How do I print rotated content (divs) in IE8? The DXImageTranform filter options do not appear to be printable.
http://msdn.microsoft.com/en-us/library/ms533014(v=vs.85)
Just to put this into context. I'm writing a pure dom-based canvas library called simpleCanvas. I am desperately trying to offer rotation of text, rectangles and images in IE8 without using a VML fallback, because it's ugly and slow, and error prone. A VML fallback is on my todo list as I concede that it's the only way I know how to do this in IE8 without additional tools. I'm hoping that there is some trick that I'm missing that doesn't come with a third party or server side requirement. If you have found it, a bounty is coming your way.
This is a massive stretch but is the best idea I could come up with:
Explorer Canvas - https://code.google.com/p/explorercanvas/ - Implements the canvas in IE8 by abusing VML.
HTML2Canvas - http://html2canvas.hertzen.com/ - Can render your document onto a canvas, which can then be rotated.
Failing that, I suspect your only option is going to be to generate a rotated document server-side and give that to the client for printing.
Edit: One other last ditch would be to handle the printing via Silverlight, embedding the page in a browsercontrol inside silverlight (yuck), rotating that and printing the result via SL.
Really grasping at straws here though for anything client side in a legacy browser.
According to Printing webpage with rotated text in Internet Explorer 9 you need to use -ms-transform too. Be sure to read the EDIT too as there is something buggy.
Would https://developers.google.com/chrome/chrome-frame/ be acceptable? I'm guessing not if its a LOB application, but it'd give you the features you need without taking the user out of IE8 in the strictest sense. Just another avenue to explore.
https://code.google.com/p/jqueryrotate/ - This will rotate images, it uses VML to do it in IE8. The caveat is that any text you wanted to rotate would have to be as an image.
I've never used it and it would be some work but have you tried svgweb? Basically it uses SVG if the browser supports it and Flash if it doesn't. Because it's a flash object you can print it like an image once rendered.
Here's a few more demos of it: svgweb Demos
So I'm nearly finished with the website I had to make for my school's prom. Now, I just checked it in Internet Explorer and, well, it's hopeless. Elements aren't where they're supposed to be, most of the JavaScript/jQuery doesn't work at all. I am clueless where to start to make my site compatible with Internet Explorer. Whats the best way to make your site compatible with IE?
The main cross browser step is DOCTYPE Declaration. It is an instruction to the web browser about what version of HTML the page is written in.
It's going to be murder to fix what's already broken... you really needed to start off on the right foot, as it is you may need to re-write large chunks of your site in order to get things working again.
Going back? Well the easiest thing is going to be to start a fresh layout (using the following pointers) and then move your site into the new framework. Depending on the scale of your site this is no small task. Your alternative is one-by-one code debugging, with maybe firebug light
Going forward, how do you build a site that works more evenly across the board?
1 Use a reset CSS boilerplate
I like the html5 one at http://html5reset.org/. These apply layers of CSS to get each browser looking the same to start with (your CSS then gives it the style you want). Note they DON'T address the variety of ways browsers calculate things - borders being part of the width or not (firefox/ie difference)
2 Use a JS library
Or write your own, but be aware of all the differences between the browsers don't just code for the one you're using. Build some JS tests for the library that you can run in any browser to make sure that the library performs as expected, then deal with any site oddities after that. There's too many JS libraries to make a recommend but Prototype.js and jQuery are a popular two.
well it's known that there are differences between browsers. The way browsers render CSS code is also different. You should check parts and see how or if it works as you want. :) There is no one-to-all solution. The experience will let you know what works and what not. But to start you could isolate what is not working in IE (javascript code) and then see what alternatives you have. As for the appearance, there is the option of having separate CSS files especially for IE. However, often there is a technique(a different way to implement the same appearance) that lets you create the appearance you want without multiple versions of code.
There is a page that uses PHP to fetch search results from Google Search API and then it puts the results on the page some funny way in a circle. The code may look crappy but seems that it works more or less fine in Firefox. When you enter a search query and click submit button or Next/Previous links, it fills the wheel with results. The problem is its work in IE. It works there very slowly and then it doesn't clear the wheel before filling in new data, but puts it over that. My friend asked me to help him with this code. Please give me a piece of advice how I can fix it. Thanks so much!
