How would I do this?

You can just put jquery.js into extension folder and include it in the manifest:
您可以将 jquery.js 放入扩展文件夹并将其包含在清单中：
{
"name": "My extension",
...
"content_scripts": [
{
"matches": ["http://www.google.com/*"],
"css": ["mystyles.css"],
"js": ["jquery.js", "myscript.js"]
}
],
...
}
You don't need to worry about conflicts with jQuery on a parent page as content scripts are sandboxed.
您无需担心与父页面上的 jQuery 冲突，因为内容脚本是沙盒化的。

You can do this from a script in your background_page HTML:
您可以从 background_page HTML 中的脚本执行此操作：
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.executeScript(null, { file: "jquery.min.js" }, function() {
chrome.tabs.executeScript(null, { file: "content_script.js" });
});
});
Then in content_script.js do whatever you like:
然后在 content_script.js 中做任何你喜欢的事情：
$('#header').hide();
Note that even if the page you've injected into already has jQuery loaded, you're still hitting your own instance of the jQuery object, which is accessing the page via the DOM. (document).
请注意，即使您注入的页面已经加载了 jQuery，您仍然会访问您自己的 jQuery 对象实例，它通过 DOM 访问页面。（文档）。

} ]
