    type: "GET",
    url: "http://myurl.com/webservice&callback=?",          
    contentType: "application/json; charset=utf-8",
    crossDomain: true,
    dataType: "jsonp",
    data: "{}",
    Accept: "",
    beforeSend: setHeader,
    success: OnGetAllMembersSuccess,
    error: OnGetAllMembersError,                
    });
});     
function setHeader(req) {
    req.setRequestHeader("Authentication", "Basic credentials");
    req.setRequestHeader("Content-Type", "application/json");
    req.setRequestHeader("Accept", "application/json");
}    

function OnGetAllMembersSuccess(data, status) {
    alert(status);
    $.each(data.result, function(key, value) {              
        $("#result").append(key+" : "+value);
        $("#result").append("<br />");
    });
}

function OnGetAllMembersError(request, status, error) {
    alert(status);
}   

推荐答案

使用jsonp作为dataType时，您需要在服务器端绑定一个回调函数. 例如，如果您需要一个像{"id":"myId"}这样的json响应，则在服务器端应该像"mycallback({" id:" myId})";

While using jsonp as dataType, you need to bind a call back function in the server side.. for example, if you need a json response like {"id":"myId"}, at the server side it should be return like "mycallback({"id":"myId"})";

此外，您也需要在客户端编写该函数.

Also you need to write that function in client side too.

function mycallback(json)
{alert(json);}
