HTML & JavaScript. Trying to target a text input from an adjoining anchor

I have an HTML table. On the table I have an input textbox. Next to it. (appended in the HTML) I have an anchor. All I want the anchor to do (at the moment), is get and set the value in the textbox.
Here is my (abbreviated code) HTML Code:
<tr>
<td class="t-Report-cell" headers="DEPARTMENT">
<input type="text" name="f02" size="20" maxlength="2000" value="" col_name="DEPARTMENT" class="u-TF-item u-TF-item--text" autocomplete="off" />
<td class="t-Report-cell" headers="DESCRIPTION">
<input type="text" name="f03" size="20" maxlength="2000" value="soup" col_name="DESCRIPTION" class="u-TF-item u-TF-item--text" autocomplete="off">
<a href="javascript:get_desc( $(this).closest('tr') );" class="a-Button a-Button--popupLOV">
<span class="a-Icon icon-popup-lov">
<span class="visuallyhidden">List</span>
</span>
</a>
<input type="hidden" id="fcs_0001" name="fcs" value="FB0D0992B787C5475D897B224F1FAE9D7547BC497FADE2E32B252FFAE2F31CE235225E0D645509C8E3576895FB814229B832CBF0BC11DA3F784FDE9BD5ADED86" autocomplete="off">
<input type="hidden" id="fcud_0001" name="fcud" value="U" autocomplete="off" />
</tr>
Notice I have an input type=text name=f03 with a value of "soup" (I've also given it another attribute to try and target it. (col_name="DESCRIPTION")
Then under it, I have an anchor which calls a JavaScript function and passes in the current row.
My simple function does the following:
function get_desc(thisRow) {
console.log(thisRow);
var desc = thisRow.find("input[name='f03']");
console.log(desc);
console.log(desc.val());
console.log(desc.text());
}
So it passes in the current row, looks for the input, then tries to get the value.
I can see on console.log that the correct selector is found, but nothing I do gets the value.
As I say, I have lots of JavaScript code in my app, so I've been staring at this wondering what I'm doing wrong

Some debugging shows that this is the window object when you use <a href="javascript:get_desc(this);", :
function get_desc(link) {
console.log(link === window);
}
click me
If you must use html attributes, then you can use onclick='get_desc(this):
function get_desc(link) {
thisRow = $(link).closest('tr')
var desc = thisRow.find("input[name='f03']");
console.log(desc.val());
}
<table>
<tr>
<td>
<input type="text" name="f03" value="soup">
click me
</td>
</tr>
</table>
Alternatively, embrace jquery events (or vanilla events)
$(".link").click(function() {
thisRow = $(this).closest('tr')
var desc = thisRow.find("input[name='f03']");
console.log(desc.val());
});
<table>
<tr>
<td>
<input type="text" name="f03" value="soup">
<a href="javascript:return false;" class='link'>click me</a>
</td>
</tr>
</table>

I used querySelector instead of find and value property of input.
function get_desc(thisRow) {
console.log(thisRow);
var desc = thisRow.querySelector("input[name='f03']");
console.log(desc.value);
}
<table>
<tr onclick="get_desc(this);">
<td class="t-Report-cell" headers="DEPARTMENT">
<input type="text" name="f02" size="20" maxlength="2000" value="" col_name="DEPARTMENT" class="u-TF-item u-TF-item--text" autocomplete="off" />
<td class="t-Report-cell" headers="DESCRIPTION">
<input type="text" name="f03" size="20" maxlength="2000" value="soup" col_name="DESCRIPTION" class="u-TF-item u-TF-item--text" autocomplete="off">
<a href="#" class="a-Button a-Button--popupLOV">
<span class="a-Icon icon-popup-lov">
<span class="visuallyhidden">List</span>
</span>
</a>
<input type="hidden" id="fcs_0001" name="fcs" value="FB0D0992B787C5475D897B224F1FAE9D7547BC497FADE2E32B252FFAE2F31CE235225E0D645509C8E3576895FB814229B832CBF0BC11DA3F784FDE9BD5ADED86" autocomplete="off">
<input type="hidden" id="fcud_0001" name="fcud" value="U" autocomplete="off" />
</tr>
</table>

instead of href use onClick attribute of anchor.
Try this;
<a href="#" onClick="javascript:get_desc( $(this).closest('tr') );" class="a-Button a-Button--popupLOV">

Get input-field value send to another input-field

I'm trying to copy value from an input field and send it to another onkeyup but it only extracts the value and does not send.
function populateSecondTextBox() {
document.getElementById('cepAddressRouteTransporter').value = document.getElementById('postal_code').value;
}
<form action="transporter/route" method="post" role="form">
<table id="address">
<tr>
<td class="label">Zip code</td>
<td class="wideField">
<input class="field" id="postal_code" name="postal_code" onkeyup="populateSecondTextBox();">
</td>
</tr>
</table>
<div class="input-field col s6">
<i class="material-icons prefix">directions</i>
<input placeholder="Ex: 18214-780" id="cepAddressRouteTransporter" name="cepAddressRouteTransporter" type="text" class="validate">
<label for="cepAddressRouteTransporter">CEP:</label>
</div>
</form>

