How do I use the JavaScript string replace method to replace the '+' sign?

Question

All you need to know is in the question. I have a search query in the URL that looks like this:

http://www.mysite.com?param=word1+word2+word3

So far, I can retrieve "word1+word2+word3" but I can't seem to use something like:

document.write(str.replace(/+/g," "));

I want the final output to look like this: "word1 word2 word3"

Thanks for looking.

Try to escape the + sign using the escape char \ since is a restricted char:

document.write(str.replace(/\+/g," "));

The + is a special character in regex, if you want to match it literally you have to escape it. So try:

document.write(str.replace(/\+/g," "));

You have to escape the + sign, it's has special meaning in Regexes.

document.write(str.replace(/\+/g," "));

How about using the split() function, that seems to be much simpler for this case:

document.write(str.split(",", " ");

Try with the hex value

document.write(str.replace(/[\u002B]/g," "));
