获取html绝对坐标

function findPosition(oElement) {
	var x2 = 0;
	var y2 = 0;
	var width = oElement.offsetWidth;
	var height = oElement.offsetHeight;
	//alert(width + "=" + height);
	if (typeof (oElement.offsetParent) != 'undefined') {
		var posY = 0
		for ( var posX = 0; oElement; oElement = oElement.offsetParent) {
			posX = posX + oElement.offsetLeft;
			posY = posY + oElement.offsetTop;
		}
		x2 = posX + width;
		y2 = posY + height;
		return [ posX, posY, x2, y2 ];
	} else {
		x2 = oElement.x + width;
		y2 = oElement.y + height;
		return [ oElement.x, oElement.y, x2, y2 ];
	}
}
