用js来实现div元素的拖拽。
HTML代码如下。
<!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>Document</title> <style> *{margin:0;padding: 0} #box{ width: 100px; height: 100px; background: red; position: absolute; } </style> </head> <body> <div id="box"></div> </body> </html>
script代码。
<script>
var oBox = document.getElementById("box");
oBox.onmousedown = function (e) {
var e = e||event;
var disX = e.offsetX;
var disY = e.offsetY;
document.onmousemove = function(e){
var e = e||event;
var x = e.clientX - disX;
var y = e.clientY - disY;
oBox.style.left = x + "px";
oBox.style.top = y + "px";
}
document.onmouseup = function(){
document.onmousemove = null;
document.onmouseup = null;
}
}
</script>
