从另一个组件调用React VideoJS组件的方法

Question

I am having a react VideoJs component with markers on it in my react project. I have a function called jumpToSpecificMarker in it. I have another component havejumpToSpecificMarker which has names of these markers. All I want to do is call the jumpToSpecificMarker whenever I click listItem of this listview. Currently I am passing action a prop in my onTouchTap event to listItem. I want to pass this as well as fire the jumpToSpecificMarker function when it click listItem. I am using redux to handle the state whenever I click listItem.

Here is my code

export default class PlayerLogic extends Component{
    constructor() {
        super();
        this.state = {
            player : {}
        };
    }
    componentDidMount() {
        var self = this;
        var player = videojs(this.refs.video, this.props.options).ready(function () {
            self.player = this;
            self.player.on('play', self.handlePlay);
        });

        if (this.props.onPlayerInit) this.props.onPlayerInit(player);
         player.markers({
            markerStyle: {},
            markers: [
                {length: 8, startTime: 10, endTime: 15, time: 9.5, text: "Cigarette"},
                {length: 2, startTime: 20, endTime: 25, time: 16, text: "Cigarette"},
                {length: 15, startTime: 30, endTime: 38, time: 23.6, text: "Cigarette"},

            ]
        });

        this.setState({ player: player});
    }

    jumpToSpecificMarker(i) {
        this.state.player.markers.jumpToSpecificMarker(i);
    }

    render() {
        var props = blacklist(this.props, 'children', 'className', 'src', 'type', 'onPlay');
        props.className = cx(this.props.className, 'videojs', 'video-js vjs-default-skin', 'vjs-big-play-centered');


        assign(props, {
            ref: 'video',
            controls: true,
            width: "700", height: "450"
        });


        return (
            <div>
                <video {... props}>
                    <source src={this.props.src} type={this.props.type} id={this.props.id}/>
                </video>
            </div>)

    }
}
const mapStateToProps =(state) =>{
    return {
        tags: state.tagReducer
    };
};

export default connect(mapStateToProps)(PlayerLogic);

I want to call the jumpToSpecificMarker function in above component from the another component which is

class TagListItemDetails extends Component {
    handleButtonClick() {
        browserHistory.push("TagList")
    }

    render() {

        return (
            <MuiThemeProvider>
                <div>
                    <List id="parent-list-tags">
                        <ListItem primaryText="Kitchen" onTouchTap={() => this.props.tagSelected(0)}/>
                        <ListItem primaryText="Beach" onTouchTap={() => this.props.tagSelected(1)}/>
                        <ListItem primaryText="Marriage" onTouchTap={() => this.props.tagSelected(2)}/>
                        <ListItem primaryText="Garden" onTouchTap={() => this.props.tagSelected(3)}/>
                    </List>

Answer 1

Where are you using the self.player property that you defined in this block of code?

componentDidMount() {
    var self = this;
    var player = videojs(this.refs.video, this.props.options).ready(function () {
       self.player = this;
       self.player.on('play', self.handlePlay);
   });

If this line of code is your mistake and you want to write self.state.player = this instead of self.player , please note that this does not update the state.
