步骤

1. 从下拉列表中选择一个国家.
2. 城市下拉列表将自动填充所选国家/地区的城市列表.
3. 如果该国家/地区可以使用州/省，则该州的列表将与该国的所有州/州列表一起显示.

然后，我需要验证所选的城市，州和国家/地区.

Then I need to validate the selected city, state and country.

你有什么主意吗?

预先感谢

推荐答案

如果您想让外国人更容易输入地址，则请只需提供一个文本字段，即可在其中输入地址输入为格式化文本.很少有国家使用州(或类似名称)作为地址的一部分，我不明白为什么要提供城市的下拉列表.德国城市列表(或邮政地址中更正确，有效的地名)将包含大约23,000个条目.您认为更简单的方法是，输入地址或尝试在这样的列表中找到地名_

If you want to make it easy for foreigners to enter an address, then please simply offer a text field, where the address can be entered as formatted text. Very few countries are using a state (or something similar) as part of the address and I don't understand why you want to offer a drop-down list with cities. A list of German cities (or more correct, valid place names in a postal address) would contain some 23,000 entries. What do you think is more easy, enter the address or try to find the place name in such a list_
