checkbox 多选删除

This is a very common code and very simple. In your case, you can use a hidden input. When you click the delete button, you can detect which record checkboxes are selected and put the IDs of these records into In that hidden input. Then submit. You can also have a checkbox and a hidden input. When a checkbox is selected, the corresponding hidden input is set to the ID of the record. If canceled, it will be left empty. These hidden inputs use the same name.

For example, rs is the returned record set:
do until rs.eof
'Write checkbox
response.write ""
'Write hidden
response.write ""
……'Other processing Code
rs.movenext
loop

To process the submitted code, just detect request.form("todel") or request.querystring("todel") or request("todel") . The record will not be deleted after obtaining the ID number, so that should be impossible, right?
