Version 102.0.100

Namespace:  CefSharp
Assembly:  CefSharp (in CefSharp.dll) Version: 102.0.100.0 (102.0.100.0)
Syntax
bool OnJSDialog(
	IWebBrowser chromiumWebBrowser,
	IBrowser browser,
	string originUrl,
	CefJsDialogType dialogType,
	string messageText,
	string defaultPromptText,
	IJsDialogCallback callback,
	ref bool suppressMessage
)

Parameters

chromiumWebBrowser
Type: CefSharp.IWebBrowser
the ChromiumWebBrowser control
browser
Type: CefSharp.IBrowser
the browser object
originUrl
Type: System.String
originating url
dialogType
Type: CefSharp.CefJsDialogType
Dialog Type
messageText
Type: System.String
Message Text
defaultPromptText
Type: System.String
value will be specified for prompt dialogs only
callback
Type: CefSharp.IJsDialogCallback
Callback can be executed inline or in an async fashion
suppressMessage
Type: System.Boolean
Set suppressMessage to true and return false to suppress the message (suppressing messages is preferable to immediately executing the callback as this is used to detect presumably malicious behavior like spamming alert messages in onbeforeunload). Set suppressMessage to false and return false to use the default implementation (the default implementation will show one modal dialog at a time and suppress any additional dialog requests until the displayed dialog is dismissed).

Return Value

Type: Boolean
Return true if the application will use a custom dialog or if the callback has been executed immediately. Custom dialogs may be either modal or modeless. If a custom dialog is used the application must execute |callback| once the custom dialog is dismissed.
