JavaScript 拖拽实例代码
(编辑:jimmy 日期: 2025/11/1 浏览:3 次 )
一、JS 拖拽的实现实例代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>拖拽js</title>
<style type="text/css">
html, body {
overflow:hidden;
}
body, div, {
margin:0;
padding:0;
}
body {
color:#fff;
font:12px/2 Arial;
}
p {
padding:0 10px;
margin-top:10px;
}
span {
color:#ff0;
padding-left:5px;
}
#box {
position:absolute;
width:300px;
height:150px;
background:#D5CDDA;
border:2px solid #ccc;
top:150px;
left:400px;
margin:0;
}
#drag {
height:25px;
cursor:move;
background:#724a88;
border-bottom:2px solid #ccc;
padding:0 10px;
}
</style>
</head>
<body>
<div id="box">
<div id="drag">拖动区域</div>
被拖动的整个div
</div>
</body>
</html>
<script src="/UploadFiles/2021-04-02/jquery-1.10.1.min.js">https://www.jb51.net/article/93142.htm
效果图如下:
突然发现有没有效果图都一样哈哈,不说废话了,上代码:
html代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf8">
<title>js拖拽效果</title>
<style type="text/css">
#div1 {
width : 200px;
height: 200px;
position: absolute;
background: #99dd33;
cursor: move;
}
</style>
</head>
<body>
<div id="div1"></div>
</body>
<script type="text/javascript">
// js代码
</script>
</html>
js代码:
window.onload function() {
var disX = disY = 0; // 鼠标距离div的左距离和上距离
var div1 = document.getElementById("div1"); // 得到div1对象
// 鼠标按下div1时
div1.onmousedown = function(e) {
var evnt = e || event; // 得到鼠标事件
disX = evnt.clientX - div1.offsetLeft; // 鼠标横坐标 - div1的left
disY = evnt.clientY - div1.offsetTop; // 鼠标纵坐标 - div1的top
// 鼠标移动时
document.onmousemove = function(e) {
var evnt = e || event;
var x = evnt.clientX - disX;
var y = evnt.clientY - disY;
var window_width = document.documentElement.clientWidth - div1.offsetWidth;
var window_height = document.documentElement.clientHeight - div1.offsetHeight;
x = ( x < 0 ) "px";
div1.style.top = y + "px";
};
// 鼠标抬起时
document.onmouseup = function() {
document.onmousemove =null;
document.onmouup = null;
};
return false;
};
};
当然,这个虽然支持大部分浏览器,但是,我觉得div跟随鼠标的速度有点滞后,如果有好的解决办法请联系我喔,谢谢!
