## 需求 ##

多个视频要用同一个进度条控制播放暂停  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dhbmd3ZWlzY3Nkbg_size_16_color_FFFFFF_t_70]

## 进度条 ##

这个可以用antd的Slider组件

<Slider
    	marks={ marks}
    	max={ maxTime}
    	defaultValue={ timeValue}
    	value={ timeValue}
    	tooltipVisible={ false}
    	onAfterChange={ (v) => handleAfterChange(v)}
    	onChange={ (value) => handleSliderValue(value)}
    />

## 视频播放videojs ##

## 初始化多个videojs ##

// 初始化videoJs
    	const handleInitVideo = () => { 
    		// debugger
    		// console.log({masterList})
    		videoList.map(v => { 
    			const { id, nickname } = v
    			// console.log(document.getElementById(`play${id}`))
    				if (document.getElementById(`play${ id}`) && !current[`play${ id}`] && nickname) { 
    						current[`play${ id}`] = videoJs(`play${ id}`, {  fluid: true }, function() { 
    											console.log(`1111play${ id}`);
    											// current[`play${id}`].play();
    									});
    									current[`play${ id}`].src([{ src:v.mediaUrl, type:v.sourceType}]) 
    							}
    							return
    			// }
    		})
    	}

## 多个视频一起播放暂停 ##

// 遍历每个video
    	const handleEveryVideo = (list, fun, time) => { 
    		for (let i in list) { 
    			if (i !== 'timer' && list[i]) { 
    				// console.log('list[i]', fun,i, list[i])
    				switch (fun) { 
    					case 'play': // 播放
    						list[i].play();
    						break;
    					case 'pause': // 暂停
    						list[i].pause();
    						break; // 设置时间点
    					case 'currentTime':
    						list[i].currentTime(time);
    						break;
    					case 'dispose': // 销毁
    						list[i].dispose();
    						break;
    
    					default:
    						break;
    				}
    			}
    		}
    	}
