JQuery UI Tabs caching

I am working in an ASP .net MVC Application. I have a JQuery UI tab whose Javascript to enable caching is as follows.

function LoadStudentDetailTabs() {
    $('#tabStudentDetail').tabs({
        cache: true,
        spinner: '',
        select: function(event, ui) {

            $("#gridSpinnerStudentDetailTabs h5").text("Loading Details...");
            $('#tabStudentDetail > .ui-tabs-panel').hide();
            $("#gridSpinnerStudentDetailTabs").show();
        },
        load: function(event, ui) {
            $("#gridSpinnerStudentDetailTabs").hide();
            $('#tabStudentDetail > .ui-tabs-panel').show();
        },
        show: function(event, ui) {
            $("#gridSpinnerStudentDetailTabs").hide();
            $('#tabStudentDetail > .ui-tabs-panel').show();
        }

}

I constructed three tab items using a list say tab1, tab2, tab3.

Now what happens is when the tab is contructed it enables cahing for all the tab items. But how can I individually set caching to these tab items as needed. Say (tab1 cache, tab2 no cache, tab3 cache) I can only see a way to apply caching to the entire tab rather than applying caching to individual tab items as needed.

There is also a need for me to enable or disable caching to these tab items (tab1, tab2, tab3) dynamically. How can I achieve this. any help would be appreciated?

I recently had a use for this as well. Looking into the code, it uses "cache.tabs" with $.data to determine if a tab should be cached. So you just need to grab the element, and set $.data(a, "cache.tabs", false);

I created a quick extension to do just that, assuming the tabs are static. There may be unforseen issues, and can certainly be improved.

(function($) {
    $.extend($.ui.tabs.prototype, {
        _load25624: $.ui.tabs.prototype.load,
        itemOptions: [],
        load: function(index) {
            index = this._getIndex(index);

            var o = this.options,
                a = this.anchors.eq(index)[0];

            try {
                if(o.itemOptions[index].cache === false)
                    $.data(a, "cache.tabs", false);
            }
            catch(e) { }

            return this._load25624(index);
        }
    });
})(jQuery);

As you can see I assign the old load method to _load25624, just some random name, keeping it as a member of the object, and call it in the new load method after having determined if the tab should be cached. Usage:

$("#tabs").tabs({
    cache: true,
    itemOptions: [
        { cache: false }
    ]
});

Will turn on cache for the entire set of items, and turn off cache for just the first item (index 0).

So, simplifying Eric's analysis, you can control the caching of each tab by setting the 'cache.tabs' data in each tab's anchor element.

// disable cache by default
$("#tabs").tabs({
    cache: false,
});

Then after the tab content has been loaded for the first time, you can enable the caching for that tab. I would simply put it in the $(document).ready:

$(document).ready(function () {
    // cache content for the current tab
    var currentTabIndex = $("#tabs").tabs('option', 'selected');
    var currentTabAnchor = $("#tabs").data('tabs').anchors[currentTabIndex];
    $(currentTabAnchor).data('cache.tabs', true)
});

Thanks, Eric!

Try this

$(document).ready(function(){
  $("#tabs").tabs({
    spinner: 'Loading...',
    cache: false,
    ajaxOptions: {cache: false}
  });
});

None of the above worked for me in IE. I had to put

[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]

At the page level, rather than on the Ajax method (which worked for Chrome)

So:

[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public ViewResult MyPage()
{
}

As well as:

[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public JsonResult MethodCalledByAjax()
{
}
