if click validate
we have Uncaught TypeError: $$(…).validate is not a function
Sorry for the inconvenience in our samples/docs, but there’s no predefined validate() method for the html-form.
@Listopad - How do we validate htmlForm then? I have some radio buttons and checkboxes in a htmlform which is loaded from an external source. Thanks
