推荐答案

简短的回答不是，您不能仅使用jQuery Mobile来做到这一点.

Short answer is no, you can't do that with a jQuery Mobile only.

现在，我假设您正在创建一个移动应用程序，通过移动应用程序，我的意思是混合android/iPhone应用程序，而不是您的Web应用程序的移动版本.如果我是正确的话，您可能会使用Phonegap/Cordova框架包装程序，该包装程序将作为HTML/CSS/JS和natuve应用程序之间的包装程序.

Now I would assume you are creating a mobile application, and by mobile application I mean hybrid android/iPhone app and not a mobile version of your web app. If I am correct you will probably use a Phonegap/Cordova framework wrapper which will server as a wrapper between your HTML/CSS/JS and a natuve app.

jQuery Mobile和Phonegap是标准组合，您可以找到很多有关教程的方法.

jQuery Mobile and Phonegap is a standard mix, you can find a lot of how to tutorials.

但是回到您的问题，这是如何使用Phonegap将音量增大和音量减小事件绑定到jQuery移动代码:

But back to your question, here's how you can bind volume up and volume down event using Phonegap to jQuery mobile code:

document.addEventListener("volumedownbutton", onVolumeDownKeyDown, false);

function onVolumeDownKeyDown() {
    // Handle the volume down button
}

和:

document.addEventListener("volumeupbutton", onVolumeUpKeyDown, false);

function onVolumeUpKeyDown() {
    // Handle the volume up button
}

也请看一下我的另一篇短篇文章，如何使用jQuery mobile处理电话间隔事件:
