How to append an inline template element with modified (id) content to another element?

Below in the example, I want that each time when the add button is clicked to take the element inside the template div and append it to the landingzone class element. But at the same time I need the NEWID to change for the new element. Of course this is just an example, the table stuff can be a div or anything else.
the form:
<form method="post">
<input type="text" name="title">
<input type="text" name="number">
<table>
<thead>
<tr> <th>Parts</th> </tr>
</thead>
<tbody class="landingzone">
</tbody>
</table>
<input type="submit" value="Save">
<input type="button" name"add" class="add" value="Save">
</form>
the template:
<div class="template" style="display: hidden">
<tr id="NEWID">
<td>
<input type="text" name="part_NEWID">
</td>
</tr>
</div>
What would be the best way to accomplish this?

Here's an example for your need. The javascript will work without changing any html except in place of name"add" should be name="add"
What i have done here is i'm getting the id of the template tr and setting it with increment and also the input field name.
var $landingzone = $('.landingzone');
var $add = $('.add');
var desiredId = 'id';
$add.on('click', function() {
var $template = $('.template').find('tr');
var id = $template.attr('id');
var idArr = id.split('-');
if (!idArr[1]) {
id = desiredId + '-1';
} else {
id = desiredId + '-' + (parseInt(idArr[1]) + 1);
}
$template.attr('id', id);
$template.find('input').attr('name', 'part_'+id);
console.log('input id--->'+id, 'input name--->'+'part_'+id);
$landingzone.append($template.clone());
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form method="post">
<input type="text" name="title">
<input type="text" name="number">
<table>
<thead>
<tr>
<th>Parts</th>
</tr>
</thead>
<tbody class="landingzone">
</tbody>
</table>
<input type="submit" value="Save">
<input type="button" name="add" class="add" value="Add">
</form>
<table class="template" style="display: none">
<tr id="NEWID">
<td>
<input type="text" name="part_NEWID">
</td>
</tr>
</table>

Like #Andrea said in her comment, some more details would be appreciated ...
I think what you are after is:
const $template = $('.template').clone()
$template.attr('id', 'someId')
$template.find('input[name="part_NEWID"]').attr('name', 'part_someId')
$('.landingzone').append($template)
And if you need it in a function:
function appendTemplateToLandingZone (newId) {
const $template = $('.template').clone()
$template.attr('id', newId)
$template.find('input[name="part_NEWID"]').attr('name', 'part_' + newId)
$('.landingzone').append($template)
}
I haven't tested this, so it might need a slight adjustment. If you'll provide a basic jsbin I'll make it work there.

HTML Table - Iterate over row and sum the fields

I have then following table:
<table style="width:100%" id="testTable">
<tr>
<th>length per</th>
<th>width per</th>
<th>length</th>
<th>width</th>
<th>total</th>
</tr>
<tr align='right'>
<td>
<input type="text" name="length-per-input">
</td>
<td>
<input type="text" name="width-per-input">
</td>
<td>
<input type="text" name="length-total-input">
</td>
<td>
<input type="text" name="width-total-input">
</td>
<td>
<input type="text" name="total-output" disabled="disabled">
</td>
</tr>
<tr align='right'>
<td>
<input type="text" name="length-per-input">
</td>
<td>
<input type="text" name="width-per-input">
</td>
<td>
<input type="text" name="length-total-input">
</td>
<td>
<input type="text" name="width-total-input">
</td>
<td>
<input type="text" name="total-output" disabled="disabled">
</td>
</tr>
</table>
<input type=button value='+' onclick="addRow()" />
<input type=button value='Calculate' onclick="Calculate()" />
I also have the javascript which adds the value and puts it in total:
<script>
function Calculate() {
var lengthPerInput = $("input[name='length-per-input']").val();
var widthPerInput = $("input[name='width-per-input']").val();
var lengthTotal = $("input[name='length-total-input']").val();
var widthTotal = $("input[name='width-total-input']").val();
var total = (lengthTotal/lengthPerInput) + (widthTotal/widthPerInput);
$("input[name='total-output']").val(total);
}
</script>
The aim here is to have it iterate over the two rows, then add each one separately.
I know how to get each row by using:
$('#testTable tr').each(function(){
console.log(this);
$(this).find('length-per-input').each(function(){
console.log(this);
})
})
But using the row (accessed via "this") I don't know how to get the correct cells, get their value, then perform the calculate on that row for the total.
Any advice on this please? Thank you!

