首先列表內容還是與之前的列表內容類似,不過此處我們會采用Vue中數據請求的方式來實現數據的增刪。那么我們使用的Vue第三方組件就是vue-resource,vue發起請求的方式與jQuery的ajax相似,組要是請求地址與參數。和方法
首先我們先看到的是列表請求
獲取列表
<table class=" table table-bordered table-hover table-striped"> <thead> <tr> <th>Id</th> <th>Name</th> <th>CTime</th> <th>Operation</th> </tr> </thead> <tbody> <tr v-for="item in list" :key="item.id"> <td>{{ item.id }}</td> <td>{{item.title}}</td> <td>{{item.description}}</td> <td><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click.prevent="del(item.id)">刪除</a></td> </tr> </tbody> </table>
在methods中獲取到的加入獲取數據的list方法,使用get請求
getList(){ this.$http.get('list').then(result=>{ var result =result.body; if(result.code ===200){ this.list = result.data }else{ alert("獲取數據失敗"); } }) },
需要注意的是,使用vue-resource的請求獲取的數據,都封裝在回調數據的body域中,同時我們需要在Vue組件的created生命周期函數中加入使用該方法來渲染頁面
created(){ //在其他方法中調用定義的方法使用this關鍵字 this.getList(); },
增加和刪除元素的方法與此類似,這里給出詳細代碼,不做講解