Replace function in head or in body worked for me.
function populateSecondTextBox() {
document.getElementById('cepAddressRouteTransporter').value =
document.getElementById('postal_code').value;
}
JSFiddle

Do the simplest thing
onkeyup="document.getElementById('cepAddressRouteTransporter').value = this.value;"
Change you onkeyup function call as above.

Cloning a tr and it is appearing at the top instead of at the placement of the tr defined

My tr is defined inside the table tag like this:
<table>
<tr>
<td>
<input type="text" name="customerid">
</td>
</tr>
<tr>
<td>
<div id="stlineitems">
<label for="stlineitems">Item(s)</label>
</td>
<td>
<div class="onlyleft">
<select name="get_Items" id="get_Items" class="selectItemsList" data-rule-required="true" data-msg-required="Choose Item">
<option></option>
</select>
</div>
<div class="moveboxleft">
<input type="text" class="inputwidth form-control rates_input" name="rate_items" data-rule-required="true" data-msg-required="Provide Rate or if not, provide 0 value" />
</div>
<br/>
<div class="nextitem">New Item
</div>
</td>
</tr>
</table>
Now, I am using the following snippet to create the cloned above code, all work but the placement is not right, I want it to be creating underneath the tr tag before this <div class="nextitem"> tag, not sure what I am doing wrong here
$('.createNewItemTag').click(function(){
var obj = $(this).parents('tr').first(),
clonedObj = $(obj[0].outerHTML);
clonedObj.find(".select2-container").remove();
clonedObj.find('.createNewItemTag').remove();
clonedObj.find('td').last().append("<a class='removeItem' href='javascript:void(0)';>Remove</a>");
clonedObj.find(".removeItem").click(function(){
$(this).parents('tr').first().remove();
});
console.log(obj);
obj.parents('table').append(clonedObj);
initSelect2ForNextItem(clonedObj.find(".selectItemsList").first());
});

If I understand your question, you want new cloned <tr> elements to be added BEFORE the element with the "new item" tag.
What we are going to do is utilize jQuery's built in .clone() method instead of doing it ourself. Once we have the cloned object we use your existing code to remove the New Item button and add the Remove button.
After we do that we'll utilize jQuery's .before() method to insert the new, cloned element before the original object. (You could use .after() if you wanted this to be inserted after the original object)
$('.createNewItemTag').click(function(){
var obj = $(this).parents('tr').first();
var clonedObj = obj.clone();
clonedObj.find(".select2-container").remove();
clonedObj.find('.createNewItemTag').remove();
clonedObj.find('td').last().append("<a class='removeItem' href='javascript:void(0)';>Remove</a>");
clonedObj.find(".removeItem").click(function(){
$(this).parents('tr').first().remove();
});
obj.before(clonedObj);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td>
<input type="text" name="customerid">
</td>
</tr>
<tr>
<td>
<div id="stlineitems">
<label for="stlineitems">Item(s)</label>
</div>
</td>
<td>
<div class="onlyleft">
<select name="get_Items" id="get_Items" class="selectItemsList" data-rule-required="true" data-msg-required="Choose Item">
<option></option>
</select>
</div>
<div class="moveboxleft">
<input type="text" class="inputwidth form-control rates_input" name="rate_items" data-rule-required="true" data-msg-required="Provide Rate or if not, provide 0 value" />
</div>
<br/>
<div class="nextitem">New Item
</div>
</td>
</tr>
</table>
You may also want to clear the inputs of the original object so that it is empty after the clone is created. (or clear the inputs of the cloned object, up to you).

Try below code
Use obj.parents('table').find("tr:eq(0)").after(clonedObj); instead of obj.parents('table').append(clonedObj);
$('.createNewItemTag').click(function() {
var obj = $(this).parents('tr').first(),
clonedObj = $(obj[0].outerHTML);
clonedObj.find(".select2-container").remove();
clonedObj.find('.createNewItemTag').remove();
clonedObj.find('td').last().append("<a class='removeItem' href='javascript:void(0)';>Remove</a>");
clonedObj.find(".removeItem").click(function() {
$(this).parents('tr').first().remove();
});
//console.log(obj);
obj.parents('table').find("tr:eq(0)").after(clonedObj);
//initSelect2ForNextItem(clonedObj.find(".selectItemsList").first());
});

