        'url': $(this).attr('img-src')
    },
    function(json) {
        alert(json.crt);
    });http://dfasdfasdf.com?callback=jQuery17107430863014888018_1383632870684&url=http%3A%2F%2Fwww.baidu.com%2Fimg%2Fbdlogo.gif&_=1383634297626
服务端能正常反回信息：jQuery17107430863014888018_1383632870684({"status":0,"url":"http:\/\/mosaic-res.stor.sinaapp.com\/201311\/527895799bebd.gif","crt":1383634297})

Answer 1

你没有回调函数吧$.ajax({
             type : "get",
             async:false,
            url : "http://dfasdfasdf.com,
            dataType : "jsonp",
            jsonp: "callback",
            jsonpCallback:"jsonpCallback"           
        });function jsonpCallback(data){
}
