HTML - Input text pattern/required attributes conflict with submission

This simple form is part of a larger web app I have created. Both the required attributes and the pattern attributes only work intermittently. Changing the event listener to "submit" rather than "click" makes the form validation work properly, but then I get a blank page when I submit with the proper input formatting.
var v = "userForm"
document.getElementById("clockIn").addEventListener("click", addLine); //CHANGE TO CLICK FOR WORKING PAGE BUT PATTERN WONT WORK
function addLine() {
//e.preventDefault();
var firstName = document.getElementById("fname").value;
var lastName = document.getElementById("lname").value;
var jobNumber = document.getElementById("jnum").value;
var process = document.querySelector('input[name="operation"]:checked').value;
var comment = document.getElementById("comment").value;
var timeIn = new Date().toLocaleString();
var info = [firstName, lastName, jobNumber, process, timeIn, comment];
google.script.run.addEntry(info);
document.getElementById("fname").value = "";
document.getElementById("lname").value = "";
document.getElementById("jnum").value = "";
document.getElementById("comment").value = "";
document.querySelector('input[name="operation"]:checked').checked = false;
alert("Submitted");
}
function addEntry(info) {
var ssid = "1E81r5Xy**********************W1o4Q";
var ss = SpreadsheetApp.openById(ssid);
var oj = ss.getSheetByName("Open Jobs");
var FileIterator = DriveApp.getFilesByName("Drawings & Links");
while (FileIterator.hasNext()) {
var file = FileIterator.next();
if (file.getName() == "Drawings & Links") {
// var Sheet = SpreadsheetApp.open(file);
var dlid = file.getId();
}
}
var drawingLinks = SpreadsheetApp.openById(dlid);
var dl = drawingLinks.getSheetByName("Sheet1");
Logger.log(dlid)
oj.appendRow(info);
}

Thanks for the help.
I think I have narrowed the problem down to something to do with the event listener. My thought is that when the "click" event is used, the function runs before the fields are validated by the browser. Yet, I just get a blank page if I use the "submit" event. The function "addEntry" doesn't appear to run; the logged data doesn't appear. Same goes for "addLine" when I add an alert. I have isolated the regex code and verified it works as expected.
Edit: I found that when I remove the event listener on the submit button and add an onsubmit (onsubmit="addLine()") attribute to the form, the alert in "addLine" appears. The "Submitted" alert also appears. Still a blank page after.

Your validation fails but that is outside the scope of the question as I see it since you need to check the actual values before you let it submit and probably need a preventDefault() on the form if any fail.
You get an error because you cannot filter by :checked unless you then determine if that is null OR filter it after you get the nodeList.
Here I show a couple of ways to handle the radio buttons; up to you to determine which suits you.
var v = "userForm"
document.getElementById("clockIn").addEventListener("click", addLine); //CHANGE TO CLICK FOR WORKING PAGE BUT PATTERN WONT WORK
function addLine() {
//e.preventDefault();
var firstName = document.getElementById("fname").value;
var lastName = document.getElementById("lname").value;
var jobNumber = document.getElementById("jnum").value;
//demonstrate a few ways to hanlde the radio buttons:
const procOne = document.querySelector('input[name="operation"]:checked');
console.log(!!procOne ? procOne.value : procOne, typeof procOne); // null and object if none are checked
let processValue = procOne === null && typeof procOne === "object" ? "" : procOne.value;
// querySelectorAll to get all of them so we can filter the list
const processAll = document.querySelectorAll('input[name="operation"]');
// creates an array like object of the nodelist; then filters it for checked ones
const checkProcess = [...processAll].filter(item => item.checked);
console.log("How many?:", processAll.length);
console.log("How many checked?:", checkProcess.length);
console.log(checkProcess.length ? checkProcess.value : "nothing");
// anther way to get value:
processValue = checkProcess.length ? checkProcess.value : "nothing"
if (checkProcess.length !== 0) { //Test if something was checked
console.log(checkProcess.value); // the value of the checked.
} else {
console.log('Nothing checked'); // nothing was checked.
}
var comment = document.getElementById("comment").value;
var timeIn = new Date().toLocaleString();
let process = processValue;
var info = [firstName, lastName, jobNumber, process, timeIn, comment];
//ccommented out as google is not defined
//google.script.run.addEntry(info);
// hitting the DOM again is not a great thing here but left as not part of the question/issue
document.getElementById("fname").value = "";
document.getElementById("lname").value = "";
document.getElementById("jnum").value = "";
document.getElementById("comment").value = "";
// cannot filter by :checked if none are so check first and set to false
if (procOne != null) procOne.checked = false;
alert("Submitted");
}
function addEntry(info) {
var ssid = "1E81r5Xy**********************W1o4Q";
var ss = SpreadsheetApp.openById(ssid);

