To pass the additional parameter to the event function pass an array of key value, as the second parameter to the bind event
bind('click', { message: time }, onClick);
e.g
{ message: time }
and access it in the function
using event<function parameter>.data.message<key>
<div id="div1" style="border: 1px solid black; width: 100px; height: 100px">
click me
</div>
<script type="text/javascript">
function onClick(event)
{
alert(event.data.message);
}
var time = "loaded at:" + new Date().toString();
$("div.#div1").bind('click', { message: time }, onClick);
</script>
