adjusting table content with javascript by enumerating rows
<p>I have a table row with 4 columns on my ecommerce site and I want to replace the content of 1st column if total amount in last column (TD class "total") is over 10 EUR.</p>

<p>How can I do this with javascript only, I guess somehow to enumerate through the table rows and look for a correct row (one with the last column class as total) and then access the content of 1st column on this row but how?</p>
