จะสลับแถวของตาราง จะทำยังไง

วิธีการ

//สลับด้วย index ของ แถว

function exchange(i, j, tableID)
{
	var table = document.getElementByID('tableID');
	var trs = oTable.tBodies[0].getElementsByTagName("tr");

	if(i == j+1) {
		oTable.tBodies[0].insertBefore(trs[i], trs[j]);
	} else if(j == i+1) {
		oTable.tBodies[0].insertBefore(trs[j], trs[i]);
	} else {
		var tmpNode = oTable.tBodies[0].replaceChild(trs[i], trs[j]);
		if(typeof(trs[i]) != "undefined") {
			oTable.tBodies[0].insertBefore(tmpNode, trs[i]);
		} else {
			oTable.appendChild(tmpNode);
		}
	}
}

//สลับด้วย Object ของ Row (tr)
function exchange(oRowI, oRowJ, oTable)
{
	if(oRowI.rowIndex == oRowJ.rowIndex+1) {
		oTable.insertBefore(oRowI, oRowJ);
	} else if(oRowJ.rowIndex == oRowI.rowIndex+1) {
		oTable.insertBefore(oRowJ, oRowI);
	} else {
		var tmpNode = oTable.replaceChild(oRowI, oRowJ);
		if(typeof(oRowI) != "undefined") {
			oTable.insertBefore(tmpNode, oRowI);
		} else {
			oTable.appendChild(tmpNode);
		}
	}
}
