Copy row from any table

I have an HTML page with 3 tables on it. I want to be able to copy specific cells in a table row to the clipboard. The row could come from any of the 3 tables.
Using the code below, I highlight and copy the row for a table with an ID of "final". How do I make this work for any of the 3 tables? I tried by getElementsByTagName and labeling them the same name but did not work - understandably so. Is there a way to designate the selected table? I am trying to avoid copying the whole row and might eventually add the formatted msg to a new page rather than copy to the clipboard.
function copy_highlight_row() {
var table = document.getElementById('final');
var cells = table.getElementsByTagName('td');
for (var i = 0; i < cells.length; i++) {
// Take each cell
var cell = cells[i];
// do something on onclick event for cell
cell.onclick = function () {
// Get the row id where the cell exists
var rowId = this.parentNode.rowIndex;
var rowsNotSelected = table.getElementsByTagName('tr');
for (var row = 0; row < rowsNotSelected.length; row++) {
rowsNotSelected[row].style.backgroundColor = "";
rowsNotSelected[row].classList.remove('selected');
}
var rowSelected = table.getElementsByTagName('tr')[rowId];
rowSelected.style.backgroundColor = "yellow";
rowSelected.className += " selected";
var cellId = this.cellIndex + 1
msg = 'Title: ' + rowSelected.cells[0].innerHTML;
msg += '\r\nDescription: ' + rowSelected.cells[1].innerHTML;
msg += '\n\nLink: ' + rowSelected.cells[2].innerHTML;
msg += '\nPublication Date: ' + rowSelected.cells[3].innerHTML;
//msg += '\nThe cell value is: ' + this.innerHTML copies cell selected
navigator.clipboard.writeText(msg);
}
}
};

Based on a couple of the suggestions I came up with the following:
function highlight_row() {
var cells = document.querySelectorAll('td')
for (var i = 0; i < cells.length; i++) {
// Take each cell
var cell = cells[i];
// do something on onclick event for cell
cell.onclick = function () {
// Get the row id where the cell exists
var rowId = this.parentNode.rowIndex;
var t_ID = this.closest('table').id
var table=document.getElementById(t_ID);
var rowsNotSelected = table.getElementsByTagName('tr');
for (var row = 0; row < rowsNotSelected.length; row++) {
rowsNotSelected[row].style.backgroundColor = "";
rowsNotSelected[row].classList.remove('selected');
}
var rowSelected = table.getElementsByTagName('tr')[rowId];
rowSelected.style.backgroundColor = "yellow";
rowSelected.className += " selected";
var cellId = this.cellIndex + 1
msg = 'Title: ' + rowSelected.cells[0].innerHTML;
msg += '\r\nDescription: ' + rowSelected.cells[1].innerHTML;
msg += '\n\nLink: ' + rowSelected.cells[2].innerHTML;
msg += '\nPublication Date: ' + rowSelected.cells[3].innerHTML;
navigator.clipboard.writeText(msg);
}
}
}
At the end of the html I call the function. The HTML contains 3 tables and this enabled me to click on any table, highlight the row, and copy the correct range of cells.

Jquery .each not working for first row from the table

I am using jquery .each to loop the values and push in JSON. it is working for all the rows leaving the first row.
for (j = 0; j < parsedResult.length; j++) {
var pack_id = parsedResult[j].pack_id;
var pack_dsc = parsedResult[j].pack_dsc;
var pack_base_amount = parsedResult[j].pack_base_prc;
var pack_tax_amount = parsedResult[j].pack_tax_amt;
var pack_grand_total = parsedResult[j].pack_grand_total;
row += "<span id='single_pack_details'><span id='pack_id' class='hidden'>" + pack_id + "</span><b>Pack description: </b><span id='pack_dsc'>" + pack_dsc + "</span><b>Pack Amount:</b> ₹ <span id='pack_grand_total'>" + pack_grand_total + "</span></div><span class='hidden' id='pack_base_amount'>" + pack_base_amount + "</span><span class='hidden' id='pack_tax_amount'>" + pack_tax_amount + "</span></span>";
}
Below is where i trying to put it in a loop and pushing to pack_details object
$(this).closest("tr").find('#single_pack_details').each(function () {
var obj = {
pack_id: $(this).closest("span").find("#pack_id").text(),
pack_dsc: $(this).closest("span").find("#pack_dsc").text(),
pack_grand_total: $(this).closest("span").find("#pack_grand_total").text(),
pack_base_amount: $(this).closest("span").find("#pack_base_amount").text(),
pack_tax_amount: $(this).closest("span").find("#pack_tax_amount").text()
}
pack_details.push(obj);

