Why didn't you respond when you clicked the button? Is there something wrong with the value passed by father and son?

clicking the button now will not pop up the dialog box. What"s wrong?

Hello, landlord! Because the parameter name passed by your to the child component is not correct , the child component defines props-> addBookOnoff , while the parent component passes dialog-form-visible . So the dialog box will not be displayed.
