Difference between .click() and actually clicking a button? (javascript/jQuery)

Question

I\'m trying to figure out this weird issue I\'ve been having, and the root cause is the difference between a live click and triggering .click()

Answer 1

I use this function to truly mimic a mouse click:

function clickLink(link) {
    var cancelled = false;

    if (document.createEvent) {
        var event = document.createEvent("MouseEvents");
        event.initMouseEvent("click", true, true, window,
            0, 0, 0, 0, 0,
            false, false, false, false,
            0, null);
        cancelled = !link.dispatchEvent(event);
    }
    else if (link.fireEvent) {
        cancelled = !link.fireEvent("onclick");
    }
}
