Get href attribute on jQuery

Question

I have some table rows

<tr class="b_row">
    <td>
        <div class="cpt">
            <h2>
                <a href="/ref/ref/1.html">example</a>
            </h2>
        </div>
    </td>
</tr>

<!--more elements -->

<tr class="b_row">
    <td>
        <div class="cpt">
            <h2>
                <a href="/ref/two/23.html">example N</a>
            </h2>
        </div>
    </td>
</tr>

I need to get hyperlinks in attribute. I use this script

function openAll()
{
    $("tr.b_row").each(function(){
    var a_href = $('div.cpt').find('h2 a').attr('href');
    alert ("Href is: " + a_href);
}

Problem: variable a_href is always / ref/ref/1.html

Answer 1

In loop you should refer to the current procceded element, so write:

var a_href = $(this).find('div.cpt h2 a').attr('href'); 

Answer 2

var a_href = $('div.cpt').find('h2 a').attr('href');

should be

var a_href = $(this).find('div.cpt').find('h2 a').attr('href');

In the first line, your query searches the entire document. In the second, the query starts from your tr element and only gets the element underneath it. (You can combine the finds if you like, I left them separate to illustrate the point.)
