Members

Accept

The host may run this to respond with OK to confirm, prompt, and beforeunload dialogs.

public HRESULT Accept()

Do not run this method to indicate cancel. From JavaScript, this means that the confirm and beforeunload function returns TRUE if Accept is run. And for the prompt function it returns the value of ResultText if Accept is run and otherwise returns FALSE.

get_DefaultText

The second parameter passed to the JavaScript prompt dialog.

public HRESULT get_DefaultText(LPWSTR * defaultText)

The result of the prompt JavaScript function uses this value as the default value.

The caller must free the returned string with CoTaskMemFree. See API Conventions.

get_Kind

The kind of JavaScript dialog box.

public HRESULT get_Kind(COREWEBVIEW2_SCRIPT_DIALOG_KIND * kind)

alert, confirm, prompt, or beforeunload.

get_Message

The message of the dialog box.

public HRESULT get_Message(LPWSTR * message)

From JavaScript this is the first parameter passed to alert, confirm, and prompt and is empty for beforeunload.

The caller must free the returned string with CoTaskMemFree. See API Conventions.

get_ResultText

The return value from the JavaScript prompt function if Accept is run.

public HRESULT get_ResultText(LPWSTR * resultText)

This value is ignored for dialog kinds other than prompt. If Accept is not run, this value is ignored and FALSE is returned from prompt.

The caller must free the returned string with CoTaskMemFree. See API Conventions.

get_Uri

The URI of the page that requested the dialog box.

public HRESULT get_Uri(LPWSTR * uri)

The caller must free the returned string with CoTaskMemFree. See API Conventions.

GetDeferral

Returns an ICoreWebView2Deferral object.

public HRESULT GetDeferral(ICoreWebView2Deferral ** deferral)

Use this operation to complete the event at a later time.

put_ResultText

Sets the ResultText property.

public HRESULT put_ResultText(LPCWSTR resultText)
