getAttribute("id") does not return values on dynamically created table rows

ha mo, Dave Clark, windi wee,

Windi,
     The first question is whether an ID value was assigned to the 
dynamically-created table row in the first place.  Then, rather than 
try to use getAttribute(), just check the object directly:
var tbl = document.getElementById("tableId");
var rows = tbl.rows;
var x, len = rows.length;
for (x=0; x<len; ++x)
{
    if(rows[x].id
    && !/^\s*$/.test(rows[x].id))
        alert("Row " + (x+1) + " has '" + rows[x].id + "' id value.");
    else
        alert("Row " + (x+1) + " has no id value.");
}
Take care,
Dave Clark
