I use the js onKeyup event to trigger server side db searches in a
hidden iframe page and generate a list of selectable items in the
parent page. The minimum characters to initiate a search is 3. I'm
trying to minimize the number of unnecessary db calls as much as I
can. It seems like if I type in 6 characters real fast then there's
only one db call after the last keyup, which is good .. but I'm not
sure. Maybe the previous calls for the 3rd,4th,5th do occur but
quickly cancelled/overridden by the next call. I'm looking for a way,
say, not to call the search after the 3rd keyup if the 4th,5th,.. are
entered real quick. Any ideas? Thanks.
