jQuery不可以使用play()方法,但js是可以的:
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:
$(
‘#videoId‘
).get(
0
).play();
最简单的方法实现Play和Pause:
$(
‘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:
<video width=
"640"
height=
"360"
src=
"http://www.youtube.com/demo/google_main.mp4"
controls autobuffer>
<p> Try
this
page in Safari
4
! Or you can
<a href=
"http://www.youtube.com/demo/google_main.mp4"
>download the video</a> instead.</p>
</video>
自动播放:
<video src=
"abc.mov"
autoplay>
</video>
使用poster在视频无法加载时显示图片:
<video width=
"640"
height=
"360"
src=
"http://www.youtube.com/demo/google_main.mp"
autobuffer controls poster=
"whale.png"
>
<p>Try
this
page in Safari
4
! Or you can <a href=
"http://www.youtube.com/demo/google_main.mp4"
>download the video</a> instead.</p>
</video>
一个比较简洁的例子:
<script type=
"text/javascript"
>
function vidplay() {
var video = document.getElementById(
"Video1"
);
var button = document.getElementById(
"play"
);
if
(video.paused) {
video.play();
button.textContent =
"||"
;
}
else
{
video.pause();
button.textContent =
">"
;
}
}
function restart() {
var video = document.getElementById(
"Video1"
);
video.currentTime =
0
;
}
function skip(value) {
var video = document.getElementById(
"Video1"
);
video.currentTime += value;
}
</script>
</head>
<body>
<video id=
"Video1"
>
// Replace these with your own video files.
<source src=
"demo.mp4"
type=
"video/mp4"
/>
<source src=
"demo.ogv"
type=
"video/ogg"
/>
HTML5 Video is required
for
this
example.
<a href=
"demo.mp4"
>Download the video</a> file.
</video>
<div id=
"buttonbar"
>
<button id=
"restart"
onclick=
"restart();"
>[]</button>
<button id=
"rew"
onclick=
"skip(-10)"
><<</button>
<button id=
"play"
onclick=
"vidplay()"
>></button>
<button id=
"fastFwd"
onclick=
"skip(10)"
>>></button>
</div>
