Question

我的Javascript / jQuery函数只运行一次，只有函数的底部部分正常工作。我可以翻转订单，然后另一件就行了。我缺少什么（使用Buzz音频API播放和暂停方法）？

var $playFromPlayerBar = $('.main-controls .play-pause');

var togglePlayFromPlayerBar = function(){
    if (currentSoundFile.pause() && $playFromPlayerBar.click){
        var $songNumberCell = getSongNumberCell(currentlyPlayingSongNumber);
        $songNumberCell.html(pauseButtonTemplate);
        $playFromPlayerBar.html(playerBarPauseButton);
        currentSoundFile.play();
    } 

    if (currentSoundFile.play() && $playFromPlayerBar.click){
        var $songNumberCell = getSongNumberCell(currentlyPlayingSongNumber);
        $songNumberCell.html(playButtonTemplate);
        $playFromPlayerBar.html(playerBarPlayButton);
        currentSoundFile.pause();
    }  

};

//load album when window loads
$(document).ready(function() {
    $playFromPlayerBar.click(togglePlayFromPlayerBar);
});

Answer 1

这里的绑定可能有问题，尝试这样的事情：

$playFromPlayerBar.click

此外，您需要调用点击功能，并在条件表达式中执行此操作：

$playFromPlayerBar.click()

你应该这样做：

fsx

啊哈!!我想通了。

var togglePlayFromPlayerBar = function(){
    if ($playFromPlayerBar.click){
        var $songNumberCell =           getSongNumberCell(currentlyPlayingSongNumber);

        if (currentSoundFile.isPaused()){
            $songNumberCell.html(pauseButtonTemplate);
            $playFromPlayerBar.html(playerBarPauseButton);
        } else {
            $songNumberCell.html(playButtonTemplate);
            $playFromPlayerBar.html(playerBarPlayButton);
        }

        currentSoundFile.togglePlay();
    }
};


//load album when window loads
$(document).ready(function() {
    $playFromPlayerBar.click(togglePlayFromPlayerBar);
});

Java Script函数只运行一次
