javascript - Get data from inside an iFrame on the same page -

I am trying to do something like this:

  var data = $ (' # Uptar ') content () .; . $ ("# FileRes") HTML (data);   
 Where #user is an iframe and #fileer is a div, then i need all the data from the iframe (in HTML format) in the diff iframe is dynamically loaded.  
  Edit  
 Additional code looks like this:  
  $ ("# addmore"). Click (function () {$ ("# progForm"). Submit (); $ ('# upTar'). Load (function () {$ ("# title, #obj, #theory, #code, # Output, #conc "") .val (""); var data = $ ('# above'). Content (). ("Body") .html (); alert (data); $ ("# fileRes" ) .HTML (info);});});   
 The goal of submitting a form is an iframe (#upTar) on the same page. Once loaded, I I want to transfer its data to the Div.

 try  HTML ()   
  Content  brings back the top-level HTMLElement node itself, then you ("#up") also capture HDM from this node. And you probably do not want all the HTML including the head section, first you need to find body tags.
