Triggering click events from within a FF sandbox

I am trying to trigger a click event on an element on a page from within a Firefox sandbox. I have tried using jQuery's .click() as well as doing:

var evt = document.createEvent("HTMLEvents");
evt.initEvent("click", true, false );
toClick[0].dispatchEvent(evt);

Has anyone been able to trigger a click event on a page in the browser through a sandbox? I can get the DOM element fine, but triggering the event is a different story.

Solution

  • You have to create the event on the right document:

    var evt = pageDocument.createEvent("HTMLEvents");
evt.initEvent("click", true, false );
toClick[0].dispatchEvent(evt);

    The true means the event "bubbles" and the false means the event cannot be cancelled. From https://developer.mozilla.org/en/DOM/event.initEvent
