获取价值

-1

如何从文本中获得价值，当我在按钮点击我的函数可以使用文本框的值这个程序是计算年龄获取价值

function getDate(birth){ 
 
    var now = new Date(); 
 
    var currentYear = now.getFullYear(); 
 
    var currentMonth = now.getMonth(); 
 
    var currentDay = now.getDate(); 
 
    
 
    var birthYear = birth.getFullYear(); 
 
    var birthMonth = birth.getMonth(); 
 
    var birthDay = birth.getDate(); 
 
    
 
    var age = currentYear - birthYear; 
 
    var age_month = currentMonth - birthmonth; 
 
}

<!DOCTYPE html> 
 
<html> 
 
    <head> 
 
     <title>TODO supply a title</title> 
 
     <meta charset="UTF-8"> 
 
     <meta name="viewport" content="width=device-width, initial-scale=1.0"> 
 
     <script src="javascript.js"></script> 
 
    </head> 
 
    <body> 
 
     <form> 
 
      <input type="text"/> 
 
      <input type="button" value="Calc" onclick="getAge()"/> 
 
     </form>

我真的不明白你在问什么，getAge函数在哪里？ –

function getAge(){ 
 
    var text=document.getElementById('myInput').value; 
 
    console.log(text); 
 
    }

<input id="myInput" type="text"/> 
 
<input type="button" value="Calc" onclick="getAge()"/>
