试图在JavaScript中使用PHP

Question

我使用php，因为我使用的java代码对我来说很难从数据库中检索信息并将它们添加到下拉列表中。我使用下面的函数检索它们，但我不知道如何将检索到的数据添加到下拉列表中。私人清单listOfTeams;

public void returnTeamListfromDB() {
    listOfTeams = new ArrayList<DepartmentBean>();
    Connection connection = DB.getCon();

    try {
        Statement statement = connection.createStatement();

        /* select from the databse but in an ascending order ASC */
        ResultSet result = statement.executeQuery("select department_id from departments order by department_id ASC");

        while (result.next()) {
            DepartmentBean department = new DepartmentBean();
            String nameFromDB = result.getString("department_id");
            int oya = Integer.parseInt(nameFromDB);
            department.setId(oya);

            /* add object to in the team list */
            listOfTeams.add(department);

        }
        connection.close();
    } 
    catch (SQLException e) 
    {
        // TODO Auto-generated catch block
        e.printStackTrace();

    }
}
