Some help needed

One of my team mate is encountering a problem. Actually he have a database with columns id and name. He have inserted the value manually and then retrieving the values using AJAX function. Below I am attaching the function using which he is retrieving data from the database.

<script type="text/javascript">
window.onload = showALL;
function showALL()
{
var xmlrqst;
if(window.XMLHttpRequest){
xmlrqst = new XMLHttpRequest();
}
else{
xmlrqst = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlrqst.onreadystatechange = function(){
if(xmlrqst.readyState==4 && xmlrqst.status==200)
{
document.getElementById("userall").innerHTML = xmlrqst.responseText;
}
}
xmlrqst.open("GET","post.php?get=1",true);
xmlrqst.send();
}// showAll()
</script>

the aforementioned javascript is in the index.php.
here you can see that i am using a post.php and is passing parameter through the url to post.php

below is the code that is being executed in the post.php

<?php
if(isset($_GET['get']))
{
if($_GET['get']!=1)
{
echo "error";
}
$showAll = "SELECT * FROM names";
$showAllQuery = mysql_query($showAll,$con);
if(!$showAllQuery){ die("error".mysql_error());}
echo "<table>";
echo "<th>ID</th>";
echo "<th>NAME</th>";
while($output=mysql_fetch_array($showAllQuery))
{
$out = $output['id'];
echo"<tr>";
echo "<td>{$output['id']}</td>";
echo "<td>{$output['name']}</td>";
echo "<td><a href=\"#\">delete</a></td>";
echo "</tr>";

}
echo "</table>";

}
?>

in the post.php he is generating the table with user data and it is being displayed in the index.php file in the <div ></div> section.

Now, lets discuss his problem. The problem is the data are generated in the post.php and is displayed in the index.php in a certain div. How can he delete value from database using AJAX?

Re: Some help needed

echo "<td><a href=\"#\">delete</a></td>";

instead use

echo "<td><a href=\"#\" onclick="return delete({$output['id']})">delete</a></td>";

then in javascript

function delete(id)

callAjax("delete.php?id="+id,result);

function result(data)

display message
