jQuery allowed?

Are we allowed to use jQuery? I would like to use it for ajax and for manipulating the HTML in real-time without having to reload the page so many times.

a sample of the kind of thing I would like to do there looks like this. This is part of the system I'm writing at work, this code is copyrighted so no copying it from me!

Language: Javascript
	<script type="text/javascript">
		//confirm not safe
		function checkForm() {
			if($(';input:radio[name=safe]:checked';).val() == ';no';) {
				return confirm("Are you sure this item is NOT safe to use?");
			}
		}
		$(document).ready(function(){
			var assetno = "";
			//get the info for the asset children and output
			$("#asset_num").bind("change", function(){
				assetno = $(';#asset_num option:selected';).text();
 
				$.post("./asset_child_info.php",{asset: assetno},function(data){
					var vals = new Array();
					var untrimed = new Array();
					untrimed = data.split(",");
 
					for(var i=0; i < untrimed.length; i++) {
						vals[i] = $.trim(untrimed[i]);
					}
					//output children
					$("#children").hide();
					$("#children").empty();
					var childrenList = "All these items have to be present:<br /><ol>";
					for(var i=0; i < vals.length; i++) {
						childrenList = childrenList + "<li>" + vals[i] + "</li>";
					}
					childrenList = childrenList + "</ol>";
					$("#children").append(childrenList);
					$("#children").fadeIn(';fast';);
 
				});
			});
		});//end main func
 
	</script>

The server side:

Language: PHP
<?php
include(';../../../bin/config/coninfo.php';);
$con = mysql_connect($server, $usrname, $pwd);
if(!$con) {
	die(';Could not connect: '; . mysql_error());
}
 
$asset = xssFilter($_POST[';asset';]);
$retstring = "";
 
mysql_select_db(';ndms_admin';, $con);
 
$query = "SELECT name FROM equipment_new 
			WHERE assetcode=';{$asset}';
			AND name!=';MAIN UNIT';";
 
$result = mysql_query($query);
 
while($row = mysql_fetch_array($result)) {
	$retstring .= $row[';name';] . ",";
}
 
//remove last comma
$retstring = substr_replace($retstring ,"",-1);
 
echo $retstring;

This gets the asset children from the database and displays them in a div without reloading the page. I would like to do something similar with the deleting a player section. I have some cool ideas there.

You can use jquery yes..... Just not php frameworks.

Awesome! Thanks, I promise, no php frameworks.
