Well blank() was not created in jQuery.
You can create a new function for jQuery like this.
(function($){
$.fn.blank = function(){
return $.trim(this[0]).length == 0;
}
})(jQuery)
<input id="one" value="sadf" />
<input id="two" value=" " />
$('#one').blank(); // return false
$('#two').blank(); // return true
haven't tested the code but should be pointing you to the right
direction.
Great thing is that jQuery allows you to extend it as you see fit.
