1, Tudou:
When the Tudou registered, found a user nickname, the text box at the end of an icon quickly flashed, below gives "the nickname has been occupied" hint. Well, it's a bit of an Ajax shadow.
Analyze the page (http://www.toodou.com/register/register.php) and immediately find the code for AJAX.
<!--Private Javascript-->
<script type= "Text/javascript" src= "/script/register.js" ></script>
<!--Ajax Framework-->
<script src= "/js/toodou.js" type= "Text/javascript" ></script>
<script src= "/js/zajax.js" type= "Text/javascript" ></script>
<script src= "/js/zz_util.js" type= "Text/javascript" ></script>
<script src= "/js/zz_string.js" type= "Text/javascript" ></script>
<script src= "/js/zz_register_func.js" type= "Text/javascript" ></script>

Among them, Zajax.js is the Ajax Framework used by potatoes. The framework changes from Sajax, increases the freedom of the call, and improves the Chinese invocation on the server side. Its copyright information is as follows:
Zajax v 0.10
Made by Tudou Zarz (http://www.toodou.com/)
Based on Sajax 0.10 (http://www.modernmethod.com/sajax/)
Split the SAJAX server and client programs, increased the freedom of invocation, improved Chinese support on the service side
Here is not the code posted out, interested in their own can be download down to study.
