JQuery TableSorter not Recognizing Table on JSP Page - javascript

I'm playing around with trying to make tablesorter work for a simple table created using JSP and a Java Bean that reads information from the file.
Here is my jsp that creates the table:
<%
out.println("<table id=\"infoTable\" class=\"tablesorter\" border=\"1\" bgcolor=\"#57976b\" " +
"style=\"border-collapse:collapse;\">");
//Print Table Headings
out.println("<thead><tr>");
for(int i = 0; i < 19; i++) {
String par = parameters.get(i);
out.println("<td>" + par + "</td>");
}
out.println("</tr></thead>");
out.println("<tbody>");
ArrayList<String> values = fileBean.getAllValues();
for(int i = 0; i < values.size(); i++) {
if(i%19 == 0) {
out.println("<tr>");
}
out.println("<td>" + values.get(i) + "</td>");
if(values.get(i).contains("grading") && i%19 != 0) {
out.println("</tr>");
}
}
out.println("</tbody>");
out.println("</table>");
%>
With this script in my <head> tag:
<script>
$(document).ready(function() {
$("#infoTable").tablesorter();
})
</script>
And here is the HTML created using inspect element on the said page:
<table id="infoTable" class="tablesorter" border="1" bgcolor="#57976b" style="border-collapse:collapse;">
<thead><tr>
<td>Grading</td>
<td>Teaching</td>
<td>Name</td>
<td>Title</td>
<td>Home Address</td>
<td>Additional Details</td>
<td>Course Name</td>
<td>Course Credits</td>
<td>Student ID</td>
<td>Additional Duties</td>
<td>Details</td>
<td>Course Grade</td>
<td>Phone Number</td>
</tr></thead>
<tbody>
<tr>
<td>1 </td>
<td>1 </td>
<td>John Doe</td>
<td>Student </td>
<td>Home Address </td>
<td>Web Development! </td>
<td>SWE 432 </td>
<td>4 </td>
</tr>
</tbody>
</table>
The values don't match the headers as this is just an example. I have included <thead> and <tbody> appropriately and the table looks just how I want it. Any idea why tablesorter is not recognizing my table?

Compare Table column with JSON object and update another column in HTML

This is the first time I'm using HTML and Javascript to create a Dashboard. This Dashboard contains a HTML table which contains server name,server desc and time UP,warning critical columns.
From Nagios JSON query generator, I will generate a Availability report URL which returns the JSON value. Now I need to compare the Service Desc in table column and update the the remaining columns by fetching value from the JSON output. How to achieve it.
HTML :
<table id="service_table">
<thead>
<tr>
<th>Service Name</th>
<th>Service Desc</th>
<th>Time OK %</th>
<th>Time Warning %</th>
<th>Time Critical %</th>
</tr
</thead>
<tbody>
<tr>
<td>jenkinsserver</td>
<td>Jenkins PROD GUI</td>
<td>0.00</td>
<td>0.00</td>
<td>0.00</td>
</tr>
<tr>
<td>nexusserver</td>
<td>nexus GUI</td>
<td>0.00</td>
<td>0.00</td>
<td>0.00</td>
</tr>
<tr>
<td>sonarserver</td>
<td>sonrqube GUI</td>
<td>0.00</td>
<td>0.00</td>
<td>0.00</td>
</tr>
<tr>
<td colspan="5" class="bold" style="text-align:center">CLEARCASE</td>
</tr>
<tr>
<td>clearcasewebserver</td>
<td>clearcase web</td>
<td>0.00</td>

