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 });

The order of the numbers in my box is as follows:
function boxNumbers(){
let boxes = document.querySelectorAll('.box')
boxes.forEach((box,i)=>{
if(String(i).length==1 || (String(i).length==2 && Number(String(i)[0]))%2==0){
//box.innerHTML = `${100-i}, i=${i}`
box.innerHTML = 100-i
}
else{
box.innerHTML = String(Number(`${9-Number(String(i)[0])}${String(i)[1]}`)+ 1)
}
})
}

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.
}
});

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) {});

I have been wondering if I can print a string with each letter having a different color.
If I can do this can anybody tell me how ?
You can't directly set the color (or any part of the style) of a letter, you have first to wrap it in its own element so that you can style it. Here's an example :
var e = document.getElementById('s');
e.innerHTML = e.innerHTML.split('').map(function(l){
return '<span style="color:#'
+Math.floor(Math.random()*16777216).toString(16)
+'">'+l+'<span>'
}).join('');
