Sophisticated spreadsheet - Pinpointing particular <TR>

With my current setup, I have a complicated table that results in a simple layout. Unfortunately, changing the HTML output is not an option for me right now. So, I am experimenting with jQuery:

<div id="contentDiv" class="mainContent">
  <table cellspacing="0" border="0" width="100%">
   <tr>
     <td>
       <table width="100%" BORDER=1 cellpadding=0 cellspacing=0 style="padding: 5px 10px 10px 10px;">
         <tr>
           <TD STYLE="BACKGROUND: RED;" WIDTH="70%">

Currently, I'm focusing on modifying the source code (check final line above) where I've manually set BACKGROUND: RED;

Is there a way to add a class to that TD element when the page loads so that I can apply other styles through CSS? I believe jQuery will come to my rescue here :)

Maybe something like this:

$table.find('.contetentDiv table table td').removeClass('sorted')

????

Answer №1

Here's a nifty solution:

$(function() {
    $('#contentDiv table table td:first').addElement('newClass');
});

You can now style your elements using the .newClass in your CSS. This snippet ensures that the class is applied only to the first td element.

Answer №2

<div id="contentDiv" class="mainContent">
  <table cellspacing="0" border="0" width="100%">
   <tr>
     <td>
       <table width="100%" BORDER=1 cellpadding=0 cellspacing=0 style="padding: 5px 10px 10px 10px;">
         <tr>
           <TD class="makeItRed" WIDTH="70%">

Consider trying out the following:

$(document).ready(function(){ 
      $('makeItRed').addClass('makeItBlue');
      $('td:contains("TestData")').addClass('makeItGreen'); 
    });

Answer №3

Experiment with this code snippet to see if it fits your requirements:

jQuery("#contentDiv").find("table tr td").each(function(){
   $(this).find("table tr td").each(function(){
      $(this).css("background", "blue");
   });
});
