Calculate the date of birth age and gender (18) according to the id card number and calculate the length of service according to the entry time

This applies to the management of these files in the OA project

1. Calculate the date of birth, age and gender (18 digits) according to the id card number

 
// Get input id number  
var UUserCard = $("#UUserCard").val(); 
// Get the date of birth  
//UUserCard.substring(6, 10) + "-" + UUserCard.substring(10, 12) + "-" + UUserCard.substring(12, 14); 
// For gender  
if (parseInt(UUserCard.substr(16, 1)) % 2 == 1) { 
// male  
} else { 
// female  
} 
// For age  
var myDate = new Date(); 
var month = myDate.getMonth() + 1; 
var day = myDate.getDate(); 

var age = myDate.getFullYear() - UUserCard.substring(6, 10) - 1; 
if (UUserCard.substring(10, 12) < month || UUserCard.substring(10, 12) == month && UUserCard.substring(12, 14) <= day) { 
age++; 
} 
// age  age 

2. Calculate the length of service according to the entry time

 
// Gets the input entry time converted to Date 
var UToTime = $("#UToTime").val(); 
var aDate = UToTime.split("-"); 
// Because of the month 0-11 So let's subtract the input month 1 
var NewDate = new Date(aDate[0], aDate[1] - 1, aDate[2]); 
// The current time  
var myDate = new Date(); 
// You subtract the time to get the value of milliseconds  
var dif = myDate.getTime() - NewDate.getTime(); 
myDate.setTime(dif); 
// The results for" 1 years 5 month 29 Day 】 this  
//myDate.getFullYear() - 1970 + " years " + myDate.getMonth() + " month " + myDate.getDate() + " day "
