  • Is it practical to have perfect validation score on HTML?

    - by Truth
    I was in a heated discussion the other day, about whether or not it's practical to have a perfect validation score on any HTML document. By practical I mean: Does not take a ridiculous amount of time compared to it's almost-perfect counterpart. Can be made to look good on older browsers and to be usable on very old browsers. Justifies the effort it may take to do so (does it come with some kind of reward on SEO/Usability/Accessibility that cannot be achieved in a simpler way with almost-perfect validation) So basically, is perfect validation score practical on any HTML document?

  • Do I have to learn html and javascript to create web applications?

    - by vainolo
    I am an experienced Java programmer, and I want to create a complex web application requiring dynamic pages, drawings, etc (take SO as an example). Do I have to learn javascript/html in order to create such an application? It is not that I don't want to learn another language (I've done this before), but technology on the javascript environment seems to change so fast that when you finish learning one framework it is already obsolete. I have checked a number of java framework for web development (spring, play), but not deeply. So can these frameworks (or other possible java frameworks that I'm not aware of) be used without learning html/javascript? I also have some python experience. So if I can do the app in python it is also an option.

  • How to wrap Ruby strings in HTML tags

    - by Jason H.
    Hi all: I'm looking for help on two things. 1) I'm looking for a way for Ruby to wrap strings in HTML. I have a program I'm writing that generates a Hash of word frequencies for a text file and I want to take the results and place it into an HTML file rather than print to STDOUT. I'm thinking each string needs to be wrapped in an HTML paragraph tag using readlines() or something, but I can't quite figure it out. Then, once I've wrapped the strings in HTML 2) I want to write to an empty HTML file. Right now my program looks like: filename = File.new(ARGV[0]).read().downcase().scan(/[\w']+/) frequency = Hash.new(0) words.each { |word| frequency[word] +=1 } frequency.sort_by { |x,y| y }.reverse().each{ |w,f| puts "#{f}, #{w}" } So if we ran a text file through this and received: 35, the 27, of 20, to 16, in # . . . I'd want to export to an HTML file that wraps the lines like: <p>35, the</p> <p>27, of</p> <p>20, to</p> <p>16, in</p> # . . . Thanks for any tips in advance!

  • html in do_GET() method of a simple Python webserver

    - by Meeri_Peeri
    I am relatively new to Python but have been doing a lot of different things with it recently and I am liking it a lot. However, I ran into trouble/block with the following code. import http.server import socketserver import glob import random class Server(http.server.SimpleHTTPRequestHandler): def do_GET(self): self.send_response(200, 'OK') self.send_header('Content-type', 'html') self.end_headers() self.wfile.write(bytes("<html> <head><title> Hello World </title> </head> <body>", 'UTF-8')) images = glob.glob('*.jpg') rand = random.randint(0,len(images)-1) imagestring = "<img src = \"" + images[rand] + "\" height = 1028 width = 786 align = \"right\"/> </body> </html>" self.wfile.write(bytes(imagestring, 'UTF-8')) def serve_forever(port): socketserver.TCPServer(('', port), Server).serve_forever() if __name__ == "__main__": Server.serve_forever(8000) What I am trying to do here is grab a random image from multiple images in the directory and add it into the response to a web request. The code works fine but when I access the server via browser, the image is not displayed. The html of the page is as intended though. The permissions on the files are 755. Also I tried to create an index.html file in the do_GET method. That didn't work either. I mean the index.html was generated fine, but the response in the browser this time did not show anything (not even the hello world in the title). Am I missing anything very simple here? I was thinking should I overload the handle_request of the underlying SocketServer.BaseServer as the documentation says you should never override BaseHTTPServer's handle() method and should rather override the corresponding do_* method?

  • Whats happening to my HTML?

