Since jquery-validation 1.15.0 a cleaner approach is to use the normalizer callback:

$( "#myform" ).validate( {
  rules: {
    field: {
      required: true,
      normalizer: function( value ) {
        return $.trim( value );
      }
    }
  }
} );

The normalizer (immutably) transforms the value before the validation takes place.

See the Normalizer Docs for more details.
