html" title=前端>前端开发 – 自定义鼠标指针样式
一：效果展示
由于我使用的图片是
JPEG格式，所以显得很突兀。大家使用使用矢量图形SVG格式就会显得很正常
二：源码分享

</style>
3.JavaScript代码解析
<script>document.addEventListener('DOMContentLoaded', () => {// 创建一个div元素作为自定义光标const cursor = document.createElement('div');cursor.classList.add('custom-cursor', 'cursor-style-1'); // 默认光标样式document.body.appendChild(cursor);// 监听鼠标移动事件，更新自定义光标的位置document.addEventListener('mousemove', (e) => {cursor.style.left = `${e.clientX}px`;cursor.style.top = `${e.clientY}px`;});// 获取所有样式按钮const buttons = document.querySelectorAll('.style-button');// 定义全局函数，用于切换光标样式window.setCursorStyle = function(style) {// 移除自定义光标上的所有样式类cursor.classList.remove('cursor-style-1', 'cursor-style-2', 'cursor-style-3', 'cursor-style-4', 'cursor-style-5', 'cursor-style-6');cursor.classList.add(style); // 添加新的样式类// 移除所有按钮的active类buttons.forEach(button => button.classList.remove('active'));// 给当前点击的按钮添加active类document.querySelector(`.style-button[onclick*="${style}"]`).classList.add('active');};});
