        minimumInputLength: 0,//输入多少长度的值的时候执行后台请求查询

                contentType: 'application/json'//此处可修改contentType类型（这个地方坑了我好久，不知道还要加params包起来）

            type: "post",//请求类型
            data: function (term, page) {//传给后台的参数，可自行构造
                return JSON.stringify({
                    prefix: term,
                    limit: 4,

            },
            results: function (data, page, query) {        //请求成功，接收返回值       
                var more = (page * 4) < data.result.totalCount;
                return { results: data.result.items, more: more };
            },
        }
    });
