我有3个选择选项。如果用户可以单击“添加更多人才”，则会生成动态选择选项，该选项也会生成动态选项。

如果我点击新添加的选项中的第一个选择选项。第二个选择选项也会更改。 This happends

这是我的代码

<div class="row" id="talentcontainer">
                        <div class="col s3">
                          {!! Form::select('category[]', ['Select Category' => 0], null, ['class' => 'browser-default', 'id' => 'category']) !!}

      i++;
    });

    $("#talentcontainer").on("click", '#removetalent',function (event) {
      $("#temprow").remove();
    });

    $(".wrap").on("click", '#removetalent',function (event) {
      var tal_cal = $(this).data("id");
      $.ajax({
            url: "{{ URL('/removeTalent/') }}",
            method: "GET",
            data: {tal_cal:tal_cal},
            success: function(data){
                console.log(data);
                $("#preload").remove();
            }
          });
      });
  });

我想要的是每次我在第一个选择选项时选择。同一行的第二个选择选项应该只受影响，而不是第二行。

我知道这行代码就是为什么它也改变了第二行选择选项，但我怎么做呢？

$('#talentcontainer').on('change', '.category', function(event) {
        var tal_cal = $(this).val();
        $.ajax({
            url: "{{ URL('/revealSubCategory/') }}",
            method: "GET",
            dataType: "json",
            data: {tal_cal:tal_cal},
            success: function(data){
                var target = $(event.target);
                console.log(target);
                var next_id = $('.subcategory');
                console.log(next_id);
                // var categoryID = $(event.target).attr('id');
                // var tid = event.delegateTarget.children[3].children[1].children[0].id;
                // var talentID = $("[class^=talent]").attr('id');
                // console.log(tid);
                $(".subcategory").empty().html(' ');
                $.each(data, function(key, value) {
                    $(next_id).append($("<option></option>").attr("value", value).text(value));
                });
                $(next_id).material_select();
                // $("#talent").html(data);
            }
          });
      });

请赐教。

您正在使用.subcategory作为选择器，它确实影响了所有select个有subcategory类的人 你可以尝试

$('#talentcontainer').on('change', '.category', function(event) {
        var that = this;
        var tal_cal = $(this).val();
        $.ajax({
            url: "{{ URL('/revealSubCategory/') }}",
            method: "GET",
            dataType: "json",
            data: {tal_cal:tal_cal},
            success: function(data){
                var target = $(event.target);
                var next_id = $(that).parent('div').next('div').find('.subcategory'); //assuming you have all your row in #talentcontainer  
                console.log(next_id);

                next_id.empty().html(' ');
                $.each(data, function(key, value) {
                    next_id.append($("<option></option>").attr("value", value).text(value));
                });
                next_id.material_select();
                // $("#talent").html(data);
            }
          });
      });
