why do i get two different setCustomValidity messages? - javascript

i am very new to web dev and javascript. i am working on a project from a book and building a simple web app that takes orders for coffee. i am using the constraint validation api and i am stuck on that. there is a function that tests the input into the email field against a regular expression and it returns true if the email address has 'authorized email address'. as long as it doesn't match i try to submit the form and i get the expected message '**** is not an authorized email address'. but when it it does match the pattern and the isCompanyEmail function returns true i still get a validity message, just a different one saying 'please match the requested format'. does anyone have any idea what could be causing this? i am including the validation code and form code.
validation code:
(function(window){
'use strict';
var App = window.App || {};
var Validation = {
isCompanyEmail: function(email){
return /.+#bignerdranch\.com$/.test(email);
}
};
App.Validation = Validation;
window.App = App;
})(window);
formhandler code:
(function(window){
'use strict';
var App = window.App || {};
var $ = window.jQuery;
function FormHandler(selector){
if (!selector) {
throw new Error('No selector provided!');
}
this.$formElement = $(selector);
if (this.$formElement.length === 0) {
throw new Error('Could not find element with selector ' + selector);
}
};//end constructor
FormHandler.prototype.addSubmitHandler = function(fn){
console.log('Setting submit handler for form');
this.$formElement.on('submit', function(event){
event.preventDefault();
var data = {};
$(this).serializeArray().forEach(function(item){
data[item.name] = item.value;
console.log(item.name + ' is ' + item.value);
});
console.log(data);
fn(data);
this.reset();
this.elements[0].focus();
});
};
FormHandler.prototype.addInputHandler = function(fn){
console.log('Setting input handler for form');
this.$formElement.on('input', '[name="emailAddress"]', function(event){
var emailAddress = event.target.value;
console.log(fn(emailAddress));
var message = '';
if(fn(emailAddress)){
event.target.setCustomValidity(message);
}else{
message = emailAddress + ' is not an authorized email address!';
event.target.setCustomValidity(message);
}
});
};
App.FormHandler = FormHandler;
window.App = App;
})(window);

Inserting values of checkbox back to form from local storage

I am getting two values of checkbox one is always false with type hidden. I created a local storage and where I stored value of checkbox. I want to put values back into my form from local storage. Can somebody please help me with that.
$(document).ready(function() {
InitalizeCache(GetKey());
});
function GetKey() {
var key = "local";
return key;
}
function CacheSpikeData() {
var form = $("#application-form").serializeArray();
CacheData(form, GetKey());
}
function InitalizeCache(key) {
window.onload = function() {
RecoverFormFromLocalStorage(key);
}
}
function RecoverFormFromLocalStorage(key) {
if (localStorage.getItem(key) !== null) {
var recover = confirm("You have some unsaved changes. Do you want to continue from where you left? ");
if (recover == true) {
RecoverFormFromLocalStorage2(key);
return true;
} else {
clearLocalStorage(key);
return false;
}
}
}
function ShowSpikeData() {
alert(localStorage.getItem(GetKey()));
}
function LoadSpikeData() {
RecoverFormFromLocalStorage2(GetKey());
}
function clearLocalStorage(key) {
localStorage.removeItem(key);
}
function CacheData(jsoNform, key) {
localStorage.setItem(key, JSON.stringify(jsoNform));
}
function RecoverFormFromLocalStorage2(key) {
var cache = localStorage.getItem(key);
var record = JSON.parse(localStorage.getItem(key));
if (cache !== null) {
$("#application-form *").filter(':input').each(function() {
if (this.type != "hidden") {
var cache = localStorage.getItem(key);
var record = JSON.parse(localStorage.getItem(key));
var cacheValue = $(record).find("Name=MyStringValue");
this.value = cacheValue;
alert(this.name + this.hidden);
}

I am simply trying to insert values back to form without deleting the hidden value of checkbox, but picking up the current value.
Try changing InitalizeCache to this
function InitalizeCache(key) {
RecoverFormFromLocalStorage(key);
}
Rename RecoverFormFromLocalStorage2 to populateDataFromLocalStorage and change to this
function populateDataFromLocalStorage(key) {
var cache = localStorage.getItem(key);
if (cache !== null) {
var formJson = JSON.parse(cache);
$("#application-form *").filter(':input').each(function() {
var name = $(this).attr('name');
var formRecord = formJson.find(function(record) {
return name === record.name;
}) || {};
if (this.type === "text") {
$(this).val(formRecord.value);
}
if (this.type === "checkbox") {
$(this).prop('checked', formRecord.value === 'true');
}
});
}
}
Update LoadSpikeData() to call the correct function name populateDataFromLocalStorage
Also the inputs at the end should have type="button"

