react export default connect与export default (classname)

const mapstateProps = state =>{

retrun{
...state

}

}

export default connect(mapstateProps,null,null,{withRef：true})(classname)

export default (classname)    该表model 要传递dispatch={this.props.dispatch}

指定组件的ref              refs={ref=>{this.gform=ref}   this.gform 调用

                                    ref={name}   this.refs.name调用
