Я украл AJAX из DataLife и доволен как слон - работает быстро и легко!

Я думаю, это не только мне время сэкономит.
PHP:

<script type="text/javascript">
function send(){
var frm = document.mybonus;
var bonus_type = '';
for (var i=0;i < frm.elements.length;i++) {
var elmnt = frm.elements[i];
if (elmnt.type=='radio') {
if(elmnt.checked == true){ bonus_type = elmnt.value; break;}
}
}
var ajax = new tbdev_ajax();
ajax.onShow ('');
var varsString = "";
ajax.requestFile = "mybonus.php";
ajax.setVar("id", bonus_type);
ajax.method = 'POST';
ajax.element = 'ajax';
ajax.sendAJAX(varsString);
}
</script>
