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">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:
