Height in jQuery

Height is the vertical measurement of the container, for example, height of a div. It excludes the padding border and margin.

To get the height of an element in jQuery, use the height() method in jQuery.

Example

You can try to run the following code to get the height:

Live Demo

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $("button").click(function(){
        alert("Height of div element: " + $("div").height());
    });
});
</script>
</head>
<body>

<div style="height:300px;width:450px;padding:20px;margin:1px;border:1px solid red; background-color:gray;"></div><br>

<button>Get Height of div</button>

</body>
</html>

innerHeight in jQuery

The innerHeight( ) method gets the inner height (excludes the border and includes the padding) for the first matched element.

Example

You can try to run the following code to learn how to work with innerHeight in jQuery:

<html>

   <head>
      <title> jQuery innerHeight()</title>
      <script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
       
      <script>
         $(document).ready(function() {
           
            $("div").click(function () {
               var color = $(this).css("background-color");
               var height = $(this).innerHeight();
               $("#result").html("Inner Height is <span>" +
                  height + "</span>.");
               $("#result").css({'color': color, 'background-color':'gray'});
               $("#result").height( height );
            });    
         });
      </script>
       
      <style>
         #div1{
             margin:10px;
             padding:12px;
             border:2px solid #666;
             width:60px;
         }
         #div2 {
             margin:15px;
             padding:5px;
             border:5px solid #666;
             width:60px;
         }
         #div3 {
             margin:20px;
             padding:4px;
             border:4px solid #666;
             width:60px;
         }
         #div4 {
             margin:5px;
             padding:3px;
             border:3px solid #666;
             width:60px;
         }
      </style>
   </head>
   
   <body>
   
      <p>Click on any square:</p>
      <span id = "result"> </span>
       
      <div id = "div1" style = "background-color:blue;"></div>
      <div id = "div2" style = "background-color:pink;"></div>
      <div id = "div3" style = "background-color:#123456;"></div>
