5秒后自动跳到系统<a href="login.aspx">登录界面</a>...还剩<span id="time" style="font-weight:bold;color: blue">5</span>秒！
<script type="text/javascript">
var i = 5;
window.onload = function page_cg() {
document.getElementById("time").innerText = i;
i--;
if (i == 0) {
window.location.href("login.aspx");
}
setTimeout(page_cg, 1000);
}
</script>
)