function Calculate(tr_row) {
var lengthPerInput = tr_row.find("input[name='length-per-input']").val();
var widthPerInput = tr_row.find("input[name='width-per-input']").val();
var lengthTotal = tr_row.find("input[name='length-total-input']").val();
var widthTotal = tr_row.find("input[name='width-total-input']").val();
var total = (lengthTotal/lengthPerInput) + (widthTotal/widthPerInput);
tr_row.find("input[name='total-output']").val(total);
}
For every row you call function to summ the values
To the function you pass the row, then it can collect values on that row
$('#testTable tr').each(function(){
Calculate($(this))
})

You can use each() function to iterate through table and use find() function to find cell values.
function Calculate() {
$('#testTable tr').each(function() {
var lengthPerInput = $(this).find("input[name='length-per-input']").val();
var widthPerInput = $(this).find("input[name='width-per-input']").val();
var lengthTotal = $(this).find("input[name='length-total-input']").val();
var widthTotal = $(this).find("input[name='width-total-input']").val();
var total = (lengthTotal/lengthPerInput) + (widthTotal/widthPerInput);
$(this).find("input[name='total-output']").val(total);
});
}

When I press the submit button I expected that some words beside the first textbox will disappear, but nothing happened. Can some one explain to me where the problem is?

You have not properly defined your script tag. Proper value will be text/javascript.
<script type="text/javascript">
instead of
<script type="javascript">

Your js code is correct but you have to change that
<script type="javascript"> as <script type="text/javascript">
See your code here its working perfectly in jsfiddle
http://jsfiddle.net/WxtJ3/

<script type="text/javascript">
and change
<button type = "submit" onClick = "d();">
to
<button type = "button" onClick = "d();">
or else your page gonna be reloading

JavaScript will not calculate and input my results back into my form

Trying to pull information from my form input fields and calculate them using JavaScript. It does not seem to be working.
HTML (default1.html)
<script type="text/javascript" src="multiplication.js" language="javascript"></script>
<form>
<table>
<tr><!--Row 2-->
<td class="tdSize7">
<input class="input" name="name1" type="text"/>
</td>
<td class="tdSize7">
<input class="input" name="source1" type="text"/>
</td>
<td class="tdSize8">
<p>$</p>
</td>
<td class="tdSize9">
<input class="input" name="income1" type="text"/>
</td>
<td class="tdSize8">
<p>X12</p>
</td>
<td class="tdSize8">
<p>$</p>
</td>
<td class="tdSize9">
<input name="ann1" disabled="disabled"/>
</td>
</tr>
<td class="tdSize9"><input class="inputSize2" name="" type="button" value="Calculate" onclick="addme(this.form)"/></td>
</table>
</form>
JavaScript (multiplication.js)
function addme(form) {
//Constant Variables
const twelve = Number (12);
const fourHun = Number (400);
const fourHunEighty = Number (480);
//Monthly Income 1
var income1 = Number(frm.income1.value);
var val = income1 * twelve;
frm.ann1.value = val;
}
My JavaScript will not calculate and input my results back into my form.
This is just a sample of my code. I am hoping this will tell you enough and help you, in helping me fixing my problem.

