vue加载本地json数据

json数据存放在除static静态文件夹中

这种方法暂时还没出来，若有大神知道，可否能指导一二

json数据存放在static静态文件夹中

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      style="width:100%"    ></el-table>

读取本地json文件并分页显示

功能实现

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h5页面分页显示（这里以3行数据分页）

student.json数据如下

[  {"stuId":1,"stuName":"李华","stuSex":"男","stuAge":20},  {"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},  {"stuId":6,"stuName":"李晔","stuSex":"女","stuAge":20},  {"stuId":7,"stuName":"钱国强","stuSex":"男","stuAge":21},  {"stuId":8,"stuName":"张三","stuSex":"男","stuAge":22},  {"stuId":9,"stuName":"唐毓民","stuSex":"男","stuAge":25},  {"stuId":10,"stuName":www.easck.com"玛丽亚","stuSex":"女","stuAge":21},  {"stuId":11,"stuName":"李家明",gwCMuCny"stuSex":"男","stuAge":21}]

h5代码如下

<body>  <div id ="app" v-cloak>    <table border="1px" style="width: 400px;" class="table table-striped table-bordered table-hover table-condensed">      <thead>         <tr>           <th>序号</th>           <th>姓名</th>           <th>性别</th>           <th>年龄</th>         </tr>      </thead>     <tr v-for="student in stuData">       <td>{{ student.stuId }}</td>       <td>{{ student.stuName }}</td>       <td>{{ student.stuSex }}</td>       <td>{{ student.stuAge }}</td>     </tr>    </table>    <!-- 用无序列表做一个页码导航条-->    <ul>      <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  @click="prePage"> < </a></li>      <li v-for="(value,index) in pageNumber">       <a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  @click="thisPage(index)">{{ index+1 }}</a>      </li>      <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  @click="nextPage"> > </a></li>    </ul>  </div></body>

css样式

<style>  [v-cloak]{    display: none;  }  ul{   margin-left: 20px;  }  ul li{    float: left;    list-style: none;    background-color: aqua;  }  ul li a{    text-decoration: none;    padding: 5px 15px;    color:black;    border: 1px solid white;  }  a:hover{    background: tomato;  }<www.easck.com;/style>

js代码

<script>   //创建Vue实例,得到 ViewModel   var app = new Vue({    el: '#app',    data: {     list:[],     pageSize:3,//每页大小     currentPage:0 //当前页码    },/*数据*/    mounted(){     //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: {      //上一页      nextPage: function(){            if (this.currentPage == this.pageNumber - 1) return;            this.currentPage++;        },        //下一页        prePage: function(){            if (this.currentPage == 0) return;            this.currentPage--;        },        //页码        thisPage: function(index){           this.currentPage = index;        }    },/*执行触发函数*/    computed: {      //分页数据      stuData: function(){            let left = this.currentPage*this.pageSize;            let right = Math.min((this.currentPage+1)*this.pageSize, this.list.length)            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*/   });  </script>
