Replace Multiple String at Once With Regex in Javascript

Question

I tried this : Replace multiple strings at once And this : javascript replace globally with array how ever they are not working.

Can I do similar to this (its PHP):<

Answer 1

One possible solution:

var a = ['a','o','e'],
    b = ['1','2','3'];

'stackoverflow'.replace(new RegExp(a.join('|'), 'g'), function(c) {
    return b[a.indexOf(c)];
});

As per the comment from @Stephen M. Harris, here is another more fool-proof solution:

'stackoverflow'.replace(new RegExp(a.map(function(x) {
    return x.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
}).join('|'), 'g'), function(c) {
    return b[a.indexOf(c)];
});

N.B.: Check the browser compatibility for indexOf method and use polyfill if required.
