input的focus方法使用
对于input组件的focus属性,可以通过设置它为true来获取焦点。在Vue中,可以通过在模板中给input组件指定ref的值,然后使用this.$refs来获取组件,进而设置焦点。例如,可以使用以下代码来设置焦点:
```javascript
<input ref="user_name" />
```
然后在js中,使用如下代码获取并设置焦点:
```javascript
let input = this.$refs.user_name;
input.focus();
```
如果上述方法无效,可以尝试将获取到的组件元素用索引访问,例如:
```javascript
let input = this.$refs["user_name"][0];
input.focus();
```
或者更简洁地写为:
```javascript
this.$refs["user_name"][0].focus();
```
这样,就可以通过设置focus属性来使input框获取焦点了。希望这些方法能够帮助到您解决问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
