title: How to allow only defined characters as input using jQuery?
body: <p>How do i allow special characters such as hyphen,comma,slash,space key,backspace key,delete key along with alphanumeric values and restrict the rest in jQuery?</p>
  
  <p>As this criteria(allowed characters/input values) varies from field to field, i would like to make it as a utility method which accepts input field id and allowed characters as parameters.
  for example: limitCharacters(textid, pattern)</p>
