Reviewer's GuideAdds optional Blazor component callbacks for HikVision login/logout and start/stop real play events, wires them into the existing methods, slightly adjusts the stop-real-play logic, and removes a debug log from the JS plugin.

Hey there - I've reviewed your changes - here's some feedback:
- In
Logout,TriggerLogoutedis invoked even whenIsLoginedis false, which may surprise consumers expecting the callback only on actual logout; consider guarding the callback with the sameIsLoginedcheck or documenting the semantics explicitly. - The new
StopRealPlayimplementation no longer considers the success/failure of the underlying JS call and unconditionally clearsIsRealPlayingand fires the callback; if the stop operation can fail, you may want to retain a success flag or error handling to keep state and callbacks aligned with the actual player state.

## Overall Comments
- In `Logout`, `TriggerLogouted` is invoked even when `IsLogined` is false, which may surprise consumers expecting the callback only on actual logout; consider guarding the callback with the same `IsLogined` check or documenting the semantics explicitly.
- The new `StopRealPlay` implementation no longer considers the success/failure of the underlying JS call and unconditionally clears `IsRealPlaying` and fires the callback; if the stop operation can fail, you may want to retain a success flag or error handling to keep state and callbacks aligned with the actual player state.

**issue (bug_risk):** Consider preserving stop result handling to avoid inconsistent IsRealPlaying state.
Previously we only set `IsRealPlaying = false` when `stopRealPlay` reported success. Now `InvokeVoidAsync` is used and we always set `IsRealPlaying` to false and trigger `OnStopRealPlayedAsync`, even if the underlying JS `I_Stop` fails. This can leave C# thinking the stream is stopped while the plugin is still playing. If the JS call can fail, please preserve a success/failure result or expose an error path so C# state and callbacks stay aligned with the actual player state.

Pull request overview
This PR adds callback functionality to the HikVision web plugin component, enabling developers to respond to login, logout, and video playback state changes. The changes include adding four new async callback parameters and removing a debug console.log statement from the JavaScript code.
Key Changes
- Added four new callback parameters:
OnLoginedAsync,OnLogoutedAsync,OnStartRealPlayedAsync, andOnStopRealPlayedAsync - Modified state management in
Logout()to setIsRealPlaying = falsebefore triggering the logout callback - Changed
StopRealPlay()to useInvokeVoidAsyncinstead of checking return values - Removed debug
console.logstatement from JavaScript

The method now calls InvokeVoidAsync instead of checking the return value from the JavaScript function. However, the JavaScript stopRealPlay function still returns a Promise with a boolean result. This discrepancy means potential errors from the JavaScript side will be silently ignored. The callback OnStopRealPlayedAsync is now always triggered even if the JavaScript operation fails. Consider either: (1) reverting to InvokeAsync<bool?> and checking the result, or (2) updating the JavaScript function to properly handle and throw errors.
| await InvokeVoidAsync("stopRealPlay", Id); | |
| IsRealPlaying = false; | |
| await TriggerStopRealPlay(); | |
| var result = await InvokeAsync<bool?>("stopRealPlay", Id); | |
| if (result ?? false) | |
| { | |
| IsRealPlaying = false; | |
| await TriggerStopRealPlay(); | |
| } | |
| // Optionally handle failure here (e.g., log, throw, notify user) |

The method name TriggerLogined uses incorrect grammar. "Logined" is not a valid past participle. This should be renamed to TriggerLoggedIn to match the suggested parameter name correction.

The callback name OnLoginedAsync uses incorrect grammar. "Logined" is not a valid past participle in English. Consider renaming to OnLoggedInAsync to be grammatically correct and consistent with standard English usage, or use OnLoginSuccessAsync as an alternative.
