先赋值liveList，然后定义data-id="{{index}}"
<view class="liveTv" wx:for='{{liveList}}' wx:key="index"> <image class="liveImg" data-id="{{index}}" data-img_url="{{item.img_url}}" bindtap="gotoTv" mode="widthFix" src="{{item.img_url}}"></image> </view> <video src="{{videoLink}}" direction="0" controls="true" id="videoId" bindfullscreenchange="leaveVideo" class='videoCenter'></video> data:{ liveList: [], videoLink: null, } gotoTv(e){ var that = this console.log(e.currentTarget.dataset.id) console.log(this.data.liveList[e.currentTarget.dataset.id].post_source) //打印视频连接 this.setData({ videoLink: this.data.liveList[e.currentTarget.dataset.id].post_source //获取视频连接 }) console.log(this.data) this.videoContext.requestFullScreen() setTimeout(function() { that.videoContext.play() }, 500) }, leaveVideo: function() { this.videoContext.pause() this.setData({ videoLink: null }) }, onReady: function() { this.videoContext = wx.createVideoContext('videoId') },
