Query UI Tabs: Changing selected tab | Remembering Active Tab in JQuery UI Tabs | Select last tab by default on Page load, jQuery Ui Tabs | how to set a tab active in jQuery ui tab on page load | Set Jquery ui active tab on page load/reload

I'm using a basic implementation of Jquery UI Tabs that are working fine but I want to set (or reset) the active tab dynamically based on a user action.

<div id="tabs">
    <ul>
        <li><a href="#tabs-1">Tab 1</a></li>
        <li><a href="#tabs-2">Tab 2</a></li>
        <li><a href="#tabs-3">Tab 3</a></li>
    </ul>
    <div id="tabs-1">
        First tab
    </div>
    <div id="tabs-2">
        Second tab
    </div>
    <div id="tabs-3">
        Third tab
    </div>
</div>
<div class='log'></div>

$(function ($) {
    $("#tabs").tabs({
        active: 1,
        create: function (event, ui) {
            var newIndex = ui.tab.parent().children().index(ui.tab);
            $(".log").prepend("<div>Created fired for child=" + newIndex + "</div>");
        },
        activate: function (event, ui) {
            //  Get future value
            var newIndex = ui.newTab.parent().children().index(ui.newTab);
            $(".log").prepend("<div>Activate fired for child=" + newIndex + "</div>");
        },
        beforeActivate: function (event, ui) {
            var newIndex = ui.newTab.parent().children().index(ui.newTab);
            $(".log").prepend("<div>Before activate fired for child=" + newIndex + "</div>");
        }
    });
});

You can manually active a tab using below code (2 is index of tab):
$("#tabs").tabs("option", "active", 2);

JQuery Custom Checkbox Example | Checkbox Customization

It's easy to customize checkbox.

if (app === undefined) var app = {};
app.customCheckBox = (function() {
    var prop = null;

    function base() {
        if (!prop) {
            prop = $.prototype.prop;
            $.prototype.prop = function() {
                var elem = $(this), result = prop.apply(this, arguments);
                if (elem.is(".custom-checkbox-base-element")) {
                    elem.trigger("update_view");

    return {
