弹幕结构
每一个弹幕是一个对象,多个弹幕组成的数组就是弹幕库,通常只需要text
就可以发送一个弹幕,其余都是非必要参数
js
{
text: '', // 弹幕文本
time: 10, // 弹幕时间, 默认为当前播放器时间
mode: 0, // 弹幕模式: 0: 滚动(默认),1: 顶部,2: 底部
color: '#FFFFFF', // 弹幕颜色,默认为白色
border: false, // 弹幕是否有描边, 默认为 false
style: {}, // 弹幕自定义样式, 默认为空对象
}
全部选项
只有danmuku
是必须的参数,其余都是非必填
js
{
danmuku: [], // 弹幕数据
speed: 5, // 弹幕持续时间,范围在[1 ~ 10]
margin: [10, '25%'], // 弹幕上下边距,支持像素数字和百分比
opacity: 1, // 弹幕透明度,范围在[0 ~ 1]
color: '#FFFFFF', // 默认弹幕颜色,可以被单独弹幕项覆盖
mode: 0, // 默认弹幕模式: 0: 滚动,1: 顶部,2: 底部
modes: [0, 1, 2], // 弹幕可见的模式
fontSize: 25, // 弹幕字体大小,支持像素数字和百分比
antiOverlap: true, // 弹幕是否防重叠
synchronousPlayback: false, // 是否同步播放速度
mount: undefined, // 弹幕发射器挂载点, 默认为播放器控制栏中部
heatmap: false, // 是否开启热力图
width: 512, // 当播放器宽度小于此值时,弹幕发射器置于播放器底部
points: [], // 热力图数据
filter: () => true, // 弹幕载入前的过滤器,只支持返回布尔值
beforeEmit: () => true, // 弹幕发送前的过滤器,支持返回 Promise
beforeVisible: () => true, // 弹幕显示前的过滤器,支持返回 Promise
visible: true, // 弹幕层是否可见
emitter: true, // 是否开启弹幕发射器
maxLength: 200, // 弹幕输入框最大长度, 范围在[1 ~ 1000]
lockTime: 5, // 输入框锁定时间,范围在[1 ~ 60]
theme: 'dark', // 弹幕主题,支持 dark 和 light,只在自定义挂载时生效
OPACITY: {}, // 不透明度配置项
FONT_SIZE: {}, // 弹幕字号配置项
MARGIN: {}, // 显示区域配置项
SPEED: {}, // 弹幕速度配置项
COLOR: [], // 颜色列表配置项
}
生命周期
来自用户输入的弹幕:
beforeEmit -> filter -> beforeVisible -> artplayerPluginDanmuku:visible
来自服务器的弹幕:
filter -> beforeVisible -> artplayerPluginDanmuku:visible
▶ Run Code
js
// 保存到数据库
function saveDanmu(danmu) {
return new Promise(resolve => {
setTimeout(() => {
resolve(true);
}, 1000);
})
}
var art = new Artplayer({
container: '.artplayer-app',
url: '/assets/sample/video.mp4',
plugins: [
artplayerPluginDanmuku({
danmuku: '/assets/sample/danmuku.xml',
// 这是用户在输入框输入弹幕文本,然后点击发送按钮后触发的函数
// 你可以对弹幕做合法校验,或者做存库处理
// 当返回true后才表示把弹幕加入到弹幕队列
async beforeEmit(danmu) {
const isDirty = (/fuck/i).test(danmu.text);
if (isDirty) return false;
const state = await saveDanmu(danmu);
return state;
},
// 这里是所有弹幕的过滤器,包含来自服务端的和来自用户输入的
// 你可以对弹幕做合法校验
// 当返回true后才表示把弹幕加入到弹幕队列
filter(danmu) {
return danmu.text.length <= 200;
},
// 这是弹幕即将显示的时触发的函数
// 你可以对弹幕做合法校验
// 当返回true后才表示可以马上发送到播放器里
async beforeVisible(danmu) {
return true;
},
}),
],
});
// 弹幕已经出现在播放器里,你可以访问到弹幕的dom元素里
art.on('artplayerPluginDanmuku:visible', danmu => {
danmu.$ref.innerHTML = 'ଘ(੭ˊᵕˋ)੭: ' + danmu.$ref.innerHTML;
})

});
mount
在初始化弹幕插件的时候,是可以指定弹幕发射器的挂载位置的,默认是挂载在控制栏的中部,你也可以把它挂载在播放器以外的地方。 当播放器全屏的时候,发射器会自动回到控制栏的中部。假如你挂载的地方是亮色的话,建议把 theme
设置成 light
,否则会看不清。
▶ Run Code
js
var $danmu = document.querySelector('.artplayer-app');
var art = new Artplayer({
container: '.artplayer-app',
url: '/assets/sample/video.mp4',
fullscreenWeb: true,
plugins: [
artplayerPluginDanmuku({
mount: $danmu,
theme: 'dark',
danmuku: '/assets/sample/danmuku.xml',
}),
],
});
// 也可以手动挂载
// art.plugins.artplayerPluginDanmuku.mount($danmu);
option
用于获取当前弹幕配置
▶ Run Code
js
var art = new Artplayer({
container: '.artplayer-app',
url: '/assets/sample/video.mp4',
plugins: [
artplayerPluginDanmuku({
danmuku: '/assets/sample/danmuku.xml',
