Selecting elements great grand children by jquery and changing its width - javascript

I need to select an element <th>A</th> in a table whose path is *[#id="something"]/table/thead/tr/th[2] and change its width.
(function ITPscript() {
$(document).ready(function() {
$("#something table thead tr:nth-child(2)").width(1000);
});
})();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="something" class="aaa">
<table class="sortable">
<thead>
<tr>
<th>0</th>
<th>A</th>
<th>B</th>
<th>C</th>
<th>D</th>
<th>E</th>
<th>F</th>
<th>G</th>
<th>H</th>
<th>I</th>
<th>J</th>
<th>K</th>
<th>L</th>
<th>M</th>
<th>N</th>
<th>O</th>
</tr>
</thead>
<tbody id="aBody">
<tr>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>
<td>1</td>

</tr>
</tbody>
<tfoot></tfoot>
</table>
</div>
I'm using $("#something table thead tr:nth-child(2)").width(140); but its not working. Need a proper way to select the element.


:nth-child does not select the nth child of the element, it selects the element which is the nth child of its parent. The selector needs to be ... tr th:nth-child(2):
(function ITPscript() {
$(document).ready(function() {
$("#something table thead tr th:nth-child(2)").width(1000);
});
})();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="something" class="aaa">
<table class="sortable">
<thead>
<tr>
<th>0</th>
<th>A</th>
<th>B</th>
<th>C</th>
<th>D</th>
<th>E</th>
<th>F</th>
<th>G</th>
<th>H</th>
<th>I</th>
<th>J</th>
<th>K</th>
<th>L</th>
<th>M</th>
<th>N</th>
<th>O</th>
</tr>
</thead>
<tbody id="aBody">

Alternate Table Row Background Color Based on Column Value Changing

I'm reading data into an html table from a database and would like to alternate the row color when the value in the first column changes -- nothing fancy just alternate between two colors to help visually group the data. The issue I'm having is the groups of data is dynamic, and I don't know how to change the colors based on dynamic data. I'm open to use CSS, jquery, javascript -- whatever tricks you have that would work. I've created a very simple jsFiddle that has all rows the same color for you to play with.
UPDATED EXPLANATION:
When I say I want the row colors to alternate based on the value of a column changing, what I mean is, when looking at my fiddle example, the table rows start off aliceblue, and the value in the first column is 1. When that value changes to 2 I want the table rows to change colors to lightgreen. When the Key column value then changes to 3 I want the colors to switch back to aliceblue. When the key column value changes to 4 I want it to flip back to light green. Hope this helps to clarify...
As always, any help you can give would be greatly appreciated!!
tbody tr {
background: aliceblue;
}
.altColor {
background: lightgreen;
}
<div id="banner-message">

I have added some javascript logic to make it work. I have added two scenarios. One if class should be based on the Odd/Even values and another is if class should be based on the value change.
See the Snippet below:
$(document).ready(function(){
$("#banner-message tbody tr").each(function() {
if(parseInt($(this).find("td").first().html()) % 2 == 0){
$(this).addClass("altColor");
}
});
let prevValue = parseInt($("#banner-message2 tbody tr").first().find("td").first().html());
let currentClass = '';
$("#banner-message2 tbody tr").each(function() {
if(prevValue != parseInt($(this).find("td").first().html())){
(currentClass=='')?currentClass = 'altColor':currentClass='';
}
$(this).addClass(currentClass);
prevValue = parseInt($(this).find("td").first().html());
});
});
tbody tr {
background: aliceblue;
}
.altColor {
background: lightgreen;
}
div {
display:inline-block;
padding:10px;
}

I hope this will help you :)

You can alternate color on a table with the :nth-child selector and the odd and even rules.
More can be found there https://www.w3.org/Style/Examples/007/evenodd.en.html
Try something like this:
tr:nth-child(even) {background: #CCC}
tr:nth-child(odd) {background: #FFF}

If you want to get the whole string in column use
$(document).ready(function(){
//let prevValue = parseInt($("#banner-message2 tbody tr").first().find("td").first().html());
let prevValue = $("#banner-message2 tbody tr").find("td:first").html();
console.log(prevValue);
let currentClass = '';
$("#banner-message2 tbody tr").each(function() {
if(prevValue != $(this).find("td:first").html()){
(currentClass=='')?currentClass = 'altColor':currentClass='';
}
$(this).addClass(currentClass);
prevValue = $(this).find("td:first").html();
});
});

Hide the scrollbar with scrolling enabled

In the below code I have two blocks, of those I'm maintaining the scroll position of the left block when I scroll the right one. Here I just want to hide the scrollbar of the left block.
Any help would be great.
$(function() {
$('#two').scroll(function() {
var bodyScrollTop = $(this).scrollTop();
$('#one').scrollTop(bodyScrollTop);
});
});
td{
width:50px;
}
.one, .two{
height:120px;
width:200px;
overflow-y:auto;
}
.one{
float:left;
}

Use the overflow property:
.one {
float: left;
overflow: hidden;
}
Example:
$(function(){
$('#two').scroll(function(){
var bodyScrollTop = $(this).scrollTop();
$('#one').scrollTop(bodyScrollTop);
});
});
td{
width:50px;
}
.one, .two{
height:120px;
width:200px;
overflow-y:auto;
}
.one{
float:left;
overflow: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="one" id="one">

