用FCKeditor提交数据后显示的问题.

Question

提交FCKeditor编辑的内容后保存到数据库.然后用$.getJSON 来显示到页面上来.
我查了输出的JSON格式是正确的.但是就显示不到界面上来.
为什么前台代码  function getData(){
    
    $("#list").html("");//清空列表中的数据
   //发送ajax请求
    $.getJSON("Aritle.ashx", function(json){
     $.each(json,function (i){
           $("#Context").html(json[i].Context);
        }
      );
    });
    }
    </script>后台ashx代码            context.Response.ContentType = "text/plain";
            context.Response.Buffer = true;
           
           DataSet dset = SQLServerDAL.Query("Select * from  Aritcle where ID =7");
           if (dset != null)
           {
              WriteText= Utility.DtToSON(dset.Tables[0]);
           }
           context.Response.Write(WriteText);DtToSON 代码   public static string DtToSON(DataTable dt)
        {
            StringBuilder jsonBuilder = new StringBuilder();
          
            jsonBuilder.Append("[");
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                jsonBuilder.Append("{");
                for (int j = 0; j < dt.Columns.Count; j++)
                {
                    jsonBuilder.Append("\"");
                    jsonBuilder.Append(dt.Columns[j].ColumnName);
                    jsonBuilder.Append("\":\"");
                    jsonBuilder.Append(HtmlDecode(dt.Rows[i][j].ToString()));
                    jsonBuilder.Append("\",");
                }
                jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
                jsonBuilder.Append("},");
            }
            jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
            jsonBuilder.Append("]");
            return jsonBuilder.ToString();
        }
