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

 //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;
        }
