i wonder how google manages to open external links in a new window/tab without defining target="_blank".
For example in google plus, all external links open in a new window.
I think its some Javascript voodoo but the .js code is obfuscated so i cant really look into.
edit: oh and followup question: why?
Using a framework makes this easy. Just have JavaScript look for links marked rel="external", or another identifier that shows them to be an external link, and dynamically add target="blank". Here's an example using Prototype:
$$('a[rel="external"]').each(function(a) {
a.setAttribute('target', '_blank');
};
It's not beyond reasoning for them to add the target attribute by javascript before allowing the anchor link event to return true.
It's Javascript. You can say:
window.open('http://example.org', '_blank').focus();
But please, don't. Opening links in new windows is almost always the wrong thing to do. Seriously, good uses of this are vanishingly few. If users want a link opened in a new window, they are quite capable of doing that themselves.
Jakob Nielsen was telling people this twelve years ago. Others have taken up the cudgels. The W3C removed the target attribute from HTML 4 because it was such a bad idea. I honestly don't understand how this usage persists. Don't you find it incredibly annoying when a website does this to you? Why would you want to write a website which does this to someone else?
Which brings me to your followup question. Why did Google decide to do this? I have no answer to that, and i am completely and utterly baffled how one of the very biggest, brightest, web companies could make such an elementary mistake. But then, a lot of the Google Plus interface has very poor usability (as in, mostly worse than Facebook poor); i suspect there is an interesting story behind it. Was the project under-resourced, and thus built cheaply on top of a rapid development framework such as GWT? Was it built as a spare time project by a lone wolf with a blind spot for web architecture? Was it driven by strategy wonks who didn't care about getting the technology right? Mystery.

How could I access a website and turn components of the website into strings. For example taking information from Facebook posts. I have done a little searching but can't find any good tutorials or anything useful.
Try looking at this tutorial. It should get you more familiar on the subject and start you off on the right track.
As it states at the beginning of the tutorial...
How to Parse HTML on iOS
Let’s say you want to find some information inside a web page and
display it in a custom way in your app. This technique is called
“scraping.” Let’s also assume you’ve thought through alternatives to
scraping web pages from inside your app, and are pretty sure that’s
what you want to do. Well then you get to the question – how can you
programmatically dig through the HTML and find the part you’re looking
for, in the most robust way possible? Believe it or not, regular
expressions won’t cut it! Well, in this tutorial you’ll find out how!
You’ll get hands-on experience with parsing HTML into an Objective-C
data model that your apps can use.

I'm developing for the Xbox with XNA currently, but when I click on several links to the official Microsoft site, e.g. tutorials and files, then I get redirected to this page:
http://forums.create.msdn.com/forums/t/19992.aspx
For example by clicking this link:
http://create.msdn.com/en-US/education/catalog/sample/skinned_model
Anyone having the same problems with the official Microsoft site currently?
Yes. Microsoft are aware of this issue - although I'm not privy to any information about when/if they will fix it.
Basically, as part of the move to Windows Phone 8, they've separated out the Xbox and Phone development stuff.
If you come across old links like that, you can usually repair them by hand by changing the domain like so:
forums.create.msdn.com becomes xboxforums.create.msdn.com (change the subdomain)
And
create.msdn.com becomes xbox.create.msdn.com (add a subdomain)
Yes.
It'd be like this for a month now. It seems to suggest they are trying to downplay XNA for Windows 8 development which is saddening! You could always use Google's caching service to view the pages if you are finding them from Google... I don't think this will work for downloads though!
i have a website, its to exchange links, files... to say it quickly it's my 'version' of twitter+megaupload,
Well, users add links all the time and so on, but i would like user be able to syinch his bookmarks from the browser to the ones he has at his profile of mywebsite,
Where should i look into?
Basically i need to be able to:
- Acces bookmarks file (1)
- being able to send the urls to my service ( 2 )
- maybe adding the login feature (in the future)
I was google'ing about this for ages few weeks a go and i kind of give up, because i'm ok with PHP and JS, but with this plugin languages i'm very lost. So i decided posting here, wich always brings positive answers
(1) - > I don't even know where to start
(2) -> i was thinking to have a website.com/auto_import_no_confirm.php?url=[URL] and put it in a for each.
how many different languages and extension files do i have to work with? I really need any kind of tip with point (1)
feel like?
-edit-
Just found This -> https://developer.mozilla.org/En/Code_snippets/Bookmarks
wich really looks like i need, but where do i place this code?
thanks!
Might not be a bad question, but there are too many subtopics raised to answer that. (And there is too much tagspam as well. Break up your question into PHP- and Javascript-specific tasks, when you have devised the general application scheme.)
But to get started, download similar Firefox extensions (.xpi) and unzip them to inspect the general structure. You'll find examplary code for bookmark handling and invoking remote APIs pretty quickly. And basically you only need Javascript for the extension itself. (It sounds like your extension does not need much UI.)
And there are many tutorials on designing Firefox addons: http://roachfiend.com/archives/2004/12/08/how-to-create-firefox-extensions/ or http://www.google.com/search?q=firefox+develop+an+xpi
The good news first, you won't need much more than javascript if you just want to access bookmarks and send them to a server, neither on firefox nor on chrome.
