Unable to use InApp browser options

Hi i am a newbie to the ionic frame i am learning ionic by my self and while practising i got a problem with the InApp Browser
Below is my code
Index.html code :

<ion-header-bar class="bar-stable">

    <h1 class="title">InAppBrowser</h1>
</ion-header-bar>
<ion-content ng-controller="ExampleController" padding="true">
    <button class="button button-full button-assertive" ng-click="openInExternalBrowser()">
        Open In External Browser
    </button>
    <button class="button button-full button-assertive" ng-click="openInAppBrowser()">
        Open In App Browser
    </button>
     <button class="button button-full button-assertive" ng-click="openCordovaWebView()">
        Open In Cordova Webview
    </button>
    
</ion-content> 

Code in App.js :

angular.module(‘starter’, [‘ionic’])

.controller(“ExampleController”, function ($scope) {

$scope.openInExternalBrowser = function()
{
// Open in external browser
window.open(‘http://192.158.0.35/new/’, ‘_system’);
};

$scope.openInAppBrowser = function()
{

// Open in app browser
window.open(‘http://192.158.0.35/new’, ‘_blank’, ‘’);
};

$scope.openCordovaWebView = function()
{
// Open cordova webview if the url is in the whitelist otherwise opens in app browser
window.open(‘http://192.158.0.35/new’, ‘_self’, ‘location=no’);
};

});

Above is my code here are the problems i am facing

  1. Unable to add Zoom controls already tried

window.open(‘http://192.158.0.35/new’, ‘_self’, ‘location=no,zoom=yes’);

  1. The link im trying to call is site based on .net and ajax based site is opening but in that **File Opening Dialouge ** not opening

  2. How to insert header and footer for InApp Browser along with the and i want add exit button in the footer

Please Post some examples or Please modify above and let me Know

Inapp browser will not allow you to insert or additional scripts or html. It calls a webpage and in that you do whatever you want.