How to optimize jquery script (table creation N rows X 56 cols)

Hi I have a jquery scripts that takes table template and adds N rows (N=[1...100]) as clones of first TR. then each cell in each row is populated with some data (not all cells are always filled), each cell has " on clik " event attached, and on cell hover row, cell, coll is highlighted.
The problem i am facing is the optimization of generation (time) and usability (the mouse movemnts aren't smooth)
the code:
HTML template table:
<table id='schedulerview' class='myGrid'>
<colgroup id='col_0'></colgroup>
<colgroup id='col_1'></colgroup>
<colgroup id='col_2'></colgroup>
<colgroup id='col_3'></colgroup>
....
<colgroup id='col_55'></colgroup>
<thead>
<tr>
<th>0</th>
<th>1</th>
<th>2</th>
<th>3</th>
....
<th>51</th>
</tr>
</thead>
<tbody>
<tr id='template' style='display:none'>
<td id='0' HID='W0_Y_I' class='scheddata'>Week 1</td>
.....
<td id='51' HID='W55_Y_I' class='scheddata'>Week 52</td>
</tr>
</tbody>
</table>
CSS :
.litrow { background-color: #eee; }
.litcell { background-color: yellow; }
file codebehind.js
$(document).ready(function () {
//turn on row, cell, column highlight on hover
$("table#schedulerview tbody").on('mouseenter', 'tr', function () {
$(this).addClass('litrow');
});
$("table#schedulerview tbody").on('mouseleave', 'tr', function () {
$(this).removeClass('litrow');
});
$("table#schedulerview tbody").on('mouseenter', 'td', function () {
$(this).addClass('litcell');
$("colgroup").eq($(this).index()).addClass("litrow");
});
$("table#schedulerview tbody").on('mouseleave', 'td', function () {
$(this).removeClass('litcell');
$("colgroup").eq($(this).index()).removeClass("litrow");
});
//function for getting data and create schedule table from template table
getSchedule();
});
getschedule function:
function getSchedule() {
var data = "{userid:'" + userid + "',year:" + year + "}";
$.ajax({
type: "POST",
url: "/Scheduler.aspx/getSchedule",
data: data,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (ret) {
var areas = JSON.parse(ret.d.Areas);
var schedule = JSON.parse(ret.d.Schedule);
//remove all rows from table that are not template
$('table#schedulerview tr.eventSchedule').remove();
//create row for each element from DB - prepare matrix elementsXWeeks
var $tr = $('#template');
$.each(areas, function (i, x) {
var $clone = $tr.clone();
$clone.css('display', 'block');
$clone.attr('id', 'new_row_' + i);
$clone.addClass('eventSchedule');
$clone.children('td:first').text(x.AreaName);
//for each cell in new row
$clone.children('td.scheddata').each(function () {
var $this = $(this);
var HID = $this.attr("HID").replace('_Y_', '_' + year + '_').replace('_I', '_' + x.IDObszaru);
$this.attr("HID", HID);
});
$tr.before($clone);
});
//fill in the matrix with scheduled data
$.each(schedule, function (i, x) {
$td = $("table#schedulerview td[HID='" + x.HID + "']");
$td.addClass(x.Status);
$td.attr("WeekNum", x.WeekNum);
$td.attr("PlanID", x.Id);
$td.parent().addClass('plannedrow');
});
},
error: function (ret) {
alert(ret.responseText);
}
});
}
The getSchedule() function lasts few seconds, is it possible to optimize it so it would be faster?
CHANGES:
I've tried different approach for row creation:
for (i = 0; i < areas.length; i++) {
$lasttr = $("table#schedulerview tbody").append("<tr id='new_row_" + i + "' class='eventSchedule' ></tr>");
$lasttr = $("table#schedulerview tbody tr#new_row_" + i);
for (j = 0; j < 56; j++) {
var sclass = "";
if (j == 0)
$lasttr.append("<td>" + areas[i].AreaName + "</td>");
if (j == 1)
$lasttr.append("<td>" + areas[i].AreaSubName + "</td>");
if (j == 2)
$lasttr.append("<td>" + areas[i].AreaParentName + "</td>");
if (j > 2) {
sclass = "'scheddata'";
k = j - 2;
$lasttr.append("<td class=" + sclass + " HID='W" + k + "_" + year + "_" + areas[i].AreaID + "'></td>");
}
}
}
but it's not fast enough- and the problem with hovering remains. (also when using css :hover pseudoclass.

