Hi,

I want to disable a set of checkbox based on selection of one textbox and enable the disabled ones if the checkbox is unchecked.

In the code below. If someone checks the checkbox for project cost under change this parameter then checkbox for project cost under Generate simulated value for this param should be disabled and all the checkboxes under change this parameter should be disabled except for checked one. Similarly this should be done each parameter like Project cost,avg hours,Project completion date, hourly rate etc.

One way i could think of was of on the click function disable each checkbox by the id. Is there a better way of doing it?

 <table>
<tr>
 <td></td>
 <td></td>
  <td>Change this parameter</td>
  <td>Generate simulated value for this param</td>

 </tr>
 <tr>
  <td>Project cost</td>
  <td><input type ="text" id ="pc"/></td>
  <td><input class="change" type="checkbox" name="chkBox" id="chkBox"></input></td>
  <td><input class="sim" type="checkbox" name="chkBox1" id="chkBox1"></input></td>

   </tr>
<tr>
<td>Avg hours</td>
<td><input type ="text" id ="avghrs"/></td>
<td><input class="change" type="checkbox" name="chkBoxa" id="chkBoxa"></input></td>
<td><input class="sim" type="checkbox" name="chkBox1a" id="chkBox1a"></input></td>

</tr>

<tr>
<td>Project completion date</td>
<td><input type ="text" id ="cd"/></td>
<td><input class="change" type="checkbox" name="chkBoxb" id="chkBoxb"></input></td>
<td><input class="sim" type="checkbox" name="chkBox1b" id="chkBox1b"></input></td>

</tr>
<tr>
<td>Hourly rate</td>
<td><input type ="text" id ="hr"/></td>
<td><input class="change" type="checkbox" name="chkBoxc" id="chkBoxc"></input></td>
<td><input class="sim" type="checkbox" name="chkBox1c" id="chkBox1c"></input></td>

</tr>
</table>
