win-universal-app - Windows 10 应用预启动 winjs

Question

随着 2015 年 11 月 18 日的新更新。Windows 应用程序认证工具包正在检查预发布测试，我尝试使用此示例

但是，力求为 WinJS 找到一个示例。如何在 WinJS 应用程序中执行此操作？

您应该检查功能args.detail.prelaunchActivated。app.onactivated以下代码是从 Visual Studio 2015 Update 1 构建的模板更新而来，并已参考 C++/C# 的模板

默认.js

// For an introduction to the Blank template, see the following documentation:
// http://go.microsoft.com/fwlink/?LinkId=232509
(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) {
                // 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.
            }

            if (!args.detail.prelaunchActivated) {
                // TODO: This is not a prelaunch activation. Perform operations which
                // assume that the user explicitly launched the app such as updating
                // the online presence of the user on a social network, updating a 
                // what's new feed, etc.
            }

            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();
})();
