为什么jQuery在我的家用(本地)计算机上不起作用? [英] Why jQuery does not work on my home (local) machine?
问题描述
我的问题不是关于为什么我编写的特定jQuery不能正常工作，因为它根本没有jQuery正常工作.我什至没有直接从W3 Schools等地方复制的工作示例.
My question isn't so much about why a specific bit of jQuery I've written isn't working as it is about no jQuery at all is working; not even working examples I've copied directly from places like W3 Schools.
我在软件开发工作中不时使用jQuery，尽管我绝不是专家，但我对此非常熟悉.我第一次尝试在家庭项目中使用jQuery，无论我做什么，都无法使用.我在下面提供的示例就像我能想到的一样简单，甚至无法正常工作.
I use jQuery from time to time in my software development job and while I am by no means an expert, I am pretty familiar with it. For the first time I am trying to use jQuery in a home project and no matter what I do, none of it will work. The example I've included below is about as simple as I can think of, and even it will not work.
<!DOCTYPE HTML>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
</head>
<body>
<div>
<p>Old Stuff</p>
</div>
<script type="text/javascript">
$('p').text('New Stuff');
</script>
</body>
</html>
这可能是什么问题?
推荐答案
代码正常.
该脚本未下载，因为您可能未在部署代码，因此浏览器将默认使用file://协议.
The script is not downloading because, as you probably are not deploying the code, the browser will default to the file:// protocol.
要解决此问题，请在脚本标记处添加http::
To solve it, add the http: at the script tag:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js">
</script>
