var length = 5
var checkbox = new Array(length);

checkbox[0] = &quot;0|check&quot;;

checkbox[2] = &quot;2|check&quot;;
checkbox[3] = &quot;3|empty&quot;;
checkbox[4] = &quot;4|empty&quot;;
checkbox[5] = &quot;5|check&quot;;

for (var i=0; i<=checkbox.length-1; i++)
{
if (checkbox.indexOf(&quot;check&quot;,0) >= 0)
document.forms[0].elements.checked = true;
}

um there is a Slight problem with that, my page isnt a Static HTML, it's dynamic, and it gets it's array from the ASP, the ASP does make the Javascript portion hardcode all the values of the array, but the Checkbox etc portion it's not static.

heres a small example of the checkboxes/etc generated by the ASP (the Javascript is above it since when I generate the checkboxes etc, they're put into a string, then later output to the browser so that I Could use two columns in the table)

Karl,

can your show me part of your ASP code?
if it is ASP page, it should not be difficult to do that

It would be somewhat difficult, because the list of Checkboxes, and what not in a tree format, comes from an Array generated by .GetRows from a Database, that hold certain header/left etc data to recursivily give the flow a true parent/child relation(a true parent/child is no longer true when it becoems an HTML) [sig]<p>Karl<br><a href=mailto:kb244@kb244.com>kb244@kb244.com</a><br><a href= </a><br>Experienced in : C++(both VC++ and Borland),VB1(dos) thru VB6, Delphi 3 pro, HTML, Visual InterDev 6(ASP(WebProgramming/Vbscript)<br>

currently the showchild function will spit back all the children of a checkbox I click, just to make sure my rescursion is working, and ready when I figure out how to access the checkbox's properties (like checked/unchecked) by just using the name of the checkbox I have stored in a string.

also doing this

[tt]
tree[j][2].checked = true;
[/tt]

(I've also tried, on, 1, 0, off, false, and included &quot;&quot; around them as well)

doesnt generate an error, but doesnt do anything either. [sig]<p>Karl<br><a href=mailto:kb244@kb244.com>kb244@kb244.com</a><br><a href= </a><br>Experienced in : C++(both VC++ and Borland),VB1(dos) thru VB6, Delphi 3 pro, HTML, Visual InterDev 6(ASP(WebProgramming/Vbscript)<br>

Karl,

let say.. the following HTML are generated by your ASP code
-------------------------------------------
<html>
<body>
<form>
<input type=checkbox name=&quot;0|check&quot;>
<input type=checkbox name=&quot;1|empty&quot;>
<input type=checkbox name=&quot;2|check&quot;>
<input type=checkbox name=&quot;3|empty&quot;>
<input type=checkbox name=&quot;4|empty&quot;>
<input type=checkbox name=&quot;5|check&quot;>
</form>
-------------------------------------

after it, you can place the following javascript code, the only problem is i forgot how to make that &quot;5&quot; in the for loop dynamic, i pretty sure there is a way to detect the length of elements.. or you can let ASP return a count variable tell the javascript how many element are there..


<script>
for (var i=0; i<=5; i++)
if ((document.forms[0].elements.name.indexOf(&quot;check&quot;,0)) >= 0)
document.forms[0].elements.checked = true;
}
</script>

</body>

This works great.

function ShowChild(HID, LID, status)
{
var list = '';
for(var j=0; j<=max; j++)
{
if ((tree[j][3] == HID) & (tree[j][4] == LID))
{
//Need to figure out how to reference an object using it's name in a String
//spnum += 1;
ShowChild(tree[j][0],tree[j][1], status)
//spnum -= 1;
//if (retshow != '')
// list = list + &quot;\n&quot; + spaces(spnum) + tree[j][2] + retshow;
//else
// list = list + &quot;\n&quot; + spaces(spnum) + tree[j][2];
document.all(tree[j][2]).checked = status; //test
}
}
//return list;
}

it'll only checks one level below tho [sig]<p>Karl<br><a href=mailto:kb244@kb244.com>kb244@kb244.com</a><br><a href= </a><br>Experienced in : C++(both VC++ and Borland),VB1(dos) thru VB6, Delphi 3 pro, HTML, Visual InterDev 6(ASP(WebProgramming/Vbscript)<br>
