I know there are tonnes of answers to this question and all the answers are the same. I want to pass a variable to a selector. For example
var item = 'size_{{$item->size}}';
$("input[name="+item+"]").change(function () {
console.log('got it');
});
Let's say
{{$item->size}} == M // So the var item ='size_M'
This far the code is doing OK. There is no problem in item variable. But in the selector instead of getting size_M it's getting the item string itself.
actually i have to make this dynamic there may be lots of sizes like size_M,size_xxl, size_S and so on
in that case all you need is
https://api.jquery.com/attribute-starts-with-selector/
$( "input[name^='size_']" ).change(function () {
console.log('got it');
});

So I’m trying to check names through an array and I don’t want to have to use
if (<array name>[0,1,2,3,4,5,6,7])
{ code in here }
depend on what you are trying to do u can use forEach or map
let arr = [1,2,3,4,5,6,7,8,9,10];
arr.forEach((item)=>{
console.log(`${item} is greater than 5 : ${item>5}`)
})

If the input contains a whitespace, add classList 'invalid', otherwise remove it.
function idValidationAttacher() {
const id = document.querySelector('#newid');
id.addEventListener('input', id.classList.toggle('invalid', ));
}
const id = document.getElementById('newid');
id.addEventListener("input", () => {
if(id.value.includes(" ")) {
// Add the code to show the error here.
}
});

How to Display each variable of for loop in a div tag using javascript? Using innerHTML i am only able to display the last variable of for loop
You can do as follows, but it is better to use lists.
Lists: https://developer.mozilla.org/pt-BR/docs/Web/HTML/Element/ul
const myDreams = ["Fly", "Be rich", "Go to the moon"];
const myDreamsDiv = document.querySelector("#myDreams");
//The secret here is to add a breakline(<br>) between each word.
myDreams.forEach(dream => myDreamsDiv.innerHTML += (dream + "<br>"));
<div id="myDreams"></div>

I need to find an element that's text value is 0.
I do:
var d = $('.content').find('div');
if(d.text().length === 0){
//do something
}
Is there a way to put the above logic in the selector?
I've tried:
var d = $('.content').find('div:empty');
But no luck as the div may have other empty html tags in.
Use a filter
var elems = $('.content').find('div').filter(function() { return $(this).text() == 0 });

I need some help. See if you can help me out.
I have a function whose form is:
$this.find(settings.selector).each(function(index) {
Anyway, depending on a variable can change the selector as follows:
$this.each(function(index) {
Can you give me some idea how to do it? I hope I have explained roughly.
Thank you.
You can use a temp variable like
var $els;
if (some_condition) {
$els = $this.find(settings.selector)
} else {
$els = $this;
}
$els.each(function (index) {});
