已解决，代码如下：

<view wx:for=’{{detail.video}}’>

    <video id=‘video{{index}}’ src=’{{item}}’ bindplay=‘play’></video>  

</view>

play(e) {

    var id = e.currentTarget.id;

    for (var i = 0; i < this.data.detail.video.length; i++) {

        if (id === ‘video’ + i) {

            console.log(‘播放视频不做处理’);

        } else {

            console.log(‘暂停其他正在播放的视频’);

            this.videoContext = wx.createVideoContext([“video”, i].join(’’), this);

            this.videoContext.pause();

        }

    }

},
