How to merge rows based on <td> class? (Javascript)

I'm currently trying to make it so that when the JS code does its thing, the rows with common values and common classes will be merged. The code worked, but all of the common rows were merged without taking into account their classes.
Table code:
<tbody id="property_dtl_table_body">
<% dtls.each do |f| %>
<tr class="<%= payment_paid(f.paid)%>" id="paidrow">
<td>
<% if !f.paid %>
<%= check_box_tag "pin_number[]", f.id, checked= !f.paid? %>
<%end%>
</td>
<td id="pin"><%= f.year %></td>
<td><%= f.quarter %></td>
<td align="right" id="price"><%= number_to_currency(f.amount, unit: "",
precision: 2)%></td>
</tr>
<%end%>
</tbody>
JS Code:
if(!$(this).hasClass('paid')){
var table = $("#property_dtl_table_body");
var rows = table.find($("tr"));
var colsLength = 2;
var removeLater = new Array();
for(var i=1; i<colsLength; i++){
var startIndex = 0;
var lastIndex = 0;
var startText = $($(rows[0]).find("td")[i]).text();
for(var j=1; j<rows.length; j++){
var cRow =$(rows[j]);
if(!$(this).hasClass('paid')){
var cCol = $(cRow.find("td")[i]);
}
var currentText = cCol.text();
if(currentText==startText){
cCol.css("background","gray");
console.log(cCol);
removeLater.push(cCol);
lastIndex=j;
}else{
var spanLength = lastIndex-startIndex;
if(spanLength>=1){
console.log(lastIndex+" - "+startIndex)
//console.log($($(rows[startIndex]).find("td")[i]))
$($(rows[startIndex]).find("td")
[i]).attr("rowspan",spanLength+1);
}
lastIndex = j;
startIndex = j;
startText = currentText;
}
}
var spanLength = lastIndex-startIndex;
if(spanLength>=1){
console.log(lastIndex+" - "+startIndex)
//console.log($($(rows[startIndex]).find("td")[i]))
$($(rows[startIndex]).find("td")
[i]).attr("rowspan",spanLength+1);
}
console.log("---");
}
for(var i in removeLater){
$(removeLater[i]).remove();
}
}
The class in question(#paid) is represented by the green background color as seen here:

Expected result:

You can go for the following logic:
Start on the first year td
Loop through the next year td's until you find a different one and count them
When you find one, set the first td's rowspan to the number of elements in between
Remove all those td's that you looped through
Repeat the process until the end
The same classe restriction only applies to the selector that you use to fetch all the tds.
Example:
function mergeByClass(className){
let currTd, count = 0;
$(`tr > .${className}`).each(function(){
if (!currTd) //if its the first one set it as current
currTd = $(this);
else { //if its not
if ($(this).text() == currTd.text()){ //check if its a repeating one
count++; //count if it is
$(this).remove(); //and remove it to properly merge
}
else { //if its a different one
if(count >= 1) //merge if it has 1 or more in between
currTd.attr("rowspan", count + 1);
currTd = $(this); //reset the current one
count = 0;
}
}
});
if (count >= 1) //last element case
currTd.attr("rowspan", count + 1);
}
$("#merge").on("click", () => mergeByClass("paid"));
td {
border: 1px solid black;
padding : 15px;
}

jQuery/Javascript compare two tables against each other

I need to compare two HTML tables' rows assuming that data in first cell can be duplicated but data in second cell is always unique. I need to find whether first cell AND second cell in table1 is the same as data in first cell AND second cell in table2 for instance:
Table1:
<Table>
<tr>
<td>123</td>
<td>321</td>
</tr>
<tr>
<td>545</td>
<td>345</td>
</tr>
<tr>
<td>0</td>
<td>312</td>
</tr>
<tr>
<td>123</td>
<td>323331</td>
</tr>
</Table>
Second table:
<table>
<tr>
<td>545</td>
<td>345</td>
</tr>
<tr>
<td>545</td>
<td>3122</td>
</tr>
<tr>
<td>123</td>
<td>321</td>
</tr>
</table>
The result of this should be:
123 321 - good, do nothing
545 345 - good, do nothing
545 3122 - wrong its not in table1 <-
Here's what I've got so far...
$('#runCheck').click(function(){
var firstTable = $('#firstDiv table tr');
var secondTable = $('#secDiv table tr');
$(secondTable).each(function(index){
var $row = $(this);
var secTableCellZero = $row.find('td')[0].innerHTML;
var secTableCellOne = $row.find('td')[1].innerHTML;
$(firstTable).each(function(indexT){
if ($(this).find('td')[0].innerHTML === secTableCellZero){
if ($(this).find('td')[1].innerHTML !== secTableCellOne){
$('#thirdDiv').append("first: " + secTableCellZero + " second: " + secTableCellOne+"<br>");
}
}
});
});
});
Where am I going it wrong?
Just to clarify once again:
2nd table says :
row1 - john|likesCookies
row2 - peter|likesOranges
1st table says :
row1 - john|likesNothing
row2 - john|likesCookies
row3 - steward|likesToTalk
row4 - peter|likesApples
now it should say :
john - value okay
peter - value fail.
a lot alike =VLOOKUP in excel

