表格删除案例
//1. 找到清空按钮，注册点击事件，清空tbody
$("#btn").on("click", function () {
$("#j_tb").empty();
});
//2. 找到delete，注册点击事件
$("#j_tb").on("click", ".get", function () {
$(this).parent().parent().remove();
});
//3. 找到添加按钮,注册点击事件
$("#btnAdd").on("click", function () {
$(‘<tr> <td>jQuery111</td> <td>传智播客-前端与移动开发学院111</td> <td><a href="javascrip:;" class="get">DELETE</a></td> </tr>‘).appendTo("#j_tb");
});
效果如下：
