Here's a unique version: "A guide on using jQuery to dynamically adjust the background color of table

I need some assistance with changing the background color of td elements based on the th class. Specifically, I want to target all td elements under the bots class in the HTML code provided below.

<table border="1" class="CSSTableGenerator" id="myTable">
  <tr>
    <th>Component</th>
    <th>Properties</th>
    <th class="bots">J10</th>
    <th>J11</th>
    <th>J12</th>
    <th>J13</th>
  </tr>
  <tr>
    <td>GenerateAlternateTagUrlDroplet</td>
    <td>alternateTagConfiguration</td>
    <td class="trueValue">/com//jec/website/seo/</td>
    <td class="trueValue">/com//jec/website/seo/</td>
    <td class="trueValue">/com//jec/website/seo/</td>
    <td class="trueValue">/com//jec/website/seo/</td>
  </tr>
  <tr>

    <td>AlternateTagUrlDroplet</td>
    <td>tagConfiguration</td>
    <td class="trueValue">/jec/website/seo/</td>
    <td class="trueValue">/jec/website/seo/</td>
    <td class="trueValue">/jec/website/seo/</td>
    <td class="trueValue">/jec/website/seo/</td>
  </tr>
</table>

If someone could provide me with a jQuery code solution for this challenge, it would be greatly appreciated.

Thank you in advance for your help!

Answer №1

To highlight specific columns in a table using jQuery, you can utilize the map() function to create an array of indexes for columns with a certain class (in this case, .bots). You can then iterate over each td element in the table and apply CSS style changes based on whether the column index matches one in the array. 

var bots = $('tr th.bots').map(function() {
  return $(this).index();
}).get()

$('tr:not(:first) td').each(function() {
  if (bots.indexOf($(this).index()) != -1) $(this).css('background', 'blue')
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table border="1" class="CSSTableGenerator" id="myTable">
  <tr>
    <th>Component</th>
    <th>Properties</th>
    <th class="bots">J10</th>
    <th>J11</th>
    <th class="bots">J12</th>
    <th>J13</th>
  </tr>
  <tr>
    <td>GenerateAlternateTagUrlDroplet</td>
    <td>alternateTagConfiguration</td>
    <td class="trueValue">/com//jec/website/seo/</td>
    <td class="trueValue">/com//jec/website/seo/</td>
    <td class="trueValue">/com//jec/website/seo/</td>
    <td class="trueValue">/com//jec/website/seo/</td>
  </tr>
  <tr>
    <td>AlternateTagUrlDroplet</td>
    <td>tagConfiguration</td>
    <td class="trueValue">/jec/website/seo/</td>
    <td class="trueValue">/jec/website/seo/</td>
    <td class="trueValue">/jec/website/seo/</td>
    <td class="trueValue">/jec/website/seo/</td>
  </tr>
</table>

Answer №2

To achieve this, one possible approach could be:

Code Example

const index = $('.robots').index() + 1; // Increment by 1 to adjust for zero-based indexing
$("td:nth-child(" + index + ")").css("background", 'yellow');

Answer №3

To add color to the tds based on the index of th.bots, you can use the following jQuery code:

$('th.bots').each(function(){
    $('td:nth-child('+($(this).index() + 1)+')').css('background-color', 'blue');
});

Note: This code excludes other tables on the same page. You can see a working example here: http://codepen.io/anon/pen/PzNZrE

$('th.bots').each(function(){
    $(this).parents('table').children().find('td:nth-child('+($(this).index() + 1)+')').css('background-color', 'blue');
});
