$("a[title]").each(function() {
var a = $(this);
var title = a.attr('title');
if (title == undefined || title == "") return;
a.data('title', title)
.removeAttr('title')
.hover(
function () {
var offset = a.offset();
$("<div id=\"anchortitlecontainer\"></div>").appendTo($("body")).html(title).css({ top: offset.top + a.outerHeight() + 10, left: offset.left + a.outerWidth() + 1 }).fadeIn(function () {
var pop = $(this);
setTimeout(function () { pop.remove(); }, pop.text().length*80);
});
},
function() { $("#anchortitlecontainer").remove(); }
);
