安装
npm install rc-form-array --save
使用
import { createFormArray } from 'rc-form-array';
创建
createFormArray<T>(list: T[], minLen = 0)
示例：this.state = { students: createFormArray([]) };
新增
add(...newItems: T[]): FormArray<T>
示例：this.setState({ students: students.add({ name: 'xiaoming', age: 18 }) });
删除
delete(...keys: number[]): FormArray<T>
示例：this.setState({ students: students.delete(0) });
获取
get(key: number): T
示例：students.get(0)
更新
set(key: number, item: T): FormArray<T>
set(key: number, fn: (item: T) => T): FormArray<T>
示例：this.setState({ students: students.set(0, { name: 'xiaohong', age: 18 }) });
this.setState({ students: students.set(0, (student) => ({ ...student, name: 'xiaohong' })) });
渲染
render(fn: (value: T, key: number, index: number) => any)
示例：
students.render((item, key, index) =>
getFieldDecorator(`students[${key}].name`, {
initialValue: item && item.name
})(
<Input/>
)
)
