前言
当前 Antd 版本：5.14.0
Antd 自定义表单控件
自定义或第三方的表单控件，也可以与 Form 组件一起使用。只要该组件遵循以下的约定：
- 提供受控属性
value或其它与valuePropName的值同名的属性。- 提供
onChange事件或trigger的值同名的事件。
也就是说我们的自定义组件想要和 Antd 的 Form 组件搭配使用，实现统一的表单检验等行为，我们只需要让我们的自定义组件向外提供一个 value 属性，和一个 onChange 事件（用于更新 value 值）即可。明白了这点，接下来我们就自定义一个表单控件，用于选择 Icon 图标。
Icon 选择器的结构分析
我们的 Icon 选择器由 2 部分组成：
Input组件：用于显示选中 Icon 图标的名称，同时也由 3 部分构成suffix：是一个清除按钮，可以清除选择addonAfter：展示当前选中图标的预览效果- Input主体区域：显示选中 Icon 图标的名称
Popover组件：用于展示所有可选择的 Icon 图标，由 2 部分构成- 最上面是一个
Segmented分段控制器：用于切换图标风格 - 下面是一个可滚动容器，里面存放对应风格的图标
- 最上面是一个

最后在 Form 组件里面使用，并验证下效果
import { PlusOutlined } from '@ant-design/icons';
import {
ModalForm,
ProForm,
ProFormDateRangePicker,
ProFormSelect,
ProFormText,
} from '@ant-design/pro-components';
import { Button, Form, message } from 'antd';
import PriceInput from './components/PriceInput'
import IconSelect from './components/IconSelect';
const waitTime = (time: number = 100) => {
return new Promise((resolve) => {
setTimeout(() => {
resolve(true);
}, time);
});
};
export default () => {
const [form] = Form.useForm<{ name: string; company: string }>();
return (
<ModalForm>
title="新建表单"
form={form}
onFinish={async (values) => {
await waitTime(2000);
message.success('提交成功');
return true;
}}
>
<Form.Item name="icon" label="图标" rules={[{ required: true, message: '请选择图标' }]}>
<IconSelect />
</Form.Item>
</ModalForm>
);
};
