How to find the number of characters in a string using jQuery

Topic: JavaScript / jQueryPrev|Next

Answer: Use the jQuery .length property

The jQuery .length property can be used to get or find out the number of characters in a string. You can also use this property to calculate the number of elements in a jQuery object.

Let's take a look at an example to understand how it basically works:

<script>
    $(document).ready(function(){
        var myStr = "      Paragraph of text with   multiple white     spaces before and after.       ";
        myStr.length; // Returns 81
        $.trim(myStr).length; // Returns 68
        myStr.replace(/ /g,'').length; // Returns 53
    });
</script>
