如何在Barba中使用module.exports

Question

I'm trying to split my barba views into different modules with module.exports.

This is the code i have for the view.

var Barba = require('barba.js');

var HomeView = Barba.BaseView.extend({
  namespace: 'homepage',

  onEnter: function() {

    console.log('intro start home');
      // The new Container is ready and attached to the DOM.
  },
  onEnterCompleted: function() {
      // The Transition has just finished.
      console.log('intro finished home');
  },
  onLeave: function() {
      // A new Transition toward a new page has just started.
      console.log('outro start home');
  },
  onLeaveCompleted: function() {
      // The Container has just been removed from the DOM.
      console.log('outro finished home');

  }
});

HomeView.init();

module.exports = HomeView;

And this is how i am creating the module

var homeView = new HomeView();

The error i keep getting is 'i is not a constructor'. I do this the same way with backbone views and this works.

Answer 1

I believe you should not do var homeView = new HomeView(); , instead import the module and do HomeView.init(); . These barba.js view's doesn't look like constructor functions that you manually initialize, they seem to find elements with matching namespace like

<div class="barba-container" data-namespace="homepage">

and create instances internally. Follow the documentation, it doesn't tell you to do var homeView = new HomeView();

我仅通过导入模块（而不创建新实例）进行拆分，并且可以正常工作：

import  HomeView from './your/path/HomeView'
