javascript - How to pass the id of an element that triggers an `onclick` event to the event handling function

Question

How do I pass the id of an element that triggers an onclick event to the event handling function.

I am doing something like this-

<link onclick="doWithThisElement(id_of_this_element)" />

Answer 1

Instead of passing the ID, you can just pass the element itself:

<link onclick="doWithThisElement(this)" />

Or, if you insist on passing the ID:

<link id="foo" onclick="doWithThisElement(this.id)" />
