Issue

I’m testing a React component that renders checkboxes from a third-party library. I assign each checkbox a ref using useRef({}) and attach a change event listener in useEffect. This works in the browser, but in tests, console.log of ref.current is empty and the listeners are never added.

Setup

Component:

const checkBoxRef = useRef({});

useEffect(() => {
console.log(checkBoxRef.current)
  Object.entries(checkBoxRef.current).forEach(([_, el]) => {
    if (el) el.addEventListener("change", () => {});
  });
}, [fields]);

<Checkbox
  ref={(el) => { checkBoxRef.current[index] = el; }}
  checked={fieldItem.value === "Yes"}
/>

Mock:

jest.mock("external-checkbox-library", () => ({
  Checkbox: React.forwardRef(({ checked, ...props }, ref) => (
    <input ref={ref} type="checkbox" checked={checked} {...props} />
  )),
}));

Question

• How can I properly test that refs are assigned and listeners attached?

Looking for best practices when working with refs in tests, especially with third-party components.

i have used commands like

HELP ME FIX IT (i used chat gpt too build it is trying to waste my time going to offtopic always and not fixing my error)

Sure! Here’s an expanded version of the theory-based async question body that meets the 220-character minimum for Stack Overflow:

Body:

I’m trying to get a deeper understanding of how JavaScript handles asynchronous behavior. I often hear about the call stack, event loop, task queue (aka callback queue), and microtask queue, especially when dealing with things like setTimeout, Promises, and async/await.

I get that JavaScript is single-threaded and uses the event loop to manage asynchronous code, but I don’t fully understand how these parts interact. Specifically:

• What exactly is the difference between the task queue and microtask queue?
• Why does a Promise.then() run before a setTimeout() even when both are async?
• How do async/await and Promise chains fit into the microtask queue?
• In what order are these executed when mixed together?

A clear breakdown of how these pieces work together (especially with an example or timeline) would be really helpful. I want to write more predictable asynchronous code and avoid hidden timing issues. Thanks!

I am trying to embed a youtube video in my react.js website, I have tried multiple different code samples in my file as seen below:

<h1>Embedd Test1</h1>

<YouTube videoId="6pH4Ot-vFlc" />

<div>
    <iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture;"
        allowfullscreen="" frameborder="0" height="315" src="https://www.youtube.com/embed/nqO6cEbXyKM"
        width="560"></iframe>
</div>

<h1>Embedd Test2</h1>
<iframe width="420" height="315" src="https://www.youtube.com/embed/fnqO6cEbXyKM"></iframe>

<h1>Embedd Test3</h1>
<iframe width="872" height="499" src="https://www.youtube.com/embed/nqO6cEbXyKM"
    title="Error fixed &quot;www.youtube.com refused to connect&quot; when trying to embed video in blogs or html page"
    frameborder="0"
    allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share"
    referrerpolicy="strict-origin-when-cross-origin" allowfullscreen>
</iframe>

But all of my embedded youtube videos always appear as “www.youtube.com refused to connect.” both on localhost or in production at the url here: https://jermasearch.com/discogs2youtube

How can I embed YouTube videos in my react.js website? Is it a cors issue?

I’ve uploaded a first set of files to my GitHub account as follows (no gaming logic, only layout and GUI aspects so far):

• GameBoard_TargetAndFleet__iter01.tar

This is an iteration in the development of the GUI for an internet-based, peer-to-peer, browser-to-browser, 2-player version of the well-known Battleship game.

The development status is “early stages of methods selection”. I am absolutely a novice JavaScript programmer, having only done programming by example, leveraging my previous professional experience with other languages (C, Pascal, Bash, Fortran, Graftek Agile) and some very limited ad-hoc Python programming.

At this point, because other approaches did not appear to be as simple or workable, the “iframe” approach for “importing” external content has been used, but with apparent limited success. The issue encountered are:

• the apparent inability to fully control the sizes and placement of iframes within clearly defined parent “div” elements (inconsistencies between grid specifications and element style values required to make things “fit”);

• the apparent inability to use “global” CSS files for content within the iframes; and

• the apparent inability to reference “global” JavaScript variables/objects from within the iframes.

It would be much appreciated if anyone could offer specific/detailed

• explanations as to why these issues have arisen, and

• coding changes that would address the issues encountered, while adhering to the conditions of using ONLY basic vanilla JavaScript, no external web-based libraries/frameworks, so that two independant, non-co-located computers could play the game with nothing more than installing distro-standard packages/libraries that have purely desktop-based dependencies (no use of third-party resources; Is this even possible ???).

