三星智能电视中的JQuery.Ajax不显示

Question

I used JQuery.Ajax to try to communicate with my webservice

Here is how the code looks like:

Main.onLoad = function() {
    // Enable key event processing
    this.enableKeys();
    widgetAPI.sendReadyEvent();
    //$("#h2Test").html("Change On Text");

        $.ajax({
                    url : 'http://---.--.---.--:-----/_layouts/-----/------.asmx?op=retrieveEvents',
                    type : "POST",
                    dataType : 'json',
                    contentType : 'application/json',
                    data : {
                        url : "someURL"
                    },
                    success : function(response) {
                        $("#h2Test").html("SUCCESS");
                    },
                    failure : function(response) {
                        $("#h2Test").html("FAIL");
                    }
        });
};

When i run the codes, Change On Text is displayed instead of SUCCESS or FAIL, why doesn't the code reaches either success or error

Answer 1

According to http://api.jquery.com/jQuery.ajax/ you should replace your

failure: function(response) {

with

error: function(response) {

It probably should reach the error function then.

Answer 2

In mobile and tv apps you should take care about "same domain policy" by using: dataType: "jsonp" and jsonpCallback (also declaring the latter). Take a look:

http://api.jquery.com/jQuery.ajax/

and

Callback function for JSONP with JQuery ajax
