How to replace all occurrences of a string in JavaScript? 41 answers

这是一个不需要regex的选择：

var str = 'a b c';
var replaced = str.split(' ').join('+');

You need the /g (global) option, like this:

var replaced = str.replace(/ /g, '+');

You can give it a try here. Unlike most other languages, JavaScript, by default, only replaces the first occurrence.

var str = 'a b c';
var replaced = str.replace(/s/g, '+');
