This is a very common code, and it is very simple. In this case, you can use a hidden input to check which records are selected when you click the delete button, put the IDs of these records in the hidden input. Then submit. You can also set a checkbox and a hidden input. When you select a checkbox, the corresponding hidden input value is set to the record ID. If you cancel the operation, it is set to null. The several den inputs use the same name.
For example, rs is the returned record set:
Do until rs. eof
'Write checkbox
Response. write "<input type = checkbox onclick =" "if (this. checked) document. all. todel _ "& rs (" id ")&". value = '"& rs (" id ") &"'; else document. all. todel _ "& rs (" id ")&". value = ''" ">"
'Write den
Response. write "<input type = hidden name = todel id = todel _" & rs ("id") & ">"
...... 'Additional processing code
Rs. movenext
Loop
To process the submitted code, you only need to check the request. form ("todel"), request. querystring ("todel"), or request ("todel. The records won't be deleted after the ID number is obtained. Isn't it possible?
