I am running a script and I see the following error that the address type is unknown. I am new to typescript so if there is any information needed about Address type let me know:

yarn ts-node manage/deploy-sandbox.ts
yarn run v1.22.19
$ /Users/apple/proj/tonstart/node_modules/.bin/ts-node manage/deploy-sandbox.ts
/Users/apple/proj/tonstart/node_modules/ton/dist/address/Address.js:17
    throw new Error('Unknown address type: byte length is not equal to 36');
          ^
Error: Unknown address type: byte length is not equal to 36
    at parseFriendlyAddress    (/Users/apple/proj/tonstart/node_modules/ton/dist/address/Address.js:17:15)

deploy-sandbox.ts:

import { Cell, contractAddress, StateInit, toNano, beginCell, Address } from  'ton';
import { readFileSync } from 'fs';
import qs from 'qs';
import qrcode from 'qrcode-terminal';

// Create a data cell similar to the initial contract state
const dataCell = beginCell()
.storeUint(0, 32)                        // counter
.storeAddress(Address.parse('/* YOUR ADDRESS */'))
.endCell();

// Load code from build
const codeCell = Cell.fromBoc(readFileSync('./build/hello-world.boc'))[0];

// Calculate address from code & data
const address = contractAddress({
    workchain: 0,
    initialCode: codeCell,
    initialData: dataCell
});

// Prepare init message
const initCell = new Cell();
new StateInit({
code: codeCell,
data: dataCell,
}).writeTo(initCell);

// Encode link to deploy contract
let link = 'https://test.tonhub.com/transfer/' + address.toFriendly({ testOnly: true }) + '?' + qs.stringify({
text: 'Deploy contract',
amount: toNano(1).toString(10),
init: initCell.toBoc({ idx: false }).toString('base64')
});
console.log('Address: ' + address.toFriendly({ testOnly: true }));
qrcode.generate(link, { small: true }, (code) => {
 console.log(code)
});

I was expecting the script to execute. I just tried running it that’s all.

I get the following payload (part of payload I had pasted below):

images%5B2bbe51ff-27ee-4a71-bfeb-97ceaf8a6698.png%5D=iVBORw0KGgoAAAANSUhEUgAAAhIAAAISCAIAAAAWX7HoAAEAAElEQVR4nOz9Wa%2BuWZIehkWs8Z2%2Bec97nzHnyszqGrq7eh5oUSJpWRDJC8uSDBge4QvCEATYhATD8IUHyIZgygQow5RlUxQsAYRINt0DWxTJ6upmdVVX1pBz5pnP2fP%2B5ndeQ4Qv8qSB%2BgG%2Bq7jZt%2FvBelc8EU88sT6An8XP4mfxs%2FhZ%2FCx%2BFj%2BLn8XP4mfxs%2Fj%2FR%2BAXf%2F7m%2F%2B5%2F7OdLlYUdPeU8TQ0ioBQQZV4UnEj2LB2Zm%2Fa0vG

There should be the base64 encoded images. How I can decode it?

function nextSequence(){
    randomNumber = Math.floor( (Math.random() * 4) );
    randomChosenColour = buttonColours[randomNumber];

    gamePattern.push(randomChosenColour);
    console.log(gamePattern);
    playSound(randomChosenColour);

}



function playSound(name){
  $("#" + name).click(function(){
      let buttonAudio = new Audio("sounds/" + name + ".mp3");
      buttonAudio.play();

I searched on various platforms to know the possible cause of this error but I didn’t find my answer.

I have an array of date string. I created a date input field using

$('#mydatefield').datepicker({
multidate:true;
});

Need to add a validation, when someone inputs a date which exists in that array, should be removed with an error message.
Or
Is it possible to disable those dates on datepicker init?

I’m learning how to generate content with API’s, but when I print in screen the generated text does not alignt with the rest of the container.

<body class="container bg">
    <div class="card row border-primary text-center" style="width: 40rem;">
        <img src="../img/meme.jpg" class="card-img-top mx" alt="...">
        <div class="card-body">
          <h5 class="card-title">Best dad jokes!</h5>
          <div class="col-6 joke text-center"></div> 
          <button class="col-6 btn btn-primary" onclick="pulsarBoton()">Pulsa para un nuevo chiste</button>
      </div>
    </div>
    
    <script src="api.js"></script>
</body>

Also I attach the API code too:

const jokeText = document.querySelector(".joke");

  async function buscarChiste() {
    const response = await fetch("https://icanhazdadjoke.com", {
      headers: {
        Accept: 'application/json',
      },
    });

    const joke = response.json();
    return joke;
  }

  async function pulsarBoton() {
    const { joke } = await buscarChiste();
    jokeText.innerText = joke;
  }

The issue is that I need the card to be centered in the screen with all text centered but the generated text only is shown at the left of the card.

