DomBlur, DomFocus, DomMouseHandler, DomClick handlers.

[lofti198]

Hello! For GeckoFX I could handle following events: DomBlur, DomFocus, DomMouseHandler, DomClick handlers. What is best approach to handle them for Cefsharp? Using JavascriptMessageReveived or another way?

Using JavascriptMessageReveived or another way?

That's one way. Another is to use https://github.com/cefsharp/CefSharp.Dom#dom-access

//Event Handler
//Expose a function to javascript, functions persist across navigations
//So only need to do this once
await devToolsContext.ExposeFunctionAsync("jsAlertButtonClick", () =>
{
    _ = devToolsContext.EvaluateExpressionAsync("window.alert('Hello! You invoked window.alert()');");
});

var jsAlertButton = await devToolsContext.QuerySelectorAsync<HtmlButtonElement>("#jsAlertButton");

//Write up the click event listner to call our exposed function
_ = jsAlertButton.AddEventListenerAsync("click", "jsAlertButtonClick");
