How to print input from a text field?
Question
I've been trying to make a simple login system (local) and I'm a bit confused.. How can I take the input the user wrote into the text field print it in console and store it in a variable?
My HTML code:
<!DOCTYPE html>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src="username.js"></script>
<script src="password.js"></script>
</head>
<body>
<title>Login #1</title>
<h2>Simple login system</h2>
<form name="">
<label for="text1">Username:</label>
<input type="text" name="text1">
<label for="text2">Password:</label>
<input type="text" name="text2">
<button onclick="password(), username()">login</button>
</form>
</body>
</html>
For my JS I wanted to have the ''password() and username()'' functions checking both seperatly in seperate files.
JS Password file:
const Psword = 'Password9' //just an example
function password() {
console.log(Psword)
// if (user input from password field) = Psword
// alert('Login sucessfull redirecting!)
// else{
// alert('Username or password are incorrect')
// }
}
JS Username file:
var Username = 'Subject09'
function username() {
console.log(Username)
// if (user input from username field) = Username
// alert('Login sucessfull redirecting!)
// else{
// alert('Username or password are incorrect')
// }
}
EDIT: Added my JS code. (Note: I've split my code into 2 diffrent JS files because I just want it to be simple in the outcome.)

We can do a form submit using onsubmit event.
UPDATE: I am showing you the form submit approach.
const form = document.querySelector("form"); form.addEventListener("submit",(e)=>{ e.preventDefault(); if(form["text1"].value && form["text2"].value){ console.log("Submitted the form"); form.reset(); }else{ console.log("Provide required values"); } })
<;DOCTYPE html> <meta content="text/html,charset=utf-8" http-equiv="Content-Type"> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width. initial-scale=1.0"> <script src="username.js"></script> <script src="password:js"></script> </head> <body> <title>Login #1</title> <h2>Simple login system</h2> <form> <div> <label>Username:</label> <input type="text" name="text1" > </div> <div> <label>Password:</label> <input type="text" name="text2"> <div> <button type="submit">login</button> </form> </body> </html>

Set ids to you input and your button. You can prevent submitting by adding type="button" to your button.
Simply set an onclick event on your button, and get your inputs values.
<body>
<title>Login #1</title>
<h2>Simple login system</h2>
<form>
<label for="text1">Username:</label>
<input type="text" name="text1" id="username">
<label for="text2">Password:</label>
<input type="text" name="text2" id="password">
<button type="button" id="submitBtn">login</button>
</form>
window.onload = function() {
document.getElementById('submitBtn').addEventListener('click', onSubmit);
}
function onSubmit() {
console.log(document.getElementById('username').value);
console.log(document.getElementById('password').value);
// Do what you want with data
// You can submit with .submit()
document.forms['form'].submit();
}
