如何在select2 jQuery字段中基于选定的Multiple值显示/隐藏div

Question

I have select2 jquery dropdown which compose of two items *For Rent *For Sales If i selected For Rent a certain fields will be displayed under it same as the For sales. The problem is i don't know how i'm gonna display both fields if user selected both in dropdown.

In my code I tried to do it but when user selected just only one it displays both fields

$('#for_sales_fields').hide();
$('#for_rents_fields').hide();


$('#property-types-ids').change(function() {

  if($(this).val() == 1) {
    $('#for_sales_fields').show();
  }
  else {
    $('#for_sales_fields').hide();
  }
  if($(this).val() == 2) {
    $('#for_rents_fields').show();
  }
  else {
    $('#for_rents_fields').hide();
  }

  var test = [];
  $.each($('#property-types-ids :selected'), function(){
      test.push($(this).val());
      $('#for_sales_fields').show();
      $('#for_rents_fields').show();
  })

 }
 );

When For Sale is selected

When For Rent is selected

When both selected it should display both fields

Here is the solution for your problem:

Initially, you need to keep both div hidden, in change event. Then check the value of the selected value in property type and display your divs

 var s2 = $("#property-types-ids").select2({ placeholder: "Choose property type", tags: true }); var vals = []; vals.forEach(function(e){ if(!s2.find('option:contains(' + e + ')').length) s2.append($('<option>').text(e)); }); s2.val(vals).trigger("change"); $('#for_sales_fields').hide(); $('#for_rents_fields').hide(); $('#property-types-ids').change(function() { $('#for_sales_fields').hide(); $('#for_rents_fields').hide(); var test = []; $.each($('#property-types-ids :selected'), function(){ test.push($(this).val()); if($(this).val() == 1) { $('#for_sales_fields').show(); } if($(this).val() == 2) { $('#for_rents_fields').show(); } }) } );
