Hi I have a form which has about 50 check boxes. However some of those checkboxes are between a divtag of id=childrensgroup.

Is there any way in Javascript that I can click a checkbox called "Select all checkboxes in the childrens group" outside the DIV tag which will then select all the checkboxes between the div tag with id=childrensgroup.

Thanks for any help.

yup,

u can read through the Div's child nodes.

can i have the HTML insde the Div(an example)?

another option would be to name the checkboxes something like this:
Grp1
Grp2

etc. now u can browse through the items in a form using elements() method of the form and check the checkboxes accordingly...

Here is the code. I basically need some javascript which will tick all the checkboxes between the div with id=childrens group. Any ideas guys?


Code: 
<div id="childrensgroup" style="display:none;">
<%
intRecordCount = 0							
if not Interest3RS.EOF then
	while not Interest3RS.eof
	
%>
<div class="rSBTT"><div class="rSKNSLC"><label for="05yes"><%=Interest3RS("Title")%></label></div>
	<div class="rSNSRC"><input type="checkbox" id="05yes" name="interest" tabindex="71" value="<%=Interest3RS("InterestID")%>" />
		</div>
	<div class="cF">&nbsp;Yes </div>
</div>
<div class="sV9"></div>
<%							
	Interest3RS.MoveNext
	wend
End If													
%>
</div>

a small example:
Code: 
<script>
function CheckAll()
{
 TheVal=document.forms[0].DivName.value
 TheAction=true
 if(document.forms[0].ActionType[1].checked)
  TheAction=false

 TheDiv=document.getElementById("Div"+TheVal)
 for(i=0;i<TheDiv.childNodes.length;i++)
 {
   TheChildNode=TheDiv.childNodes[i]
   if(TheChildNode.type=="checkbox")
    TheChildNode.checked=TheAction
 }
}
</script>
<body>
<form>
<div id="Div1">
1	<input type="checkbox">
	<input type="checkbox">
	<input type="checkbox">
	<input type="checkbox">
</div>

<div id="Div2">
2	<input type="checkbox">
	<input type="checkbox">
	<input type="checkbox">
</div>

Div to work with: <input type="text" name="DivName" value="1"><br>
Action to perform: <input type="radio" name="ActionType" value="true">Check <input type="radio" name="ActionType" 

value="false">UnCheck<br>

<input type="button" value="Check All" onclick="CheckAll()">
</form>
</body>

thta is just the concept, u could try this:
Code: 
<script>
function CheckAll(TheDiv,TheType)
{
 
 for(i=0;i<TheDiv.childNodes.length;i++)
 {
   TheChildNode=TheDiv.childNodes[i]
   if(TheChildNode.type=="checkbox")
    TheChildNode.checked=TheType
 }
}
</script>
<body>
<form>
<div id="Div1">
1	<input type="checkbox" onclick="CheckAll(this.parentNode,this.checked)"> Check All<br>
	<input type="checkbox">
	<input type="checkbox">
	<input type="checkbox">
</div>

<div id="Div2">
2	<input type="checkbox" onclick="CheckAll(this.parentNode,this.checked)"> Check All<br>
	<input type="checkbox">
	<input type="checkbox">
	<input type="checkbox">
</div>

</form>
</body>

Click to expand...

if it's simple you want, this is about as uncomplex as you can make it:

Code: 
var cbs = document.getElementById('childrensgroup');
for (var loop=0; loop<cbs.length; loop++)
   if (cbs[loop].type == 'checkbox') cbs[loop].checked = true;

Hope this helps,
Dan

Hi thanks thats a lot better. Im tryig to integrate this into my code, however it still isnt working.... heres what I've got. I think the reason it might not be working is because there are still divs between the parent DIV i am trying to parse.

Code: 
<html>
<head>
<script>

function CheckAll(TheDiv,TheType)
{
alert(TheDiv)
				
for(i=0;i<TheDiv.childNodes.length;i++)
{
TheChildNode=TheDiv.childNodes[i]
if(TheChildNode.type=="checkbox")
	TheChildNode.checked=TheType
}
}

</script>
</head>

<body>
<div id="childrensgroup">
<input type="checkbox" onclick="CheckAll(this.parentNode,this.checked)" ID="Checkbox6" NAME="Checkbox1"> Check All<br>
<%
intRecordCount = 0							
if not Interest3RS.EOF then
	while not Interest3RS.eof
	
%>
<div class="rSBTT"><div class="rSKNSLC"><label for="05yes"><%=Interest3RS("Title")%></label></div>
	<div class="rSNSRC"><input type="checkbox" id="05yes" name="interest" tabindex="71" value="<%=Interest3RS("InterestID")%>" />
		</div>
	<div class="cF">&nbsp;Yes </div>
</div>
<div class="sV9"></div>
<%							
	Interest3RS.MoveNext
	wend
End If													
%>
</div>
</body>
</html>

any ideas?

BillyRayPreachersSon thanks for that but is the fact i have divs within divs going to be a problem or will the code just check all the checkboxes between childrens group?

u have to take an alternative approach then,

try this:
Code: 
<script>
function CheckAll(TheName,TheType)
{
	TheElem=document.forms[0].elements
	for(i=0;i<TheElem.length;i++)
	{
		if(TheElem[i].name==TheName)
		{
			TheElem[i].type=="checkbox"?TheElem[i].checked=TheType:""
		}
	}
}
</script>
<body>
<form>
<div id="Div1">
1	<input type="checkbox" onclick="CheckAll('Chk1',this.checked)"> Check All<br>
	<input type="checkbox" name="Chk1">
	<input type="checkbox" name="Chk1">
	<input type="checkbox" name="Chk1">
</div>

<div id="Div2">
2	<input type="checkbox" onclick="CheckAll('Chk2',this.checked)"> Check All<br>
	<input type="checkbox" name="Chk2">
	<input type="checkbox" name="Chk2">
	<input type="checkbox" name="Chk2">
</div>

</form>
</body>

You asked for code to check ALL checkboxes within the div with an id of "childrensgroup".

If you have div elements withiin that div, and they contain checkboxes, then those checkboxes ultimately are inside the outer div, and so still fall inside the original remit.

If you don't want chckboxes inside other divs (which are inside the original div) checked, then you need to be more specific about your requirements, instead of saying "all" checkboxes.

Dan - I want ALL checkboxes within the childrensgroup DIV checked regardless of whether they are within other divs.

Dan I have tested your theory by removing all my DIV tags nested in the DIV id=childrensgroup and when there are no nested DIV's the function works, therefore the problem lies with the fat that there are nested divs!

Hmmmm How to get around this!