</tbody>
</table>
Javascript:
function make_base_auth(user, password) {
var tok = user + ':' + password;
var hash = btoa(tok);
return 'Basic ' + hash;
}
$(document).ready(function(){
var end1 = Math.floor((new Date).getTime()/1000);
var start1 = Math.floor(time.setDate(time.getDate() - 1)/1000);
console.log(end1);
console.log(start1);
servicereport = " http://xx.xx.xx/nagios/cgi-bin/archivejson.cgi?query=availability&availabilityobjecttype=servicegroups&hostgroup=ALM&servicegroup=ALM+Tools&assumedinitialhoststate=up&assumedinitialservicestate=ok&starttime=" + start1 + "&endtime=" + end1;
$.support.cors = true;
$.ajax({
type: "GET",
url: servicereport,
crossDomain: true,
async: false,
beforeSend: function (xhr) {
xhr.setRequestHeader('Authorization',
make_base_auth("nagiosadmin", "nagiosadmin"));
},
dataType: 'json', //data format
success: servicedisplay
});
function servicedisplay(series) {
// 1. remove all existing rows
$('#service_table tbody').empty();
var lent = series.data.servicegroup.services;
var aa = lent.length;
var sm = 0;
var avg = 0;
for (var i=0; i<aa; i++) {
var dataO=series.data.servicegroup.services[i].time_ok;
var dataW=series.data.servicegroup.services[i].time_warning;
var dataC=series.data.servicegroup.services[i].time_critical;
var dataA=(dataO/(dataO + dataW + dataC))*100;
sm +=dataA;
}
avg = sm/aa;
if ( avg < 100 ) {
$('#almserv').css('background-color','red');
} else {
$('#almserv').css('background-color','green');
}
$('#servnum').text(parseFloat(avg).toFixed(2));
$.each(series.data.servicegroup.services, function (index, serv) {
$('<tr>').append(
$('<td>').text(parseFloat((serv.time_ok/(serv.time_ok + serv.time_warning + serv.time_critical)*100)).toFixed(2)),
$('<td>').text(parseFloat((serv.time_warning/(serv.time_ok + serv.time_warning + serv.time_critical)*100)).toFixed(2)),
$('<td>').text(parseFloat((serv.time_critical/(serv.time_ok + serv.time_warning + serv.time_critical)*100)).toFixed(2)),
).appendTo('#service_table');
});
My idea could be something like this:
<table id="service_table">
<thead>
<tr>
<th>Service Name</th>
<th>Service Desc</th>
<th>Time OK %</th>
<th>Time Warning %</th>
<th>Time Critical %</th>
</tr
</thead>
<tbody>
<tr>
<td>jenkinsserver</td>
<td>Jenkins PROD GUI</td>
<td><div id="Col3JPG">0.00</div></td>
<td><div id="Col4JPG">0.00</div></td>
<td><div id="Col5JPG">0.00</div></td>
</tr>
<tr>
<td>nexusserver</td>
<td>nexus GUI</td>
<td><div id="Col3NG">0.00</div></td>
<td><div id="Col4NG">0.00</div></td>
<td><div id="Col5NG">0.00</div></td>
</tr>
<tr>
<td>sonarserver</td>
<td>sonrqube GUI</td>
<td><div id="Col3JPG">0.00</div></td>
<td><div id="Col4SG">0.00</div></td>
<td><div id="Col5SG">0.00</div></td>
</tr>
<tr>
<td colspan="5" class="bold" style="text-align:center">CLEARCASE</td>
</tr>
<tr>
<td>clearcasewebserver</td>
<td>clearcase web</td>
<td><div id="Col3CW">0.00</div></td>
<td><div id="Col4CW">0.00</div></td>

Then in your script, you could create a Switch Statement and do the compare there like:
for (var i=0; i<aa; i++) {
switch(series.data.servicegroup.services[i].VariableWithCol2Content){
case "Jenkins PROD GUI": //code for the changes
$("#col3JPG").text(series.data.servicegroup.services[i].time_ok);
$("#col4JPG").text(series.data.servicegroup.services[i].time_warning);
$("#col5JPG").text(series.data.servicegroup.services[i].time_critical);
//add all require code to update the row
break;
case "nexus GUI": //code for the changes
$("#col3NG").text(series.data.servicegroup.services[i].time_ok);
$("#col4NG").text(series.data.servicegroup.services[i].time_warning);
$("#col5NG").text(series.data.servicegroup.services[i].time_critical);
//add all require code to update the row
break;
//and so on with all of them...

