Hi,
I'm building a dashboard with a DateRangeFilter in it. I also have two
buttons, labeled Today and Yesterday that set the range of the
DateRangeFilter with code like this:
var today = new Date();
today.setHours(0, 0, 0, 0);
const dayLength = 24 * 60 * 60 * 1000;
switch (buttonSelection)
{
case 'today' :
dateRangeSlider.setState({lowValue : today, highValue : new
Date(today.getTime() + dayLength)});
break;
case 'yesterday' :
var yesterday = new Date(today.getTime() - dayLength);
dateRangeSlider.setState({lowValue : yesterday, highValue :
today});
break;
}
dateRangeSlider.draw();
But when it runs, the range ends up including two days. E.g. if it's 9/6
and I click 'Today', the range shows 9/5 through 9/7; if I click
'Yesterday', the range becomes 9/4 through 9/6.
If I step through the code, after the call to setState, the lowValue is
9/6/2014 00:00:00 and the highValue is 9/7/2014 00:00:00 - so far, so good.
But after the call to draw(), lowValue is 9/5/2014 01:00:00 and highValue
is 9/7/2014 01:00:00. I can understand that some of this might be Daylight
Saving Time related: midnight becoming 1 AM. But why would 9/6/2014 00:00
change to 9/5/2014 01:00?
Plus, this isn't quite what I want. Since the high and low values are
inclusive, for Yesterday I don't want 9/5 00:00 through 9/6 00:00: I want
9/5 00:00 through 9/5 23:59:59. But if I set that, DateRangeFilter changes
9/5 23:59:59 to 9/6 01:00:00.
Am I doing something wrong, or are these bugs in DateRangeFilter? If the
latter, is there a workaround?
Thanks,
Bob
