code sniplet:
create a panel like this:
<wicket:head>
<script type="text/javascript">
function showProgress()
{
! do the stuff here!
}
</script>
</wicket:head>
</head>
add the panel to your page(the javascript will be appended in head).
created a attributemodifier:
public class ProgressAttributeModifier extends AttributeAppender {
public ProgressAttributeModifier() {
super("onclick", true, new Model("showProgress()"), ";");
}
}
add that to your componet, this is a nice way of doing it I think.
