JavaScript How to achieve the sliding door effect?

The sliding door effect means that in the navigation bar or tab on the web page, when the mouse hovers or clicks on an option, the corresponding content area will be switched through a smooth animation effect. This effect can improve the user's interactive experience and make the web page appear more dynamic and beautiful. In this article, we'll show you how to use JavaScript to implement a sliding door effect, and provide specific code examples.

To achieve the sliding door effect, you first need some HTML and CSS structures as a basis. Let's say we have the following HTML structure:

<div class="container">
  <ul class="nav">
    <li><a href="#section1">Section 1</a></li>
    <li><a href="#section2">Section 2</a></li>
    <li><a href="#section3">Section 3</a></li>
  </ul>
  <div class="content">
    <div id="section1" class="section">Content 1</div>
    <div id="section2" class="section">Content 2</div>
    <div id="section3" class="section">Content 3</div>
  </div>
</div>

We then need to style the CSS to create a proper navigation bar and content area. An example is as follows:

.container {
  width: 600px;
  margin: 0 auto;
}

.nav {
  list-style: none;
  padding: 0;
  margin: 0;
  display: flex;
}

.nav li {
  flex: 1;
  text-align: center;
  cursor: pointer;
  background-color: #eee;
  padding: 10px;
}

.content {
  background-color: #ddd;
  padding: 20px;
  height: 200px;
}

.section {
  display: none;
}

Next, we use JavaScript to implement the sliding door effect. The following is the key JavaScript code:

document.addEventListener('DOMContentLoaded', function() {
  // 获取导航栏列表和内容区域列表
  var navItems = document.querySelectorAll('.nav li');
  var sections = document.querySelectorAll('.section');

  // 初始化第一个选项为默认选中状态
  navItems[0].classList.add('active');
  sections[0].style.display = 'block';

  // 给导航栏列表项添加事件监听器
  navItems.forEach(function(item, index) {
    item.addEventListener('click', function() {
      // 清除所有选项的选中状态
      navItems.forEach(function(navItem) {
        navItem.classList.remove('active');
      });
      // 显示点击的选项对应的内容区域
      sections.forEach(function(section) {
        section.style.display = 'none';
      });
      sections[index].style.display = 'block';
      // 给点击的选项添加选中状态
      item.classList.add('active');
    });
  });
});

In the above code, we first obtain the navigation bar list items and content area list through the querySelectorAll method. Then, we initialize the first option to the default selected state and add a click event listener to each navigation bar list item. When the user clicks on the navigation bar list item, we first clear the selected status of all options, then display the content area corresponding to the clicked option, and add the selected status to the clicked option.

Finally, we use the following code to connect the JavaScript code and the HTML file:

<script src="script.js"></script>

With the above code, we can use JavaScript to achieve a simple sliding door effect. When users hover or click on different options in the navigation bar, the content areas of the web page switch smoothly. This effect improves the user experience and makes web pages appear more dynamic and interactive.

The above is a detailed introduction on how to implement the sliding door effect in JavaScript. I hope the code examples and explanations in this article are helpful.
