Javascript Checkbox oncheck uncheck other checkboxes

Hello,

I have a form, with three checkboxes on it -

<table width="200" border="0" cellspacing="0" cellpadding="0">
          <tr>
            <td><input <%If (CStr((MemberDetail.Fields.Item("UK-Member").Value)) = CStr("Y")) Then Response.Write("checked=""checked""") : Response.Write("")%> name="uk" type="checkbox" id="uk" value="Y" /></td>
            <td class="chechtext">UK Member</td>
          </tr>
          <tr>
            <td><input <%If (CStr((MemberDetail.Fields.Item("Eire-Member").Value)) = CStr("Y")) Then Response.Write("checked=""checked""") : Response.Write("")%> name="Eire" type="checkbox" id="Eire" value="Y" /></td>
            <td class="chechtext">Eire Member</td>
          </tr>
          <tr>
            <td><input <%If (CStr((MemberDetail.Fields.Item("EU-Member").Value)) = CStr("Y")) Then Response.Write("checked=""checked""") : Response.Write("")%> name="EU" type="checkbox" id="EU" value="Y" /></td>
            <td class="chechtext">EU Member</td>
          </tr>
        </table>

Open in new window


I'd like to write a javascript snippet that if uk is selected (Checked) deselects any of the other two options that maybe selected. So that at any point in time only one of the checkboxes can be checked..

In essence whichever checkbox is checked, the other two aren't..

Appreciate any assistance with this -

Thanks

Simple answer is to change them to radio buttons.

If you need to use checkboxes, then here is one way you can do it.  Add an "onclick" event to each checkbox that calls a function.  This function unchecks the checkboxes and then re-checks the one that called the function.
<table width="200" border="0" cellspacing="0" cellpadding="0">
	<tr>
		<td><input name="uk" type="checkbox" id="uk" value="Y" onclick="cbxChange(this);"/></td>
		<td class="chechtext">UK Member</td>
	</tr>
	<tr>
		<td><input name="Eire" type="checkbox" id="Eire" value="Y" onclick="cbxChange(this);"/></td>
		<td class="chechtext">Eire Member</td>
	</tr>
	<tr>
		<td><input name="EU" type="checkbox" id="EU" value="Y" onclick="cbxChange(this);"/></td>
		<td class="chechtext">EU Member</td>
	</tr>
</table>
<script>
function cbxChange(cbx){
	document.getElementById('uk').checked = false;
	document.getElementById('Eire').checked = false;
	document.getElementById('EU').checked = false;

	document.getElementById(cbx.id).checked=true;
}
</script>

Hi garethtnash,

For this type of functionality, you can use Radio buttons.
Is there any specific reason for using checkboxes, because radio buttons can solves this problem without writing so much code?
