# is-valid-id-card
一个校验身份证号是否符合规则的方法。(A function to test if a Chinese ID card number is valid.)   
校验规则有点复杂，但是代码写的尽量简洁。代码中用到了Array的reduce和map方法，使用时需要浏览器支持这些方法。   
参考国家标准:[GB 11643-1999](http://www.gb688.cn/bzgk/gb/newGbInfo?hcno=080D6FBF2BB468F9007657F26D60013E)，只有18位身份证才符合标准   
参考了此文章：https://blog.csdn.net/qq_41589580/article/details/81040772   
暂时未做每月不同天数及闰年的校验，如生日是2月31号也返回true。今后有空可能会加上此校验。    
注意：身份证号符合规则，只是该身份证号符合国家标准中的规则，并不意味着该身份证号真实存在。

## Installation
```
npm install is-valid-id-card --save   
也可以直接复制index.js中的方法定义，粘贴到需要的地方直接使用   
```

## Examples
```
const isValidIDCard = require('is-valid-id-card')
console.log(isValidIDCard('')) // false
console.log(isValidIDCard('123456')) // false 
console.log(isValidIDCard('11012119880808223x')) // true
```
