下面代码可以帮你取到picnum的值,刷新可以发现这个picnum是动态改变的。然后用encode加密用户密码和picnum,作为表单项目提交,就好了。
f1.pwhidden.value = encode(pwshow.value, parseInt(f1.picnum.value))
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;
}
