Read contents of an Iframe

In the parent page:

<script type="text/javascript">
<!--
function get_contents(){
iframe_div=window.frames["iframe1_name"].document.body.innerHTML
document.getElementById("div_id").innerHTML=iframe_div
}
// -->
</script>

<iframe name="iframe_name" width="300" height="100" src="page.htm"></iframe>

<div id="div_id"></div>

<a href="#null" onclick="get_contents()">Get Contents</a>

If you are wanting to reference a specific element in the Iframe page use the following line in the function above

iframe_div=window.frames["iframe1_name"].document.getElementById("display").innerHTML

and put

<div id="display">Your Contents</div>

in the iframe page

You could also call the function in the parent page from the Iframe page by including

<script type="text/javascript">
<!--
function send_contents(){
parent.get_contents()
}

//Include onload="send_contents()" in the opening BODY tag

// -->
</script>
