代码说明:
html部分:
<html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8"/> <meta http-equiv="X-UA-Compatible" content="IE=edge"/> <title>拖拽文字选中</title> <script type="text/javascript" src="/image/move_img.js"></script> <style> #div1 { width: 100px; height: 100px; /*background: red;*/ position: absolute; } </style> </head> <body> <div id="div1">jghjhukj1111<br/>huhujhjgj111</div> </body> </html>
js拖动部分:
window.onload = function () { var oDiv = document.getElementById('div1'); var disX = 0; var disY = 0; oDiv.onmousedown = function (ev) { var oEvent = ev || event; disX = oEvent.clientX - oDiv.offsetLeft; disY = oEvent.clientY - oDiv.offsetTop; if (oDiv.setCapture) { //IE oDiv.onmousemove = mouseMove; oDiv.onmouseup = mouseUp; oDiv.setCapture();//IE } else { //chrome,ff document.onmousemove = mouseMove; document.onmouseup = mouseUp; } function mouseMove(ev) { var oEvent = ev || event; var left = oEvent.clientX - disX; var top = oEvent.clientY - disY; oDiv.style.left = left + 'px'; oDiv.style.top = top + 'px'; } function mouseUp() { this.onmousemove = null; this.onmouseup = null; if (oDiv.releaseCapture) { oDiv.releaseCapture();//IE } } return false;//chrome,ff,IE9 }; }
