WebView Issues: Modals and JavaScript Buttons Not Working

[characharm]

There are a couple of issues with the WebView opened by the plugin:

1. Modal dialogs (like alert or confirm) are not appearing.
2. JavaScript buttons on the page (e.g., a "Copy" button or other interactive JS-driven elements) are not functioning.

Could you please check the WebView settings in the plugin? It seems like additional permissions might be needed for these elements to work.

Thanks!

alert and confirm do not work in VS Code WebView for security reasons and for now I think it's ok. However, Copy and Regenerate buttons work in my tests.
Could you give some additional information how to reproduce the problem (environment, steps)?

VS Code Version: 1.100.0 (user setup)

V8: 13.2.152.41-electron.0
OS: Windows_NT x64 10.0.26100
Plugin version: v0.0.10
Steps: I open the "Chat with AI" view using the CTRL+; shortcut. There's nothing special about the setup otherwise.

Regenerate button works fine. Issue I'm seeing is with the Copy button. When I click the Copy button next to a message, it displays a "Copied!" confirmation message, but nothing is actually placed into the clipboard
Additionally, I'm unable to delete conversations. Clicking the Delete button for a chat has no effect; the conversation remains.

Thanks. For Copy button I see that there is a delay on pasting (could be long if the conversation is long), but it works on my side. For the Delete button for a chat - yes, it doesn't work. It uses Confirm popup, which is not supported by WebView. Will think what can we do about it.

[characharm]

Can the plugin control the WebView's IndexedDB? Maybe it could clear the relevant conversation data from IndexedDB when the plugin starts
Alternatively, maybe a button could be added to the plugin's settings specifically for clearing the conversation history?

@characharm The modal popups should work now in webui (the fix is in the latest llama.cpp, so no new llama.vscode version). Now it uses custom modals, which is acceptable for WebView. Could you check if it resolves the problems you mentioned?

@igardev
Yes, I've seen your PR for the llama-server web UI. Chat deletion is working. But unfortunately, the 'Copy' button isn't working correctly. Please see the video:
