Replace all spaces in a string with '+' [duplicate]

Question

I have a string that contains multiple spaces. I want to replace these with a plus symbol. I thought I could use

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

but it only replaces the first occurrence. How can I get it replace all occurrences?

Answer 1

Here's an alternative that doesn't require regex:

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