$(function() {
$("#btnAdd").click(function() {
var num = $("#hidNum").val(); //
num = parseInt(num);
num++; //點擊自加
$("#hidNum").val(num); //重新賦值
$("#tRow0").clone(true).attr("id", "tRow" + num).appendTo("#tblData"); //clone tr 并重新給定ID,裝到table
$("#tRow" + num + " td").each(function() {//循環克隆的新行里面的td
$(this).find("input[type='text']").val(""); //清空克隆行的數據
//修改相關屬性
$(this).find("input[name='txtID0']").attr("id", "txtID" + num).attr("name", "txtID" + num);
$(this).find("input[name='txtTitle0']").attr("id", "txtTitle" + num).attr("name", "txtTitle" + num);
