Javascript – How to pass variable from my JS file to Spring Boot Controller?

below is the code for selection of State and City in my view page( I am using thymeleaf 3)

<div class="col-md-2">
                    <label for="inputCity" class="form-label">State</label> <select
                        onchange="print_city('state', this.selectedIndex);" id="sts"
                        name="stt"  class="form-control" required>
                        </select>
                </div>
                <div class="col-md-2">
                    <label for="inputCity" class="form-label">City</label> <select
                        id="state" class="form-control" required>
                        <option  >Select
                            State First</option>
                    </select>
                    <script language="javascript">
                        print_state("sts");
                    </script>
                </div>

I wish to pass the value of the selected State and City to my controller in my Spring boot App, I am unable to do so, However I created this function and it helps me get the value

function getValues() {
    var stateValue = document.getElementById('sts').value;
    var cityValue = document.getElementById('state').value;

    alert(stateValue);
    alert(cityValue);
}

But I am unable to pass this to my springboot MVC controller, I have tried using @RequestParam("stateValue") String stateValue, but it does not work.. I am at my wit’s end please help me guys!!!