    - by user156814
    I am making changes to my website, and I just noticed that things look different. In IE, the content doesnt center, theres a margin on my content, and the font looks bigger in chrome.. I ran it through Yahoo's HTML validator and the error I get is line 1 - Error: character "" not allowed in prolog. I believe that there may be some sort of whitespace being sent before the DOC TYPE, but I cant seem to fix it. The HTML looks fine in my text editor (Notepad++) so I dont know what the problem is. Im using a strict DOC Type. Everything was fine before I made any changes, but I cant pinpoint what caused the change. If it helps, I'm using a Framework (Kohana). My initial thought was that something was being sent to the browser by an echo or something, but I couldnt find any echo statements. I dont know what could be causing this... If you want to see any code or HTML just ask. Thanks. Heres the HTML (only head and doctype) via the page source in Google Chrome There seems to be some foreign characters in the source that I've never seen before, yet dont show up anywhere else (yahoo, or otherwise) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Recent Debates - Clashing Thoughts</title> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <meta http-equiv="Content-Language" content="en-us" /> <meta name="description" content="Clashing Thoughts is a great place to argue!

  • Persisting settings without using Options dialog in Visual Studio

    - by Utkarsh Shigihalli
    Originally posted on: http://geekswithblogs.net/onlyutkarsh/archive/2013/11/02/persisting-settings-without-using-options-dialog-in-visual-studio.aspxIn one of my previous blog post we have seen persisting settings using Visual Studio's options dialog. Visual Studio options has many advantages in automatically persisting user options for you. However, during our latest Team Rooms extension development, we decided to provide our users; ability to use our preferences directly from Team Explorer. The main reason was that we had only one simple option for user and we thought it is cumbersome for user to go to Tools –> Options dialog to change this. Another reason was, we wanted to highlight this setting to user as soon as he is using our extension.   So if you are in such a scenario where you do not want to use VS options window, but still would like to persist the settings, this post will guide you through. Visual Studio SDK provides two ways to persist settings in your extensions. One is using DialogPage as shown in my previous post. Another way is to use by implementing IProfileManager interface which I will explain in this post. Please note that the class implementing IProfileManager should be independent class. This is because, VS instantiates this class during Tools –> Import and Export Settings. IProfileManager provides 2 different sets of methods (total 4 methods) to persist the settings. They are LoadSettingsFromXml and SaveSettingsToXml – Implement these methods to persist settings to disk from VS settings storage. The VS will persist your settings along with other options to disk. LoadSettingsFromStorage and SaveSettingsToStorage – Implement these methods to persist settings to local storage, usually it be registry. VS calls LoadSettingsFromStorage method when it is initializing the package too. We are going to use the 2nd set of methods for this example. First, we are creating a separate class file called UserOptions.cs. Please note that, we also need to implement IComponent, which can be done by inheriting Component along with IProfileManager. [ComVisible(true)] [Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")] public class UserOptions : Component, IProfileManager { private const string SUBKEY_NAME = "TForVS2013"; private const string TRAY_NOTIFICATIONS_STRING = "TrayNotifications"; ... } Define the property so that it can be used to set and get from other classes. public bool TrayNotifications { get; set; } Implement the members of IProfileManager. public void LoadSettingsFromStorage() { RegistryKey reg = null; try { using (reg = Package.UserRegistryRoot.OpenSubKey(SUBKEY_NAME)) { if (reg != null) { // Key already exists, so just update this setting. TrayNotifications = Convert.ToBoolean(reg.GetValue(TRAY_NOTIFICATIONS_STRING, true)); } } } catch (TeamRoomException exception) { TrayNotifications = true; ExceptionReporting.Report(exception); } finally { if (reg != null) { reg.Close(); } } } public void LoadSettingsFromXml(IVsSettingsReader reader) { reader.ReadSettingBoolean(TRAY_NOTIFICATIONS_STRING, out _isTrayNotificationsEnabled); TrayNotifications = (_isTrayNotificationsEnabled == 1); } public void ResetSettings() { } public void SaveSettingsToStorage() { RegistryKey reg = null; try { using (reg = Package.UserRegistryRoot.OpenSubKey(SUBKEY_NAME, true)) { if (reg != null) { // Key already exists, so just update this setting. reg.SetValue(TRAY_NOTIFICATIONS_STRING, TrayNotifications); } else { reg = Package.UserRegistryRoot.CreateSubKey(SUBKEY_NAME); reg.SetValue(TRAY_NOTIFICATIONS_STRING, TrayNotifications); } } } catch (TeamRoomException exception) { ExceptionReporting.Report(exception); } finally { if (reg != null) { reg.Close(); } } } public void SaveSettingsToXml(IVsSettingsWriter writer) { writer.WriteSettingBoolean(TRAY_NOTIFICATIONS_STRING, TrayNotifications ? 1 : 0); } Let me elaborate on the method implementation. The Package class provides UserRegistryRoot (which is HKCU\Microsoft\VisualStudio\12.0 for VS2013) property which can be used to create and read the registry keys. So basically, in the methods above, I am checking if the registry key exists already and if not, I simply create it. Also, in case there is an exception I return the default values. If the key already exists, I update the value. Also, note that you need to make sure that you close the key while exiting from the method. Very simple right? Accessing and settings is simple too. We just need to use the exposed property. UserOptions.TrayNotifications = true; UserOptions.SaveSettingsToStorage(); Reading settings is as simple as reading a property. UserOptions.LoadSettingsFromStorage(); var trayNotifications = UserOptions.TrayNotifications; Lastly, the most important step. We need to tell Visual Studio shell that our package exposes options using the UserOptions class. For this we need to decorate our package class with ProvideProfile attribute as below. [ProvideProfile(typeof(UserOptions), "TForVS2013", "TeamRooms", 110, 110, false, DescriptionResourceID = 401)] public sealed class TeamRooms : Microsoft.VisualStudio.Shell.Package { ... } That's it. If everything is alright, once you run the package you will also see your options appearing in "Import Export settings" window, which allows you to export your options.

