我有一个谷歌chrome打包的应用程序，我想根据其清单文件更新该应用程序的about页面上的版本号。我的清单文件是这样的：

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"
    ]
}

重要部分是"版本"："2.0.8.0"，

我的about页面的结构是这样的：

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">

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

如果我不能直接从清单文件更新它，那么是否有一个符合angularjs-csp的方法来更新单个变量的编号，这样我所要做的就是将脚本链接到应用程序中任何需要更新版本号的页面？

您可以直接从清单更新：这就是chrome.runtime.getManifest API的用途。

在纯JavaScript中，您可以执行以下操作：

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