Question

I was disabling a hiperlink using this function, but i don’t really understand what really the function does, my doubt is the next one, i have this function:

function bindPrevent(e)
 {
    e.preventDefault();
    return false;
 }

and when the user clicks the link i do this:

function disableButton(f)
{
     if(f)
     {
    $('.btnOk[id!="link_lkDelete"]').each(function(){
            $(this).bind("click",bindPrevent);
        });
     }
     else
     {
    $('.btnOk[id!="link_lkDelete"]').each(function(){
            $(this).unbind("click",bindPrevent);

        });
      }
 }

The question is, if the link has another click handler, and i bind a new one, then which handler is called??, JQ use something like a handler stack and executes the top one handler??

Answer 1

Like others have stated, both handlers will be called. Here’s a fiddle illustrating it.
