Get date from date calculation in JavaScript

I'm trying to build a calculator that calculates various dates based on a user's input. The user selects the date of when a document was issued and then 2 things need to happen:
The expiry date is calculated by adding X number of days to the date issued and displayed to the user
The recommended application date is calculated based on the expiry date minus X number of days
The first one I got working (not in a very elegant way but it works for this part)
The second part (recommended application date), I can't get to work. I've done a lot of research and can't find a solution. (I'm a beginner)
I'm thinking maybe "onchange" is perhaps not the right event but I can't find information on another event that applies to this situation. Or is it an issue with how the functions are structured? Or something else completely? I have also tried moment.js and a few other libraries but what I have in the codepen below is what have gotten me the furthest thus far.
The codepen with everything is here: https://codepen.io/locheia1985/pen/XWBMGXZ
And here is the code:
function setSecondDate() {
var days = document.getElementById('select').value;
var date = new Date(document.getElementById('date1').value);
date.setDate(date.getDate() + parseInt(days));
document.getElementById('date2').valueAsDate = date;
}
function setThirdDate() {
var days3 = document.getElementById('select2').value;
var date2 = new Date(document.getElementById('date2').value);
date2.setDate(date2.getDate() - parseInt(days3));
document.getElementById('date3').valueAsDate = date3;
console.log(date2);
}

Any help would be appreciated

I think additional to the typo the onChange event only fires when a user interacts with the component - not when you programmatically set it. To get that setThirdDate there are some options but the clearest way is to just do the work you would have wanted done on the second event at the same time.
A refactor of this that fixes the typo and sets both dates is:
to change:
<input type="date" onchange="setSecondDate();" id="date1">
to
<input type="date" onchange="handleDateIssuedChanged();" id="date1">
and add (this also renames the setters to be clearer):
function handleDateIssuedChanged() {
setExpiryDate();
setRecommendedDate();
}

disabling form submit in html and css only

I am adding a code block to a page where all js is disabled and stripped out. I want to add a recaptcha to a form to cut down on spam. I've nearly got it, but can't get it to work.
My questions are:
The js code I am using to validate the required fields gets stripped. Is there any way to put the validation back in without using js?
I can't figure out how to connect the enable submit to the recapthca checkbox.
Here's the code as far as I've got it to work...
<!-- Note :
- You can modify the font style and form style to suit your website.
- Code lines with comments Do not remove this code are required for the form to work properly, make sure that you do not remove these lines of code.
- The Mandatory check script can modified as to suit your business needs.
- It is important that you test the modified form before going live.-->

You can try using required on input elements in the form,
for the captcha you should add some functionality when you click on submit you should check if the captcha checkbox was clicked (right now theres some jquery code on it but you dont have jquery on your web)

Use the disabled attribute!
Here is an example:
<form> <input type = "submit" disabled="disabled">Submit</input></form>
Using this will grey-out the button!

javascript is not working

validationMessage = validationMessage + ' - UserName is missing\r\n';
document.getElementById('errorUserNameMissing').style.display = 'block';
valid = false;
} else {
document.getElementById('errorUserNameMissing').style.display = 'none';
}
if ((document.getElementById('pass').value = 'Enter Password…')||(document.getElementById('pass').value.length == 0) ){
validationMessage = validationMessage + ' - Password is missing\r\n';
document.getElementById('errorPasswordMissing').style.display = 'block';
valid = false;
} else {
document.getElementById('errorPasswordMissing').style.display = 'none';
}
if (valid == false) {
alert(validationMessage);
}
return valid;
}
please some one help in validating the login page with errors on not providing any input(it should display respective error message).
Thanks in advance

In the JavaScript
document.getElementById('uname').value
returns "Enter Username…" that is the default value and
document.getElementById('uname').value.length
returns 15 that's why the condition is not matched.
You have to check for default value along with length.
document.getElementById('uname').value = 'Enter Username…'
But once this field is focused the value is empty and it works fine.

your code provide null pointer exception here
document.getElementById('errorPassWordMissing').style.display = '';
exception raise and your function does not return false and form post data.
use placeholder property instead of value and focus event, for example
<input type="password" name="txtPassword" id="pass" placeholder="Enter password…" />
also may be you should use jQuery and validation plugin
http://plugins.jquery.com/validate/

One obvious problem I can see. This is wrong:
document.getElementById('errorUserNameMissing').style.display = '';
You shouldn't be setting style.display to a blank string. It should be one of the standard CSS display types, like "inline" or "block" (and there are other types).

What is wrong with this tabbed content?

