Firefox Addon: Load URI Event

In a Firefox Addon I delegate the User to a new URL through

window.content.wrappedJSObject.location = 'http://newlocation/';

What I am 开发者_如何学运维asking for is a load event binding for the site-change. I tried

window.content.addEventListener('load', function() { });

.. which won't work.


Does this example cover what you want: On page load ?

If not, you have to specify further what you mean.


Make sure you actually look at the error messages. Ctrl-shift-J is your friend! In this case addEventListener requires a 3rd boolean parameter: window.content.addEventListener('load', function() { }, true); or window.content.addEventListener('load', function() { }, false);. This indicates whether you want the listener to be called during the bubbling phase or the capture phase. In most cases, it doesn't matter which one you use, except (IIRC) the load event doesn't bubble so you have to use the capturing phase (true).
