Question

So I’ve been playing around with the replace function (method?) in js.

$get('msgBar').replace(/+/g,' ');

Let’s say the content of $get(‘msgBar’) is “Welcome+back+now”.

replace('+',' ') would only replace the first +, and not the second.

replace(/+/g,' ') crashes

replace(/"+"/g,' ') and replace(/\+/g,' ') are both the same as the first

I’m sure the solution is easy… 🙂

Answer 1

You must quote +:

$get('msgBar').replace(/\+/g,' ');

‘+’ is a meta character, like ‘*’. It means “one more repetitions”. It you literally want ‘+’ , then you have to quote it with the backslash.
