Question

我现在有一系列录像。当我点击下方和预击阵列负荷的下方或前方录像时,我如何这样做。

 <video id="video" controls autoplay width="1000">
  <source src="videos/test.mp4" type= video/mp4; codecs="avc1.42E01E, mp4a.40.2"  />
  <source src="videos/test.ogv" />
 </video>

<a href="#" onClick="javascript:vidSwap(vidURL[i+]); return false;">next</a>



<script>
var vidURL=["videos/test.ogv","videos/test2.ogv","videos/test3.ogv","videos/test4.ogv","videos/test5.ogv"    ]; // literal array
function vidSwap(vidURL) {
var myVideo = document.getElementsByTagName( video )[0];
myVideo.src = vidURL;
myVideo.load();
 myVideo.play();
}

Answer 1

Using yout code, it ll be something like this. What you need to do is have the video that you loaded on a javascript variable. Then, when you click prev or next you can call a function that will put the correct video number and call it.

<script>
var vidURL=["videos/test.ogv","videos/test2.ogv","videos/test3.ogv","videos"]
var video = 0;

function vidSwap() {
  var myVideo = document.getElementsByTagName( video )[video];
  myVideo.src = vidURL[video];
  myVideo.load();
  myVideo.play();
}


function prevVideo() {
  if(video == 0) {
    video = vidUrl.length;
  }
  else {
    video -= 1;
  }

  vidSwap();
}

function nextVideo() {
  if(video == length) {
    video = 0;
  }
  else {
    video += 1;
  }

  vidSwap();
}

</script>


 <video id="video" controls autoplay width="1000">
  <source src="videos/test.mp4" type= video/mp4; codecs="avc1.42E01E, mp4a.40.2"  />
  <source src="videos/test.ogv" />
 </video>

<a href="#" onClick="javascript:prevVideo(); return false;">prev</a>
<a href="#" onClick="javascript:nextVideo(); return false;">next</a>

引入可节省现有录像指数的变量,然后在你下台/前台时予以增减。

</script>
var i = 0;
<script>

javascript:vidSwap(vidURL[i++])

Answer 4

a. 总结选择;

<a href="#" onClick="return Vids.next();">next</a>
<a href="#" onClick="return Vids.prev();">prev</a>

...

var Vids = (function() {
    var _currentId = -1;
    var _urls = ["videos/test.ogv","videos/test2.ogv","videos/test3.ogv","videos/test4.ogv","videos/test5.ogv"    ]; // literal array
    return {
        next: function() {
            if (++_currentId >= _urls.length)
                _currentId = 0;
             return this.play(_currentId);
        },
        prev: function() {
            if (--_currentId < 0)
                _currentId = _urls.length - 1;
            return this.play(_currentId);
        },
        play: function(id) {
            var myVideo = document.getElementsByTagName( video )[0];
            myVideo.src = _urls[id];
            myVideo.load();
            myVideo.play();
            return false;
       }
    }
})();
