首先,做一个登录页面。
在这里,注意
内容框里的提示信息用placeholder

<!-- 登录页面开始 -->
<div class="container">
<h2>登录</h2>
<div class="info">
<input type="text" placeholder="用户名" id="name" maxlength="25">
</div>
<div class="code">
<input type="password" placeholder="密码" maxlength="25">

<div class="yanzheng">

</body>
</html>
登陆成功之后是内容管理系统页面
二、内容管理系统
- iframe窗口标签,框架标签 主要作用:嵌套其他页面
src 嵌入的资源
width 宽
height 高
frameborder="0" 去掉边框,是页面嵌入的更融合
name 窗口名称
- jQuery removeClass() 方法
从被选元素移除一个或多个类。
**注意:**如果没有规定参数,则该方法将从被选元素中删除所有类。
语法
$(selector ).removeClass(classname ,function*(index,currentclass)*)
参数 | 描述 |
---|---|
classname | 可选。规定要移除的一个或多个类名称。如需移除若干个类,请使用空格分隔类名称。 注意: 如果该参数为空,则将移除所有类名称。 |
function*(index,currentclass)* | 可选。返回要移除的一个或多个类名称的函数。 * index - 返回集合中元素的 index 位置。 * currentclass - 返回被选元素的当前类名。 |

2.2 数据库设置
内容设置
栏目设置
查询
sql
select content.*,channelname from content,channel where content.channelid=channel.id and available=1 order by createtime desc
三、后端传数据
把文件都转到eclipse中
