JS Clone method

Methods of jquery:

Deep copy "can iterate": var Newjson = Jquery.extend (true,{}, JSON);

Shallow copy "Cannot iterate": var Newjson = Jquery.extend ({}, JSON);

var Newjson = $.map (Json,function (n) {return n;});

Methods for cloning arrays:

var Newjson = Json.concat ();

var Newjson = json.splice (0);

There are several ways to copy a new object or array, but if you go directly to the parent "IFRAME case" in the way of the parents of the object, there is a problem "referential relationship", you need to note that you can change the way to pass the data.