Raphael runs very slowly under IE documented here.
As I understand it, VML itself in IE is fast enough, but the Raphael layer has some inefficiency.
I see you're using Raphael.js, which renders vector in VML/SVG (depending on browser). IE8 has degraded support for VML, unfortunately, and I hear it's also quite a bit slower than IE7. BTW, in IE7 it's kinda funny looking.
In terms of Raphael, it may be something as simple as resetting some context, I'm not sure. I've looked at Raphael before, but never used it.
We're having the following weird (well...) behavior in all versions of Internet Explorer browsers when using javascript slideshows.
You can see what I mean here http://www.tospirto.net/index.php?ID=photo_gallery&Rec_ID=481
In the last 3 images there are white lines and artifacts created by the browser.
This is true as I said for all versions of Internet Explorer.
Have you seen this before??
Do you ave any idea what is causing this???
Thank you
I can see the artifacts - strange! This is a known issue in IE's JPEG rendering algorithm. If you enlarge the pictures in Photoshop, you will see that the artifacts are restricted within encoding blocks. (Pardon me, but I assume you know roughly how JPEG is encoded.)
Try encoding the images with a different quality, or even in a different format (like PNG, even though that would give you larger files). You can find other thoughs on how to solve this here:
http://forum.jquery.com/topic/ie-dead-pixels-when-fading-images
It's a bug in the alpha filter, which is how transparent fades are implemented in IE (before version 9, which finally supports proper CSS opacity). When used directly on an image, any pixel with the RGB values 2,5,10 (aka #02050A) is treated as transparent.
This is how 1-bit transparency from eg. GIF is implemented in the alpha filter. Evidently Microsoft think this particular colour is so seldom used no-one will notice. Oops.
Avoid the bug by putting the alpha filter (or fade script that uses it) on a container <div> instead of on the image itself.
Alternatively, you can use an AlphaImageLoader filter (same hack as for transparent PNG loading on IE6) to load the image, or just get rid of the alpha filter when you're not in the middle of a fade (you still see the bug during fade but at least it doesn't appear at 100%).
OK I found what was wrong after some searching.
The effect is called swiss army image artifacts and you can find more about it here: http://www.dynamicdrive.com/forums/showthread.php?t=34462
Another great bug from explorers :)
The solution is on the referenced article which is to remove absolute blacks using the levels tool on the photoshop for example. Did a batch change using actions in photoshop for all pictures and works like a charm.

While developing for multiple sets of browsers, what issues have you faced while development due to differences in browser implementation?
To start with I am listing some of those which i faced:
A text node in Firefox allows only 4K data. So an XML Ajax response gets split up into multiple text child nodes instead of only one node. Its fine in Internet Explorer. For Firefox, to get the full data you either need to use node.normalize before you call node.firstChild or use node.textContent, both of which are Mozilla specific methods
Internet Explorer does not replace or HTML char code 160, you need to replace its Unicode equivalent \u00a0
In Firefox a dynamically created input field inside a form (created using document.createElement) does not pass its value on form submit.
document.getElementById in Internet Explorer will return an element even if the element name matches. Mozilla only returns element if id matches.
In Internet Explorer if a select box has a value not represented by any of the options, it will display blank, Firefox displays the first option.
The only one that really gets to me:
IE6 is still used by ~18% of the web -- that's nearly 1 in 5 -- and addressing its issues is time consuming, hackish, and frustrating. ;) The issues are really too numerous to list here.
If you're interested in the issues themselves, QuirksMode.org is an amazing resource I used every day before making the leap to client-side libraries. Also check out John Resig's The DOM is a Mess presentation at yahoo, which gives a lot of theory about how to deal with cross-browser topics efficiently.
However, if you're interested in simply having them solved, your question is an excellent example of why many consider using client-side libraries like jQuery, YahooUI, MooTools, Dojo, etc. With a thriving community, talented people and corporate backing projects like those allow you to focus on your app rather than these issues.
