经常碰到客户要求直接从网站主页登录到邮箱，而邮箱系统是imail8.1x,经过一番修改测试，成功登录；8.22版本未试，但应该也适用。现将代码发布供大家分享：

 

'实现登录检查及提交表单

<SCRIPT language=javascript>
<!--
if (top.location !== self.location) {
top.location=self.location;
}

function window_onload() {

 usernameshow.focus();

}

function gook() {

 if (usernameshow.value == "")
 {
  alert("用户名不可为空");
  usernameshow.focus();
  return ;
 }

 if (pwshow.value == "")
 {
  alert("密码不可为空");
  pwshow.focus();
  return ;
 }

 f1.saveUser.value = showsaveUser.checked;
 f1.username.value = usernameshow.value;

 f1.SecEx.value = showSecEx.checked;
 f1.pwhidden.value = encode(pwshow.value, parseInt(f1.picnum.value));

 f1.submit();
}

function encode(datastr, bassnum) {
 var tempstr;
 var tchar;
 var newdata = "";

 for (var i = 0; i < datastr.length; i++)
 {
  tchar = 65535 + bassnum - datastr.charCodeAt(i);
  tchar = tchar.toString();

  while(tchar.length < 5)
  {
   tchar = "0" + tchar;
  }

  newdata = newdata + tchar;
 }

 return newdata;
}
