jquery recognize in which row iam

I have a table with thousands of rows. There are no ids and so on.

Within the tds of the rows I have a link calling a function and passing "this" to get the link object.

Using jQuery it is easy to get the the closest tr and table (and so the tables.rows.length)

  1. I want to know as easy in which row I am. OK I could do a loop but does exist any easier possibility?
#

Another table with rows
The rows have mixing className in no structured order tr1 tr2, tr4 maybe clsA, tr3 clsB and between them are non "class-named" trs or some called separator

  1. I want to know which row comes first clsA or clsB -> remember it is not the first sibling etc. there can be empty trs or separator.

-> I want to avoid loops, that's why I ask for some jQuery tricks.

You don't need to use jQuery to get row's index. There's DOM property 'rowIndex' (which is the fastest way to get row index IMO). See more here http://www.w3schools.com/htmldom/prop_tablerow_rowindex.asp

$("#TableId td").click(function()
{   
  var index = $(this).parent("tr")[0].rowIndex;
  alert(index);
});

If you have an id on the table you can use this:

$("#TableId td").click(function()
{   
  var index = $("#TableId tr").index(this.parent("tr"));
});

Read more about the index method at http://docs.jquery.com/Core/index
