Usage:
1. Add
<! -- Ajax -->
<Httphandlers>
<Add verb = "post, get" Path = "ajax/*. ashx" type = "Ajax. pagehandlerfactory, Ajax"/>
</Httphandlers>
2 ajaxtest. BR, ajaxtest indicates the business processing class
Add the Ajax. ajaxmethod () attribute to the method called on the client for this class
3. Add
<SCRIPT src = "ajax/common. ashx" type = "text/JavaScript"> </SCRIPT>
<SCRIPT src = "ajax/ajaxscript. ashx? Type = ajaxtest. BR, ajaxtest "type =" text/JavaScript "> </SCRIPT>
Note that the type of the ajaxscript. ashx file is the class to be called. If the type is set, all methods with Ajax. ajaxmethod () attributes in the class can be accessed on the client. <HTML>
<Head>
<SCRIPT src = "ajax/common. ashx" type = "text/JavaScript"> </SCRIPT>
<SCRIPT src = "ajax/ajaxscript. ashx? Type = ajaxtest. BR, ajaxtest "type =" text/JavaScript "> </SCRIPT>
<SCRIPT>
// The last parameter is the callback method. Triggered after interaction with the background
BR. getxmldatarows ('xt _ name_t ', 'A', 'test data', showmsg );
BR. getxmldatarows ('xt _ name_t ', 'A', 'test data', showmsg );
// Return value of Method s
Function showmsg (s ){
VaR Doc = new ajaxdom (s );
Document. Write (Doc. selectsinglenode ("DOC/t"). Text );
}
// If there is no callback method, the system will wait for the data to be read...
Document. Write (Br. showmsg ());
Document. Write (Br. showmsg ());
</SCRIPT>
</Head>
<Body>
</Body>
</Html>
This is easy. When I have time, I will port the data lifetime and some client components, as it is.
