You can use either a character class or an | (or):

var date = "YYYY-MM-DD HH:MM:SS".replace(/[:-\s]/g, '');

var date = "YYYY-MM-DD HH:MM:SS".replace(/:|-|\s/g, '');

The regex you want is probably:

/[\s:-]/g

Example of usage:

"YYY-MM-DD HH:MM:SS".replace(/[\s:-]/g, '');

[] blocks match any of the contained characters.

Within it I added the \s pattern that matches space characters such as a space and a tab \t (not sure if you want tabs and newlines, so i went with tabs and skipped newlines).

It seems you already guessed that you want the global match which allows the regex to keep replacing matches it finds.

/:-/g means ":" followed by "-". If you put the characters in [] it means ":" or "-".

var date = this.value.replace(/[:-]/g, "");

If you want to remove spaces, add \s to the regex.

var date = this.value.replace(/[\s:-]/g, "");
