I have some code for firefox that runs to check whether an element on the page exists with a certain event handler, in this case onclick. Ever since FF4 came out I've been getting NS_ERROR_NOT_AVAILABLE and I'm guessing it has to do with the XPCNativeWrapper around the elements. Here is the code I use :
var elem = null;
var elems = doc.getElementsByTagName('td');
var firefoxWindow = window;
for (a = 0; a < elems.length; a++) {
if (((elems[a] != null && elems[a].hasAttributes() == true && elems[a].getAttribute('onclick') != null && elems[a].getAttribute('onclick').toString().match(/Goodbye Wonderful/gim) != null && elems[a].getAttribute('onclick').toString().match(/Goodbye Wonderful/gim).length >= 0) || (elems[a] != null && elems[a].onclick != null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim) != null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim).length >= 0))) elem = elems[a];
}
var found = false;
var window = null;
for (var i = 0; i < firefoxWindow.frames.length; i++) {
if (firefoxWindow.frames[i].toString().toLowerCase().indexOf('object window') > -1) {
window = firefoxWindow.frames[i];
break;
}
}
function recursiveSearch(frames) {
for (var i = 0; i < frames.length; i++) {
var elems = frames[i].document.getElementsByTagName('td');
for (a = 0; a < elems.length; a++) {
if (((elems[a] != null && elems[a].hasAttributes() == true && elems[a].getAttribute('onclick') != null && elems[a].getAttribute('onclick').toString().match(/Goodbye Wonderful/gim) != null && elems[a].getAttribute('onclick').toString().match(/Goodbye Wonderful/gim).length >= 0) || (elems[a] != null && elems[a].onclick != null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim) != null && elems[a].onclick.toString().match(/Goodbye Wonderful/gim).length >= 0))) elem = elems[a];
}
if (elem) {
found = true;
return;
} else {
if (frames[i].frames.length > 0) {
recursiveSearch(frames[i].frames);
}
}
}
}
if (!elem && window.frames.length > 0) {
recursiveSearch(window.frames);
}
if (elem != null) {
print('##Result##' + elem.tagName);
} else {
print('failed');
I apologize for the long line in the middle but it does well to make sure that there are no null references. I have not been able to find anything on the changes made to events as this works just fine in FF 3.6. I have found that assigning events is different, but no mention of reading event properties.
