Hi,
The following code, which build an array of all <input/> elements on a page,
works at every website I've tried except
https://banking.ing-diba.de/OnlineBanking/index.html.
Would someone be able to have a look? I cannot figure out why.
Context is browser.xul scope with
https://banking.ing-diba.de/OnlineBanking/index.html loaded:
var recentWindow = Components.classes["@mozilla.org/appshell/window-mediator;1"]
.getService(Components.interfaces.nsIWindowMediator)
.getMostRecentWindow("navigator:browser");
Ok, this looks like some dialog window so why don't you pass on the
window used to open the dialog, because that saves you the above lines.
if (recentWindow) {
doc = recentWindow.content.document;
// Build an array of all <input/> elements
// in the doc (including frames)
var inputFields = new Array();
// Check doc
var fields = doc.getElementsByTagName("input");
for (var i=0; i<fields.length; i++)
inputFields.push(fields[i]);
// Check frames
var frames = doc.getElementsByTagName("frame");
for (var i=0; i<frames.length; i++) {
fields = frames[i].contentDocument.getElementsByTagName("input");
for (var j=0; j<fields.length; j++)
inputFields.push(fields[j]);
}
// Check iframes
var frames = doc.getElementsByTagName("iframe");
for (var i=0; i<frames.length; i++) {
fields = frames[i].contentDocument.getElementsByTagName("input");
for (var j=0; j<fields.length; j++)
inputFields.push(fields[j]);
}
Why this difficult? I mean, all frames end up in content.frames so why
don't you use that instead?
I hate code duplication so I would use something like this:
getInputFields(aWindow)
{
var inputFields = new Array();
var frames = (aWindow.frames.length) ? aWindow.frames : aWindow.document;
function _getInputFields(aFrame)
{
var inputElements = aFrames.contentDocument.getElementsByName('input');
for (var i = 0; i < inputElements.length; i++) {
inputFields.push(inputElements[i]);
}
}
for (var fIndex = 0; fIndex < frames.length; fIndex++) {
if (!frames[fIndex].length) {
_getInputFields(frames[fIndex]);
} else {
frames.push(frames[iFrame]);
}
}
return inputFields;
}
Note: the above lines are nothing more than some quick untested JS code
snipped, but it should give some "how to" clues (at least I hope).
