redirect event with javascript

I'm doing a project and I don't understand the front end well.
I have this html page:
<form class="form-group" action="/create" method="post" enctype="multipart/form-data">
<div class="title">
<h1>Cadastre seu produto</h1>
</div>
<div class="single-input">
<input class="form-control" placeholder="nome do produto" type="text" id="nome_produto" name="nome_produto">
</div>
<div class="single-input">
<input class="form-control" placeholder="quantidade em estoque" type="number" id="quantidade" name="quantidade">
</div>
<div class="single-input">
<input class="form-control" placeholder="preco do produto" type="number" id="preco_produto" name="preco_produto">
</div>
<button onclick="loadPage()" id="button" type="submit" class="btn btn btn-danger">ENVIAR</button>
</form>
I want that when I click on the SUBMIT button, I am redirected to another page, I want to do this using Javascript.
I tried to do this:
<script type="text/javascript">
function loadPage(){
window.location("http://localhost:8080/list")
}
but it's not working, every time I click on the button I'm redirected to a blank page
Any solution ?

Window.location is a property not a function. So it should be
window.location = "http://localhost:8080/list";

How to write a js script that verifies input on html

I am trying to add validation to a html form that looks like this:
<div id="container">
<header>
<h1>Production Form</h1>
</header>
</br>
<div class="content">
<div class="row">
<article class="col-xs-12">
<form id="cf-task-form">
<section>
<br><br>
<div class="row form-group">
<div class="col-xs-3">
<label for="link">Link</label>
<input type="url" id="link" class="form-control" name="output[link]">
</div>
<div class="col-xs-3">
<label for="address">Address</label>
<input id="address" class="form-control" name="output[address]">
</div>
<div class="col-xs-3">
<label for="research">Research</label>
<select id="research" name="output[research]">
<option value="0">0</option>
<option value="1">1</option>
</select>
</div>
</section>
<div class="col-xs-offset-6 col-xs-6">
<input type="button" class="btn sub-btn pull-right" id="submit-btn" value="Submit" tabindex="10">
</div>
</form>
</article>
</div>
<div class="clear"></div>
</div>
</div>
However the code is not picking validation when I use the required attribute, how can I add validation for this within a js script that will check against the values in this html form before submitting

I think maybe you get the errors because the HTML tags were not opened and closed in the correct order, and you had an opened div that needed to be closed. Try validating the HTML code. I think it can cause problems if your html is not valid.
I added these attributes to your HTML (and validated it), and also some CSS to see the validation result.
<input type="text" id="link" class="form-control" name="output[link]" required="true" pattern="^http.*">
<input id="address" class="form-control" name="output[address]" required="true" pattern=".*street.*">
and
:invalid {
border: 1px solid red;
}
This works and validates as expected.
:invalid {
border: 1px solid red;
}
input {
margin: 1em
}
<div id="container">
<header>
<h1>Production Form</h1>
</header>
<div class="content">
<div class="row">
<article class="col-xs-12">
<form id="cf-task-form">
<section>
<div class="row form-group">
<div class="col-xs-3">
<label for="link">Link</label>
<input type="text" id="link" class="form-control" name="output[link]" required="true" pattern="^http.*">
</div>
<div class="col-xs-3">
<label for="address">Address</label>
<input id="address" class="form-control" name="output[address]" required="true" pattern=".*street.*">
</div>
<div class="col-xs-3">
<label for="research">Research</label>
<select id="research" name="output[research]">
<option value="0">0</option>
<option value="1">1</option>
</select>
</div>
<div class="col-xs-offset-6 col-xs-6">
<input type="button" class="btn sub-btn pull-right" id="submit-btn" value="Submit" tabindex="10">
</div>
</div>
</section>
</form>
</article>
</div>
<div class="clear"></div>
</div>
</div>
Note that the validation patterns are only for testing and not real patterns that should be used!
I used this page as reference: https://developer.mozilla.org/en-US/docs/Learn/Forms/Form_validation

If you want the required attribute to work, I think you need to change your last input type to "submit" :
<input type="submit" class="btn sub-btn pull-right" id="submit-btn" value="Submit" tabindex="10">
But I agree that it would be great to add some JS if you want to do proper form validation. I see some people shared useful links on the subject.