I have a google map and a contact form on my contact.html file. They were displayed block as default. I wanted to change it to a tabbed look.
Let's say i have a code like this in HTML:
<div id="tab-group" class="tab-group">
<h3 class="tab-header activate" id="tab-header-1">We are here</h3>
<div class="tab-content activate" id="tab-content-1"></div>
<h3 class="tab-header" id="tab-header-2">Contact us</h3>
<div class="tab-content" id="tab-content-2">
The content in that div with the id="tab-content-1" , I have a google map with the necessary script in the head. And in div with the id="tab-content-2", I have a contact form like;
<form class="tab-content-2" method="post" action="contact-post.html">
<div>
<span><label>NAME</label></span>
<span><input name="userName" type="text" class="textbox"></span>
</div>
<div>
<span><label>E-MAIL</label></span>
<span><input name="userEmail" type="text" class="textbox"></span>
</div>
<div>
<span><label>PHONE</label></span>
<span><input name="userPhone" type="text" class="textbox"></span>
</div>
<div>
<span><label>YOUR MESSAGE</label></span>
<span><textarea name="userMsg"> </textarea></span>
</div>
<div>
<span><input type="submit" value="Send me"></span>
</div>
</form>
Here is the JavaScript:
"use strict";
document.addEventListener('DOMContentLoaded', function() {
document.getElementById('tab-group').className = 'activate';
var headerClass = 'tab-header',
contentClass = 'tab-content';
document.getElementById('tab-group').addEventListener('click', function(event) {
var myHeader = event.target;
if (myHeader.className !== headerClass) return;
var myID = myHeader.id, // e.g. tab-header-1
contentID = myID.replace('header', 'content'); // result: tab-content-1
deactivateAllTabs();
myHeader.className = headerClass + ' activate';
document.getElementById(contentID).className = contentClass + ' activate';
});
function deactivateAllTabs() {
var tabHeaders = document.getElementsByClassName(headerClass),
tabContents = document.getElementsByClassName(contentClass);
for (var i = 0; i < tabHeaders.length; i++) {
tabHeaders[i].className = headerClass;
tabContents[i].className = contentClass;
}
}
});
I know I have to clean all these up but i am lost in such a basic thing and getting angry, here is the CSS:
#tab-group h3 {
text-align: left;
text-shadow: 0 1px 0 #161616;
font-family: 'Julius Sans One', sans-serif;
font-size: 1.8em;
color: #FFD955;
padding-bottom: 20px;
}
.activate {
position: relative;
margin-bottom: 2em;
}
#tab-group.activate .tab-header {
font-weight: normal;
font-size: 13px;
text-transform: uppercase;
padding: 4px 6px;
display:inline;
}
.activate .tab-header {
position: absolute;
top: 0;
margin: 0;
padding: 0.25em 0.5em;
left: 0;
background: rgba(168, 161, 152, 0.34);
border: 1px solid #161616;
border-radius: 4px 4px 0 0;
z-index: 2;
cursor: pointer;
}
.activate .tab-header.activate {
background: #000;
}
.activate .tab-content {
position: relative;
top: 0;
margin: 0;
padding: 0.5em;
top: 24px;
border: 1px solid #999;
z-index: 1;
background: white;
zoom: 1;
}
.activate .tab-content:after {
display: block;
height: 0;
clear: both;
visibility: hidden;
}
.activate #tab-header-2 {
left: 9em;
}
.activate .tab-content {
}
.activate .tab-content:active {
display: block;
}
#tab-content-1 {
width: 56.4em;
height:30em;
}
#tab-header-1 {
text-shadow: 0 1px 0 #161616;
font-family: 'Julius Sans One', sans-serif;
font-size: 1.8em;
color: #FFD955;
padding-bottom: 20px;
}
#tab-header-2 {
text-shadow: 0 1px 0 #161616;
font-family: 'Julius Sans One', sans-serif;
font-size: 1.8em;
color: #FFD955;
padding-bottom: 20px;
}
#tab-content-2{
position:relative;
padding-bottom:30px;
background-color:#000;
}
I want it to act like a simple tabbed content. Yet, the contents of the tabs are displayed as block and it doesn't change the content when you click on h3 tab-headers.
it looks like this.....
What am I doing wrong ? Thanks in advance...

It should just be a simple fix. Try adding:
.activate .tab-content { display: none; }
.activate .tab-content.activate { display: block; }
That way, only the active tab is visible, and the others are hidden.

A few points:
Your HTML is invalid, you should something like the W3C Validator to check your HTML.
You element names and ids are inconsistent. E.g. Your "Name" field is named "txtName" but has the id "name" and your "E-mail address" field is named "FieldData1" but has the id "FieldData2". Use consistent and sensible names so that the HTML and JavaScript are easy to write and understand.
You've broken the JavaScript by removing the AND operators (&&) in the checkForm function. The showErrorAndFocusIf function returns a boolean value that is true when the specified field is valid. The return values of the calls are supposed to be combined for all of the validation constraints to determine if the whole form has passed validation.
Lastly, the ids of the fields and error messages used in the JavaScript did not match the HTML. The JavaScript uses the DOM's getElementById function to retrieve references to the fields and the error messages in the HTML, so you have to make sure that the ids match in order for the code to work.
