Not working--what more is needed?

[szalapski]

Hmm, it's not working for me. I added it in my client's Paogram.cs, and inject, just as the example. After I implement and attach a function to beforeUnload.BeforeUnloadHandler, shouldn't (in my browser console) window.beforeunload have a value? It does not for me.

Hey,
yes, window.onbeforeunload, is usually used, but here event listener version is being used. When called from Blazor the event listener should be added, bound to C# handler via interop:
https://github.com/peterblazejewicz/blazor-beforeunload/blob/master/src/BlazorBeforeUnload/wwwroot/BeforeUnload.js
So technically, there should be window.BeforeUnloadInterop in your console if everything is OK (sorry, I haven't tested this wiht recent BL versions)

Hi, you need to add this to your wwwroot/index.html:

    <script src="_content/BlazorBeforeUnload/BeforeUnload.js"></script>