<tr><td>1</td><td>1</td><td>1</td><td>1</td></tr>

</div>
<div class="two" id="two">
<table border="1">
<tr><td>1</td><td>1</td><td>1</td><td>1</td></tr>
<tr><td>1</td><td>1</td><td>1</td><td>1</td></tr>
<tr><td>1</td><td>1</td><td>1</td><td>1</td></tr>
<tr><td>1</td><td>1</td><td>1</td><td>1</td></tr>
<tr><td>1</td><td>1</td><td>1</td><td>1</td></tr>

You can just make overflow-y:hidden for .one class, since you are scrolling it programmatically.
.one{
float:left;
overflow-y:hidden;
}
$(function(){
$('#two').scroll(function(){
var bodyScrollTop = $(this).scrollTop();
$('#one').scrollTop(bodyScrollTop);
});
});
td{
width:50px;
}
.one, .two{
height:120px;
width:200px;
overflow-y:auto;
}
.one{
float:left;
overflow-y:hidden;
}

Re-apply css rules for first visible row on table

I am trying to change css style for the first visible row on a table using jQuery and css rules.
When i change the offset i would like to show first visible table TBODY row in red using my css rule.
this is my code example :
$(document).ready(function(){
$('input').on('change',function(){
$.each($("tbody>tr"), function(index, element) {
offset = $('input').val();
if(index < offset){
$("#row-"+index).removeClass('is-visible');
}else{
$("#row-"+index).addClass('is-visible');
}
});
})
});
table tbody>tr{
display:none;
}
table tbody>tr.is-visible{
display:block;
}
table tr.is-visible:first-child{
background-color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
offset : <input type="number" min="0" max="100">
<hr>
<table class="table">

Thanks for your help.

Through Pure css it's not possible:- Targeting first visible element with pure CSS
But through jQuery you can do like below:-
$(document).ready(function(){
$('input').on('change',function(){
$.each($("tbody>tr"), function(index, element) {
offset = $('input').val();
if(index < offset){
$("#row-"+index).removeClass('is-visible');
}else{
$("#row-"+index).addClass('is-visible');
}
});
$(".is-visible:first").css({"background-color":"red"});
$(".is-visible").not(":first").css({"background-color":"#ffffff"});
})
});
table tbody>tr{
display:none;
}
table tbody>tr.is-visible{
display:block;
}
table tr.is-visible:first-child{
background-color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
offset : <input type="number" min="0" max="100">
<hr>
<table class="table">
<thead>
<tr>
<th>TH 1</th>
<th>TH 2</th>
<th>TH 3</th>
</tr>
</thead>
<tbody>
<tr class="is-visible" id="row-0">
<td>0</td>
<td>0</td>
<td>0</td>
</tr>
<tr class="is-visible" id="row-1">
<td>1</td>
<td>1</td>
<td>1</td>
</tr>
<tr class="is-visible" id="row-2">
<td>2</td>
<td>2</td>
<td>2</td>
</tr>
<tr class="is-visible" id="row-3">
<td>3</td>
<td>3</td>
<td>3</td>
</tr>
<tr class="is-visible" id="row-4">
<td>4</td>
<td>4</td>
<td>4</td>
</tr>
<tr class="is-visible" id="row-5">
<td>5</td>
<td>5</td>
<td>5</td>
</tr>
</tbody>
</table>

You have to do using jQuery. Try below code.
$(document).ready(function(){
$('input').on('change',function(){
$.each($("tbody>tr"), function(index, element) {
offset = $('input').val();
if(index < offset){
$("#row-"+index).removeClass('is-visible');
}else{
$("#row-"+index).addClass('is-visible');
}
$(".is-visible").css({"background-color":"white"});
$("#row-"+offset).css({"background-color":"red"});
});
})
});
table tbody>tr{
display:none;
}
table tbody>tr.is-visible{
display:block;
}
table tr.is-visible:first-child{
background-color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

JS/HTML - .SlideToggle two tables next to each other

I have two tables with different heights next to each other. I would like the tables to slideToggle independently.
When selecting the table headers, currently nothing is happening...
The fiddle: http://jsfiddle.net/wod51fvL/
Any comments welcomed!
The HTML:
<h1>Test Heading 1</h1>
<table>
<tr>
<td valign="top">
<table class="tableSort">
<thead>
<tr>
<th id="clientClick" colspan="3" style="cursor:pointer;">Client</th>
</tr>
</thead>
<div id="clientResult">
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
</div>
</table>
</td>
<td valign="top">
<table class="tableSort">
<thead>
<tr>
<th id="employeeClick" colspan="3" style="cursor:pointer;">Employee</th>
</tr>
</thead>
<div id="employeeResult">
<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>
</div>
</table>
</td>
</tr>
</table>
The JS:
var j$ = jQuery.noConflict();
j$(document).ready(function () {
j$("#clientClick").click(function () {
j$("#clientResult").slideToggle(600);
});
});
j$(document).ready(function () {
j$("#employeeClick").click(function () {
j$("#employeeResult").slideToggle(600);
});
});

A very bad html and js
You can't wrap tr tags into div.
You don't need to call document.ready function twice
Here is a quick jsfiddle to fit your example. It needs to be improved(no time sorry).
http://jsfiddle.net/wod51fvL/7/
$(document).ready(function () {
$("#clientClick").click(function () {
$("#clientResult").slideToggle(600);
});
$("#employeeClick").click(function () {
$("#employeeResult").slideToggle(600);
});
});
