AjaxPro.2.dll在VS2005使用中的基本使用
个人常用的东西收集起来，也给大家一起分享哈。
AjaxPro.2.dll在VS2005使用中的基本使用
,下面介绍了基本的配置和最简单的使用方法
AJAX不用说大家都明白,不明白的请百度或Google一下人家比我说的专业,笔者写此篇文章不在于介绍多深奥的东西,这样只举一个很简单的例子来引导到大家.此例只为让大家明白AJAX的基本的调用需要做那些事情笔者用的是VS2005引用AJAX2.0程序集( AjaxPro.2.dll) 。
在web.config文件中的＜system.web＞加入以下设置
<
httpHandlers
>
<
add
verb
="POST,GET"
path
="ajaxpro/*.ashx"
type
="AjaxPro.AjaxHandlerFactory,AjaxPro.2"
/>
</
httpHandlers
>
3. 创建一个页面Default.aspx
4. 在Default.aspx.cs文件的Page_Load中注册AJAX可调用的类的名称
protected
void
Page_Load(
object
sender, EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(_Default));
}
5. 创建AJAX可调用的方法:
[AjaxPro.AjaxMethod]
public
string
SetTb(
string
name)
{
return name;
}
注意:[
AjaxPro.AjaxMethod]是定义
AjaxPro可调用的方法,是必须要注明的
6. 前台代码:

"

"

=
"
Default.aspx.cs

function comit_onclick()
{
var name=document.getElementById("tb1").value;
_Default.SetTb(name,callback);
}
function callback(res)
{
document.getElementById("tb").value=res.value;
}
// ]]>

<br /><asp:TextBox ID="tb" runat="server"></asp:TextBox>

</html>
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
}
}

注意:这里值得注意的地方是 _Default.SetTb(name,callback);这句话是为了调用_Default.aspx.cs后台代码中SetTb这个方法的,如果这个方法没有要传递的参数则指明返回的处理方法是哪一个就OK了,写成_Default.SetTb(callback);
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>
