Find td with specific text, and operate on the td right after that one?

Answer 1

First, you want to use :contains:

jQuery( "td:contains(text)" );

Then, you can use .next and .append:

jQuery( "td:contains(text)" ).next().append("Hello");

Here's a working snippet to demonstrate usage:

jQuery(function($) {
  $("td:contains(Text to Find)").next().append(" Hello");
});

table {
  border-collapse: collapse;
}

td {
  border: 1px solid #ccc;
  padding: 2px 5px;
}
