使用jquery ajax从跨域进行JSON解析

我正在尝试从跨域解析json，但是在jquery插件中出现错误，例如 405(不允许使用方法)(仅使用来自Google的最新插件)，任何解决方案或建议都将对我.

Im trying to parse json from cross domain but im getting error like 405 (Method Not Allowed) in jquery plugin (im using latest plugin only from google) Any solution or suggestions will be great help for me.

谢谢 巴莎

这是我的代码

$(document).ready(function() {
    $.ajax({
    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);
}
