How do you get the length of a string?

Question

You don't need jquery, just use yourstring.length. See reference here and also here.

Update:

To support unicode strings, length need to be computed as following:

[..."𠮷"].length

or create an auxiliary function

function uniLen(s) {
    return [...s].length
}

The easiest way:

$('#selector').val().length

jQuery is a JavaScript library.

You don't need to use jQuery to get the length of a string because it is a basic JavaScript string object property.

somestring.length;

HTML

<div class="selector">Text mates</div>

SCRIPT

alert(jQuery('.selector').text().length);

RESULT

10

You don't need to use jquery.

var myString = 'abc';
var n = myString.length;

n will be 3.

A somewhat important distinction is if the element is an input or not. If an input you can use:

$('#selector').val().length;

otherwise if the element is a different html element like a paragraph or list item div etc, you must use

$('#selector').text().length;
