##API##

###videoplyer 方法###

play([showControllBar]) 播放视频

@showControllBar [boolean :false] 是否显示控制板,默认为false,主要配合pause使用。

var videoplayer = photofigure(imgdata,2);
videoplayer.play();
//or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){
		//use play method
        videoObj.play();
		//user video Element default method
		videoElement.play();
    },
});

pause([hideControllBar]) 暂停视频

@hideControllBar [boolean:false] 是否隐藏控制面板,默认为false,不隐藏。

var videoplayer = photofigure(imgdata,2);
videoplayer.pause();
//or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){
		//use pause method
        videoObj.pause();
		//user video Element default method
		videoElement.pause();
    },
});

fullScreen() 进入全屏模式

var videoplayer = photofigure(imgdata,2);
videoplayer.fullScreen();
//or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){

		//use fullScreen method
        videoObj.fullScreen();

    },
});

unFullScreen() 退出全屏模式

var videoplayer = photofigure(imgdata,2);
videoplayer.unFullScreen();
//or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){
		//use unFullScreen method
        videoObj.unFullScreen();
    },
});

setCurrentTime(newTime) 设置当前播放点,单位:秒

  var videoplayer = photofigure(imgdata,2);
  videoplayer.setCurrentTime(23);
  //or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){
      //use video element set currentTime
      videoElement.currentTime=23
      //or
      //set currentTime
      videoObj.setCurrentTime(23);
    },
});

getContiune() {boolean} 获取是否可以连续的值

timeupdate(callback) 监控更新时间,时间间隔为 1s

var videoplayer = photofigure(imgdata,2);
videoplayer.timeupdate(function(currenTime){
	console.log('currenTime:',currenTime)	
});
//or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){
		//use timeupdate method
        videoObj.timeupdate(function(currenTime){
			console.log('currenTime:',currenTime)
		});
    },
});

待整理。。。


chrome55+,系统全屏时,会有下载按钮,解决方式是添加css

video::-internal-media-controls-download-button {
display:none;
}

video::-webkit-media-controls-enclosure {
overflow:hidden;
}

video::-webkit-media-controls-panel {
width: calc(100% + 30px); /* Adjust as needed */
}

##videoPlayer Events事件方法##

videoObj.on('next',function) 当点击next时,触发

var videoplayer = photofigure(imgdata,2);
videoplayer.on('next',function(){
	console.log('switch next one');
})
//or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){
		//use next event
        videoplayer.on('next',function(){
			console.log('switch next one');
		})
    },
});

videoObj.on('continue',function) 当点击连播时,触发

var videoplayer = photofigure(imgdata,2);
videoplayer.on('continue',function(currentStatus){
	console.log('can contnue play:',currentStatus);
})
//or
var videoplayer2=videoPlayer('mod_player2',{
    success:function(videoElement,node,videoObj){
		//use continue event
        videoplayer.on('continue',function(currentStatus){
			console.log('can contnue play:',currentStatus);
		})
    },
});
