我正在使用Cordova 6.2.0并希望覆盖Android上的后退按钮。我找到了以下解决方案，但这对我不起作用（我猜这是因为Cordova版本）：link。 我使用以下代码覆盖后退按钮：
document.addEventListener("deviceready",ondeviceready, false);
function ondeviceready()
{
document.addEventListener("backbutton", onBackKey, false);
}
function onBackKey()
{
//Do something
}
问题是后门按钮只在第一页上“做了些什么”。这是我的index.html页面：
<html>
<head>
<meta charset="utf-8"/>
<meta name="format-detection" content="telephone=no" />
<meta name="msapplication-tap-highlight" content="no" />

请尝试以下代码。它适合我
在HTML中：
<body onload="onLoad()">
：
function onLoad(){
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady() {
document.addEventListener("backbutton", onBackKeyDown, false);
}
function onBackKeyDown() {
}

我找到了解决问题的方法。我使用window.open("page.html","_self")函数浏览我的页面。 This是问题，因为我在我的应用程序中创建了一个新的浏览器实例。相反，它更聪明地使用以下功能：
window.location="page.html"
现在onBackKey()函数正在每个页面触发。
