Throwing exception if elem is undefined

Line 539 in 7191c17

if ((elem && elem.nodeName) || elem.jquery) {

Current code-
$[pluginName] = function(elem, data, options) {
if ((elem && elem.nodeName) || elem.jquery) {

Looks like above line of code is missing undefined check in OR condition.

Proposed solution-
if ((elem && elem.nodeName) || (elem &&elem.jquery) ) {
