javascript求救！！！！

jsp页面怎么用javascript调用系统录音，然后上传到服务器？？？？

解决方案 »

  1.   


        WshShell = new ActiveXObject("Wscript.Shell")
        WshShell.Run("sndrec32.exe")
      

  2.   

    Wscript.Shell 这个就不用来了, 一般人不会开这个权限.可以参考一下某个邮箱里面发送语音邮件的功能, 好似是用flash做的.

        这是Applet程序在网页中调用。   
      <html>   
      <applet   code=Capture.class width=320   height=270></applet>   
        
      </html>
      

  4.   

    不过<applet  code=Capture.class width=320  height=270> </applet>  
    已经过时了   code要的地址谁知道啊  好像有地址就能调用上面的那个类了  不过  不知道地址是什么啊  大虾们  帮帮忙啊
      

  5.   

    可以用activex， 也可以用flash， 像很多交友网站，比如51就可以调用本地摄像头拍照。
