In my cordova app I am opening(using InAppBrowser plugin) a webpage in inappbrowser by the following code.

var ref = cordova.InAppBrowser.open('', '_blank', 'location=yes');
ref.close();

Now I want to check if the InAppBrowser is closed(not a particular URL I want to check the browser itself open or closed) in js like ref.isClosed(). But InAppBrowser doesn't facilitate such function. Is there any way to find it?

You could just create a simple wrapper to keep track of whether it's open or closed, e.g.:

var iab_controller = (function(){
    var ref, isOpen = false;

    return {
        open: function(url){
            ref = cordova.InAppBrowser.open(url, '_blank', 'location=yes');
            isOpen = true;
            return ref;
        },
        close: function(){
            if(isOpen){
                ref.close();
                ref = null;
                isOpen = false;
            }
        },
        isOpen: function(){
            return isOpen;
        },
        isClosed: function(){
            return !isOpen;
        }
    };

})();

console.log("isOpen: " + iab_controller.isOpen())
console.log("isClosed: " + iab_controller.isClosed())

iab_controller.open('http://apache');

console.log("isOpen: " + iab_controller.isOpen())
console.log("isClosed: " + iab_controller.isClosed())

iab_controller.close();

console.log("isOpen: " + iab_controller.isOpen())
console.log("isClosed: " + iab_controller.isClosed())

var browserRef = cordova.InAppBrowser.open('http://apache', '_blank', 'location=yes');
var isOpen = true;

browserRef.addEventListener('exit', function(event) {
  console.log('exit: event fires when the InAppBrowser window is closed.');
  isOpen = false;
});

Add a listener for an exit event from the InAppBrowser. This will allow you to perform logic or set a variable to manage state.
