Jsp学习(一)_button_框架布局&点击事件
我的运行环境在前面博客提到过，这里是在wc1项目下实践
一、基于JavaScript框架布局
栅格布局
- 新建
test.jsp
运行：
粘贴代码：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>使用一下栅格布局</title>
</head>
<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/ie10-viewport-bug-workaround.css" rel="stylesheet">
<link href="css/dashboard.css" rel="stylesheet">
<script src="js/ie-emulation-modes-warning.js"></script>
<body >
<div class="container">
<div class="row">
<div class="col-md-6">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
<div class="col-md-6">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
</div>
<div class="row">
<div class="col-md-3">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
<div class="col-md-6">
------------------------------------
</div>
<div class="col-md-3">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
</div>
</div>
<!-- Placed at the end of the document so the pages load faster -->
<script src="js/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="../../assets/js/vendor/jquery.min.js"><\/script>')</script>
<script src="js/bootstrap.min.js"></script>
<!-- Just to make our placeholder images work. Don't actually copy the next line! -->
<script src="js/holder.min.js"></script>
<!-- IE10 viewport hack for Surface/desktop Windows 8 bug -->
<script src="js/ie10-viewport-bug-workaround.js"></script>
</body>
</html>
二、button设置id 样式
1、插入界面加载函数：
$(function(){
})
2、把下面代码段中后面<script src="js/jquery.min.js"></script>这句话移到图中位置：
它的作用是：声明“$”符号
(因为页面布局是从上往下读代码，后面虽然声明了配置，但前面超前引用时显示为空)
3、设置button上的字体内容：
关键语句：
<script src="js/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$("#button1").text("name")
})
</script>
...略...
<button id="button1" type="button" class="btn btn-primary">功能一</button>
4、设置button名称：
5、列表排列
关键代码：
<ul class="nav nav-sildebar">
<li><button type="button" class="btn btn-primary">原始按钮</button></li>
<li><button type="button" class="btn btn-primary">原始按钮</button></li>
</ul>
三、button点击事件
1、点击button1、2改变 div1的内容：
关键代码：
$(function(){
$("#button1").click(function(){
$("#div1") .text("1111")
})
$("#button2").click(function(){
$("#div1") .text("2222")
})
})
.......略.......
<div class="row">
<div class="col-md-6 col-sm-3">
<!-- 功能列表 -->
<button id="button1" type="button" class="btn btn-primary">功能一</button>
<button id="button2" type="button" class="btn btn-primary">功能二</button>
</div>
<div class="col-md-6 col-sm-3" id="div1">
</div>
</div>
2、引用一个新的页面
首先新建一个b1.jsp，在<body 中输入b1。
；回到test.jsp,编辑如下：
<iframe id="myFrameId" name="myFrameName" scrolling="no" frameborder="0" width="800" height="800" src="b1.jsp"></iframe>
Day2实验全部源码：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>使用一下栅格布局</title>
</head>
<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/ie10-viewport-bug-workaround.css" rel="stylesheet">
<link href="css/dashboard.css" rel="stylesheet">
<script src="js/ie-emulation-modes-warning.js"></script>
<!-- 移动过来 -->
<script src="js/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$("#button1").click(function(){
$("#div1") .text("1111")
})
$("#button2").click(function(){
$("#div1") .text("2222")
})
})
</script>
<body >
<div class="container">
<!-- 下午内容 -->
<div class="row">
<div class="col-md-6 col-sm-3">
<!-- 功能列表 -->
<button id="button1" type="button" class="btn btn-primary">功能一</button>
<button id="button2" type="button" class="btn btn-primary">功能二</button>
</div>
<div class="col-md-6 col-sm-3" id="div1">
<iframe id="myFrameId" name="myFrameName" scrolling="no" frameborder="0" width="800" height="800" src="b1.jsp"></iframe>
</div>
</div>
<!-- 上午内容 >
<div class="row">
<div class="col-md-6">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
<div class="col-md-6">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
</div>
<div class="row">
<div class="col-md-3">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
<div class="col-md-6">
------------------------------------
</div>
<div class="col-md-3">
<button type="button" class="btn btn-primary">原始按钮</button>
</div>
</div-->
</div>
<!-- Placed at the end of the document so the pages load faster -->
<script>window.jQuery || document.write('<script src="../../assets/js/vendor/jquery.min.js"><\/script>')</script>
<script src="js/bootstrap.min.js"></script>
<!-- Just to make our placeholder images work. Don't actually copy the next line! -->
<script src="js/holder.min.js"></script>
<!-- IE10 viewport hack for Surface/desktop Windows 8 bug -->
<script src="js/ie10-viewport-bug-workaround.js"></script>
</body>
</html>
附上我们老师讲解时的样式文件：（其中404的是你未新建的页面）
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
