Here John discussed about Login form Validation in javascript.
Java Script is dynamic and most commonly used in all programming languages.
Java Script code should be enclosed with in Script Tags
Ex :

<script type="text/javascript"></script>


<script language = "JavaScript">
        function validate() {
            var username = document.getElementById("username").value;
            var password = document.getElementById("password").value;
            if (username == null || username == "") {
                alert("Please enter the username.");
                return false;
            if (password == null || password == "") {
                alert("Please enter the password.");
                return false;
            alert('Login successful');


<form id="form1" runat="server">
    <div class="container">
        <div class="main">
                Javascript Login Form Validation</h2>
            <form id="form_id" method="post" name="myform">
                User Name :</label>
            <input type="text" name="username" id="username" />
                Password :</label>
            <input type="password" name="password" id="password" />
            <input type="button" value="Login" id="submit" onclick="validate();" />
