JS实现盒子拖拽效果
本文实例为大家分享了JS实现盒子拖拽效果的具体代码,供大家参考,具体内容如下
效果:
html代码:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>拖拽</title> <body> <div class="leftBox"></div> <div class="rightBox"> <!-- 开启拖拽属性draggable --> <div class="circle" draggable="true"></div> </div> </body> </html>
css代码:
<style> .leftBox { display: inline-block; width: 100px; height: 100px; border: 1px solid black; border-radius: 10px; position: relative; } .rightBox { display: inline-block; width: 100px; height: 100px; border: 1px solid black; border-radius: 10px; position: relative; } .circle { width: 50px; height: 50px; border-radius: 50%; background: radial-gradient(25px at center, white, skyblue); /* 绝对居中 */ position: absolute; left: 50%; margin-left: -25px; top: 50%; margin-top: -25px; } </style>
js代码:
<script> //获取dom元素,分别是左盒子 圆圈 右盒子 var leftBox = document.querySelector('.leftBox'); var circle = document.querySelector('.circle'); var rightBox = document.querySelector('.rightBox'); var text = document.querySelector('.text'); //移动circle circle. //开启左盒子的移入事件 leftBox.ondragover = function (event) { event.preventDefault(); } leftBox.ondrop = function () { leftBox.appendChild(circle); } //开启右盒子的移入事件 rightBox.ondragover = function (event) { event.preventDefault(); } rightBox.ondrop = function () { rightBox.appendChild(circle); } </script>
关于事件的用法,官方用到了object.addEventListener("dragover", myScript)和event.target.id
