Javascript document.getElementById function not returning checkbox value to HTML form

I have been searching for an answer everywhere but just can not find what I need.
I have a webpage that has an HTML table on the left column and an HTML form on the right column. When I click on a row in the table on the left I want it to display the values in the form on the right.
I have this working perfectly for the text fields on the form, but not for the two checkboxes. My javascript will return either true or false or checked and unchecked to the document.getElementById within the script itself by using alert(); but I have no idea what it needs to allow the checkboxes to display these values. I thought the document.getElementById would return the values but it seems it does not.
I have tried all kinds of conveluted ways to get this to work but can not seem to get the correct code needed.
I am new to all this so there is most likely something really simple I am missing.
This is the HTML form code:
<div class="column right">
<table>
<tr></tr>
<tr>
<div class="lockinv">
<form autocomplete="off" name="lockform" class="keyassign" action="includes/lockinventory.inc.php"
method="post">
<label id="inventory" for="locknum">Lock Number</label>
<input id="invlocknum" type="text" name="locknum" value="" required>
<label id="inventory" for="locktype">Lock Type</label>
<input id="invlocktype" type="text" name="locktype" value="" required>
<label id="inventory" for="keycode">Key Code</label>
<input id="invkeycode" type="text" name="keycode" value="" required>
<label id="inventory" for="lockengraved">Lock Engraved</label>
<input id="invlockengraved" type="hidden" name="lockengraved" value="0">
<input id="invlockengraved" type="checkbox" name="lockengraved" value="1">
<label id="inventory" for="lockmastered">Lock Mastered</label>
<input id="invlockmastered" type="hidden" name="lockmastered" value="0">
<input id="invlockmastered" type="checkbox" name="lockmastered" value="1">
<label id="inventory" for="locknote">Lock Note</label>
<textarea id="inventorynote" name="locknote" rows="5" cols="60"></textarea>
<div class="wheel">
<?php
if (isset($_GET["error"])) {
if($_GET["error"] == "lockexists") {
echo "<p>Lock Already In Inventory!</p>";
}
else if ($_GET["error"] == "lockexistsfailed") {
echo "<p>Lock Already In Inventory!</p>";
}
}
?>
</div>
<input id="bt6" type="submit" name="submit" value="Save">
<button id="bt6" type="reset" name="button">Cancel</button>
</form>
</div>
</tr>
</table>
</div>
This is my JavaScript code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js" type="text/javascript"></script>
<script language="javascript"></script>
<script>
$(function () {
$('#lockTable td').click(function () {
var currentRow = $(this).closest("tr");
var locknum = currentRow.find("td:eq(0)").text();
var locktype = currentRow.find("td:eq(1)").text();
var keycode = currentRow.find("td:eq(2)").text();
var engraved = currentRow.find("td:eq(3)").find(":checkbox");
var mastered = currentRow.find("td:eq(4)").find(":checkbox");
var locknote = currentRow.find("td:eq(5)").text();
var lockengraved = engraved.prop("checked");
if (lockengraved === true) {
$grved = "checked";
} else {
$grved = "unchecked";
}
var lockmastered = mastered.prop("checked");
if (lockmastered === true) {
$msted = "checked";
} else {
$msted = "unchecked";
}
document.getElementById('invlocknum').value = locknum;
document.getElementById('invlocktype').value = locktype;
document.getElementById('invkeycode').value = keycode;
document.getElementById("invlockengraved").value = $grved;
document.getElementById('invlockmastered').value = $msted;
document.getElementById('inventorynote').value = locknote;
alert(document.getElementById("invlockengraved").value);
alert(document.getElementById("invlockmastered").value);
});
});
</script>
<p id="invlocknum"></p>
<p id="invlocktype"></p>
<p id="invkeycode"></p>
<p id="invlockengraved"></p>
<p id="invlockmastered"></p>
<p id="invlocknote"></p>
<p id="info"></p>
<p id="result"></p>

I found the answer to my issue. I had to modify my if statement in the Javascript to the following. Works the way I want it to. Thanks to all that helped.
var lockengraved = engraved.prop("checked");
if (lockengraved === true) {
document.getElementById("invlockengraved").checked = lockengraved;
}else if (lockengraved === false) {
document.getElementById("invlockengraved").checked = lockengraved;
}

How to make a dropdown autocomplete navigable by keyboard

Here, I have a nice autocomplete dropdown that, given a city typed by the user, the page will show all possible city-state-country triplets. For example the name Guadalajara would suggest
Guadalajara de Buga, Valle del Cauca Department, Colombia
Guadalajara, Castilla La Mancha, Spain
and
Guadalajara, Jalisco, Mexico
The code works perfectly from both the backend and the frontend, the only problem left is that the autosuggest drop down menu will only work with the mouse and not with the keyboard. The Up and Down arrow keys will not allow to navigate through the most appropriate choice and pressing esc doesn't cancel the menu.
I tried everything and I have no idea about what is missing to make this work with the keyboard as well. I would like to find a solution with pure vanilla JavaScript and that would involve the least possible changes in the rest of working code. Here the entire code:

I hope to find the simpler and least invasive solution to complete a code that just have this left.

I would change your dropdown and input to the semantic html datalist element:
<label for="ice-cream-choice">Choose a flavor:</label>
<input list="ice-cream-flavors" id="ice-cream-choice" name="ice-cream-choice" />
<datalist id="ice-cream-flavors">
<option value="Chocolate">
<option value="Coconut">
<option value="Mint">
<option value="Strawberry">
<option value="Vanilla">
</datalist>
Then both search and keyboard accessibility should work more or less out of the box.
If you really don't want to do that, you have to attach event listeners (vanilla js) to the different elements of your dropdown and input field and write a rather long thing to be able to tab or arrow key your way down and up and back into the search field. I would say it's too much work compared to the reward.
Better to use some time to css-animate the datalist so it behaves a bit smoother and style it neatly.

how to add one on name attribute with javascript?

