如下圖所示：
複製代碼代碼如下:
//傳回數組類型
function findPosition(oElement) {//oElement 目前元素
if (typeof (oElement.offsetParent) != 'undefined') {
for (var posX = 0, posY = 0; oElement; oElement = oElement.offsetParent) {
posX += oElement.offsetLeft;
posY += oElement.offsetTop;
}
}
var array = [posX, posY];
return array;
}
//取得觸發事件的控制項在整個頁面的絕對的X座標
function findPositionX(oElement) {
if (typeof (oElement.offsetParent) != 'undefined') {
for (var posX = 0; oElement; oElement = oElement.offsetParent)
{
posX += oElement.offsetLeft;
}
}
return posX;
}
//取得觸發事件的控制項在整個頁面的絕對的Y座標
function findPositionY(oElement) {
if (typeof (oElement.offsetParent) != 'undefined') {
for (var posY = 0; oElement; oElement = oElement.offsetParent) {
posY += oElement.offsetTop;
}
}
return posY;
}
