JavaScript用字符替换字符串|

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?

Answer 1

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.

Answer 2

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

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

Answer 3

是不是

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

Answer 4

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, "")
