What is the argument for?

Question

$(document).ready(function(){
  $('#something ul a').click(function(e) {
   ...
   ...
    e.preventDefault();
  })
});

what is the e for and the e.preventDefault mean so i can understand what is happening here

Answer 1

The e argument is the event object.
It contains information about the click event.

For more information, see the documentation.

---

The preventDefault() method prevents the borwser's default action for the event.
In this case, it will prevent the browser from navigating to the link.

Answer 2

e is the event object, and prevent default is one of its functions.

Answer 3

It's preventing the default action of the event, e.g. going to the URL, or scrolling the page to the #location in the href.

The first argument to any event handler in jQuery is the event object itself.

Answer 4

E is event and preventDefaults prevents browser from performing a standard operation in response to such an event. For instance if this is a click event on a link, preventDefaults whould prevent browser from redirecting to a linked page.
