          <option value="WF">Wideroe</option>
      </select>
      <span tabindex="0" id="search_airline-button" role="combobox" aria-expanded="false" aria-autocomplete="list" aria-owns="search_airline-menu" aria-haspopup="true" class="ui-selectmenu-button ui-selectmenu-button-closed ui-corner-all ui-button ui-widget"><span class="ui-selectmenu-icon ui-icon ui-icon-triangle-1-s"></span>
          <span class="ui-selectmenu-text">Flygbolag: Alla</span>
      </span>
 </li>

此外，我在TS中具有使用word生成变量的功能 - ＆＃34; Flygbolag＆＃34;

这是

function update_search_airline() {
    $(".ui-selectmenu-text", $("#search_airline-button")).html(
  __("Flygbolag") + ": " + $(".ui-selectmenu-text", $("#search_airline-button")).html());
}

因此，当我加载页面一切正常时，我得到了例如

但是当我从这个选择中选择值时，我也需要使用这个词

所以在函数中我创建了这段代码

function load_field_actions(): void {
  $(".tooltip").tooltipster()
  $("#search_airline").change(update_search_airline)
}

此行必须正确更新

  

$（＆＃34;＃search_airline＆＃34）。变化（update_search_airline）

但它只是在没有Flygbolag的情况下将默认值更改为下一个值
