JQuery UI 1.8.10 Cannot read property '3' of undefined

I use JQuery UI 1.8.10 and jquery latest.

My code is:

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.10/jquery-ui.js"></script>
<script type="text/javascript" src="/cms/ww.admin/login/login.js"></script>

<div id="header"></div>
        require SCRIPTBASE.'cms/ww.incs/login-codes.php';
        $login_msg = $_REQUEST['login_msg'];
            echo '<script>$(function(){$("<strong>'.htmlspecialchars($login_msg_codes[$login_msg]).'</strong>").dialog({modal:true});});</script>';


why does this give a cannot read property '3' of undefined error?

the file that gives the error is jquery-ui.js on line 186

okay now i changed it to:


<div id="header"></div>
<div id="login-msg"></div>
require SCRIPTBASE.'cms/ww.incs/login-codes.php';
   echo '<script>$(function(){

But still the same error


It's a bug from your jQueryUI which use a :data selector (if you go up in the call stack you will see it) which is deprecated/not compatible with latest jQuery. Try with this jQueryUI :


example here :


You found a bug/incompatibility!!

this isn't working jquery (1.8.0): http://jsfiddle.net/mZPWS/

Older jquery version (1.7.2) is working: http://jsfiddle.net/mZPWS/1/

It might not be the source of your problem, but maybe setting a div for your .dialog() widget can help you.

Your js line $("<strong>'.htmlspecialchars($login_msg_codes[$login_msg]).'</strong>").dialog({modal:true} seems to be using a simple message, which in most cases works.

Can you try changing using this line instead :

    $("#header") // or any div you have

also, make sure your "/cms/ww.admin/login/login.js" is not the source of the error, the js error console gets easily lost and can point you to jquery-ui.js while the error is somewhere else.

I confirm the uncompatibility issue. Tried with jquery-1.8.0 and jquery-ui-1.8.4
