I want to be able to determine wheter a jQuery object was created from
an existing DOM element, or if it is new/created "on-the-fly".
Given the following examples:
Example 1:
HTML:
<html>
<body>
<div id='title'><h1>Title</h1></div>
</body>
</html>
JavaScript:
var elem = $('#title');
Example 2:
var elem = $('<div id='title'><h1>Title</h1></div>');
How can I tell if elem came from an existing DOM? I was assuming that
I could just check the parent() - expecting the result to be null for
Example 2. However, this is what I get:
$('#title')parent()[0].nodeName; // returns BODY
$('<div id='title'><h1>Title</h1></div>').parent()[0].nodeName; //
returns DIV
Any ideas?
