npm install rc-form-array --save

使用

import { createFormArray } from 'rc-form-array';

创建

createFormArray(list: T[], minLen = 0)

示例：this.setState({ students: students.add({ name: 'xiaoming', age: 18 }) });

删除

delete(...keys: number[]): FormArray

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

set(key: number, fn: (item: T) => T): FormArray

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
})(

)
)
