Developer on Alibaba Coud: Build your first app with APIs, SDKs, and tutorials on the Alibaba Cloud. Read more ＞
First, you must create a website to create the following files: Web forms (Default. asp tutorial x), JScript File (ajax. js), Web service (SayHelloService. asmx), Class (Hello. cs)
(Add: you need to add a Microsoft. Web. Preview. dll file to download it from CSDN)
 
  • Default. aspx front-end code:
<Supplement> you need to create a new ScriptManager control to partially refresh ajax data. 
  

   

    <% @ Page Language = "C #" AutoEventWireup = "true" CodeFile = "Default. aspx. cs" Inherits = "_ Default" %>
    

    
<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    

    
<Html xmlns = "http://www.w3.org/1999/xhtml">
    
<Head runat = "server">
    
<Title> </title>
    
</Head>
    
<Body>
    
<Form id = "form1" runat = "server">
    
<Asp: ScriptManager ID = "ScriptManager1" runat = "server">
    
<Scripts>
    
<Asp: ScriptReference Assembly = "Microsoft. Web. Preview" Name = "PreviewScript. js"/>
    
<Asp: ScriptReference Path = "~ /Ajax. js "/>
    
</Scripts>
    
<Services>
    
<Asp: ServiceReference Path = "~ /SayHelloService. asmx "/>
    
</Services>
    
</Asp: ScriptManager>
    

    
<Div>
    
<Input id = "btnSayHello" type = "button" value = "SayHello"/>
    
<Div id = "result"> </div>
    
</Div>
    
</Form>
    
</Body>
    
</Html>
  • Ajax file code:
<Supplement> the role of Preview. dll is here, in order to make the compatriots who are used to the background encoding of the asp.net tutorial feel familiar .... 
  

   

    
     

      Var btnSayHello;
      
Var lblResult;
      

      
Sys. Application. add_init (onPageInit );
     

     

       
     

     

       
     

     

       
     

     

      

      
Function OnFailded (error)
      
{
      
LblResult. set_text ("Call failed. Error message: "+ error. get_message ());
      
} Function OnSucceeded (resultText)
      
{
      
LblResult. set_text (resultText );
      
 }
     
Function btnSayHello_onClick ()
{
SayHelloService. SayHello (OnSucceeded, OnFailded );
} Function onPageInit ()
{
BtnSayHello = new Sys. Preview. UI. Button ($ get ("btnSayHello "));
BtnSayHello. initialize ();
    
LblResult = new Sys. Preview. UI. Label ($ get ("result "));
LblResult. initialize ();
    
BtnSayHello. add_click (btnSayHello_onClick );
}

   
Code of the SayHelloService. cs file:
<Supplement> the function of this Web service class is to construct a "communication platform" between js files and common classes ".
In fact, this can also be done in basic classes. However, to a certain extent, you must add keywords such as [ScriptService] and [WebMethod] to the basic classes to "pollute" the basic classes.
Remember to add keywords such as [ScriptService] and [WebMethod]. Remember to add the [WebMethod] keyword before every time you write a function.
