Removing backslashes from strings in javascript

Question

I have a url in this format:

http:\/\/example.example.ru\/u82651140\/audio\/song.mp3

How can I remove the extra "\"s from the string? I have tried string.replace("\","") but that does not seem to do anything. If you could give me a JavaScript regular expression that will catch this, that would also work too. I just need to be able capture this string when it is inside another string.

Solution 1

Try:

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

This will specifically match the "\/" pattern so that you don't unintentionally remove any other backslashes that there may be in the URL (e.g. in the hash part).

Solution 2

Try

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

Solution 3

from: http://knowledge-serve.blogspot.com/2012/08/javascript-remove-all-backslash-from.html

function replaceAllBackSlash(targetStr){
    var index=targetStr.indexOf("\\");
    while(index >= 0){
        targetStr=targetStr.replace("\\","");
        index=targetStr.indexOf("\\");
    }
    return targetStr;
}

This does not fork if there is /" inside the string @Ates Goral

Does not work: try the string "corp\thomas". Will remove "\t".

@TomaszPlonka You might be getting the impression that it's removing it because \t is the escape sequence for the tab character.

@alper Can you be more specific? Do you mean "/\""?

[alper]

I believe I meant the string we want to replace contains /" your answer does not work

@alper The question and my answer was about removing backslashes and nothing else. Can you give an example of the full string?

@alper /"hello/" is not valid JS. I'm confused.

@alper We're trying to remove backslashes (\) though. This is a forward slash: /.

ah sorry for misguiding
