首先僞造一個data.json
{
"age": 20,
"code": 0,
"url": "www.123",
"likes": {
"name": "java",
"age": 2
}
}
然後通過鉤子函數進行axios網絡通信，綁定data.json，並且將該數據響應給Vue對象裏的data

<body>
<div id="vue">
{{info.age}} <br>
<a v-bind:href="info.url">點擊</a> <br>
{{info.likes.name}}
</div>
<script>
var vm = new Vue({
el: "#vue",
data() {
return {
info: { // 這裏的屬性值，要和json數據保持一致
age: null,
url: null,
likes: {
name: null,
age: null
}
}
}
},
mounted(){ // 鉤子函數鏈式編程
axios.get('data.json').then(response=>(this.info=response.data));
}
});
</script>
</body>
</html>
