Regex to allow spaces in alphanumeric

I have this here:

$("#MyInputBox").keypress(function (e) {
  if (e.charCode != 0) {
    var regex = new RegExp("^[a-zA-Z0-9\-\s]+$");
    var key = String.fromCharCode(!e.charCode ? e.which : e.charCode);
    if (!regex.test(key)) {
      e.preventDefault();
      return false;
    }
  }
});

Problem is, it does not allow me to enter a space. I WANT it to allow a space. Everything else works fine (i.e I can enter numbers, letters, dash... but not a space.)

You must escape the backslash before the s

var regex = new RegExp("^[a-zA-Z0-9\\-\\s]+$");

or ommit the constructor:

var regex = /^[a-zA-Z0-9\-\s]+$/
