解决方案 »

  1.   

    改成queryParams: { "action": "query" },看看新不行，还不行看看你返回的json
    这是我以前做的 你可以改改 http://blog.csdn.net/chenmoonhan/article/details/11798443
      

  2.   

    你直接调用  query()  看是不是有数据返回了。
      

  3.   

     Response.Write("{'total。。输出的内容中'全部替换为\"
      

  4.   

    仿着easyui的demo上的json格式写 肯定没问题啊
