$ .getJSON无法在我跨域使用吗？

Question

the following code does not work with me:

$.getJSON(url,
         function (data) {
             if (data.results[0]) {
                 alert('hi');

                 $.each(data["Rows"], function (i, el) {
                     $("#target").append("<a href=\"" + el[1] + "\">" + el[2] + "</a><br />");
                 })

                 //container.html(data);
             } else {
                 var errormsg = '<p>Error: could not load the data.</p>';
                 container.html(errormsg);
             }
         });

And here is the url that I pass: http://www.somedomain.com/page.aspx?sid=6BB5B614-4C43-45DF-BA7D-47A71F0753EF&jsoncallback= ? And here is the JSON that returned back

{"Columns":["id","Article_Url","Article_Title","date","num"],
 "Rows":[
   ["5bb93b83-d129-4ca9-8999-ed54910b824d","97.74.67.146/test.html","test","\/Date(1316189236173)\/",25],

 ]
}

What Im doing wrong?!

Answer 1

getJSON is just like any other AJAX -request affected by the same-origin-policy wich forbids doing cross-domain ajax-requests.

you can work around this doing JSONP .

EDIT:
i just read getJSON should do an automatic fallback to jsonp if the URL contains a callback -parameter:

JSONP

If the URL includes the string "callback=?" (or similar, as defined by the server-side API), the request is treated as JSONP instead. See the discussion of the jsonp data type in $.ajax() for more details.

since you're having a jsoncallback -parameter this all might work - but the resonse you posted doesn't use this callback-function (maybe because you're just giving ? as callback-name) so this might be the whole problem: post a functionname as callback and implement that function on your side.
