Verify if jQuery found an element
If you want to check if jQuery found an element, always check for its length
var element = $(selector);
if (element.length) {
//do something

It may be a good idea to assign the jQuery object to a var, especially if your selector works on a large DOM.
Concider:
var $testDivs = $("#test").find("div");
if ($testDivs.length) {
//use $testDivs without searching the DOM again
