well, you can do this in two ways:

1. (Not a good one) ids for checkboxes in checkboxlists are created like
this:
"nameOfAcheckbo xlist_nextNumbe r"

so you can loop

for (i = 0; i < number; i++)
{
if (document.getEl ementByID("chec kboxlistName_" + i ).checked)
{
//do something
}
}

or

2. (Better one) On server side create a javascript array that contains
checkbox'es .ClientID
And on a client side loop through this array.

for (i = 0; i < idsArray.length ; i++)
{
if (document.getEl ementByID(idsAr ray[i]).checked)
{
//do something
}
}

hope this helps.

What i can advice you is try viewing the source code of the page and you
will see the
Id created for the checkboxlist which i guess it would be similar to what
you posted..
Is you Checkboxlist in any other control or are you databinding your
Checkboxlist
Post more info

The code generated is...

<table id="CheckBoxLis t1" border="0" style="Z-INDEX: 104; LEFT: 384px;
POSITION: absolute; TOP: 112px">
<tr>
<td><input id="CheckBoxLis t1_0" type="checkbox"
name="CheckBoxL ist1:0" /><label for="CheckBoxLi st1_0">one</label></td>
</tr><tr>
<td><input id="CheckBoxLis t1_1" type="checkbox"

I'm not sure what your problem is. When a checkbox is checked, it has a
value of 'on' - when it's not, it doesn't...

<script>

if(document.get ElementById('Ch eckBoxList1_0') .value == 'on')
{
alert('Checked' );
}
else
{
alert('Not checked');
}

</script>
