我把网页内容保存下来，把没用的全部删掉，现在网页上面只剩下一个两个框框，用于输入账户和密码，在登录的时候发现post信息中还是会出现随机数据，现在有点迷糊了，这个随机的数据是怎么生成的？大家能帮我看看么？？
网页代码如下，
<!DOCTYPE html><html xml:lang="en" lang="en" style="height: 100%; "><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>EasyHits4U.com - Your Traffic Exchange, 1:1 Exchange Ratio, Manual Surfing, Innovative Referral Program. FREE Traffic!</title></head><body style="position: relative; min-height: 100%; top: 0px; "><table cellpadding="0" cellspacing="0" border="0" valign="top" width="19%"> <tbody><tr> <td width="235" valign="top" class="left_column"><form action="http://www.easyhits4u.com/account.cgi" method="post"> <input type="hidden" name="f" value="logon"> <input type="hidden" name="manual" value="1"> <input type="hidden" name="fb_id" value=""> <input type="hidden" name="fb_token" value=""> <!-- <input type="hidden" name="google_code" value=""> --> <div style="width:175px; padding-left:16px; padding-right:0px; font-size:11px; padding-top:8px; ">Username or Email:<br> <input type="text" name="username" size="30" class="login" value="" style="border: 1px solid rgb(109, 191, 109); "><br> Password:<br> <input type="password" name="password" class="login" value="" style="border: 1px solid rgb(109, 191, 109); "><br> <div align="center"> <input type="image" id="enter_btn" alt="Enter" title="Enter"> <div id="fb-root"></div></div> </div></form></td> </tr></tbody></table>
大家觉得这个随机数是怎么加上去的，谢谢了，问过其他人，有说是从js中计算出来，在加上去的，可是我修改过的网页已经没有连接js文件了，它一样可以生成随机数据。
我抓取到的post的信息如下,其中最后一行就是要发送的数据，包括用户名，密码，最后面的x,y就是随机数据，现在不知道这两个数据是怎么来的。。

可能JS动态添加的，你看下提交调用方法，用浏览器开发工具看下，提交后表单的HTML
你说的是查看提交后显示的网页代码么？
