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:
