Question

我正在关注angular.io的Angular2快速入门指南他们利用systemJs进行app加载。

angular2，rx.js和angular2.dev.js通过脚本引用加载而不是导入..

无论如何都要导入这些脚本吗？

class PurchaseEntry(tk.Frame):
    def __init__(self, parent, controller):
       tk.Frame.__init__(self, parent)
       self.controller = controller
       PurchaseEntry.configure(self, bg='white')

       label = ttk.Label(self, text='Purchase Entry', font=LARGE_FONT2)
       label.grid(row=0, columnspan=3, sticky='w')

       purchase_entry = ttk.Label(self, text='Purchase Entry:')
       purchase_entry.grid(row=1, column=0)

       self.entry_val = tk.StringVar()
       self.entry_1 = ttk.Entry(self, width=100, textvariable=self.entry_val)
       self.entry_1.grid(row=1, column=2, columnspan=2, sticky='w')
       self.entry_1.focus()

       self.entry_btn = ttk.Button(self,text='Enter', command=self.insert_value)
       self.entry_btn.grid(row=1, column=4, columnspan=2, sticky='w')

       self.chat1 = ttk.Treeview(self)

       chat1 = ttk.Treeview( self, height=28, columns=('dose', 'date   modified'), selectmode="extended")
       chat1.heading('#0', text='item', anchor=tk.CENTER)
       chat1.heading('#1', text='dose', anchor=tk.CENTER)
       chat1.heading('#2', text='date modified', anchor=tk.CENTER)
       chat1.column('#1', stretch=tk.YES, minwidth=50, width=100)
       chat1.column('#2', stretch=tk.YES, minwidth=50, width=120)
       chat1.column('#0', stretch=tk.YES, minwidth=50, width=400)
       chat1.grid(row=2, column=2, columnspan=4, sticky='nsew')

    def insert_value(self):
       value = self.entry_val.get()
       # Inserts data written in the entry box to the treeview widget when Enter button is pressed.
       # Clears the Entry box, ready for another data entry.
       self.entry_1.delete(0, 'end')
       self.chat1.insert('WHAT SHOULD I GIVE AS AN ARGUMENT?')

包含Angular2包使用System.register方法直接注册其包。

那就是说你也可以使用以下配置配置SystemJS来为每个模块的文件加载Angular2文件，但效率较低：

<script src="node_modules/es6-promise/dist/es6-promise.js"></script>
<script src="node_modules/es6-shim/es6-shim.js"></script>

<script src="node_modules/angular2/bundles/angular2-polyfills.min.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>

<script>
  System.config({
    defaultJSExtensions: true,
    map: {
      angular2: 'node_modules/angular2/src',
      rxjs: 'node_modules/rxjs'
    },
    packages: {
      app: {
        defaultExtension: 'js',
        format: 'register'
      },
      angular2: {
        defaultExtension: 'js',
      }
    }
  });
  (...)
</script>

在这两种情况下，都可以在应用程序中导入相应的模块（angular2/*，rxjs/*）。

使用systemJs加载angular2库
