The backslash has to be escaped.

string = string.split("\\");

In JavaScript, the backslash is used to escape special characters, such as newlines (\n). If you want to use a literal backslash, a double backslash has to be used.

So, if you want to match two backslashes, four backslashes has to be used. For example,alert("\\\\") will show a dialog containing two backslashes.
