Doing a web site with validation form - javascript

I currently trying to make a website with a validating booking form for a university a project about a university portal. It used to work with my javascript validation until I added to validate time. Problem is sumbit button not working when I add to validate time and whenever I remove it is working.

Any suggestions?

You should do this kind of thing with required.
<input type="email" required>
Note: The required attribute works with the following input types: text, search, url, tel, email, password, date pickers, number, checkbox, radio, and file.
(https://www.w3schools.com/tags/att_input_required.asp)
There also exist pattern. For example, if you want to allow only six letters
<input type="text" pattern="[A-Za-z]{6}" required>
Here's a stackoverflow question that gives more information.

As i can see, the problem isn't on validateDate but on validateWorkshop. If you try to submit a blank form, without choosing a workshop, reason.length gets value 5. But if you pick a workshop, reason.length gets 13.
Not that i recomend your validation but to get this working, i just added a var error = ""; at the begining of validateWorkshop.
/** Validation Form**/
function validateFormOnSubmit(contact) {
reason = "";
reason += validateName(contact.name);
reason += validateEmail(contact.email);
reason += validatePhone(contact.phone);
reason += validateID(contact.id);
reason += validateWorkshop(contact.workshop);
reason += validateDate(contact.date);
console.log(reason);
if (reason.length > 0) {
return false;
} else {
return true;
}
}
/**Validate name**/
function validateName(name) {
var error = "";
if (name.value.length == 0) {
document.getElementById('name-error').innerHTML = "Please enter your First name.";
var error = "1";
} else {
document.getElementById('name-error').innerHTML = '';
}
return error;
}
/**Validate email as required field and format**/
function trim(s) {
return s.replace(/^\s+|\s+$/, '');
}
function validateEmail(email) {
var error = "";
var temail = trim(email.value);
var emailFilter = /^[^#]+#[^#.]+\.[^#]*\w\w$/;
var illegalChars = /[\(\)\<\>\,\;\:\\\"\[\]]/;
if (email.value == "") {
document.getElementById('email-error').innerHTML = "Please enter your Email address.";
var error = "2";
} else if (!emailFilter.test(temail)) { /**test email for illegal characters**/
document.getElementById('email-error').innerHTML = "Please enter a valid email address.";
var error = "3";
} else if (email.value.match(illegalChars)) {
var error = "4";
document.getElementById('email-error').innerHTML = "Email contains invalid characters.";
} else {

return error;

This is my exception handling code that I am trying to get working. However, no matter how much I modify it, it never shows correctly. I have ran it in Chrome and have tried using a debugger to help however I am still unable to show the exceptions when I click the submit button.

It looks like you try to access a non existing field.
Here you already get the values of the fields
var fname = document.getElementById("firstname").value;
var lname = document.getElementById("lastname").value;
var email = document.getElementById("emailaddress").value;
And in your comparisons you try to access a value field again. But you already have the plain value
if(!(isNaN(lname.value)) || (lname.value === "")){
}
Do it this way instead
if(!(isNaN(lname)) || (lname === "")){
}

Trying to store a completed form into an array

I'm creating a registration page and am currently attempting to store the inputs of the form into an array. I'm using
var form_inputs = document.getElementsByClassName("form_input");
to store the inputs in the same place, however if I try to alert form_inputs to test if anything is actually being stored, it just alerts "Undefined".
function validate_form(event) {
var forename = document.getElementById("forename");
var surname = document.getElementById("surname");
var username = document.getElementById("username");
var password = document.getElementById("password");
var re_password = document.getElementById("re_password");
var email = document.getElementById("email");
var errors = 0
var special_chars = "<>#!#$%^&*()_+[]{}?:;|'\"\\,./~`-=";
var form_inputs = document.getElementsByClassName("form_input");
if (forename.value == "") {
//document.getElementById("forename").style.background = "red";
forename_confirmation.style.visibility = 'visible';
var errors = errors + 1
} else
for (var i = 0; i < forename.value.length; i++) {
if (special_chars.indexOf(forename.value.charAt(i)) != -1) {
forename_chars.style.visibility = 'visible'
}
}
if (surname.value == "") {
//document.getElementById("surname").style.background = "red";
surname_confirmation.style.visibility = 'visible';
var errors = errors + 1
} else

console.log(form_inputs);

Action attribute not working on JS validated form

The files are in the the correct locations, both the form page and form complete page are in the same folder. When I click submit, it validates the form correctly, but if everything is entered correctly and validates, it does nothing, just takes away the asterisks like it's supposed to in the js. I want it to link to the form_complete.html page after you hit submit and the validation runs, but after it validates nothing happens,
The html:
<form id="contactform" action="form_complete.html" method="post">
<p class = "labelp">
<label for="name">Name: </label>
<input type="text" name="name" id="name" placeholder="Enter your name" >

Making JS Alert Look More Professional

Can someone help me make this alert look much nicer? Like Maybe split up Each text box on its own line? I can not figure out how to make this look a lot cleaner and not just all piled on one line.
To see alert hit Lien radio button and then hit next without filling textboxes
http://jsfiddle.net/t4Lgm0n2/9/
function validateForm(){
var QnoText = ['lien']; // add IDs here for questions with optional text input
var ids = '';
flag = true;
for (i=0; i<QnoText.length; i++) {
CkStatus = document.getElementById(QnoText[i]).checked;
ids = QnoText[i]+'lname';
var eD = "";
if (CkStatus && document.getElementById(ids).value == '') {
eD = eD+' lienholder name';
document.getElementById(ids).focus();
flag = false;
}
ids2 = QnoText[i]+'laddress';
if (CkStatus && document.getElementById(ids2).value == '') {
eD=eD+' lienholder address';
document.getElementById(ids2).focus();
flag = false;
}
ids3 = 'datepicker2';
if (CkStatus && document.getElementById(ids3).value == '') {
eD=eD+' lien date';
document.getElementById(ids3).focus();
flag = false;
}
if(eD!="") alert("Please enter "+eD);
}
return flag;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>

