Javascript : find first unchecked box and retrieve information from row
<p>So I am trying to find a way to extract data from the first row where the checkbox from the first column is unchecked. I know this may sound like a true beginner question but I couldn't manage to find how to do it despite searching for quite a few hours. </p>

<p>Here a step-by-step of my goal to clarify :</p>

<ol>
<li>Find the first checkbox which is unchecked;</li>
<li>Retrieve information from another column (inner html) but from the corresponding row <strong>and</strong> an attribute ("name") of the checkbox;</li>
<li>Without opening it on-screen, use the attribute of the checkbox (partial URL) to open completed URL and retrieve more information into MySQL;</li>
<li>Check the checkbox;</li>
<li>Rince and repeat </li>
</ol>

<p>I am only looking for info concerning step one and two, the rest is there for clarification. I do not have prior experience in Javascript writing prior my last few days of Internet browsing, the only coding I've done were statistical analysis in R. </p>

<p>Any help would be highly appreciated.</p>

<p>Thank you very much!</p>
