The following editor will bring you an implementation method of using phonegap to play audio. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

The examples are as follows:

<!DOCTYPE html>

    <head> 
        <meta charset="UTF-8"> 
        <title>Compass Example</title>

        <script type="text/javascript" charset="UTF-8"> 
            document.addEventListener("deviceready", onDeviceReady, false); 
  
            function onDeviceReady() { 
            } 
              
            var my_media=null; 
            var mediaTimer=null; 
              
            function playAudio(src){ 
                my_media=new Media(src,onSuccess,onError); 
                my_media.play(); 
                  
                if(mediaTimer==null){ 
                    mediaTimer=setInterval(function(){ 
                        my_media.getCurrentPosition( 
                            //成功回调 
                            function(position){ 
                            if(position>-1){ 
                                setAudioPosition((position/1000)+"sec"); 
                            } 
                        }, 
                        //错误回调 
                        function (e){ 
                            console.log("Error getting pos="+e); 
                            setAudioPosition("Error: "+e); 
                        } 
                        ); 
                    },1000); 
                } 
            } 
              
            function pauseAudio(){ 
                if(my_media){ 
                    my_media.pause(); 
                } 
            } 
              
            function stopAudio(){ 
                if(my_media){ 
                    my_media.stopAudio(); 
                } 
                clearInterval(mediaTimer); 
                mediaTimer=null; 
            } 
              
            function onSuccess(){ 
                console.log("playAudio():Audio Success"); 
            } 
              
            function setAudioPosition(position){ 
                document.getElementById(&#39;audio_position&#39;).innerHTML=position; 
            } 
  
            //错误的回调  
            function onError(error) { 
                alert(&#39;code:&#39;+error.code+&#39;\n&#39;+&#39;message:&#39;+error.message+&#39;\n&#39;);
