OnJavaScriptAlert - TPdf - PDFium Delphi Component

Dipicu ketika skrip JavaScript atau XFA yang tertanam memanggil app.alert, mengizinkan host menampilkan pesan alih-alih kotak pesan default

Remarks

Set Handled to True in the handler to suppress the default Application.MessageBox call
The Result parameter receives the user-selected button code (JSPLATFORM_ALERT_RETURN_*) when Handled is True
When unassigned, a default OK/Yes/No message box with the closest matching icon is shown automatically
