Insert HTML table row clone at index without jquery - javascript

I am attempting to insert a row at the index of the addmorebutton td row.
First attempt indeed adds a row at the desired index however not as I would have expected, simply as space vs actually adding a bounded row column box.
How do I insert a new row at the clicked index of td that is empty and is indeed apart of the table?
function deleteRow(row) {
var i = row.parentNode.parentNode.rowIndex;
document.getElementById('Table').deleteRow(i);
}
function addRow() {
var i = row.parentNode.parentNode.rowIndex;
document.getElementByID('Table').insertRow(i);
}
turkSetAssignmentID();
<script type='text/javascript' src='https://s3.amazonaws.com/mturk-public/externalHIT_v1.js'></script>
<form name='mturk_form' method='post' id='mturk_form' action='https://www.mturk.com/mturk/externalSubmit'>
<input type='hidden' value='' name='assignmentId' id='assignmentId' />
<h1>This is a test</h1>
<div id="tablediv">
<input type="button" id="addbutton" value="Add Index" /><br/><br/>
<table id="Table" border="1">
<tr>
<td>Index</td>
<td>Measured Depth</td>
<td>Inclination</td>
<td>Azimuth</td>
<td>Delete?</td>
<td>Add Row?</td>
</tr>
<tr>
<td>1</td>
<td><input size=25 type="text" id="Measured Depth" contenteditable='true'></td>
<td><input size=25 type="text" id="Inclination" contenteditable='true'></td>
<td><input size=25 type="text" id="Azimuth" contenteditable='true'></td>
<td><input type="button" id="delbutton" value="Delete" onclick="deleteRow(this)" /></td>
<td><input type="button" id="addmorebutton" value="Add More Indexs" onclick="addRow.apply(this)" /></td>
</tr>
</table>
</div>
<p><input type='submit' id='submitButton' value='Submit' /></p>
</form>

You could try to add the respective cells to new row, saving the row on a var and the with the appendChild() function. Something like this:
function addRow(row) {
var i = row.parentNode.parentNode.rowIndex + 1;
var nextRow = document.getElementById('Table').insertRow(i);
// Start iterating over all the cells on the row
var cell = nextRow.insertCell(0);
cell.appendChild(document.createTextNode(i));
cell = nextRow.insertCell();
cell = nextRow.insertCell();
cell = nextRow.insertCell();
cell = nextRow.insertCell();
cell = nextRow.insertCell();
input = document.createElement("Input");
input.type = "button";
input.setAttribute("onclick", "addRow(this)");
input.value = "Add More Indexs"
cell.appendChild(input);
}
And of course append on each cell the respective input.
Then maybe you would like to add a function to increase the index number of the rows under the new one...
Also I changed the onclick value on the original button to addRow(this).

How to get the value of input type text from the last row of a table

I have a table in my page and i have input type text in each row, one of them is for srno
I want to get the value of srno text box from the last row of the table using JavaScript.
Here's a code snippet with my HTML:
<table id="vattable" class="table table-sm table-striped">
<thead class="thead-light">
<tr>
<th style="width:50px">SRNo</th>
</tr>
</thead>
<tbody>
<tr>
<td><input type="text" class="text-control input-sm" readonly name="srno[]" id="srno" value=1 style="text-align:right;max-width:40px;" maxlength="13" /></td>
</tr>
</tbody>
</table>
Actually I am adding rows on button click event in JavaScript, I want to get the last value of srno column and give the next srno with +1 each time the row is created in the table. when the page is loaded I am selecting data from database and fetching in this table so sometime this table may have few rows already and when I click button to create row it should take the last srno and add +1 to the new row srno.
I think that this should work for you if you have a similar HTML structure.
What it basically does is:
Scanning the table structure for all inputs with name=srno.
Getting the last input and logging in the javascript console.
You can get its value with lastInput.value.
function getLastInput() {
//get all inputs with name srno in an array
const allInputs = document.querySelectorAll('table tr input[name="srno[]"]');
//get the last input from the array by referring the highest index of the array
const lastInput = allInputs[allInputs.length - 1];
return lastInput;
}
$(document).ready(function() {
var rowcnt = $('#vattable tr').length;
var count = rowcnt;
$(document).on('click', '#addrow', function() {
count = count + 1;
var html_code = '';
html_code += '<tr id="row_id_' + count + '">';
html_code += '<td><input type="text" class="text-control input-sm" name="srno[]" id="srno" readonly style="text-align:right;width:40px" value="' + count + '"/></td>';
html_code += '</tr>';
$('#vattable').append(html_code);
console.log(getLastInput());
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="vattable">
<tr>
<td>
<input type="text" name="srno[]" value="1" />
</td>
</tr>
<tr>
<td>
<input type="text" name="srno[]" value="2" />
</td>
</tr>
<tr>
<td>
<input type="text" name="srno[]" value="3" />
</td>
</tr>
<tr>
<td>
<input type="text" name="srno[]" value="4" />
</td>
</tr>
</table>
<button id="addrow">Add row</button>
EDIT:
Use this if your input name is srno[].
//get all inputs with name srno[] in an array
const allInputs = document.querySelectorAll('table tr input[name="srno[]"]');
//get the last input from the array by referring the highest index of the array
const lastInput = allInputs[allInputs.length - 1];
console.log(lastInput);

