I failed asking this as my first question, hope this I do better.
"I just learned the basics of HTML/CSS but have almost to no idea of javascript. And I am making a website where I have a password box with a link button(disabled by default) leading to another page. My struggle is how to make a single password that when entered can enable that button in order to enter the other page. Sorry for my noobish question but am too new in the programming world."
So the html part for what I'm trying to do is:
<div class="whole">
<div>
<input type="password" placeholder="PASSWORD" required id="password" class="pass">
</div>
<div>
<a href="link">
<button class="button" id="button" type="submit" disabled>Click me!!!</button>
</a>
</div>
</div>
And all that I could do by research and on my own with the script was:
<script>
var pass1 = "pass";
var pass2 = document.getElementById("password");
if (pass1 == pass2) {
document.getElementById("button").disabled = false;
}
</script>
Sorry for my clumsiness again!
Thank you!!! :)
<div class="whole">
<div>
<input type="password" placeholder="PASSWORD" required id="password" onkeyup="check()" class="pass">
</div>
<div>
<a href="link">
<button class="button" id="button" type="submit" disabled="true">Click me!!!</button>
</a>
</div>
</div>
<script type="text/javascript">
var pass1 = "pass";
function check(){
var pass2 = document.getElementById("password").value;
if (pass1 == pass2) {
document.getElementById("button").disabled = false;
}
}
I created a fiddle , check it, I hope it will work
https://jsbin.com/qozawoj/edit?html,js,output
<div class="whole">
<div>
<input type="password" placeholder="PASSWORD" required id="password" class="pass" onkeyup="check()">
</div>
<div>
<button class="button" id="button" type="submit" onclick="go()" disabled="true">Click me!!!</button>
</div>
</div>
JS
var pass1 = "pass";
var pass2 = document.getElementById("password");
function check(){
if (pass1 == pass2.value) {
document.getElementById("button").disabled = false;
}
}
function go (){
alert('go');
}
You are close and you need a few more things.
Checkout the code below with // inline comments:
function myCheck(){ // called everytime password is entered
var pass1 = "pass";
var pass2 = document.getElementById("password").value; // you missed "value" !
if (pass1 == pass2) {
document.getElementById("button2").disabled = false; // enable link here
}
}
<div class="whole">
<div>
<input type="password" placeholder="PASSWORD" required id="password" class="pass" onkeyup="myCheck()"> <!-- myCheck() is called everytime the keyboard key goes from down to up -->
</div>
<div>
<a id="button2" href="http://rahul-desai3.github.io/chat/" disabled>button</a> <!-- notice the "disabled" attribute and NO <button> element -->
</div>
</div>
To make the link look like a button, use CSS.

recently started to deal with javascript, now I'm doing a registration page. And at the moment the notification about the incorrect filling of the form is displayed via alert (). How can this be improved so that if you enter incorrectly, you immediately see a hint ?
function valid(form){
var checker = false;
var namePattern = new RegExp("^([A-z]{4,20})$");
var passwordPattern = new RegExp("^[A-z0-9]{4,20}$");
var emailPattern = new RegExp("^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*#[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,5})$");
var fName = form.fName.value;
var lName = form.lName.value;
var password = form.password.value;
var confirmPassword = form.confirmPassword.value;
var email = form.eMail.value;
if(!namePattern.test(fName)){
checker = "Wrong first name";
}else if(!namePattern.test(lName)){
checker = "Wrong last name"
}else if(!passwordPattern.test(password)){
checker = "Wrong password"
}else if(confirmPassword != password){
checker = "Your passwords do not match"
}else if(!emailPattern.test(email)){
checker = "Wrong email"
}
if(checker){
alert(checker);
}
}

I will be grateful for help)
I suggest you put on input elements onchange function, for example:
<input type="text" name="fName" id="fName" placeholder="Your first name" onchange='validateInput(e)'>
And then you check in function:
function validateInput(e){
var namePattern = new RegExp("^([A-z]{4,20})$");
const value = e.target.value;
if(!namePattern.test(value)){
alert("Wrong first name");
// But instead of alert I would suggest you change the color of the input element in order for the user to see real time that he is entering wrong thing.
//When he enters correct data, input border should be green. This is much more user friendly
}
}
You can every validation check separately like this...
function firstname(value){
var checker = false;
var namePattern = new RegExp("^([A-z]{4,20})$");
if(!namePattern.test(value)){
checker = "Wrong first name";
}
if(checker){
alert(checker);
}
}
<input type="text" name="fName" id="fName" placeholder="Your first name" onblur="firstname(this.value)">
I suggest you can use jquery validation.
The thing is, you are checking your form on your submit event (which is obviously the event that is trigger when the form is submitted).
You need to add input validation on each of your input fields via certain event listeners.
If you add onchange event listener, your callback validation will fire each time you move your focus to another element (aka blur event).
If you add oninput event listener, your callback validation will fire each time you type something new.
I would recommend taking a look at the answers of this question.
var checker;
function valid(form){
checker = '';
var namePattern = new RegExp("^([A-z]{4,20})$");
var passwordPattern = new RegExp("^[A-z0-9]{4,20}$");
var emailPattern = new RegExp("^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*#[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,5})$");
var fName = form.fName.value;
var lName = form.lName.value;
var password = form.password.value;
var confirmPassword = form.confirmPassword.value;
var email = form.eMail.value;
if(!namePattern.test(fName)){
checker += "No first name<br/>";
}
if(!namePattern.test(lName)){
checker += "No last name<br/>"
}
if(!passwordPattern.test(password)){
checker += "No password<br/>"
}
if(confirmPassword != password){
checker += "Your passwords do not match<br/>"
}
if(!emailPattern.test(email)){
checker += "No email<br/>"
}
if(checker){
document.getElementById("hint").innerHTML = checker;
}
}
valid(document.getElementById("form"));

