Hiya,

I have a page set up as below, and I'm trying trigger the 'sayMessage' javascript function from a link in the page within the iframe (page.html).

Is this possible?

Thanks.

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>Test</title>

 

<script type="text/javascript">

function sayMessage(text) {

  alert(text);

}

</script>

</head>

 

<body>

 

<iframe name="iframe1" id="iframe1" frameborder="0" width="270" height="200" scrolling="no" src="page.html"></iframe>

 

</body>

</html>

This site has a tutorial about what you are trying to do.

I think that both parent and Iframe page need to be in the same domain/site.
<!-- Parent Code -->

<script language="Javascript">

function testIframe() {

 alert('Called from Iframe!'); 

}

</script>
 

<iframe src="testIframe.html"></iframe>
 
 

<!-- IFRAME CODE -->

<script language="Javascript">

  parent.testIframe();

</script>

Only if both pages are from your own domain. Otherwise it would be cross-site scripting, and the browser would NOT allow it. To call your function from the iframe you can use:
<a onclick="top.sayMessage('Hi');"...>...</a>