Trying to Add Row dynamically but getting error

I'm trying to add row consist of three textbox dynamically on click of button with id=btnASize and on click of button with id=btnASizeR want to add a row consist of four textboxes. and on click of button with id=btnWdDelete want to delete the last row which is generated with textboxes and so on.
The three buttons which is mentioned above are generated dynamically and rows with textboxes which will be generated below existing rows are also created on click of those dynamic buttons.Any idea would be appreciated Refer image
$("#btnASize").click(function () {
AddRow($("#SizeR").val(), $("#TolMin").val(), $("#TolMax").val());
$("#SizeR").val("");
$("#TolMin").val("");
$("#TolMax").val("");
});
function insertRow(){}
function AddRow(SizeRange, Tolerancemin,Tolerancemax) {
//Get the reference of the Table's thead element.
var tBody = $("#WireDimTbl > thead> tr")[0];
//Add Row.
row = tBody.insertRow(-1);

I prepared this sample to fulfill your requirement, although not a complete solution. You have to write some code by yourself. But this will give you a pretty good idea.
$('#btnAdd').click(function() {
var textboxSize = "<input class='form-control' type='text' class='size range'>";
var textboxTolerance = "<input class='form-control' type='text' class='tolerance'>";
var markup = "<tr><td>" + textboxSize + "</td><td>" + textboxTolerance + "</td></tr>";
$("#myTable tbody").append(markup);
});
$('#btnDelete').click(function() {
$("#myTable tbody>tr:last").remove();
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I think there are a few issues with your code.
You call insertRow on an HTMLTableRowElement. insertRow is a HTMLTableElement method, so we need to make sure we're calling it on a HTMLTableElement, instead of a HTMLTableRowElement. To fix this, we'll select the table. We can then use insertRow() on it.
You call $(row.insertCell(-1)) to insert a cell. This is invalid jQuery code. insertCell is a plain JS method for a HTMLTableRowElements, so we need to make sure we're calling it on the appropriate type of element. Specifically, we'll use row.insertCell(), instead of $(row.insertCell(-1)).
The Delete function contains similar errors, but I'll leave that one as is so you can learn by correcting it yourself.
$("#btnASize").click(function() {
AddRow($("#SizeR").val(), $("#TolMin").val(), $("#TolMax").val());
$("#SizeR").val("");
$("#TolMin").val("");
$("#TolMax").val("");
});
function AddRow(SizeRange, Tolerancemin, Tolerancemax) {
//Get the reference of the Table's thead element.
var tBody = $("#WireDimTbl")[0];
//Add Row.
row = tBody.insertRow(-1);
//Add Size cell.
var cell1 = row.insertCell(-1);
$(cell1).text(SizeRange);
//Add TolMin cell.
var cell2 = row.insertCell(-1);
$(cell2).text(Tolerancemin);
//Add TolMax cell.
var cell3 = row.insertCell(-1);
$(cell3).text(Tolerancemax);
}
$("#btnWdDelete").click(function() {
var row = $("#SizeR").closest("tr");
//Get the reference of the Table.
var table = $("#WireDimTbl")[1];
//Delete the Table row using it's Index.
table.deleteRow(row[1].rowIndex);
});

Add new cell to a table in javascript

I have this code to automatically display a new row every time the students need to add a new subject to the table. After entering all the information needed, the student will have to click on a button that will enable the student to view the grades and gpa of each subject which is supposed to be displayed in a new added cell to the table.
My question is, how can I add a new cell to automatically display the grades and GPA for each subject based on the expected marks entered by the student?
<html>

function addRow(myTable) {
var table = document.getElementById("myTable");

var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
cell1.appendChild(element1);
var cell2 = row.insertCell(1);
var element2 = document.createElement("input");
cell2.appendChild(element2);
var cell3 = row.insertCell(2);
var element2 = document.createElement("input");
cell3.appendChild(element2);
var cell4 = row.insertCell(3);
var element3 = document.createElement("input");
cell4.appendChild(element3);
}

