我想使用JavaScript来控制嵌入式Windows Media Player,以及访问播放器公开的任何属性.我在网上找到了一些hacky示例,但没有具体的内容.
我真的需要访问播放,暂停,停止,搜索,全屏等.我还想访问播放器正在播放的任何事件.
帮助会非常棒(我已经有了Flash等效,只有你知道),谢谢！
API需要Internet Explorer本机的ActiveX连接,或者可以使用
plugin for Firefox.
这是一个可以帮助您入门的示例页面.
<html>
<head>
<title>so-wmp</title>
<script>
onload=function() {
player = document.getElementById("wmp");
player.URL = "test.mp3";
};
function add(text) {
document.body
.appendChild(document.createElement("div"))
.appendChild(document.createTextNode(text));
};
function handler(type) {
var a = arguments;
add(type +" = "+ PlayStates[a[1]]);
};

var PlayStates = {
0: "Undefined",// Windows Media Player is in an undefined state.
1: "Stopped",// Playback of the current media item is stopped.
2: "Paused",// Playback of the current media item is paused. When a media item is paused,resuming playback begins from the same location.
3: "Playing",// The current media item is playing.
4: "ScanForward",// The current media item is fast forwarding.
5: "ScanReverse",// The current media item is fast rewinding.
6: "Buffering",// The current media item is getting additional data from the server.
7: "Waiting",// Connection is established,but the server is not sending data. Waiting for session to begin.
8: "MediaEnded",// Media item has completed playback.
9: "Transitioning",// Preparing new media item.
10: "Ready",// Ready to begin playing.
11: "Reconnecting" // Reconnecting to stream.
