Jquery math addition -

-

i'm trying add through jquery event , i'm getting nan. missing?

   <input type="hidden" id="skillcount" name="skillcount" value="3" onchange="valueadd(this)"/>     function valueadd(ok){ var value=parsefloat($(this).val())+1; }

the code should be:

function valueadd(ok){   // "this" inside here refers window   var value=parsefloat(ok.value)+1; }

the inline onchange anonymous function:

function() {    //"this" inside here refers element    valueadd(this); }

so "this" argument gets called "ok" in valueadd scope. others have stated, though, want use jquery's bind "this" inside of valueadd point element.
