Jquery Callback Without Anonymous Function

/ Published in: JavaScript
Save to your folder(s)
Is very inefficient to attach a anonymous function event handlers to multiple items in a selection. The function is duplicated for each element.

This shows how you can just create a single function and in the event handler callback just call that function.

  6.    e.preventDefault();
  7.    //this - is the element this func is attached to
  8.    alert($(this).attr('href');
