I am encountering a very annoying problem with IE. Basically I need to set the source of an IFrame using JavaScript, however the source document is being executed twice not once during each call.
The simplified HTML code is pasted below (I simplified it so that readers can understand it quickly. The source is being set through JavaScript since it will contain dynamic content):
<html>
<head>
<title>Iframe test</title>
</head>
<body>
<iframe id="testIframe" scrolling="no" frameborder="0" src="" width="800" height="600"></iframe>
<script language="JavaScript">
document.getElementById("testIframe").src = "http://localhost/test.php";
</script>
</body>
</html>
In this example, test.php inserts a record inside a local database once called. Whenever the page above is called using IE, two rows are being inserted on most occasions (sometimes only 1 row is inserted but this is not the norm). I tested the same script on Chrome and Opera and it works correctly on them so this must be an IE issue.
If is set the src directly inside the iframe tag IE starts behaving correctly, however I need to be able to build the URL using javascript.
Has anyone encountered this issue? and does anyone know of a solution/workaround?
Thanks and Regards Pierre

I managed to solve the issue. Basically I am now using
window.frames['testIframe'].document.location.href
instead of
document.getElementById("testIframe").src
and the source document is being hit only once.
