JavaScript backslash (\) in variables is causing an error
The backslash (\) is an escape character in Javascript (along with a lot of other C-like languages). This means that when Javascript encounters a backslash, it tries to escape the following character. For instance, \n is a newline character (rather than a backslash followed by the letter n).
In order to output a literal backslash, you need to escape it. That means \\ will output a single backslash (and \\\\ will output two, and so on). The reason "aa ///\" doesn't work is because the backslash escapes the " (which will print a literal quote), and thus your string is not properly terminated. Similarly, "aa ///\\\" won't work, because the last backslash again escapes the quote.
Just remember, for each backslash you want to output, you need to give Javascript two.

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.