Here are some jQuery examples that avoid much of the cross-browser frustration and can really make all of this.. fun.
Cross-browser mouse click binding
$('#select anything + you[want=using] ~ css:selectors').click(
function(){
alert('hi');
}
);
Cross-browser HTML Injection
$('#anElementWithThisId').html('<span>anything you want</span>');
Cross-browser Ajax (all request objects are still made available to you)
$('p.message').load('/folder/file.html');
And what really blows me away, load a data subset with selectors (see manual for details)
$('p.message').load('/folder/file.html body p:first-child');
Now, how all this really starts to get fun: chaining methods together
$('ul.menu a').click( // bind click event to all matched objects
function(evt){ // stnd event object is the first parameter
evt.preventDefault(); // method is cross-browser thx to jquery
$(this) // this = the clicked 'a' tag, like raw js
.addClass('selected') // add a 'selected' css class to it
.closest('ul.menu') // climb the dom tree back up to the ul
.find('a.selected') // find any existing selected dom children
.not(this) // filter out this element from matches
.removeClass('selected'); // remove 'selected' css class
}
)
Reminds me of Joel's Can Your Programming Language Do This? article.
Taking all this to a theoretical level, true advancement doesn't come from what you can do with conscious thought and effort, but rather what you can do automatically (without thought or effort). Joel has a segment on this in Smart And Gets Things Done regarding interviewing questions and smart developers, completely changed my approach to programming.
Similar to a pianist who can just 'play' the music because she knows all the keys, your advancement comes not from doing more things that require thought but rather more things that require no thought. The goal then becomes making all the basics easy.. natural.. subconscious.. so we can all geek out on our higher level goals.
Client side libraries, in a way, help us do just that. ;)
Most of the problems I have are with IE, specifically IE6. Problems I personally deal with that have left a memorable impression (in no particular order):
Having to use frameworks to do basic things because each browser implements the DOM a little differently. This is especially heinous with IE and AJAX, which necessitates multiple if-blocks just to get the call started. In an ideal world I'd be able to work in JavaScript without the framework to do basic things.
onChange on selects in IE are implemented wrong, and fire before the select loses focus (which is incorrect). This means you can never use onChange with selects due to IE, since keyboard-only users will be crippled by this implementation issue.
You mentioned it in your post, but it's a huge pain when IE grabs an element by name when using getElementById().
When in an RTL locale (Arabic, Hebrew, etc.), Firefox implements "text-align: right;" incorrectly. If the container overflows for some reason, the text aligns to the right side of the viewable container, rather than the right side of the container itself (even if it makes part of it invisible).
Different browsers have differing levels of pickiness with regards to how you end arrays and objects. For example, Firefox is more than okay with an array looking like this: [ item0, item1, ]". However, this same code will make Opera barf because it hates the trailing comma. IE will make the array a three-item array, with the third item undefined! This is bad code for sure, but there's been dynamically generated javascript I've worked on that was a huge pain to rewrite - would've been nice if this just worked.
Everything having to do with IE's hasLayout. So much awful pain has revolved around this attribute, especially when I didn't know it existed. So many problems fixed by using hacks to add hasLayout. So many more problems created as a result of the hacks.
Floats in IE rarely work the way you hope they do. They also tend to be annoying in other browsers, but they at least conform to a particular behavior. ;)
IE adding extra white space between list items has caused me no end of pain, since YUI uses lists to make their menus. (To fully grasp the issue, you have to view that link in IE and another browser side by side.)
I have lots of issues getting text not to wrap in containers in IE. Other browsers listen to "white-space: nowrap" a lot better. This has been a problem with a UI I worked on that has a resizable sidebar; in IE, the sidebar items will start to wrap if you resize it too much.
The lack of many CSS selector types in IE6 means you have to class-up your DOM more than necessary. For example, the lack of +, :hover, :first-child.
Different browsers treat empty text nodes differently. Specifically, when traversing the DOM with Opera, I have to worry about empty text nodes when browsing a node's children. This isn't a problem if you're looking for a particular item, but it is if you're writing code that expects a particular input and the way the browser views that input differs.
