Question

I am trying to navigate a table row that has been clicked, to extract data from other parts of the row.

this is the HTML snippet of the row that was clicked on:

<tr><td class=" sorting_1">Foobar</td>
    <td>Hello</td><td><a href="/some/path/abc.html">42</a></td>
    <td>0</td>
    <td><img src="/images/img.gif"></td>
    <td>7:44 AM</td>
    <td><ul><li><a href="/path2/read/3">Read it</a></li>
            <li><a class="booboo" href="#">Just do it</a></li>
        </ul></td>

The cell element that was clicked on has class “booboo”.

I want to be able to select the following data:

• the id used in the url of the previous li a sibling (it is 3 in the example given above)
• the name in the first column (it is ‘Foobar’ in the example given)
• the url of the anchor elem in the 2nd cell (should be /some/path/abc.html in this example)

Can anyone point out the functions required to navigate a table row, preferably with a snippet showing how to select the values in the sample snippet shown above?

No hill for a climber…

$("table a.booboo").click(function() {
    var $this = $(this);
    var tr = $this.closest("tr"); 

    // the id used in the url of the previous li a sibling
    var a = $this.closest("ul").find("li:first a").attr("href");
    a = a.substring(a.lastIndexOf("/") + 1);
    alert(a);

    // the name in the first column
    var b = tr.find("td:first").text();
    alert(b);

    // the url of the anchor elem in the 2nd cell
    var c = tr.find("td:eq(2) a").attr("href");
    alert(c);
});
