Create a form container with Angular JS component

There are two basic problems need to be solved in your form container:

• Dynamic template for your form

• Handle summit should be run outside of your component.

I solve two problems by

• Read template via attrs property

• Pass handler function as a binding property

Code for form component:

  angular.module('MyApp').component('myForm', {
    templateUrl: function($element, $attrs) {
      return $attrs.template; // read template file from component attribute
    },
    controller: MyFormController,
    bindings: {
      label: '@',
      summitHandler: '&' // call to function outside of component via this property
    }
  });

In MyFormController, we need handle summit event by calling to summitHandler function passed via binding property:

function MyFormController($scope, $element, $attrs) {
      var ctrl = this;
      ctrl.summitForm = function(data) {
        // call handler with data summited
        var handler = ctrl.summitHandler();
        handler(data);
      }
}

That all for our form container component.

Now you can add my-form with:

<my-form label="Personal Info" template="myForm.html" summit-handler="ctrl.myFormHandler"></my-form>

Property ctrl.myFormHandler will be a function handling event in myCtl with:

ctrl.myFormHandler = function(data){
    console.log('receive test summit:' + data);
    ctrl.dataReceived = data;
}

See it run here in Plunk.

Typing in the age field, you can see it will be passed to outside of form. Extend it with more features as you want.
