How to first try to find and then check if an element exists?

Question

I am running the following but it is giving all the lists:

if($($wikiDOM.find('.infobox .location').length )) {
  $("#results").append("<li>" + $wikiDOM.find('.infobox .location').text() + "</li>");
}

United States
undefined
United States
undefined
undefined
undefined
undefined

I'd only need the ones with a location not undefined.

@CommercialSuicide I did see few answers, I am not sure if the issue is that in my case I first need to `.find` then check if it exists and I am doing it wrong, as you can see on my code I am using `length` as they suggest — rob.m, Jul 23 '17 at 17:12

if($($wikiDOM.find('.infobox .location').length )) {

should be

if($wikiDOM.find('.infobox .location').length) {

(no need to push that length-value into a jquery-object)
