Yes. A WebView can do almost everything a web browser can do in terms of rendering HTML and executing JavaScript code.
So there’s nothing stopping you having an <input> element that accepts user-entered text (e.g. a URL), and a <button> element that, when clicked calls a JavaScript function that loads the page at the given URL into the current WebView.
Cool. Thanks for the reply. Do you know how to make this? I'd pay ya. (I can only "code" using "non-code" languages. CSS & Html are the extent of my knowledge.)
