本篇内容主要讲解“vue怎么加载本地json数据”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“vue怎么加载本地json数据”吧!
这种方法暂时还没出来，若有大神知道，可否能指导一二
1、编写好json 数据，按照这个格式编写json数据
2、安装axios 安装方法：npm install axios
3、配置axios，在main.js中引用axios，如下图所示
4、就可以调用json数据了，也可以加上一句：console.log(this.fieldParams)在控制台打印数据
表格代码：
<el-table :data="fieldParams" border > </el-table>
通过axios异步加载技术读取本地的json文件内容，并通过vue.js处理数据在h6页面分页显示（这里以3行数据分页）

{"stuId":2,"stuName":"张国伟","stuSex":"男","stuAge":22},
{"stuId":3,"stuName":"刘艳","stuSex":"女","stuAge":19},
{"stuId":4,"stuName":"李小燕","stuSex":"女","stuAge":22},
{"stuId":5,"stuName":"张鹏","stuSex":"男","stuAge":26},

//创建Vue实例,得到 ViewModel
var app = new Vue({

},/*数据*/

//异步加载json数据
axios.get('/json/student.json',{}).then(function(response){
app.list=response.data;
});
},/*自动加载函数*/
methods: {

return this.list.slice(left, right);//取出一页数据
},
//共有多少页
pageNumber: function(){
if(this.list.length<=this.pageSize){
return 1;
}
return Math.ceil(this.list.length / this.pageSize);
}
},/*动态计算属性*/
});
