X-UA-Compatible ignored when page launched by ShowModalDialog - javascript

I am wondering if someone can help me with the "X-UA-Compatible" tag with regards to launching a modal dialog.
I have the following page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<meta http-equiv="X-UA-Compatible" content="IE=9" />
<title></title>
</head>
<body onload="load()">
<form id="form1" runat="server">
<iframe name="fr1" frameborder="0" id="fr1" width="675px" height="550px"></iframe>
.
.
.
var src = http://someurl.web;
document.all.fr1.src = src;
If I browse directly to this page (not to the http://someurl.web, but the page with the IFrame on it that points at http://someurl.web), the "X-UA-Compatible" stuff will work correctly, however, if I launch my page like below:
window.showModalDialog(urlToPage, "", "dialogHeight: 550px; dialogWidth: 800px; center: Yes;")
The "X-UA-Compatible" stuff is ignored. Why is this? What do I need to do in order to get that tag to be recognized when the page it is on launched via showModalDialog? This is happening when using IE9 on an Intranet site with "Display Intranet site in Compatibility View" Management will not allows to uncheck this, hence the use of the "X-UA-Compatible" tag.

As I understand it, in IE9 (and newer), if a page is launched in an iframe, the document mode will match that of the parent document, regardless of any X-UA-Compatible meta element or server header, unless the parent is using standards mode and the iframe specifies quirks mode. I'm not aware of a workaround.

window.open in https iframe does not open as pop up

I have a very simple button that opens a login popup window. The button is placed inside an iframe. The button resides on a different web site than the main page. When running this on my dev/stage site, all using http, all works as expected, the login pops up with no menubar or extra stuff. As soon as I copy to production and try and load the iframe content over https (main page still http) then Microsoft Edge ignores my settings to not show menubar, etc. and opens the button in a normal browser window, in another session. This works fine in IE, Chrome, etc. I cannot find anything published that says Edge is doing something different for cross browser and https iframed inside an http page.
Here is the resulting html for the iframe and it's contents:
<iframe name="logInOut_btn_iframe" width="200" height="32" class="btn-login-iFrame" id="logInOut_btn_iframe" src="https://www.website.org/logInOut_btn_iFramed.html" frameborder="0" marginwidth="0" marginheight="0" scrolling="no" allowtransparency="yes">

JavaScript object properties are "sometimes" undefined

I am very confused.
I created the following script which is located at http://tapmeister.com/test/dom.html. For some unknown reason, tinymce.editors.ta1 and tinymce.editors[0] show up as undefined, and attempting to use a method under them results in an error. But when I inspect tinymce or tinymce.editors using FireBug, I see them in the DOM.
So, I create a jsfiddle http://jsfiddle.net/JWyWM/ to show the people on stackoverflow. But when I test it out, tinymce.editors.ta1 and tinymce.editors[0] are no longer undefined, and the methods work without error.
What is going on??? Maybe something to do with public/protected/private properties? How do I access methods such as tinymce.editors.ta1.hide()? Thank you!!!

TinyMCE doesn't do all of the setup work immediately when you call init. It provides a callback, setup, to tell you when the work is done.
So if you provide a setup callback, you can interact with the editor instance then.
Here's an example (I've also moved your scripts to the end, which is best practice regardless):
Live Example | Live Source
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1" />
<title>Testing</title>
</head>
<body>
<form>
<textarea id="ta1"></textarea>
<textarea id="ta2"></textarea>
</form>
<script src="http://tinymce.cachefly.net/4.0/tinymce.min.js"></script>
<script type="text/javascript">
tinymce.init({
selector: "#ta1, #ta2",
setup: function(e) {
console.log("Editor " + e.id + " is ready");
}
});
</script>
</body>
</html>
Now, if you want to actually access the editor instance, bizarrely TinyMCE doesn't add it to tinymce.editors until after calling the setup function. But if you throw in a brief yield, you're all set. Here's the above with a changed setup function:
Live Copy | Live Source
setup: function(e) {
// Bizarrely, TinyMCE calls `setup` *before* adding
// the relevant editor to `tinymce.editors`,
// so we have to yield briefly
console.log("Editor " + e.id + " is ready");
if (e.id === "ta2") {
console.log("It's ta2, I'll hide it in a moment.");
setTimeout(function() {
tinymce.editors[e.id].hide();
}, 0);
}
}
So why did it work on jsFiddle? Well, jsFiddle has a truly brain dead surprising default setting, which is to put all of your script in a window#load callback function. window#load happens very late in the load process, after all external resources have been loaded. (You can see that in the jsFiddle UI, it's the second drop-down list on the left.) So apparently TinyMCE was completely ready at that point, where it isn't earlier in the cycle.
Side note: 99.9% of the time, there is absolutely no point in supplying a tag name with an id selector, e.g. textarea#ta1. id values are unique, so you don't have to qualify them unless you explicitly want to avoid matching an element that may sometimes have one tag name, or other times have another, which is a pretty unusual use case.
There's a large chance that your script is running before tinyMCE has actually loaded. It might be the case that it loads faster from your test site so that is why it works.
Use as a quick check.

google chrome iframe body onLoad not working?

