js

bindPlayCallBack: function (e) {
    console.log(‘当前视频‘, e.target.id);
    var current_video = e.target.id;
    // 获取所有的video
    console.log(‘所有视频‘, this.data.index_info.video);
    var that = this;
    let video = that.data.index_info.video;
    for (var i in video) {
        var index_video = ‘video_‘ + video[i].id;
        var videoContextPrev = wx.createVideoContext(index_video);
        if (current_video != index_video) {
            // 暂停其他的
            videoContextPrev.pause();
        }
    }
}

这里用到了，循环json数组的用法。

小程序多视频播放，避免同时播放
