Replace '\' with '-' in a string

Question

I have seen all the questions asked previously but it didn't help me out . I have a string that contains backslash and i want to replace the backslashes with '-'

var s="adbc\sjhf\fkjfh\af";
s = s.replace(/\\/g,'-');
alert(s);

I thought this is the proper way to do it and of course i am wrong because in alert it shows adbcsjhffkjfhaf but i need it to be like adbc-sjhf-fkjfh-af.

What mistake i do here and what is the reason for it and how to achieve this...??

Answer 1

Your s is initially adbcsjhffkjfhaf. You meant

var s="adbc\\sjhf\\fkjfh\\af";

Answer 2

You need to double-up the backslashes in your input string:

var s="adbc\\sjhf\\fkjfh\\af";

Prefixing a character with '\' in a string literal gives special meaning to that character (eg '\t' means a tab character). If you want to actually include a '\' in your string you must escape it with a second backslash: '\\'

Answer 3

Javascript is ignoring the \ in \s \f \a in your string. Do a console.log(s) after assigning, you will understand.

You need to escape \ with \\. Like: "adbc\\sjhf\\fkjfh\\af"

Answer 4

The string doesn't contain a backslash, it contains the \a, \s and \f (escape sequence for Form Feed).

if you change your string to adbc\\sjhf\\fkjfh\\af

var s="adbc\\sjhf\\fkjfh\\af";
s = s.replace(/\\/g,'-');
alert(s);

you will be able to replace it with -
