将 jQuery 加载到 chrome-extension [英] Loading jQuery into chrome-extension
问题描述
我正在尝试进入 Chrome 扩展程序的神奇世界.现在我已经建立了我的清单，试图加载 jquery.
I'm trying my first step into the magical world of Chrome Extensions. Now i've build up my manifest trying to load jquery.
{
"name": "Test Extension",
"version": "0.1",
"manifest_version": 2,
"description": "First try",
"options_page": "options.html",
"content_scripts": [{
"matches": ["chrome-extension://*/*"],
"js": ["jquery.js", "popup.js"],
"run_at": "document_end"
}],
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html",
"default_title": "Click me!"
}
}
实际上尝试重新加载扩展告诉我匹配项"与有效架构不匹配.
Actually trying to reload the extension tell me that the "matches" do not match a valid schema.
但这还不是全部.为了克服它，我尝试将匹配"值更改为 *://*/* 并重新加载.嗯，扩展似乎正确加载，但似乎 jquery 没有加载，因为我可以从 popup.js 得到的错误只是告诉我
But that's not all. To get over it, i've tried just changing the "matches" value to *://*/* and reload.
Well, the extension seems to load correctly but seems like the jquery is not loaded due to the error i can get from the popup.js that just tell me
未捕获的引用错误:$ 未定义
Uncaught ReferenceError: $ is not defined
实际上 HTML 只是:
Actually the HTML is just:
<!doctype html>
<html>
<head>
<title>Test Extension</title>
<link rel="stylesheet" style="text/css" src="style.css">
</head>
<body>
<div id="test"></div>
</body>
</html>
<script type="text/javascript" src="popup.js"></script>
popup.js 代码就是这样做的:
The popup.js code just do this:
$("#test").html("Foo!");
推荐答案
内容脚本将永远在扩展的上下文中运行.在浏览器操作弹出窗口中加载脚本的正确方法是将其包含在您的代码中.让您的清单文件:
Content scripts will never run in the context of an extension. The correct way to load scripts in your browser action popup is by including it in your code. Let your manifest file be:
{
"name": "Test Extension",
"version": "0.1",
"manifest_version": 2,
"options_page": "options.html",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html",
"default_title": "Click me!"
}
}
和popup.html:
...
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="popup.js"></script>
