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 {
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 }; }
