JAVASCRITP在DONET网页中控制WMediaPlay控件(2)

javascript
 1
 2            //是否静音
 3            function IsVolue()
 4            {
 5                if (document.Form1.wmplay.settings.mute)
 6                {
 7                    document.Form1.wmplay.settings.mute = false;
 8                    document.Form1.volue.value ="静音";
 9                }
10                else
11                {

13                    document.Form1.volue.value ="不静音";
14                }
15            }
16            //增加音量
17            function AddVolue()
18            {
19                document.Form1.wmplay.settings.volume = document.Form1.wmplay.settings.volume +10;
20                if (document.Form1.wmplay.settings.volume == 100)
21                {
22                    alert("已调到最大音量了!请保护好你的耳朵!");
23                }
24            }
25            //减少音量
26            function ReduceVolue()
27            {
28                document.Form1.wmplay.settings.volume = document.Form1.wmplay.settings.volume - 10;
29                if (document.Form1.wmplay.settings.volume == 10)
30                {
31                    alert("在调下去就听不到声音了!");
32                }
33            }
34            
35            //当前进度时间
36            function CurrentTime()
37            {
38                document.all.item("CTime").innerHTML = document.all.item("wmplay").controls.currentPositionString;
39                setTimeout('CurrentTime()',1000);
40            }
41            //播放的状态  (3,play),)(2,暂停)(1,停止)
42            function change()
43            {
44                switch(document.all.item("wmplay").PlayState)
45                {
46                    case 1:
47                        info.innerHTML = "<font color=#ffffff>暂停</font>";
48                    break;
49                    case 2:
50                        info.innerHTML = "<font color=#ffffff>停止</font>";
51                        break;
52                    case 3:
53                        document.all.item("TotalTime").innerHTML = document.all.item("wmplay").currentMedia.durationString;
54                        CurrentTime();
55                        break;
56                    case 6://实际上是缓冲
57                        info.innerHTML = "正在播放";
58                        break;
59                    case 7:
60                        info.innerHTML = "";
61                        break;
62                    case 8:
63                        info.innerHTML = "<center>影片播放结束，谢谢观看！</center>";
64                        break;
65                    case 9:
66                        info.innerHTML = "正在缓冲..";
67                        break;
68                    case 10:
69                        info.innerHTML = "缓冲完成,准备播放";
70                        break;
71                }
72            }
73        //全屏
74        function full()
75        {
76            document.Form1.wmplay.fullScreen = 1;
77        }

实现了其他的控件功能,不过在使用mms协议时,不能实时显示.

1<SCRIPT language="javascript" event="PlayStateChange()" for="wmplay">
2<!--
3    change();    
4-->

这个是状态发生改变时,调用相应的方法
