Javascript Function (Beginner)

I am trying to write a function that I can setoff by an onClick event that would check or uncheck a hidden checkbox if another checkbox is checked. The function I wrote, untested yet is this:
<script language="JavaScript">
Function chkBox(rID, fileName){
if (document.form1.(rID).checked == True;)
{
document.form1.(fileName).checked == True;
}else{
document.form1.(fileName).checked == False;
}
}
</script>
and I was thinking for the onClick event it would be like this
onClick="chkBox(<%=dB.recid%>,<%=dB.fileName%>)"
Because these values are assinged to each row as the page populates my Repeat Region.

Thanks for your help.

Dunno if this will help, but it will check all boxes and uncheck them. You can play with the script to suit your needs.

i guess if you had the script it would help huh? ;-)

<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="javascript">

</script>

</head>

<body bgcolor="#FFFFFF" text="#000000">
<form name="myform" method="post" action="">
<p><a href="#" onClick="checkAll(document.myform.list)">Check All</a> <a href="#" onClick="uncheckAll(document.myform.list)">UnCheck
All</a></p>
<p>
<input type="checkbox" name="list" value="checkbox">
A</p>
<p>
<input type="checkbox" name="list" value="checkbox">
B</p>
<p>
<input type="checkbox" name="list" value="checkbox">
C</p>
<p>
<input type="checkbox" name="list" value="checkbox">
D</p>
</form>
</body>
</html>

</jAy>

i'm not to sure what it is you are trying to do. you can't have a hidden checkbox, but you can have a hidden variable. if you wanted to toggle it, you would do something like this:

<script>
function chk(){
if(document.tmpForm.hiddenVar.value == 0 ){
document.tmpForm.hiddenVar.value = 1;
}
else{
document.tmpForm.hiddenVar.value = 0;
}
//for testing purposes only
alert(document.tmpForm.hiddenVar.value);
}
</script>

<form name="tmpForm">
<input type="hidden" name="hiddenVar" value="0">
<input type="checkBox" name="cbox" onclick="chk()">
</form>

your last statment leads me to believe you might have mutilple checkboxs with the same name. in that case if you wanted to use one to toggle the other, you would do something like this:

<script>
function chk(){
document.tmpForm.cbox[2].checked = true;
return
}
</script>

with multiple checkboxs you have an arrya of checkboxs, in the above example, when you execute this function the 2nd(actually it may be the 3rd, i believe javascript starts arrays at 0) check box will become checked. you can toggle it the same way as in the first example

You can have a hidden check box in a hidden table, as long as the table is in between the<form> tags.

The checkbox is hidden in a div = display none.

When they, the user, clicks on submit what the page will do is send every checked box to a doDelete.asp page. This page will then take every recid in Request("recid") and delete that record from the dB then it will take every Request("fileName") and delete the actual file. So when the user clicks on the checkbox, which is "recid", I want it to also select the hidden, the Filename, so that will be sent on the submit.

Changed my code:
function chkBox(recID, flName){
if (document.form1.+recID+.checked == True;)
{document.getElementById.+flName+.checked == True;}else{document.getElementById.+flName+.checked == False;}
}

Here is my onClick:

onClick="chkBox(<%=(rsPDFDel.Fields.Item("recid").Value)%>,'<%=(rsPDFDel.Fields.Item("pdfFilename").Value)%>');return false;"

I get Object Expected