Ok, this example isn't exactly what i'm working on but it's very similar. The only difference is that in mine the rows and buttons are dynamically added by the user and he inserts the details. What I want is that when i press on the button of each row (sell) the details (Item and Sold only) are copied into a row in the second table and checks if the same item exists in this second table if so then it adds the amount of sold of both items in one row. For instance I press on the first row button the Apples it copies the listed above details to the second table in a row and then when i click on the button of the second row (Apples also) it only adds the sold amount up and doesn't add a second apples row because an apples row already exists in the second table but when i click on the oranges button it makes a new row because the oranges row doesn't exist. So how do I do this in JavaScript? i hope i was thorough and made any sense. I have no idea why the code isn't working here but i hope you get the point. This code works perfectly just as i want it to until for some reason i get this error: Cannot read property 'innerText' of undefined when i press the buttons approx. 6-7 times targeting the if statement where i commented error.
This sets a click handler to all buttons. If the row doesn't exist in the second table it's created. It sets a data-type referring to the item. When somebody clicks the sell button again and there is a row containing the data-type the row is updated instead of created. All in plain JavaScript.
var Sell_Button = document.querySelectorAll('.sellbtn'),
secondTable = document.getElementById("secondTableBody");
Array.prototype.slice.call(Sell_Button).forEach(function(element){
element.addEventListener('click', function(e) {
//since the button is an element without children use e.
var clickedElement = e.target;
var parentRow = clickedElement.parentNode.parentNode;
//check if second table has a row with data-type
var rowWithData = secondTable.querySelector("[data-type='"+parentRow.cells[0].childNodes[0].nodeValue+"']");
if (rowWithData)
{
rowWithData.cells[1].innerHTML = parseInt(rowWithData.cells[1].childNodes[0].nodeValue) + parseInt(parentRow.cells[2].childNodes[0].nodeValue);
}
else
{
var Row = secondTable.insertRow();
Row.setAttribute("data-type", parentRow.cells[0].childNodes[0].nodeValue);
for (var c = 0; c < 2; c += 1) {
Row.insertCell(c);
}
Row.cells[0].innerHTML = parentRow.cells[0].childNodes[0].nodeValue;
Row.cells[1].innerHTML = parentRow.cells[2].childNodes[0].nodeValue;
}
});
});

Do you mean something like:
$(document).on("click", "#firstTable tr button", function(b) {
b = $(this).closest("tr");
var d = $.trim(b.find("td:first").text());
b = parseFloat($.trim(b.find("td:nth-child(3)").text()));
var a = $("#secondTable"),
c = a.find("tr").filter(function(a) {
return $.trim($(this).find("td:first").text()) == d
});
c.length ? (a = c.find("td:nth-child(2)"), c = parseFloat($.trim(a.text())), a.text(b + c)) : (a = $("<tr />").appendTo(a), $("<td />", {
text: d
}).appendTo(a), $("<td />", {

merging <td> rows in one column of html table

I have a requirement, if i have same data in column1 of 's with same id then i need to merge those cells and show their respective values in column2.
i.e., in fiddle http://jsfiddle.net/7t9qkLc0/12/ the key column have 3rows with data 1 as row value with same id and has corresponding different values in Value column i.e., AA,BB,CC. I want to merge the 3 rows in key Column and display data 1 only once and show their corresponding values in separate rows in value column.
Similarly for data4 and data5 the values are same i.e.,FF and keys are different, i want to merge last 2 rows in Value column and dispaly FF only one time and show corresponding keys in key column. All data i'm getting would be the dynamic data. Please suggest.
Please find the fiddle http://jsfiddle.net/7t9qkLc0/12/
Sample html code:
<table width="300px" height="150px" border="1">
<tr><th>Key</th><th>Value</th></tr>
<tr>
<td id="1">data 1</td>
<td id="aa">AA</td>
</tr>
<tr>
<td id="1">data 1</td>
<td id="bb">BB</td>
</tr>
<tr>
<td id="1">data 1</td>
<td id="cc">CC</td>
</tr>
<tr>
<td id="2">data 2</td>
<td id="dd">DD</td>
</tr>
<tr>
<td id="2">data 2</td>
<td id="ee">EE</td>
</tr>
<tr>
<td id="3">data 3</td>
<td id="ff">FF</td>
</tr>
<tr>
<td id="4">data 4</td>
<td id="ff">FF</td>
</tr>
<tr>
<td id="5">data 5</td>
<td id="ff">FF</td>
</tr>
</table>
</td>

<tr>
<td colspan="3" style="padding-left: 0px; padding-right: 0px; padding-bottom: 0px">
</td>
</tr>

