Question

I am creating a web application and I want to use the Tabs widget to
replicate the tab functionality you find in most web browsers. I want
the user to be able: to move (sort) the tabs around, create tabs
dynamically, close tabs dynamically.

The problem I find is that to close a tab you need to have its index
and when considering the fact that other tabs can be opened, closed,
and sorted dynamically, you need to retrieve/get the tab’s index when
you want to close it.

Answer 1

So why can’t you get the index?

$('ul li a').click(function(){ 
    var index = $(this).parent().index($(this).parent());
    alert(index); 
});
