Adding a DOT (.) to Regular Expression

Question

I\'m looking to add a (.) to the allowed characters in my function below:

$(id).bind(\'keypress\', function(event) {
    var regex = new RegExp(\"[(         


        

Answer 1

Note that - should either be at the beginning or at the end of character class or has to be escaped by a backslash \, since it indicates range as in a-z

/[()a-zA-Z0-9 ?,/.-]/

Also, if dynamic regex is required, just use the regex literal as in above, if not you'd have to remove the delimiters / / and use the actual regex [()a-zA-Z0-9 ?,/.-] as a String which can be used in RegExp constructor.
