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);
}
{
// 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
{
// 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; }
}
}
}
{
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>
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>
