Displaying/Concealing specific choices using jQuery

Greetings! I am in need of some assistance with my coding query. I have been working on a piece of code where selecting 'x' should reveal another dropdown, which seems to be functioning correctly. However, if I navigate three dropdowns deep and then select a different primary dropdown option, the previously displayed dropdown does not hide as expected.

For instance:

If you test the code snippet provided, you will notice that if you choose India, then Orissa, followed by Nal - but proceed to change India to America, Nal remains visible in the final dropdown. The same issue occurs if you initially select America - California - MRK or KRK.

Answer №1

It's recommended to trigger the second select box when the first select box is changed. I have temporarily commented out $("#select3").hide(); for testing purposes.

$('#select2').trigger('change');

I believe this solution can be helpful for you.

$("#select1").change(function() {
  
  //$("#select3").hide();
  if ($(this).data('options') == undefined) {
    $(this).data('options', $('#select2 option').clone());
  }
  var id = $(this).val();
  var options = $(this).data('options').filter('[data-value=' + id + ']');
  $('#select2').html(options).show();
  if($('#select3').is(':visible'))
        $('#select2').trigger('change');
});


$("#select2").change(function() {
  if ($(this).data('options') == undefined) {
    $(this).data('options', $('#select3 option').clone());
  }
  var id = $(this).val();
  var options = $(this).data('options').filter('[data-value=' + id + ']');
  $('#select3').html(options).show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">
</script>
<select name="select1" id="select1">
    <option value="">Select Country</option>
    <option value="india">India</option>
    <option value="america">America</option>
</select>


<select name="select2" id="select2" style="display: none;">
    <option value="">Select State</option>
    <option data-value="india" value="orissa">Orissa</option>
    <option data-value="india" value="telangan">Telangan</option>
    <option data-value="america" value="america">USA</option>
    <option data-value="america" value="america">California</option>
</select>

<select name="select3" id="select3" style="display: none;">
    <option value="">Select city</option>
    <option data-value="orissa">Nal</option>
    <option data-value="orissa">Mir</option>
    <option data-value="telangan">Hyd</option>
    <option data-value="telangan">Vija</option>
    <option data-value="america">KRK</option>
    <option data-value="america">MRK</option>
</select>

To make it simple, use the .hide() function to hide the third <select> element when there is a change event on the first <select> element.

$("#select1").change(function () {
    $('#select3').hide();
    //Add the rest of your code here
});


$("#select1").change(function() {
  $('#select3').hide();

  if ($(this).data('options') == undefined) {
    $(this).data('options', $('#select2 option').clone());
  }
  var id = $(this).val();
  var options = $(this).data('options').filter('[data-value=' + id + ']');
  $('#select2').html(options).show();
});


$("#select2").change(function() {
  if ($(this).data('options') == undefined) {
    $(this).data('options', $('#select3 option').clone());
  }
  var id = $(this).val();
  var options = $(this).data('options').filter('[data-value=' + id + ']');
  $('#select3').html(options).show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">
</script>
<select name="select1" id="select1">
<option value="">Select Country</option>
<option value="india">India</option>

<select name="select2" id="select2" style="display: none;">
<option value="">Select State</option>
<option data-value="india" value="orissa">Orissa</option>
<option data-value="india" value="telangan">Telangan</option>
<option data-value="america" value="america">USA</option>
<option data-value="america" value="america">California</option>
</select>

<select name="select3" id="select3" style="display: none;">
<option value="">Select city</option>
<option data-value="orissa">Nal</option>
<option data-value="orissa">Mir</option>
<option data-value="telangan">Hyd</option>
<option data-value="telangan">Vija</option>
<option data-value="america">KRK</option>
<option data-value="america">MRK</option>
</select>

Answer №5

To establish a connection between the dropdown menus, one method is to utilize data attributes that allow them to communicate with each other.

The code provided below is just a demonstration and may require modification before implementation. It serves as an example of the concept:

<select class="select-elem" name="select1" data-childselect="select2" data-parentselect="" ></select>
<select class="select-elem" name="select2" data-childselect="select3" data-parentselect="select1" ></select>
<select class="select-elem" name="select3" data-childselect="" data-parentselect="select2" ></select>

Additionally, jQuery can be used to toggle the visibility of the relevant dropdowns:

$(".select-elem").on("click", function () {
    var p = $(this).data("parentselect");
    var c = $(this).data("childselect");

    // display the child 
    $("[name=" + c + "]").show();

});