Check this working fiddle : here
I've created two arrays which store values in each row of tables 1 and 2 as strings. Then I just compare these two arrays and see if each value in array1 has a match in array 2 using a flag variable.
Snippet :
$(document).ready(function() {
var table_one = [];
var table_two = [];
$("#one tr").each(function() {
var temp_string = "";
count = 1;
$(this).find("td").each(function() {
if (count == 2) {
temp_string += "/";
}
temp_string = temp_string + $(this).text();
count++;
});
table_one.push(temp_string);
});
$("#two tr").each(function() {
var temp_string = "";
count = 1;
$(this).find("td").each(function() {
if (count == 2) {
temp_string += "/";
temp_string = temp_string + $(this).text();
} else {
temp_string = temp_string + $(this).text();
}
count++;
});
table_two.push(temp_string);
});
var message = "";
for (i = 0; i < table_two.length; i++) {
var flag = 0;
var temp = 0;
table_two_entry = table_two[i].split("/");
table_two_cell_one = table_two_entry[0];
table_two_cell_two = table_two_entry[1];
for (j = 0; j < table_one.length; j++) {
table_one_entry = table_one[j].split("/");
table_one_cell_one = table_one_entry[0];
table_one_cell_two = table_one_entry[1];
console.log("1)" + table_one_cell_one + ":" + table_one_cell_two);
if (table_two_cell_one == table_one_cell_one) {
flag++;
if (table_one_cell_two == table_two_cell_two) {
flag++;
break;
} else {
temp = table_one_cell_two;
}
} else {}
}
if (flag == 2) {
message += table_two_cell_one + " " + table_two_cell_two + " found in first table<br>";
} else if (flag == 1) {
message += table_two_cell_one + " bad - first table has " + temp + "<br>";
} else if (flag == 0) {
message += table_two_cell_one + " not found in first table<br>";
}
}
$('#message').html(message);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

If I understand your requirements, it would be easier to read the first table and store the couples as strings: 123/321, 545/345, etc...
Than you can read the second table and remove from the first list all the rows found in both.
What remains in the list are couples that do not match.

From purely an efficiency standpoint if you loop through the first table just once and create an object using the first cell value as keys and an array of values for second cells, you won't have to loop through that table numerous times
this then makes the lookup simpler also
var firstTable = $('#firstDiv table tr');
var secondTable = $('#secDiv table tr');
var firstTableData = {}
firstTable.each(function() {
var $tds = $(this).find('td'),
firstCellData = $tds.eq(0).html().trim(),
secondCellData == $tds.eq(1).html().trim();
if (!firstTableData[firstCellData]) {
firstTableData[firstCellData] = []
}
firstTableData[firstCellData].push(secondCellData)
})
$(secondTable).each(function(index) {
var $tds = $(this).find('td');
var secTableCellZero = $tds.eq(0).html().trim();
var secTableCellOne = $tds.eq(1).html().trim();
if (!firstTableData.hasOwnProperty(secTableCellZero)) {
console.log('No match for first cell')
} else if (!firstTableData[secTableCellZero].indexOf(secTableCellOne) == -1) {
console.log('No match for second cell')
}
});
I'm not sure what objective is when matches aren't found

Getting coordinates of table cells and comparing with different tables via Javascript

