Question

I have several DIVs on a page.

Inside these DIVs I have several form-elements such as inputs and selects.

I also have two radio buttons.

I want whenever radio nr2 is clicked, to disable ALL OTHER ELEMENTS inside the active DIV.

Here is one of my DIVs and its content:

<div id="test">

<select name="cars_mile_to" id="cars_mile_to" style="width: 130px; margin-bottom: 5px;">

                <option id="Miltal Till" value="1000000" class="nav_option_main" selected>-- Miltal Till --</option>
                <option id="500" value="500">500</option>
                <option id="1000" value="1000">1 000</option>

                <option id="45000" value="45000">45 000</option>
                <option id="50000" value="50000">50 000</option>
                <option id="1000000" value="900000">Över 50 000</option>

              </select>

              <select name="cars_fuel" id="cars_fuel" style="width: 160px; margin-bottom: 5px;">

                <option id="Drivmedel" value="Drivmedel" class="nav_option_main" selected>-- Drivmedel --</option>
                <option id="Bensin" value="Bensin">Bensin</option>
                <option id="Diesel" value="Diesel">Diesel</option>
                <option id="Miljöbränsle" value="Miljöbränsle">Miljöbränsle</option>
                <option id="EL" value="EL">EL</option>

              </select>

              <br />

              <input type="radio" name="cars_action" id="cars_action_sell" value="Säljes" checked>
                     <font face="Arial, Helvetica, sans-serif" style="font-size:14px; font-weight:bold;">Säljes</font>
              <input type="radio" name="cars_action" id="cars_action_buy" value="Köpes">
                     <font face="Arial, Helvetica, sans-serif" style="font-size:14px; font-weight:bold;">Köpes</font> 

      </div>

I want as I mention above, that whenever the radio with the id=cars_action_buy is selected, to disable all other possible elements inside the current DIV.
Perhaps by adding a js function?

Thanks

Answer 1

In javascript you can simply use the disabled=”true” attribute. So, in the onselect handler you can do something like:

document.getElementById('cars_mile_to').disabled = true;

for each of the elements you want to disable. If they are always in the same div, then you can simply loop over the elements, ignoring the radio group.
