promise“ then”函数内部的aurelia视图模型属性

Question

I'm trying to access my view-model properties and bindings into a "then" function of a promise just like this :

let that = this;
this.getDate().then(data => {
    that.binding.style.backgroundColor = "white";
    console.log(that.property);
});

The thing is "this" is undefined so how am I supposed to get those?

当我应该尝试读取的变量是_this5时，我的错误是试图在调试器中读取“ this”，该变量是由babel transpiller为ES5创建的。
