这个不是人编的，是asp.net程序由客户端处理过以后生成的发送到客户端的javascript代码。

<input type="hidden" name="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" value="dDwyMTExMzI1OTUxO3Q8O2w8aTwxPjs+O2w8dDw7bDxpPDE+Oz47bDx0PDtsPGk8Mj47PjtsPHQ8cDxsPFZpc2libGU7PjtsPG88Zj47Pj47Oz47Pj47Pj47Pj47PsudoRXWIDqQ2b6fRQNLjvciK9E4" />是页面状态信息，重要的数据才要发送到服务器，有些不重要的用户信息就放再客户端存在这里了。

<script language="javascript" type="text/javascript">
<!--
function __doPostBack(eventTarget, eventArgument) {
var theform;
if (window.navigator.appName.toLowerCase().indexOf("microsoft") > -1) {
theform = document._ctl0;
}
else {
theform = document.forms["_ctl0"];
}
theform.__EVENTTARGET.value = eventTarget.split("$").joi
