jquery.validate plugin - how to trim values before form validation

Question

I\'m using the excellent jquery.validation plugin by Jörn Zaefferer and I was wondering whether there\'s a easy way to automatically trim form elements before they are valid

Answer 1

When downloading validator.js, there is a file called additional-methods.js that contains the method "nowhitespace" and "lettersonly" that will strip out any white space in a field.

rules: {
  user_name: {
    required: true,
    minlength: 3,
    nowhitespace: true
  }
}
