Jquery- backslash character

Question

I am having a problem trying to replace the backslash character from a string:

var g = myReadString;
g = g.replace("\", "\\\\");

it is giving an error of unrecognized character.

How could a simple \ be replaced with four \\\\?

I would appreciate any help, thanks. Pandy

Answer 1

The \‍ is the begin of an escape sequence. If you mean to write \‍ literally, you need to write \\ that is an escape sequence as well and will be interpreted as a single \‍. So if you want to replace one \‍ by four \\\\, you need to write this:

g.replace("\\", "\\\\\\\\")

But this will only replace the first occurrence of a single \‍. To do a global replace you need to use a regular expression with the global match modifier:

g.replace(/\\/g, "\\\\\\\\")