Can you do something like this?
$(function () {
for (i = 0; i < 56; i++)
$("thead tr").append("<th>" + (i+1) +"</th>");
for (i = 0; i < 20; i++){
$("tbody").append("<tr />");
for (j = 0; j < 56; j++)
$("tbody tr:last-child").append("<td>" + ((i+1) + ": " + (j+1)) +"</td>");
}
});
table tr:hover td {background: #99f;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

creating a html table in javascript

I want to create HTML table in java script. Inside a for loop I want to create a dynamic table which can be extended. This is how I am it using now:
function(json)
{
var content= $('#name1').html('').append('<td> Name: ' + json.name + '<td>');
var content= $('#address1').html('').append('<td> address: ' + json.address + '<td>');
var content= $('#age1').html('').append('<td> age: ' + json.age + '<td>');
var content= $('#status1').html('').append('<td> status: ' + json.status + '<td>');
}
HTML file is
<table>
<tr id="name1"></tr>
<tr id="address1"></tr>
<tr id="age1"></tr>
<tr id="status1"></tr>
</table>
now it is just with hardcore values but I want it auto generated and insert more rows if neccessary...

remove id from tr. Because if you need multiple row then id will be duplicated which is not valid.
<table id="mytable">
</table>
function(json)
{
for(i=0;i<json.length;i++){
var newRow= $("<tr></tr>");
newRow.append('<td> Name: ' + json[i].name + '<td>');
newRow.append('<td> address: ' + json[i].address + '<td>');
newRow.append('<td> age: ' + json[i].age + '<td>');
newRow.append('<td> status: ' + json[i].status + '<td>');
$("#mytable").append(newRow);
}
}

i think this will help you
function(json)
{
for(i=0;i<jsn.length;i++){
$('#YOUR_TABLE_ID').append("<tr><td>"+ json.name+"</td></tr>")
}
}

<table id="mytable">
<tr id="name1"><td></td></tr>
</table>
if (results != null && results.length > 0) {
// Build our table header
var content = "";
for(i=0;i<data.length;i++)
{
content += '<tr>';
content += '<td></td>'
}
content += '</tr>';
}
$("#mytable tbody").append(content);
}

You can Use Append Method to create Rows in a table like
for(i=0;i<data.length;i++)
{
$("YOUR_TABLE_ID").append("<tr><td>"+data[i]['name']+"</td><td>"+data[i]['address']+"</td><td>"+data[i]['age']+"</td><td>"+data[i]['status']+"</td></tr>");
}

I'm not clear with your requirement but i can provide you some basic code hope that helps you.
var jsonList = [{name:'Jhon',address:'Jhon Address goes here',age:'27',status:'Single'},
{name:'Smith',address:'Smith Address goes here' ,age:'32', status:'Single' }];
function createTable(){
var table = '<table>';
for(var ind=0;ind< jsonList.length;ind++)
table += fetchRowInformation(jsonList[ind]);
console.log(table+'</table>');
}
function fetchRowInformation(json){
return '<tr><td> Name: ' + json.name + '<td>'+'<td> address: ' + json.address + '<td>'+ '<td> age: ' + json.age + '<td>'+'<td> status: ' + json.status + '<td></tr>';
}
JS Fiddle Demo

function tableCreate(rows, columns) {
var body = document.body
tbl = document.createElement('table');
tbl.style.width = '20%';