Launching a new window and filling form values using Javascript

I have been learning JavaScript and i am attempting to launch a new window on click after a user has placed info into a form fields and then placing that info into form fields in the newly launched window. I have read many posts and methods in Stackoverflow however i cant seem to get it to work properly.
Starting page HTML:
<form id="memCat" methed="get" class="member_catalogue">
<button type="submit" class="prodBtn" id="catOrder" onclick="openMemberOrder()"><img class="prodImg" src="../../../Images/bcpot002_thumb.jpg" name="Red Bowl"></button>
<div class="cat_block">
<label class="cat_label" for="cat_name">Product Name:</label>
<input class="cat_input" type="text" id="catID" value="bepot002" readonly>
</div>
<div class="cat_block">
<label class="cat_label" for="cat_description">Product Description:</label>
<input class="cat_input" type="text" id="catDesc" value="Ocre Red Pot" readonly>
</div>
<div class="cat_block">
<label class="cat_label" for="cat_price">Per unit price:$</label>
<input class="cat_input" type="number" id="catVal" value="10" readonly>
</div>
</form>
New page HTML:
<form id="memOrder" method="post">
<div>
<label for="pname">Product Name:</label>
<input type="text" id="orderID" readonly>
</div>
<div>
<label for="pdescription">Product Description:</label>
<input type="text" id="orderDesc" readonly>
</div>
<div>
<label for="quantity">Quantity ordered:</label>
<input type="number" class="quantOrder" id="orderOrder" value="1" min="1" max="10">
</div>
<div>
<label for="ind_price">Per unit price: $</label>
<input type="number" class="quantCount" id="orderVal" readonly>
</div>
<div>
<label for="tot_price">Total Price: $</label>
<input type="number" class="quantCount" id="orderTotal" readonly>
</div>
<div>
<button type="reset">Clear Order</button>
<button type="submit" id="orderCalc">Calculate Total</button>
<button type="submit" id="orderPlace">Place Order</button>
</div>
</form>
Script i have to date:
function openMemberOrder() {
document.getElementById("orderID").value = document.getElementById("catID").document.getElementsByTagName("value");
document.getElementById("orderDesc").value = document.getElementById("catDesc").document.getElementsByTagName("value");
document.getElementById("orderVal").value = document.getElementById("catVal").document.getElementsByTagName("value");
memberOrderWindow = window.open('Member_Orders/members_order.html','_blank','width=1000,height=1000');
};
script and other meta tags in head are correct as other code is working correctly.

