How can link text appear in a text box when clicked?

I have something like this:

<a href="blah.html">link text</a>
<input name="name">

And I want "link text" to appear in the input box when it is clicked. Is there any way to do this?

below is a small example...

<form>
<input type="text" name="link" />
<a href="#" onclick="document.forms[0].link.value ='link text';return false;">Link Text</a>
</form>

I am assuming that the link should not actually go to a new page or that would defeat the purpose. If I am barking up the wrong tree, let me know.
