Question

I have a page that displays an error div with a class of ‘validation-errors‘ if the user enters an incorrect value into a textbox.

Is there a way to execute a javascript function (it adds a CSS property to a button) when the error div is displayed? The function is currently called in window.onload.

Is there a way to execute the javascript function if window has changed / element added?

Answer 1

$('.validation-errors').bind('DOMSubtreeModified', function () {
  if ($('.validation-errors').length) { 
    // code
  }
});
