Ajax加载数据的使用

需求就是不能再进入页面时加载数据，只能在点击其中一个按钮时把数据加载呈现出来。具体效果如最下面的图。

1、前台页面

1 <h1 class="title" id="001" name="001" onclick="GetData(1)">
2     概述 <span class="title_icon"></h1>
3  <div class="mc_list" id="div001" style="display: none">
4
5   </div>

2、ajax代码

 1 GetData(n){
 2    $.ajax({
 3                         type: "get",
 4                         url: "GetDataHander.ashx?para=" + n + "&jbid=" + jbid,
 5                         dataType: "json",
 6                         success: function (data) {
 7                             $.each(data, function (idx, item) {
 8                                 $("#div00" + n).empty();
 9                                 $("#div00" + n).append("<span style=‘font-family:黑体;font-size:14pt;‘>" + item.DisArticleInfo_Title + "</span></br>" + item.DisArticleInfo_Info + "<br/>");
10                             });
11                         }
12                     });
13 }

3、ashx页面

 1  public void ProcessRequest(HttpContext context)
 2         {
 3             context.Response.ContentType = "text/plain";
 4             string para = context.Request["para"].ToString();
 5             DataTable dt = new DataTable();
 6             DataTable dt1 = new DataTable();
 7             DataTable dt2 = new DataTable();
 8             DataTable dt3 = new DataTable();
 9             DataTable dt4 = new DataTable();
10             string str = string.Empty;
11             if (para == "1")
12             {
13                 dt = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and (DisArticleInfo_ArticleTypeId=24 or DisArticleInfo_ArticleTypeId=1)", " DisArticleInfo_ID desc").Tables[0];
14             }
15             if (para == "2")
16             {
17                 dt = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=16", " DisArticleInfo_ID desc").Tables[0];
18             }
19             if (para == "3")
20             {
21                 dt = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=2", " DisArticleInfo_ID desc").Tables[0];
22             }
23             if (para == "4")
24             {
25                 dt = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=18 ", " DisArticleInfo_ID desc").Tables[0];
26                 dt1 = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=19 ", " DisArticleInfo_ID desc").Tables[0];
27                 dt2 = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=21 ", " DisArticleInfo_ID desc").Tables[0];
28                 dt3 = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=22 ", " DisArticleInfo_ID desc").Tables[0];
29             }
30             if (para == "5")
31             {
32                 dt = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=8 ", " DisArticleInfo_ID desc").Tables[0];
33                 dt4 = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=9 ", " DisArticleInfo_ID desc").Tables[0];
34             }
35             if (para == "6")
36             {
37                 dt = disbll.GetList(1, " DisArticleInfo_DiseaseId=" + context.Request["jbid"] + " and DisArticleInfo_ArticleTypeId=4", " DisArticleInfo_ID desc").Tables[0];
38             }
39             if (dt.Rows.Count > 0)
40             {
41                 str =JsonConvert.SerializeObject(dt,new DataTableConverter());
42                 if (dt1.Rows.Count > 0|| dt2.Rows.Count > 0 || dt3.Rows.Count > 0)
43                 {
44                     dt.Merge(dt1);
45                     dt2.Merge(dt3);
46                     dt.Merge(dt2);
47                     str = JsonConvert.SerializeObject(dt, new DataTableConverter());
48                 }
49                 if (dt4.Rows.Count>0)
50                 {
51                     dt.Merge(dt4);
52                     str = JsonConvert.SerializeObject(dt, new DataTableConverter());
53                 }
54             }
55             context.Response.Write(str);
56             context.Response.End();
