我在我们的店里安装了安全摄像头。我希望将其安排为在一周的不同时间转向特定预设。
我目前的代码如下:
<html>
<body>
<SCRIPT type='text/javascript'language='javascript'>
var IPandPort = "ip:port
var user = "user"
var pwd = "pass"
var poPreset = "31";
var shopPreset = "33";
function shop_preset()
{
action_zone.location ='http://'+IPandPort+'/'+'decoder_control.cgi?user='+user+'&pwd='+pwd+'&command='+shopPreset;
}
function postoffice_preset()
{
action_zone.location ='http://'+IPandPort+'/'+'decoder_control.cgi?user='+user+'&pwd='+pwd+'&command='+poPreset;
}
</SCRIPT>
<input id="Post Office" type="button" value="Post Office" onclick="doFunction(postoffice_preset());" />
<input id="Shop" type="button" value="Shop" onclick="doFunction(shop_preset());" />
<IFRAME style="DISPLAY: none" src="" name=action_zone>
</IFRAME>
</body>
</html>
我想以最简单的方式实现的是: 周一至周五: 上午 7 点 - postoffice_preset() 下午 6 点 - shop_preset()
周六: 上午 7 点 - postoffice_preset() 下午 1 点 - shop_preset()
太阳: 没做什么。即:它保留在之前设置的shop_preset()上。
我不确定这是否完全可能。这将在 Internet Explorer 中的最小化窗口上运行，并且永远不会与之交互。
最佳答案
您可以使用 setInterval() 来实现此目的。
那么你的代码可能是这样的:
var IPandPort = "ip:port";
var user = "user";
var pwd = "pass";
var poPreset = "31";
var shopPreset = "33";
var nIntervId;
// When the window is loaded, run the schedule.
window.onload = schedule();
function schedule() {
// If there's a timer already running, clean it.
if (typeof(nIntervId) != "undefined") {
clearInterval(nIntervId);
}
// Run the positionCamera function every minute.
nIntervId = setInterval(positionCamera, 60000);
}
function positionCamera() {
var now = new Date();
var weekDay = now.getDay();
var hour = now.getHours();
// Mon-Sat, 7am.
if (weekDay >= 1 && weekDay <= 6 && hour == 7) {
postOfficeCamera();
}
// Mon-Fri, 6pm. Sat, 1pm. Sun, 24h.
else if ((weekDay >= 1 && weekDay <= 5 && hour == 18) ||
(weekDay == 7 && hour == 13) ||
weekDay == 7) {
shopCamera();
}
}
function shopCamera() {
action_zone.location ='http://'+IPandPort+'/'+'decoder_control.cgi?user='+user+'&pwd='+pwd+'&command='+shopPreset;
}
function postOfficeCamera() {
action_zone.location ='http://'+IPandPort+'/'+'decoder_control.cgi?user='+user+'&pwd='+pwd+'&command='+poPreset;
}
