I have been trying to figure out a way to send emails with JavaScript. So the first thing I did was went to Google and looked up if this is possible. I found out you can use the code below to send JavaScript emails.
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8"/>
</head>
<body>
<form method="post">
<input type="text" id="emailSubject" placeholder="Type your
subject... "/>
<input type="text" id="emailBody" placeholder="Type something... "/>
<button onclick="send()">
Send
</button>
</form>
</body>
<script type="text/javascript" src="https://smtpjs.com/v3/smtp.js"></script>
<script type="text/javascript" src="script.js"></script>
</html>
script.js
const emailSubject = document.getElementById("emailSubject").value;
const emailBody = document.getElementById("emailBody").value;
function send() {
Email.send({
Host: "smtp.gmail.com",
Username: "myemail#gmail.com",
Password: "*******",
To: "anotheremail#gmail.com",
From: "myemail#gmail.com",
Subject: emailSubject,
Body: emailBody,
}).then(
message => alert("Sent successfully.")
);
}
Why didn't this work? I check this code for any misspelled words, and found none. So can anyone help with this?
Looking at the tutorial there is a key difference between your implementation and the one provided. Where you are using <button> the example uses <input type="button"> like below:
<input type="button" value="Send Email" onclick="send()"/>
Key difference is the button you are using is submitting the form element and refreshing the page so the send() function is never run.
With the above in place of the button the form is never submitted and the function is called.

I have one simple html page with a text field that asks for user's name. i want to save what user enter and on another page i want to retrieve that name and say hello + (user's name).
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>LocalStorage</title>
</head>
<body>
<form>
<p>Enter your name</p>
<input type="text">
<button type="submit" value="submit">Submit</button>
</form>
</body>
</html>
and the second page is where the data from first page comes (through localStorage).
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>secondPage</title>
</head>
<body>
<h1>Hello </h1>
</body>
</html>
thank you.
I'm not sure if this is a homework assignment but this should get you started.
It will involve:
First storing the data into localStorage
Then directing the user over to the second page - most likely through window.location.href.
Then pulling the data back out of localStorage to display there.
Here's a jsfiddle to get you started setting and getting data.
https://jsfiddle.net/em92zbod/
The two main functions are:
window.localStorage.setItem("key", "value");
window.localStorage.getItem("key");
Where "key" is any identifier you want to use for the value.
Here's a suggested approach by using sessionStorage.
However, you can also use localStorage with the same implementation method. The only differences between them is localStorage will keep the data even if you close your browser. Which in this case, saving userName I think it's better to use sessionStorage.
1.html
<form action="2.html" onsubmit="callme()">
<p>Enter your name</p>
<input id="tbName" type="text">
<button type="submit" value="submit">Submit</button>
</form>
<script>
function callme(){
var name = document.getElementById('tbName').value;
sessionStorage.setItem('userName', name);
}
</script>
2.html
<h1 id="welcome"> </h1>
<script>
window.onload = function() {
document.getElementById('welcome').innerText = "Hello, " + sessionStorage.getItem('userName');
};
</script>
Code update
page 1
window.addEventListener("DOMContentLoaded", () => {
document.getElementById("myForm").addEventListener("submit", e => {
const form = e.target;
const name = document.getElementById('tbName').value;
sessionStorage.setItem('userName', name);
})
})
<form action="2.html" id="myForm">
<p>Enter your name</p>
<input id="tbName" type="text">
<button type="submit">Submit</button>
</form>
Page 2
window.addEventListener("DOMContentLoaded", () => {
document.getElementById('welcome').textContent = `Welcome ${ sessionStorage.getItem('userName') || "stranger"}`;
})
<h1 id="welcome"></h1>
This is fairly simple, I'm trying to make the login button work, and redirect to a different file (placeholder.html) if what is in the email and password match the following:
Login: Admin
Password: Password123
I have yet to get the login button to work in the first place to redirect, and id like to keep it as a button element by using, the 'onlick=' with a function in js or an id for now.