Using the oninput event to run every single time a input is changed. More user friendly by displaying a text tip instead of popups, and shows all errors, not just the first one in the if/elseif loop.
P.S: You seem to have forgotten to add the submit button in your code.
EDIT: Also made it check validation as soon as the page loaded up too.
I have been learning javascript by building some mockup website while doing so an error popped up where the form elements are not getting stored to my javascript variables.I have inserted my HTML code of modal dialog box that contains the form and the JS code.Can anyone suggest me where I am going wrong?
document.getElementById("sub").addEventListener("click",store());
function store(){
var userName = document.getElementById("nme").value;
var emailId = document.getElementById("mail").value;
var password = document.getElementById("pd").value;
var rpassword = document.getElementById("rpd").value;
console.log(userName);
if (password !== rpassword){
alert("your password doesn't match");
}
else{
localStorage.setItem("name",userName.value);
localStorage.setItem("email",emailId.value);
localStorage.setItem("password",password.value);
}
}
<div class=row>
<form class="col-xs-12" method="post">
<div class="form-group">
<input type="text" class="form-control form-design input-lg enable" id="nme" name="user" placeholder="UserName">
<input type="text" class="form-control input-lg enable" id="mail" name="mail" placeholder="Email-Id">
</div>
<div class="form-group">

The variables to store should be of type string i.e. var userName should already be a string, so storing userName.value will result in trying to store 'undefined', hence the correct values to store should be the var without the 'value' property and one of your element ids is misspeled i.e.
var rpassword = document.getElementById("rpds").value;
.
e.g. try the following code instead of the current store function
function store(){
var userName = document.getElementById("nme").value;
var emailId = document.getElementById("mail").value;
var password = document.getElementById("pd").value;
var rpassword = document.getElementById("rpds").value;
console.log(userName);
if (password !== rpassword){
alert("your password doesn't match");
}
else{
localStorage.setItem("name",userName);
localStorage.setItem("email",emailId);
localStorage.setItem("password",password);
}
}
You are trying to store userName.value instead of userName (and so on).
Also, you add an event listener but actually call the function store instead of referencing it.
document.getElementById("sub").addEventListener("click",store);
function store(){
var userName = document.getElementById("nme").value;
var emailId = document.getElementById("mail").value;
var password = document.getElementById("pd").value;
var rpassword = document.getElementById("rpd").value;
console.log(userName);
if (password !== rpassword){
alert("your password doesn't match");
}
else{
localStorage.setItem("name",userName);
localStorage.setItem("email",emailId);
localStorage.setItem("password",password);
}
}
I am using regex to disable registering with a apple email
if (str.match('(#me.com)') || str.match('(#icloud.com)') || str.match('(#mac.com)'))
The code is working fine if I run it with the browser console but I cant get it to work initially, Ive wrapped it in a $(document).ready(function () { .. } as well the blur function just never seems to fire. Here is the code below as well as CodePen
Html
<div class="content">
<form action="<?php echo $action; ?>" method="post" enctype="multipart/form-data" role="form">
<div class="warning email-warning" style="display:none;">A non-Apple email address is required due to issues with our mail server. Sorry about that!</div>
<input type="text" name="email" placeholder="" value="" id="Email"/>
<input type="password" name="password" placeholder="Password" value="" />
<input style="font-size: 1.5rem;" type="submit" value="Login" class="btn btn-default" />
<div class="already">Don't have an account? Register</div>
<a class="block text-center" href="/index.php?route=account/forgotten">Forgot your password?</a>
</form>
</div>
JS
function emailValidate(){
var str = $('#Email').val();
$('#Email').blur(function() {
if (str.match('(#me.com)') || str.match('(#icloud.com)') || str.match('(#mac.com)')) {
$('.email-warning').css('display', 'block')
}
});
}
emailValidate()
You need to re-assign the value using val() to variable str inside blur event callback.
function emailValidate(){
$('#Email').blur(function() {
var str = $(this).val();
if (str.match('(#me.com)') || str.match('(#icloud.com)') || str.match('(#mac.com)')) {
$('.email-warning').css('display', 'block')
}
alert(str)
});
}
emailValidate()
you must get value of target object #Email when the blur event trigger. In your code, you get that value when you bind blur event.
Try with
function emailValidate(){
$('#Email').blur(function() {
var str = $('#Email').val();
if (str.match('(#me.com)') || str.match('(#icloud.com)') || str.match('(#mac.com)')) {
$('.email-warning').css('display', 'block')
}
});
}
emailValidate();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="content">
<form role="form">
<div class="warning email-warning" style="display:none;">A non-Apple email address is required due to issues with our mail server. Sorry about that!</div>
<input type="text" name="email" placeholder="" value="" id="Email"/>
<input type="password" name="password" placeholder="Password" value="" />
<input style="font-size: 1.5rem;" type="submit" value="Login" class="btn btn-default" />
<div class="already">Don't have an account? Register</div>
<a class="block text-center" href="/index.php?route=account/forgotten">Forgot your password?</a>
</form>
</div>
Hope this helps.

