2017.12.07 React組件嵌套以及for循環渲染子組件

1.嵌套組件之父組件的定義：

export default class Examines extends Component{

    componentWillMount()  {
        console.log("aaaaaaaa");

        var data2={

            action:"queryTaskOfManager"
        };
        Common.getData(JSON.stringify(data2),function (ret) {
            alert(ret);
            var data3={
                name:ret.msg.name,

            };
            alert(data3);
        });

    }

    render(){
        var items = [];
        for (var i = 0; i < 10; i++) {
            items.push(<OneTask/>); //這裏父組件Examines，嵌套了子組件<OnTask/>
        }
        return(

            <div style={{ background: '#ECECEC', padding: '30px' }} onLoad={this.componentWillMount}>
            <Row gutter={16}>

                {items}
            </Row>
            </div>

        );

    }

}

 

2.嵌套組件之子組件的定義：

class OneTask extends React.Component{
    constructor(props) {

        super(props);
        this.state = {
            date: '',
            person:'',
            work:'',
            applyclass:'',
            otherinfo:'',
            applytime1:'',
            applytime2:'',
            timecount:''
        }
    }
    render(){
        return (
            <Col span={8}>
                <Card title="請假申請單" bordered={false}>
                    <p>申請人：{this.state.person}</p>
                    <p>申請時間：{this.state.date}</p>
                    <p>崗位：{this.state.work}</p>
                    <p>請假類型：{this.state.applyclass}</p>
                    <p>請假備註：{this.state.otherinfo}</p>
                    <p>請假時間：{this.state.applytime1}到,{this.state.applytime2}</p>
                    <p>共請假：{this.state.timecount}天</p>
                    <Row gutter={16}>
                        <Col span={12}>
                            <Button type="primary"  id="apply">批准</Button>

                        </Col>
                        <Col span={12}>
                            <Button type="danger" style={{marginLeft:30}} id="cancel">不批</Button>
                        </Col>
                    </Row>
                </Card>
            </Col>

        )}
}

 

3.for循環渲染子組件：

render(){
        var items = [];
        for (var i = 0; i < 10; i++) {
            items.push(<OneTask/>);
        }
        return(

            <div style={{ background: '#ECECEC', padding: '30px' }} onLoad={this.componentWillMount}>
            <Row gutter={16}>

                {items}
            </Row>
            </div>

        );

    }
