The ultimate solution to the problem that the server or virtual host does not support AjaxPro

Method: add a mapping of a.ashx file in the website properties -- home directory -- configuration --

The mapped file path is: C:\WINDOWS\ Microsoft.NET \Framework\ v2.0.50727 \ aspnet_isapi.dll extension:

ashx action: GET, HEAD POST, DEBUG

Check to see if the file exists

The first thing to do is in Web.config < system.web > To add the following

< httpHandlers >
< add verb="POST,GET" path="AjaxPro/*.ashx" type="AjaxPro.AjaxHandlerFactory, axPro" / >

Or (see version)

< add verb="POST,GET" path="ajaxpro/*.ashx" pe="AjaxPro.AjaxHandlerFactory,AjaxPro.2"/ >

< /httpHandlers >

Then add the following line of code to Page_Load on the server side
AjaxPro.Utility.RegisterTypeForAjax(typeof(index));

Let's implement how to invoke server-side methods on the client side using javascript
Server-side method that returns 1 DataSet

 
[AjaxPro.AjaxMethod] 
public DataSet Change() 
{ 
string str="select xjh,xm from xs_jbxx"; 
ds=cla.Bind(str); 
return ds; 
} 

This method is then called on the client side

 
<script language="javascript"> 
function Change() 
{ 
WebServer.index.Change(change_callback) 
} 
function change_callback(response) 
{ 
var ds=response.value; 
var content=document.getElementById("newDG"); 
var table=null; 
for(var i=0;i<ds.Tables[0].Rows.length;i++) 
{ 
if(i==0) 
{ 
table=ds.Tables[0].Rows[i].xm+"<br>"; 
} 
else 
{ 
table+=ds.Tables[0].Rows[i].xm+"<br>"; 
} 
} 
content.innerHTML=table; 
} 
</script>
