jQuery Show a Textbox When an Option is Selected

Question

I have the following code:

<select>
<option value="Type 1">Type 1</option>
<option value="Type 2">Type 2</option>
<option value="Type 3">Type 3</option>
<option value="Other">Other</option>
</select>

<input type="text" id="other" />

What I want to do is using jQuery make the textbox below hidden by default, and then show it if a user selects the other option from the dropdown.

Answer 1

<select id="sel">
<option value="Type 1">Type 1</option>
<option value="Type 2">Type 2</option>
<option value="Type 3">Type 3</option>
<option value="Other">Other</option>
</select>

<input type="text" id="other" style="display: none;" />

$('#sel').change(function() {
    $('#other').css('display', ($(this).val() == 'Other') ? 'block' : 'none');
});

Answer 2

Try this:

<select id="selectbox_id">
<option value="Type 1">Type 1</option>
<option value="Type 2">Type 2</option>
<option value="Type 3">Type 3</option>
<option value="Other">Other</option>
</select>

<input type="text" id="other" />

JQuery:

$(function(){
  // hide by default
  $('other').css('display', 'none');

  $('selectbox_id').change(function(){
   if ($(this).val() === 'Other') {
     $('other').css('display', 'block');
   }
 });
});

This is what I have:

            $(function () {
                $('#other').css('display', 'none');

                if ($('.ebpselect').val() === '21') {
                    $('#other').css('display', 'block');
                }
                else {
                    $('#other').css('display', 'none');
                }
                $('.ebpselect').change(function () {
                    if ($(this).val() === '21') {
                        $('#other').css('display', 'block');
                    }
                    else {
                        $('#other').css('display', 'none');
                    }
                });

            });

No need for any css here.

$('#sel').change(function() {
    var selected = $(this).val();
    if(selected == 'Other'){
      $('#other').show();
    }
    else{
      $('#other').hide();
    }
});
