Get the height of the hidden element in jQuery

Last Updated : 06 Nov, 2019

An HTML element can be hidden with the help of .hide() jQuery function or we can hide easily by making visibility equals hidden in CSS. We can easily find the height of this hidden element in jQuery.
There are two kinds of height that are defined with the every HTML element i.e, innerHeight and the outerHeight of the element:

innerHeight: This height is considered when the width of the border is not considered for the selected element.
outerHeight: This height is considered when the width of the border is considered for the selected element.

Example-1: This example show how to calculate innerHeight of the hidden element.

<!DOCTYPE html> 
<html> 
  
<head> 
    <script src= 
"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"> 
  </script> 
    
    <script> 
        $(document).ready(function() { 
            $("#btn1").click(function() { 
                var demo = $("div").innerHeight(); 
                $("#demo").text(demo); 
            }); 
        }); 
    </script> 
    
    <style> 
        div { 
            width: 310px; 
            height: 80px; 
            font-weight: bold; 
            color: green; 
            font-size: 25px; 
            border: 1px solid green; 
            visibility: hidden; 
        } 
          
        body { 
            border: 1px solid green; 
            padding: 10px; 
            width: 300px; 
        } 
    </style> 
</head> 
  
<body> 
    <div> 
  
    </div> 
  
    <p id="demo"> 
      Here the height of the  
      hidden "div" element will appear. 
  </p> 
  
    <button id="btn1">Submit</button> 
  
</body> 
  
</html>