<input type="radio" value="None" name="lien" id="nolien" onchange="showhideForm(this.value);"/><label for="nolien">No Lien</label>
<script type="text/javascript">
function showhideForm(lien) {

document.getElementById("div1").style.display = 'block';
document.getElementById("div2").style.display = 'none';
}
else if (lien == "None") {
document.getElementById("div2").style.display = 'block';
document.getElementById("div1").style.display = 'none';
$("#div1 > .clearfix input:text").val("");
}
}
</script>
<div id="div1" style="display:none">
<div class="clearfix">

<input type="text" name="lienlname" validateat="onSubmit" validate="maxlength" id="lienlname" size="54" maxlength="120" message="Please enter lienholder name." value="">

<label for="ldate">Date of Lien:</label>
<input type="text" name="lienldate" id="datepicker2" mask="99/99/9999" value="">
</div>
</div>
<div id="div2" style="display:none">
<!---You are not qualified to see this form.--->
</div>
<input type="submit" name="submit" value="Next" onclick="validateForm()">
You can use new line characters \n to make text more readable:
var eD = [];
if (CkStatus && document.getElementById(ids).value == '') {
eD.push('Please enter lienholder name');
document.getElementById(ids).focus();
flag = false;
}
// ...
if (eD.length) alert(eD.join('\n'));
As you can see I'm also pushing error messages into ed array, which makes it more convenient to concatenate resulting message using .join() method.

Javascript form verification for this

I need to do a Javascript verification of the fields. I need to know how to make for each span of every label how to make it display the write message.
At the moment the html code is:
<form method="post" id="contactForm" onclick="return main();">
<fieldset>
<div class="subscribe">
<label for="firstName">First name:</label>
<input type="text" name="firstName" id="firstName"/>
<span id="fnameMessage" class="infomessage">
Your first name should contain at least 2 alpha characters.
</span>
</div>
<div class="subscribe">
<label for="lastName">Last name:</label>
<input type="text" name="lastName" id="lastName"/>
<span id="lnameMessage" class="infomessage">
Your last name should contain at least 2 alpha characters.
</span>
</div>
<div class="subscribe">
<label for="title">Title:</label>
<select name="title" id="title">
<option value="1"> Mr. </option>
<option value="2"> Ms. </option>
<option value="3"> Mrs. </option>
<option value="4"> Miss. </option>
<option value="5"> Master. </option>
</select>
</div>
<div class="subscribe">
<label for="hNumber">Health Authority Number:</label>
<input type="text" name="number" id="hNumber"/>
<span id="hanMessage" class="infomessage">
Your ZHA number should be in the form of 6 digit integer prefixed wit the letters ZHA.
</span>
</div>
<div class="subscribe">
<label for="email">Email address: </label>
<input type="email" name="email" id="email"/>
<span id="emailMessage" class="infomessage">
Your email address should be as example: example#difexample.com.
</span>
</div>
<div class="subscribe">
<label for="phoneNumber">Telephone number:</label>
<input type="text" name="phoneNumber" id="phoneNumber"/>
<span id="phoneMessage" class="infomessage">
Your phone number should contain 11 numeric characters.
</span>
</div>
<div class="button">
<input id="btn1" type="submit" value="Submit" />
</div>
</fieldsed>
</form>
The javascript code that I've done it's:
function main() {
document.getElementById("contactForm").onsubmit = validateAll,
document.getElementById("firstName").onblur = validateName,
document.getElementById("lastName").onblur = validateName,
document.getElementById("phoneNumber").onblur = validatePhone;
}
function validateName() {
var test1 = fieldEmpty(this);
var test2 = fieldLength(this,2,50);
var test3 = fieldCharacters(this, "A");
var result = test1&&test2&&test3;
return result;
}
function validatePhone() {
var test1 = fieldEmpty(this);
var test2 = fieldLength(this,11,11);
var test3 = fieldCharacters(this,"N");
var result = test1&&test2&&test3;
return result;
}
function fieldEmpty(id) {
var valid = true;
if (id.value == "") {
valid = false;
alert("Field Empty");
}
return valid;
}
function fieldLength(id,min,max) {
var valid = true;
var lng = id.value.length;
if (lng < min || lng > max) {
valid = false;
alert("Field Length");
}
return valid;
}
function fieldCharacters(id,character) {
var letters = /[a-zA-Z]/;
var numbers = /[0-9]/;
var patternTest;
var valid = true;
if(character == "N") {
patternTest = numbers;
}
else if(character == "A") {
patternTest = letters;
}
valid = patternTest.test(id.value);
if (!valid) {
alert("Pattern Fail");
}
return valid;
}
function validateField() {
var noErrors = true;
// var input = document.getElementById(this);
if(this.value.length<2) {
noErrors = false;
alert("You need to input more than 1 character in " + this.id);
}
if(noErrors==false) {
var temp = document.getElementById(this.id + "firstnamemessage");
temp.className = "infomessage";
}
}
function validateAll() {
return false;
}
window.onload = main();
