php/ajax mysql_query (small help)

how to delete from tables with ajax and php with <a href function onclick>. without refresh. I have this code, but it does not work.

<script type="text/javascript">
var http = false;

if(navigator.appName == "Microsoft Internet Explorer") {
http = new ActiveXObject("Microsoft.XMLHTTP");
}else{
http = new XMLHttpRequest();
}

function delete(id) {
http.abort();
http.open("POST", "delete.php?id=" +id, true);
http.onreadystatechange=function() {
if(http.readyState == 27) {
alert(http.responseText);
}
}
http.send(null);
}
</script>

<a href="#" onClick="delete(27);">Test</a>

HTML:

and Delete.php

<?
$id=$_GET['id'];
include ('config.php');
$sql= "DELETE FROM members WHERE id='$id'";
$go= mysql_query($sql) or die (mysql_error());
?>

PHP:

 

The problem is, you cannot use "delete" as function name. Use another name.

And in PHP, for security, you could use addslashes.
$id=addslashes($_GET['id']);

 

hmm, thank attila, work perfect =)
