Because a backslash is used as an escape character, you'll need to escape it:
str = str.replace("\\/", "/");
The above replaces \/ with /. In general, anywhere you use a backslash in a string, you probably need to escape it. So, to replace /\ with /, you'd use:
str = str.replace("/\\", "/");
These will, of course, only replace one instance in the string. To replace multiple instances, use a regular expression with the g (global) modifier:
str = str.replace(/\\\/|\/\\/g, "/")
Here, because forward slashes have meaning as regex terminators, you're having to escape the forward slash as well as the backslash. The alternative is to use the RegExp class:
str = str.replace(new RegExp("\\\\/|/\\\\", "g"), "/")
In this one, you're having to escape the backslash twice — once to escape it in the string, and once in the regex. (Here's a better explanation.)
