        headerRight: <RightGroup navigation={navigation} cback={()=>navigation.state.params.name()}  path=‘projectTarget‘ title="目标" data={{ type:1,name:"固定投资目标"}} />
    })

componentDidMount(){
        this.fetch();
        //设置数据
        this.props.navigation.setParams({name:this.test});
    }
    test = () => {
        alert(123);
    }
