Page({

    onReady() {

        this.videoCtx = wx.createVideoContext(‘myVideo’)

    },

    bindSendDanmu: function () {

        this.videoContext.sendDanmu({

            text: this.inputValue,

            color: getRandomColor()

        })

    }

})

一旦我点击发送弹幕按钮就报错：

thirdScriptError

    Cannot read property ‘sendDanmu’ of undefined;at pages/cover-view/cover-view page bindSendDanmu function

    TypeError: Cannot read property ‘sendDanmu’ of undefined

如果使用 wx.createVideoContext(‘myVideo’).sendDanmu({}) 就没问题
