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.

Answer 2

我相信这应该做到：

str.replace(/[.,\s]/g, '');

Answer 3

像这样的东西应该工作......

str=str.replace(/./g,'').replace(/,/g,'').replace(/ /g,'');
