firefox add-on shortcut does not work anymore

问题:

I have used following commands in my browser.xul to set a shortcut for my addon.

<keyset id="mainKeyset">   <key id="key_convert"        modifiers="accel"        keycode="VK_F12"        oncommand="myfunction()" />" </keyset> 

It used to work for previous versions of Firefox, but not anymore for newer versions. has anything changed in the syntax?

Thanks

That code example looks correct, I suspect that there is some code within myfunction() that is failing, so we need more information probably. Try to replace myfunction() with alert("test"), that should work.

Some notes:

• You must add it to a keyset, as the key listeners are attached when keyset is added
  • source: http://forums.mozillazine.org/viewtopic.php?f=19&t=2711165&p=12885299&hilit=mainKeyset#p12885299
• You must set an oncommand attribute

Can copy paste this to scratchpad:

var keyset = document.createElementNS('http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'keyset'); //http://forums.mozillazine.org/viewtopic.php?f=19&t=2711165&p=12885299&hilit=mainKeyset#p12885299 //cant use mainKeyset see topic above var key = document.createElementNS('http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'key'); var props = {   id: 'key_convert',   modifiers: 'accel',   keycode: 'VK_F12',   oncommand: 'alert("tirggered")' }; for (var p in props) {   key.setAttribute(p, props[p]); } keyset.appendChild(key); Services.wm.getMostRecentWindow('navigator:browser').document.documentElement.appendChild(keyset);
