我刚开始学习chrome扩展的基础知识。使用“页面更改”扩展名(可更改整个网页的背景颜色)作为模板,我想制作一个更改所有文字背景颜色的扩展名。
来自https://developer.chrome.com/extensions/samples的页面更新: background.js:
" "
的manifest.json:
0
我可以更改以下代码行来改为选择所有文字吗?
// Copyright (c) 2011 The Chromium Authors. All rights reserved.

// Called when the user clicks on the browser action.
chrome.browserAction.onClicked.addListener(function(tab) {
// No tabs or host permissions needed!
console.log('Turning ' + tab.url + ' red!');
chrome.tabs.executeScript({
code: 'document.body.style.backgroundColor="red"'
});
});
我尝试将其更改为:
{
"name": "Page Redder",
"description": "Make the current page red",
"version": "2.0",
"permissions": [
"activeTab"
],
"background": {
"scripts": ["background.js"],
"persistent": false
},
"browser_action": {
"default_title": "Make this page red"
},
"manifest_version": 2
}
with content.css:
chrome.tabs.executeScript({
code: 'document.body.style.backgroundColor="red"'
但没有成功。
