[jQuery] Responding to a source change in an iframe

[jQuery] Responding to a source change in an iframe


Hello,
I am having trouble figuring out how to respond to a source change in
an iframe. In other words, if I have a iframe:
<iframe name="frame" frameborder="0" height="400px" width="500px"
src="http://www.google.com"></iframe>
And a link:
<a href="http://www.yahoo.com" target="frame">Change page</a>
I would like to have the iframe react when the source changes. I have
tried change() and contents() without any luck. Anyone have
suggestions? Thanks.