Thank you so much for the help :)
Apologies if this is a little sloppy, one of my first times asking for help here haha
Here is what I had so far, which dent work fully:
<!DOCTYPE html>
<html>
<head>
<title>Login page</title>
<link href="style." rel="stylesheet" type="text/css" />
<script src="script.js"></script>
</head>
<body>
<div class="login-page">
<div name="login" class="form">
<div class="title login" style="font-size: 25px; font-family: Roboto; padding-bottom: 25px;">
Login Form
</div>
<form class="login-form" action="login.php" method="post">
<input type="email_" placeholder="email"/>
<input type="password" placeholder="password"/>
<button id="login_button">login</button>
<p class="message" style="font-family: Roboto, sans-serif;">Not registered?
Create an account
</p>
</form>
</div>
</div>
</body>
<script type="text/javascript">
document.getElementById("login_button").onclick = function () {
location.href = "#placeholder";
};
</script>
</html>
Welcome to StackOverflow, there are a few things that I wanted to cover here as part of the answer.
The function is running onClick, the way you're using location.href is invalid though. You are redirecting to an anchor (it starts with a #), The way this is implemented in browsers is that it will redirect your scroll positioning to the top of the element with ID, if you had an element on your page with the ID of placeholder (and the page height was more than 100%) it would move the scroll position of the page, not redirect.
I believe you're looking for
location.href = "placeholder.html";
You wanted the user to be redirected based on the username and password that they enter, I will provide the solution below but before that, I wanted to say that this isn't secure, the username and password are visible inside the source code and if you planned to use this to hide important information it will not work because the code is visible to anyone who accesses the webpage, you should be using a server-side language such as NodeJS or PHP to hide that information, I assume that this is just for practise/learning though.
The first thing you'll want to do is get the username and password.
Your <input type="email_" placeholder="email"/> should be <input type="text" placeholder="email"/>. For some reason you put the type as what looks to be a typo email_ and not email but since you said the username was admin that is just text.
I would start by giving an ID to both the username and password elements.
<input type="email" id="username" placeholder="email"/>
<input type="password" id="password" placeholder="password"/>
Then inside your function you can change it to check and redirect like below
document.getElementById("login_button").onclick = function () {
const username = document.getElementById("username").value
const password = document.getElementById("password").value
if (username === 'Admin' && password === 'Password123') {
location.href = "placeholder.html";
}
};
That will also be case-sensitive.
There are a couple of ways that you could do this, here is a simple example:
<!DOCTYPE html>
<html>
<head>
<title>Login page</title>
<link href="style." rel="stylesheet" type="text/css" />
<script src="script.js"></script>
</head>
<body>
<div class="login-page">
<div name="login" class="form">
<div class="title login" style="font-size: 25px; font-family: Roboto; padding-bottom: 25px;">
Login Form
</div>
<form class="login-form" action="login.php" method="post">
<input type="email_" placeholder="email"/>
<input type="password" placeholder="password"/>
<button id="login_button" onclick="login()">login</button>
<p class="message" style="font-family: Roboto, sans-serif;">Not registered?
Create an account
</p>
</form>
</div>
</div>
</body>
<script type="text/javascript">
function login() {
// Login logic here
if (loginSuccesful) {
window.location.href = "/placeholder.html";
}
}
</script>
</html>
First off the bat I am new to this an really trying my best to understand how this works. I have the following simple login form that leads to a homepage if the right login credentials are submitted. However when run in Firefox with JavaScript disabled the login credentials are ignored and my homepage is displayed anyway no matter what login details I provide. I have created a message in between <noscript></noscript> which fires when JavaScript is disabled. What I would like to achieve is that the warning message displays only and that the form etc. is disabled and not displayed until the login page is reloaded with JavaScript enabled. Can someone please help me with this? It is much appreciated!! My code is
<!doctype html>
<!-- This is is the main start page saved in index.html -->
<html lang="en-US">
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<body>
<h2>Login details</h2>
<noscript>
<h3>Before you login</h3>
<p>JavaScript needs to run for this site to work properly.<br />
Please activate JavaScript in your browser<br />
and reload this page to login.
