Form.prototype

How to
Registering new inputs
You will probably want to create new inputs to fit your needs.
You can easily do so by creating a subclass of riotForm.BaseInput and registering it as follow.
With ES5
// ES5
var riotForm = require('riot-form')
var MyInput = riotForm.BaseInput.extend({
myFunc: function () {
return 'whatever you want'
}
})
MyInput.type = 'my-type'
MyInput.defaultTag = 'my-tag'
riotForm.inputFactory.register(MyInput)or with ES6
// ES6
import {BaseInput, inputFactory} from 'riot-form'
class MyInput extends BaseInput {
myFunc() {
return 'whatever you want'
}
}
MyInput.type = 'my-type'
MyInput.defaultTag = 'my-tag'
inputFactory.register(MyInput)
