一个完整的AjaxPro例子

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>
