Use $.get() to perform ajax get

jQuery

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>

$(document).ready(function(){
    $('a[href="page.php?value=3"]').click(function(e){
        e.preventDefault()
        $.get("page.php",{value:3},function(data){
           alert(data);
        });
    });
});

</script>
<a href="page.php?value=3">Go</a>

page.php

<?php
 $getValue = $_GET['value'];
 echo $getValue;
?>

1. Include jQuery library.
2. Wrap your code within $(document).ready(function(){ }) handler, in order to bind even after dom element is loaded.
3. Use preventDefault() method to prevent browser default action on the event.
4. Use click() for listening click event.
5. At last use $.get() for Ajax get.
