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
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持三水点靠木。
