onJSDialog

public boolean onJSDialog(CefBrowser browser,
                 String origin_url,
                 String accept_lang,
                 CefJSDialogHandler.JSDialogType dialog_type,
                 String message_text,
                 String default_prompt_text,
                 CefJSDialogCallback callback,
                 BoolRef suppress_message)

从接口复制的说明: CefJSDialogHandler

Called to run a JavaScript dialog. Set suppress_message 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 suppress_message 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 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.

指定者:

onJSDialog 在接口中 CefJSDialogHandler

参数:

browser - The corresponding browser.

origin_url - The originating url.

accept_lang - the accepted language.

dialog_type - the dialog type.

message_text - the text to be displayed.

default_prompt_text - value will be specified for prompt dialogs only.

callback - execute callback once the custom dialog is dismissed.

suppress_message - set to true to suppress displaying the message.

返回:

false to use the default dialog implementation. Return true if the application will use a custom dialog.

onBeforeUnloadDialog

public boolean onBeforeUnloadDialog(CefBrowser browser,
                           String message_text,
                           boolean is_reload,
                           CefJSDialogCallback callback)

从接口复制的说明: CefJSDialogHandler

Called to run a dialog asking the user if they want to leave a page. Return false to use the default dialog implementation. 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.

指定者:

onBeforeUnloadDialog 在接口中 CefJSDialogHandler

参数:

browser - The corresponding browser.

message_text - The text to be displayed.

is_reload - true if the page is reloaded.

callback - execute callback once the custom dialog is dismissed.

返回:

false to use the default dialog implementation. Return true if the application will use a custom dialog.

onResetDialogState

public void onResetDialogState(CefBrowser browser)

从接口复制的说明: CefJSDialogHandler

Called to cancel any pending dialogs and reset any saved dialog state. Will be called due to events like page navigation irregardless of whether any dialogs are currently pending.

指定者:

onResetDialogState 在接口中 CefJSDialogHandler

onDialogClosed

public void onDialogClosed(CefBrowser browser)

从接口复制的说明: CefJSDialogHandler

Called when the default implementation dialog is closed.

指定者:
