表格删除 | 易学教程

布局：

div.wrap > input *2 + table

table > thead + tbody

thead > tr > th*3

tbody > tr (x4) > td (x3) > a.get

案例分析：

1，点击清空按钮，tbody全部清空，只剩下标题栏

2，点击最后一列删除的a链接，所在的一行都会删除 $(this).parent().parent()

3，点击添加按钮，会添加一行内容 $("<tr>......</tr>").appendTo("tbody") ；

4 ，注意新添加的一行也要绑定事件，点击删除可以删除当前行，所以需要事件委托

jQuery代码

$("#btnEmpty").on("click" , function(){
   $("tbody").empty();
})
$("tbody").on("click"  , ".delete“ , function(){
   $(this).parent().parent().remove();
})
$("#btnAdd").on("click" , function(){
   $("<tr>
      <td>jQuery</td>
      <td>传智播客-前端与移动开发学院</td>
      <td><a href="javascript:;" class="delete">DELETE</a></td> 
      </tr>")
      .appendTo("tbody");
})
