本文实例为大家分享了js实现点击选项置顶动画的具体代码,供大家参考,具体内容如下
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>js置顶动画</title> <style> *{margin:0;padding:0;} ul {width: 1000px;margin:100px auto;position:relative;} li {position:absolute;height: 100px;width:900px;font-size:30px;background:#fff;line-height:100px;border:1px solid #eee;list-style:none;padding-left:50px;margin-top:-1px;transition:all .8s ease;} li button {float:right;position:relative;top:40px;right:30px;} </style> </head> <body> <ul> <li data-index="0"> <span>内容0</span> <button>置顶</button> </li> <li data-index="1"> <span>内容1</span> <button>置顶</button> </li> <li data-index="2"> <span>内容2</span> <button>置顶</button> </li> <li data-index="3"> <span>内容3</span> <button>置顶</button> </li> <li data-index="4"> <span>内容4</span> <button>置顶</button> </li> </ul> </body> <script> function $$(str) {return document.querySelectorAll(str);} // 初始化排序 function intData () { for (let i = 0, len = $$('ul li').length; i < len; i++) { $$('ul li')[i].style.top = (i * 101) + 'px'; $$('ul li')[i].style.zIndex = (i * 101); } } function bindEvent () { for (let i = 0, len = $$('ul li').length; i < len; i++) { $$('ul li')[i].onclick = function() { // 将点击的节点追加到第一个 let first = this.parentNode.firstChild; this.parentNode.insertBefore(this, first); setTimeout(() => { intData(); }, 50); }; } } intData(); bindEvent(); </script> </html>
