jQuery remove spaces on blur not working

Question

The replace function I'm using works as I've tested it in the console but it does not work at all on blur. How can I fix that?

<script type="text/javascript">
    //Ensure spaces are not entered between tags
    jQuery(document).ready(function(){
        jQuery('#item_keywords').blur(function(){
            $(this).val().replace(/^\s+$/,"");
        });
    });
</script>

Answer 1

you have removed the spaces but u have not assigned them any where :)

jQuery(document).ready(function(){
        jQuery('#item_keywords').unbind('blur').bind('blur',function(){
            $(this).val($(this).val().replace(/^\s+$/,""));
        });
    });

Answer 2

I'm using:

        jQuery(document).ready(function(){
            jQuery('#business_email').unbind('blur').bind('blur',function(){
                var a = $(this).val().trim();
                $(this).val(a + '.');
                $(this).val(a);
            });
        });

You can try this.

$(document).ready(function(){
    $("#mytextbox").blur(function(){
        $(this).val($(this).val().replace(/\s/g,''));
        console.log($(this).val());
    });
});