It's really easy to access to coordinates of table cells with this and this example ways. But when I'm trying to get cells and compare with another table's cell which is avaible on page, a problem occurs. Because I don't know how to compare them in same time. After many hours I tried to do this, unfortunately, still there is no luck.
In following classic tables list below, shows 2 different tables with different id numbers:
<table id="a1">
<tbody>
<tr>
<td>RED</td>
<td>GREEN</td>
<td>BLUE</td>
</tr>
<tr>
<td>YELLOW</td>
<td>PINK</td>
<td>samespothere</td>
</tr>
</tbody>
</table>
<hr>
<table id="a2">
<tbody>
<tr>
<td>BLACK</td>
<td>BROWN</td>
<td>WHITE</td>
</tr>
<tr>
<td>CYAN</td>
<td>GRAY</td>
<td>samespothereANDsomeextra</td>
</tr>
</tbody>
</table>
And also, I'm using modified version of this JS example to get location of cells. This modified version I did is not able to make compare operation. I've just edited for make it easier.
var cells = document.getElementsByTagName("td"); //For all table cells on page.
var i;
for(i = 0; i < cells.length; i++)
{
cells[i].onclick = vera;
}
function vera()
{
var cellIndex = this.cellIndex + 1;
var rowIndex = this.parentNode.rowIndex + 1;
var centra = cellIndex +","+ rowIndex; //This gives the coordinate of cell which you clicked on.
alert(centra);
}
Here is my question: I need to make a compare operation when I click on samespothere(Example text I wrote) table cell. Compare operation should be able with the same location of other table. Lets think like this: If second table cell(same location, different table) includes some of clicked cell's text(from first table), alert must show up and say "This clicked text in table id=1 cell:2row:2, matched in table id=2 cell:2row:2".
And here is the online code: http://jsfiddle.net/LujydnaL/

I think this is what you want:
function vera()
{
var cellIndex = this.cellIndex + 1;
var rowIndex = this.parentNode.rowIndex + 1;
var centra = cellIndex +","+ rowIndex; //This gives the coordinate of cell which you clicked on.
alert(centra);
// new code here
table2 = document.getElementById('a2');
rowInTable2 = table2.getElementsByTagName('tr')[rowIndex-1];
cellInTable2 = rowInTable2.getElementsByTagName('td')[cellIndex-1];
console.log(cellInTable2);
// do something with cellInTable2 now
}

window.onload = function () {
document.getElementsByTagName('table')[0].addEventListener('click', function(element) {
var rowIndex = element.target.parentElement.rowIndex;
var cellIndex = element.target.cellIndex;
var compare = document.getElementsByTagName('table')[1].rows[rowIndex].cells[cellIndex];
var myNodelist = document.querySelectorAll("td");
var i;
for (i = 0; i < myNodelist.length; i++) {
myNodelist[i].style.backgroundColor = "white";
}
compare.style.backgroundColor = "grey";
document.getElementById('alert1').innerHTML = ('CLICK => Row index = ' + rowIndex + ', Column index = ' + cellIndex);
document.getElementById('alert2').innerHTML = ('COMPARE = ' + compare.innerHTML)
}, false);
}
tr, th, td {
padding: 0.2rem;
border: 1px solid black
}
table:hover {
cursor: pointer;
}
<table>

<tr>
<td>a11</td>
<td>a12</td>
<td>a13</td>

How do I select rows that correspond to a rowspan?

I have a dynamically generated table that I am trying to change the background color of certain rows in. Sometimes there are rows with rowspans and I cant figure out how to get all of the rows that correspond to the one "row." I've googled my brains out and found this jsfiddle which is pretty close to what i need (in a logic sense)
http://jsfiddle.net/DamianS1987/G2trb/
basically i have something like this:
and I want to be able to highlight full rows at a time like this:
but the only highlighting i can achieve on rowspan rows is this:
Here is my code (different from jsfiddle but essentially same logic)
CSS:
.highlightedClass{
background-color: #AEAF93;
}
HTML:
<table border="1" class="altTable">
<th>ID</th>
<th>NAME</th>
<th>Miles</th>
<th>WORK</th>
<tbody>
<tr>
<td class="td_id">999B</td>
<td class="td_name ">John</td>
<td class="td_cumMiles">702.4</td>
<td class="td_workEvent">Y</td>
</tr><tr>
<td class="td_id" rowspan="2">111A</td>
<td class="td_name">Tom</td>
<td class="td_cumMiles">446.5</td>
<td class="td_workEvent">Y</td>
</tr><tr>
<td class="td_name">Becky</td>
<td class="td_cumMiles">446.5</td>
<td class="td_workEvent">A</td>
</tr>
</tbody>
JAVASCRIPT:
for(var j=0; j < inspection.length; j++){
var $tr = $('<tr></tr>');
var $td_id = $('<td></td>').addClass('td_id').html(inspection.id);
$tr.append($td_id);
$table.append($tr);
$.each(inspection[i], function(index, value){
var $td_name, $td_miles,$td_workEvent;
if(index > 0){
var $2nd_tr = $('<tr></tr>');
$td_name = $('<td></td>').addClass('td_name').html(value.stationSt);
$td_miles = $('<td></td>').addClass('td_miles').html(value.miles);
$td_workEvent = $('<td></td>').addClass('td_workEvent').html(value.code);
$2nd_tr.append($td_name);
$2nd_tr.append($td_miles);
$2nd_tr.append($td_workEvent);
$table.append($2nd_tr);
$td_id.attr('rowSpan',index+1);
if($td_id.text() === content().id){
$2nd_tr.addClass("highlightedClass");
}else{
if($2nd_tr.hasClass("highlightedClass")){
$2nd_tr.removeClass('highlightedClass');
}
}
$('#workevent').on('click', function(){
$tr.removeClass('highlightedClass');
});
}else{
$td_name = $('<td></td>').addClass('td_name').html(value.stationSt);
$td_miles = $('<td></td>').addClass('td_miles').html(value.miles);
$td_workEvent = $('<td></td>').addClass('td_workEvent').html(value.code);
$tr.append($td_name);
$tr.append($td_miles);
$tr.append($td_workEvent);
$table.append($tr);
if($td_id.text() === content().id){
$tr.addClass("highlightedClass");
}else{
if($tr.hasClass("highlightedClass")){
$tr.removeClass('highlightedClass');
}
}
$('#workevent').on('click', function(){
$tr.removeClass('highlightedClass');
});
}
});

