How to keep adding data to next table column - javascript

This Fiddle Example shows a comparison table that dynamically shows information in a column when a button is clicked. Once the table is filled up, I want to start the whole process again. But as the example shows, the buttons are stuck at adding information to th:nth-child(2) and td:nth-child(2) during the second time instead of moving on to the next column like during the first time.
I'm guessing this part needs some change if( allCells === fullCells ) { to keep information being added to next columns.

Code:

$('.area').each(function(){
var area = $(this),
filltable ='',
button = $(this).find('button'),
buttontext = button.text();
button.on("click",function(){
var allCells = $('table').find('th,td').length;
var fullCells = $('table').find('th,td').filter(function() {
return $(this).text() != '';
}).length;
if( allCells === fullCells ) { // If table is full
$('table').find('th,td').not(':first-child').removeClass('addinfo');
filltable();
}
else { // If table isn't full
filltable = function(){
var i = $('th.addinfo').length !== 0 ? $('th.addinfo:last').index() : 0;
console.log( i );
i + 2 > $('th').length ||
$('th,td').filter(':nth-child(' + (i + 2) + ')')
.addClass( 'addinfo' ).html(buttontext);
}
filltable();
}
}); // end button on click function
});
});

Please see the attached link for demo. I have created a function name cleartable() which clears the table if its full and have used your old filltable() function to repopulate. There is repetition of code which you will have to clean up.
th:nth-child(2) identifies second child of th.
td:nth-child(2) identifies second column.
Similarly if you wanted to do something with let say second row, you can use tr:nth-child(2).
I hope this helps you understand a little about parent-child relationship in jquery.
JSFIDDLE DEMO
function clearTable() {
$('table th:nth-child(2)').html('');
$('table th:nth-child(3)').html('');
$('table th:nth-child(4)').html('');
$('table td:nth-child(2)').html('');
$('table td:nth-child(3)').html('');
$('table td:nth-child(4)').html('');
}

I think you'd better to count th only. count all td and th make me confused.
$(function () {
function filltable(buttontext) {
var i = $('th.addinfo').length !== 0 ? $('th.addinfo:last').index() : 0;
i + 2 > $('th').length || $('th,td').filter(':nth-child(' + (i + 2) + ')')
.addClass('addinfo').html(buttontext);
}
$('.area').each(function () {
var area = $(this),
button = $(this).find('button'),
buttontext = button.text();
button.on("click", function () {
var allCells = $('table').find('th').length-1;
var fullCells = $('table th.addinfo').length;
console.log(allCells, fullCells);
if (allCells === fullCells) { // If table is full
$('table .addinfo').removeClass('addinfo');
filltable(buttontext);
} else { // If table isn't full
filltable(buttontext);
}
});
});

Collapsing and expanding multiple nested rows in jQuery

I need a little help with collapsing and expanding nested rows. Currently my code below expands and collapses as desired at the first level but the subsequent levels also show.
$(document).ready(function(e) {
$('.collapseTitle').click(function() {
$(this).parent()
.parent()
.next('tbody')
.toggleClass('collapsed');
});
});
.collapsed {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<tr>
<td class="collapseTitle">Title</td>
</tr>
</thead>
<tbody class="collapsed">
<tr>
<td>Level 1</td>
</tr>
<tr>
<td>Level 2</td>
</tr>
</tbody>
</table>
I am trying to achieve that Level 1 expands when "collapseTitle" is clicked and that only when "collapseAccount" is clicked, does Level 2 expand. Now I know that my code should look something like the below, but I am struggling...
<table>
<thead>
<tr>
<td class="collapseTitle">Title</td>
</tr>
</thead>
<tbody>
<tr class="collapsed account">
<td class="collapseAccount">Level 1</td>
</tr>
<tr class="collapsed level">
<td>Level 2</td>
</tr>
</tbody>
</table>
<script>
$(document).ready(function(e) {
$('.collapseTitle').click(function() {
$(this).parent().parent().next('tbody tr').toggleClass('account');
});
});
$(document).ready(function(e) {
$('.collapseAccount').click(function() {
$(this).next('tr').toggleClass('level');
});
});
</script>
Any help would be greatly appreciated.
The following code should do it. I hope it helps with what you want to achieve:
collapses/expands columns when clicking on the header/title of the column and
collapses/expands all rows following the account row when clicking on it (until the next account row)
The only thing you need to do is add the class account to the higher level rows. You can do this pretty easily when you're displaying these with a loop.
.collapsed {
/* using visibility, since display causes layout issues */
/* due to empty rows rows/columns collapsing */
visibility: collapse;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<tr>
<td>Title1</td>
<td>Title2</td>
</tr>
</thead>
<tbody>
<tr class="account">
<td class="collapsed">Account Summary - Account A</td>
<td class="collapsed">Account Summary - Account A</td>