I’m beginning to suspect possible impact/restrictions originating from “Content Security Policy”, but different attempts at setting that in the tag have failed to produce any visible change in behaviour or rendered output.

Thank you in advance for sharing your insights and experience.

Current Layout of GUI (work-in-progress):

I am working on a simple animal card shuffle game using plain JavaScript, where:

The user selects an animal card.

Then presses “Start” to shuffle the cards randomly at a selected speed.

After shuffling, all cards are hidden, and the user has to guess their chosen animal.

I tried assigning the user’s selected animal to a variable before the shuffle and then comparing it during the guessing phase. I expected that when the user clicked the correct hidden card, the game would recognize the match and display a “Correct” message while updating the score. However, sometimes even after clicking the right card, it incorrectly shows “Try Again.” I suspect the issue lies in how the selection and guess are being handled after shuffling

function transferOwnership() {

  const fileId = "some-sheet-id-that-i-own";
  const newOwnerEmail = "[email protected]"
  const file = DriveApp.getFileById(fileId);
  const owner= file.getOwner().getName();
  
  console.log(owner); // Successfully loggs my name
  file.addEditor(newOwnerEmail); // Successfully adds newOwnerEmail as an editor
  file.revokePermissions(newOwnerEmail); // Succesffully removes newOwnerEmail as an editor 
  file.setOwner(newOwnerEmail); // Returns Access Denied Exception. 

}

I added the .addEditor and .revokePermisisons methods to showcase that the drive api works and I’m able to execute them without error. If you give this a try on your own I believe you’d run into the same issue. I wanted to pass the fileId as an argument to use the function within a for loop in order to transfer ownership for some of the files and sheets I own to my other account instead of doing it manually. But when I try to run this function the .setOwner() method always gives me the Exception: Access denied: DriveApp error.

I got stuck with the documentation and when I tried to use gpt it gave the following reason:

If you’re using a Gmail account (e.g. @gmail.com) and trying to transfer ownership to another Gmail account, setOwner() will always fail — even though the method exists and no clear error is in the docs.

✅ This only works in Google Workspace, and only within the same domain (like [email protected] → [email protected]).

Thing is I don’t really trust it because I usually get mistakes when using it for code, and when I tried to google if the domain is the reason I found nothing, also the documentation https://developers.google.com/apps-script/reference/drive/file doesn’t say anything about exceptions. I feel very stuck here and would appreciate any help or work around or even a discussion.

Thank you.

I’m using odoo for my webstore and want to an “inquire” button on each product that goes to contact page with the product name passed in the url and then autofilled into the contact form.
Currently, I have been able to get the url to pass the variable as so mywebsite.com/contactus?product_name=Productname I also have a script on the contact page that should be inputting it into the form.

function getQueryParam(param) {
   const urlParams = new URLSearchParams(window.location.search);
   return urlParams.get(param);
   }
const productName = getQueryParam('product_name');
if (productName) {
   const productField = document.getElementById('product_name');
   if (productField) {
      productField.value = decodeURIComponent(productName);
   }
}

What seems to happen is that the moment the page loads it gets filled and then immediately gets cleared. Not sure why though. Here’s the code to the webpage- I’m trying to autofill into the “Subject” which id is “obmoxynau18w” on the form (I think that’s an odoo thing):

I’ve been coding my web-scraping app for 2 weeks now and after designing and everything I found out that the site i want to scrape started using cloudflare, in my previous app i used python so I simply used cloudscrapper library to bypass it but i couldn’t find a dart equivalent.

I tried some solutions:

1. I tried building an api with flask and python and let the app communicate with the api and it worked but i cant provide a 24/7 hosting for my api.
2. I also tried bypassing cloudflare using the cookies in the header of the http request but it didn’t work 🙁
3. I learned that cloudflare checks if the browser has javascript enabled or not, then i thought “if i have a js enging in dart i could theoretically bypass cloudflare” but i couldn’t find a JS engine in dart.
   I’m kinda stuck here and i dont know what to do anymore, i think i wasted 2 weeks of UI development but I hold my hopes high for this post, pls help :'(

I’m trying to create a simple block in HTML, CSS, and eventually JS.

