3.v-for='(item,index) in myData' 遍历数组 {{index}} {{item.name}} {{item.age}} 适用于vue版本2.0

4.v-for='(item,index,key) in myData' 遍历json {{index}} {{item}} {{key}} 适用于vue版本2.0

5.v-on:click="currentUser=index" 直接绑定点击事件改变逻辑层的数据 currentUser这里是逻辑层的数据

6.v-show="myData.length!=0" v-show根据后面的布尔值觉得显示还是隐藏可直接用逻辑层的数据进行判断

7.<div class="modal" role='dialog' id="layer"> modal dialog为遮罩框 id用来联系触发元素

8. data-toggle='modal' 交替显示隐藏遮罩框 data-target='#layer' 确定目标模态框
