How to replace all \ char into ' in javascript

Question

if, a = "Bob\\'s house"

how would you replace the backslash with another ' ? I want a to equal "Bob''s house"

I would assume that I can do a.replace("\\", "'") but this doesn't work

Answer 1

It does not work because \\' is treated as a single character. In Javascript \\ is used to initiate an escape character, which means "literally the character after \\".

In order to show \\ you therefore need to write \\\\ . And if you want to change escaped ' into '' what you need to do is simply a.replace("\\'", "\\'\\'") ;

Answer 2

basically a = "Bob\\'s house" is interpreted as "Bob's house" , youre just escaping the ' . there is no backslash in the string.

to have your wanted result ( "Bob''s house" ), simply do the following:

a.replace("\'", "\'\'")

Answer 3

正如user2182349所说， a.repalce("\\\\", "'")
