Javascript - Check if Object-Content has changed

Question

my solution

// calculate Hash from Object
var jsString = $.toJSON(jsObject); 
var jsString = jsString.length;
var jsStringHashNew = $.md5(jsString);

// my Check
if(jsStringHashOld != jsStringHashNew)
{
   alert('new content in Object');
}

But this i maybe a little bit dirty? Right?
Does anybody know a a better(faster) solution?

Thanks in advance!

Have a look at Underscore.js's isEqual. (search source for isEqual)