You need to look for any rowspan= attribute in the selected tds and if present, select the subsequent row(s) as well. This example should support any rowspan value (it appends subsequent rows based on the rowspan count):
Final version: JSFiddle: http://jsfiddle.net/TrueBlueAussie/G2trb/22/
$('td').bind('click', function () {
var $row = $(this).closest('tr');
// What row index is the clicked row?
var row = $row.index(); // Subtract heading row
// Does the clicked row overlap anything following?
var rowspan = ~~$row.find('td[rowspan]').attr('rowspan') || 0;
// Get all rows except the heading, up to the last overlapped row
var $rows = $row.parent().children().slice(1, row + rowspan);
row--; // Subtract the heading row we excluded
// Now see if any preceding rows overlap the clicked row
$rows.each(function (i) {
var $tr = $(this);
// Only check first rowspan of a row
var rowspan = ~~$tr.find('td[rowspan]').attr('rowspan') || 0;
// If the rowspan is before the clicked row but overlaps it
// Or it is a row we included after the selection
if ((i < row && ((rowspan + i) > row)) || i > row) {
$row = $row.add($tr);
}
});
$row.toggleClass('green');
});
First attempt JSFiddle: http://jsfiddle.net/TrueBlueAussie/G2trb/18/
$('td').bind('click', function () {
var $td = $(this);
var $row = $td.closest('tr');
var $tds = $row.find('td');
$tds.each(function(){
var rowspan = ~~$(this).attr('rowspan');
while (--rowspan > 0){
$row = $row.add($row.next());
}
});
$row.toggleClass('green');
});
It needs to be tweaked for the child row that sits under a previous rowspan, but am working on that too.
Notes:
~~ is a shortcut to convert a string to an integer.
the || 0 converts undefined values to 0.
$row = $row.add($tr) is appending row elements to a jQuery collection/object.