  • Move options between multiple dropdown lists

    - by Martha
    We currently have a form with the standard multi-select functionality of "here are the available options, here are the selected options, here are some buttons to move stuff back and forth." However, the client now wants the ability to not just select certain items, but to also categorize them. For example, given a list of books, they want to not just select the ones they own, but also the ones they've read, the ones they would like to read, and the ones they've heard about. (All examples fictional.) Thankfully, a selected item can only be in one category at a time. I can find many examples of moving items between listboxes, but not a single one for moving items between multiple listboxes. To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. An additional problem is that sorting between lists is all well and good in the javascript-enabled world, but I can't really think of a good fallback interface for, say, mobile browsers. Maybe a pseudo-listbox with radio buttons next to each item? The master list of items will in general be very long - over 100 items, certainly, possibly many more. Any given category will most likely contain one or two selected items, but the possibility exists for a category to have dozens of selected items, or zero selected items. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting. This one form for this one client is currently the big exception. Give 'em an inch and they want a mile... Oh, and I have to add: I suck at Javascript, or really at any C-descendant language. Curly braces give me hives. I'd really, really like something I can just copy & paste into my page, maybe tweak some variable names, and never look at it again. A girl can dream, can't she? :)

To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. EDIT: Having now actually sat down to try to code the non-javascripty bits, I need to revise my question, because I realized that multiple select lists won't really work from the "how do I inform the server about all this lovely new information" standpoint. So the html code is now a pseudo-listbox, i.e. an unordered list (ul) displayed in a box with a scrollbar, and each list item (<li>) has a set of five radio buttons (unselected/own/read/like/heard). My task is still roughly the same: how to take this one list and make it easy to categorize the items, in such a way that the user can tell at a glance what is in what category. (The pseudo-listbox has some of the same disadvantages as a multi-select listbox, namely it's hard to tell what's selected if the list is long enough to scroll.) The dream solution would be a drag-and-drop type thing, but at this point even buttons would be OK. Another modification (a good one) is that the client has revised the lists, so the longest is now "only" 62 items long (instead of the many hundreds they had before). The categories will still mostly contain zero, one, or two selected items, possibly a couple more if the user was overzealous. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting.

