JavaScript remove fullstop, comma and spaces from a string

Question

I'm trying to remove the fullstops, commas and spaces from a string. I'm pretty sure I have to do this using this: str.replace(<some Regex here>, "");

I'm just not very familiar with Regex, how can I accomplish this?

Answer 1

Use this regex /[.,\s]/g

var str = 'abc abc a, .aa ';

var regex = /[.,\s]/g;

var result = str.replace(regex, '');

document.write(result);

You don't need to escape character except ^-]\ in character class []

Any character except ^-]\ add that character to the possible matches for the character class.
