Alert in Javascript

On my order site, I have 2 options: pick up and delivery.
When choosing pick up, nothing happens, but when choosing delivery, the delivery address will appear for the user to fill in.
I want to use JS to notify you that you need to enter your shipping address only I you tick the delivery box.
Thank you.

In your code, you appear to have forgotten to close the function validate()'s
curly brackets (never closed the bracket "{").
Always remember to close your brackets.
Hope this helps :).
(still shows errors because incomplete code)

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">

registration form validation using javascript

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

Check specific radio button is checked

I'm just trying to return true/false in one my my jquery methods depending on the check of a 2 radio buttons and if it's selected or not
I've tried several things but have not been able to get this right, it still submit the form without giving error that the buttons are not selected.
HTML Code
<label class="checkout-item" for="payment_1">Cash On Delivery</label>
<input type="radio" name="payment" class="radio" id="payment_1" value="3" iscod="1" onclick="selectPayment(this)">
<label class="checkout-item" for="payment_2">Credit Card / Debit Card</label>
<input type="radio" name="payment" class="radio" id="payment_2" value="9" checked="" iscod="0" onclick="selectPayment(this)">
<label class="checkout-item" for="ECS_NEEDINSURE_1">Home Delivery</label>
<input name="shipping" type="radio" id="ECS_NEEDINSURE_1" value="3" checked="true" supportcod="1" insure="0" class="radio" onclick="selectShipping(this)">
<label class="checkout-item" for="ECS_NEEDINSURE_2">Self-pickup</label>
<input name="shipping" type="radio" id="ECS_NEEDINSURE_2" value="8" supportcod="1" insure="0" class="radio" onclick="selectShipping(this)">
Javascript
function checkOrderForm(frm) {
var paymentSelected = false;
var shippingSelected = false;
// Check whether the payment method is selected
for (i = 0; i < frm.elements.length; i++) {
if (frm.elements[i].name == 'shipping' && frm.elements[i].checked) {
shippingSelected = true;
}
if (frm.elements[i].name == 'payment' && frm.elements[i].checked) {
paymentSelected = true;
}
}
if (!shippingSelected) {
alert(flow_no_shipping);
return false;
}
if (!paymentSelected) {
alert(flow_no_payment);
return false;
}

If I'm understanding your question correctly, you would only like this test to pass if BOTH of the radio buttons are checked. Currently, as long as one radio button in each group is checked, the code variable will be set to true, ignoring the state of the other radio button.
For example, if ONLY one of your shipping radio buttons was checked, the shippingSelected variable would be set to true and it would remain true.
A way to fix this is to begin with shippingSelected and paymentSelected set to true, and if one of the radio buttons are found to be unchecked, the variable will be set to false.
Here's an example:
var paymentSelected = true;
var shippingSelected = true;
// Check whether the payment method is selected
for (i = 0; i < frm.elements.length; i++) {
if (frm.elements[i].name == 'shipping' && !frm.elements[i].checked) {
shippingSelected = false;
}
if (frm.elements[i].name == 'payment' && !frm.elements[i].checked) {
paymentSelected = false;
}
}

You can use $("#payment_1").checked to check whether the radio is checked or not. Similarly you could use other ID's to check whether they are selected or not.
Here is the fiddle:
https://jsfiddle.net/bf8bo43t/

Try below code,
HTML
<form method="post" name="frm_payment_types">
<label class="checkout-item" for="payment_1">Cash On Delivery</label>
<input type="radio" name="payment" class="radio" id="payment_1" value="3" iscod="1" onclick="selectPayment(this)">
<label class="checkout-item" for="payment_2">Credit Card / Debit Card</label>
<input type="radio" name="payment" class="radio" id="payment_2" value="9" iscod="0" onclick="selectPayment(this)">
<label class="checkout-item" for="ECS_NEEDINSURE_1">Home Delivery</label>
<input name="shipping" type="radio" id="ECS_NEEDINSURE_1" value="3" supportcod="1" insure="0" class="radio" onclick="selectShipping(this)">
<label class="checkout-item" for="ECS_NEEDINSURE_2">Self-pickup</label>
<input name="shipping" type="radio" id="ECS_NEEDINSURE_2" value="8" supportcod="1" insure="0" class="radio" onclick="selectShipping(this)">
<br />
<input type="submit" name="submit" onclick="return checkOrderForm();" />
</form>
Javascript
<script type="text/javascript">
function validateForm(){
var payment_1 = document.getElementById('payment_1');
var payment_2 = document.getElementById('payment_2');
var ECS_NEEDINSURE_1 = document.getElementById('ECS_NEEDINSURE_1');
var ECS_NEEDINSURE_2 = document.getElementById('ECS_NEEDINSURE_2');
if((payment_1.checked == true || payment_2.checked == true) && (ECS_NEEDINSURE_1.checked == true || ECS_NEEDINSURE_2.checked == true)){
return true;
}
else if(payment_1.checked == false && payment_2.checked == false){
alert("Please select Cash On Delivery or Credit Card / Debit Card.");
}
else if(ECS_NEEDINSURE_1.checked == false && ECS_NEEDINSURE_2.checked == false){
alert("Please select Home Delivery or Self-pickup.");
}
return false;
}

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="Yes" name="lien" id="lien" required="yes" onchange="showhideForm(this.value);"/><label for="lien">Lien</label>
<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) {
if (lien == "Yes") {
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">
<label for="lname">Lienholder Name:</label>
<input type="text" name="lienlname" validateat="onSubmit" validate="maxlength" id="lienlname" size="54" maxlength="120" message="Please enter lienholder name." value="">
</p>
<p>
<label for="laddress">Lienholder Address:</label>
<input type="text" name="lienladdress" validateat="onSubmit" validate="maxlength" id="lienladdress" size="54" maxlength="120" message="Please enter lienholder address." value="">
</p>
<p>
<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.
