我正在使用 jquery mobile 更新页面中的 div 以播放一些动画。

动画还通过使用document.createElement('audio');

我的问题是，当我将页面更新为另一个动画时，旧声音继续播放。

抱歉，这是我的第一个问题，如果我的措辞不正确，我深表歉意。

这是我的代码..

这是要加载到#animation div中的动画代码

这是主页代码。当您单击下一步按钮时，它会从数组中获取要加载到#animation 的动画页面的文件名。

<div id="nav" data-role="content" style="width: 600px; margin: 0 auto; text-align: center; position: relative; top:450px">
    <a href="#animation" data-role="button" data-inline="true" id ="back">Back</a>
    <a href="#animation" data-role="button" data-inline="true" data-theme="b" id="next">Next</a>
    <script>
        var count=0;
        var link_array = ['baby', 'bed', 'book', 'cat', 'chair', 'daddy', 'dog', 'mummy', 'shoe', 'teddy'];
        $("#next").click(function(e) {
            if(count!==9)
            { 
                $('audio').stop();
                count+=1;
            }
            $('#animation1wl').load('../Animations/' + link_array[count] + '.html');
            $('#animation1wl').trigger('create');
        }); 
        $("#back").click(function(e) {
            if(count !==0)
            {
                count-=1;
            }
            $('#animation1wl').load('../Animations/' + link_array[count] + '.html');
            $('#animation1wl').trigger('create');
        }); 
    </script>
</div>

<div id="animation" data-role="content" style="width: 600px; margin: 0 auto; text-align: left">Problem Loading Resource LNW</div>

当我单击前进或后退按钮时，我希望将上一个动画中的音频加载到#animation 中以停止播放..

这是在#animation 中呈现的代码

你可以这样做：

$('audio').each(function(){
    this.pause(); // Stop playing
    this.currentTime = 0; // Reset time
});

Ihad to rewrite the code but, I got this working in the end by loading the animation in its entirety when you click on the next button rather than just updating a single div.

It's a workaround but at least its working now.

Thanks to Omar who helped a lot with this problem.
