TypeError: $(...).getValue 不是一个函数

Question

I have this Alpaca form
I would like to get the content of the form (the values the user enters)
so I found an example on alpaca site
The example is working fine when the button is inside this.getValue(); is working fine
But from outside I am getting TypeError: $(...).getValue is not a function
What am I doing wrong?

 $("#field1").alpaca({ "data": { "firstName": "John", "lastName": "McClane" }, "schema": { "type": "object", "properties": { "firstName": { "type": "string", "title": "First Name" }, "lastName": { "type": "string", "title": "Last Name" } } }, "options": { "form": { "buttons": { "submit": { "title": "Serialize - working fine....", "click": function() { var value = this.getValue(); alert(JSON.stringify(value, null, " ")); } } } } } });

Answer 1

You should add alpaca() between $('#field1') and getValue()

JSON.stringify($('#field1').alpaca().getValue()

Here's a fiddle for that.
