Onsen uI:Controll android backbutton routes:

问题:

I am developing an android application in cordova using Onsenui,in which i want to navigate to previous page when device backbutton is clicked I am using answer from this question to solve the issue

Here is my code

document.addEventListener("backbutton",onBackButtonPressed, false);
    function onBackButtonPressed(){
            alert('backbutton');
            var element = document.querySelector( ".navigator-container");
            var scope = angular.element( element ).scope();
            scope.popPage();
    }

I will get the following error

"Uncaught TypeError: Cannot read property 'popPage' of undefined"

Probably .navigator-container has been deprecated, that's why I suggest you to get the navigator by using ons-navigator as argument for document.querySelector().

Here is the fixed code:

document.addEventListener("backbutton",onBackButtonPressed, false);
    function onBackButtonPressed(){
            alert('backbutton');
            var element = document.querySelector("ons-navigator");
            element.popPage();
}

EDIT

Supposing that you are using an older version of Onsen UI, like 1.3.4, and supposing that your navigator has a var='myNavigator' attribute, you can use the following code:

document.addEventListener("backbutton",onBackButtonPressed, false);
    function onBackButtonPressed(){
            alert('backbutton');
            var element = document.querySelector("ons-navigator");
            var scope = angular.element(element).scope();
            scope.myNavigator.popPage();
}
