Question

I am building a “check-out” like interaction with jQuery UI tabs. This means that the click of a button on the first tab will deactivate the first tab and move to the next. I have been combing through the posts on Stack Overflow but nothing I try seems to work. I am using jQuery UI 1.8, here is the code:

$(document).ready(function() {
    var $tabs = $('#tabs').tabs({ selected: 0 }); 
    $tabs.tabs('option', 'selected', 0);
    $("#tabs").tabs({disabled: [1,2]});
    $("#addstudent").click(function(){
        $tabs.tabs('option', 'selected', 1);
        $("#tabs").tabs({disabled: [0,2]});
    }); 
    $("#confirm").click(function(){
        $tabs.tabs('option', 'selected', 2);
        $("#tabs").tabs({disabled: [0,1]});
    }); 
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.8.24/jquery-ui.min.js"></script>
<div id="tabs">
    <ul>
        <li><a href="#fragment-1">Student Information</a></li>
        <li><a href="#fragment-2">Confirmation</a></li>
        <li><a href="#fragment-3">Invoice</a></li>
    </ul>
    <div id="fragment-1">
        <button id="addstudent" >Add Student</button>
    </div>
    <div id="fragment-2">
        <button id="confirm" >Confirm</button>
    </div>
    <div id="fragment-3">
        tab 3, index 2
    </div>
</div>

When I click the buttons, the next tab becomes unlocked (in that it is selectable) but it does not disable the tab at index 0 and switch to the tab at index 1. Also, the corresponding panel does not show.

Try changing your code to this:

var $tabs = $('#tabs').tabs({ selected: 0, disabled: [1,2] }); 
$("#addstudent").click(function(){
   $tabs.tabs('enable', 1).tabs('select', 1).tabs('disable', 0);        
}); 
$("#confirm").click(function(){
    $tabs.tabs('enable', 2).tabs('select', 2).tabs('disable', 1);    
});
