JS Special Character Valitation

I am attempting to include [ ] $ ? \ in the below snippet. I tried to escape them to no avail. What is the proper syntax for this string?

function validate_desc(val){
        if ( val.match("^[a-zA-Z0-9,-. \\\\/(/)#/_/'\":]+\$") ) {
            return true;
        } else {
            return false;
        }
    }

Check this:

function validate_desc(val){
      var inv = val.match(/[^\w\,\-\.\ \\\/\(\)\#\'\"\:]/g);
        if ( inv ) {
         console.log("Invalid chars: "+inv.join(' '));
            return false;
        } else {
            return true;
        }
    }