  • Redirect .html but not .html?with=options

    - by Leonard
    I'm currently using an .htaccess to get round a problem with a CMS, nothing major and an htaccess fix is tidy enough. I'm currently using the format... redirect 301 /pictures.html http://www.domain.com/gallery.html The problem though this causes is that the CMS uses pictures.html?vars=here to select galleries and so the redirect breaks this part of it. Is there any way I can redirect pictures.html but not when it has variables attached?

  • Javascript "inlet" or "offset" function for drop-list options

    I have seen on several sites that drop list values can have offsets... For example this drop-list: Fruits Apple Banana Orange Colors Red White Black The above are all options, but some have "inlets" or "offsets" or whatever you want to call it. How is this done with js? (regular js, not jquery at the moment) Thanks If you need more input let me know.

  • Is there an offline HTML editor for writers?

    - by Jason Christa
    All of our writers and editors use Microsoft Word for document creation and a lot of what they create ends up on the Web. Is there a good offline editor with a flavor similar to Word that they could use to create their documents. Styling of the content should not be a concern, only producing semantic HTML (most documents they create could be done using only header and paragraph tags for instance). They have tried CKEditor and TinyMCE but it is still too foreign for them and it is online so they don't trust it not to lose their work.

  • Modify HTML Content with Squid

    - by user38400
    We have setup our network as per the tutorial here: https://help.ubuntu.com/community/Upside-Down-TernetHowTo. Basically, we have a squid proxy that inverts images for pages that clients request. We're trying to modify the script so that we can edit the contents of the webpage before the webpage is sent to the client. We are not having any luck. I'm wondering if there is something different about .html files that makes this not possible. What is happening is that we do a wget on the URI that is requested, save it locally, modify it and then echo back the new URI. The page that the user gets is the unmodified page and not the one that we just changed.

  • Non-embedded font with different name across operating systems when printing HTML to PDF

    - by sennett
    I create a document using HTML markup. I want to use Palatino, which is called Palatino on Windows and Palatino Linotype on Mac, so I specify my CSS accordingly: font-family: Palatino Linotype, Palatino, serif;. I then print to a PDF using PrimoPDF under Windows. It all looks good when viewed in Windows. But I want this PDF to look the same on a Mac, and the resulting file size (94KB) would suggest that the font (size 460KB) is not getting embedded by Primo, perhaps because it is a native font. How will this look? Will the PDF file format resolve this, or will the format of my PDF be wang when viewed under OSX? Please note that I do not want to embed the font. I used a web-safe font to avoid this need, and it just so happens that the one I picked does not have the same name in OSX as in Windows.

  • Automate opening HTML and printing to PDF

    - by craigpatik
    I need a way to automate the following process in Windows 7: Open an .html file in Internet Explorer Print to PDF Save the PDF with a patterned file name (i.e., original_name_YYYY-MM-DD.pdf) Ideally, I could drag and drop several files or open a whole folder of files at once and a PDF would be created for each one. A command line solution is also acceptable. The files have to be opened in the browser because parts of the page are rendered with JavaScript on page load. In other words, if you simply right-click on the file in Explorer and choose "print", the resulting file is not the same because the JS didn't run. If it helps, Internet Explorer can be set as the default browser, and a PDF printer can be set as the default printer.

  • android webview returns blank page when load dynamic html page

Will that maybe the reason? Then, I added @SuppressLint("SetJavaScriptEnabled") on top of the activity. The warning is gone, but the js code in pages seem still not work.