</tr>
</tbody>

<script>
$(document).ready(() => {
/* the following handlers expand/collapse the columns */
$('thead > tr > td').each((i, el) => {
$(el).click(() => {
const colIndex = $(el).index() + 1;
const nRows = $('tbody > tr').length;
for (let j = 0; j < nRows; j += 1) {
let cellSelector = `tbody > tr:nth-child(${j+1})`
cellSelector += `> td:nth-child(${colIndex})`;
$(cellSelector).toggleClass('collapsed');
}
})
})
/* the following handlers expand/collapse the account-details rows */
$('tbody > tr.account').each((i, el) => {
$(el).click(() => {
$(el).nextUntil('.account').each((j, ele) => {
$(ele).toggleClass('collapsed');
})
})
})
});
</script>
Your jQuery selectors are just a bit off for the toggleClass. You can use the class names of the row to toggle. Also you should create a class to be toggled that displays the row/hides it. For example:
edit:
I now created the titles and rows dynamically to give you a better idea of how this can be done using data- attributes.
You will have a title td and a row td that match on a data- attribute, so when you click a title and corresponding tr will be shown. So for example if you click title 1 (with a data-index=1) then the tr with the attribute data-rowindex=1 will be shown.
$(document).ready(function(e) {
createTable();
$('.collapseTitle').click(function() {
// grab the data-index value from the clicked title
let index = $(this).attr("data-index");
// find a tr that has the attribute data-rowindex and it matches index
$("tr[data-rowindex='" + index + "']").toggleClass("collapsed");
});
});
function createTable(){
// create the titles and the level rows
for(let i = 0; i < 3; i++){
// create the title row
let $trTitle = $('<tr>');
let $tdTitle = $('<td>', {class: "collapseTitle", text: "Title " + i});
$tdTitle.attr("data-index", i);
let $finalTitleRow = $trTitle.append( $tdTitle );
// create the level row
let $trLevel = $('<tr>', {class: "collapsed account"} );
$trLevel.attr("data-rowindex", i);
let $tdLevel = $('<td>', {text: "Level " + i});
let $finalLevelRow = $trLevel.append( $tdLevel );
// add the title and level row pairs to the head and body
$("#myTableHead").append($finalTitleRow[0]);
$("#myTableBody").append($finalLevelRow[0]);
}
}
.collapsed {
display: none;
}

I managed to find the answer I was looking for... Thank you to "stackoverfloweth",
Answer To My Question
The snippet of code which has helped me thus far is below,
$('.parent-row').click(function(){
var $element = $(this).next();
while(!$element.hasClass('parent-row')){
$element.toggle();
if($element.next().length >0){
$element = $element.next();
}
else{
return;
}
} });
$('.child-row.has-children').click(function(){
var $element = $(this).next();
while($element.hasClass('child-child-row')){
$element.toggle();
if($element.next().length >0){
$element = $element.next();

tr on click change to different tr

Using Jquery, I have a table and on clicking the table row i want td to change to textbox or dropdown.
After entering the values of textbox i want those values to be updated to that table row on which it was clicked. I have got it partially.
Please help me with this.
This is my html code:
<table id="myTable" >
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</table>
This is my script:
$(document).ready(function () {
$("#myTable").children("tbody").children("tr").children("td").click(function () {
$(this.parentNode).replaceWith('<tr><td ><textarea></textarea></td><td ><textarea></textarea></td><td ><textarea></textarea></td></tr>').appendTo($(this)).val().select().blur(function () {
var newText = $(this).val();
$(this).parent().text(newText);
});
});
});
Try something like this. I don't check if it compile, it is just an idea:
$("#myTable").children("tbody").children("tr").children("td").click(function () {
var cell1Text = $(this).find('.cell1').text();
$(this.parentNode).replaceWith('<tr><td><textarea class="cell1">'+cell1Text+'</textarea></td>...</tr>').appendTo($(this)).val().select().blur(function () {
var newText = $(this).val();
$(this).parent().text(newText);
});
})
.blur(function () {
var cell1Val = $(this).find('.cell1').val();
$(this.parentNode).replaceWith('<tr class="cell1">'+cell1Val+'<td ></td>...</tr>').appendTo($(this)).val().select().blur(function () {
var newText = $(this).val();
$(this).parent().text(newText);
});
});

Delete duplicate cells of a one column :html

I am to do the same as per This

Explanation:
$('#test td:first-child') This helps to select only the first Row of the Table
Use this code it is working fine.
var seen = {};
$('#test td').each(function() {
// Encode column and content information.
var key = $(this).index() + $(this).text();
if (seen[key] && $(this).index()==0) {
$(this).text('');

How to find empty table column, including `th` and inject data into it

Updated Fiddle Example:
How would you find an empty table column,including th in the fiddle so that when you click on a button it'll inject data into that column only. For example, when you click on "X" it'll add data to the first empty column,"G" will add data to the second empty....When the table is full, start from the second child column (because the first column is some sort of title column) and replace old data in that column.
Just a guess:
columnTh = $("table th");
columnIndex = columnTh.index() + 1;
columnIndex.each(function(){
if ($(this).html() == '' && $('table tr td:nth-child(' + columnIndex + ')').html() == ''){
// add data
}
But how can I check if the whole table is full so that the button will add data to the first column again?
HTML:
<div class="area">
<select>
<option>Choose</option>
<option>R</option>
<option>T</option>
</select>
<div class="show">
</div>
</div>
<div class="area">
<select>
<option>Choose</option>
<option>X</option>
<option>G</option>
</select>
<div class="show">
</div>
</div>

