vue如何将ajax获取的数据放入变量

        var vm = new Vue({
        el:"#example-1",
        data: {
           items:[]
        },
        ready: function() {
            var self = this;
            $(document).ready(function(){
                $.post("http://xxxx.com/index.php/Home/Test/test",
                    {
                        robot:"123",
                    },
                    function (data, Status) {
                        self.items = JSON.stringify(data);
                    }, "jsonp");
            });
        }
    })

jquery的ajax方法把数据确实获取到了的，