#RobG I think the only way, to my knowledge, would to use a SQL database and have it be updated via a SQL client. This can be done with software like ISS (built-in to Windows Vista+) or other third-party SQL clients.
Edit: #RobG, I understand that, however, the easiest way to accomplish this is to fetch rows out of a database or even a Microsoft Excel file to use as variables for the grades the student(s) have.
The jquery below works when the element's value changed;
$('.myElements').each(function() {
var elem = $(this);
// Save current value of element
elem.data('oldVal', elem.val());
// Look for changes in the value
elem.bind("propertychange change click keyup input paste", function(event){
// If value has changed...
if (elem.data('oldVal') != elem.val()) {
// Updated stored value
elem.data('oldVal', elem.val());
// Do action - You can call javascript function to add cell
....
}
});
});
When the input value changed you can add one more cell like this(Im in grade);
var row = document.getElementById("myRow");
var x = row.insertCell(0);
x.innerHTML = "New cell";
Once you have all grades you can calculate the GPA from grade's values as you wish.
I hope this helps you mate.

Delete button is not working

Html Table:
<table width="100%" border="0" cellspacing="0" cellpadding="0" id="table-data">
<tr>
<td>Name</td>
<td>Location</td>
<td>From</td>
<td>To</td>
<td>Add</td>
</tr>
<tr class="tr_clone">
<td><input type="text" placeholder="who" name="who" /></td>
<td><input type="text" placeholder="location" name="location" /></td>
<td><input type="text" placeholder="Start Date" name="datepicker_start" class="datepicker"/></td>
<td><input type="text" placeholder="End Date" name="datepicker_end" class="datepicker"/></td>
<td><input type="button" name="add" value="Add" class="tr_clone_add"/></td>
<td><input type="button" value="Delete" onclick="deleteRow(this)"/></td>
</tr>
</table><!-- /table#table-data -->
Javascript:
$("input.tr_clone_add").live('click', function() {
var $tr = $(this).closest('.tr_clone');
var $clone = $tr.clone();
$clone.find(':text').val('');
$tr.after($clone);
});
function deleteRow(r)
{
var i = r.parentNode.parentNode.rowIndex;
document.getElementById("table-data").deleteRow(i);
}
Here is my fiddle:
http://jsfiddle.net/tejdeep/b6A9R/
This code is cloning first two cells of a table row. I have add and delete button for every row.
I want this as like this:
http://jsfiddle.net/nKkhW/5/
Add button wants to be there for the cloning row and delete button should be there for the cloned row.
I want to include the functionality while cloning first two cell values has to come to the cloned row?
Let me know if you have doubts in this question.
What I have understood by your question, on that basis I have created Fiddle. Hope it will help you,except the default value case.
Updated fiddle
To delete row, you can try:
var $actualrow = $(this).closest('.tr_clone');
$actualrow.remove();
<input type="button" value="Delete" onclick="deleteRow(this)"/>
The problem is, where is your deleteRow() ? it's not in your fiddle..
fixed : http://jsfiddle.net/b6A9R/5/
and you have to change onLoad to No wrap, otherwise your function will not work.
Here is the updated code for onLoad.
JS
$(document).on('click','input[value="Delete"]',function(){
deleteRow(this);
});

Dynamically changing the Tab Index for the textbox

I have a requirement to accomplish to change the tab index of the cursor based on how the user wishes to perform. I am not sure what is the best way to achieve this. I have created a fiddle to ensure what is explained here is understood by all.
The requirement is the following:
There is a table with a series of text box on all the rows and columns.
A radio button is provided below the table for the user to be able to move through the text boxes on the table.
Selecting "Move Horizontally" will make the cursor move from each textbox horizontally when a tab is pressed or the max length is reached.
Selection "Move Vertically" will make the cursor move from each textbox vertically when a tab is pressed or the max length is reached.
By default the tab indexes move vertically.
When reaching the last textbox on either the row on the column, the cursor should automatically move to the next row or columns first textbox.
How can I achieve this dynamically when selecting the radio buttons.

jQuery
$(function() {
var inputBox = $('#mytable input[type="text"]').length;
var row = $('#mytable tbody tr').length;
var column = $('#mytable tbody tr:first td').length;
// Vertical
$('input:radio').change(function() {
var self = $(this);
if(self.val() == "V") {
var counter = 1;
for(i=1; i<column; i++) {
for(j=2; j<=row+1; j++) {
$('#mytable tbody tr td:nth-child('+j+')').find('input[type="text"]').attr('tabindex', counter);
counter++;
}
}
}
else {
$('#mytable input[type="text"]').removeAttr('tabindex');
}
});
});
A rough idea is below by jQuery:
// For columns
var textBoxes = $('#tableid input[type="textbox"]').length;
var rowNums = 4;
for(i=0; i<=textBoxes; i++) {
for(j=0; j<=rowNums; j++) {
$('#tableid').find('tr:eq('+j+') input[type="textbox"]').attr('tabindex', i);
}
}
Row indexing can be done also same as above