You can find them here and here.I am creating a small content website (only text,images and a contact form) for a friend of mine.He wanted to create a rollover gallery.The whole concept is that we have some small thumbnails on a page, the user hovers over them and they appear enlarged on a designated container/placeholder on a page. I am trying not to use Javascript scripts when I am using effects on a web page and this is what I will be doing in this post.  Well some people will say that HTML 5 is not supported in all browsers. That is true but most of the modern browsers support most of its recommendations. For people who still use IE6 some hacks must be devised.Well to be totally honest I cannot understand why anyone at this day and time is using IE 6.0.That really is beyond me.Well, the point of having a web browser is to be able to ENJOY the great experience that the WE? offers today.  Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. In order to be absolutely clear this is not (and could not be ) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.For the people who are not convinced yet that they should invest time and resources on becoming experts on HTML 5 I should point out that HTML 5 websites will be ranked higher than others. Search engines will be able to locate better the content of our site and its relevance/importance since it is using semantic tags. Let's move now to the actual hands-on example. In this case (since I am mad Liverpool supporter) I will create a rollover image gallery of Liverpool F.C legends. I create a folder in my desktop. I name it Liverpool Gallery.Then I create two subfolders in it, large-images (I place the large images in there) and thumbs (I place the small images in there).Then I create an empty .html file called LiverpoolLegends.html and an empty .css file called style.css.Please have a look at the HTML Markup that I typed in my fancy editor package below<!doctype html><html lang="en"><head><title>Liverpool Legends Gallery</title><meta charset="utf-8"><link rel="stylesheet" type="text/css" href="style.css"></head><body><header><h1>A page dedicated to Liverpool Legends</h1><h2>Do hover over the images with the mouse to see the full picture</h2></header><ul id="column1"><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/john-barnes.jpg" alt=""><img class="large" src="large-images/john-barnes-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/ian-rush.jpg" alt=""><img class="large" src="large-images/ian-rush-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/graeme-souness.jpg" alt=""><img class="large" src="large-images/graeme-souness-large.jpg" alt=""></a></li></ul><ul id="column2"><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/steven-gerrard.jpg" alt=""><img class="large" src="large-images/steven-gerrard-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/kenny-dalglish.jpg" alt=""><img class="large" src="large-images/kenny-dalglish-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/robbie-fowler.jpg" alt=""><img class="large" src="large-images/robbie-fowler-large.jpg" alt=""></a></li></ul><ul id="column3"><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/alan-hansen.jpg" alt=""><img class="large" src="large-images/alan-hansen-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/michael-owen.jpg" alt=""><img class="large" src="large-images/michael-owen-large.jpg" alt=""></a></li></ul></body></html> It is very easy to follow the markup. Please have a look at the new doctype and the new semantic tag <header>. I have 3 columns and I place my images in there.There is a class called "large".I will use this class in my CSS code to hide the large image when the mouse is not on (hover) an image Make sure you validate your HTML 5 page in the validator found hereHave a look at the CSS code below that makes it all happen.img { border:none;}#column1 { position: absolute; top: 30; left: 100; }li { margin: 15px; list-style-type:none;}#column1 a img.large {  position: absolute; top: 0; left:700px; visibility: hidden;}#column1 a:hover { background: white;}#column1 a:hover img.large { visibility:visible;}#column2 { position: absolute; top: 30; left: 195px; }li { margin: 5px; list-style-type:none;}#column2 a img.large { position: absolute; top: 0; left:510px; margin-left:0; visibility: hidden;}#column2 a:hover { background: white;}#column2 a:hover img.large { visibility:visible;}#column3 { position: absolute; top: 30; left: 400px; width:108px;}li { margin: 5px; list-style-type:none;}#column3 a img.large { width: 260px; height:260px; position: absolute; top: 0; left:315px; margin-left:0; visibility: hidden;}#column3 a:hover { background: white;}#column3 a:hover img.large { visibility:visible;}?n the first line of the CSS code I set the images to have no border.Then I place the first column in the page and then remove the bullets from the list elements.Then I use the large CSS class to create a position for the large image and hide it.Finally when the hover event takes place I make the image visible.I repeat the process for the next two columns. I have tested the page with IE 10 and the latest versions of Opera,Chrome and Firefox.Feel free to style your HTML 5 gallery any way you want through the magic of CSS.I did not bother adding background colors and borders because that was beyond the scope of this post. Hope it helps!!!!