So after much trial and error i have had success with this:
On the submission page:
1. I created a button on the page that will capture the input form data
2. i created the localstorage function in JS
3. I then placed the script tag at the bottom of the page before the closing body tag
HTML
<button type="submit" class="prodBtn" id="catOrder" onclick="openMemberOrder()"><img class="prodImg" src="../../../Images/bcpot002/bcpot002_thumb.jpg" name="Red Bowl"></button>
Javascript
var catID = document.getElementById("catID").value;
var catDesc = document.getElementById("catDesc").value;
var catVal = document.getElementById("catVal").value;
function openMemberOrder() {
var memberOrderWindow;
localStorage.setItem("catID", document.getElementById("catID").value);
localStorage.setItem("catDesc", document.getElementById("catDesc").value);
localStorage.setItem("catVal", document.getElementById("catVal").value);
memberOrderWindow = window.open('Member_Orders/members_order.html', '_blank', 'width=1240px,height=1050px,toolbar=no,scrollbars=no,resizable=no');
} ;
Script Tag
<script type="text/javascript" src="../../../JS/catOrder.js"></script>
I then created the new page with the following javascript in the header loading both an image grid as well as input element values:
var urlArray = [];
var urlStart = '<img src=\'../../../../Images/';
var urlMid = '_r';
var urlEnd = '.jpg\'>';
var ID = localStorage.getItem('catID');
for (var rowN=1; rowN<5; rowN++) {
for (var colN = 1; colN < 6; colN++){
urlArray.push(urlStart + ID + '/' + ID + urlMid + rowN + '_c' + colN + urlEnd)
}
}
window.onload = function urlLoad(){
document.getElementById('gridContainer').innerHTML = urlArray;
document.getElementById('orderID').setAttribute('value', localStorage.getItem('catID'));
document.getElementById('orderDesc').setAttribute('value', localStorage.getItem('catDesc'));
document.getElementById('orderVal').setAttribute('value', localStorage.getItem('catVal'));
};
I then created 2 buttons to calculate a total based on inputs and clearing values separately, the script for this was placed at the bottom of the page.
function total() {
var Quantity = document.getElementById('orderQuant').value;
var Value = document.getElementById('orderVal').value;
var Total = Quantity * Value;
document.getElementById('orderTotal').value = Total;
}
function clearForm() {
var i = 0;
var j = 0;
document.getElementById('orderQuant').value = i;
document.getElementById('orderTotal').value = j;
}

Using DOM to create an input

I currently have been working on this code and I can't seem to figure it out. I am planning to make it so that if the radio button is pressed that shipping is not free, that an input field pops up to specifying what the addition cost will be using DOM. I am also trying to figure out how to add text to describe the input field, and to validate the input field.
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<script>
function myFunction() {
var x = document.createElement("INPUT");
var c = 1;
if (c = 1) {
x.setAttribute("type", "text");
var sp2 = document.getElementById("emailP");
// var br = document.createElement("br");
// sp2.appendChild(br);
// alert("added break");
var sp2 = document.getElementById("emailP");
var parentDiv = sp2.parentNode;
parentDiv.insertBefore(x, sp2);
c++;
alert("Added Text Box");
}
}
</script>
<form action="#" method="post" onsubmit="alert('Your form has been submitted.'); return false;">
<p class="boldParagraph">Upload an Image:</p>
<input type="file" id="pic" accept="image/*" required>
<p class="boldParagraph">Name of seller:</p>
<input class="averageTextBox" type="text" id="seller" value="" required>
<p class="boldParagraph" id = "tip3P">Shipping costs are free:</p>
<input type="radio" name="tip3" value="3" checked /> Yes
<input type="radio" name="tip3" value="4" onclick="myFunction(); this.onclick=null;"/> No
<p class="boldParagraph" id = "emailP">Email of seller:</p>
<input class="averageTextBox" type="email" id="emailAddress" value="" required>
<p class="boldParagraph">Closing date for auction:</p>
<input type="date" id="closeDate" value="" required>
<br><br>
<button>Submit</button>
</form>
</body>
</html>