The overlay cover the whole screen, the texts are white, basically, i need to cut the overlay where there are the video-gap divs to show the video under the overlay. I have no idea how to do it, someone can give me some advice or tell how to achieve this result?

Is it possible to achieve it only with CSS or CSS+JS?

I have found a way to display a portion of an array using arrayName.slice(start, end), i made a funtion to feed the start and end to the slice method so i can use it with onClick button to click next 3 element to show in HTML.

my problem is the increment funcion doesn’t start with zero(0), it start with 3- 6, and when i press next it start from 6 – 9.
it is working proberly but not starting from zero

    const array = ["a1","a2","a3","a4","a5","a6","a7","a8","a9","a10","a11","a12","a13","a14","a15"]

let next = {
        start: 0,
        end: 0,
        incrementby: 3,
        inc() {
          this.start = this.start = 0 ? 0 : this.start + this.incrementby;
          this.end = this.start + this.incrementby;
          console.log(this.start, this.end);
          displayHadith(this.start,this.end)
        },
      };
      
 function displayHadith(start,end) {
        var container = document.querySelector(".container");
        container.innerHTML = ""
        let some = array.slice(start, end);
         for (let element of some) {
          container.innerHTML +=`
          <div class="sharh" >${element}</div>
          `
         }
        }

<button onclick="next.inc()">clickNext</button>
<div class="container"></div>

Stack Overflow! This is my first question around here, and i’ll be thankful to know one thing:

If there is an JavaScript method (library, framework) for storing data (.xml, local data, etc..) for more expansive THAN the LocalStorage uses. (5MB)

Thank you all!

I thought that LocalStorage could possibly expand storage to more than that small 5MB.

I have been tasked with implementing the following design using Chart.js:

Almost everything’s been implemented (via the Chart.js documentation):

const chart = new Chart(document.getElementById('chart'), {
    type: 'line',
    data: {
        datasets: [{
            label: 'Line 1',
            data: line1Values, // Set earlier in the code
            borderColor: '#E66FD2',
            backgroundColor: '#E66FD2',
            pointStyle: 'circle',
            pointRadius: 4,
            borderWidth: 2,
            lineTension: 0.4
        }, {
            label: 'Line 2',
            data: line2Values, // Set earlier in the code
            borderColor: '#8C6FE6',
            backgroundColor: '#8C6FE6',
            pointStyle: 'circle',
            pointRadius: 4,
            borderWidth: 2,
            lineTension: 0.4
        }]
    },
    // More configuration
});

The one thing not implemented is the little gaps that are between the dots and the lines on the chart. Is there a way to add them in Chart.js? Do I need a custom plugin?

Is anyone familiar with Google Appscript?

I’m using an api to fetch replies sent via Telnyx sms and populate those replies into my sheet one row at a time.

I ran the script successfully several times today getting as much as 10 replies.

Now I’m getting this error and I don’t know how to fix it.

I can clear the sheet and run the script. It fails after the 4th reply is fetched with the following pictured error:enter image description here

 var API_KEY1 = "";  // Replace with your real Telnyx API key


function fetchInboundMessages() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
    sheet.clearContents();
  sheet.appendRow(["From", "To", "Message", "Received At"]);


  // Step 1: Get message detail records (only inbound messages for today)
  var url = "https://api.telnyx.com/v2/detail_records?filter[record_type]=messaging&filter[date_range]=today&filter[direction]=inbound";


  var response = UrlFetchApp.fetch(url, {
    "method": "get",
    "headers": {
      "Authorization": "Bearer " + API_KEY1,
      "Accept": "application/json"
    }
  });


  var records = JSON.parse(response.getContentText()).data;


  // Step 2: For each message, get the full message content using the message ID
  records.forEach(function(record) {
    var messageId = record.id;


    var messageResponse = UrlFetchApp.fetch("https://api.telnyx.com/v2/messages/" + messageId, {
      "method": "get",
      "headers": {
        "Authorization": "Bearer " + API_KEY1,
        "Accept": "application/json"
      }
    });


    var messageData = JSON.parse(messageResponse.getContentText()).data;


    var from = messageData.from.phone_number;
    var to = messageData.to[0].phone_number;
    var text = messageData.text || "[No Text]";
    var receivedAt = messageData.received_at;


    // Step 3: Write each row to the sheet
    sheet.appendRow([from, to, text, receivedAt]);
  });
}
