== JEP 108 - Background Page ==

* Bug Ticket: [https://bugzilla.mozilla.org/show_bug.cgi?id=546740 546740]

Background Pages are like a more open and free sandbox for doing most anything in a traditional web page with a DOM context, but with a key difference: the page is augmented with escalated, waterfall chrome privileges. It is essentially along the same line of a Web Worker, just more open and accessible.

* Dynamically generated code sent to the Background Page should be injected and executed in the Background Page's window context.

==== Background Page Global: <i>$dom</i> ====

==== Background Page Method: <i>run</i> ====

Allows you to run code in the DOM Worker's window context.

#<b><i>action</i></b> - (<i>function</i>) a function to be executed within the DOM of the Background Page - by default, the Background Page's window object is the bound 'this' within the function

$dom.run({ interval: 10000 }, function(){

==== Background Page Method: <i>empty</i> ====

Empties the DOM Worker's of all elements (this includes the body, which is then reinserted fresh).

The Background Page Global object: <i>$dom</i>

$dom.empty();

==== Background Page Method: <i>reset</i> ====

Resets the DOM Worker to a blank HTML page with no elements and a clean global window object.

No arguments are used in accordance with this method

The Background Page Global object: <i>$dom</i>

$dom.reset();
