on的簡單事件
//1. 找到清空按鈕，註冊點擊事件，清空tbody $("#btn").on("click", function () { $("#j_tb").empty(); });
on的委托事件
//2. 找到delete，註冊點擊事件 $("#j_tb").on("click", ".get", function () { $(this).parent().parent().remove(); });
on的簡單事件
//3. 找到添加按鈕,註冊點擊事件 $("#btnAdd").on("click", function () { $('<tr> <td>jQuery111</td> <td>傳智播客-前端與移動開發學院111</td> <td><a href="javascrip:;" class="get">DELETE</a></td> </tr>').appendTo("#j_tb"); });
效果如下：
