IE causing issues with jQuery select trigger functionality

My approach involves utilizing a select dropdown to trigger various events by assigning unique classes to each select option. Here is an example :

<select name='topic' class='long box validate-select'>
   <option value="null">Questions?</option>
   <option value='First' class='select1'>Question 1</option>
   <option value='Second' class='select2'>Question 2</option>
</select>

<div id="faq1"> - </div>
<div id="faq2"> - </div>

<script>
    $(document).ready(function() {
        $('option.select1').click(function(){
            $('#faq1').fadeIn('fast');
            return false;
        });
        $('.select2').click(function(){
            $j('#faq2').fadeIn('fast').siblings().hide();
            return false;
        });
    });
</script>

Although this method functions correctly in Firefox, it does not produce the desired result in Internet Explorer (versions 7 and 8). Is there anyone who can suggest modifications that will work across all browsers, including IE?

Answer №1

Instead of using the .change() on an element, consider attaching it to the select list.

$("select[name='topic']").change(function(){
   if($(this).val() === "First"){
     $('#faq1').fadeIn('fast');
   }
   if($(this).val() === "Second"){
     $j('#faq2').fadeIn('fast').siblings().hide();
   }
});

Answer №2

It may not be reliable to depend on the click event for an option element. Here is a suggested approach:

<select id="myselect" name='topic' class='long box validate-select'>
  <option value="null">Questions?</option>
  <option value='First' class='select1'>Question 1</option>
  <option value='Second' class='select2'>Question 2</option>
</select>
<div id="faq1" class="faq">
  question one
</div>
<div id="faq2" class="faq">
  question two
</div>
<script type="text/javascript">
  $(function () {

    $('.faq').hide();

    $('#myselect').change(function () {

      $('.faq').hide();
      switch ($('#myselect option:selected').val()) {
        case 'First':
          $('#faq1').fadeIn('fast');
          break;
        case 'Second':
          $('#faq2').fadeIn('fast');
          break;
      }

    });

  });

</script>

onclick triggers on the entire dropdown element, not on each separate item.

Answer №4

While I share the same general answer as others, there is an additional approach that can streamline your code when dealing with multiple dropdown options. By simply adjusting the values within your dropdown menu, you can eliminate the need for extensive if or case statements.

For example, take a look at http://jsfiddle.net/UQKBQ/2/. The onchange function for the second dropdown is much more concise compared to the first.

The key line here is:

$('#'+this.value).fadeIn('fast').siblings().hide();

This line utilizes the selected value from the dropdown to generate the corresponding div ID that should be displayed. While this method may not always be applicable, especially in cases where a switch statement is necessary, for situations where there is a direct one-to-one mapping like this, storing the element ID directly in the dropdown's value can greatly reduce the amount of coding required (or copying and pasting).
