//2.创建组件
var Home={
template:`
<h1>这是首页</h1>
`
}
var User={
template:`
<div>
<h1>这是用户页</h1>
<table border=1 cellspacing=0>
<thead>
<tr>
<th>编号</th>
<th>品名</th>
<th>单价</th>
<th>数量</th>
<th>小计</th>
</tr>
</thead>
<tbody>
<tr v-for="value in list">
<td>{{value.num}}</td>
<td>{{value.pname}}</td>
<td>{{value.price}}</td>
<td>{{value.count}}</td>
<td>{{value.sub}}</td>
</tr>
</tbody>
</table>
</div>
`,
data:function(){
return{
list:null
}
},
mounted:function(){
var self=this;
axios({
method:"get",//get post
url:'fruit.json'
}).then(function(resp){//请求成功
console.log(resp.data)
self.list=resp.data;
}).catch(function(err){//请求失败
console.log(err)
})
}
}
//3.配置路由
const routes=[
{path:'/',component:Home},
{path:'/home',component:Home},
{path:'/user',component:User}
]
//4.创建路由实例
const router=new VueRouter({
routes:routes,
linkActiveClass:'active'
})
//5.路由实例挂载到vue实例上
new Vue({
el:'#app',
router:router
})
</script>
</body>
</html>
2、新建一个json后缀名的文件，然后在里面写数据
[
{
"num":1,
"pname":"apple",
"price":3,
"count":2,
"sub":6
},
{
"num":2,
"pname":"pear",
"price":4,
"count":3,
"sub":12
},
{
"num":3,
"pname":"banana",
"price":5,
"count":4,
"sub":20
}
]
