| ## FAQ |
|
|
| ### Why Input lose focus when change `prefix/suffix/showCount` |
|
|
| 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: |
|
|
| ```jsx |
| const suffix = condition ? <Icon type="smile" /> : <span />; |
| |
| <Input suffix={suffix} />; |
| ``` |
|
|
| ### 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. |
