在问一个问题之前,我曾经尝试过认真研究这个问题,但看起来我身陷困境,想看看是否有人知道这个问题的明确答案。 我见过一两个类似的问题,但他们似乎没有指出我的问题,或者至少我不明白他们要做什么。

我正在研究一个 RPG 系统音频 PHP 功能, 该功能在被调用时播放音乐, 如果用户没有哑音的音乐选项, 它会使用音频标签 。 (在函数 $song 中, 歌曲被投到第一个参数中 。) 如果此函数被调回真实状态, 那么它会使用一些 Javascript 。 请原谅代码, 因为它有点乱( 对我来说), 但这里使用以下代码, 包括 javascrip 代码 :

function playmusic($song, $resume=false, $loop=true)
 {
  global $baseurl, $loggeduser;

 if ($resume == true)
  {
   $buttons = "
    <button onclick="resetplaytime()" type="button">Reset</button>
    <button onclick="alertplaytime()" type="button">Alert Time</button>";
   $resume = "
    <script type="text/javascript">
      var curmusic_$song = document.getElementById("music_$song");
      var musictime = getcookie("musicplaytime_$song");

     if (musictime != null && musictime != "")
      {
       alert(musictime);
       curmusic_$song.currentTime = musictime; 
      }

      window.onload=settimecookie();

     function getcookie(c_name)
      {
       var i,x,y,ARRcookies=document.cookie.split(";");
      for (i=0;i<ARRcookies.length;i++)
       {
        x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
        y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
        x=x.replace(/^s+|s+$/g,"");
       if (x==c_name)
        {
         return unescape(y);
        }
       }
      }

     function settimecookie()
      {
       var playtime = curmusic_$song.currentTime;
      if (playtime != null && playtime != "")
       {
        document.cookie =  musicplaytime_$song=  + playtime;
       }

       setTimeout("settimecookie()", 50);
      }

     function alertplaytime()
      {
       alert(musictime);
      }

     function resetplaytime()
      {
       curmusic_$song.currentTime=0;
      }

    </script>";
  }

 if ($loop == true)
  {
   $songloop = " loop="true"";
  }

 if ($loggeduser[ mutemusic ] == 0)
  {
   return "
    </table>
    $buttons
    <audio id="music_$song" autoplay="true"$songloop preload="true">
      <source src="$baseurl/boardfiles/effects/$song.ogg" type="audio/ogg" />
      <source src="$baseurl/boardfiles/effects/$song.mp3" type="audio/mp3" />
    </audio>
    $resume
    <table class="brdr" cellpadding="0">";
  }
 }

现在,如果我把将音频标签播放时间设定为 cookie 值的循环的提醒从循环中移除,整个脚本就不管用,除非您使用按钮直接调用一个函数,然后该函数就起作用。

我尝试了几件事情来把这个函数变成一个函数,然后直接调用它(这似乎只是与点击事件有关,但如果你期望它会运行在加载中或自动事件之后,它就会失败。),然后在函数的后半部分移动它(加上设定时间cookie()的加载,因为它会将饼干设置到当前播放时间),而现在我完全没有想法了。

I am hoping to get an answer for this as I am sure this code could help others who ve been trying to get some sort of resume audio function that isn t bulky or confusing to use. :) I ve been trying to find a solution for quite awhile and never have been this close. Thank you for reading. If you d like the whole PHP function then I ll show that too but there s really nothing to see except two debug buttons (Reset and Alert cookie) and the audio tag with the id music_$song .

<强度 > 编辑 : 仅要明确, 在代码中, 在双引号之前有一些逃跑, 因为正返回 pHP 函数中的 Javascript 。

编辑 2: 现在用粗体粗体显示这个编辑, 因为有人错过了它。 此外, 我添加了 PHP 部分 。

Last edit: I have now seemed to figure something out that got me closer to what I wish to achieve. I changed the above code to the following and it works flawless for me.

function playmusic($song, $resume=false, $loop=true)
 {
  global $baseurl, $loggeduser;

 if ($resume == true)
  {
   $resume = "
    <!--
    <button onclick="resetplaytime();" type="button">Reset</button>
    <button onclick="alertplaytime();" type="button">Alert Time</button>
    <button onclick="settimecookie();" type="button">Start Cookie tracking</button>
    -->

    <script type="text/javascript">
     function getcookie(c_name)
      {
       var i,x,y,ARRcookies=document.cookie.split(";");
      for (i=0;i<ARRcookies.length;i++)
       {
        x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
        y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
        x=x.replace(/^s+|s+$/g,"");
       if (x==c_name)
        {
         return unescape(y);
        }
       }
      }

     function settimecookie()
      {
       var curmusic_$song = document.getElementById("music_$song");
       var playtime = curmusic_$song.currentTime;
      if (playtime != null && playtime != "")
       {
        document.cookie = "musicplaytime_$song=" + playtime;
       }

       setTimeout("settimecookie()", 50);
      }

     function resumeplaytime()
      {
       var curmusic_$song = document.getElementById("music_$song");
       var musictime = getcookie("musicplaytime_$song");
      if (musictime != null && musictime != "")
       {
        curmusic_$song.currentTime = musictime; 
       }
       curmusic_$song.play(); 

       settimecookie();
      }

      window.onload=resumeplaytime;

     function alertplaytime()
      {
       var musictime = getcookie("musicplaytime_$song");
       alert(musictime);
      }

     function resetplaytime()
      {
       var curmusic_$song = document.getElementById("music_$song");
       curmusic_$song.currentTime=0;
      }

    </script>";
  }
 else
  {
   $autoplay = "autoplay="true"";
  }

 if ($loop == true)
  {
   $songloop = " loop="true"";
  }

 if ($loggeduser[ mutemusic ] == 0)
  {
   return "
    </table>
    $resume
    <audio id="music_$song" $autoplay$songloop preload="true">
      <source src="$baseurl/boardfiles/effects/$song.ogg" type="audio/ogg" />
      <source src="$baseurl/boardfiles/effects/$song.mp3" type="audio/mp3" />
    </audio>
    <table class="brdr" cellpadding="0">";
  }
 }

It seems to work perfectly now. I changed a few things and now works as I want it to. Thanks for the help! :)
