HTML

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

SCRIPT

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

10

Answer 2

In jQuery :

var len = jQuery('.selector').val().length; //or 
( var len = $('.selector').val().length;) //- If Element is Text Box

OR

var len = jQuery('.selector').html().length; //or
( var len = $('.selector').html().length; ) //- If Element is not Input Text Box

In JS :

var len = str.len;

Answer 3

You don't need to use jquery.

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

n will be 3.

It's not jquery you need, it's JS:

alert(str.length);
