正常应该是鼠标光标点到哪里红色的left值应该就是光标的坐标才对。。但是现在我设置了transform: scale(0.8,0.8); 红色的位置就不对了。。

实现缩放情况下的拖拽 <!doctype html> <html> <head> <title></title> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/zepto/1.1.6/zepto.min.js"></script> <meta charset="utf-8" /> <style type="text/css"> body,html{ height:100%; } *{margin: 0;padding: 0;} .wrap{ width: 500px;height:100%; position: relative;margin: 0 auto;background: blue; transform: scale(0.2,0.2)} .box{ position: absolute;top:0;left:0; background: red;width: 200px;height: 200px; } </style> </head> <body> <div class="wrap"> <div class="box"></div> </div> <script type="text/javascript"> var element = $(".box") , e = $(".wrap"); var startX = 0, startY = 0, posY = 0, posX = 0; e.on("mousedown", function(event) { startX = event.clientX - e.offset().left; startY = event.clientY - e.offset().top; element.css({ left : startX/ 0.8, top: startY/0.8 }); document.onmousemove = function(event) { startX = event.clientX - e.offset().left; startY = event.clientY - e.offset().top; element.css({ left : startX/ 0.2, top: startY/0.2 }); }; document.onmouseup = function() { document.onmousemove = null; document.onmouseup = null; }; }); </script> </body> </html>

e.on("mousedown", function(event) { startX = event.clientX - e.offset().left; startY = event.clientY - e.offset().top; element.css({ left : startX/ 0.8, top: startY/0.8 }); console.log(startX,startY); // console.log(event.clientX-(e.offset().left+100)) }); 现在你能够实现点击点为box 的左上位置
