Example 2 on http://docs.jquery.com/Events/trigger doesn't work. Here the example code:

$("p").click( function (event, a, b) {

when a normal click fires, a and b are undefined

for a trigger like below a refers too "foo" and b refers to "bar"

} ).trigger("click", ["foo", "bar"]);

I've done my own example for this (see Attachement).