In fixing my issue (going off what TrueBlueAussie gave me) I came up with the following solution.
CSS:
.highlightedClass{
background-color: #AEAF93;
}
HTML:
<table border="1" class="altTable">
<th>ID</th>
<th>NAME</th>
<th>Miles</th>
<th>WORK</th>
<tbody>
<tr>
<td class="td_id">999B</td>
<td class="td_name ">John</td>
<td class="td_cumMiles">702.4</td>
<td class="td_workEvent">Y</td>
</tr><tr>
<td class="td_id" rowspan="2">111A</td>
<td class="td_name">Tom</td>
<td class="td_cumMiles">446.5</td>
<td class="td_workEvent">Y</td>
</tr><tr>
<td class="td_name">Becky</td>
<td class="td_cumMiles">446.5</td>
<td class="td_workEvent">A</td>
</tr>
</tbody>
JAVASCRIPT:
for(var j=0; j < inspection.length; j++){
var $tr = $('<tr></tr>');
var $td_id = $('<td></td>').addClass('td_id').html(inspection.id);
$tr.append($td_id);
$table.append($tr);
$.each(inspection[i], function(index, value){
var $td_name, $td_miles,$td_workEvent;
if(index > 0){
var $2nd_tr = $('<tr></tr>');
$td_name = $('<td></td>').addClass('td_name').html(value.stationSt);
$td_miles = $('<td></td>').addClass('td_miles').html(value.miles);
$td_workEvent = $('<td></td>').addClass('td_workEvent').html(value.code);
$2nd_tr.append($td_name);
$2nd_tr.append($td_miles);
$2nd_tr.append($td_workEvent);
$table.append($2nd_tr);
$td_id.attr('rowSpan',index+1);
if($td_id.text() === content().td_id){
$2nd_tr.addClass("highlightedClass");
}else{
if($2nd_tr.hasClass("highlightedClass")){
$2nd_tr.removeClass('highlightedClass');
}
}
$('#workevent').on('click', function(){
if($td_id.text() === content().td_id){
$2nd_tr.addClass("highlightedClass");
}else{
if($2nd_tr.hasClass("highlightedClass")){
$2nd_tr.removeClass("highlightedClass");
}
}
});
}else{
$td_name = $('<td></td>').addClass('td_name').html(value.stationSt);
$td_miles = $('<td></td>').addClass('td_miles').html(value.miles);
$td_workEvent = $('<td></td>').addClass('td_workEvent').html(value.code);
$tr.append($td_name);
$tr.append($td_miles);
$tr.append($td_workEvent);
$table.append($tr);
if($td_id.text() === content().id){
$tr.addClass("highlightedClass");
}else{
if($tr.hasClass("highlightedClass")){
$tr.removeClass('highlightedClass');
}
}
}
});
This was in a nested if statement. below like three if statements, i put this:
$('#workevent').on('click', function(){
var flag= false;
$('#altTable > tbody > tr').each(function() {
$td_id= $(this).find('.td_id');
if($td_id.text() === ''){
if(flag === true){
$(this).addClass("highlightedClass");
flag = true;
}
}else{
if(if($td_id.text() === content().idtd_id{){
if($(this).hasClass("highlightedClass")){
flag = true;
}else{
$(this).addClass("highlightedClass");
flag = true;
}
}else{
flag = false;
if($(this).hasClass("highlightedClass")){
$(this).removeClass("highlightedClass");
}
}
}
});
});
This is what worked for me. I selected TrueBlueAussie's answer because it helped get me my specific answer. Hopefully both answers can help someone else in the future.

Javascript: fetch values from textbox of a dynamic datagrid. (skipping some textboxes)

i have seen similar questions to this but none can assist me.as my code is missing some results and i don't now why.
as seen on the image above the output is 6 results instead of 12
This is the code am using to get the values
//Fetch Sales**********************************************
function fetchsales(){
var Dt = document.getElementById("sDate").value;
var Usr = document.getElementById("UserID").value;
var Stp = document.getElementById("tstamp").value;
var e = document.getElementById("sdepot");
var Dpt = e.options[e.selectedIndex].value;
var sale = new Array();
var Tbl = document.getElementById('tbl_sales'); //html table
var tbody = Tbl.tBodies[0]; // Optional, based on what is rendered
for (var i = 2; i < tbody.rows.length; i++) {
var row = tbody.rows[i];
for (var j = 2; j < row.cells.length; j++) {
var cell = row.cells[j];
// For Every Cell get the textbox value
var unitsold = cell.childNodes[0].value ;
//Get selectbox distributor
var Sdist = row.cells[1].childNodes[0]; //Select box always on second coloumn
var Distributor = Sdist.options[Sdist.selectedIndex].value;
//Get selectbox Product
var Sprod = tbody.rows[1].cells[j].childNodes[0];
var Product = Sprod.options[Sprod.selectedIndex].value;
sale[(j*i)] = new Array ('('+Dt,Dpt,Product,unitsold,Distributor,Usr,Stp+')<br/>');
}
}
//Debug
var fsale = new Array();
fsale = sale.filter(function(n){return n});
document.getElementById("output").innerHTML = fsale;
}

NB: am hoping to concatenate the result to a mysql insert statement
Any assistance will be greatly appreciated.

The problem comes from this line:
sale[(j*i)] = new Array ('('+Dt,Dpt,Product,unitsold,Distributor,Usr,Stp+')<br/>');
using the for loops indexes multiplied by themselves doesnt ensure unique array indexes, in some cases they are repeated (like for example 2*3 and 3*2) and the previous value in the array gets overwritten.
