场景描述：
父组件触发某个事件改变子组件的值

  return (
      <PageHeaderWrapper title={false}>
        <Card bordered={false}>
          <div className={styles.tableList}>
          </div>
          <div className={styles.tableListForm}>{this.addForm()}</div>
          <Table
            // scroll={{ x: 2200 }} 
            rowKey={record => record.id}
            loading={loading}
            dataSource={gridData.list}
            columns={columns}
            pagination={paginationProps}
            onChange={this.handlePageChange}
          />
        </Card>
        <DoctorEditForm
          {...editMethods}
          proList={proList}
          cityList={cityListEdit}
          hosList={hospitalListEdit}
          departList={departListEdit}
          workTimeList={workTimeList}
          modalVisible={showEdit}
          curHospital={curHospital}
          values={hospital}
          preBinds={preBinds}
        />
        {/* <AuditEditForm  {...editMethods}  auditValue={auditValue}  modalVisible={showAudit}/> */}

      </PageHeaderWrapper>
    );

constructor(props) {
super(props);
this.state = {
isAudit: 0
}
}
注：此处不用componentDidMount的原因，加载父组件的时候子组件同时被执行，因此在父组件触发事件之前componentDidMount已经被执行过了
componentDidUpdate(prevProps) {
const { values: { isAudit } } = prevProps
const { values: { isAudit:newIsAudit } } = this.props
if (isAudit!=newIsAudit) {
this.setState({
isAudit:newIsAudit
})
}
}
