微信小程序 - 发送视频弹幕
微信小程序 - 发送视频弹幕
微信小程序官方文档提供了发送视频弹幕的功能,参照其功能做了一些改动,实现可发送用户自定义颜色的弹幕。
function getRandomColor() { var rgb = []; for (var i = 0; i < 3; ++i) { var color = Math.floor(Math.random() * 256).toString(16); color = color.length == 1 ? '0' + color : color; rgb.push(color); } return '#' + rgb.join(''); } Page({ inputValue: '', data: { isRandomColor: true, src: '', numberColor: "#ff0000", danmuList: [{ text: '第 1s 出现的红色弹幕', color: '#ff0000', time: 1 }, { text: '第 2s 出现的绿色弹幕', color: '#00ff00', time: 2 }] }, onLoad: function onLoad() { var _this = this; wx.getSystemInfo({ success: function success(res) { // video标签默认宽度300px、高度225px var windowWidth = res.windowWidth; var videoHeight = 225 / 300 * windowWidth; _this.setData({ videoWidth: windowWidth, videoHeight: videoHeight }); } }); }, onReady: function onReady(res) { this.videoContext = wx.createVideoContext('myVideo'); }, onShow: function onShow() { var _this = this; wx.getStorage({ key: 'numberColor', success: function success(res) { _this.setData({ numberColor: res.data }); } }); }, bindInputBlur: function(e) { this.inputValue = e.detail.value; }, bindSendDanmu: function() { if (this.data.isRandomColor) { var color = getRandomColor(); } else { var color = this.data.numberColor; } this.videoContext.sendDanmu({ text: this.inputValue, color: color }); }, videoErrorCallback: function(e) { console.log('视频错误信息:'); console.log(e.detail.errMsg); }, switchChange: function(e) { this.setData({ isRandomColor: e.detail.value }); }, //跳转到选择颜色的页面 selectColor: function() { wx.navigateTo({ url: '../selectColor/selectColor', success: function(res) { }, fail: function fail() { }, complete: function() { } }); } });

效果如图:
下面是选择弹幕文字颜色的页面,选择文字颜色之后跳转回发送弹幕页面