Adding a node to html page with javascript

This is my first time with javascript. I'm making a basic login page where there is a control for the email input. I would like to put an error message of some kind when someone gives an email address with illegal symbol. Here my code:
<!DOCTYPE html>
<html>
<head>
<title>Home</title>
<meta charset="UTF-8">
</head>
<body>
<div>
<form action="Home.html" method="post">
<label for="id">Username</label>
<input type="text" name="id" id="id" value="" />
<br/>
<label for="pass">Password</label>
<input type="password" name="pass" id="pass" value="" />
<br/>
<label for="email">Email</label>
<input type="email" name="email" id="email" value="" />
<br/>
<script type="text/javascript">
function checkEmail ()
{
var emailObject = document.getElementById("email");
var email = emailObject.getAttribute("value").toString();
var error = document.createTextNode("Uncorrect email");
var result = email.search("/[^(a-z | A-Z | 0-9 | #)]/");
if(result !== -1)
{
emailObject.appendChild(error);
}
}
</script>
<button type="button" onclick="checkEmail()"> Confirm </button>
</form>
</div>
</body>
</html>
I have a function I use to validate email addresses, it uses regex. I would suggest jQuery just to show/hide the error message.
function validEmail(val){
if(val.length < 6 || val.length > 255) return false;
return new RegExp(/^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,6}$/).test(val);
}
$(function(){
$("#email").on("change", function(){
var email = $("#email").val();
if(!validEmail(email)){
$("#emailError").show();
} else {
$("#emailError").hide();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<!-- Some Inputs here -->
<span id='emailError' style='display: none;'>Please enter a valid email address</span><br>
<input type='email' id='email' name='email' placeholder='Email Address' />
<!-- More Inputs here -->
<button type='submit'>Submit</button>
</form>
you're trying to append something to an input element (email input, in this case). I'd suggest to append it to your main div, which in this case I have identified as "YOUR_ID".
Also, I suggest you a more efficint way to check a valid email.
follow the below example
<body>
<div id="YOUR_ID">
<form action="Home.html" method="post">
<label for="id">Username</label>
<input type="text" name="id" id="id" value="" />
<br/>
<label for="pass">Password</label>
<input type="password" name="pass" id="pass" value="" />
<br/>
<label for="email">Email</label>
<input type="email" name="email" id="email" value="" />
<br/>
<script type="text/javascript">
function checkEmail ()
{
var emailObject = document.getElementById("email");
var divObject = document.getElementById("YOUR_ID");
var email = emailObject.getAttribute("value").toString();
var error = document.createTextNode("Uncorrect email");
var check = /^([\w-]+(?:\.[\w-]+)*)#((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;
var result = check.test(email);
if(result !== -1)
{
divObject.appendChild(error);
}
}
</script>
<button type="button" onclick="checkEmail()"> Confirm </button>
</form>
</div>
</body>

Jquery event handling when a checkbox is clicked

edit Updated full code :
I'm working on my first Javascript case i'm stuck here :
I have the following :
$(document).ready(function()
{
$('input, select').on('focus' ,swapPersonClass);
//Blur = Bind an event handler to the “blur” JavaScript event, or trigger that event on an element.
$('input, select').on("change", updateCart);
}
);
// Functions
var swapPersonClass = function()
{
var expression = $(this).attr('id');
switch(expression)
{
case "fullname":
break;
case "email":
$("#arm").removeClass().addClass("pointemail");
break;
case "countpizzas":
$("#arm").removeClass().addClass("pointamount");
break;
default:
$("#arm").removeClass().addClass("pointothers");
}
};
var updateCart = function () {
var change = $(this).attr('id');
console.log(change);
$('input, select').each(function ()
{
switch (change)
{
case "fullname":
$("#displayname").text($('#fullname').val() + ',');
break;
case "countpizzas":
aantalpizzas = $("#countpizzas").val();
if (aantalpizzas > 1) {
$('.plural').show();
} else {
$('.plural').hide();
};
$("#displayamount").text(aantalpizzas);
console.log(aantalpizzas);
break;
case "pizzatype":
PrijsPizza = $("#pizzatype option:selected").data("price");
console.log(PrijsPizza);
break;
case "YesOption":
$("#toppings").show();
break;
case "NoOption":
$("#toppings").hide();
break;
case "toppings":
updateTopping();
break;
};
$("#currenttotal").text(aantalpizzas * PrijsPizza );
});
};
var updateTopping = function ()
{
$(".chk_topping").change(function()
{
var selected_topping = $(this).attr('data-value');
switch(selected_topping)
{
case "salami":
$("#currenttotal").text(aantalpizzas * PrijsPizza );
PrijsTopping += 0.30;
break
}
});
};
var PrijsTopping = 0.30;
var aantalpizzas = 0;
var PrijsPizza = 0;

Why my checkboxes keep telling me it's undefined when selecting them ?
I'm realy not good at javascript so my code will probably be sh*t
Try this
var selected_topping = $(this).data('value');
http://jsfiddle.net/f4Lghy6p/
Found it.
i'm searching for a specefic ID in my select en input fields :
$('input, select').on("change", updateCart);
My checkboxes are located in a DIV with an input fields which don't have an ID.

