一个完整的AjaxPro例子

源代码

 

1.配置文件设置：

<httpHandlers>

<add verb="*" path="*.ashx" type="AjaxPro.AjaxHandlerFactory,AjaxPro.2"/>

</httpHandlers>

2.编写自定义方法（可选，但用这个方法性能可以提高10倍左右，原来注册要300ms，优化后只要10-15ms）

 

  public   static   void  RegAjax(HtmlHead Header,Type type)
        {
             //  用来代替 AjaxPro.Utility.RegisterTypeForAjax(Type type);方法
             string  assemblyName  =  type.FullName  +   " , "   +  type.Assembly.FullName.Substring( 0 , type.Assembly.FullName.IndexOf( " , " ));
             if  (type.Assembly.FullName.StartsWith( " App_Code. " ))
                assemblyName  =  type.FullName  +   " ,App_Code " ;
            Literal l  =   new  Literal();
            l.Text  =   " \n<script type=\ " text / javascript\ "  src=\ " / ajaxpro / prototype.ashx\ " ></script>\n "
             +   " <script type=\ " text / javascript\ "  src=\ " / ajaxpro / core.ashx\ " ></script>\n "
             +   " <script type=\ " text / javascript\ "  src=\ " / ajaxpro / converter.ashx\ " ></script>\n "
             +   " <script type=\ " text / javascript\ "  src=\ " / ajaxpro / "  + assemblyName +  " .ashx\ " ></script>\n " ;
            Header.Controls.Add(l);
        }

 

  public   static   void  RegAjax(HtmlHead Header)
        {
             //  用来代替 AjaxPro.Utility.RegisterTypeForAjax(Type type);方法
            Literal l  =   new  Literal();
            l.Text  =   " \n<script type=\ " text / javascript\ "  src=\ " / ajaxpro / prototype.ashx\ " ></script>\n "
             +   " <script type=\ " text / javascript\ "  src=\ " / ajaxpro / core.ashx\ " ></script>\n "
             +   " <script type=\ " text / javascript\ "  src=\ " / ajaxpro / converter.ashx\ " ></script>\n "
             +   " <script type=\ " text / javascript\ "  src=\ " / ajaxpro / fisha.DAL.PersionDao,fisha.ashx\ " ></script>\n " ;
            Header.Controls.Add(l);
        }

// fisha.DAL.PersionDao 用来存方[AjaxPro.AjaxMethod]的类名，命名空间+类名
// fisha.ashx 中的fisha为程序集的名称

 

3.编写服务器端方法

 

namespace  fisha.DAL
{
     public   class  PersionDao
    {
         public  DataTable GetTable()
        {
            DataTable dt  =   new  DataTable( " persion " );
            DataColumn dc1  =   new  DataColumn( " name " , Type.GetType( " System.String " ));
            DataColumn dc2  =   new  DataColumn( " age " , Type.GetType( " System.Int16 " ));
            dt.Columns.Add(dc1);
            dt.Columns.Add(dc2);

             // 以上代码完成了DataTable的构架，但是里面是没有任何数据的
             for  ( int  i  =   0 ; i  <   10 ; i ++ )
            {
                DataRow dr  =  dt.NewRow();
                dr[ " name " ]  =   " 小小 " ;
                dr[ " age " ]  =   10 ;
                dt.Rows.Add(dr);
            }
             return  dt;
        }

        [AjaxPro.AjaxMethod]
         public  IList < MyClass >  GetList()
        {
            DataTable tab_data  =  GetTable();
            IList < MyClass >  myClassList  =   new  List < MyClass > ();
             if  (tab_data.Rows.Count  >   0 )
            {
                 for  ( int  i  =   0 ; i  <  tab_data.Rows.Count; i ++ )
                {
                    DataRow dr  =  tab_data.Rows[i];
                    MyClass item  =   new  MyClass { Name = dr[ " name " ].ToString(), Age = Convert.ToInt16(dr[ " age " ].ToString())};
                    myClassList.Add(item);
                }
            }
             return  myClassList;
        }
    }

   public   class  MyClass
    {
         private   string  name  =   string .Empty;
         private   int  age  =   0 ;

         public   string  Name
        {
             get  {  return  name; }
             set  { name  =  value; }
        }

         public   int  Age
        {
             get  {  return  age; }
             set  { age  =  value; }
        }
    }
}

 

4.新建一个aspx页面 test.aspx

===test.aspx.cs代码==

 

public   partial   class  test : System.Web.UI.Page
    {
         protected   void  Page_Load( object  sender, EventArgs e)
        {
            BasicDao.RegAjax(Header,  typeof (fisha.DAL.PersionDao)); 
             // 用自定义的方法，向客户端注册脚本
        }
    }

 

===test.aspx代码==

 

 

< script language = " javascript "  type = " text/javascript "  defer = " defer " >  
     function  ShowList()
    {
         var  res = fisha.DAL.PersionDao.GetList().value;
         var  tab = document.getElementById( " tab " );
         var  tblHtml  =   "" ;
         if (res)
        {
             // res是服务器返回的一个List<MyClass>集合
             for ( var  i = 0 ;i < res.length;i ++ )
            {
                tblHtml += res[i].Name + " . " + res[i].Age + " <br/> " ;
                 // 从上面可以看出可以直接调用List<City>集合中的元素和它们的属性
            }
        }
        tab.innerHTML = tblHtml;
    }
< / script>

< a href = " javascript:ShowList();void(0); " > here < / a>
     < div id = " tab " >
     < / div>
