What is the best way to include JavaScript in a web view within an Ionic Android application?

I'm in the process of incorporating a header bar into the web view for my app. Utilizing the cordova inAppBrowser plugin to achieve this, I tested using the following code:

var win = window.open( URL, "_blank", 'location=yes' );
win.addEventListener( "loadstop", function() {
    win.executeScript({ code: "alert( 'hello' );" });
});

The URL is successfully opened, however, no alert appears in the web view.

UPDATE:

Upon further investigation, it became evident that the method executeScript() is not defined. This results in an error message, "

TypeError: undefined is not a function
". Similar issues occur with win.show() and win.addEventListener(). Strangely, only open() and close() are functioning as expected. Could there be an issue with the installation?

Answer №1

Give this a shot,

let element=document.createElement('script');
element.src=alert( 'hi' );
element.type='text/javascript';
