you could do:
for(var j=0; j<10; j++) {
var the_row = 'tr_' + j; // create the id field value
var rowDisplay = eval("document.getElementById(the_row).style.display";
alert ("display is " + rowDisplay);
}
I tried it on a webpage that uses mooTools and one that uses jQuery, it worked
on both.
javascript:(function(){target='*target_id*';alert(document.getElementById(target).innerHTML);})();
I'm pretty sure it will work in javascript with no added libraries.
