Question

我正在尝试使用触发不同音频剪辑的按钮制作数字MPC。

我点击了一次按钮即可运行并播放音频，但是，我正在尝试再次点击时暂停音频。

我已将所有代码输入到此帖子中，任何人都想运行它，但我的问题是在带有“mousedown”功能的Javascript文件中。

如果有人能提供见解，我会很感激。

我只想使用布尔标志来表示播放状态。

var playing = false;

$('.pad-1').mousedown(function() {
    if(!playing) {
        play();
    } else {
        pause();
    }
});

function play() {
   padOne.load();
   padOne.play();
   playing = true;
}

function pause() {
   padOne.pause();
   playing = false;
}
