Im partly there but it would be helpful if any of you guys could send the entire code .
1) Create a form with the below given fields and validate the same using javascript or jquery.
Name : Text box- mandatory
Gender : Radio Button
Age : Text box - Accept Number only - (check for valid Age criteria)
Email : Text box - should be in format example#gmail.com
Website : Text box - should be in format http://www.example.com
Country : Select box with 10 countries
Mobile : Text box - should be a 10 digit number - Display this field only after the user selects a country
Social Media Accounts : Facebook, Google, Twitter (3 checkboxes) - Display Social media section only if selected Country is India
I agree the Terms and Conditions - Checkbox
All fields are mandatory and show error messages for all fields(if not valid)
Only allow to submit form after checking the 'I agree' checkbox.

This is my index.html file. It has JavaScript but when JavaScript validation works >Submit button doesn't perform any action. But when I remove JavaScript code it submits the data to the database.
I need to understand where my code has faults or mistakes and why this is happening. How to validate that the arrival date should be smaller than the departure date.

You should return true at the end of your validate() function if your validation was successful. Right now you always return false. Thats why the button doesn´t seams to work.
Seems like you missed something.
You should return true after succesfull validation.
if (x == "" || x == null) {
alert("First Name must be filled out");
return false;
} else if (y == "" || y == null) {
alert("Last Name must be filled out");
return false;
} else if (!email.match(filter)) {
alert("Enter Proper Email ID");
return false;
} else if (document.getElementById("country").value == "") {
alert("Please select a country");
return false;
} else if (getSelectedValue == null) {
alert("Select Payment Mode")
return false;
} else {
return true;
}
Or just return true after if-else statement.

I'm having issues getting an output box that retrieves the selections on the form.
Also, in one of my if statements I'm assigned to check if the value is between 1 and 999 but I'm drawing a total blank on this. I'm new to coding (Javascript) and this is my first class. Any help with getting this to work would be greatly appreciated.
There are some issues with your code
Redundant else if ()
fsClassChecked variable not declared.
Redundant class when iterate elements document.frmCustOrders.class
Use wrong variable customer should be customerIndex
Wrong condition (customerIndex == -1) change to (customerIndex == "")
//suggested logic for the validateInput() function
function validateInputs()
{
//check payment method
var methodChecked = false;
var fsClassChecked = false;
for (var i=0; i <document.frmCustOrders.length;i++)
{
if (document.frmCustOrders[i].checked ==true)
{
fsClassChecked = true;
vClass = document.frmCustOrders[i].value;
}
}
//check customer index value
var customerIndex = document.getElementById("customer").value;
//retrieve order quantity
var qty = document.getElementById("qty").value;
//validate form data
if (customerIndex == "") //validate customer
{
alert("Please select a customer.")
return false;
}
else if(qty == "" || qty < 1 || qty > 999){
alert("Please enter qty 1-999.")
return false;

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">

I am trying to add a Span after my Input that will have the class "error" and the text "test".
I've tried the append, and insertAfter methods. I can get the code to work on jsfiddle but I cannot get the code to work on my application.
I have put the HTML and JS/Jquery below. My end result would have a Span (with the class error) next to each input with the type text. I would then set a value for this span based on a validation loop.

Most easy way is to add a Div container around the form and just append the warning to that. To effectively append after an element you need to give it a class or id.
var email = $("#email"); //using class instead of input:text
var html = "<span class='error'>TEST!</span>"
email.after( html );
But I personally would like something like this better:
var generateError = function(){
var html = "<div id='error' style='top: 0; left:0; width:100%; height: 50px; background-color: red; text-allign: center; display:none; z-index: 100;'> ERROR!!</div>"
$(body).append( html );
}
var showError = function( text ){
var err = $("#error");
err.html( text );
err.show(500).delay(2000).hide(500);
}
Code is fairly self-explaining, but this will make two functions: generateError and showError.
generateError you need to call before you want to show the error, possibly when the page loads it will add a small header on top of all you other elements and will appear hidden.
showError uses a text argument with the error you want to show. Then it will set the text to the div and show it for two seconds.
This then is more what you are looking for?
$(document).ready(function () {
var input = $("input");
var emailPattern = /\b[A-Za-z0-9._%+-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}\b/;
input.keypress(function (ele) {
// if regex.test( input ) === false
createErrors(ele.target);
})
});
var createErrors = function (ele) {
$('<span>TEST!</span>').insertAfter(ele);
$("#arrival_date").focus();
};
This works on keypress, that means the regex gets checked every time a key is pressed. It also passes the element where the user is typing as parameter, this means that you wont get errors for all input:text, but only for the ones where there is an error.
Updated Fiddle (still not perfect, but if its an school exercise this will help you to finish it :)
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

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;

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.
