最后使用JQuery播放声音文件

;(function($){
    $(function() { // $(document).ready(); 文档准备好后运行
         
        var banner_audio= new Audio(),        // 创建Audio.
             webm = isSupportWebM();    // 检查是否支持webm格式
        banner_audio.src = 'media/banner_sound.mp3';
        /*if(webm) {   //支持webm格式
            banner_audio.src = 'media/banner_sound.webm';
        } else {    // 不支持webm格式
            banner_audio.src = 'media/banner_sound.mp3';
        };*/
        $('.banner')
            .bind('mouseover focusin', function() { // 当发生MouseOver，FocusIn事件时调用处理函数
                banner_audio.load(); // 加载audio
                banner_audio.play(); // 播放audio
            })
            .bind('mouseout focusout', function() { // 当发生MouseOut，FocusOut事件时调用处理函数
                banner_audio.pause();             // 暂停audio
                banner_audio.currentTime = 0;    // 初始化audio播放位置
            });
         
    });
})(window.jQuery);
 
// 检测是否webm格式的函数
function isSupportWebM() {
    var tester = document.createElement('audio');
    return !!tester.canPlayType('audio/webm');
};
