iview的Input的autofocus属性问题

Question

我用Input组件的自动聚焦属性autofocus

<Input v-model="uid" icon="ios-clock-outline" placeholder="请输入用户编号..." v-show="usershow" style="width: 100%;margin-bottom:5px;" autofocus="true"></Input>

但是总是报错

vue.esm.js:479 [Vue warn]: Invalid prop: type check failed for prop "autofocus". Expected Boolean, got String.

found in

---> <Input>
       <Borrowbook> at F:\iview\src\views\borrowbook.vue
         <ICol>
           <Row>
             <Index> at F:\iview\src\views\index.vue
               <App> at F:\iview\src\app.vue
                 <Root>

说是属性类型错了，但是我用的就是true，实在不知道怎么办了

Answer 1

不能直接传入boolean值，按照下面就对了

<Input placeholder="请输入用户编号..." autofocus></Input>

如果传入布尔值的话，会当成字符串，vue文档也说了需要使用v-bind，简单点就用:就可以使用，这时候就能传入布尔值了

Answer 2

<Input placeholder="请输入用户编号..." :autofocus="true"></Input>

Answer 3

autofocus="autofocus"
