0Wecker LogoPHP / JavaScript einen PC zu wecken Ferne

Veröffentlicht durch & abgelegt unter Web-Technologien. Letzte Aktualisierung .

ich habe ein HTPC and a net­work serv­er on my net­work. My serv­er is always on, aber die HTPC sleeps when it is not in use. If I want to sched­ule record­ings remotely I need a way to wake the HTPC.  The solu­tion I came up with is to provide a webpage on my serv­er (pass­word pro­tec­ted) dass wacht der HTPC and then redir­ects to the web inter­face of the remote con­trol app of the HTPC.  Below is the code for any­one interested…

[php language=“htmlscript”]<html>
<Kopf>
<meta http-equiv=‘refresh’ content=’11;url=address of htpc here’ />
<script type=“text/javascript”>
// time is the num­ber of seconds left
// name is the text part of the con­tain­er to insert count­down in
// num is the unique id of the con­tain­er. Allows for more than 1 per page
func­tion countdown(Zeit, Name, num)
{
// grab the ele­ment object of the count­down container
count­down­Div = document.getElementById(name + num);
// cal­cu­late num­ber of minutes from the seconds
minutes = Math.floor(time / 60);
// remainder is num­ber of seconds
seconds = time % 60;
// add the cur­rent count­down dis­play to the con­tain­er specified
countdownDiv.innerHTML = ‘after ’ + Sekunden + ’ seconds, please wait’;
wenn(time == 1)countdownDiv.innerHTML = ‘after ’ + Sekunden + ’ second, please wait’;
// if time is up remove the edit div, oth­er­wise repeat every second
wenn(Zeit <= 0) countdownDiv.innerHTML = ‘now…’;
else setTimeout(‘countdown(‘ + –time + ‘,“ ‘ + Name + ’ ”,“ ‘ + num + ‘”);‘, 1000);
}
</Skript>
