HTML DOM contentDocument Property

Complete Frame Object Reference

Definition and Usage

The contentDocument property returns the document the frame contains as an HTML object.

The returned object can be processed with all standard DOM methods.

Syntax

frameObject.contentDocument

Example

In our example we will first create an HTML document containing a frameset with two columns. Each column is set to 50% of the browser window:

<html>
  <frameset cols="50%,50%">
    <frame id="leftFrame" src="frame_cdoc.htm">
    <frame id="rightFrame" src="frame_a.htm">
  </frameset>
</html>

The HTML document "frame_cdoc.htm" is put into the first column, and the HTML document "frame_a.htm" is put into the second column.

The source of "frame_cdoc.htm" is as follows:

<html>
<head>
<script type="text/javascript">
function showCDoc()
  {
  var x=parent.document.getElementById("leftFrame")
  alert(x.contentDocument.documentElement.tagName)
  }
</script>
</head>
<body>

<input type="button" onclick="showCDoc()"
value="Show content-document's first tag" />

</body>
</html>
