使用jquery与bootstrap实现了一个比较简单但功能齐全的增删改查功能的后台管理页面，虽然只是一个CRUD页面，但麻雀虽小五脏俱全，JS常用的功能都用到了，本例用原生的jquery与bootstrap配合使用，不考虑JS的重构性及打包，该例子零耦合，开箱即用。
先看Demo：
一、用到的Jquery功能
1、获取/赋值input输入值
$("#my_id").val();// 获取$("#my_id").val(“user_id");// 赋值2、获取/赋值textarea文本域输入值
$("#my_textarea").val();// 获取$("#my_textarea").val("my_textarea");// 赋值// 文本域显示默认值，这个和input不一样，不能通过value赋默认值<textarea name="my_textarea" readonly="true"style="width:100px;height:30px;">这里是文本域默认的内容</textarea>3、隐藏/显示输入框
$("#my_input").hide();$("#my_input").show();4、获取表单form输入的数据
$("#my_input").hide();$("#my_input").show();二、示例代码
示例前端active_list.html代码：