Thanks in advance!

Centering the API generated text

I am building an application that uses Python Flask. There is an HTML form that looks like this:

<form method="POST" action="/route_name">
<p>No Annotation<input type="checkbox" value="No annotation" name="mycheckbox" ></p>
<p>Connector<input type="checkbox" value="connector" name="mycheckbox"></p>
<p>Enclosure<input type="checkbox" value="enclosure" name="mycheckbox"></p>
<p>Text<input type="checkbox" value="text" name="mycheckbox"></p>
<input type="submit" value="Submit">

How do I get the checked data in a json file upon the form submission without reloading the page?

I am experiencing the following error in my code: Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘backend’). This error is occurring when I am trying to access the ‘backend’ property of an object, but it is returning as undefined. I have checked my code multiple times and cannot figure out why this is happening.

I am trying to understand the basics of the CSS grid system. I have an image I want to place in the upper left corner. When I place it in the top left corner, for some reason it adds extra space at the top and the left. As well, when I adjust the gap in the CSS, nothing changes, unless I change it to something extremely large (like 300px).

Here is the code I have so far. I tried adjusting the gap, removing the gap, etc.

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <link rel="stylesheet" href="gridgallerycss.css">

    <div class="gallery">
        <figure class="gallery__item gallery__item--1">
            <img src="Emma_Allerd_Images/emmapic1.jpg" class="gallery__img" alt="Image 1">
        </figure>
    </div>


</body>

</html>

CSS

.gallery{
    display: grid;;
    grid-template-columns: repeat(8, 1fr);
    grid-template-rows: repeat(8, 5vw);
    gap: 15px;
}

.gallery__img{
    width: 100%;
    height: 100%;
    object-fit: cover;
}

.gallery__item--1{
    grid-column-start: 1;
    grid-column-end: 4;
    grid-row-start: 1;
    grid-row-end: 6;
}

Passing URL to the website’s inputbox removes forward slashes and reverses the words in URL.
However, passing same URL to other inputboxes (like website’s login page) doesn’t cause issue.

message="https://www.example.com/post/abc-def-ghi-jkl"
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='...']"))).send_keys(message)

Getting below output:

abc-def-ghi-jklpostwww.example.comhttps

Tried using JS via execute_script,

webEle = driver.find_element(By.XPATH, "//div[@class='...']")
driver.execute_script("arguments[0].value=arguments[1]", webELe, message)

but it doesn’t print any value to inputbox.

let ob = {
    head:{next:0}, 
    tail:2
}

let first = ob.head; //{next:0}
ob.tail = ob.head; // {next:0}
let second = ob.head.next // 0
first.next =2

console.log(ob.tail === first). //true
console.log(first.next === second) //false
console.log("first= " + JSON.stringify(first)) //first= {"next":2}
console.log("second= " + JSON.stringify(second)) //second= 0
console.log("ob.tail= " + JSON.stringify(ob.tail)) //ob.tail= {"next":2}
console.log("ob.head= " + JSON.stringify(ob.head)) //ob.head= {"next":2}
console.log(ob)

In these codes, I am so confused that why when the first.next = 2 doesn’t change the variable second?
Can anyone help to explain it? I appricate it.

I can’t seem to be able to disable horizontal scrolling in CSS for iOS. I need the extra width on the side to make room for my navbar so it is essential for me to disable it.

I’ve tried

  overflow: hidden;
  overflow-x: hidden;
  max-width: 100%;
  -ms-overflow-style: none;
  scrollbar-width: none;
}

html::-webkit-scrollbar {
  display: none;
}

body::-webkit-scrollbar {
  display: none;
}```
But I can still scroll horizontally on my iPhone

How to not redraw a marker-cluster on the map if it is already displayed on the map. I tried

markerCluster.setMap(null);

but it clears the markers as well but I want to clear just the marker-cluster without clearing the markers from the map. Can anybody tell? Thanks

I have a filter-button which will update markers, if an info window is open it should remain open when filter-button is clicked but when markers are redrawn the info window gets closed. This is my code:

let markerCluster = null;
const addMarkers = (stores) => {
    // marker and info window event
    const markers = stores.map((store) => {
        const markerLatLng = new google.maps.LatLng(store.latitude, store.longitude);
        const latLng = {
            lat: Number(store.latitude),
            lng: Number(store.latitude)
        }
        let marker = null;
        if (!map.getBounds().contains(latLng)) {
            marker = new google.maps.Marker({
                map: map,
                position: markerLatLng
            });

            marker.addListener("click", () => {
                infoWindow.open({
                    anchor: marker,
                    map: map,
                });
            });

        }
        return marker;
    });

    if (markerCluster) {
        markerCluster.setMap(null);
    }
    markerCluster = new markerClusterer.MarkerClusterer({ map, markers });
}
