vue与bootstrap实现简单用户信息添加删除功能

本文实例为大家分享了vue与bootstrap实现用户信息添加删除操作的具体代码，供大家参考，具体内容如下

小记：

1.v-model=""    用于input表单双向数据绑定  逻辑层跟渲染层双向绑定

2.v-on:click='add()'     click方法绑定

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

9. data-dismiss='modal'  点击后消失目标元素

效果图：
