我正在尝试创建一个React应用程序/ Chrome扩展程序,该扩展程序将覆盖Google Chrome浏览器中新标签页的内容。我用过create-react-app
,只是想用App.js
内容覆盖新标签的内容。文件夹结构直接从下面的初始create-react-app
开始。
build
node_modules
Public
favicon.ico
index.html
logo192.png
logo512.png
manifest.json
src
App.css
App.js
app.test.js
index.css
index.js
logo.svg
..
..
我的manifest.json
文件看起来像这样。
{
"name": "..",
"author": "..",
"version": "1.0.1",
"manifest_version": 2,
"description": "..",
"chrome_url_overrides": {
"newtab": "index.html"
}
}
这是我的index.html
外观。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
name="description"
content="Web site created using create-react-app"
/>
<link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" />
<link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
<title>React App</title>
</head>
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
<!--
This HTML file is a template.

You can add webfonts, meta tags, or analytics to this file.
The build step will place the bundled scripts into the <body> tag.

</body>
</html>
我的index.js
文件看起来像这样。
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(<App />, document.getElementById('root'));
serviceWorker.unregister();
我尝试插入以下内容,但收到空白页。
<script src="../src/index.js"></script>
如何使用App.js
覆盖新标签的内容?
