如何在JavaScript中替换加号？

Question

I need to make a replace of a plus sign in a javascript string. there might be multiple occurrence of the plus sign so I did this up until now:

myString= myString.replace(/+/g, "");#

This is however breaking up my javascript and causing glitches. How do you escape a '+' sign in a regular expression?

Answer 1

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

Answer 2

You need to escape the + as its a meta char as follows:

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

Once escaped, + will be treated literally and not as a meta char.

Answer 3

我更喜欢这个：

myString.replace(/[+]/g, '').

Answer 4

你应该逃避你的+号， \\+

Answer 5

myString.replace(/\+/g, "");
