export default validateIdent.IdentityCodeValid   //导出

使用方法

import IdentityCodeValid from '@/utils/checkIdent'
let ident = '42118199902106320' //假身份证
let data = ident.toUpperCase() //转换成大写
IdentityCodeValid( data )//得到 false
 
let realData = '420102199003078776' //真身份证
let data1 =  realData .toUpperCase() 
IdentityCodeValid( data1 ) //得到true