In IE6, when you dynamically generate an iframe via javascript, the iframe sometimes doesn't fill its container automatically (even with width and height set to max). I still don't know how to solve this issue, and have been thinking of posting a question about it.
In IE, you can't set overflow CSS on the <tbody> element. This means that scrollable tables (with a concrete <thead> and <tfoot>) are impossible to make in a simple manner.
I will probably add more to this list later, since (to me) the worst part of web development are cross-browser issues. Also, I doubt I'll ever edit out the "I will probably add more to this list later", since these problems are endless. :)
IE6? Meh. You guys have got it easy! You've never had to make CSS layout work in Netscape 4 (without crashing the entire browser)? You've never had to write for appliance browsers that don't support tables? You've never had to write for IE Mobile?
there is no support for JavaScript-assigned event handlers; you can only write an event handler through setting “onclick="somestring"” in innerHTML;
most basic DOM Level 1 properties (eg. nodeName, nodeType, nodeValue, firstChild, lastChild, nextSibling, previousSibling, data, value, HTMLElement.getElementsByTagName, all HTMLTableElement members, most CSSStyleDeclaration members) simply do not exist;
most CSS layout properties do not work; many simply CSS properties like ‘width’ don't work on some elements such as form fields;
setting many other CSS properties on elements like tables and form fields causes an instant browser hang, which, since Windows Mobile has no built-in task manager, means you have to soft-reset the device;
oh, and putting anything but text inside a <button> is insta-crash too;
huge chunks of basic JavaScript methods and “DOM Level 0” methods going back as far as Netscape 2 (!) are missing.
And this is the most up-to-date release of Microsoft's flagship Windows Mobile browser in 2009.
Sure, it supports XMLHttpRequest, but writing AJAX code on a browser whose CSS and script support is less than IE3 (!) is bizarrely schizophrenic, like you're working with a weird amalgam of 21st-century and 19th-century technologies.
I wouldn't recommend it.
Been doing this too long to have many problems, but it still drives me nuts that I have to hack around IE's non-support for CSS things like display:table, :last-child, and :hover outside of anchors.
All the IE stuff is still insane, but it's just background insanity now :)
Biggest Cross-Browser Issue? - Internet Explorer!
<start_grumpy>
IE is solely responsible for "holding back the web" - us developers can't create amazing sites using HTML5, or SVG, or XFORMS, or CANVAS... not because of Firefox,Safari or Chrome, but because 2/3s of the Internet is still stuck on IE. Not to mention that ~20% of the web is still stuck on IE6! IE8 is the first version of IE to at least try to be standards compatible (2001's standards that is), which means it will be at least 2018 before we can finally start dropping all support for IE7.
</start_grumpy>
Otherwise name a DOM method that IE fully supports... the fact that this is a hard question to answer is my biggest CrossBrowser issue.
getElementById() - badly broken
getElementsByName() - buggy
getElementsByTagName() - buggy
getAttribute() - buggy
setAttribute() - majorly broken
createElement() - buggy
appendChild() - buggy
even things IE invented are messed up...
innerHTML (getting) - returns the worst markup possible
innerHTML (setting) - doesn't work on the elements you'd want to dump a bunch of data into (e.g. Tables and Selects)
While developing a system tests framework for a web app we had to simulate various events such as clicks. I remember that we couldn't find any normal way to do it in IE and FF and had to implement it in two different ways with a lot of voodoo around.
I don't remember the specifics, but I remember that it was really annoying.
This, basically.
Modern javascript frameworks (jQuery, prototype, etc) have done wonders for getting code working in lots of browsers at once.
The biggest problem I have now is the fact that any sort of rich UI behaviour runs amazingly slowly. IE7 is bad. IE6 is worse. IE8 is buggy, half finished, and really no better than IE7.
The worst thing is that I don't think we'll ever be free of IE6. It was so ubiquitous, and so damn quirky. Loads of 'enterprise' (and by that I mean big web apps made by one big company for another big company) applications used highly specific IE6 javascript that doesn't even work in IE7, never mind anything else.