</p>
</noscript>
<form id="myForm" name="login" onsubmit="return validateFormOnSubmit()" action="http://localhost:8080/index.html" method="post">
<fieldset>
<label for="username">Username:</label><br>
<input type="text" id="username" name="username"><br>
<label for="password">Password:</label><br>
<input type="password" id="password" name="password"><br><br>
<input type="submit" value="Submit">
</fieldset>
</form>
</body>
</html>
<script>
function validateFormOnSubmit() {
var un = document.login.username.value;
var pw = document.login.password.value;
var username = "username"
var password = "password"
if ((un == username) && (pw == password)) {
return true;
}
else {
alert ("Login was unsuccessful, please check your username and password");
return false;
}
}
</script>
You can achieve this without adding extra JavaScript. You can use a <noscript> tag also in the <head>, so you are able to hide this with CSS:
…
<head>
…
<noscript>
<style>
#myForm {
display: none
}
</style>
</noscript>
</head>

I have two HTML pages: firstpage.html and secondpage.html. In firstpage.html, there is a form-
firstpage.html:
<!DOCTYPE html>
<html>
<head>
<title>Form Filling</title>
</head>
<body>
<form action="secondpage.html" method="GET">
Enter Serial Number: <input type="number" name="serialNumber" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
The firstpage data is sent to secondpage.html. I want to display and use the form data serialNumber in secondpage.html-
secondpage.html:
<!DOCTYPE html>
<html>
<head>
<title>Display</title>
</head>
<body>
<form name="selva" action="thirdpage.html">
<input type="hidden" name="kumar">
</form>
<script type="text/javascript">
var locate=window.location;
document.selva.kumar.value=locate;
var text=document.selva.kumar.value;
function pass(str)
{
point=str.lastIndexOf('=');
return(str.substring(point+1,str.length));
}
document.write("Serial Number" + pass(text));
</script>
</body>
</html>
So now I can pass the serialNumber variable from firstpage.html to secondpage.html so that the above code in secondpage.html will show the serial nuimber, and I want same serial number in at thirdpage-
thirdpage.html:
<!DOCTYPE html>
<html>
<head>
<title>Repeating</title>
</head>
<body>
<form method="link">
Enter Serial Number2: <input type="number" name="burns" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
please tell how to print a data in all those pages?
The simplest method I could find for this is, write all the three pages in a single html file and display them based on conditions. This way you dont need to use localstorage.
Other method will be to use query parameters. You can simply learn how to use them. Here's the link to simple javascript-handled query params plugin:
http://jillix.github.io/url.js/
You can pass the serial no as a query parameter to another html. If you are confused on how to use this method, let me know and I'll tell you in detail.
I am trying to use jQuery/AJAX to run a PHP file on a server. This PHP simply adds a row with some constants to a database. Here is my code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Submit Application</title>
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript">
function doSomething() {
$.get("http://.../submitApp.php");
}
</script>
</head>
<body>
<form id="form1" name="form1" method="post" action="javascript:doSomething()">
<p>
<label for="programName"></label>
<input type="text" name="programName" id="programName" />
</p>
<p>
<label for="greQuant"></label>
<input type="text" name="greQuant" id="greQuant" />
</p>
<p>
<label for="greVerbal"></label>
<input type="text" name="greVerbal" id="greVerbal" />
</p>
<p>
<input type="submit" name="submitApp" id="submitApp" value="Submit" />
</p>
</form>
</body>
</html>
Upon pressing the submit button on the above form, nothing seems to happen. I should mention I am running this locally via DreamWeaver. I know for a fact that the code is reaching the JavaScript method and that the PHP code is functional. Anyone know what's wrong?
Use POST instead of GET to do this work.
function doSomething() {
var programName = $('#programName').val();
var greQuant = $('#greQuant').val();
var greVerbal = $('#greVerbal').val();
$.ajax({
type: "POST",
url: "submitApp.php", //URL that you call
data: { programName: programName, greQuant:greQuant, greVerbal:greVerbal } //var in post: var from js
}).done(function(msg) {
alert(msg);//change to something to indicate action
}
});
and with your php, handle like this
<?php
$programName = $_POST['programName'];
$greQuant = $_POST['greQuant'];
$greVerbal = $_POST['greVerbal'];
//do something important
?>
this is just a simple example, you need apply some security to this php code