Js Fiddle Demo : JSFiddle

Something like this?
$(document).on('click', '.createNewItemTag', function() {
var rw = $(this).parents('tr');
var ix = rw.index() +1; //remove +1 to insert above curr row
var obj= rw.clone();
obj.addClass('newcol').find('td:first-child').text('New Item');
$('table tr:nth-child('+ix+')').after(obj);
});
table{border-collapse:collapse;}
th,td{border:1px solid #ccc;}
.newcol td{background-color:palegreen;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table>
<tr>
<td colspan="2"><input type="text" value="customerid"></td>
</tr>
<tr>
<td>
<div id="stlineitems"><label for="stlineitems">Item(s)</label></div>
</td>
<td>
<div class="onlyleft">
<select>
<option>Options go here</option>
</select>
</div>
<div class="moveboxleft">
<input type="text" value="Provide Rate" />
</div>
<br/>
<div class="nextitem">New Item
</div>

Notes:
(1) Switched to using .on() to allow newly added rows to be cloned

I do have a form wherein if a user enters input it should check for negative or empty input box and throw an alert message

Here is my code below. I do have a form wherein consists of three dropdowns and input boxes.So I do want to check whether a field is blank or for negative numbers being entered?
//Dependant dropdown code
$("#item").change(function() {

if(parseInt(txt) < 0 || txt == -1){
alert("Enter positive values ..!!!!");
}else{
$('#sess').text($('#sesion').val());
$('#ite').text($('#item').val());
$('#new').text($('#new_select').val());

I am trying to take input from user where validation is needed and once it is validated goes to modal popup to confirm then submit process..

If HTML5 validation is supported, you do not need jQuery for validation.
<input type=number min=0 required placeholder='Enter a positive number'>
If you want a custom validation message, the following should do:
<input type=number min=0 required placeholder="Enter a positive number"
oninvalid="this.setCustomValidity('Enter User Name Here')"
oninput="setCustomValidity('')">
The :invalid psuedo class can be used to apply custom CSS to it.
This link contains some examples. For browser support see caniuse.
EDIT:
For dropdowns, you may use the required attribute.
<select required>
<option value="">None</option>
<option value="Option1">Option1</option>
<option value="Option2">Option2</option>
<option value="Option3">Option3</option>
</select>
Note that the first option has to be blank. For details on applying required to <select> see this question.

Cloning table with hidden row

I have a repeating table with a hidden row and when clicking the a checkbox I have the row appearing, however when adding more than one table the same row always appears instead of the row that has just been cloned. I would appreciate any help with this.
My code looks like the following:
HTML:
<table class="repeatingTable">
<tr>
<td>
<label for="name">Name</label>
</td>
<td>
<input type="text" name="name" id="InputName" class="InputID_1" />
</td>
<td>
<label for="req">Required</label>
</td>
<td>
<input type="checkbox" name="req" id="CheckBox" class="ChexkBox_1" readonly="readonly" />
</td>
</tr>
<tr id="HiddenFields" class="HiddenFields_1">
<td>
<label for="Box">Box Number</label>
</td>
<td>
<input type="number" name="Box" id="InputBoxNo" class="InputBoxNo_1" readonly="readonly" />
</td>
<td>
<label for="id">ID Number</label>
</td>
<td>
<input type="number" name="id" id="inputNo" class="InputNo_1" />
</td>
</tr>
</table>
<div class="expensesBtns">
<input id="repeatingBtn" type="button" value="Add Another" />
</div>
Javascript:
document.getElementById("HiddenFields").style.visibility = "hidden";
$('.ChexkBox_1').click(function () {
if (!$(this).is(':checked')) {
document.getElementById("HiddenFields").style.visibility = "hidden";
}
else {
document.getElementById("HiddenFields").style.visibility = "visible";
}
})
$('#repeatingBtn').click(function (e) {
//$('.expensesSection').clone(false).find("*[id]").andSelf().each(function () {
// $(this).attr("id", $(this).attr("id") + "_cloned");
//})
e.preventDefault();
var lastRepeatingGroup = $('.repeatingTable').last();
var cloned = lastRepeatingGroup.clone(true);
cloned.insertAfter(lastRepeatingGroup);
cloned.find("input").val("");
//resetAttributeNames(cloned);
});
I have a js fiddle here: jsfiddle
Any help is greatly appreciated.

Check your UPDATED FIDDLE.
Worked after some changes in ChexkBox_1 click event, you have to use $(this) instead of document.getElementById("HiddenFields") to deal with current checkbox clicked :
$('.ChexkBox_1').click(function () {
if (!$(this).is(':checked')) {
$(this).parents('table').find(".HiddenFields_1").css('visibility',"hidden");
}
else {
$(this).parents('table').find(".HiddenFields_1").css('visibility',"visible");
}
});
NOTE : when you clone the row you have to change id because element IDs should be unique within the entire document.
