If first checkbox checked, check all 1

[SoonerNation]

I tried the solution offered in archived thread thread216-881568 but it doesn't seem to work for me.

Like the original poster, I have a master checkbox and need all other checkboxes in the form to set to the same value as the master, no matter their current value.

Any help is very much appreciated.

I copied the following script exactly:

<script type="text/javascript">
function checkAll(el) {
var isChecked = el.checked;
var form = el.form;
var els = form.elements;

for (var x = 0; x < els.length; x++) {
if (el != els[x]
&& els[x].type
&& els[x].type.toLowerCase() == "checkbox") {
// set to same state as master checkbox
els[x].checked = isChecked;

if (isChecked) {
// keep checked
els[x].onclick = function(){this.checked = true;}
}
else {
// normal behavior
els[x].onclick = null;
}
}
}
}
</script>
and used it in this context:

<form name="EMailList" action="EMailChecked.cfm" method="POST">
<tr>
<td class="ColumnHeadingCell" colspan="4">
<div align="Left"><input type="Checkbox" name="Master" onclick="checkall(this);">&nbsp;All</div>
<div align="center">
<input type="submit" name="B1" value="EMail Checked">
<input type="reset" name="B2" value="Clear Checks">
</div>
</td>
</tr>
<tr>
<td class="ColumnHeadingCell">
&nbsp;
</td>
<td class="ColumnHeadingCell">
<a href="email.cfm?mOrder=Name" class="InColumnHeader">Sort by Name</a>
</td>
<td class="ColumnHeadingCell">
<a href="email.cfm?mOrder=Department" class="InColumnHeader">Sort by Department</a>
</td>
<td class="ColumnHeadingCell">
<a href="email.cfm?mOrder=Location" class="InColumnHeader">Sort by Location</a>
</td>
</tr>
<cfoutput query="BinkleyUser">
<tr>
<td class="NormalCell">
<input type="Checkbox" name=#Trim(BinkleyUser.UserLogin)#>&nbsp;
</td>
<td class="NormalCell">
<cfset mName='Send email to '&Trim(BinkleyUser.FirstName)&' '&Trim(BinkleyUser.LastName)>
<a href="mailto:#BinkleyUser.EMail#" class="Special" title="#mName#">#UCase(BinkleyUser.FirstName)# #UCase(BinkleyUser.LastName)#</a>
</td>
<td class="NormalCell">
#UCase(BinkleyUser.Office)#
</td>
<td class="NormalCell">
#UCase(BinkleyUser.Location)#
</td>
</tr>
</cfoutput>
</form>
