WebBrowser is using Internet Explorer which has been retired by Microsoft. Try with TEdgeBrowser instead. Look at Delphi documentation https://docwiki.embarcadero.com/RADStudio/Sydney/en/Using_TEdgeBrowser_Component_and_Changes_to_the_TWebBrowser_Component

[Lajos Juhász 238]

If you really want to use TWebBrowser you must  set FEATURE_BROWSER_EMULATION before using the component (Windows is going to  remove it from the registry constantly). Of course this is only a short term solution as IE is dead.

To be honest, I have never heard of that, let alone experienced it myself.

 

It is still working fine, at least for the parts where have not migrated to the (fantastic!) EdgeBrowser yet.

For me it's happening for about a year maybe a bit longer, before that I used  the registry entry for years without a problem.

Add

WebBrowser1.Silent := True;

to suppress script errors.

To give a

WebBrowser1.Silent := True;

to suppress script errors is not a solution!!!!!

 

I have the same problem with the Delphi 11.3 sample called "WebBrowser" running on Win11. It is impossible to load a website (even bing.com!!!) without these script errors.

 

And "do not display these errors" does not prevent malfunctions of the website!!!!

 

So I'm reactivating the question, does anyone know why the Webbrowser sample is unable to play javascripts and is there a solution? Since these are samples provided by Embarcadero itself, we shouldn't even have to ask this question 😞

If anyone wonders why you insist on using delphi to display a website, I'd like to point out that the latest versions of Chrome and Edge (and maybe others) have changed their popup management, making many sites unusable without any prior announcement that I'm aware of!

Wait ... what? Didn't Bill Gates testify before Congress that IE is an "integral part of the OS" and that "Windows would not work without it?"

This solution has a note "Asked 8 years, 9 months ago"... 8 years ago, what version of Windows was in use? Do we have the same ie sources in a Windows OS 8 years ago and in Win11?

Yes, we do. Nothing has changed.

You still have two options:

1. Set IE emulation to something newer than 2006
2. Use an alternative from this decade (like the chromium-based WebView2 engine)
