我用 backKeyDown 和它的作品对我来说：

 函数onDeviceReady（）{
        document.addEventListener（后退按钮，backKeyDown，真正的）;
        的console.log（PhoneGap的是准备好了）;
    }    功能backKeyDown（）{
        navigator.app.exitApp（）; //要退出应用程序！
    }
 

确保 PhoneGap的准备！

更新：：您可以将处理程序空的禁用

Could someone please tell me how to disable Android's back button (That is the back-button found on all Android phones).

I am using Jquery mobile with PhoneGap. I find this online in the Cordova documentation, but this does not work for me. Back button event is not even registering.

function onLoad() {
    console.log("**** INSIDE ONLOAD FUNCTION *****");
    document.addEventListener("backbutton", onBackKeyDown, false);   
}

// Handle the back button
function onBackKeyDown() {

    // Pressing the back button does not print this message.
    console.log("**************** INSIDE BACK BUTTON *************");
}

I used backKeyDown and it works for me :

function onDeviceReady() {
        document.addEventListener("backbutton", backKeyDown, true);
        console.log("PhoneGap is ready");
    }

    function backKeyDown() {
        navigator.app.exitApp(); // To exit the app!
    }

make sure that PhoneGap is ready!

Update: You can leave the handler empty to disable it
