Question

Little help on making a function which disables some form elements

Answer 1

A:

I'd add an onselect attribute to your radio button to call some javascript function. Within the javascript function, disable the IDs that you wish to disable.

<input type="radio" name="cars_action" id="cars_action_buy" value="Köpes" onselect="Disable()">

<script type="text/javascript">
function Disable()
{
  var myVar = Document.GetElementByID('<element ID name>');
  myVar.Disabled = true;
  //do this for each you wish to disable
}
</script>

Answer 2

A:

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.

Answer 3

A:

Using jQuery, something like this could work

$("#cars_action_buy").change(function() {
    var div = $(this).
    if ($("#cars_action_buy").val() == "Köpes") {
        $("#test select,#test input:not(#cars_action_buy)").attr("disabled", "disabled");
    }
});

Answer 4

A:

If you're up for using a library like jQuery, this this will work.

Paste this above your code and try it out in your browser.

<script type="text/javascript" src="http://www.google.com/jsapi"&gt;&lt;/script&gt;
<script type="text/javascript"> google.load("jquery", "1.3.2"); </script>
<script type="text/javascript">
  $(function()
  {
    $('#cars_action_buy').click( function( event )
    {
      var $elem = $(this);
      if ( $elem[0].checked )
      {
        console.log( $elem.parent().find( 'input, select' ) );
        $elem.parent().find( 'input, select' ).not( $elem ).attr( 'disabled', 'disabled' );
      }
    });  
  })
</script>
