Recently, I have encountered a strange problem when changing other people's programs. There is a SELECT but the NAME attribute is generated by the program loop. The variable is INT, so a number such as 0 is generated. VALUE can be obtained through the request object, but I want to use document.form1 now. 0.value way to get the value of this SELECT !!
