Problem With IE And (ajax) File Upload Via Iframe: Javascript Error Access Denied/zugriff Verweigert
Feb 14, 2007i want to do (multiple) file upload(s) and display a progress bar.
with firefox and safari it is no problem at all. only IE makes some
problems.
my script is based on ajax-uploader, which can be found at
www.srmiles.com/freestuff/ajax_file_uploader/ . you can do multiple
file uploads. each upload will have it's own "form"-tag, so that each
file is uploaded for its own. could be a good solution if there are
"big" uploads.
so here is what i do:
i have a html-page in which several forms with file-input fields are
generated. when i now hit the "one" submit button at the bottom of the
page a javascript function upload() starts it will iterate through all
forms (id='frmUpload_xx'), will get the filename, start a ajax request
for the progress-bar function and do a form.submit().
if the first form/file is uploaded, a settimeout('upload()', 1000); is
called and the next form will be processed. all form's have an
target="uploaddiv", where uploaddiv is a invisible iframe. so the
output of the upload script is put in this div. output should only be
a "OK" at the end. no usefull output no info no nothing.
firefox and safari are working as expected, only IE stops after the
first file is uploaded. i get an javascript error saying "zugriff
verweigert/access denied" on object line x... this is the place where
i call "form.submit()".
this is the upload-function:
function upload() {
if (uploads.length>0) {
form = document.getElementById('frmUpload_'+uploads[0]);
if (form["filename"].value == ""){
alert("Please Choose a file to upload.");
} else {
filename = form["filename"].value;
if (filename.lastIndexOf("")>0) {
filename = filename.substring(filename.lastIndexOf("")
+1,filename.length);
} else if (filename.lastIndexOf("/")>0) {
filename = filename.substring(filename.lastIndexOf("/")
+1,filename.length);
}
makeRequest("upload_progress.php?sid="+sid
+"&filename="+filename,progress);
form.submit();
}
}
}
the strange thing is, that filename is filled correct, that means the
object "form" is found and exisits. the first iteration is working,
only the second ends with an error.
think it have something to do with redirecting the output of the
upload-script in an iframe. after that IE can't access form - at least
IE is not allowed to submit the form as i can access a form field
(filename).
i worked on that the last two days and haven't found a solution...

JQuery :: Access The Content Of An Iframe?
Jun 1, 2009I am trying to access the content of an iframe. I have search google and read a couple of other post, but my problem is a little bit more complicated. I can't use the ...contents().find("whatever") function though the result is of content type text/plain. In other words: There is not HTML is the result. The result cannot be tampered with either. Because contents, html and text are not really helping me I thought to use a counter. Whenever the length would be more than 1 I would show the result. But that doesn't seem to work either.

View 3 Replies View RelatedAccess A Server File Using A File Name Contained In A Variable
Jul 9, 2009Im writing client-side javascript and I want to do a server side include. There are many server files but only one will be included. These files contain peoples names and phone numbers. This info is packaged as a line of javascript but I can change that packaging if necessary.
The file name to include is being passed as a url parameter: [url]
I know how to parse the url string and stuff the ID number into a javascript variable.
I set <ICODE> foo = "/people/12345.html" </ICODE> and tried <ICODE><!--#include virtual="${foo}" --> </ICODE>
but this did not work.
Is there a way to do this with javascript given that the name of the file I wish to include is contained in a variable? If not, what is the usual way of getting the data in the server file into my client-side javascript?

Access Iframe DOM
Apr 17, 2007Is it possible to read the DOM of an iframe if the iframe's src is
from another domain?
I realise I can't manipulate the DOM from another domain for security
reasons, but can I access the DOM and just read object's values?
This is what I've tried so far without any success:
document.getElementsByTagName("iframe").contentWindow;
document.getElementsByTagName("iframe").innerHTML;
document.getElementsByTagName("iframe").childNodes[0].innerHTML;
document.getElementsByTagName("iframe").childNodes[0].nodeValue;
document.getElementsByTagName("iframe").documentElement;
document.getElementsByTagName("iframe").contentDocument.
document.getElementById("testIframe").innerHTML;
document.getElementById("testIframe").childNodes[0].innerHTML;
document.getElementById("testIframe").childNodes[0].nodeValue;

Access Elements Of An Iframe?

the script adds some html code and random images selected from second server inside an iframe tag in the div tag.I need to examine this added html and image properties in my page using javascript.A search on internet did not help, it says elements inside iframe coming from different domain can not be accessedIs there any workaround or hack available to access iframe contents from page javascript?
IFrame, GetSelection(), And Unauthorized Access
Apr 21, 2007I'm trying to figure out a way to have JavaScript use getSelection()
with text located in an iFrame. I've been able to make it work, but only
when the iFrame displays a page located on the parent page's domain.
When the iFrame displays pages on other domains, I get an error --
something about unauthorized access. I'm guessing the error stems from
concerns about scripting attacks.
Possible To Access Attribute Values In IFrame?
Jan 19, 2010I need to copy input (checkbox) values from a form inside my iframe to the form in my parent frame using javascript and I'm not sure how to modify my current code to accomplish this! I'm using cold fusion to display the values from a database inside the iframe. Once all the values are loaded into the iframe, I need to be able to select as many as necessary and then submit the form from the parent frame which then runs a report that utilizes those values, but I can't do that because my code is written so that the values load in the iframe form and the action to run the report that requires those values is executed from the form in my parent frame. Here are the code snipits:
Main "Parent" Frame Code
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<cfparam name="WordFlag" default="0">
<html xmlns="http://www.w3.org/1999/xhtml">
[Code]....
I'm thinking that loading the values into some sort of hidden comma delimited string structure in the parent frame would do the trick, if I'm on the right track, how would I go about doing that?

IFrame Resize To Content Height - Access Parent Document?
Sep 14, 2010I have a webpage with an IFrame in it. The content for the IFrame could change per page and with it size. I don't want scrollbar's inside the IFrame but rather for the whole page.

The links within the Iframe load the new content but I have to access the parent document to be able to resize the IFrame height. How I can resize the iframe from within javascript in the IFrame.
