Close pop up on back button

Question

I want to close pop up on click of back button for mobile. I implemented this using onhashchange:

window.onhashchange = function (event) {

};

Answer 1

I'll did it like this :

// 2.0 and above
@Override
public void onBackPressed(evt) {
    evt.preventDefault();
    closeTab();
}

// Before 2.0
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        evt.preventDefault();
        closeTab();
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

--> These are handlers btw, need addEventListener =)

I've done it by memory, i'll check it later when i find it in my 'code mess' folder
