To trim for extra white spaces before and after the string, you can use trim function of the jQuery.

<script type="text/javascript">
            var v = $.trim("         There are extra spacces before and after this sentences. ");
            alert(v);
    </script>

This will trim the extra white spaces before and after the sentence and alert the result string.

Hi Poster,

Thanks for this useful code. There is one more advantage of using trim that you can check element is empty or not. See below post.
