Generate A Visible Content From An Invisible Iframe?
Feb 7, 2009
How can I generate a visible content from an invisible iframe?I'm working on a project which involves scanning of content posted through HTTP.For example, a file uploaded to some web-mail client (i.e. Hotmail) as an attachment. If the file is suspected to be a virus, the user should informed and asked whether he wishes to post the file anyway. This scan is made before the file is sent to the server.The message should come from the browser (like JS alert box) but should contain some arbitrary HTML code, not supported by alert box.
Normally, when a file is uploaded, it is done in some hidden iframe. When the upload finishes, the server replies with JavaScript code which when run, notifies the user the upload is done.To inform the user he is uploading a Virus, I'm altering the server's reply to the HTTP post. The altered reply is a JavaScript code which generates some custom dialog box.
The problem is, the page is returned to some invisible iframe, which means the generated dialog box is also invisible. Simple JavaScript alert box works fine as it comes from the browser, and not as part of a webpage. how I can generate a visible dialog boxes, from the hidden iframe?

I understand how to make a div (table) invisible and then visible on a timer.. What I want to do is add a counter to my code and make the table flash 3 times and then stop with the table visible. all my code does right now is make the table flash on and off every 1 second. This is what I have right now:
<script language="javascript" type="text/javascript">
function magic() {
var d = document.getElementById('MagicTable');
if (d.style.display == "none")
d.style.display = "block";
[Code]...

While my PHP is compiling, I have a loading bar. As soon as the body of my page loads, I make the bar invisible and the page contents visible by calling a javascript function with onload event.
Code:
<body onLoad="loadImages()">
When I put the javascript load function in the head between script tags as below it works.
Code:
<head>
<script type="text/javascript">
function loadImages() {
document.getElementById("showme").style.visibility = "visible";
document.getElementById("hidepage").style.visibility="hidden";
}
</script>
</head>
However, when I place the function in an external javascript file, it does not work, which is weird because all my other javascript functions in the external file work.

I have a form, its a very big form. About halfway down is a series of checkboxes (8 or so). Each one toggles whether the item I'm editing belongs to one of the categories or not. Each checkbox is linked to a subform that is invisible. (by subform I mean one or more form elements).
When a checkbox is clicked I want the subform to appear, and when it is unclicked I want it to disappear. Now the tricky part is, that when the page loads, it draws information from the database, and some of these checkboxes will already be clicked, so those forms need to be visible right from the start.
I'm just having far too many problems, can anyone point me towards some information that might help? Reply if I wasnt clear enough and you need clarification.

My problem is I had a drop down menu for a horizonal menu bar but the drop down items are about 4 items long . It works fine for first menu item, but the second one is positioned beneath the first one because it can't fit it's menu on the same line as the previous one.
I have set the submenus to hidden meaning they are there which is why they are taking up the space the other item needs to use when it's menu item is rolled over.
Is there a way to set items so they are invisible but not taking up room when invisible?

I have 3 types of columns and they are identified by their class (in the TD and TH)... they are1. Always - cells that always appear - includes a primary key2. Main - cells that are necessary to be shown, but can be toggled3. Advanced - cells that are superfluous but helpful for the viewer.I want the user to be able to toggle Main and Advanced as visible/invisible. I tried the below code, which works, but, but since there's so much data it will lock up the browser and even invokes this ff error: "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete. Script: jquery-1.3.2.min.js:19"My questions are basically, can this be done without freezing up the browser? (e.g. can I group columns together and hide each column, since I believe it's the sheer amount of cells that I am hiding?)Here is my code:here's my javascript (on top of jquery's inclusion)
Code:
<script type="text/javascript">
$(document).ready(function() {

I'm trying to debug a tabbed menu implementation, where I have a variety of pages that are made visible based on tab clicks. This works well, until I have a page that is laid out with nested divs. Any content beyond the child of the selected page (page_about shows 'Put an image here' but not 'This is where...') remains invisible. I've tried a number of options in the slideDown statement, but failed thus far.

I'm using JQuery to write content into an otherwise empty iframe like so:
Code:
$('#ifrmID').contents.find('html').html(htmlContent);
The content is coming from an Ajax request. The content gets used more than once on the page for other purposes which is why I don't simply change the iframe src--I have to do an ajax request regardless so I'm trying to avoid multiple calls.
After I load the content, I need modify the height of the iframe so it fits snuggly around the content.
Calculating the height isn't a problem with the exception that it's not always correct and I think it's because the calculation is happening before images have downloaded.
I don't seem to be able to rely on a `load` or `ready` event to delay the calculation. The load event is the only one that tiggers on a change of iframe content, but it doesn't see the new content.
Code:
$('iframe').each(function () {
$(this).load(function () {
alert($(this).contents().find('html').html());
});
});
This will output '<html><body></body></html>' even though I have successfully inserted different content.
Any suggestions on what I'm doing wrong, or if it's possible to do what I want reliably?
Note that a general JS solution will be appreciated as much as a JQuery one.

I have the following code that don't work like i want it.
Code:
function hideDisplaySingleSuite(textstring) {
var myclass1 = new RegExp('\b'+textstring+'\b');
//Populate the array with all the page tags[code]....
For example.It show objects if I remove the if statement that checks if the class is visible.for example this shows a class and works.
Code:
function hideDisplaySingleSuite(textstring) {
var myclass1 = new RegExp('\b'+textstring+'\b');
//Populate the array with all the page tags[code]....
So my question is why don't this work on a class, it works on an "id"?
Code:
if (allPageTags[i].style.display ==''){
allPageTags[i].style.display = 'none';
}[code]....
I want to show the class if its not visible or hide it if it is visible.How can this be done?

I am a little confused about this and whether this is an appropriate approach. I have put this together so far. What it does is display a different html page into the IFrame if the person clicks the link. However, this is not what I want to do. What I want to do, is if Windows XP is detected to display load1.html into the Iframe and if Windows Vista is detected to display load2.html into the iframe.
<style type="text/css">
<!--
iframe#ifrm {

I have a situation where I'd like to read/parse the content
of a file I've read into an <IFRAME>. I've looked through
various FAQs and searched forums, and the closest I get to
accessing the file content is
myIframe.contentWindow.document.body.innerHTML
where myIframe is the node from getElementById(). But while
I can see the content of the file on my web page, I get an
empty string from the above reference. How do I get to the
file?

I am trying to get at the content of an iframe but it seems that the content is loading after the alert is fired:
index.php:
<!doctype html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title>iFrame test</title>
<script src="[URL]"></script>
<script type="text/javascript">
$(function() {
$('<iframe src="[URL]" id="the_iframe" name="upload_iframe" />').load(function(){
var txt = $('#the_iframe').contents().find('#inside_iframe').text();
alert(txt);
}).appendTo('body');
});
</script></head><body>
</body></html>
In test.php I just have:
<div id="inside_frame">this is some text</div>
I don't get any errors in the console and the alert() just returns an empty string. I've also tried just placing the iframe directly in the html and that gets the same result too.

I have:
var moreinfo ="";
moreinfo+= "here some content";
$("#divMoreInfo").html(moreinfo);
And this inserts "here some content" in a div called divMoreInfo.
Now divMoreInfo is placed inside an iframe while the rest of the programming has to be in the parent page... How do I insert moreinfo's contents in the iframe's div?

I've been able to get the iFrame to resize to the content - see this link - it's pretty simple. My only problem, is if the user clicks a link so that another page is displayed, the iFrame doesn't resize. It will only resize when the parent page is reloaded. So, not sure what to do about that.
(I do work with someone who writes Javascript and PHP, so they would know how to implement it if I found a solution).
