如果我有a itemViewModel.html和a itemViewModel.js,它们都会成功加载.但是,如何访问绑定模型itemViewModel.js?
我试过用了bindable.
import {bindable, bindingMode} from 'aurelia-framework';
export class ItemViewModel {
@bindable model;
constructor() {
console.log("using bindable", this);
}
}

这可能吗?
<compose model.bind="item"将activate(model)在您的viewmodel中调用一个方法并为您提供item.
// the model received here is the *item* from the above <compose
activate(model){
this.model = model;
}

如果你想在绑定中传递多个模型,你可以做到
<compose model.bind="{item: item, value: value}"

然后你得到:
activate(model){
this.item = model.item;
this.value = model.value;
}
