//2.创建组件

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>

data:function(){
return{

var self=this;
axios({
method:"get",//get post 获取方法
url:'fruit.json' //路径
}).then(function(resp){//请求成功
console.log(resp.data)

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.引入ajax：
1.>下载axios.js
import axios from 'axios'
export default{
data:function(){
return{txt:null} //不确定数据类型，所以将txt的值设为空值；
},
methods:{},
mounted:function(){
var self=this;
axios({
method:'get' //请求方法
url：'../../static/ .json'
}).then(function(aaa){
console.log(aaa.data)
self.txt=aaa.data //单独的aaa.data无法加载，需将数据赋值给txt到页面
}).catch(function(bbb){
console.log(bbb)
})
}
}
