如何快速确定给定邮政编码的状态? [英] How can I quickly determine the State for a given zipcode?
问题描述
我不需要城市或地址，只需要州.而且，如果可能的话，我也不想进行API调用.优先级是轻量级的解决方案，最好是Javascript.
I don't need the city or address, just the state. And I don't want to make an API call if possible. The priority is a light-weight solution, ideally just Javascript.
我有一个用户输入zipcode，并且我想根据邮政编码所在的状态显示一段文本.我知道查找城市和州要复杂得多，因此，USPS公开的API可能是最好的.但是，为了仅与状态匹配(也许仅针对前三个数字)，解决方案(我认为)应该简单，轻便.
I have a user-input zipcode, and I want to display a paragraph of text depending on the state that the zipcode is in. I know it's much more complicated to lookup City and State, and for that an API such as the one the USPS exposes is probably best. But to just match state, perhaps on just the first three numbers, the solution (I think) should be easy and lightweight.
理想情况下使用Javascript. PHP也可以工作.
Javascript ideally. PHP could also work.
推荐答案
美国邮政编码数据实际上足够稳定，即使只有State(不需要城市或其他).
US zipcode data is in fact stable enough that you can do this without hitting an API or a database if only State (not the City or anything else) is needed.
这是一个轻量级的JS解决方案，它确定状态并将其返回为两个字母的邮政缩写.
Here's a lightweight JS solution that determines the state and returns it as its two-letter postal abbreviation.
function getState(zipcode) {
// Ensure param is a string to prevent unpredictable parsing results
if (typeof zipcode !== 'string') {
console.log('Must pass the zipcode as a string.');
return;
}
// Ensure we have exactly 5 characters to parse
if (zipcode.length !== 5) {
console.log('Must pass a 5-digit zipcode.');
return;
}
// Ensure we don't parse strings starting with 0 as octal values
const thiszip = parseInt(zipcode, 10);
const st;
const state;
// Code blocks alphabetized by state

您可以返回州的全名，方法是在最后一行返回state而不是st.
You can return the state's full name instead by returning state instead of st on the last line.
