javascript - Changing div background on audio play -


i'm trying setup clicking on div plays audio (this working), , changes background image of div (not working). audio pauses if button clicked again during playing, , background image needs keep up, it's similar pause/play visual.

what've got wrong here isn't working?

    <!doctype html>     <html>     <head>     <meta charset=utf-8/>     <title>janice's button</title>     <style type="text/css">         * {             margin: 0;             padding: 0;         }          #button {             position: absolute;             height: 100%;             width: 100%;             overflow: hidden;             background-size: contain;         }          #clicker {             z-index: 1000;             position: absolute;             left: 30%;             top: 10%;             width: 40%;             border: 1px solid red;             border-radius: 100%;         }          .unpressed {             background:  url("buttonimgunpressed.jpg") no-repeat center top;         }          .pressed {             background:  url("buttonimgpressed.jpg") no-repeat center top;         }           #clicker:before{             content: "";             display: block;             padding-top: 100%;  /* initial ratio of 1:1*/         }          .new     </style> </head> <body>     <div id="button" class="unpressed">     </div>     <div id="clicker" onclick="play()"></div>     <audio id="audio" src="rocky.mp3"></audio>     <script>         function play() {             var audio = document.getelementbyid('audio');             var button = document.getelementbyid('button')             if (audio.paused) {                 audio.play();                 $('#button').removeclass('unpressed');                 $('#button').addclass('pressed');             }else{                 audio.pause();                 audio.currenttime = 0                 $('#button').removeclass('pressed');                 $('#button').addclass('unpressed');             }         }     </script> </body>
