Question

I have a textarea with a default value of http://. Now when an user pastes in an url (if they don’t know what they are doing, like most people) it comes out like this http://http://www.google.com. I’ve seen a site that as soon as you have http://http:// it removes one via JavaScript.

I am not familiar with JavaScript, so can anyone help me?

I don’t want to clear the field on focus only.

You do not need ajax to do that just simple javascript can do the trick.

jQuery(document).ready(function(){

    jQuery('#idofurtextfield').blur(function(){

        jQuery(this).val(jQuery(this).val().replace(/(http:\/\/)\1/, '$1'));

    });

});