EDIT: It does work (sorry). Something in this script is causing it to stop in google chrome:
function checkLocation() {
var loc = top.location.href;
var suffix = "subpage.html";
if (loc.indexOf(suffix, loc.length - suffix.length) !== -1) {
top.location.href = "index.html";
}
}
Original post:
I have IE 9, FF 3.6.3, Chrome (18.0.1025.151) and Safari 5.1.5 all installed.
This works in all of the browsers except google chrome.
I have a HTML layout which contains a named iframe. The iframe src changes to display the different pages. On one of the pages I have a script which is loaded onLoad in the body tag. This script doesn't load when the page is loaded in the iframe in google chrome only - it works fine in other browsers. Also, if I load the page directly into google chrome (not via an iframe) it works just fine.
How do I fix this?
Here is an example code:
index.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html> <head> <title> Example Page </title> </head>
<body> View subpage<BR/>
<iframe name="targetFrame"> </iframe>
</body>
</html>
subpage.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html> <head> <title> Subpage </title>
<script type="text/javascript" src="subpage.js"> </script>
</head>
<body onLoad="initialise()"> Hello </body>
</html>
subpage.js
function initialise() {
alert("Script loaded.");
}
Thanks for looking.
Turns out its just a security exception
Unsafe JavaScript attempt to access frame

Once its online it should be fine.

How to reload an IFrame every x seconds?

Was wondering how I can reload an iframe every x seconds, perferably not using javascript.
Thanks.
With a Refresh: x HTTP header or with an HTML element in the document loaded into the iframe:
<meta http-equiv="refresh" content="x" />
This element should be placed inside of the document's <head/> element.
If you do not have control over the document loaded into the frame or the server that it is served from, you have two options:
JavaScript.
Write another HTML page with the above <meta/> element and include an iframe in that page targeting the other page. So you will have an iframe inside an iframe: outer document -> iframe(inner document with meta-refresh) -> iframe(original iframe target)
EDIT: Regarding option #2, here's a decent generic iframe in PHP that gives some flexibility in terms of refresh time and style. Just call it with something like:
http://www.mydomain.com/genericIframe.php?url=http://my.domain.com/mypage.htm&refreshTime=60&style=putYourStyleAttribHere
Here's the PHP/HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Generic Iframe</title>
<meta http-equiv="refresh" content="<?php print $_REQUEST['refreshTime']; ?>" />
</head>
<body>
<iframe src="<?php print $_REQUEST['url']; ?>" style="<?php print $_REQUEST['style']; ?>"></iframe>
</body>
</html>

How to get scripts to fire that are embedded in content retrieved via the jquery load() method?

I have found several other questions here on S.O. (and the web in general) that ask roughly this same question, but the answers always seem to suggest other ways of structuring code that avoid the need for addressing this underlying issue.
For example, many people suggest (and a good suggestion, I agree) to put your code in the jquery load method's callback, on the calling page and not the called page. However I have unique scripts that may appear in certain resources, so I would not want to do that for every load and nor do I necessarily know what these scripts will be.
Here is a test setup to demonstrate what I'm trying to do. The short summary is that when I load partial.htm from main.htm, its script does not fire.
main.htm:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>main file</title>
</head>
<body>
<ul id="links">
<li>some page1</li>
<li>some page 2</li>
<li>some other partial page</li>
</ul>
<div id="panel" style="display:none; padding:20px; background-color:#CCC;">
LOADED CONTENT WILL GO HERE
</div>
<script type="text/javascript" src="/path/to/jquery-1.3.2.min.js"> </script>
<script type="text/javascript">
$(function(){
$('#links a').click(function() {
var $panel = $('#panel');
$panel.show();
$panel.html('Please wait...');
var href = $(this).attr('href');
$('#panel').load(href + ' #content');
return false;
});
});
</script>
</body>
</html>
OK, very simple functionality on this page. Imagine there are many more links, and some of them may require scripting while others do not.
Here is partial.htm:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>partial file</title>
</head>
<body>
<div id="content">
<p>Hey, I am the partial file!</p>
<script type="text/javascript">
alert('I am some JS in the partial file! But sadly I do not execute...');
</script>
</div>
<div>
I am some other content on the page that won't be included by jquery.load()...
</div>
</body>
</html>
Notice that my script in partial.htm does not fire. So, my question remains: how to get this to fire, excluding any answers that tell me to put this in the .load() method's callback. (This would be because I may not have the fore-knowledge of which scripts these partial pages may contain or require!)
Thank you!
Update #1:
I suppose an acceptable answer is simply "you can't." However, I'd like to know if this is definitively the case. I haven't been able to find anything that officially states this yet.
Also, when I use firebug to inspect the panel region afterwards, there is no script element present at all. It is as if it is being parsed out by load.
Update #2:
I've narrowed this down to be a problem only when using the selector as part of the href. Loading the entire "somepage.html" will execute the script, but loading "somepage.html #someregion" does not.
$panel.load('somepage.html'); // my script fires!
$panel.load('somepage.html #someregion'); // script does not fire
I'm going to try and hunt down why this may be the case in the jquery source...
Well it seems that this is by design. Apparently to make IE happy, the rest of us suffer. Here's the relevant code in the jquery source:
// See if a selector was specified
self.html( selector ?
// Create a dummy div to hold the results
jQuery("<div/>")
// inject the contents of the document in, removing the scripts
// to avoid any 'Permission Denied' errors in IE
.append(res.responseText.replace(/<script(.|\s)*?\/script>/g, ""))
// Locate the specified elements
.find(selector) :
// If not, just inject the full result
res.responseText );
I'm wondering if, instead of just stripping out the scripts, I could modify the jquery source to include them in some other way that makes IE happy? I still have yet to find anything else on the web discussing this matter, I'm sure I'm not the only person stumped by this?
I have run across issues before with IE not running injected <script>s that didn't contain the defer attribute. This discussion thread has some good information about the topic: innerHTML and SCRIPT tag
