Question

我无法弄清楚如何让我的winjs（react-winjs）应用程序使用硬件后退按钮。这是我的导航功能的一个例子：

handleNavigation(location) {
    this.setState({
        location: location
    });

    WinJS.Navigation.navigate(`/${location}`);
    console.log(WinJS.Navigation.history);
}

console.log(WinJS.Navigation.history)输出正确的数组，称为＆＃34; backStack＆＃34;使用正确的历史记录顺序，但单击Windows手机模拟器上的硬件后退按钮只是退出应用程序。

我错过了一些明显的东西吗？

这是我设法找到并尝试但没有成功（我确实为C＃找到了一些好的文档，但是我不需要的是什么）：

确实这是一个非常愚蠢的错误，我在没有等待winjs / windows准备好的情况下初始化我的应用程序，这就是我应该如何启动它：

Set-Cookie

这样我可以将addEventListener添加到我的组件componentWillMount函数中的“backclick”，它可以工作：

(function () {
"use strict";

var app = WinJS.Application;
var activation = Windows.ApplicationModel.Activation;

app.onactivated = function (args) {
    if (args.detail.kind === activation.ActivationKind.launch) {
        if (args.detail.previousExecutionState !== activation.ApplicationExecutionState.terminated) {
            // This is how you should initialize your app
            ReactDOM.render(<App />, document.getElementById('app'));
        } else {
            // TODO: This application was suspended and then terminated.
            // To create a smooth user experience, restore application state here so that it looks like the app never stopped running.
        }
        args.setPromise(WinJS.UI.processAll());
    }
};

app.oncheckpoint = function (args) {
    // TODO: This application is about to be suspended. Save any state that needs to persist across suspensions here.
    // You might use the WinJS.Application.sessionState object, which is automatically saved and restored across suspension.
    // If you need to complete an asynchronous operation before your application is suspended, call args.setPromise().
};

app.start();
})();
