JavaScript Replace String with a Character |

Question

when I try the following it doesn't work: str.replace("| stuff", "")

But if I remove the PIPE it does? str.replace("stuff", "")

Why doesn't the JS function allow for the PIPE | ? What can I do to do a replace that includes a pipe?

what is str, what is your result, and what are you trying to achieve? — peller

Because .replace accepts a RegExp, and | is a special character in RegExp. You need to escape it.

For example, use str.replace(/\|/g, "") to remove every | character.

Thanks but I want to replace the following String " | stuff" There will just be one pipe, how can I replace both?

a regexp was not used in the example in the question, so no need to escape it

No, it should be working, unless you use /| stuff/ or RegExp("| stuff") instead of "| stuff"

"xyz| stuff".replace("| stuff", ""); //returns xyz

+1 You are absolutely right. I should have tested before answering.

@S.Mark, just tested it and it works in IE6+, Firefox 2.0+, Chrome and Safari.

str.replace("| stuff", "") should work but will only replace the first occurrence. If you want to replace all of them, try a using a regex like str.replace(/\|\sstuff/g, "")

Or just str.replace(/\| stuff/g, ""), but the \s makes it work for any whitespace character
