Javascript

We called the javascript script when clicking the switch image button, playPause( )function. The function determines the audio playback state. If it has stopped (paused), call .play() to continue playing. If it is in the playing state, immediately pause playback.pause(). When the two states switch, the button image is updated in time. Please see Code:

JavaScript

function playPause() { var music = document.getElementById('music2'); var music_btn = document.getElementById('music_btn2'); if (music.paused){ music.play(); music_btn.src = 'play.gif'; } else{ music.pause(); music_btn.src = 'pause.gif'; } } 如果使用jQuery代码可以这样写：
