I have an IFrame in a page and IFrame has some JavaScript. At run time JavaScript in IFrame gives exception which i want to catch on parent window. How to do that?
<html>
<head>
<script type="text/javascript">
var frm123 = document.getElementById("frm123");
frm123.contentWindow.onerror = function() {
alert('error caught');
}
function loadData() {
var oRTE = document.getElementById("frm123").contentWindow.document;
oRTE.open();
oRTE.write(txt123.value);
oRTE.close();
}
</script>
</head>
<body>
<input type="button" onclick="loadData();" value="load">
<input type="text" id="txt123">
<iframe id = "frm123" >
</body>
</html>
