2.json.ashx页面全部代码

<%@ WebHandler Language="C#" Class="json" %>

using System;
using System.Web;
using System.Web.Script.Serialization;
using System.Collections.Generic;

public class json : IHttpHandler {
   
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
               
        //接受出过来的值  

        string sun = context.Request["array"].ToString();

        //实例化JavaScriptSerializer对象
        JavaScriptSerializer jss = new JavaScriptSerializer();
        List a = new List();

        //把json转换其他list类型
        a = jss.Deserialize(sun, typeof(List)) as List;
        string meg=null;
        foreach (var item in a)
        {
            meg += item.number;
        }
        context.Response.Write(meg);
    }

    public class array
    {
        public int id { get; set; }
        public string number { get; set; }
    }
    public bool IsReusable {
        get {
            return false;
        }
    }

}

 

 

我的代码：

 function ClickPreViewHandle(obj) {
         var divid = $(obj).attr("surfaceid").replace("btnPV", "div")
         var inputvalues = GetSurfaceTextInputValue(divid);
         var inputvaluesJS = $.toJSON(inputvalues);
         jQuery.blockUI({ message: "Generation Image...", css: { padding: 25, color: '#fff', border: '3px solid #aaa', backgroundColor: '#507691'} });
         $.ajax({
             type: "post",
             url: "/PersonalizerPreViewHandler.ashx",
             //dataType: "json",
             data: { 'values': inputvaluesJS },
             success: function (data) {
                 var leftA = divid.replace("div", "divimg");
                 $("#" + leftA + " img").attr("src", data);
                 jQuery.unblockUI();
             },
             error: function (err) {
                 alert("error:" + err);
                 jQuery.unblockUI();
             }
         });
         return false;
     }
