订阅昨天搞了一個日曆選擇器的小東西，竟然發現以前用的獲取標簽的座標的函數在Firefox下不能執行，比較郁悶。于是花心思整理了一個，現此代碼支持Ie,Firefox,Opera，記錄于此！
javascript獲取座標
function getAbsPoint(e) {
var x = e.offsetLeft;
var y = e.offsetTop;
while(e = e.offsetParent) {
x += e.offsetLeft;
y += e.offsetTop;
}
return {"x": x, "y": y};
}
javascript獲取座標使用方法
<html>
<head>
<meta http-equiv=content-type content="text/html; charset=UTF-8">
<title>phplamp.org</title>
<script type="text/javascript">
function getAbsPoint(e) {
var x = e.offsetLeft;
var y = e.offsetTop;
while(e = e.offsetParent){
x += e.offsetLeft;
y += e.offsetTop;
}
return {"x": x, "y": y};
}
function phplamp(e) {
var xy = getAbsPoint(e);
alert("offsetLeft=" + xy.x + "\noffsetTop=" + xy.y);
}
</script>
</head>
<body>
<input type="button" onclick="phplamp(this)" value="點擊" />
</body>
</html>
