Javascript Object Structure Without Key

I am trying to generate an object structure like so:

{nums: {500: 0, 600: 0}}

I have a function that loops and returns numbers as shown in object: 500 & 600. However,

No matter what I try to create an object structure like the above, it does not work.

This is what I have an array of object as follows :

 const scores = [ {score: 500}, {variant_id: 600} ]

How can I loop through the scores array of object and get a structure like:
Number 0 in this example as a value that will be applicable to all scores.

 {nums: {500: 0, 600: 0}}

What I have done is:

  let filteredScores = [];
  for (let i = 0; i < scores.length; i++) {
            const element = scores[i];
            filteredScores.push(element);
  }

However, this does not lead to the desired results.

Any insights or input is much appreciated!

Convert this JavaScript to Jquery [closed]

Here is what I need to convert. Any help would be greatly appreciated! TIA!

document.getElementById("color1").addEventListener("click",
            function() {
                document.getElementById("JS1").style.backgroundColor = 
                    document.getElementById("color1").value;
            });

Here is what I’ve tried so far.

$('#color1').on('click',function(){
            $('#JS1').css('background-color',$('#color1').val());
                });

any idea how to track a div dynamic Hight increase during an iteration?

Any idea how to track a div dynamic Hight increase during an iteration?
my issue here is I am getting the total height of the items rather than the height being increased on every iteration?

{items.map((item) => {
                if (document.getElementById('divtotrack')) {
                  let clientHeight = document.getElementById('divtotrack')!.clientHeight;
                }
                return (
                  <div>
                    <item
                      key={item.id}
                      id={item.id}
                      content={item.content}
                    />
                  </div>

Adding Chart.JS time cartesian (time.unit: second ) xAxes only shows 1 second difference in C#

I have 3 sets of data that have a timestamp (x) and value (y). I have tried to use guides and documentation to try to use the options scale xAxes type: “time” unit seconds. The graph shows nothing but y values on the y axes, labels and a 1 second difference on the x axes.
My code.
Basically, when i add the option to set the unit to seconds my chart breaks. I have no idea why.
Any suggestions would be helpful.

JavaScript – convert text from API response to JavaScript array

I’m receiving some text from an API with JavaScript.

I need to convert this text into a JavaScript array to use it. Currently I can get the text but I need an extra step to convert it into a JavaScript array so I can console.log() it.

// API response. Note there are no quotes around it, it is exactly as is below
//["hi ",["hi medicaid","hi mama","hi in french","hi in spanish","hi in japanese","hi there","hi mom","hi in chinese"],"search"]

const response = await fetch("/autocomplete.php", {
     method: "POST"
});

const data = await response.text();
        
// Breaks down here
console.log(data[1]); // This logs: "

Cash App Phone Number (I866꞊978꞊5841) Cash App Customer Service Number

Many of you might have received a call from cash app phone number +1-866-978-5841, or you might have seen the number on a financial transaction or a credit card statement. If you have seen this number, then you must know that is from the company Square. Square permits small businessmen to get credit cards with the help of mobile devices. The company also owns an app named Cash App that allows you to send money to your friends or family members by using mobile devices. Square allows small businessmen to process credit cards. As a result, you will see that the name of the company and the cash app customer service number +1-866-978-5841 will be found on a transaction. This might be because this transaction was done by a small business owner.

Logical grouping in HTML for results pulled from object

I am successfully iterating through an object/array from an API and am able to take three parameters, Author/Title/Description, and place results from each parameter into their own lists. In other words, all Authors from the array are being placed in html into one list, all Titles are placed into one list, all descriptions are placed into one list.

How can I group the results logically, as in, for each book have the results Author/Title/Desc placed into one area on the page …(div?)?

const searchButton = document.getElementById('searchbtn')
const form = document.getElementById('myform')
const author = document.querySelector('.author')
const title = document.querySelector('.title')
const description = document.querySelector('.description')

document.addEventListener("DOMContentLoaded", () => {
    searchButton.addEventListener('click', e => {
        e.preventDefault()
        const inputSearch = document.getElementById('books').value
        const bookUrl = ('https://www.googleapis.com/books/v1/volumes?q=' + inputSearch)
        fetch(bookUrl)
        .then (res => res.json())
        .then (obj => {
            obj.items.forEach((book, index) => {
                const listAuthor = document.createElement('li')
                const listTitle = document.createElement('li')
                const listDescription = document.createElement('li')
                listAuthor.innerText = book.volumeInfo.authors
                listTitle.innerText = book.volumeInfo.title
                listDescription.innerText = book.volumeInfo.description

                author.appendChild(listAuthor)
                title.appendChild(listTitle)
                description.appendChild(listDescription)
            })
            form.reset()
        })
    })
})

understanding border-images to fill perfectly without streching

I try to use an image as a border image for a div.

The div width and height changes (I don’t know how the dimensions will be)

The border-images width and height changes (I don’t know how the dimensions will be)

I really tried to understand what is slicing doing, but I can’t get a dynamic formula so that any given border-image will look good for any given div size (look good = not sctreched, filled,nicely repeated as long the border-image is seamless)

for a given border-image pineapple.png with a dimension 1584x1200px => 105 133 round looks good, but how do I get this magic numbers? What numbers use there for slice to get a crispy border-image regarding not violating its proportions? Is it depending on the div size AND the border-image size?

div{
background:red;
height:100px;
width:400px;
border: solid 5vmin transparent;
border-width: 5.67909vmin;
border-image: url(https://cdn.dribbble.com/users/4297010/screenshots/7740500/media/7c2554596ed3249419127182c5199e65.jpg)105 133 round;

Javascript solutions are also much appreciated

How to check the URL of a page using JavaScript

How would I make a script that detects the current URL of the page? Here is what I want it to do:

When the script is on example.com it lets the page load normally.

When the script is on coolsite.com it replaces the content of the page with a note showing a link to example.com

How would I do that? Is there a function that detects the location of the window? I can put it in a <script> element or a separate JavaScript file.

Thank you for any help!
