open link in iframe [closed]
Assuming the iFrame has a name attribute of "myIframe":
<a href="http://www.google.com" target="myIframe">Link Text</a>
You can also accomplish this with the use of Javascript. The iFrame has a src attribute which specifies the location it shows. As such, it's a simple matter of binding the click of a link to changing that src attribute.
Try this:
<iframe name="iframe1" src="target.html"></iframe>
<a href="link.html" target="iframe1">link</a>
The "target" attribute should open in the iframe.
