Time Related Hyperlinks 1

[NoviceJavaUser]

Hi,

Hope this is a simple answer.

Basically, i have 1 hyperlink, and dependant upon the time of day i want it to go to different pages, for example

between 0800 and 2100 hyperlink goes to page A
between 2101 and 0759 hyperlink goes to page B

Any ideas???

If you have a server side script then simply show the link based on the time - if not you can have a buffer page that is always linked to and based on finding the time with javascript location.replace() the correct page...

The problem with using client-side scripting to find the time is that the viewer's clock can be off. I worked on one computer where the clock was off by over a year, plus wrong day and wrong time of day. I discovered it when trying to update Norton virus definitions that they'd paid for online, and the key didn't work. I finally totally deleted Norton and reinstalled, and when I looked at how long the 1-year subscription was good for, the date was over 3 years in the future.

With Windows XP and the automatic update to the time enabled, that will become less and less of a problem as the older operating systems fall by the wayside.

It has to be client side, and it is not a problem to use the Users PC's Time as it is a small business network that the web page will be located on, so not a problem with the system time being out.

Over the internet, you'd have to do it server-side - because it's a world-wide web, and when it's 21:00 for you it isn't necessarily the same time for me.

Since you're working on an intranet, you don;t have to worry about multiple timezones. You also don't have to worry about users having Javascript switched off or about accessibility to search engines.

You can therefore use Javascript to pick the page on the client side. It should be fairly simple. Something like this? ...

<script language="Javascript">
function pickpage () {
   var now = new Date();
   var time = (now.getHours() * 100) + now.getMinutes() ;
   var dest = "pageB.htm";
   if (time >= 800 && time <= 2100) dest="pageA.htm";
   window.location = dest;
}
</script>

<a href="javascript:pickpage()">Timed Link</a>

AH!! Sorry... as an afterthought, i need different times of a weekend so for example Mon -Fri 0800 - 2100 Sat & Sun 1000 - 2000hrs
Is this anymore difficult? Sorry, i really am quite new to Java script :-(

Chessbot's right, you should really be asking these questions in the Javascript forum. However, to keep the thread together, try this:

function pickpage () {
   var now = new Date();
   var time = (now.getHours() * 100) + now.getMinutes() ;
   var weekday = now.getDay();
   var dest = "pageB.htm";
   if (weekday > 0 && weekday < 6)  {
     if (time >= 800 && time <= 2100) dest="pageA.htm";
   } else {
     if (time >= 1000 && time <= 2000) dest="pageA.htm";
   }
   window.location = dest;
}
