I am a noob and attempting to retrieve a HTML list from an Iframe

  • 0

I am a noob and attempting to retrieve a HTML list from an Iframe and update a list within the parent frame from the push of a button within the parent frame.
Please help, i keep retrieving an error ‘UpdateList is not defined’, I know i must be doing something wrong, currently feel like banging my head on a wall and plead for assistance 

<html> 
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<style>

<script type="text/Javascript">
function UpdateList(){
var OldList = document.getElementById('Framed');
var Newlist = OldList.contentWindow;
document.getElementById('FileList').innerHTML= Newlist;}


</script>

</style>
</head>
<body style="color:white">
<div id="FileList">
<select>
<option>Push Refresh</option>
</select>
</div>
<iframe NAME="Framed" id="Framed" src="DirectoryPreview.php" width="250" height="100">
</iframe>
<br>
<button onclick="UpdateList()">Push to refresh</button>
</body>


           **Correction for the above, hope it helps others struggling**

    Your javascript is embedded inside style tag!!!!How can you ever expect it to execute???

    Change it:-

    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
<style>
</style> 

<script type="text/Javascript">
function UpdateList(){
var OldList = document.getElementById("Framed");
var Newlist = OldList.contentWindow;
document.getElementById("FileList").innerHTML= Newlist;
}
</script>
