That is FAR superior to the validationengine pop ups!!!!
May I suggest that this would be a VERY nice option when building the component - give the developer the choice of using the information text in the JS pop or in Joomla tooltips.
Here's what I added to my XML. Not sure if it's common knowledge or not, but I found the "labelclass" info at
joomlacode.org/gf/project/joomla/tracker...racker_item_id=28450. I just changed
info-msg to
description (per your suggestion) .
labelclass="mytooltip"
description="This is the description that appears in the tooltip"
Then, added some css to have a nice little tooltip info image appear to the left of my title:
label.tooltip {
background-image: url("components/my_component/images/icon-16-info.png");
position:absolute;
padding-left:20px;
background-position: 0 3px;
background-repeat: no-repeat;
}