I have a dynamic form section which I need the name attribute to be dynamic as well.
the number should always get +1 each time the user create a new section !
name="training**1**[institut]"
This is crucial to have a proper SQL insert ... otherwise the array won't have a classical database logics !
JSFIDDLE here
Any idea ? thanks a lot from France !
<form method="post" action="">
<!-- INFO SECTION -->
<div id="infos">
<h2>Infos personnelles</h2>
<input placeholder="Prénom">
<input placeholder="Nom">
</div>
<!-- TRAINING SECTION -->
<div id="training">
<h2>Formation</h2>
<!-- Template -->
<div id="new-training" style="display:none">
<div>
</br>
<p></p>
<input id="mytext" type="text" name="training[1][institut]" placeholder="Diplôme" value="">
<input name="training[1][institut]" placeholder="Institut">
</div>
</div>
</div>
<p id="addnew">
+ Ajouter une formation
</p>
<p>
<br>
<input type="submit" value="Sauvergarder" name="submit">
</p>
</form>
<script> // 1st : Enregistrer / supprimer une formation
var ct = 1;
function addTraining()
{
ct++;
var div1 = document.createElement('div');
div1.id = ct;
// link to delete extended form elements
var delLink = 'Supprimer cette formation';
div1.innerHTML = document.getElementById('new-training').innerHTML + delLink;
document.getElementById('training').appendChild(div1);
}
function removeTraining(eleId)
{
d = document;
var ele = d.getElementById(eleId);
var parentEle = d.getElementById('training');
parentEle.removeChild(ele);
}

The best solution (my opinion) is to use a simple templating engine
https://jsfiddle.net/nget5dq2/1/
Addition to your HTML:
<template id="new_el_template" hidden>
<div id="row-{cid}">
<input id="mytext-{cid}" type="text" name="training[{cid}][institut]" placeholder="Diplôme" value="">
<input name="training[{cid}][institut]" placeholder="Institut">
</div>
Supprimer cette formation
</template>
JS
var ct = 1;
function addTraining() {
ct++;
let div = document.createElement('div');
div.innerHTML = document.getElementById('new_el_template').innerHTML.replace(/\{cid\}/gi, ct);
document.getElementById('training').appendChild(div);
}
function removeTraining(eleId) {
document.getElementById('row-' + eleId).parentNode.remove();
}
And yes, you can go ahead and generate the initial element directly from the template.

write the name attribute this way you should get all the data from the form when u post it.
<input id="mytext" type="text" name="training[diploma][]" placeholder="Diplôme" value="">
<input name="training[institut][]" placeholder="Institut">

java script local storage stop working

Newbie here. Using html and Javascript. It was working until I added a side menu. I had it set up with the submit button inside the side menu under the download function. I only included code for the first few questions and answers. The image local storage work sometimes. I'm running it on notepad++ and with chrome.
function save() {
//question1
var question1 = document.getElementById("question1")
var correctanswer1 = document.getElementById("correctanswer1");

Credit Card Swipe in Javascript not working

I am using Javascript to get the credit card information from Magentic Strip Reader device. (I am using USB attached device)
I have written a code in HTML Javascript but it failed to run. I mean my page is on HTTPS when I connected the device after opening this page. The device lights turns to green which means this page is security proof.
But when I swipe the card it did not show nothing in the field. I also have a function to focus on the field. But I don't know whats wrong it, Please see my code below and give me any suggestions.
HTML:
<span style='required'>*</span> - Indicates required field.
<div class='fields'>Swiped Information</div>
<input type=text name='swiped' id='swiped'>
<div class='fields'>First Name</div>
<input type=text name='first_name' id='first_name'><span style='required'>*</span>
</div>
<div class='fields'>Last Name</div>
<input type=text name='last_name' id='last_name'><span style='required'>*</span>
</div>
<div class='fields'>Expiration</div>
<input type=text size=8 name='expiration' id='expiration'><span style='required'>*</span>(MMYY)
</div>
<div class='fields'>CVV Code</div>
<input type=text size=8 name='cvv' id='cvv'><span style='required'>*</span>
</div>
<div class='fields'>Credit Card Number</div>

<a onclick="readCard();" style="cursor:pointer; color:red;">Swipe Credit Card</a>
</div>
Javascript code:
<script type="text/javascript">
function readCard () {
document.getElementById('swiped').focus();
var card_data = document.getElementById('swiped').value;
if(card_data != ''){
var details1 = card_data.split("^");
var card_number = details1[0];
card_number = card_number.substring(2);
var names = details1[1].split("/");
var first_name = names[1];
var last_name = names[0];
var details2 = details1[2].split(";");
details2 = details2[1].split("=");
var exp_date = details2[1];
exp_date = exp_date.substring(0, exp_date.length - 1);
exp_date = exp_date.substring(2, 3) + "/" + exp_date.substring(0,2);
document.getElementById('card').value = card_number;
document.getElementById('first_name').value = first_name;
document.getElementById('last_name').value = last_name;
document.getElementById('expiration').value = exp_date;
}
}

If the swiper model is IDMB, then it is not encrypted but may be set to HID and not KBE (keyboard emulated). Are you able to swipe into a text editor, notepad? If not, you may be able to switch it from HID to KBE with MagTek's demo application.
