Question

Help with simple script

Asked by: kmartin7

Hi,

I haven't javascripted in a while, and I am trying to toggle a table row's background color when a checkbox is checked, then return the row back to its original color if the checkbox is unchecked. Please help with my code:

<script type="text/javascript">
		function change(id) {
			var tr=document.getElementById(id);
			tr.style.backgroundColor=(id.checked)? 'white' : 'red';
		}
</script>

HTML Snippet.

The above will change the row color to red, but it won't toggle back to white.

<tr id="_5">
          <td class="frmSides">5</td>
							
          <td valign="top">NUT, HEX, M6 X 1, L5.2 MAX, CL8, ZP, ISO4032</td>
							
          <td valign="top">NSL</td>
