event.preventDefault() function not working in IE

Question

Following is my JavaScript (mootools) code:

$(\'orderNowForm\').addEvent(\'submit\', function (event) {
    event.prev         


        

Answer 1

preventDefault is a widespread standard; using an adhoc every time you want to be compliant with old IE versions is cumbersome, better to use a polyfill:

if (typeof Event.prototype.preventDefault === 'undefined') {
    Event.prototype.preventDefault = function (e, callback) {
        this.returnValue = false;
    };
}

This will modify the prototype of the Event and add this function, a great feature of javascript/DOM in general. Now you can use e.preventDefault with no problem.
