
  </head>
  <body>
      <div id="scene-lobby" class="scene">
        hello this is a test
      </div>
      <button id="button1">click me</button>
  </body>
</html>

when I load the webpage, the html file loads, but the css and javascript don’t. Also, I get this error regarding the javascript file:

Uncaught SyntaxError: Unexpected token ‘<‘ (at global.js:1:1)

Does anyone know how to fix this?

I am trying to map an array of strings

arrString = [
      ["A", "B"],
      ["C", "D"],
      ["E", "F"],
      ["D", "A"],
      ["F", "C"],
      ["G", "E"]
    ] 

based on an object of key values:

map =  {
  '0': 'A',
  '1': 'B',
  '2': 'C',
  '3': 'D',
  '4': 'E',
  '5': 'F',
  '6': 'G'
}

into an array of numbers

arrNum = [
      ["0", "1"],
      ["2", "3"],
      ["4", "5"],
      ["3", "0"],
      ["5", "2"],
      ["6", "4"]
    ] 

This is what I have done:

    const map = {}
    const arrNum = Array.from(new Array(arrString.length), () => new Array(arrString[0].length).fill([]));
    for(let i = 0; i < arr2.length; i++){
        map[i] = arr2[i]
    }
    for(let ele in arrString){
    // I can't figure out how to if the obbject value is equal to ele push it's key to arrNum
        if (Object.values(map).includes(ele)) 
    }

As you can see I am trying to loop through arrString and then if any element equals a value in map I want to add its key to arrNum.

So anyone knows how to do it so I can end up with arrNum?

I’m doing this for some kind of school work thing, it said that ill need to do a palindrome checker but all the other things I’ve searched seem to use a different method.

I tried using

var what = prompt("i am asking for a word");
console.log(what)

for (var i = what.length - 1; i >= 0; i--) {
    console.log(what[i])

after that I’m pretty much lost. I wanna know what I can do and use after that.

Currently I am looking for some help with my mouse over event.

<div class="video-container">
<video id="my_video" loop muted poster="IMAGE_URL"> <!-- put your image here -->
  <source src="VIDEO_URL" type="video/mp4"> <!-- path to your video here -->
</video>
</div>

Above is my video-container, on my index page I am displaying 10 videos. Each of them should show a preview of the video when being hovered, however with my current javascript only the first video with my_video id is displaying the video preview when hovering.

let myVideo = document.getElementById("my_video");
myVideo.addEventListener("mouseover", () => {
    myVideo.play()
    image.style.display = 'none'
});

myVideo.addEventListener("mouseleave", () => {
    myVideo.pause();
});

How can I make it so that all videos on my homepage, behave in the same manner?
