js定时关闭页面 和 ext 一些操作

var sysCountDownTime = 3;
var timeId; //定时器句柄，用于点击返回时取消定时
var vTime = 0;

function show_secs()
{
try
{
var exitTime  = sysCountDownTime - vTime;
vTime++;
if (exitTime < 1) {
window.clearTimeout(timeId);
return redirect();
}
document.getElementById("tno").innerText =  exitTime;
timeId=window.setTimeout('show_secs()',1000);
}
catch(e)
{}
}
