Preliminary Research on AJAX

Ajax is the most popular nowadays. It's vanity and vanity that the customer wants to use it.
It also satisfies my curiosity.
After a lot of searching and filtering on the internet, I would like to recommend a better one.
Ajax. Net wrapper. I don't know if my brother has used it in the garden. I will give a brief introduction below.
1 download http://ajax.schwarz-interactive.de/download/
The example is http://ajax.schwarz-interactive.de/download/ajaxsample.zip
2. Install and drop the Ajax. dll under the bin and reference it.
Add
<Configuration>
<System. Web>
<Httphandlers>
<Add verb = "post, get" Path = "ajax/*. ashx" type = "Ajax. pagehandlerfactory, Ajax"/>
</Httphandlers>
...
<System. Web>
</Configuration>
Okay.
3. Add the following in the onload event of the page where it is used: Code Private   Void Page_load ( Object Sender, eventargs E) {< br> Ajax. utility. registertypeforajax ( typeof (INDEX ));
//
}

then write the following function in the other [class that you need to use to return results] [Ajax. ajaxmethod ()]
Public int serversideadd ( int firstnumber, int secondnumber)
{< br> return firstnumber + secondnumber;
}

in the future, the system will create a JavaScript function named serversideadd.
on your page, use
JavaScript to access var S = serversideadd );
alert (S. value);
it seems that this is relatively simple to use, that is, JS requires a higher skill, of course, Ajax is not a JS guru
Haha
here is just a introduction. He can still return dataset. If you are interested, please refer to his example.