Did you intend to use form instead of frm? That is part of your problem
Try:
var income1 = Number(form.income1.value);
var val = income1 * twelve;
form.ann1.value = val;
Or change
function addme(form)
to
function addme(frm)

javascript window redirect doesn't fire up

This problem seems to be odd to me and I can't seem to fix it. I do have a simple HTML form; inside, I do have a textbox and a button as shown down here:
<form id="form1" method="get"> <!-- Note: No Action property -->
<div>
<h1>
Simple Test Form</h1>
<table border="0" width="400">
<tr>
<td align="right">
All of these words
</td>
<td>
<input name="txtAll" id="txtAll" type="text" value="testing keyword" />
</td>
</tr>
<tr>
<td colspan="2" align="center">
<input type="submit" name="Submit" value="Submit" onclick="myJS(this);" />
</td>
</tr>
</table>
</div>
</form>
MyJS file is as:
<script type="text/javascript">
function myJS(which) {
var CONSTANT_SITE_TARGET = "http://servername/redirect/target.aspx?text=";
//capture all values from the form
var allWords = document.getElementById("txtAll").value;
var morestring = ""; //More data manipulation here.....
var url = CONSTANT_SITE_TARGET + allWords + morestring;
window.open(url);
//window.location = url; //Doesn't work
//window.location.href = url; //Doesn't work
//self.location = url; //Doesn't work
//top.location = url; //Doesn't work
}
</script>
As you can see, it doesn't redirect to the designated URL in the javascript. When I use the window.open then it works. Note that in the < form... > tag, I don't put the action property in it. I don't want to open a new browser, just redirect to the new url within the same browser.
Is there a way to redirect it?

Don't use the form tags. Or, set the "type" attribute of your button to be "button", not "submit". The form submits when you click the button, but you don't want that to happen. Either removing the form or changing the button should fix improper redirection. When you don't specify an action, I'm pretty sure the default is the current URL.

Ok, just an idea. As you haven't set the action parameter, the default behaviour of a submit button is to reload the same page. You alter that behaviour by handling its onclick. Maybe there is a conflict that can be resolved by having return false; at the end of the click handler, which prevents the default action for that event.

Here
function myJS(which) {
var CONSTANT_SITE_TARGET = "http://servername/redirect/target.aspx?text=";
//capture all values from the form
var allWords = which.txtAll.value;
var morestring = ""; //More data manipulation here.....
return CONSTANT_SITE_TARGET + allWords + morestring;
}
<form id="form1" method="get" onsubmit="this.action=myJs(this)">
<div>
<h1>
Simple Test Form</h1>
<table border="0" width="400">
<tr>
<td align="right">
All of these words
</td>

<input name="txtAll" id="txtAll" type="text" value="testing keyword" />
</td>
</tr>
<tr>
<td colspan="2" align="center">
<input type="submit" name="Submit" value="Submit" />
</td>
</tr>
</table>
</div>
</form>
to elaborate on a comment:
<script>
window.onload=function() {
document.getElementById("Submit").onclick=function() {
var CONSTANT_SITE_TARGET = "http://servername/redirect/target.aspx?text=";
//capture all values from the form
var allWords = document.getElementById("txtAll".value;
var morestring = ""; //More data manipulation here.....
location = CONSTANT_SITE_TARGET + allWords + morestring;
}
}
</script>
<div>
<h1>
Simple Test Form</h1>
<table border="0" width="400">
<tr>
<td align="right">
All of these words
</td>
<td>
<input name="txtAll" id="txtAll" type="text" value="testing keyword" />
</td>
</tr>
<tr>
<td colspan="2" align="center">
<input type="button" id="Submit" value="Submit" />
</td>
</tr>
</table>
</div>

Try one the options for redirection below. I commented out three of them so that the code stays valid, but you may play around with either and see if it suits your needs.
var CONSTANT_SITE_TARGET = "http://servername/redirect/target.aspx?text=";
//capture all values from the form
var allWords = document.getElementById("txtAll").value;
var morestring = ""; //More data manipulation here.....
var url = CONSTANT_SITE_TARGET + allWords + morestring;
window.location.href= url;
//window.navigate(url);
//self.location(url);
//top.location(url);