I am creating a form where a user has to fill out several fields and then click sign up. However, I want JavaScript to check if the passwords match, and if they don't or a field is left empty to put the signup button into a disabled state with Bootstrap. However, nothing is working. Here is my code:
JSFIDDLE: http://jsfiddle.net/jbe65/
echo '
<h3>Don\'t have an account yet? Sign up now!</h3>
<form action="signup.php" method="post">
<input type="text" class="form-control" placeholder="Email" name="email" id="email">
<input type="password" class="form-control" placeholder="Password" name="pass" id="pass">
<input type="password" class="form-control" placeholder="Again" name="passver" id="passver">
<br><br>
<p id="submit">button class="btn btn-primary btn-block" type="submit">Sign Up/button></p>
</form>
<script>
var empty = "";
var email = $(\'#email\').val()\;
var pass = $(\'#pass\').val()\;
var passver = $(\'#passver\').val()\;
if (empty == email)
{
if (pass != passver)
{
document.getElementById("submit").innerHTML=\'<button class="btn btn-primary btn-block" type="submit" disabled="disabled">Sign Up</button>\';
}
}
</script>
';
I will suggest make the button lookalike disable (by css) and once all the cond pass can make it enable (by css)..
$(document).ready(function () {
$("#formid").on("submit", function (e) {
var empty = "";
var email = $('#email').val();
var pass = $('#pass').val();
var passver = $('#passver').val();
if (empty == email || pass !== passver)
{
alert("please enter valid email and password.");
e.preventDefault();
}
else
{
//u can call this in textbox blur also...
$("#sub").removeClass("disable");
}
});
});

I'm assuming you are using PHP. If so, you can replace the echo statement with a closing PHP bracket ?> to escape the parser. It's generally easier to deal with.
To answer the question at hand, since you are using jQuery, there is no need to change the innerHTML of the p tag, just use the .prop() function, like so:
?>
<h3>Don't have an account yet? Sign up now!</h3>
<form action="signup.php" method="post">
<input type="text" class="form-control" placeholder="Email" name="email" id="email">
<input type="password" class="form-control" placeholder="Password" name="pass" id="pass">
<input type="password" class="form-control" placeholder="Again" name="passver" id="passver">
<p id="submit"><button class="btn btn-primary btn-block" type="submit">Sign Up</button></p>
</form>
<script>
var email = $('#email').val();
var pass = $('#pass').val();
var passver = $('#passver').val();
if ("" == email)
{
if (pass != passver)
{
$('#submit button').prop('disabled', true);
}
}
</script>

If you're using HTML5 , Put "Required" and then the submit button will not be loaded if there is an empty field Ex :
Can I have yout help pleas there,I make a validation field for a popup form :
function prepareEventHandlers() {
document.getElementById("contact").onsubmit = function () {
if (document.getElementById("message").value == '') {
document.getElementById("errorMessage").innerHTML = 'the field should not be empty!';
return false;
}
else {
document.getElementById("errorMessage").innerHTML = '';
return true;
}
};
}
window.onload = function () {
prepareEventHandlers();
}
then the html code :
<div id="form-content" class="modal hide fade in" style="display: none;">
<div class="modal-body">
<form class="contact" name="contact" >
<label class="label" for="message">Enter a Message</label><br>
<textarea id="message" name="message" class="input-xlarge"></textarea>
<p><span id="errorMessage"></span></p>
</form>
</div>
<div class="modal-footer">
<input class="btn btn-success" type="submit" value="Send!" id="btnsubmit">
No!
</div>
and I got this error :
TypeError: document.getElementById(...) is null document.getElementById("contact").onsubmit = function () {
Any Idea?
Edit:
OK I add id="contact" to my form so the error is gone but now the popup form is displyaed but when I try to click send with empty or not empty value nothing is happened...
just close </form> after <input class="btn btn-success" type="submit" value="Send!" id="btnsubmit">
and change html form id to contact