<tr>

<tr>

<tr>

<td></td>
<td></td>
</tr>
<tr>
<td>Education</td>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td>Language</td>
<td></td>
<td></td>
<td></td>
</tr>
</tbody>
</table>
JS Code
$(function (){
$('.area').each(function(){
var area = $(this),
selectbox = area.find('select'),
show = area.find('.show'),
dialog_open = $(this).find(".dialog_open");
selectbox.change(function(){
selectbox = $(this).find('option:selected').text();
show.html('<button class="dialog_open">'+selectbox+'</button>')
});
var foo = function() {
var dialog_open_text = $(this).find(".dialog_open").text();
$('table td').html(dialog_open_text); // ****Need help in this part*****
};
show.one( "click",dialog_open, foo );
});
});
Here is how to check that the table is full:
var allCells = $('table').find('th,td').length;
var fullCells = $('table').find('th,td').filter(function() {
return $(this).text() != '';
}).length;
if( allCells === fullCells ) { // if true table is full, not full otherwise
//do something table is full
} else {
//table is not full
}
If the first select indicates the column # you're targeting and the second select indicates the content to put in the cells of the column, then you may use the following logic inside the function foo:
var colN = $('select').first().val(),
colCont = $('select').last().val(),
allColumns = $('table').find('th:eq(' + (colN - 1) + '),td:eq(' + (colN - 1) + ')').length,
fullColumns = $('table').find('th:eq(' + (colN - 1) + '),td:eq(' + (colN - 1) + ')').filter(function() { return $(this).text() != ''; }).length;
Then you can check to see if the targeted column is full or not:
if( allColumns === fullColumns ) {
//all cells in target column full
} else {
//not all cells in target column are full
}
You can empty everything but the first column this way:
$('table').find('th,td').not(':first-child').empty();
And here's how to fill a column:
$('td').filter(':nth-child(' + colN + ')').html(dialog_open_text);

Highlight repeating strings

I have up to three almost-identical divs that contain tables of usernames. Some names may be repeated across the three divs. I'd like to highlight the names that are repeated. The first occurrence of the user should not be colored, the second occurrence should have an orange background and the third should have a red background. The divs go from left to right in order so the first div should not have any highlighted usernames.
My HTML looks like:
<div class="col-md-4">
<table class="table table-striped">
<tr>
<th>2/26/2014</th>
</tr>
<tr>
<td>user1</td>
</tr>
<tr>
<td>user2</td>
</tr>
<tr>
<td>user5</td>
</tr>
<tr>
<td>user17</td>
</tr>
</table>
</div>
<div class="col-md-4">
<table class="table table-striped">
<tr>
<th>2/27/2014</th>
</tr>
<tr>
<td>user13</td>
</tr>
<tr>
<td>user5</td>
</tr>
<tr>
<td>user7</td>
</tr>
</table>
</div>
<div class="col-md-4">
<table class="table table-striped">
<tr>
<th>2/28/2014</th>
</tr>
<tr>
<td>user5</td>
</tr>
<tr>
<td>user45</td>
</tr>
<tr>
<td>user1</td>
</tr>
</table>
</div>
I know that the username table cells will be selected with $('table.table td') (if I use jQuery) but I'm not sure what to do from there.
Please let me know if you have any questions.
Thank you.
Is this what you want?
I created a map to store text-occurrence pairs. Each time the text is repeated, the counter associated with it gets incremented. If the counter climbs to a certain value, the background will be set to another color. Give it a shot!
DEMO
var map = new Object();
$('td').each(function() {
var prop = $(this).text()
var bgColor = '#FFFFFF';
if (map[prop] > 1) {
bgColor = '#FF0000';
} else if (map[prop] > 0) {
bgColor = '#FF7F00';
}
$(this).css('background', bgColor);
if (map.hasOwnProperty(prop)) {
map[prop]++;
} else {
map[prop] = 1;
}
});
You could try something like this but I didn't test it
$('td').each(function(){
var text = this.html();
$('td:contains("'+text+'"):nth-child(2)').css({'background':'orange'});
$('td:contains("'+text+'"):nth-child(3)').css({'background':'red'});
});
Edit:
Not particularly elegant but it seems to work
http://jsfiddle.net/63L7L/1/
var second = [];
var third = [];
$('td').each(function(){
var text = $(this).html();
second.push($("td").filter(function() {
return $(this).text() === text;
})[1])
third.push($("td").filter(function() {
return $(this).text() === text;
})[2])
});
$(second).each(function(){
$(this).css({'background':'red'});
});
$(third).each(function(){
$(this).css({'background':'orange'});
});
With pure Javascript (ECMA5)
CSS
.orange {
background-color:orange;
}
.red {
background-color:red;
}
Javascript
Array.prototype.forEach.call(document.querySelectorAll('.table-striped td'), function (td) {
var textContent = td.textContent;
if (this.hasOwnProperty(textContent)) {
td.classList.add(++this[textContent] === 2 ? 'orange' : 'red');
} else {
this[textContent] = 1;
}
}, {});