get text from attribute and format it

I have a div elements with data-seat and data-row property:
<div class='selected' data-seat='1' data-row='1'></div>
<div class='selected' data-seat='2' data-row='1'></div>
<div class='selected' data-seat='3' data-row='1'></div>
<div class='selected' data-seat='1' data-row='2'></div>
<div class='selected' data-seat='2' data-row='2'></div>
I want print friendly message for selected seats:
var selectedPlaceTextFormated ='';
$(".selected").each(function () {
var selectedPlace = $(this);
selectedPlaceTextFormated += "Row " + selectedPlace.attr("data-row") + " (seat " + selectedPlace.attr("data-seat") + ")\n";
});
alert(selectedPlaceTextFormated);
This code works well and shows the following:
Row 1 (seat 1)
Row 1 (seat 2)
Row 1 (seat 3)
Row 2 (seat 1)
Row 2 (seat 2)
But, I want group seats by row, i.e I want the following:
Row 1(seats: 1,2,3)
Row 2(seats: 1,2)
also, order by row number. How can I do this?
Thanks. DEMO

Here is the code
var selectedPlaceTextFormated ='';
var row_array = [];
$(".selected").each(function () {
var selectedPlace = $(this);
if (!row_array[selectedPlace.attr("data-row")]){
row_array[selectedPlace.attr("data-row")] = selectedPlace.attr("data-seat");
}
else row_array[selectedPlace.attr("data-row")] += ','+selectedPlace.attr("data-seat");
});
for (row in row_array){
alert("Row "+ row +"(seat " + row_array[row] + ")\n" );
}
And here the link to the working fiddle: http://jsfiddle.net/3gVHg/

First of all, jQuery is kind enough to automatically grab data- attributes into its data expando object, that means, you can access those data via:
jQueryObject.data('seat');
for instance.
Your actual question could get solved like
var $selected = $('.selected'),
availableRows = [ ],
selectedPlaceTextFormated = '',
currentRow,
currentSeats;
$selected.each(function(_, node) {
if( availableRows.indexOf( currentRow = $(node).data('row') ) === -1 ) {
availableRows.push( currentRow );
}
});
availableRows.forEach(function( row ) {
selectedPlaceTextFormated += 'Row ' + row + '(';
currentSeats = $selected.filter('[data-row=' + row + ']').map(function(_, node) {
return $(this).data('seat');
}).get();
selectedPlaceTextFormated += currentSeats.join(',') + ')\n';
});
jsFiddle: http://jsfiddle.net/gJFJW/3/

You need to use another variable to store the row, and format accordingly.
var selectedPlaceTextFormated ='';
var prevRow = 0;
$(".selected").each(function () {
var selectedPlace = $(this);
var row = selectedPlace.attr("data-row");
var seat = selectedPlace.attr("data-seat");
if(prevRow == row){
selectedPlaceTextFormated += "," + seat;
}
else{
if(selectedPlaceTextFormated != ''){
selectedPlaceTextFormated += ')\n';
}
selectedPlaceTextFormated += "Row " + row + " (seat " + seat;
prevRow = row;
}
});
selectedPlaceTextFormated += ')\n';
alert(selectedPlaceTextFormated);
Check http://jsfiddle.net/nsjithin/R8HHC/

This can be achieved with a few slight modifications to your existing code to use arrays; these arrays are then used to build a string:
var selectedPlaceTextFormated = [];
var textFormatted = '';
$(".selected").each(function(i) {
var selectedPlace = $(this);
var arr = [];
selectedPlaceTextFormated[selectedPlace.attr("data-row")] += "," + selectedPlace.attr("data-seat");
});
selectedPlaceTextFormated.shift();
for (var i = 0; i < selectedPlaceTextFormated.length; i++) {
var arr2 = selectedPlaceTextFormated[i].split(",");
arr2.shift();
textFormatted += "Row " + (i + 1) + " seats: (" + arr2.join(",") + ")\n";
}
alert(textFormatted);
​
Demo

I'd just do this:
var text = [];
$(".selected").each(function () {
var a = parseInt($(this).data('row'), 10),
b = $(this).data('seat');
text[a] = ((text[a])?text[a]+', ':'')+b;
});
var selectedPlaceTextFormated ='';
$.each(text, function(index, elem) {
if (!this.Window) selectedPlaceTextFormated += "Row " + index + " (seat " + elem + ")\n";
});
alert(selectedPlaceTextFormated);
