Adding rules JQuery validation not working in IE

Question

I'm adding JQuery validation rules dinamically with the function below:

function addRules(rulesObj) {
    for (item in rulesObj) {
        $('#' + item).rules('add', rulesObj[item]);
    }
}

I'm using JQuery version 1.7.2 and JQuery validate 1.9 and it is not working in IE 7 and 8. Works fine in Chrome and FF. Am I missing anything? The error: Object doesn't support this action.

The rule looks like this:

var ctrxRules = {
        L4 : {
            required : true
             }
};

If the rule is empty it works.

I tried replicating this, but wasn't successful. Would you mind providing an example on fiddle.net that demonstrates this? — Sampson

I understand, however I'm curious how it solved the problem. Can you please provide an example of your faulty code via fiddle.net, so that we can better document the issue? As @Ryley said, he was unable to actually explain the reason why the code worked. — Sampson

Well everything is on my computer at work. I didn't use any script debugger on IE but when I commented the addRules function or commented the body the page loaded. There is not much more I can say, I've stated the versions of JQuery, JQuery validate and IE — Samson

I can't explain why, but the solution is simple, add a var before item:

function addRules(rulesObj) {
    for (var item in rulesObj) {
        $('#' + item).rules('add', rulesObj[item]);
    }
}

It's probably because declaring the variable without keyword 'var' pollutes the global scope with the 'item'