Create a link based on values from a Html form and redirect them to it

What I'm trying to do is to redirect people to a link depending of what they have summited on the form (the link is built using the values from the form fields)
This is the Form:
<form id="form">
<div class="formbox">
<div class="radio-toolbar">
<input type="radio" id="iconapp1" name="department" value="1250"/>
<label for="iconapp1">PP</label><br>
<input type="radio" id="iconapp2" name="department" value="944"/>
<label for="iconapp2">EP</label><br>
</div>
<div class="radio-bar1">
<input type="radio" id="enginemake1" name="enginemake" value="6"/>
<label for="enginemake1"> Chevrolet</label><br>
<input type="radio" id="enginemake2" name="enginemake" value="8"/>
<label for="enginemake2"> Chrysler</label><br>
</div>
<div class="bodyvertdivision1"></div>
<div class="radio-bar3">
<select name="powerrange">
<option id="powerrange1" value="28">100</option>
<option id="powerrange2" value="128">200</option>
<option id="powerrange3" value="228" selected>300</option>
</select>
</div>
<div class="bodyvertdivision1"></div>
<div class="radio-bar4">
<input type="radio" id="location1" name="location" value="store"/>
<label for="location1"> America (NT - ST)</label><br>
<input type="radio" id="location2" name="location" value="store.au"/>
<label for="location2"> Australia and Oceania</label><br>
</div>
<div class="radio-bar2">
<input onclick="goToPage();" type="button" class="buttonmyapp" value="Submit" />
</div>
</div>
</form>
The link I'm trying to build using the values selected will look like this:
http://{location}.mydomain.com/product-catalog.aspx?section=-{department}-{enginemake}-{powerrange}-
Each bracketed section needs to be replaced by the value of the select with the corresponding name.
First include the jquery library link or download js and link
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type="text/javascript">
function goToPage(){
var location = $('input[name=location]:checked').val();
var department = $('input[name=department]:checked').val();
var enginemake = $('input[name=enginemake]:checked').val();
var powerrange = $('select[name=powerrange]').val();
window.location.href = "http://"+location+".mydomain.com/product-catalog.aspx?section=-"+department+"-"+enginemake+"-"+powerrange+"-";
}
</script>
After the goToPage function on the submit button validates the response change the src attribute of the form should work fine.
So in jQuery it should look something like
var location = $('input[name=location]:checked', '.radio-bar4').val();
var dept = $('input[name=location]:checked', '.radio-bar4').val();
var engine = $('input[name=enginemake]:checked', '.radio-bar1').val();
var power = $('powerrange').val() ;
var domain = "http://"+ location+".mydomain.com/product-catalog.aspx?section=-"+dept+"-"+engine+"-"+power+"-";
$("#form").attr("action", domain);
you can try this
HTML
<select id="powerrange" name="powerrange">
JAVASCRIPT
function goToPage()
{
var location;
var department;
var enginemake;
var powerrange;
pName = document.getElementById('powerrange');
powerrange = pName.options[pName.selectedIndex].value;
var form = document.getElementById('form');
var ele = form.getElementsByTagName('input');
for(var i=0;i<ele.length;i++)
{
if(ele[i].getAttribute('type')=='checkbox')
{
if(ele[i].getAttribute('name')=='department')
{
if(ele[i].checked)
department = ele[i].value;
}
else if(ele[i].getAttribute('name')=='enginemake')
{
if(ele[i].checked)
enginemake = ele[i].value;
}
else if(ele[i].getAttribute('name')=='location')
{
if(ele[i].checked)
location = ele[i].value;
}
else;
}
}
var url = "http://"+ location+".mydomain.com/product-catalog.aspx?section=-"+department+"-"+enginemake+"-"+powerrange+"-";
form.setAttribute('action',url);
form.submit();
}

Firebug returning odd error for one getElementById

I have the following lines of js
var select_container = "container_"+parts[2];
var get_container = document.getElementById(select_container);
The function this is part of is failing and when I look in firebug it returns get_container as undefined. I have checked select_container is the correct value and that there isn't a duplicate id on page.
This is called by an onclick event so I can't see waiting for the page to load being an issue (the result is same no matter how long I wait).
revelent html example:
<div id="container_0">
I'm stumped!
edit
This is all the Javascript from the parent functions
/*detects links in the form editor and uses them to adjust the layout*/
window.onload = function () {
clickDetection();
} /*detect clicks on interesting links*/
function clickDetection() {
var canvas = document.getElementById("content");
var dumbLinks = canvas.getElementsByTagName("a");
for (var i = 0; i < dumbLinks.length; i++) {
dumbLinks[i].onclick = function () {
clickRoute(this);
return false
};
}
} /*reroute click behaviour to correct function*/
function clickRoute(link_object) {
var linkId = link_object.getAttribute("id");

Change this:
document.removeChild(get_container);
to this:
get_container.parentNode.removeChild(get_container);
or if the containers are a direct descendant of body, then you could do this:
document.body.removeChild(get_container);
