如何从文本中获取选定的值？

Answer 1

您必须使用jQuery或javascript来获取并设置选定的值，例如波纹管

var city=$('#city :selected').text();
$('#city_selected').val(city)

 <select id="city">
        <option th:each="city:${cities}"
                th:value="${city.value}"
                th:utext="${city.name}"/>
    </select>

    <div >
    <input id="city_selected"/>
    </div>
