How do you get the length of a string?

Question

How do you get the length of a string in jQuery?

Answer 1

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

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

same way you do it in javascript:

"something".length

Answer 4

The easiest way:

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

Answer 5

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

alert(str.length);

Answer 6

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;
