The error message "TypeError: Unable to access property 'ready' of undefined in IONIC2" is displayed

I am currently working on integrating the InAppBrowser in IONIC2.

Successfully installed Browser Plugin 

ionic plugin add cordova-plugin-inappbrowser

Here is my .TS code for opening the browser

browser(url:string)
{
  this.platform.ready().then(() => {
           open(url, "_blank", "location=true");
        });

}

And here is the corresponding HTML code 

 <button (click)="browser('https://www.google.com')" >Open Browser</button>

However, when trying to execute it

I encountered the following error message:

ORIGINAL EXCEPTION: TypeError: Cannot read property 'ready' of undefined

Answer №1

Have you set up the platform variable in the constructor of your .ts file?

Be sure to import it first, for example:

import {Platform, ...} from 'ionic-angular';

Then, within the constructor:

constructor(private platform: Platform, ...) {
    ....
}

Answer №2

I had a similar experience with this issue. Following the tutorial I was following, I added the provided code snippet to the class declaration:

    static get dependencies() {
        return [[Service]];
    }

However, once I removed this section of code, the error was resolved and the feature functioned correctly.

Although my reply might be delayed, I hope it can assist others encountering the same problem in the future.

Answer №3

In order to ensure the variables functioned correctly, I made sure to designate them as private within the constructor.

  openBrowser(private url:string, private platform: Platform)
  {
    this.platform.ready().then(() => {
       window.open(url, "_blank", "location=true");
    });
