## FAQ
2022-04-20 10:33:42 +08:00
### Why Input lose focus when change `prefix/suffix/showCount`
2019-02-20 15:12:29 +08:00
2022-04-20 10:33:42 +08:00
When Input dynamic add or remove `prefix/suffix/showCount` will make React recreate the dom structure and new input will be not focused. You can set an empty `<span />` element to keep the dom structure:
2019-02-20 15:12:29 +08:00
```jsx
const suffix = condition ? < Icon type = "smile" / > : < span / > ;
2019-05-07 14:57:32 +08:00
< Input suffix = {suffix} / > ;
2019-02-20 15:12:29 +08:00
```
2021-03-23 15:03:47 +08:00
### Why TextArea in control can make `value` exceed `maxLength`?
When in control, component should show as what it set to avoid submit value not align with store value in Form.