But still you'll have to make yourself familiar with the apis of the browsers and learn how to develop extensions.
However, both Mozilla and Google provide all necessary information on their developer sites.
For Chrome, this is a good place to start, you'll find the api for bookmark access here.
The Corresponding site for Firefox can be found here, with information on bookmark access here.
Now that idselector has been upgraded to RPXNow and you can't "just use" the selector code, what is a good replacement?
I want to implement OpenId on a new website that I am using, but the users are going to be just dumb when it comes to logging in unless I provide an easy way for them to.
As a reference, I will be using .Net Open Id for the background in an ASP.Net MVC web application.
EDIT
After some cheap thought, what about using the rpxlib?
Jarrett Vance made a "version" of open-selector that is much more developer/designer friendly.
This selector is different because it does not hide the markup details in javascript. Therefore, you can easily add new providers or rearrange the existing ones without digging into the javascript. The login form will still work for normal OpenID logins if javascript is disabled
The best of all, is that it comes with documentation, demo, and lots of images both cropped and as raw .pdn files (paint.net)
Jarrett Vance's openid-selector can be found here
(source: jvance.com)
PS: I would suggest reading this article before implementing RPX.
Another one to consider is http://code.google.com/p/openid-realselector/ (which is a rewrite/update of http://code.google.com/p/openid-selector/)
I have done an implementation with RPXLib and RPXNow, and it is really pretty straight forward.
I wanted to minimize the amount of work done in the OpenId format, and the RxpLib definately helped with that one.
RpxNow also has a nice feature of telling me new users, number of logins per day, etc...
I've made Open-selector, which you just add to your site and switches the regular OpenID box into a provider list and a username text input.
The code is pretty simple (in case you need extra customization) and there is an inline mode so it doesn't alter your original layout.
I was using that one, but then I found a few people using a different one which made me investigate, and I found this OpenID selector. There aren't any instructions per se other than the demo.html, but it shouldn't be too hard to figure out. Just include the css and js, then call the javascript function with the right parameter.
Edit about rpx: I chose to stay away from rpx because I didn't want to have a 'central point of failure,' and a site that isn't my own that users would authenticate to/through. It seems kind of counter-intuitive being that I'm using openid, but if you consider that the openid provider that the user is using as part of the user, then it kind of makes sense.
I am unlucky to be in charge of maintaining some old Yahoo! Store built using their RTML-based platform.
Recently I've noticed that HTML code generated by some RTML functions is sprinkled all over with "padding images" (or whatever is the conventional name for those 1x1 pixel images used to enforce layout). I have nothing against using such images, but... all those images are supplied with an ALT attribute like this:
<img href="http://.../image1x1.gif" alt="pad">
With all due respect to the original authors of RTML, but they must have been smoking something when they came up with this "accessibility enhancement"... :-(
Anyway, here are my questions:
Does anybody know a list of all RTML functions that generate HTML with all these "pad" images?
Is there any way to get rid of all those alt="pad" attributes without rewriting a lot of RTML code?
NB: This may sound a little cynical, but improved accessibility is not the main goal here. The main goal is to stop exposing those moronic alt="pad" attributes to Google and other smart search engines. So client-side scripting is not going to help, as far as I know.
Thank you!
P.S. Probably, most of you are really lucky and never heard of RTML. Because if somebody would establish a prize for software products based on
commercial success
------------------
usability
ratio, this RTML-based "platform" would probably win the first place.
P.P.S. Apparently someone from Yahoo! finally listened, because I can no longer find those silly "pad" tags in the RTML generated for our store. Nevertheless, one of the ideas offered in response to my original question does provide a very practical solution - not just to the original problem but to any similar problem with RTML platform. See the winning answer - it's really good.
The only way I see is to have your own website front-end that will filter whatever you want from the RTML site....
for example, your rtml site is at http://rtmlusglysite.yahoo.com/store/XYZ01134 , you could host a simple PHP front-end at http:://www.example.com that would be acting like a "filtering" HTTP web proxy, so http://rtmlusglysite.yahoo.com/store/XYZ01134/item1234.rtml would be accessed by http://www.example.com/item1234.html
It's not an ideal solution, but it should work, and you could do some more fancy stuff.
Nice try from the other posters, but there is a very simple RTML command that will do it. . .
TEXT PAT-SUBST s GRAB
MULTI
HEAD
BODY
TEXT #var-with-alt-tag-equals-pad-in-it
frompat "alt=\"pad\""
topat ""
The above RTML will find all instances of alt="pad" and replace it with nothing.
Well you're right on RTML being relatively untraveled :)
Do you have a way to add your own attributes to these images tags? If so, would it be possible to override the alt attribute? If you specify alt="", I would think that would override Yahoo's... Otherwise consider putting a useful alt tag in there for the blind and dialup types.
It's the first time I'm hearing about this platform, but here is an idea: if you can add javascript to the pages, you could write a function that will run after the page has loaded and remove all the alt="pad" attributes from the page.
Unfortunately this solutions works only with browsers that know about scripting, so lynx or some other text based browsers might not support it.
I have shared a link official RTML guide from yahoo. Hope it will help. Thanks!
