添加/删除 一条空的数据

1. 拼接字符串

$("这里是点击按钮的类名").click(function(){
    var str='<tr>'+'<td style="width:16%;min-width: 112px"></td>'+'<td style="width:19%;min-width: 133px"></td>'+
        '<td style="width:19%;min-width: 133px"></td>'+'<td style="width:10%;min-width: 70px"></td>'+'<td style="width:10%;min-width: 70px"></td>'+
        '<td style="width:16%;min-width: 112px"> <div class="automatic-input2"><input type="text"/></div> </td>'+
        '<td style="width:10%;min-width: 70px"> <div><a href="###" class="delRow">删除</a></div>'
        +'</tr>';
    $(".Stock-automatic2-content table tbody").append(str);
    $(".Popup-content-Addshop").hide();
    $(".layer").hide();
});

 2. 添加按钮后，删除一行数据

$(".Stock-automatic2-content").delegate(".delRow","click",function(event){
    var $this = $(this);
    var target = event.target;
    var trNode = $(target).parentsUntil("tr")[1];
    $(trNode.parentNode).remove();
});
