基本结构：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/vue.js"></script>
</head>
<body>
<div id="container">
{{code}}
从vm中获取的数据为：{{str}}
</div>
<script type="text/javascript">
var vm = new Vue({
el:"#container",
data:{
code:101,
str:"cqyzs"
}
});
</script>
</body>
</html>
1.基本类型数据和字符串
{{code}}
{{str}}
-------------------------------------------
data:{
code:101,
str:"test"
}
2.对象类型数据
(支持ognl语法)
{{stu.stuNum}}
--------------------------
stu:{
stuNum:"10001",
stuName:"张三",
tudGender:"M",
stuAge:20
}
3.条件：v-if
<label v-if="stu.stuGender=='M' ">男</label> <br />
------------------------------------------------------------------
stu:{
stuNum:"10001",
stuName:"张三",
stuGender:"M",
stuAge:20
}
4.循环：v-for
<table border="1" cellspacing="0" width="400">
<tr>
<th>序号</th>
<th>学号</th>
<th>姓名</th>
<th>性别</th>
<th>年龄</th>
</tr>
<tr v-for="s,index in stus">
<td>{{index+1}}</td>
<td>{{s.stuNum}}</td>
<td>{{s.stuName}}</td>
<td>
<label v-if="s.stuGender == 'M'">男</label>
<label v-if="s.stuGender == 'F'">女</label>
</td>
<td>{{s.stuAge}}</td>
</tr>
</table>
------------------------------------------------------------------------------------------
stus:[
{
stuNum:"10001",
stuName:"张三",
stuGender:"M",
stuAge:20
},
{
stuNum:"10002",
stuName:"李四",
stuGender:"F",
stuAge:21
},
{
stuNum:"10003",
stuName:"王五",
stuGender:"M",
stuAge:22
}
]
5.v-bind：绑定标签属性
<input type="text" value="str" />
<input type="text" v-bind:value="str" />
<table border="1" cellspacing="0" width="400">
<tr>
<th>序号</th>
<th>学号</th>
<th>头像</th>
<th>姓名</th>
<th>性别</th>
<th>年龄</th>
</tr>
<tr v-for="s,index in stus">
<td>{{index+1}}</td>
<td>{{s.stuNum}}</td>
<td>
<img height="60" v-bind:src="s.stuImg" />
</td>
<td>{{s.stuName}}</td>
<td>
<label v-if="s.stuGender == 'M'">男</label>
<label v-if="s.stuGender == 'F'">女</label>
</td>
<td>{{s.stuAge}}</td>
</tr>
</table>
---------------------------------------------------------------------------------
stus:[
{
stuNum:"10001",
stuName:"张三",
stuGender:"M",
stuAge:20,
stuImg:"img/2.jpg"
},
{
stuNum:"10002",
stuName:"李四",
stuGender:"F",
stuAge:21,
stuImg:"img/3.jpg"
},
{
stuNum:"10003",
stuName:"王五",
stuGender:"M",
stuAge:22,
stuImg:"img/4.jpg"
}
]
v-bind: 可以省略为： ：
<table border="1" cellspacing="0" width="400">
<tr>
<th>序号</th>
<th>学号</th>
<th>头像</th>
<th>姓名</th>
<th>性别</th>
<th>年龄</th>
</tr>
<tr v-for="s,index in stus">
<td>{{index+1}}</td>
<td>{{s.stuNum}}</td>
<td>
<img height="60" :src="s.stuImg" />
</td>
<td>{{s.stuName}}</td>
<td>
<label v-if="s.stuGender == 'M'">男</label>
<label v-if="s.stuGender == 'F'">女</label>
</td>
<td>{{s.stuAge}}</td>
</tr>
</table>
6.表单标签的双向绑定：v-model
(使用在表单输入标签中，只针对value使用(v-model:value)，可以简写为v-model。)
<input type="text" v-model:value="str" />
<input type="text" v-model="str" /> <!--简写-->
---------------------------------------------------------------
data{
stu:{
stuImg:"img/1.jpeg"
}
