The previousElementSibling property in HTML DOM is used to return the previous element of the same level as the given element. If no previous element is found on the same level then it returns null. It is a read-only property. It is similar to the previousSibling property but the difference is previousSibling property returns the previous sibling node as an element node, a text node, or a comment node, while the previousElementSibling property returns the previous sibling as an element node. 

Syntax:

node.previousElementSibling

Return value: This property returns a previous sibling of the specified element or null if the current element has no previous sibling. 

Example: In this example, we will use the previousElementSibling property.

html

<!DOCTYPE html>
<html>
 
<head>
    <title>
        HTML DOM previousElementSibling Property
    </title>
</head>
   
<body>
    <h2>
        DOM previousElementSibling Property
    </h2>
    <h4 id="h42">Web Languages:</h4>
    <select size="4">
        <option>HTML</option>
        <option>CSS</option>
        <option>JavaScript</option>
        <option id="Select">XML</option>
    </select>
    <br><br>
    <button onclick="Geeks()">
        Previous Element Sibling
    </button>
    <br><br>
    <p id="p"></p>
    <script>
        function Geeks() {
            let a = document.getElementById("Select")
                    .previousElementSibling;
                    document.getElementById("p").innerHTML
                          = a.text;
        }
    </script>
</body>
   
</html>

                    

Output: 

 

Note: Don’t use white space between two sibling elements, otherwise, the result will be “undefined”.
