Your script tags are wrong, should be as follows: 您的脚本标签有误，应如下所示：
<script type="text/javascript" src="jquery-min.js"></script>
<script type="text/javascript">
$(".c").click(function() {
//$("p").html("my text has changed");
alert('hi');
});
</script>
And you probably will have to add a slash to the src if you get a 404: 如果您收到404，则可能必须在src中添加一个斜杠：
<script type="text/javascript" src="/jquery-min.js"></script>
Note that you've written "type=text/javascript" and it should be type="text/javascript" 请注意，您已编写"type=text/javascript" ，并且应为type="text/javascript"

It's likely that the content in your script tag is being ignored . 您的script标记中的内容可能会被忽略 。 Include JQuery and your content script separately. 分别包含JQuery和内容脚本。
<script type="text/javascript" src="/jquery-min.js"></script>
<script type="text/javascript">
$(function() {
$(".c").click(function()
{
//$("p").html("my text has changed");
alert('hi');
});
});
</script>
Also as mentioned below, you want to wait until the document ready event to try do anything against the dom. 同样如下所述，您想等到文档准备事件尝试对dom执行任何操作。

I fixed your code as below. 我将您的代码固定如下。
<html> <head> <title>My second jQuery practice</title> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script> <style> .c{ width: 100px; height:100px; border-radius: 50px; background-color: red; } </style> <script> $(document).ready(function() { $(".c").click(function() { alert("You clicked on a div."); }); }); </script> </head> <body> <div class="c"></div> <p> My text </p> </body> </html>
