How to use Layui to achieve picture borders and filter effects

Overview:
Layui is a simple and easy-to-use front-end UI framework that provides a wealth of components and styles, allowing developers to easily build beautiful web interfaces. In this article, we will introduce how to use Layui to implement image borders and filter effects, and provide specific code examples.

1. Realize the picture border effect

1. Introduce Layui related files in the HTML code:

   <link rel="stylesheet" href="layui/css/layui.css">
   <script src="layui/layui.js"></script>

2. Create images containing HTML element, and add a class to identify the element:

   <div class="image-container">
       <img src="/static/imghw/default1.png"  data-src="example.jpg"  class="lazy" alt="example">
   </div>

3. Use Layui's form module to define the style by adding a class to the HTML element:

   <script>
   layui.use('form', function() {
       var form = layui.form;
       form.render();
   });
   </script>

4. Write CSS styles:

   .image-container {
       border: 1px solid #ccc;
       padding: 10px;
       display: inline-block;
   }

2. Implement image filter effects

1. Introduce Layui related files into the HTML code (ibid.).

2. Create an HTML element containing an image and add class:

   <div class="image-container">
       <img class="image-filter lazy"  src="/static/imghw/default1.png"  data-src="example.jpg"  alt="example">
   </div>

3. Use Layui's form module to define a select element for selecting filter effects:

   <select name="filter" lay-filter="filter-select">
       <option value="">原图</option>
       <option value="blur">模糊</option>
       <option value="grayscale">灰度</option>
       <option value="sepia">复古</option>
   </select>

4. Listen to changes in the select element in Layui's JavaScript code, and modify the image style according to the selected filter effect:

   <script>
   layui.use('form', function() {
       var form = layui.form;
       form.on('select(filter-select)', function(data) {
           var filter = data.value;
           var image = document.querySelector('.image-filter');
           image.style.filter = filter;
       });
       form.render();
   });
   </script>