Create a label element and populate text using innerHTML. and then append to DOM.
Example Snippet:
function myFunction() {
var label = document.createElement("label");
label.innerHTML = "<br>Shipment Cost : ";
var x = document.createElement("INPUT");
var c = 1;
if (c = 1) {
x.setAttribute("type", "text");
var sp2 = document.getElementById("emailP");
// var br = document.createElement("br");
// sp2.appendChild(br);
// alert("added break");
var sp2 = document.getElementById("emailP");
var parentDiv = sp2.parentNode;
parentDiv.insertBefore(x, sp2);
parentDiv.insertBefore(label, x);
c++;
alert("Added Text Box");
}
}
<form action="#" method="post" onsubmit="alert('Your form has been submitted.'); return false;">
<p class="boldParagraph">Upload an Image:</p>
<input type="file" id="pic" accept="image/*" required>
<p class="boldParagraph">Name of seller:</p>
<input class="averageTextBox" type="text" id="seller" value="" required>
<p class="boldParagraph" id="tip3P">Shipping costs are free:</p>
<input type="radio" name="tip3" value="3" checked />Yes
<input type="radio" name="tip3" value="4" onclick="myFunction(); this.onclick=null;" />No
<p class="boldParagraph" id="emailP">Email of seller:</p>
<input class="averageTextBox" type="email" id="emailAddress" value="" required>
<p class="boldParagraph">Closing date for auction:</p>
<input type="date" id="closeDate" value="" required>
<br>
<br>
<button>Submit</button>
</form>
OR
You can keep the text box hidden and show it when user clicks no. Also, apply validations only when no is selected for shipment radio button.
I suggest use jQuery, see the snippet below:
jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript.
var radioButtons = $("[name=tip3]");
radioButtons.on("change", function() {
if ($("[name=tip3]:checked").val() == "3") {
$("#shipmentDetail").hide();
} else {
$("#shipmentDetail").show();
}
})
$("#submit").on("click", function() {
var flag = true;
if ($("[name=tip3]:checked").val() == "4") {
if ($("#shipmentDetail").val() == "") {
flag = false;
alert("enter some value");
}
}
//other validations here
if (flag) {
$("#form").submit()
}
})
#shipmentDetail {
display: none
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="form" action="#" method="post">
<p class="boldParagraph">Upload an Image:</p>
<input type="file" id="pic" accept="image/*" required>
<p class="boldParagraph">Name of seller:</p>
<input class="averageTextBox" type="text" id="seller" value="" required>
<p class="boldParagraph" id="tip3P">Shipping costs are free:</p>
<input type="radio" name="tip3" value="3" checked />Yes
<input type="radio" name="tip3" value="4" />No
<label id="shipmentDetail" for="price">Shipment Cost:
<input id="price" type="text" value="" />
</label>
<p class="boldParagraph" id="emailP">Email of seller:</p>
<input class="averageTextBox" type="email" id="emailAddress" value="" required>
<p class="boldParagraph">Closing date for auction:</p>
<input type="date" id="closeDate" value="" required>
<br>
<br>
<button id="submit">Submit</button>
</form>

replace
alert("Added Text Box");
with:
var additional_fees = prompt("Type in");
x.setAttribute("value", additional_fees)

Save dynamically generated input fields

I am using this code to generate dynamically ADD More input fields and then plan on using Save button to save their values in database. The challenge is that on Save button, I want to keep displaying the User Generated Input fields. However they are being refreshed on Save button clicked.
javascript:
<script type="text/javascript">
var rowNum = 0;
function addRow(frm) {
rowNum++;
var row = '<p id="rowNum' + rowNum + '">Item quantity: <input type="text" name="qty[]" size="4" value="' + frm.add_qty.value + '"> Item name: <input type="text" name="name[]" value="' + frm.add_name.value + '"> <input type="button" value="Remove" onclick="removeRow(' + rowNum + ');"></p>';
jQuery('#itemRows').append(row);
frm.add_qty.value = '';
frm.add_name.value = '';
}
function removeRow(rnum) {
jQuery('#rowNum' + rnum).remove();
}
</script>
HTML:
<form method="post">
<div id="itemRows">Item quantity:
<input type="text" name="add_qty" size="4" />Item name:
<input type="text" name="add_name" />
<input onclick="addRow(this.form);" type="button" value="Add row" />
</div>
<p>
<button id="_save">Save by grabbing html</button>
<br>
</p>
</form>

