Javascript 通过扩展chrome控制播放器按钮

我创建了扩展： HTML代码较低：

<input id="play1" type="image" src="images/121.png"  type="button"  alt="Воспроизвести"/>
<input id="pause1" type="image" src="images/120.png"  type="button" alt="Пауза"/>
<input id="next1" type="image" src="images/122.png"   type="button" alt="След.трек"/>

播放器按钮的控制代码：

<input id="play1" type="image" src="images/121.png"  type="button"  alt="Воспроизвести"/>
<input id="pause1" type="image" src="images/120.png"  type="button" alt="Пауза"/>
<input id="next1" type="image" src="images/122.png"   type="button" alt="След.трек"/>

<div id="ac_controls" class="fl_l">
    <div id="ac_play" class="fl_l"></div>
    <div class="next_prev fl_l">
      <div id="ac_prev" class="ctrl_wrap">
        <div class="prev ctrl"></div>
      </div>
      <div id="ac_next" class="ctrl_wrap">
        <div class="next ctrl"></div>
      </div>
    </div>
  </div>

然后您需要使用

窗口。onload

。您的脚本将如下所示：

<input id="play1" type="image" src="images/121.png"  type="button"  alt="Воспроизвести"/>
<input id="pause1" type="image" src="images/120.png"  type="button" alt="Пауза"/>
<input id="next1" type="image" src="images/122.png"   type="button" alt="След.трек"/>

 <script type="text/javascript">

window.onload = function() {
    document.getElementById("play1").onclick = function() {
        alert("hello"); //for testing
    }
}
 </script>

您是否在html文件中引用jQuery？例如：

@pavel bogrInstead of aleret（'）；我需要按下选项卡中的按钮：https:/test.com/audio/，按钮播放器的代码上述按钮播放器的代码
