How to get next element using JavaScript-only?
Let's say we have this markup: <!DOCTYPE html> <html> <head> <meta charset="utf8" /> <title>project.js</title> <script src="project.js"></script> <script> </script> </head> <body> <h1>some project — javascript & html tests</h1> <hr /> <p> testing 123 </p> </body> </html> I know that there are .prependChild() , .appendChild() , .innerHTML , etc, properties and methods, but what I am looking for is how to add (append) contents after the </body> tag closure? I need this, without using jQuery — is it possible? If you use 'id'.you can use these property: document.getElementById('id').nextSibling;
