[dancer-users] how to change drop down list on different tabs

[Daniel Perrett]

Strictly this is a jQuery question rather than a Dancer question, but:

Assuming you’re making an ajax request to get the data, where data is of the form

[['kidney',1],['liver',2],['noggin',3]]

I’m assuming this structure because this is what your template expects – then you could achieve this by code in the success function in your $.ajax call along the lines of:

  var selectElement = $('select[name="tissue"]').first().empty();

  $.map(data, function(tissue){
    selectElement.append( $('<option/>').attr('value',tissue[1]).text(tissue[0]))
  } );

In live production code you would probably want to use a better selector for the select element in case you have multiple panels.

… however, if the tabs control the contents of the form, are you sure your form belongs outside the tabs and not inside them?

Changing the drop down can be done most easily client-side. Therefore, I'd use jQuery to switch tabs and change the drop down.

--john

I am able to get the data needed, but how to use jQuery to update the drop down, I.e. The option element in the template?

It is a list, not a single value.

Can anybody give me a hint please?

Many thanks,
Wendy

Hi,

I have a template:
The first part is a form with a drop down list.
The second part of the template consists different tabs.

By selecting from the list, it shows different content in the second part of the template.

But I want to change the drop down list content when switch between tabs. How can I do it?

The simplified version of the codes look like:

  <div class="panel">
    <h3 >Select a tissue specific analysis: </h3>
    <div class="filt_options">
       <form action=“/someaction/&" method="post" autocomplete="off">
           <select name="tissue" class="tissue_selector">
                 <?pl foreach my $tissue ( @$tissues ){ ?>
                    <option value="[== $tissue->[1] =]"> [== $tissue->[0] =]</option>
               <?pl } ?>
        </select>
    </form>
    </div>

   <div class="sub_data" id="tissue_selection”>
       <ul class="tabs">
          <li><a href="#t_first">Overview</a></li>
         <li><a href=“#t_second”>Plot</a></li>
     </ul>

  <div id="t_first" class=“overview”>
  </div>

  <div id=“t_second” class="plot">
  </div>
</div>
</div>

Many thanks,
Wendy
