我试图将这些图像放在本网站内容的隐藏/显示切换中，作为使用教程网站的人的示例。但是，每次我将图片输入“隐藏/显示”块的主体时，它都不会隐藏，它始终可见，并且隐藏/显示按钮不会执行任何操作。有关如何解决此问题的任何建议？
$(document).ready(function() {
$("button").click(function() {
$("p").toggle();
});

<h1>HHHS Homeroom GPA Calculation: Step 1</h1>
<h2>Document Your Grades</h2>
<p>For this step, you will need your paper and writing utensil. Go to HomeAccess through the CPS portal and write down your 7 classes (not including homeroom) with the percentage of your current grade. See example below. </p>
<body>
<button>Examples of Step 1 Here.</button>
<p>Write down all classes. <img src="example1.png" alt="Write Down all of your current classes on paper" height="400" width="300" class="center"></p>
<p>Document percentage points for each. <img src="example1.png" alt="Write Down all of your current classes on paper" height="400" width="300" class="center"></p>

</html>请注意，如果您的jQuery选择器设置为现在使用$("p").toggle();，您将隐藏文档中的所有p标签，这可能不是您想要的。
最好设置一个像$(".hide").toggle();这样的选择器，然后用你想要隐藏的所有内容包围该类的div，如下所示：
<div class="hide">
<p>Write down all classes. <img src="example1.png" alt="Write Down all of your current classes on paper" height="400" width="300" class="center"></p>
<p>Document percentage points for each. <img src="example1.png" alt="Write Down all of your current classes on paper" height="400" width="300" class="center"></p>
</div>
您的jquery链接无法正常工作并提供错误：请尝试以下链接和模式：
<head>
<link rel="stylesheet" href="hayes_java_project.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="gpa_calculation.js"></script>
</head>
Jquery代码工作正常。
和html内容一样（首先隐藏单个p来切换）：
<p>Write down all classes. <img src="example1.png" alt="Write Down all of your current classes on paper" height="400" width="300" class="center"></p>
<p style="display:none;">Document percentage points for each. <img src="example1.png" alt="Write Down all of your current classes on paper" height="400" width="300" class="center"></p>
希望能帮助到你。
