Javascript JQuery和Chrome扩展
我正在尝试开发一个测试chrome扩展,以了解JQuery如何与chrome扩展一起工作。根据提供的代码,我认为应该将弹出窗口的背景更改为黄色 我尝试过使用内容脚本和后台加载jquery.js。当我通过backgroundscripts命令加载它时,它显示jquery.js已加载 这是我的档案: manifest.jsonJavascript JQuery和Chrome扩展,javascript,jquery,html,google-chrome,google-chrome-extension,Javascript,Jquery,Html,Google Chrome,Google Chrome Extension,我正在尝试开发一个测试chrome扩展,以了解JQuery如何与chrome扩展一起工作。根据提供的代码,我认为应该将弹出窗口的背景更改为黄色 我尝试过使用内容脚本和后台加载jquery.js。当我通过backgroundscripts命令加载它时,它显示jquery.js已加载 这是我的档案: manifest.json { "name": "Hello World!", "version": "1.0", "manifest_version": 2, "descrip

我的扩展文件夹中也有jquery.js。如果有人能给我一些别的东西来让它工作,或者能给我展示一个链接jquery的chrome扩展的非常好的工作示例,那就太好了 你一直没有把不该放在一起的东西混在一起 有一件事你做错了:
由于您不希望在单击浏览器操作按钮时出现弹出窗口,因此不应指定“默认弹出窗口”: manifest.json:

如果您还有其他问题,请随时回来:)
为了完整性…
…让我只提一下,还有其他可能的方法,如:
没错,有什么问题吗?它应该会起作用。看看这个网站:当我加载插件并点击它时,它只显示一个小的弹出框,右下角和右下角有一个灰色的小框。我尝试了这个链接,但我仍然无法让它工作。我更新了manifest_版本2,在文件夹中获得了jQuery 1.10.2分钟,当我点击插件时,什么都没有发生。我还将background_页面更新为“background”:{“page”:“background.html”}您把事情弄混了一点。你想达到什么目的?使“*”上每个
元素的背景自动变为黄色?或者有一个按钮,当点击该按钮时,活动选项卡页面的每个元素的背景都会变成黄色?@user2200175敲打,敲打!您是否尝试过我下面建议的解决方案?你让它起作用了吗?
