Hi I am trying to try out some jQuery and having no luck at all. Was writing code and what not and nothing was working. So I tried some JQuery from w3schools and that didn't even work.Any idea why I cant get it to work?

将其复制到记事本中，保存下来，然后在chrome中运行，当我按下按钮时什么也没发生.
Copied that into notepad, saved it then ran it in chrome, when I pressed the button nothing happened.

推荐答案
这里的问题是用于加载jQuery的方案相对URL.由于我假设您正在本地加载html文件，因此页面的方案为file://.当您使用//作为源来加载jQuery时，它将在本地文件系统上查找名为ajax.googleapis.com的文件夹.用https://替换脚本标记中的//来解决您的问题.
The problem here is the scheme relative url that you are using to load jQuery. Since I assume you are loading the html file locally, your page's scheme is file://. When you go to load jQuery using // as the source it is looking on your local filesystem for a folder called ajax.googleapis.com. Replace // in your script tag with https:// to solve your problem.
