using each() from a tr, get the 1st child's alt text

using each() from a tr, get the 1st child's alt text


Hey guys, first post here!

Javascript/PHP developer working my way through jQuery, now wondering how I lived without it.

I'm trying to get append() another column to each <tr> in a table. So I need somethings to do this append, which is very easy.

The code I'm struggling with is this:
  1. $(".my_tr").each(function(index,value){
               
                    // get the group ID and index
                    var grpId = $(".my_first_td").get(index).attr('id'); 


It says attr() is not a function.

I'm using $.dump() and without the attr() I do get the <td> elements (the first <td> in every row in my case)

How do you get attributes from an object?

I've also found out that "value" and "this" are equal to the <tr> object, which I can use to get the first_child... but even then attr() didn't work.

Thanks for any help. I hope I made myself clear.