<form id="cf-task-form" onsubmit="return validateForm()">
const link = document.querySelector("#link").value
const Address = document.querySelector("#Address").value
const research = document.querySelector("#research").value
function validateForm() {
if (link == '') {
alert("filled out url");
return false;
}
else if (Address == '') {
alert("filled out Address");
return false;
}
else if (research == '') {
alert("filled out research");
return false;
}
}

Weird issue with hiding checkboxes on mobile

So I've been working on a back-end interface for where I'm interning, and everything's been going smoothly mainly. I made a page where you insert a customer. there's a checkbox to add shipping information, and the fields are hidden, and only shown when the checkbox is ticked. it is also required when its showing. i did the same thing for a Tax Exempt check box, where it hides a field to enter a tax id, and is only required when its checked and showing, otherwise, it isn't required. both of these features work great on pc, and theyre coded exactly the same. However; when i go to try it on mobile, the shipping checkbox works, and drops down the fields to enter the info. Yet, the tax exempt box doesnt show the field to enter the Tax ID.
Shipping html:
<div id="changeShipInputs">
<div class="form-group">
<div class="col-md-12">
<input id="Sstreet" name="Sstreet" type="text" maxlength="150" placeholder="Street Name (required)" class="form-control">
</div>
</div>
<div class="form-group">
<div class="col-md-4">
<input id="Scity" name="Scity" type="text" maxlength="35" placeholder="City (required)" class="form-control">
</div>
<div class="col-md-4">
<input id="Sstate" name="Sstate" type="text" maxlength="35" placeholder="State (required)" class="form-control">
</div>
<div class="hidden-lg hidden-md"> </div>
<div class="col-md-4">
<input id="Szipcode" name="Szipcode" type="text" maxlength="15" placeholder="Zip (required)" class="form-control">
</div>
</div>
</div>
Tax html:
<div id="changeTaxInputs">
<div class="form-group">
<div class="col-md-3">
<input id="taxID" name="taxID" type="text" maxlength="15" placeholder="Tax ID: (required)" class="form-control">
</div>
</div>
</div>
<hr>
<div class="col-xs-12">
<div class="form-group">
<label for="comment">Notes:</label>
<textarea class="form-control" rows="5" maxlength="255" name="comment" id="comment"></textarea>
</div>
</div>
<div class="col-xs-12">
<br>
</div>
Javascript:
var form = $('#myForm'),
checkbox = $('#changeShip'),
chShipBlock = $('#changeShipInputs');
chShipBlock.hide();
checkbox.on('click', function() {
if($(this).is(':checked')) {
chShipBlock.show();
chShipBlock.find('input').attr('required', true);
} else {
chShipBlock.hide();
chShipBlock.find('input').attr('required', false);
}
});
var form = $('#myForm'),
checkbox = $('#changeTax'),
chTaxBlock = $('#changeTaxInputs');
chTaxBlock.hide();
checkbox.on('click', function() {
if($(this).is(':checked')) {
chTaxBlock.show();
chTaxBlock.find('input').attr('required', true);
} else {
chTaxBlock.hide();
chTaxBlock.find('input').attr('required', false);
}
});
The first script is the shipping, the second is the tax.
can anyone tell me why JUST THE TAX BOX wont work on mobile, yet the shipping box works fine on mobile. They both work great on desktop.

Since it's working on JSFiddle correctly, my guess is that maybe a containing div or element is not closed correctly. Compare the containers of the changeShipInputs and changeTaxInputs closely and report back.

Detect the name of required field and not validated when submit a form

I create a form in html5 like this example :
<form action="/my/url/insert.php" method="POST">
<div class="row">
name <input name="name" required/>
</div>
<div class="row">
type <input name="type" required/>
</div>
<div class="row">
year <input name="year" required/>
</div>
....
<div class="row">
album <input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save"/>
</div>
</form>
<script>
$('form').submit(function(){
console.log('test');
});
</script>
The problem :
I want to detect the name of the required field that are not validated when submiting and logging it.
for example : if I don't fill the input "album" when submit i detect it before the message "a field is required..."
is there a way to do this ?
thank you.

Here you go.. Loop through each input:required field and get its name with .attr.
$('form').submit(function(e) {
e.preventDefault();
$(this).find('input:required').each(function(){
console.log($(this).attr('name'));
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="/my/url/insert.php" method="POST">
<div class="row">
name
<input name="name" required/>
</div>
<div class="row">
type
<input name="type" required/>
</div>
<div class="row">
year
<input name="year" required/>
</div>
....
<div class="row">
album
<input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save" />
</div>
</form>
Updated
$('form').submit(function(e) {
e.preventDefault();
$(this).find('input:required').each(function(){
if($(this).val()==""){ //check if its empty
console.log($(this).attr('name'));
}
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form novalidate action="/my/url/insert.php" method="POST">
<div class="row">
name
<input name="name" required/>
</div>
<div class="row">
type
<input name="type" required/>
</div>
<div class="row">
year
<input name="year" required/>
</div>
....
<div class="row">
album
<input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save" />
</div>
</form>
Assuming that only required will be the property for validation, above condition will hold good and yea, by default when you say required, browser will have its validation suppressing validation written by you. If you want your validation to work, add novalidate to form as said in one of the comments above..

