我们为表单控件定义了三种校验状态,为 `<FormItem>` 定义 `validateStatus` 属性即可。
2015-06-15 20:24:01 +08:00
2015-10-25 11:35:03 +08:00
validateStatus: ['success', 'warning', 'error', 'validating']。

另外为输入框添加反馈图标,设置 `<FormItem>``hasFeedback` 属性值为 `true` 即可。
2015-07-07 11:25:16 +08:00
2015-10-29 08:41:51 +08:00
**注意**: 反馈图标只对 `<Input />` 有效。
