I create a selector, then filter() that selector and put

a length check on the end to see if anything matches, eg

var jSelector = $("foo");

if (jSelector.filter("bar").length > 0) ...

Which works fine.

I was hoping I could avoid jQuery filtering the entire

selector, by sticking a ":first" on the end of the filter

(ie "hey, stop filtering on the first one you find"), eg

if (jSelector.filter("bar:first").length > 0) ...

What happened is that, even though the original selector

found no matches (length ==0), the added filter suddenly returned a match (length == 1).

var jNewRows =

$("#table tr:has(td[id$=status] :contains('New'))");

--- console.log(jNewRows) sez []

var a =

jNewRows.filter("td[id$=volume] input[value]");

--- console.log(a) sez []

var b =

jNewRows.filter("td[id$=volume] input[value]:first");

--- console.log(b) sez [input#...] (single entry)
