如何从国际电话输入中获取国家/地区价值？

Question

所以我是 javascript 的新手。我想创建有两个字段的表单，电话号码和国家。我想在我的数据库中将它们分开。我想知道如何从 intl-tel-input (https://github.com/jackocnr/intl-tel-input) 中获取国家/地区价值。 例如 HTML

                      <form>
                        <label>Phone Number</label>
                        <!-- using intl-tel-input -->
                        <input type="tel" name="phone">

                        <label>Country</label>
                        <!-- how can i get country value automatically here from phone number field? -->
                        <input type="text" name="country">
                      </form>

谁能帮我解决这个问题？提前致谢。
