Question

How to globally replace a forward slash in a JavaScript string?

Answer 1

Use a regex literal with the g modifier, and escape the forward slash with a backslash so it doesn't clash with the delimiters.

var str = 'some // slashes', replacement = '';
var replaced = str.replace(/\//g, replacement);

Answer 2

This is Christopher Lincolns idea but with correct code:

function replace(str,find,replace){
    if (find != ""){
        str = str.toString();
        var aStr = str.split(find);
        for(var i = 0; i < aStr.length; i++) {
            if (i > 0){
                str = str + replace + aStr[i];
            }else{
                str = aStr[i];
            }
        }
    }
    return str;
}

Example Usage:

var somevariable = replace('//\\\/\/sdfas/\/\/\\\////','\/sdf','replacethis\');

Javascript global string replacement is unecessarily complicated. This function solves that problem. There is probably a small performance impact, but I'm sure its negligable.

Heres an alternative function, looks much cleaner, but is on average about 25 to 20 percent slower than the above function:

function replace(str,find,replace){
    if (find !== ""){
        str = str.toString().split(find).join(replace);
    }
    return str;
}

Answer 3

You can create a RegExp object to make it a bit more readable

str.replace(new RegExp('/'), 'foobar');

If you want to replace all of them add the "g" flag

str.replace(new RegExp('/', 'g'), 'foobar');

Answer 4

This has worked for me in turning "//" into just "/".

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

Answer 5

Is this what you want?

'string with / in it'.replace(/\//g, '\\');

Answer 6

You need to wrap the forward slash to avoid cross browser issues or //commenting out.

str = 'this/that and/if';

var newstr = str.replace(/[/]/g, 'ForwardSlash');
