本文主要講v-resourse 獲取json數(shù)據(jù)并傳遞到DOM中，具有一定的參考價值，感興趣的小伙伴們可以參考一下

1.demo目錄，不要管index.html和index.js

2.html頁面 vue-resourse-josn1.1.html展示json中的數(shù)據(jù)

<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>vue-resourse-json</title></head><body><div id="app"><ul><li v-for="item in itemList" :id="item.id" style="list-style-type: none;">編號：{{item.id}}</br>作者：{{item.author}}</br>書名{{item.name}}</br>價格：{{item.price}}</br>出版時間{{item.time}}</br></li></ul></div> <script src="static/js/libs/vue.js"></script><script src="static/js/libs/vue-resource.min.js"></script><script type="text/javascript" src="static/js/vue-resourse-json.js"></script></body></html>

3.js vue-resourse-json.js

var app = new Vue({el:"#app",data:{//聲明空數(shù)組，進行數(shù)據(jù)接收，最后傳遞到前端頁面itemList:[], },//向data數(shù)組里添加數(shù)據(jù)mounted:function(){this.getData();},methods: {getData:function () {var self = this;this.$http.get("static/data/list_json.json").then(function (res) {console.log(res);//var lens = res.body.lists.length;//console.log(lens);//獲取了當前數(shù)組的長度，為3for(var i= 0,len=res.body.lists.length;i<len;i++){//已經(jīng)獲取json數(shù)組中的數(shù)據(jù)，接下來如何傳遞到前端頁面中//獲取全部數(shù)據(jù)var selData = res.body.lists[i]; //console.log(selData);//獲取數(shù)組中的部分數(shù)據(jù)var part = res.body.lists[i].name;//console.log(part);//將獲取的數(shù)據(jù)push到空的數(shù)組中itenList，self.itemList.push(selData);}})}}});

4.json為list_josn.json

下面是json中的數(shù)據(jù)

{"lists":[{"id":"1","author":"小華","name":"《春天來了》","price":"23","time":"1998-03-12"},{"id":"2","author":"老舍","name":"《濟南的冬天》","price":"32","time":"1956-12-09"},{"id":"3","author":"朱自清","name":"《背影》","price":"40","time":"1943-09-12"}]}
