That is unsurprising, as the W3Schools people apparently don't know HTML
themselves.  Avoid this site, it is not suitable as Web development
reference.

What I had to read below is very far from being a "html-file".

`orange' is not a valid value for the deprecated `bgcolor' attribute.

Not Valid, the `p' element must not be contained in the `h1' element.

Not Valid, the `action' attribute is required.

Semantically wrong element, we are not talking paragraphs of text here. 
Use
`div' if you must.

You should set the `size' attribute, too.

You don't want to use XHTML.

See above.

You don't want to submit this form's information, so you don't need a form
element here.

As for your question, you can achieve optional client-side operation with

  <form action="..." onsubmit="return handleSubmit(this)">
    <script type="text/javascript">
      function handleSubmit()
      {
        ...

        // if successful
        return false;
      }
    </script>
  </form>

But I strongly suggest you learn HTML first.
