Detecting data changes in forms using jQuery

Question

I\'m using ASP.NET 2.0 with a Master Page, and I was wondering if anyone knew of a way to detect when the fields within a certain

or fieldset<

Answer 1

You could bind the Change event for all inputs and flag a variable as true. Like this.

var somethingChanged = false;
$(document).ready(function() { 
   $('input').change(function() { 
        somethingChanged = true; 
   }); 
});

But, keep in mind that if the user changes something, then changes back to the original values, it will still be flagged as changed.

UPDATE: For a specific div or fieldset. Just use the id for the given fieldset or div. Example:

var somethingChanged = false;
$(document).ready(function() { 
   $('#myDiv input').change(function() { 
        somethingChanged = true; 
   }); 
});
