IFRAME CloneNode Does Not Clone Its Contents?
Jul 27, 2006
I trying to figure out why CloneNode on an Iframe does not correctly clone the IFRAME with its contents and is there a workaround I can use to get pass this?. Basically what I am doing is dynamically building a table with Iframes inside it. The problem is I just want to build one Iframe because the contents of it can be very complex. After my Iframe is built I just want to clone the iframe as many times as I need later. I cannot use an HTML file and point the src of the Iframe to it. I have to put into the Iframe a very dynamic HTML document I get back form an Ajax call. This is truly the key of the problem. Since my pages can be complicated it can take around 2000ms to render. I don’t want to make each Iframe render every time when I already have the document ready to display. I just want to clone it very fast. I can not use the ‘scr’ of the iframe.
Here is a very simple example of my problem. Look near the end of the code to see the problem. Try this code and you can see the IFRAME does not Clone its contents. Is there any way around this problem? Please note that I also cannot use innerHTML to populate the cloned Iframe with my master Iframe’s contents. Because if I do this the page still takes 2000ms to render. I just want this thing to clone as it is. Code:

Is there a way to resize an iframe dynamically so that you never get the scroll bar and essentially hide that there is an iframe? Better integration really.Basically I want to iframe a forum into my site so that the design down the sides and top which my friend does using iweb are not messed with.We have a central area which can be longer or shorter depending on the forum.

I'm trying to pull the source code of the site that my iframe displays. I basically want to get the source code and then display it on the page. I have something like this:
I'm using jquery btw
$("#iframe").ready( function(){
var iBody = $("iframe").contents().find("body");
$("#test").html(iBody.html());

I have a some information opened in an IFRAME.
What I want is to copy this information. How is this done?
What I have (and doesn't work) is:
print "<script>
function copyit(theField) {
var tempval=eval('document.'+theField)
therange=tempval.createTextRange()
therange.execCommand('Copy')
}
</script>
</head>
<body onLoad="copyit('it.TEST');">
<form name='it'>
<IFRAME SRC='$url' NAME='TEST' FRAMEBORDER=1></IFRAME>
<BR><BR>
<textarea name='TEST2' cols=40 rows=10>APPEL</textarea>
</form>
</body>
<html>";
Now, the IFRAME does show something, so it's not empty.
The javascript-error I get reads:
Error: 'undefined' is null or not an object
Code: 0

I'm using IFRAME to connect back to my ASP.NET page in order to fetch the FreeBox HTML Editor html contents and scripts (i do this apprach because the html editor is fairly heafty to send to the user when most dont use it on our site instead deferring to a user request before actually sending down the code via AJAX or in this case an IFRAME).

I've inherited a page which has the following:
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
[Code].....
And I have the CGI take a guess at the size of the content when it generates it. Then I have a call to resizeIframe() with the guessed height in it. This seems to work, but I'm not confident that the guess at the new height is correct. So the other question is: how can I get the correct size of the content of the iframe so I can pass it to the parent function?

I have an intranet page which has an iframe which links to a number of
different possible .NET pages.
In one of the embedded .NET pages (and soon to be others) we want to be
able to capture keystrokes in order to link to other apps. we do this
by setting document.onkeydown to a function which handles the various
possibilities.
The problem I have is that when the intranet page loads with my .NET
page in its iframe, focus is not given to the .NET page, and so in
order for the page to capture keystrokes you have to click on the
contents of the iframe, which is both clunky and (it seems to me)
unnecessary.
How do I automatically give focus to the contents of the iframe when it
loads up? I've tried putting the following script at the bottom of the
intranet page itself, but this doesn't seem to work:

Is there anyway to access an iframe's contents via a selector? Something like this:
$("iframe::contents .my-foo")
I'm constantly accessing an iframe's contents for a project I'm currently working on and $("iframe").contents().find(".my-foo") is becoming a bit tedious to type out.
If this feature doesn't exist in jquery out of the box, is there a plugin that provides this functionality? If not how could I write such a plugin?

I am trying to manipulate the contents of an iframe. I have always had success with this in the past but I am stumped this time. The following code works in FF3x but not in IE8.The first alert comes in correctly while the second returns "null".
var objIframe = $('<iframe></iframe>').attr('src', '/includes/blank.jsp').attr('id', areaIfrId).addClass('areaIfr').attr('frameborder', '0').width(objW).height(objH).appendTo(areaParent).attr('allowTransparency', true).css({
'background': 'transparent',
'padding': '0',

I'm currently trying to get the contents of an iframe's body without any mangling of content by the browser.I could do it by including the content in a textarea, however i want to avoid that.using .innerHTML results in special characters such as "<" ">" and "&" being converted to "<", ">", and "&"respectively.To test, build an html file containing:
{
"id": 5,
"testtext":"I am > than this & < that",

I want to add some classes to various bits on one of Worldpay's lovely payment iframes so I can make it look something like the site it's sat on.
This is the original principle I was using, which works when on a page with the same domain.
Code JavaScript:
$('#worldpay').load(function(){
$(this.contentDocument).find('body').html('Test: This frame was modified with js')
});

