What does "e" mean in this function definition?

Question

Can I pass an additional parameter to this function?

$("#foold").click( function(e) {
  // CODE
};

For example, I need to pass some X value to this function. Can I write something like this:

<a href="javascript:void(X)" id="fooId">Foo</a>

to pass value in this function through e or some other way?

No. e in that context is the event object that is populated when the event callback is executed. What are you trying to do? — Austin Brunkhorst, Mar 14 '12 at 15:46

Here, e is an event object, as defined here: http://api.jquery.com/category/events/event-object/

Yes you can pass data to the handler, using this form for the click function:

.click( [eventData], handler(eventObject) )

eventData             A map of data that will be passed to the event handler.
handler(eventObject)  A function to execute each time the event is triggered.

It will be accessible as e.data in the handler.

In this link you can see how to pass params to the JQuery click function jQuery's .click - pass parameters to user function

Basically

It allows you to pass a data map to the event object that automatically gets fed back to the event handler function by jQuery as the first parameter.