Building on tkounenis' answer using Rowspan:
One option to implement what you need would be to read all the values in your table after being populated, then use a JS object literal as a data structure to figure out what rows/columns are unique.
A JS object literal requires a unique key which you can map values to. After figuring out what rows/columns should be grouped, you can either edit the original table, or hide the original table and create a new table (I'm creating new tables in this example).
I've created an example for you to create a new table either grouped by key or grouped by value. Try to edit the examples provided to introduce both requirements.
Let me know if you need more help. Best of luck.
JSFiddle: http://jsfiddle.net/biz79/x417905v/
JS (uses jQuery):
sortByCol(0);
sortByCol(1);
function sortByCol(keyCol) {
// keyCol = 0 for first col, 1 for 2nd col
var valCol = (keyCol === 0) ? 1 : 0;
var $rows = $('#presort tr');
var dict = {};
var col1name = $('th').eq(keyCol).html();
var col2name = $('th').eq(valCol).html();
for (var i = 0; i < $rows.length; i++) {
if ($rows.eq(i).children('td').length > 0) {
var key = $rows.eq(i).children('td').eq(keyCol).html();
var val = $rows.eq(i).children('td').eq(valCol).html();
if (key in dict) {
dict[key].push(val);
} else {
dict[key] = [val];
}
}
}
redrawTable(dict,col1name,col2name);
}
function redrawTable(dict,col1name,col2name) {
var $table = $('<table>').attr("border",1);
$table.css( {"width":"300px" } );
$table.append($('<tr><th>' +col1name+ '</th><th>' +col2name+ '</th>'));
for (var prop in dict) {
for (var i = 0, len = dict[prop].length; i< len; i++) {
var $row = $('<tr>');
if ( i == 0) {
$row.append( $("<td>").attr('rowspan',len).html( prop ) );
$row.append( $("<td>").html( dict[prop][i] ) );
}
else {
$row.append( $("<td>").html( dict[prop][i] ) );
}
$table.append($row);
}
}
$('div').after($table);
}
Use the rowspan attribute like so:
<table width="300px" height="150px" border="1">
<tr>
<th>Key</th>
<th>Value</th>
</tr>
<tr>
<td id="1" rowspan="3">data 1</td>
<td id="aa">AA</td>
</tr>
<tr>
<td id="bb">BB</td>
</tr>
<tr>
<td id="cc">CC</td>
</tr>
<tr>
<td id="2" rowspan="2">data 2</td>
<td id="dd">DD</td>
</tr>
<tr>
<td id="ee">EE</td>
</tr>
<tr>
<td id="3">data 3</td>
<td id="ff">FF</td>
</tr>
<tr>
<td id="4">data 4</td>
<td id="ff">FF</td>
</tr>
<tr>
<td id="5">data 5</td>
<td id="ff">FF</td>
</tr>
</table>

Use below snippet of javascript. It should work fine for what you are looking.
<script type="text/javascript">
function mergeCommonCells(table, columnIndexToMerge){
previous = null;
cellToExtend = null;
table.find("td:nth-child("+columnIndexToMerge+")").each(function(){
jthis = $(this);
content = jthis.text();
if(previous == content){
jthis.remove();
if(cellToExtend.attr("rowspan") == undefined){
cellToExtend.attr("rowspan", 2);
}
else{
currentrowspan = parseInt(cellToExtend.attr("rowspan"));
cellToExtend.attr("rowspan", currentrowspan+1);
}
}
else{
previous = content;
cellToExtend = jthis;
}
});
};
mergeCommonCells($("#tableId"), 1);

This sorts just the way I want it if you sort it by the first column, but the other two columns don't maintain the same paired 'tr' sort im looking for.
Any help on this?
Use the expand-child class name on each duplicated row:
<tr>
<td>Test3</td>
<td>3</td>
<td>Hello3</td>
</tr>
<tr class="expand-child">
<td colspan="3">Test3</td>
</tr>
It's defined by the cssChildRow option:
$('table').tablesorter({
cssChildRow: "expand-child"
});​
Here is a demo of it in action.

Javascript
$(document).ready(function(){

});
});
function newSum() {
var $table = $(this).closest('table');
var total = 0;
$(this).attr('class').match(/(\d+)/)[1];
$table.find('tr:not(.totalColumn) .rowDataSd').each(function() {
total += parseInt($(this).html());
});
$table.find('.totalColumn td:nth-child('')').html(total);
}
Here is a jsffile. hope this helps
<table id="sum_table" width="300" border="1">
<tr class="titlerow">
<td>Apple</td>
<td>Orange</td>
<td>Watermelon</td>
</tr>
<tr>
<td class="rowDataSd">1</td>
<td class="rowDataSd">2</td>
<td class="rowDataSd">3</td>
</tr>
<tr>
<td class="rowDataSd">1</td>
<td class="rowDataSd">2</td>
<td class="rowDataSd">3</td>
</tr>
<tr>
<td class="rowDataSd">1</td>
<td class="rowDataSd">5</td>
<td class="rowDataSd">3</td>
</tr>
<tr class="totalColumn">
<td class="totalCol">Total:</td>
<td class="totalCol">Total:</td>
<td class="totalCol">Total:</td>
</tr>
</table>
<script>
var totals=[0,0,0];
$(document).ready(function(){
var $dataRows=$("#sum_table tr:not('.totalColumn, .titlerow')");
$dataRows.each(function() {
$(this).find('.rowDataSd').each(function(i){
totals[i]+=parseInt( $(this).html());
});
});
$("#sum_table td.totalCol").each(function(i){
$(this).html("total:"+totals[i]);
});
});
</script>