I can read the contents of an iframe:
HTML Code:
var iframe = document.getElementById("message");
var iframeContents = iframe.contentDocument.body.innerHTML;
var txtarea = document.getElementById('message2');
txtarea.value = iframeContents;
This will read the contents of an iframe, and write it to a textarea.
iframe is editable, and content is entered by the user. Still, this works.
But, below code is not working. Trying to put some content to an iframe, with the same innerHTML method above. It returns no errors or warnings. Even last alert() displays "<div>lorem ipsum</div>", but iframe is empty, it displays nothing..
HTML Code:
var textContent = "lorem ipsum";
var iframe2 = document.getElementById('message');
iframe2.contentDocument.body.innerHTML = '<div>'+textContent+'</div>'
alert(iframe.contentDocument.body.innerHTML);

In Mozilla (Firefox 1.0.7) I can cloneNode a file input element that
has a selected file value and appendChild it to another form without a
problem.
IE 6 loses the selected file value. Is this a bug with IE that it
loses the value, or with FF that it keeps it?
I'd really like to be able to maintain the selected file value in IE.
Does anyone have any advice or experience with cloneNode that can
provide some insight?
I have not tried this on any browsers other than IE 6 and FF 1.0.7.

I am finding that when I use the cloneNode method to copy an HTML
element that contains a <script> tag, the contents of the <script> tag,
(ie. the javascript) are removed.
If I do this:
var form1 = document.getElementById(sID).firstChild.cloneNode( true);
alert(form1.outerHTML);
I can see the empty <script> tags. I am wondering if there is a
reasonable workaround for this, because I need the script tag with its
javascript content.

I'm playing around with some AJAX-ish stuff and
encountered some problem in the JS side of the universe. Maybe someone
here can suggest an alternative that works.
I have developed a simple ASP.NET application with a web page that
should display a list of users. This list page is designed to start
with an empty table (with columns defined), and, onload, send an
XmlHttp request to a server component (a.k.a. ListServer). This
ListServer is currently simulating a long-running operation. So, it
sleeps for 3 seconds, and then grabs a list of 4 users from an xml
file. It applies an xsl transformation and returns the result.
The xslt is designed to take the xml data and convert it to a
<ListChunkroot element containing a <trfor each user in the XML
data. Each row contains 4 columns (Id, Login, Password, Name). The
javascript in the list page grabs the responseXML from the XmlHttp
object and should, for each <trin it, create a copy of the row
coming from the server and adding it to the list on the client.
I actually got all that to work quite fine. The js snipplet dealing
with copying the row coming from the server and adding it to the table
on the client is: Code:

The problems I am having are with trying to get IE to successfully clone a referenced node from one frame and inport it (with all form values etc) to another frame.
Moz works fine with
oFilters = document.getElementById('saveElement');
oFilters.appendChild(parent.frames[frameref].document.getElementById('e_'+elemref).cloneNode(1));
I have tried iterating the specified node and using createElement to create a copy in the desired place, which works fine with simple input type text or hidden. The first snag comes when trying the same with textareas. The cloned form doesn't submit the values :(
Any ideas? Code:

I am working on a sortable table (full code in attachment). I solved all the intermediate steps till the end when, to my surprise, appenChild() method inserts some previous cloneNodes in looped rows in a peculiar mode, by leaving the end tags </tr> at the end of the table. So far:
1.- build the cloneNodes of the rows as an array, and each index as a paralel array:
//some needed variables on later
t=document.getElementById('tab');
nr=t.rows;
nc=t.rows[0].cells;
//array of rows and rows indexes
var oRows = new Array()
var iRows = new Array()
for(var i=1;i<nr.length;i++){
oRows[i]=t.rows[i].cloneNode(true);
iRows[i]=t.rows[i].rowIndex;
//so far so good, alert shows me what i needed
alert(oRows[i].innerHTML)
}
2. - build an array with the content of the correspondent cells on column and sort this array. The array is double and keep the genuine row's index for later use as each second element. Code:

If a created element:
var newEl = document.createElement("input")
newEl.type = "button"
newEl.value = "I'm a button"
newEl.onclick = function(){..blah..}
is then cloned (http://www.mozilla.org/docs/dom/domref/dom_el_ref35.html#1028396) and inserted into several places in a page:
for(var i=0;i<object.childNodes.length;i++) {
var thisKid = object.childNodes[i]
if(thisKid.tagName=="DIV")
thisKid.insertBefore(newEl.cloneNode(false|true),thisKid.childNodes[0])
}
Will the onclick be cloned as well? I'm havening trouble getting it to fire and am unsure as to what I'm doing wrong.

I'm developing an AJAX toolkit in which I needed a way to write a subset of a markup language to modify the running copy of the document. When implementing part of the append parser I came against a problem. What I'm basically doing is reading the append XML tag, looking where it says It has to add code and then clone the nodes inside that tag and attempt to insert them in the document. The problem comes when I'm trying to append, it seems like all my cloned nodes lose all it's style properties, for example several <li> items would come one next to the other instead of one below the other with the round bullet separation, or an image won't load the actual image. Code:
