我有一个 Google Chrome 打包应用程序，我想根据其 list 文件更新该应用程序的“关于”页面上的版本号。我的 list 文件如下所示:
list .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"version": "2.0.8.0",
我的关于页面的结构如下:
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">

如果我无法直接从 list 文件更新它，那么是否有一个符合 angularjs csp 标准的方法来更新单个变量的数量，所以我所要做的就是将脚本链接到应用程序中需要的任何页面版本号更新了吗？
最佳答案
您可以直接从 list 更新:这就是chrome.runtime.getManifest API 是为了。
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;
});