To achieve this, we can take full advantage of the thead and tfoot tags within the table element. With minor changes, we have the following:
HTML
<table id="sum_table" width="300" border="1">
<thead>
<tr>
<th>Apple</th>
<th>Orange</th>
<th>Watermelon</th>
</tr>
</thead>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tfoot>
<tr>
<td>Total:</td>
<td>Total:</td>
<td>Total:</td>
</tr>
</tfoot>
</table>​​​​​​​​​​​​​​​
This then allows us to target more specifically the elements we want, i.e. how many columns are there, and what is the "total" cell.
JavaScript
$(document).ready(function()
{
$('table thead th').each(function(i)
{
calculateColumn(i);
});
});
function calculateColumn(index)
{
var total = 0;
$('table tr').each(function()
{
var value = parseInt($('td', this).eq(index).text());
if (!isNaN(value))
{
total += value;
}
});
$('table tfoot td').eq(index).text('Total: ' + total);
}​
$('#sum_table tr:first td').each(function(){
var $td = $(this);
var colTotal = 0;
$('#sum_table tr:not(:first,.totalColumn)').each(function(){
colTotal += parseInt($(this).children().eq($td.index()).html(),10);
});
$('#sum_table tr.totalColumn').children().eq($td.index()).html('Total: ' + colTotal);
});
Live example: http://jsfiddle.net/unKDk/7/
An alternate way:
$(document).ready(function(){
for (i=0;i<$('#sum_table tr:eq(0) td').length;i++) {
var total = 0;
$('td.rowDataSd:eq(' + i + ')', 'tr').each(function(i) {
total = total + parseInt($(this).text());
});
$('#sum_table tr:last td').eq(i).text(total);
}
});
Example: http://jsfiddle.net/lucuma/unKDk/10/
This is easily accomplished with a little tweaking of the classes on your table:
HTML:
<table id="sum_table" width="300" border="1">
<tr>
<td>Apple</td>
<td>Orange</td>
<td>Watermelon</td>
</tr>
<tr>
<td class="col1">1</td>
<td class="col2">2</td>
<td class="col3">3</td>
</tr>
<tr>
<td class="col1">1</td>
<td class="col2">2</td>
<td class="col3">3</td>
</tr>
<tr>
<td class="col1">1</td>
<td class="col2">2</td>
<td class="col3">3</td>
</tr>
<tr>
<td class="total">Total:</td>
<td class="total">Total:</td>
<td class="total">Total:</td>
</tr>
</table>​
JS:
var getSum = function (colNumber) {
var sum = 0;
var selector = '.col' + colNumber;
$('#sum_table').find(selector).each(function (index, element) {
sum += parseInt($(element).text());
});
return sum;
};
$('#sum_table').find('.total').each(function (index, element) {
$(this).text('Total: ' + getSum(index + 1));
});

I know this has been well answered by now, but I started working on this solution earlier before all the answers came through and wanted to go ahead and post it.
This solution works with the HTML as you posted it, and assumes 4 things: 1) the first row is the header row, 2) the last row is the totals row, 3) each row has equal columns, and 4) the columns contain integers. In this case, only the table needs to be identified.
$(document).ready(function(){
totalRows("#sum_table");
});
function totalRows(tableSelector) {
var table = $(tableSelector);
var rows = table.find("tr");
var val, totals = [];
//loop through the rows getting values in the rowDataSd columns
rows
.each(function(rIndex) {
if (rIndex > 0 && rIndex < (rows.length-1)) { //not first or last row
//loop through the columns
$(this).find("td").each(function(cIndex) {
val = parseInt($(this).html());
(totals.length>cIndex) ? totals[cIndex]+=val : totals.push(val);
});
}
})
.last().find("td").each(function(index) {
val = (totals.length>index) ? totals[index] : 0;
$(this).html( "Total: " + val );
});
}
