js获取触发事件元素在整个网页中的绝对坐标(示例代码)_javascript技巧

如下所示：
代码如下:
//返回数组类型
function findPosition(oElement) {//oElement 当前元素
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;
}
//获取触发事件的控件在整个页面的绝对的X坐标
function findPositionX(oElement) {
if (typeof (oElement.offsetParent) != 'undefined') {
for (var posX = 0; oElement; oElement = oElement.offsetParent)
{
posX += oElement.offsetLeft;
}
}
return posX;
}
//获取触发事件的控件在整个页面的绝对的Y坐标
function findPositionY(oElement) {
if (typeof (oElement.offsetParent) != 'undefined') {
for (var posY = 0; oElement; oElement = oElement.offsetParent) {
posY += oElement.offsetTop;
}
}
return posY;
}
