hi gays
i need to show some local file instead original url when user dont set font
size of current page.
so i need to change tab url by:
var myExt_urlBarListener = {
QueryInterface: function(aIID)
{
if (aIID.equals(Components.interfaces.nsIWebProgressListener) ||
aIID.equals(Components.interfaces.nsISupportsWeakReference) ||
aIID.equals(Components.interfaces.nsISupports))
return this;
throw Components.results.NS_NOINTERFACE;
},
onLocationChange: function(aProgress, aRequest, aURI)
{
myExtension.processNewURL(aURI);
},
onStateChange: function() {},
onProgressChange: function() {},
onStatusChange: function() {},
onSecurityChange: function() {},
onLinkIconAvailable: function() {}
};
var myExtension = {
oldURL: null,
init: function() {
// Listen for webpage loads
gBrowser.addProgressListener(myExt_urlBarListener,
Components.interfaces.nsIWebProgress.NOTIFY_STATE_DOCUMENT);
},
uninit: function() {
gBrowser.removeProgressListener(myExt_urlBarListener);
},
processNewURL: function(aURI) {
if (aURI.spec == this.oldURL)
return;
// now we know the url is new...
alert(aURI.spec);
this.oldURL = aURI.spec;
}
};
window.addEventListener("load", function() {myExtension.init()}, false);
window.addEventListener("unload", function() {myExtension.uninit()}, false);
any body can help me?
is it possible to change tab url directly or i must find tab index first and
then change it ?
