$.ajax({
        type: "GET",
        url: "http://110.188.70.244:8090/idp/restful/getIDPToken",
        dataType: 'jsonp',
        data: {
            appId: 'xxhxm',
            remoteIp: '127.0.0.1'
        },
        jsonp: 'jsonpCallback',
        jsonpCallback: 'successCallback',
        success: function(response){
            console.log(response);
        },
        error:function(jqXHR, textStatus, errorThrown){
            console.log(jqXHR);
            console.log(textStatus);
            console.log(errorThrown);
        }
    });

    function successCallback(r){
        console.log(222)
    }

或者

function getdata(r){
    console.log(222)
}
$.ajax({
    type:'GET',
    url:"http://api.bing.com/qsonhs.aspx",
    data: {
        type: 'cb',
        cb: 'getdata',
        q: '1'
    },
    dataType:"jsonp",
    async:false,
    jsonp:"getdata",
    jsonpCallback:"getdata",
    success:function(data) {
