Question

I'm new to HTML and developing and login form. Please find below the code I used. I want to import my JavaScript code into HTML form.please help me.

C:\Program Files\xampp\htdocs\forsiteSystem\thems\js\validation.js

 function validateForm()
{
var x=document.forms["login"]["email"].value;
if (x==null || x=="")
  {
  alert("Email must be filled out");

C:\Program Files\xampp\htdocs\forsiteSystem\thems\login.html

<html>
        <head>
            <title>Login form</title>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
            <script src="js/validation.js">
            </script>
        </head>
        <body>
            <div>
                <form name="login" action="" method="post" onsubmit="return validateForm()">
                    Email: <input type="text" name="email"><br>
                    password: <input type="text" name="pass"><br>
                    <input type="submit"  id="Submit_button" >
                </form>
            </div>
        </body>
    </html>

In login.html, you're not closing the meta tag, is that normal? — Soma

Include your js file properly like this:

<script src="js/validation.js">

This code works for me.try

<html>
        <head>
            <title>Login form</title>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
            <script src="js/builder.js">
            </script>
        </head>
        <body>
            <div>
                <form name="login" action="" method="post" onsubmit="return validateForm()">
                    Email: <input type="text" name="email"><br>
                    password: <input type="text" name="pass"><br>
                    <input type="submit"  id="Submit_button" >
                </form>
            </div>
        </body>
    </html>

Your js file will be on same directory under js file with this name builder.js. Code in js file is :

function validateForm()
{
var x=document.forms["login"]["email"].value;
if (x==null || x=="")
  {
  alert("Email must be filled out");
  return false;
  }
}
