The livequery "match/nomatch" events don't work with jQuery pseudoselectors like ":visible". They do work for class selectors.
An easy fix would be to also add a class when you show the item, and remove a class when you hide the item.
For example:
(html)
<input type="button" value="toggle"/>
<div id="item"
style="width:100px;height:100px;background-color:#ff0"
class="Visible">
</div>
(script)
$(function() {
$("#item.Visible").livequery(
function() {
alert("match");
},
function() {
alert("nomatch");
}
);
$("input").click(function() {
if ($("#item").is(":visible"))
$("#item").hide().removeClass("Visible");
else
$("#item").show().addClass("Visible");
});
});
