simple REST call from Javascript

Question

I am trying to call my service from here http://diningphilospher.azurewebsites.net/api/dining

using below javascript,

$.ajax(
{
    type: "GET",
    dataType: "json",
    url: "http://diningphilospher.azurewebsites.net/api/dining/",
    success: function (data) 
    {
        alert(data);
    }
});

But I am getting error relating cross origin. I see people suggest using JSONP but I guess my server does not support JSONP. I studied CORS and could not understand the head or tail of it. I would like to know the way around to read the JSON that sits in different domain.

What do you not understand about CORS? What server are you running? I pretty sure it can handle json. — Musa

@Musa, Currently if i use this I get CORS error. How to fix that. I was told to add a Access-Control-Request-Allow-method as part of request. I cannot find a simple working example. All i see is W3C docs. Is there a links showing how to enable CORS in client side through examples — Ajax3.14

Try adding this Access-Control-Allow-Origin: * http header. — Musa

url is outputting xml not json or jsonp. As far as server supporting jsonp... jsonp is just text output that is parsed by browser as script — charlietfl

@charlietfl great catch. you are right, I am now working to remove the default formatter from xml to json.hope it works — Ajax3.14

I hope this should work:

$.ajax(
{
    type: "GET",
    dataType: "jsonp",
    url: "http://diningphilospher.azurewebsites.net/api/dining/",
    success: function (data) 
    {
        alert(data);
    }
});

Or just add/append ?callback=? along with your cross-domain url.
