ASP Delete code for multiple complex options

A very simple way is to write the name of the checkbox the same,
When you receive it, you will receive a string separated by a half-width ","
The split function is then separated into an array,
And then read out each array of data, delete.

This method is not really deleted together, but is deleted individually.
After the run, the data disappears together, yes,
But after a piece is deleted, the final result is displayed.

<script language= "JavaScript" >
<!--
function Checkall (form) {
for (Var i=0;i<form.elements.length;i++) {
var check = Form.elements[i];
if (check.name!= ' chk_all ') check.checked = form.chk_all.checked;
}
}
-->
</script>
<form method= "POST" action= "xxx.asp" name= "Test" >
<input type= "checkbox" Name= "Chk" value= "1" > select 1
<input type= "checkbox" Name= "Chk" value= "2" > select 2
<input type= "checkbox" Name= "Chk" value= "3" > select 3
<br><br>
<input type= "checkbox" Name= "Chk_all" value= "on" > I want to select all
</form>
The above is the front desk form.
Background Delete:
<%
id = request.form ("chk") ' will get a string separated by half corner ', '
IDS = Split (ID, ",")
For all AA in IDs
Conn.execute ("delete ... where id = AA")
Next