Select them by property required:
$(function() {
$('form').submit(function(){
$("input:required", $(this)).each(function() {
console.log($(this).attr("name"));
});
});
});
To do a simple required check on your own make a simple "not empty" condition. But for this, your form need the novalidate class, otherwise submit callback will not be triggered and nothing ever happens.
$(function() {
$('form').submit(function(){
$("input:required", $(this)).each(function() {
if( $(this).val() != "" )
console.log($(this).attr("name"));
});
});
});
Full example here: https://jsfiddle.net/vvdh66rb/

You can also do like this:
<form action="/my/url/insert.php" method="POST" onSubmit="return myFunction()">
<div class="row">
<!--I am only giving id to one to show an exmaple you can give to differnt-->
name <input name="name" id="some" required/>
</div>
<div class="row">
type <input name="type" required/>
</div>
<div class="row">
year <input name="year" required/>
</div>
....
<div class="row">
album <input name="album" required/>
</div>
<div class="row">
<input type="submit" value="Save"/>
</div>
</form>
<script>
function myFunction() {
var x = document.getElementById('some').value;
if (x == "" || x == null) {
alert('sadsd');
return false;
//You can give anything else than alert
}
}

How to perform client-side form-validation on password

I am doing a simple sign-up page. For the password stuff, I need to check the new password and confirmed password are the same but no idea how
<div class="row">
<!--New Username-->
<div class="large-4 columns form-text">New Username</div>
<div class="large-8 columns">
<div class="input-icon font-awesome"></div><input type="text" class="form-input" name="username" required>
</div>
</div>
<br/>
<div class="row">
<!--New email-->
<div class="large-4 columns form-text">Email</div>
<div class="large-8 columns">
<div class="input-icon font-awesome"></div><input type="email" class="form-input" name="email" pattern="[a-zA-Z]*#[a-zA-Z]*" required>
</div>
</div>
<br/>
<div class="row">
<!--New Passwrord-->
<div class="large-4 columns form-text">New Password</div>
<div class="large-8 columns">
<div class="input-icon font-awesome"></div><input type="password" class="form-input" name="password" required>
</div>
</div>
<br/>
<div class="row">
<!--Reconfirm new password-->
<div class="large-4 columns form-text">Re-enter Password</div>
<div class="large-8 columns">
<div class="input-icon font-awesome"></div><input type="password" class="form-input" name="password-confirm" required>
</div>
</div>

That's quite a bit of code, but I broke out an example on a fiddle.
Simplified HTML:
<form id="passwordForm" action="#" method="POST">
Password:<br>
<input type="password" id="password"><br>
Confirm Password:<br>
<input type="password" id="confirmPassword"><br>
<input type="submit" id="submitButton" value="Check 'Em">
</form>
<div id="responseDiv"></div>
I used jQuery:
$(document).ready(function () {
$("#submitButton").click(function (e) {
e.preventDefault();
var matched,
password = $("#password").val(),
confirm = $("#confirmPassword").val();
matched = (password == confirm) ? true : false;
if(matched) {
//Submit line commented out for example. In production, remove the //
//$("#passwordForm").submit();
//Shows success message and prevents submission. In production, comment out the next 2 lines.
$("#responseDiv").html("Passwords Match");
return false;
}
else {
$("#responseDiv").html("Passwords don't match...");
return false;
}
});
});
Many times new learners will forget the e.preventDefault(); Without it, the form will submit regardless of any validation. Return false if there is something wrong, and the form will not submit.
There is an event listener on the submit button. If it is clicked, or the enter key is pressed will focused in the form, it will run the validation. If everything is fine, it will post the information to the URL in the action attribute of the form tag.
Another important point is to always re-validate on the server side. If a user has their Javascript turned off the form will post the information regardless of what is in your validation script.

with normal javascript, just adapt to your source code:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script>
function pass() {
var pass_1 = document.forms["myForm"].pass_1.value.length;
var pass_2 = document.forms["myForm"].pass_2.value.length;
if (pass_1 != pass_2) {
alert("the pass and repeat pass must be equal");
return false;
}
return true;
}
</script>
</head>
<body>
<form method="post" action="" name="myForm" onSubmit="pass(); return false;">
<input type="password" placeholder="type your pass" name="pass_1">
<input type="password" placeholder="confirm your pass" name="pass_2">
<input type="submit" value="validate">
</form>
</body>
</html>
the same code above but with the redirect: http://jsfiddle.net/m7BrM/
option 2 use a plugin:
