1,href和src的區別:href有「鏈接,引用」之意,指二者的鏈接關係,如<a href=""></a>,<link href="**.css"/>;javascript
src有「獲取」之意,指拿來使用,如<img src="./**.jpg"/>。css
2,HTML5標籤html
1>,<video>,視頻標籤,僅支持ogg,mpeg4,webm格式視頻html5
<video scr="' width="" height="" controls="controls"></video>支持寬,高,開始暫停音量控件;java
<video>web
<source src="**.ogg" type="video/ogg">瀏覽器
<source src="**.mp4" type="video/mp4">ide
Your browser does not support the video tag.spa
</video>若有多個視頻來源,source標籤引用多個視頻來源,瀏覽器選擇支持的格式,當瀏覽器不支持video標籤是,顯示內部文本。code
video支持DOM控制,提供play(),pause()方法,提供屬性paused
<!DOCTYPE html> <html> <body> <div style="text-align:center;"> <button onclick="playPause()">播放/暫停</button> <button onclick="makeBig()">大</button> <button onclick="makeNormal()">中</button> <button onclick="makeSmall()">小</button> <br /> <video id="video1" width="420" style="margin-top:15px;"> <source src="/example/html5/mov_bbb.mp4" type="video/mp4" /> <source src="/example/html5/mov_bbb.ogg" type="video/ogg" /> Your browser does not support HTML5 video. </video> </div> <script type="text/javascript"> var myVideo=document.getElementById("video1"); function playPause() { if (myVideo.paused) myVideo.play(); else myVideo.pause(); } function makeBig() { myVideo.width=560; } function makeSmall() { myVideo.width=320; } function makeNormal() { myVideo.width=420; } </script> </body> </html>
2>,<audio>音頻標籤,用法類比<video>
3>,html5好難啊。。。
