Javascript: How to replace all "\" character to ""

Question

I try to replace "\" character to empty "" but I can't do it. How to solve it?

Here is my code

abc = abc.replace('\','');

What about marking the answer of @Tim as the right one if it does solve the problem? — lin, Feb 15 '17 at 10:42

to replace all occurrences in a string you need to use a regex with the g flag,

abc = abc.replace(/\\/g, '');

I think you need to escape the backslash:

abc = abc.replace('\\', '');

If you want to replace all occurrences, you can try:

var pattern = '\\\\';
var re = new RegExp(pattern, 'g');
abc = abc.replace(re, '');

@AbdennourTOUMI I updated my answer to cover replace all. – Tim Biegeleisen Sep 23 '16 at 02:37

If you are using `RegExp`, then you have to double escape the ``\``: `'\\\\'`. That's because `new RegExp('\\', 'g');` is equivalent to `/\/g` which is invalid. Currently your coed throws a SyntaxError. – Felix Kling Sep 23 '16 at 03:19
@FelixKling Code is not spelled `coed`. A `coed` typically throws sorority parties, not syntax errors :-) – Tim Biegeleisen Sep 23 '16 at 03:44
