How to use Layui to implement foldable product classification filtering function

How to use Layui to implement foldable product classification filtering function requires specific code examples

Introduction:
With the continuous development of the e-commerce industry, product classification Filtering has become an important part of a website. Layui is a very popular front-end framework. It provides rich components and simple APIs, which can help us quickly implement various functions. This article will introduce how to use Layui to implement the foldable product classification filtering function, and provide detailed code examples.

1. Layout structure

First, we need to determine the layout structure of the product classification filtering function. Generally speaking, this feature usually includes a product category list and a collapse/expand button. When the user clicks the collapse/expand button, the product category list will be displayed or hidden in a collapsed/expanded form.

The following is an example of our layout structure:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>商品分类筛选</title>
    <link rel="stylesheet" href="layui/css/layui.css">
</head>
<body>
    <div class="layui-form-item">
        <div class="layui-input-block">
            <button class="layui-btn" id="toggle-btn">折叠/展开</button>
            <ul class="category-list">
                <li>分类1</li>
                <li>分类2</li>
                <li>分类3</li>
            </ul>
        </div>
    </div>
    <script src="layui/layui.js"></script>
    <script>
        layui.use('form', function(){
            var form = layui.form;
        });
    </script>
</body>
</html>

2. Implement the folding/expanding function

Next, we need to use Layui’s event handling function and CSS class to implement it Fold/expand functionality. The specific steps are as follows:

Bind the click event on the button element.

<button class="layui-btn" id="toggle-btn">折叠/展开</button>

Copy after login

Use CSS to add hidden and visible classes to the product classification list.

<ul class="category-list layui-hide">...</ul>

Copy after login

In the handler function of the click event, use Layui's event handler function and CSS class to switch the hidden and displayed states.

layui.use('form', function(){
    var form = layui.form;
    form.on('button(toggle)', function(data){
        var categoryList = document.querySelector('.category-list');
        layui.$(categoryList).toggleClass('layui-hide');
    });
});

                分类1
                分类2
                分类3
            
        
    
    
    <script>
        layui.use('form', function(){
            var form = layui.form;
            form.on('button(toggle)', function(data){
                var categoryList = document.querySelector('.category-list');
                layui.$(categoryList).toggleClass('layui-hide');
            });
        });