Companies can't afford to completely replace these apps - we're trying to sell them new ones and that means IE6 support is mandatory. The way it is right now, with credit-crunched companies cutting costs, I reckon we'll still be supporting IE6 in 2015 :-(
In internet explorer (note: older versions of IE, not necessarily versions 9/10+), if you create form elements using document.createElement, the field won't be submitted with the form. The only workaround is to use
element.innerHTML = "<input type='text' value="+val+" name="+name+">";
In IE, you can not hide select option elements, only the select element itself. This makes it difficult to dynamically change the contents of select options using Javascript.
This problem also exists in Safari and Chrome.
There are many other issues with IE, but this one has caused me the most frustration recently.
IE's restrictions on using DOM manipulations on tables forced me to take a completely different approach to something. Very frustrating at the start, but the positive out of it was that the second approach was ultimately better, so I suppose I should be grateful to IE. ;)
For Firefox, to get the full data you either need to use node.normalize before you call node.firstChild or use node.textContent, both of which are Mozilla specific methods
Actually all of those are W3C DOM methods supported by the vast majority of browsers. I think you'll find they also work in IE.
My biggest cross-browser issue is that there are people out there still using IE.
Second biggest is that even in standards-following browsers, doing some things in CSS is still impossible; for instance tbody {overflow:auto} does nothing useful in anything but Gecko, and even there it has bugs.
Firefox and IE ahve different table setups in the DOM, in one, all siblings of a cell are the other cells, whilst the other has elements between the cells. I can't remember which way around it is, but it gave me a real headache in one application.
My biggest problem are browser makers. Arrogant little *^&%s. I mean, you can't sell a browser to anybody, yet everyone is in their little corner trying to out do each other, only creating division. Oh and Chrome. Chrome still doesn't know what it wants to be, Safari or Firefox. Aside from its one parlor trick, its practically useless. I blame all you guys who kept googling just because you hate monopolies. Guess what, they're the monopoly now. Now we can all enjoy second rate, prematurely launched software.
This mostly stems from a bug* I had in Chrome today, it never dawned on me to query the browser. Both Safari and Chrome were failing so I figured hey, once I fixed the Safari problem Chrome would be fixed automatically, but oh no no. Mr."I run tabs in seperate processes" AKA "Sr. No full screen" just had to hold me in the lizard lock with its mind boggling implementation.
I also detest Firefox. I can't tell whether I have a virus infestation or Firebug running. Now until Adobe decides to release a browser that makes Flash practical for things other than movie clips I'm pretty much going to have something to bitch about for a long time. And we all know that's what life is all about.
Also, I only enjoy programming when I encounter ridiculous bugs that make my brain juices run.
Inconsistencies in the CSS box model when dealing with forms. In particular it's irritating how each browser handles the <select> Box
my only nightmare is IE6 you should always look for hacks but everytime you face a problem with it there is someone who ran into it before you and blogged about it (and we will never get away from it )
I was working on CSS layout written by someone who thought that the size given to an element is size+padding+border like in IE5 and not only the content box as explained in official specification. It was written only a few month ago so he did dirty hacks to make it look well in IE7. It took me several hours with FireBug to track down the source of the problem and by the time I realized it I was really annoyed.
If you open site with "floating" CSS written for IE5 in Firefox the boxes just do not have enough space to fit and fall down the page. If you open it in IE7 it looks nice as IE7 lets the borders overlap so it looks almost correct. For someone as inexperienced as me it was hard to note.
To remove iframe borders in Internet Explorer you have to specify the frameborder attribute as camelCase format, which is non xhtml compliant.
<iframe frameBorder="0"/>
An easy way to help with the pesky IE display issues is to use firebug, Yep enen in IE 6/7/8 Just use Firebug Lite
If you add the following as a bookmark and stick it on your tool bar it will enable firebug lite off any webpage with a single click. (only check this in IE and it works fine.)
javascript:var%20firebug=document.createElement('script');firebug.setAttribute('src','http://getfirebug.com/releases/lite/1.2/firebug-lite-compressed.js');document.body.appendChild(firebug);(function(){if(window.firebug.version){firebug.init();}else{setTimeout(arguments.callee);}})();void(firebug);
