Get difference between 2 dates in JavaScript? [duplicate]
...(), b.getDate());
return Math.floor((utc2 - utc1) / _MS_PER_DAY);
}
// test it
const a = new Date("2017-01-01"),
b = new Date("2017-07-25"),
difference = dateDiffInDays(a, b);
This works because UTC time never observes DST. See Does UTC observe daylight saving time?
p.s. After discuss...

...oth;
}
This solution appears to be backward compatible to IE5.5 but is untested.
Solution 3:
It's also possible to set display: inline-block; and width: 100%; to emulate a normal block element while not collapsing.
Demo: http://jsfiddle.net/SO_AMK/ae5ey/
CSS:
.clearfix {
display: inline-...
Is it necessary to write HEAD, BODY and HTML tags?
...t convenient to omit the tags when prototyping and especially when writing test cases as it helps keep the mark-up focused on the test in question. The inference process should create the elements in exactly the manner that you see in Firebug, and browsers are pretty consistent in doing that.
But.....
How can I check if a scrollbar is visible?
...r(); // returns true if there's a `vertical` scrollbar, false otherwise..
tested working on Firefox, Chrome, IE6,7,8
but not working properly on body tag selector
demo
Edit
I found out that when you have horizontal scrollbar that causes vertical scrollbar to appear, this function does not work.......
Convert string to variable name in JavaScript
...
@goggin You should regex-test the argument to make sure that it's a valid name. Just evaling the argument without checking it first is ridiculously insecure.

Flushing footer to bottom of the page, twitter bootstrap
...dn't take trips to stack exchange, multiple gist revisions, cross-browswer testing, and eventual surrender to a simple JS trick. Yeah, I feel a bit dirty, but at least it works.

Generic type conversion FROM string

I can attest that it works in my feeble asteroids clone, and seems to deal correctly with the edge cases described in other answers by Elemental, Dan and Wodzu. It's also probably faster than the code posted by KingNestor because it'...
