Regex remove a special and duplicated character from the string in javascript?

Question

I have problem to write a regex to remove a special and duplicated character from a string in javascript. Because I need to compare the date like type of this

2015-11-05-14:30

so I'm going to transform the date string into integer number

201511051430

and make it comparable. And so, I need to remove the character "-" & ":" !

str.replace(/[-:]/g,''); Fiddle

Simply use the following regex

/[-:]/g

OR you can simply use

/\D/g

\D will match any character i.e. not a digit
g for global modifier

Javascript :

str.replace(/[-:]/g,'');

You should probably be converting this into a timestamp instead of a custom "date-ish" number:

> +new Date('2015/11/05 14:30')
1446708600000

You can not only compare this, but your comparisons can be meaningful (e.g. you can figure out how many days apart 2 dates are).

Based on your original format:

var timestamp = +new Date(dateStr.replace(/-(?=\d+:)/, ' ').replace(/-/g, '/'));
