changing a variable in a string javascript

Question

I have a string looking like: some+thing+-+More

How do i replace the + sign?

I have tried the following without success:

temps = "some+thing+-+More";
temps = temps.replace("/+" /g, "blank");
temps = temps.replace("+" /g, "blank");
temps = temps.replace(/+/g, "blank");

• Mike Samuel: A character set will do it: /[+]/g or you can just escape it: /\+/g.
• pimvdb: Note that "/+" actually has a different meaning - namely just these two characters. The escape character in JavaScript is \.

Answer 1

You need to escape the plus sign with a backslash, like so:

var temps ="some+thing+-+More";
temps = temps.replace(/\+/g, "blank");

Answer 2

"+ + + +".replace(/\+/g, "blank")

This results:

"blank blank blank blank"

You should use the escape char:

temps = temps.replace(/\+/g, "blank");

Answer 3

temps = temps.replace(/\+/g, "blank");

Answer 4

Thanks Jonathan.

I took a different approach: I figure out the Hex number for + sign was 2B So....

temps = temps = temps.replace(/\x2B/g, "blank"); 

also did the trick!

• Jonathan Fingland: This is actually a really good technique for lots of other situations. \x for the hex value and \u for unicode. For the OP's case it is a bit overkill but most developers should be aware of this none the less.
