I am trying to create a Progress bar styled timeline that takes 3 dates, and builds a progress bar from them. I found a helpful post on here that I used to build the basics of this, but it doesn't do exactly what I'd like.
Simply, I would like for 0% to be 12/01/13, 100% to be 12/25/13, and then the progress bar to display today's date between that. I have setup a progress bar using some javascript to do the countdown, but I'm not sure what it's calculating from, as it's already at like 85%. Since today is the 6th, it should only be ~24%.
^ Demo | Code v
<script type='text/javascript'>
$(function(){
var target = new Date('12/25/2013'),
today = new Date(),
daysToGo = Math.ceil((target.getTime() - today.getTime() ) / (1000*60*60*24)),
percent = 100 - daysToGo;
$("#progressbar").progressbar({
value: percent,
create: function(event, ui) {
$('.ui-progressbar');
}
});
});
</script>
Its your percent calculation that is wrong.
You should do something like:
var percent = 1 - daysToGo/25
25 being 1st dec to 25th december. Now your percent is in decimals, eq 0.24. Multiply this with 100 if you want the percentage.
