Programming is fun and interesting. As you all know, sometime we programmers stucks in the middle way of coding without getting a solution. Blogs like this will help us to find a path to solve our problems. The contents of this blog are the solutions that I found by myself and from other sources. Sharing such solutions is also interesting. Thank you!

Random Number Between 2 Double Numbers
Get the time difference between two datetimes [Solved]
var now = "04/09/2013 15:00:00";
var then = "04/09/2013 14:20:30";
moment.utc(moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"))).format("HH:mm:ss")
// outputs: "00:39:30"
But be aware that if you have 24 hours or more, the hours will reset to zero.
If you want to get a valid response for durations of 24 hours or greater, then you'll have to do something like this instead:
Note that I'm using the utc time as a shortcut. You could pull out
var now = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";
var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = Math.floor(d.asHours()) + moment.utc(ms).format(":mm:ss");
// outputs: "48:39:30"
Note that I'm using the utc time as a shortcut. You could pull out
d.minutes() and d.seconds()separately, but you would also have to zeropad them.JavaScript to change the opacity for an element
<html>
<body>
<p id="p1">Select a value from the list below, to change this element's opacity!</p>
<select onchange="myFunction(this);" size="5">
<option>0
<option>0.2
<option>0.5
<option>0.8
<option selected="selected">1
</select>
<script>
function myFunction(x) {
// Return the text of the selected option
var opacity = x.options[x.selectedIndex].text;
var el = document.getElementById("p1");
if (el.style.opacity !== undefined) {
el.style.opacity = opacity;
} else {
alert("Your browser doesn't support this example!");
}
}
</script>
</body>
</html>

Assuming
StartDate and EndDate are of type DateTime:(EndDate - StartDate).TotalDays
