            I modified the React part after seeing the comments of the ToolmakerSteve.

            At first I thought that the function could not be found because the function was renamed during a production build of react, but I found that it works regardless (It was just my misunderstanding that the method executed in JavaScript and the method executed in C# had the same name.)

            Also I didn't know eval() how to do Invoke C# Code in jsx I was wondering if I could use a method like

            QUESTION

            Is there a way to create bi-directional communication between a shell app and a webview in .NET 6 MAUI?
            Asked 2021-Aug-21 at 22:28

            Recently I've had the assignment to create a bi-directional interop bridge between a shell app and a webpage in .NET MAUI. Not finding any way to solve this I had the idea of creating it in Xamarin.Forms first seeing as MAUI is a continuation on it.

            After having created this app, I've tried to convert it over to MAUI using Microsoft's instructions on the dotnet/maui github wiki.

            The main problem i'm encountering right now is that I've been using extensions on Android's WebViewRenderer, WebViewClient and Java.Lang.Object to be able to send and receive javascript to and from the WebView.

            ANSWER

            Answered 2021-Aug-21 at 22:28

            MAUI's default WebView has the Eval and EvaluateJavaScriptAsync functions to call JavaScript code from C#:

            • Eval just executes the script string you pass in a fire-and-forget way.
            • EvaluateJavaScriptAsync needs to be awaited but also returns a string with a stringified result of the data that the script returned.

            If you want to use callback/bridge methods to automatically receive data from the JavaScript side without any input from the C# side of the app, you will have to extend the default per-platform renderers to add that functionality. The good news is that there is an official tutorial on how to do it for Xamarin Forms at Customizing a WebView which is almost straightforward to port to .NET MAUI - you only have to change how renderers are registered.

            It turns out my JSBridge was being destroyed by the garbage collector and because of VLCJ it was faster.

            If you create a JSBridge variable inside the class, then the garbage collector will not destroy it and everything will work.

            How to access foreground service from WebView Javascript Bridge
            Asked 2020-Mar-29 at 04:12

            I will try and explain everything to the best of my ability, but I am new to using Xamarin so please bear with me while I try to give you an understanding of my situation.

            I am using Xamarin Forms to build an Android application, I already have a desktop application that uses Electron so I have lots of pre-built user interface in HTML which I am using in a HybridWebView for the interface and JSBridge to call the C# code.

            My application will only be installed on a clients network of devices, and we have set up a foreground service, that has a service notification to keep the background jobs running; this is all working as intended.

            Calling C# code from the HTML interface is easy enough using the JSBridge / HybridWebView, however, I am unable to find a way that allows my C# functions inside the JSBridge class to talk to my foreground service which has already been started by the MainActivity, this service runs background jobs that return data that my UI will need access to.

            My Service is being started in the MainActivity OnCreate like so:

            As suggested by SushiHangover, using a bound service is the way to go.

            The documentation isn't very helpful and while it says a bound service calls OnBind() to start, it also mentions that it can also call OnStartCommand. However, the documentation doesn't mention that to have OnStartCommand fire you need to call StartService as well as BindService.

            For Problem (1, 2)

            HTTPS link worked fine for me, maybe the page is too slow to load?

            According to Microsoft (source), only ScriptNotify is supported in WebView:

            Can I inject native objects into my WebViewControl content?

            No. Neither the WebBrower (Internet Explorer) ObjectForScripting property nor the WebView (UWP) AddWebAllowedObject method are supported in WebViewControl. As a workaround, you can use window.external.notify/ ScriptNotify and JavaScript execution to communicate between the layers, for example: https://github.com/rjmurillo/WebView_AddAllowedWebObjectWorkaround

            But the above suggested workaround solution seems to work differently to your expectation, so I just implement my own solution to emulate the JSBridge convention you have expected.

            My custom solution is not battle-tested, it might break in some edge cases but it seems to work fine in few simple tests.

            What's supported:

            • Multiple bridge objects
            • JS to C# method call
            • JS to C# get/set property

            SyncFusion SfRichTextEditor doesn't return edited text using Prism, Xamarin.Forms on Android
            Asked 2020-Jan-08 at 11:16

            I am using Xamarin.Forms with Prism and the Syncfusion RichTextEditor component on an Android device. The issue I am having is that I can't seem to retrieve the edited text back in the view model. I have used a binding to the Text property, which is always null. I have tried to add an event handler for "TextChanged" event in the code behind - this event is never fired. I have attempted to call RichTextEditor.GetHtmlString() in the code behind too - which returns null.

            The editor displays correctly in the app and all editing functionality(bold, italic etc.) seem to work just fine, however a warning in the output log shows:

            [INFO:CONSOLE(1)] "Uncaught TypeError: jsBridge.invokeAction is not a function", source: (1)12-19 11:10:32.963 I/chromium(13310): [INFO:CONSOLE(1)] "Uncaught TypeError: jsBridge.invokeAction is not a function", source: (1)

            Xamarin.Forms - 4.4.0.991265

            Syncfusion.Xamarin.SfRichTextEditor - 17.4.0.39

            Edit: Syncfusion support have provided an example where the modified text is correctly updated in the view model. The only visible difference is that it is using Unity not DryIoc. I have created a replica sample project using DryIoc and the updated text is still correctly being populated in the view model... must be something to do with the project setup!!

            After removing all nugets and unrelated code from the solution my code still returned null when updating the text.

            Looking into the Android project setup vs the newly created sample solution I found that the "Dex Compiler" was set to D8 in my project but DX by default in both test solutions, changing that to DX fixed the issue... Text and HtmlText are now correctly being bound to the viewmodel and I can extract their values!
