如何在Chrome应用中动态更新版本号？

Question

I have a google chrome packaged app and I would like to update the version number on the app's about page based off of its manifest file. 我有一个google chrome打包的应用程序，我想根据清单文件更新该应用程序“关于”页面上的版本号。 My manifest file is like so: 我的清单文件是这样的：

manifest.json manifest.json

{
  "manifest_version": 2,
  "name": "Book Writer",
  "version": "2.0.8.0",
  "icons": {
    "16": "images/Book-icon.png",
    "48": "images/Book-icon.png",
    "128": "images/Book-icon.png"
  },
  "app": {
    "background": {
      "scripts": ["main.js"]
    }
  },
  "permissions": [
    "storage",
    "contextMenus"
    ]
}

Important part being "version": "2.0.8.0", 重要部分是“版本”：“ 2.0.8.0”，

and my about page is structured like so: 我的关于页面的结构如下：

about.html about.html

<!DOCTYPE html>
  <head>
    <title>about</title>
    <link rel="stylesheet" type="text/css" href="/css/about.css">
  </head>
  <body>
    <h1 class="main-header">book writer v 2.0.8.0</h1>
    <h2 class="sub-header">This game was made by: Dragonloverlord</h2>
    <h2 class="sub-header">LICENSE</h2>
    <div class="license-div">

      </code>
    </div>
  </body>
</html>

If I can not update it directly from the manifest file then is there a angularjs csp compliant method to update the number off of a single variable so all that I have to do is link a script to any page in the app that needs the version number updated? 如果我不能直接从清单文件更新它，那么有一个与angularjs csp兼容的方法来更新单个变量的编号，所以我要做的就是将脚本链接到应用程序中需要版本号的任何页面更新？

You can update directly from the manifest: This is what the chrome.runtime.getManifest API is for. 您可以直接从清单中进行更新：这是chrome.runtime.getManifest API的用途。

In pure JavaScript, you would do something like this: 在纯JavaScript中，您将执行以下操作：

document.addEventListener('DOMContentLoaded', function () {
  manifest = chrome.runtime.getManifest();
  document.querySelector('h1.main-header').innerHTML = "book writer v " + manifest.version;
});
