Phonegap - navigator.app.backHistory() not working on HTML back button

Question

In my app i am using phonegap 2.6.For back button, I am using the following function

document.addEventListener(\"backbutton\", onBackKeyDown, false);

functi         


        

Answer 1

I have tried 3 separate things when I faced the same situation:

• window.history.back()

• navigator.app.backHistory();

• History.go(-1);

Individually, none of these solve the problem. I put all 3 things together and much to my surprise it worked. I really don't know what is behind it.

Then I decreased to two functions and removed:

• window.history.back()

Now I am using this function and it is working fine.

//Works Fine
function onBackKeyDown() {
    history.go(-1);
    navigator.app.backHistory();
}

Answer 2

it depends where you are: on my windowsphone 8.1 lumia 925, it works history.go(-1);, while navigator.app.backHistory(); causes an exception before crashing.

On my Android (I believe the majority), navigator.app.backHistory(); works properly.

Answer 3

If you use the attribute data-rel="back" on an anchor, any clicks on that anchor will mimic the back button, going back one history entry and ignoring the anchor's default href.

Answer 4

Solved! Stop getting "TypeError: navigator.app is undefined"

A function I created that will first check what device you're on and then apply the relevant script:

function onBackKeyDown() {
    var userAgent = navigator.userAgent || navigator.vendor || window.opera;
    if (userAgent.match(/iPad/i) || userAgent.match(/iPhone/i) || userAgent.match(/iPod/i)) {
        // IOS DEVICE
        history.go(-1);
    } else if (userAgent.match(/Android/i)) {
        // ANDROID DEVICE
        navigator.app.backHistory();
    } else {
        // EVERY OTHER DEVICE
        history.go(-1);
    }
}

Call function by adding this to your back link/button:

onclick="onBackKeyDown()"
