From Which Frame alert occurs?
I have a page with six ifrmaes inside it. Each frame has individual id, so it is easy to detect the frame. All these frames have commono src. And each source I开发者_如何学JAVA set
window.onload=function(){
alert(' this has been alerted from Iframe with id#");
}
How can I know the ID of the frame from which the alert is alerting?
Thanks.
You can do it like this:
Frameset:
<html>
<body>
<iframe src="frame.html" id="frameID1" name="frameName1"></iframe>
<iframe src="frame.html" id="frameID2" name="frameName2"></iframe>
<iframe src="frame.html" id="frameID3" name="frameName3"></iframe>
<iframe src="frame.html" id="frameID4" name="frameName4"></iframe>
<iframe src="frame.html" id="frameID5" name="frameName5"></iframe>
<iframe src="frame.html" id="frameID6" name="frameName6"></iframe>
</body>
</html>
Frame:
<html>
<head>
<script type="text/javascript">
window.onload=function() {
alert('This has been alerted from frame with id#: ' + GetFrameID(this.name));
}
function GetFrameID(frameName) {
var frames = top.document.getElementsByTagName('iframe');
if (frames != null) {
for (var i = 0; i < frames.length; i++) {
if (frames[i].name == frameName) return frames[i].id;
}
}
return null;
}
</script>
</head>
<body>
</body>
</html>
