When using / in a /.../ regex syntax you need to escape it with a backslash. Alternatively you can use the RegExp constructor to avoid having to escape the / : both /[^\/]/ and new RegExp("[^/]") will match any character but /.

To remove any special character but /, it depends on what you call a special character but I would use /[^a-zA-Z0-9\/]/.
If you don't mind underscores you can use /[^\w\/]/.

It matches only one character, so you will probably want to use the g global flag : /[^a-zA-Z0-9\/]/g or new RegExp("[^a-zA-Z0-9/]", "g")

Try this as well

input.replace(/\W/g, function(match){ return (match == "/" ? match : "") });


function replaceExceptChar( input, specialChar )
{
   return   input.replace(/\W/g, function(match){ return (match == specialChar ? match : "") });
}

console.log( replaceExceptChar("asdasd2323(*(&*/", "/") );
