                }  
            ],  
            index: 0,  
            videoCtx: null  
        };  
    },  
    onLoad () {  
    },  
    onReady () {  
        this.videoCtx = uni.createVideoContext('video');  
    },  
    methods: {  
        selectVideo (index) {  
            this.index = index;  
            this.videoCtx.play();  
            this.videoCtx.seek(10);  
        }  
    }  
};
