get the id inside a HTMLTableRowElement

Hi Experts!

I am using jQuery to get as an array the tr id's for a given filter

var comment = $('tr[id$=comment]').get();
for (var k in comment ) {
	console.log(comment [k]);
}

Select allOpen in new window

After executing this code I get in the console the actual <tr> element array like this

<tr style="display: none;" id="[b]name1_comment[/b]">

Select allOpen in new window

How one can get the tr id from this?  In jQuery one uses

$(this).attr('id')

Select allOpen in new window

in an each, but I would like to know if there is a pure JS way to do it.

Thank you!
