Reset to default 4

Firefox only has a click() function for form elements such as buttons. However, you can call the onClick function directly; you can change the line to 

document.getElementById('mylabel').onclick();

This works in firefox or IE (but note that it requires that the function actually exists, which you know it does in this example).

Also note that you aren't actually simulating a click on that element (so, for example, if there were other things that such a click would do, such as also act as a click on the container, they won't happen). You're just getting the function that would run on a click, and running it directly. So it's not a solution for all situations where you need to simulate a click.

There's no click method on elements. Are you using any library?

Usually you have to do something like element.fireEvent('click') (prototype, mootools)

or element.click() (jquery)

UPDATE- Similar question: How do I programmatically click on an element in JavaScript?

Looks like an ugly and brittle solution, if I were you I'd just include jQuery and let that handle all the browser quirks.

Because the <p> tag does not have the method click.
