HTML Old School

HTML forms are used for entering data and passing to the scripts (PHP, CGI, ASP, JS, ...).

<form action="script.js" method="POST" enctype="application/x-www-form-urlencoded">
    
    <input type="hidden" name="field1" value="val1">

    <label for="f1">username:</label>
    <input type="text" id="f1" name="username" value="">

    <br>

    <input type="password" id="f2" name="password" value="">

    <br>
