推荐答案

您可以绑定到任何 Javascript 对象.但是您只能在绑定对象上使用属性和属性.所以你不能调用像 getName() 这样的函数.

You can bind to any Javascript object. But you can only use attributes and properties on the bound objects. So you can't call functions like getName().

ManagedObjects 如何处理您在元数据中声明的属性?它创建 getXxx() 和 setXxx() 方法并将数据 xxx 存储在私有对象内的某处.这就是为什么你不能绑定到 {xxx} 即使你已经在 ManagedObject 上声明了一个 xxx 属性.

What do ManagedObjects do with the properties you declared in the metadata? It creates getXxx() and setXxx() methods and stores the data xxx somewhere inside a private object. Thats why you cant bind to {xxx} even though you have declared a xxx property on the ManagedObject.

作为一种解决方法，您可以创建getter 属性 和 setter 属性您要绑定到的所有属性的 ManagedObject:

As a workaround you could create getter properties and setter properties on your ManagedObject for all attributes you want to bind to:

get xxx()  { return this.getXxx();} 
set xxx(value) { this.setXxx(value);}
