To get next / previous element using JavaScript, we can use the nextSibling and previousSibling properties.
For instance, we write
<div id="foo1"></div>
<div id="foo2"></div>
<div id="foo3"></div>
to add 3 divs.
Then we write
document.getElementById("foo2").nextSibling;
document.getElementById("foo2").previousSibling;
to get the next and previous sibling of the div with ID foo2 with nextSibling and previousSibling.
Conclusion
To get next / previous element using JavaScript, we can use the nextSibling and previousSibling properties.
