Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).
You need to do a deep equals.
From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.
Object.extend(Object, {
deepEquals: function(o1, o2) {
var k1 = Object.keys(o1).sort();
var k2 = Object.keys(o2).sort();
if (k1.length != k2.length) return false;
return k1.zip(k2, function(keyPair) {
if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
} else {
return o1[keyPair[0]] == o2[keyPair[1]];
}
}).all();
}
});
Usage:
var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);
if (Object.deepEquals(anObj, anotherObj))
