javascript replace characters

Question

I want to replace all occurent of "-", ":" characters and spaces from a string that appears in this format:

"YYYY-MM-DD HH:MM:SS"

something like:

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

Answer 1

You were close: "YYYY-MM-DD HH:MM:SS".replace(/:|-/g, "")

Answer 2

/:-/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, "");
