How to solved always looping select option value from ajax

Time:09-16

I have a data, when I update the data (using modal), select option work correctly enter image description here

When I close the modal, and I click the edit button again, something wrong with select option: enter image description here

This is my edit modal ajax:

// Function for edit modal plan schedule
    $('body').on('click', '.editPlanSchedule', function() {
        var Item_id = $(this).data('id');
        $.get("/quotation/getEditPlanSchedule"   '/'   Item_id, function(data) {
            console.log(data['product_plan']);
            $('.modal-title-edit').html("Edit Plan Schedule Item");
            $('#saveBtn').val("Update");
            $('#updatePlanSchedule').modal('show');
            $('#id').val(data['data'].id);
            $('#qno').val(data['data'].qno);
            $('#b_amount').val(data['data'].b_amount);
            // $('#product_plan_edit').val(data.product_plan);
            
            data['product_plan'].forEach(function(item, index) {
                
                $('#product_plan_edit').append($('<option>', {
                    id: item.id,
                    value: item.productplanID,
                    text: item.productplanID
                }));
                
                if(data['data'].product_plan == item.productplanID){
                    $('#' item.id).attr('selected',true);
                }
            });

        })
    });

This is the method from controller:

public function getEditPlanSchedule($id)
{
    $item['data'] = QuotationPlanSchedule::find($id);
    $item['product_plan'] = ProductPlan::orderby('id', 'asc')->get();
    return response()->json($item);
}

CodePudding user response:

You have to clear all options before adding again:

$("#product_plan_edit").empty();

CodePudding user response:

Either .empty the container or don't use append (better for the DOM update)

I am a little confused about your use of data['data'].product_plan to test the ID. In any case you can see the principle

$('#product_plan_edit').html(
  data['product_plan'].map(item => `<option value="${item.productplanID}">${item.productplanID}</option>`).join('')
);
$('#product_plan_edit').val(data['data'].product_plan); // select item.productplanID === data['data'].product_plan
