我的 Chrome 扩展程序是灰色的，并且不会显示弹出窗口。我试图让它在“https://scratch.mit.edu ”和所有子域上工作，但它在每个站点上都是灰色的。该弹出窗口也不会显示在任何网站上。
manifest.json:
{
"manifest_version": 2,
"background": {
"page": "background.html"
},
"page_action": {
"default_icon": {
"19": "images/icon19.png",
"38": "images/icon38.png"
},
"default_title": "Scratch theme loader",
"default_popup": "popup.html"
},
"permissions": [
"storage",
"declarativeContent",
"https://scratch.mit.edu/*",
"https://pastebin.com/raw/*"
]
}
背景.html:
<!DOCTYPE html>

<head>
<title>Background operation for Scratch Themes</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {

chrome.pageAction.show(tabId);

chrome.pageAction.hide(tabId);

最佳答案
您必须将所有 javascript 代码放在 js 文件中，后台、弹出窗口和其他扩展页面中不允许使用 html 脚本，甚至 onclick 属性也不允许。
