Detecting Unsaved Changes

by

Using jQuery:

var _isDirty = false;
$("input[type="text"]").change(function(){
  _isDirty = true;
});
// replicate for other input types and selects

Combine with onunload/onbeforeunload methods as required.

From the comments, the following references all input fields, without duplicating code:

$(':input').change(function () {

Using $(":input") refers to all input, textarea, select, and button elements.
