[jQuery] Re: selector to return the number of rows in a table before the row I just selected
rowsBefore = row.rowIndex; Ok, but jQuery(#activator + input).parent().parent(); selects the row, but when I try to get rowIndex of that selected row I get undefined back. var trow = jQuery(#activator + input).parent().parent(); alert(trow.attr(class)); // the class of my row alert(trow.rowIndex); // returns undefined. Cheers, Bryan Rasmussen

rowIndex is a DOM property, so you'd have to use alert(trow [0].rowIndex); On Feb 10, 10:19 am, pantagruel rasmussen.br...@gmail.com wrote: rowsBefore = row.rowIndex; Ok, but jQuery(#activator + input).parent().parent(); selects the row, but when I try to get rowIndex of that selected row I get undefined back. var trow = jQuery(#activator + input).parent().parent(); alert(trow.attr(class)); // the class of my row alert(trow.rowIndex); // returns undefined.

Oh yeah! Good point, Rob. I always forget these DOM properties.

Assuming row means the number of tr, and your tables looks like: table trtddata/td/tr trtddata/td/tr trtddata/td/tr trtddata/td/tr trtddata/td/tr /table you can do something like: var count = $(table tr).length; http://docs.jquery.com/Core/length On Feb 8, 8:23 am, pantagruel rasmussen.br...@gmail.com wrote: Hi, I am selecting the row of a table.

Oops, I misread. You wanted the count before the one you selected. Please disregard my response!

[jQuery] Re: selector to return the number of rows in a table before the row I just selected
I did a search but I could only find a selector that selected after something: http://docs.jquery.com/Selectors/siblings#prevsiblings can help. Maybe you can get the total rows count, subtract from the count from prev ~ siblings (and probably subtract 1 also). I hope that helps somewhat.

[jQuery] Re: selector to return the number of rows in a table before the row I just selected
you should be looking at http://docs.jquery.com/Traversing
var currentRow = $('table tr').eq(7);
var howManyBefore = currentRow.prevAll('tr').length;

You could use prevAll()
$('#myrow').prevAll().length;

Oops. Sorry, I didn't see Ricardo's reply before posting. In any case,
there's no need to filter the .prevAll() with 'tr', since no other
element is allowed as a sibling of a tr.
