I have some hyperlinks.I want click the link in div1, then post the different value and show in div2. Click diffrent link, the div2 will change to display different value. I need all the post without refresh the page.

<div id="div1">
<ul>
<form method="POST" action="index.php">
<li>
<input type="text" name="name" id="name">
<a href="index.php">test1</a>
<input type="submit" name="sub" id="sub" value="test">
</li>
<li>
<input type="text" name="name" id="name">
<a href="index.php">test2</a>
<input type="submit" name="sub" id="sub" value="test2">
</li>
</form>
</ul>
</div>
<div id="div2">
this is a <? $_POST["name"]; ?>, just a test.
</div>

The code above is wrong, just show my page struction.
Can you give me a simple example? or some demos online? Thanks.
