当我从“请求编号”下拉列表中选择一个选项时，如何将值设置为数据库中的customerNumber（Marketing表中的字段）？

<div class="col-sm-2">
    <label class="label" for="request_id">Request Number:</label>
    <select class="form-control option" id="request_id">
        <option >0 - Request Number</option>
        @foreach ($customer_requests as $customer_request)
            <option value={{$customer_request->id}}>{{$customer_request->id}} -{{$customer_request->requestNumber}} </option>
        @endforeach
    </select>
</div>

<div class="col-sm-2">
    <label class="label" for="customerNumber" >Customer Number:</label>
    <input type="text" class="form-control text" id="customerNumber" name="customerNumber">
</div>

我是一个laravel的学习者，我想知道jQuery是否应该使用？如何使用？

<script>
    $("#request_id").on({
        click: function() {
        }, keypress: function() {
            $( this ).addClass( "inside" );
            var val = $(this).val();
            var data = Marketing::find(val);
            $("#customerNumber").attr("value", data[customerNumber] );

        }
    });

</script>
