AJAX 后台返回多种数据

前台ajax(jsp文件):

(1)

    $.ajax({
            type: "POST",
            url: "/dragable/demo/finishTopo",
            async:true,
            data: {json: "testDiv",name:"json"},
            dataType: "json",
           // dataType: "text",
            success: function(data){
                alert(data.list + data.total);
            },
            error: function(e) { 
                alert(e); 
            }
        });

(2)

$.ajax({
            type: "POST",
            url: "/dragable/demo/finishTopo",

            data: {json: "testDiv",name:"json"},
            //dataType: "json",
            dataType: "text",
            success: function(data){
                data = data.replace(/'/g, '"');//将所有'替换成"
                var jspare = JSON.parse(data);
                alert(jspare.root[0].value);
            },
            error: function(e) {

        JSONObject json1;
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("total", 56);
        map.put("list", "listjipa");
        json1 = JSONObject.fromObject(map);
