一皿渗、測(cè)試代碼
<!DOCTYPE HTML>
<html lang="zh-cn">
<head>
<meta charset="utf-8" />
<title>Javascript</title>
<style>
body{margin:0;padding:0;background:#ccc;font-size:12px;overflow:auto}
.main{width: 500px;height: 330px;position: relative;margin: 250px auto 0;background-color: #eee;}
.box{position: absolute;width: 220px;height: 180px;background-color: orange;top: 80px;left: 80px;}
</style>
</head>
<body style="height:1600px;">
<div class="main">
<div class="box" id="box"></div>
</div>
<script>
var oBox = document.getElementById('box');
window.onload = function(){
oBox.onmousedown = function(ev){
ev = ev || window.event;
console.log(ev.offsetX, ev.offsetY);
console.log(ev.clientX, ev.clientY);
console.log(ev.pageX, ev.pageY);
console.log(ev.screenX, ev.screenY);
console.log(ev.layerX, ev.layerY);
console.log(ev.x, ev.y);
}
}
</script>
</body>
</html>
二仰冠、圖解 event.offsetX乏冀，event.clientX，event.pageX洋只，event.screenX屬性
圖解一.jpg
三辆沦、圖解 event.layerX，event.layerY 屬性
二.jpg
四识虚、圖解 event.x肢扯，event.y 屬性
三.jpg
五、jquery兼容寫法
<script>
$(function(){
$("#box").mousedown(function(event){
console.log(event.offsetX, event.offsetY);
console.log(event.clientX, event.clientY);
console.log(event.pageX, event.pageY);
console.log(event.screenX, event.screenY);
/* firefox */
console.log(event.originalEvent.layerX, event.originalEvent.layerY);
});
});
</script>
