Navigation in javascript widget using JSONP

Question

I am working on javascript widget which can be shown on any site.

see.

• Show JS(jQuery) widget on any site, with ASP.NET MVC server side
• Embeddable widgets using jQuery and ASP.NET MVC

and for now I faced with issue, when I need to navigate between pages in widgets. See code below. But for now I am confused how to organize navigation (link clicking, ajax updating) in html that comes from server, to make it working as without widget, because I want to debug it as usual page.

<img alt="TEST" onclick="window.zs.LoadStep1('ad507a69-d882-41d4-8300-bd9f7163d419',this);" style="cursor:pointer;"/>

;
(function (window, ZS, undefined) {
    var zs = window.zs = ZS || {};
    zs.Version = "v1_0";
    zs.baseUrl = "http://localhost/w/";
    var jQueryScriptOutputted = false;
    var containerSelector = '#zaprosWidgetContainer';
    function initJQuery() {
        if (typeof (jQuery) == 'undefined') {
            if (!jQueryScriptOutputted) {
                jQueryScriptOutputted = true;
                document.write("<scr" + "ipt type=\"text/javascript\" src=\"http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js\"></scr" + "ipt>");
            }
            setTimeout("initJQuery()", 50);
        }
    };

    function initContainer() {
        if ($(containerSelector).length == 0) {
            $('<div id="zaprosWidgetContainer" style="width=500px;height:500px;"></div>').appendTo('body');
        }
    }

    zs.LoadStep2 = function (serviceId) {
        $.ajax({
            url: zs.baseUrl + 'Wizard/Step2JsonP?jsoncallback=?',
            data: { serviceId: serviceId },
            type: "GET",
            dataType: "jsonp",
            jsonpCallback: "callBack",
            success: function (json) {
                $(containerSelector).html(json.Html);
            }
        });

    },
    zs.LoadStep1 = function (providerId) {
        $(function () {
            $.ajax({
                url: zs.baseUrl + 'Wizard/Step1JsonP?jsoncallback=?',
                data: { providerId: providerId },
                type: "GET",
                dataType: "jsonp",
                jsonpCallback: "callBack",
                success: function (json) {
                    $(containerSelector).html(json.Html);
                }
            });

        });
    };
    initJQuery();
    initContainer();

})(window, window.zs || {});

I understand that you want to navigate to LoadStep1/LoadStep2 without ajax-style?

You could create a master page in ASP.NET that has a link/button to navigate to the next step. That link is generated as part of the previous step.

Eg on the output html of Step1 add

 <a href="/.../Step2InMaster?serviceID=13">Next Step</a>

Can you tell us why you have to create a "non-widget mode" for debugging? What's the difference for debugging?

Something else about JsonP that helped me:

You can also extend your JsonP class that wraps the JSON data into a JsonP string to support returning normal JSON when no callback method is supplied - this way you can use the same uri to return the html directly. I use that to allow widgets run in JsonP and Json simultaneously.
