How to change tooltip color on open using jQuery UI Tooltip?

Question

I'm trying to achieve the following, can't figure out how though. I have several tooltips on a page, but I want each one to look different (depending on severity for instance). Here is what I have so far:

<div id="container">
<a href="#" title="Tooltip 1" data-severity="warning">Tooltip 1 (Warning)</a>
<a href="#" title="Tooltip 2" data-severity="danger">Tooltip 2 (Danger)</a>
</div>

<script type="text/javascript">
// init tooltip
ArrowToolTip.init('container');
</script>

/*JAVASCRIPT*/
var ArrowToolTip = {
init: function (parentId) {
    jQuery('#' + parentId).tooltip(
    {
        content: function () {
            var element = jQuery(this);
            return element.attr('title');
        },
        create: function () {
            var element = jQuery(this);

            var severity = element.data('severity');

            if (!severity) {
                severity = 'default';
            }

            element.tooltip('option', 'tooltipClass', severity);
        },
        open: function(event, ui) {
            var element = jQuery(this);
            var severity = element.data('severity');
            ui.tooltip({
                tooltipClass: severity 
            });
            //ui.tooltip.tooltipClass(severity);
            console.log(event);
            console.log(ui);
        }
    });
}
}

Whatever I have in the create: works, but it's only called on page load, so that doesn't do me any good. So now I'm trying to move this to the open: event. But that doesn't seem to work at all. The jQuery(this) doesn't return the hovered element, it returns the container. How can I get the correct element to select the data attribute? And how can I then change the CSS class? Does anyone know how this could be achieved?

I didn't get your logic very well, but here's how I achieve different classes depending on data-severity. Instead of applying .tooltip() to all elements, iterate through them and set the tooltipClass as $(this).data('severity'). The content function allows to add a class too.

$('a.tips').each(function () {
    var severity = $(this).data('severity');
    $(this).tooltip({
        content: function () {
            return '<em>' + $(this).attr('title') + '</em>';
        },
        tooltipClass: severity,
        show: "slideDown",
        open: function (event, ui) {
            ui.tooltip.hover(function () {
                $(this).fadeTo("slow", 0.5);
            });
        }
    });
});

.ui-tooltip {
    padding: 10px 20px;
    border-radius: 20px;
    font: bold 14px"Helvetica Neue", Sans-Serif;
    text-transform: uppercase;
    box-shadow: 0 0 7px black;
}
.ui-tooltip.warning {
    color: #E3E8F7;
    background: #D94AA4;
}
.ui-tooltip.danger {
    color: #212942;
    background: #CABA75;
}
a.tips { float:left; margin: 0 10px; text-decoration:none; font: Sans-Serif; }
body { background-color:#eee; padding: 30px; }
