How to use Layui to achieve image scaling effect

Layui is a simple and easy-to-use front-end framework that provides a wealth of components and interfaces to facilitate developers to quickly build pages . In the process of using Layui, we often encounter the need to implement image scaling, such as in image display, image carousel and other scenarios. This article will introduce how to use Layui to achieve image scaling effects and provide specific code examples.

1. Introducing Layui

First of all, we need to introduce the relevant resource files of Layui, including css and js files. Layui's related resource files can be introduced into the html page through the following code:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/layui@2.6.9/dist/css/layui.css" integrity="sha384-IQruhwyBgQEDoyMBSpxDntNKtwx4jvLB3X1OAyr/9fEtrC854kIfwiMSx2O6R5+a" crossorigin="anonymous">
<script src="https://cdn.jsdelivr.net/npm/layui@2.6.9/dist/layui.js" integrity="sha384-SwmyJQvZx3fDqSoi3SopGMcILpZHty6UqwzvWHmpvjpu8FOMz9i+Fqp8bXLtXFpM" crossorigin="anonymous"></script>

2. Write HTML structure

In the HTML file, we need to prepare a container div, Used to hold images. You can create a container div through the following code:

<div id="demo" style="width: 600px; height: 400px;"></div>

3. Write JavaScript code

Next, we need to write JavaScript code to achieve the image scaling effect. First, you need to initialize Layui and specify the container id. Layui can be initialized through the following code:

layui.use('layer', function(){
  var layer = layui.layer;
  
  // 添加点击事件，触发图片缩放
  layer.photos({
    photos: '#demo', // 指定容器id
    anim: 5 // 缩放动画效果
  });
});

In the above code, after initializing Layui, we added a click event. When the container div is clicked, the image scaling effect will be triggered. The container id is specified through the photos method, and the zoom animation effect is set through the anim attribute.

4. Complete code example

The following is a complete code example, including the introduction of Layui, HTML structure and JavaScript code:

  
  
  



  <div id="demo" style="width: 600px; height: 400px;"></div>

  
  <script>
    layui.use('layer', function(){
      var layer = layui.layer;
      
      // 添加点击事件，触发图片缩放
      layer.photos({
        photos: '#demo', // 指定容器id
        anim: 5 // 缩放动画效果
      });
    });
  </script>

The above is using Layui Specific code examples to achieve image zoom effects. Through the above steps, we can easily achieve the image scaling effect and improve the visualization effect and user experience of the page. Hope this article helps you!
