show/hide a <TR> with a checkBox

How can I show or hide a table row depending on the status of a checkbox?

I have this - the table and form is placed in a layer <div></div>:

<table>
<tr>
<td>show/hide <input type="checkbox" name="toggle" value="1"><td>
<tr  style="display:none;" id="telTR">
<td class="dynaContent">Tel.<input type="text" name="tel" size="18">
</td>
</tr>
<table>

If I check the checkbox "toggle" the next row should be visible. If I uncheck it, the row should again disappear.

Must only work with IE 4+ NS 6

Thank you in advance

If the rows look like this: <TR id="therow" style="display:inline">
You do the check boxes this way: <input type="checkbox" onClick="toggle('therow')"

Then the function is:

<script language="JavaScript">
<!--
   function toggle(target)
   {
      obj=(document.all) ? document.all[target] : document.getElementById(target);
      obj.style.display=(obj.style.display=='none') ? 'inline' : 'none';
   }
//-->
</script>

I only have IE5.5 and MOZ1.0 installed so don't know i fit works for NS6.  MOZ1.0 screws up the rendering, so NS6 might have a problem with it.

Hi

Thank you very much for the rapid - and good - solution!

Here's my testing result:

PC/IE 6 => just fine
PC / NS 6.2 => fine, but additional empty rows are added if the toggle button is used several times

Mac/IE 5 => just fine
Mac/NS 6 => doesn't work

Kind regards

I was afraid NS 6 would be a problem.  MOZ1 was doing the same thing with sticking in the extra rows.  If I have some time next week I'll install 6.2 and see if I can find a way to clean it up. If I come up with something I'll post it here.

I have tried the above code, and it works well, but can anyone tell me how I modify it so that the table row is initially hidden, and then displayed (toggled) when the box is checked?

change the <tr> tag to this:

<TR id="therow" style="display:none">

I would like to hide and show a row in my table based upon the selected value, for example, when users select 'other' in the dropdown list, this row shows, and hide otherwise.

Your help is highly appreciated
