使用jQuery播放/暂停 HTML5视频

我尝试用jQuery控制HTML5视频,两个视频分别在两个tab中,我希望点中tab后,该tab里的视频可以立即播放,而另外tab里的视频能够停止。
我的代码是这样的:

1
2
3
$('#playMovie1').click(function(){
$('#movie1').play();
});

但发现这样不行,而用以下的js是可以的:

1
document.getElementById('movie1').play();

解决方法:
play并不是jQuery的函数,而是DOM元素的函数,所以我们需要通过DOM来调用play,代码如下:

1
$('#videoId').get(0).play();

最简单的方法实现Play和Pause:

1
2
$('video').trigger('play');
$('video').trigger('pause');


点击视频就能播放和暂停

$("video").trigger("play");//for auto play
$("video").addClass('pause');//for check pause or play add a class
$('video').click(function() {
if($(this).hasClass('pause')) {
$("video").trigger("play");
$(this).removeClass('pause');
$(this).addClass('play');
}else{
$("video").trigger("pause");
$(this).removeClass('play');
$(this).addClass('pause');
}
})

静音和取消静音

$('body').find("video").attr('id','video')
var myVid = document.getElementById("video");
$('.sound-icon').click(function() {
//here "sound-icon" is a anchor class.
var sta = myVid.muted;
if(sta ==true) {
myVid.muted =false;
}else{
myVid.muted =true;
}
})

HTML 5中播放视频的方法:

1
2
3
4
<video width="640"height="360"src="http://www.youtube.com/demo/google_main.mp4"controls autobuffer>
<p> Trythispage in Safari4! Or you can
<a href="http://www.youtube.com/demo/google_main.mp4">download the video</a> instead.</p>
</video>

自动播放:

1
2
<video src="abc.mov"autoplay>
</video>

使用poster在视频无法加载时显示图片:

1
2
3
<video width="640"height="360"src="http://www.youtube.com/demo/google_main.mp"autobuffer controls poster="whale.png">
<p>Trythispage in Safari4! Or you can <a href="http://www.youtube.com/demo/google_main.mp4">download the video</a> instead.</p>
</video>
