javascript - ES6——导入es5文件

Question

我尝试使用此 ( https://github.com/gocardless/es6-angularjs/blob/master/README.md) 作为起点，然后包括 bootstrap javascript 代码。为了打开模态

但唯一发生的事情是:

Potentially unhandled rejection [3] Error loading "components/bootstrap/dist/js" at http://localhost:3010/components/bootstrap/dist/js.js
Error loading "components/bootstrap/dist/js" from "app-compiled/bootstrap" at http://localhost:3010/app-compiled/bootstrap.js
Not Found: http://localhost:3010/components/bootstrap/dist/js.js (WARNING: non-Error used)

我将其添加到 main.js 中:

import 'bootstrap-js';
//TODO please explain to me why not working

并将此添加到 loader.config.js 文件:

System.config({
  meta: {

    ...,
    'components/bootstrap/dist/js':{ format: 'global', export: 'bootstrap'}


  },
  map: {

    ....,
    'bootstrap-js': 'components/bootstrap/dist/js'

  }
});

Answer 1

1. 在此处尝试使用exports 而不是export:

System.config({
    meta: {
    //...
        'components/bootstrap/dist/js':{ format: 'global', exports: 'bootstrap'}
    }
    //...
});

1. 当您编写 { format: 'global', exports: 'bootstrap'} 时，您正在尝试获取全局 bootstrap 变量。但这样的并不存在。所以我认为你必须删除元线并修复 map 。结果必须如下所示:

System.config({
    meta: {
        //...
        'components/path/to/jquery': { format: 'global', exports: 'jQuery' },
        'components/bootstrap/dist/js/bootstrap': { deps: ['jquery'] }
    }
    map: {
        //...
        'jquery': 'components/path/to/jquery',
        'bootstrap-js': 'components/bootstrap/dist/js/bootstrap'
    }
});
