Question

I’m coding a ‘Connect to Meeting’ page where i would like the link that allows attendees to join our GoToMeeting event to ‘become active’ 15 minutes prior to the start time.

So the page users visit to see the connection info (meetingID, password) includes the start time of the meeting. I need a button (‘Connect To Meeting’) to change from inactive to Active when
[Now() < (StartTime()-15minutes)].

Answer 1

If you just need the button to change, calculate the difference between now() and your start time and create a settimeout with that value.

var now = new Date();
var start = new Date(2010,5,27,11,30,0); // starts at 11:30am
var diff = start.getMilliseconds() - now.getMilliseconds();
window.setTimeout("document.getElementById('button').disabled = false;",diff);
