WXSS文件代码如下:
/* pages/video/video.wxss */
.video {
width: 750rpx;
}
.danmu-box {
display: flex;
border: gray solid 1rpx;
border-radius: 3%;
margin: 0rpx 5rpx;
}
.danmu {
display: flex;
padding-left: 20rpx;
}
.txt {
margin-top: 8rpx;
padding-left: 30rpx;
}
.input {
width: 400rpx;
margin-top: 8rpx;
padding: 0rpx 30rpx;
}
JS文件代码如下:
// pages/video/video.js
// 弹幕随机颜色函数
function getRandomColor() {
const 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('')
}
let video = null
let inputvalue = ""
Page({
data: {
danmuList: [
{
text: '微信小程序',
time: 1,
color: '#ffffff'
},
{
text: 'video组件',
time: 2,
color: '#000000'
},
{
text: '弹幕功能',
time: 3,
color: '#0086ea'
}
]
},
Danmu(event) {
inputvalue = event.detail.value
},
sendDanmu() {
video.sendDanmu({
text: inputvalue,
color: getRandomColor()
})
},
// 生命周期函数--监听页面初次渲染完成
onReady: function () {
video = wx.createVideoContext('danmucontext')
},
})
