Video小程序播放视频的组件。
wx.createVideoContext(videoId, this)创建并返回 video 上下文 videoContext 对象。在自定义组件下,第二个参数传入组件实例this,以操作组件内 <video/> 组件
API注:
- video 组件是由客户端创建的原生组件,它的层级是最高的,不能通过 z-index 控制层级。
2.不能scroll-view、swiper、picker-view、movable-view 中使用 video 组件。
3.css 动画对 video 组件无效。

.js代码
function getRandomColor () {
let rgb = []
for (let i = 0 ; i < 3; ++i){
let color = Math.floor(Math.random() * 256).toString(16)
color = color.length == 1 ? '0' + color : color
rgb.push(color)
}
return '#' + rgb.join('')
}
Page({
onReady: function (res) {
this.videoContext = wx.createVideoContext('myVideo')
},
inputValue: '',
data: {
src: '',
danmuList: [
{
text: '第 1s 出现的弹幕',
color: '#ff0000',
time: 1
},
{
text: '第 3s 出现的弹幕',
color: '#ff00ff',
time: 3
}
]
},
bindInputBlur: function(e) {
this.inputValue = e.detail.value
},
bindButtonTap: function() { //视频下载
var that = this
wx.chooseVideo({
sourceType: ['album', 'camera'],
maxDuration: 60,
camera: ['front','back'],
success: function(res) {
that.setData({
src: res.tempFilePath
})
}
})
},
bindSendDanmu: function () {
this.videoContext.sendDanmu({
text: this.inputValue,
color: getRandomColor()
})
},
videoErrorCallback: function(e) {
console.log('视频错误信息:');
console.log(e.detail.errMsg);
}
})
结果为:
