Remove all except alphanumeric spaces

advertisements

I have a string that has some special characters and spaces. I can remove the special characters, but how can I make it so it keeps the spaces?

var a = "dent's dc^e co cbs";

var re = /\W/g;

b = a.replace(re, '');

console.log(b);

The way it is, it just deletes everything. And it broke when I tried to add (^\s) after the W

You can use negated character class with \w, and \s:

var re = /[^\w ]/g;
  • [^\w] gives you same effect as \W
  • Addition of an empty space " " in negated character class, also negates space.
