发送Ajax请求获取JSON格式数据

Aspx前端页面：

 

ajax一般处理程序页面：

namespace WebFormTest.Ajax
{
    /// 

    /// $codebehindclassname$ 的摘要说明
    /// 
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    public class TestAjax : IHttpHandler
    {
        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            //string json ="{\"Person\":[{\"Age\":18,\"Name\":\"张三\",\"Sex\":\"男\"}]}";

            StringBuilder successMessage = new StringBuilder();
            StringBuilder failedMessage = new StringBuilder();
            successMessage.Append(@"11\t11\t11\r\n22\t22\t22\r\n33\t33\t33\r\n"); // \t制表转义符（空格效果） \r\n换行转义符
            failedMessage.Append(@"11\t11\t11\r\n22\t22\t22\r\n33\t33\t33\r\n");

            string result = "结果信息";
            // \\r\\n转义后为\r\n在前端浏览器解析后为换行
            string message = "发放失败：\\r\\n" + failedMessage.ToString() + "\\r\\n\\r\\n发放成功：\\r\\n" + successMessage.ToString(); 
string json = "{\"result\":\"" + result + "\",\"message\":\"" + message + "\"}"; //注意转义
            context.Response.Write(json);
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}