One approach is to define a template to add it dynamically via jQuery
Template
<script type="text/html" id="form_tpl">
<div class = "control-group" >
<label class = "control-label"for = 'emp_name' > Employer Name </label>
<div class="controls">
<input type="text" name="work_emp_name[<%= element.i %>]" class="work_emp_name"
value="" />
</div>
</div>
Button click event
$("form").on("click", ".add_employer", function (e) {
e.preventDefault();
var tplData = {
i: counter
};
$("#word_exp_area").append(tpl(tplData));
counter += 1;
});
The main thing is to call e.preventDefault(); to prevent the page from reload.

have your form call an upate.php file, targeting an iframe of 1px.

JQuery ignoring form element

I have this JQuery:
$(document).ready(function() {
$("#generate").click(function() {
var texts = [];
alert();
$("form label").each(function() {
var oLabel = $(this);
var oInput = oLabel.next();
texts.push(oLabel.text() + " " + oInput.val());
});
texts[0] += texts[1];
texts[2] += texts[3];
for(i=3;i<texts.length;i++)
texts[i-1] = texts[i];
texts[texts.length-1] = null;
$("#cont").html(texts.join("<br />"));
});
});
What it do is it reads form elements then types them as regular text (there is a purpose for this).
And this is how my form looks like ...
<div id="cont" style="float:right; width:75%; height:auto">
<form onSubmit="return generate();">
<label class="itemLabel" for="name">Name : </label>
<input name="name" type="text" class="itemInput" value="<? echo $queryB[1]; ?>" readonly="readonly" />
<label># Some Text</label><br />
<label for="priPhone" class="itemLabel">Customer Telephone Number : </label>Phone#
<input name="priPhone" type="text" class="itemInput" readonly="readonly" value="<? echo $queryB[2]; ?>" />
<label for="secPhone"> // Mobile#</label>
<input name="secPhone" type="text" class="itemInput" readonly="readonly" value="<? echo $queryB[3]; ?>" /><br />
<label class="itemLabel" for="email">Customer Email Address : </label>
<input name="email" type="text" class="itemInput" readonly="readonly" value="<? echo $queryB[4]; ?>" /><br />
<label>***************</label><br />
<label>Best Regards,</label><br />
<input name="another_field" type="text" /><br />
<label>last thing</label><br />
<button type="button" id="generate">Generate</button>
</form>
</div>
now, when I click the button "Generate", everything goes well except that it ignores "another_field" and doesn't get its value
Anyone got an idea to solve this? (Note: This piece of code will be running on around 25 forms so I need to have it working.)
UPDATE:
Sample output:
Name : username # Some Text
Customer Telephone Number : 90237590 // 3298579
Customer Email Address : email#host.com
***************
Best Regards,
last_field
last thing
Workaround
Since I'm having all the forms have the same ending, I've been able to get to this code:
texts[0] += " " + texts[1];
texts[1] = texts[2] + " " + texts[3];
for(i=4;i<texts.length;i++)
texts[i-2] = texts[i];
texts[texts.length-2] = texts[texts.length-3];
texts[texts.length-3] = $("#agent").val() ;
texts[texts.length-1] = null;
It solved the problem, but I'm looking for a better way to accomplish this.

Try this javascript:
$(document).ready(function() {
$("#generate").click(function() {
var texts = [];
$("form").children().each(function() {
var el = $(this);
if (el.prop('tagName') == "LABEL") texts.push(el.text());
if (el.prop('tagName') == "INPUT") texts.push(el.val());
if (el.prop('tagName') == "BR") texts.push("<br />");
});
$("#cont").html(texts.join(""));
});
});
Working example here:
http://jsfiddle.net/Q5AD4/6/

Your <br/> tag is the next tag after the label before "another_field". You should probably make your next call something like:
var oInput = oLabel.next('input');