  • Can I use <link> tags in the body of an HTML document?

    - by Edward Touw
    Can I use <link> tags in the body of an HTML page? I tried to find the answer to this question, but found contradictory information. When adding Schema.org microdata markup to an HTML page, I want to add canonical info in a link tag like this: <div itemscope itemtype="http://schema.org/Book"> <span itemprop="name">The Catcher in the Rye</span>— <link itemprop="url" href="http://en.wikipedia.org/wiki/The_Catcher_in_the_Rye" /> by <span itemprop="author">J.D. Salinger</span> </div> I got the example code above from Schema.org. According to them, this is the way to go for people that want to add a canonical reference to an itemprop, but don't want to place a hyperlink on their website. W3 however clearly states that <link> tags should only be placed within the head section, thus making the Schema.org example invalid. If I want to stick to correct markup, which advice should I follow?

  • Interpreting Inkscape SVG path coordinates for HTML map

    - by tovare
    I needed some coordinates for a HTML MAP and tried to use inkskape by opening the image and just draw a path with my polygon coordinates. My document properties are set to 256 x 256 pixels and units: px When opening the svg file i get coordinates which are not immediately apparent. <path style="fill:none;stroke:#000000;stroke-width:1px;stroke-linecap:butt; stroke-linejoin:miter;stroke-opacity:1" d="m 23.864407,126.91525 3.254237, 44.47458 35.79661, 44.47458 71.593216, 19.52542 71.59322, -37.9661 22.77967, -72.67797 L 218.0339, 64 192,49.898305 l -32.54237, 8.677966 -18.44068, -35.79661 1.08474, -17.3559322 -71.593215,0 L 45.559322,34.711864 35. 79661,57.491525 5.4237288, 74.847458 6.5084746,101.9661 23.864407,126.91525 z" id="path2840" /> How can I get coordinates I can use ? The original image The SVG file from inkscape Link to SVG Progress: I tried a tool called InkscapeMap which looks promising and simple, but unfortunately it looks like it didn't work with this particular svn file. Solved! Saving the file as a Plain SVG solved the problem and InkscapeMap worked perfectly. (Btw. saving as an optimized svg caused a parsing error) Update 13.11 Using inkscapeMap 0.6 and Inkscape 0.48 i needed to uncheck relative coordinates in SVG output preferences. Also if you get a C error message, hunt down the polygon with a C in it, and redraw the polygon using the XML editor in inkscape. Update 25.11.2011 I modified the source to improve parsing. http://tovare.com/articles/createhtmlimagemapsusinginkscape/

  • A Semantic Model For Html: TagBuilder and HtmlTags

    - by Ryan Ohs
    In this post I look into the code smell that is HTML literals and show how we can refactor these pesky strings into a friendlier and more maintainable model.   The Problem When I started writing MVC applications, I quickly realized that I built a lot of my HTML inside HtmlHelpers. As I did this, I ended up moving quite a bit of HTML into string literals inside my helper classes. As I wanted to add more attributes (such as classes) to my tags, I needed to keep adding overloads to my helpers. A good example of this end result is the default html helpers that come with the MVC framework. Too many overloads make me crazy! The problem with all these overloads is that they quickly muck up the API and nobody can remember exactly what order the parameters go in. I've seen many presenters (including members of the ASP.NET MVC team!) stumble before realizing that their view wasn't compiling because they needed one more null parameter in the call to Html.ActionLink(). What if instead of writing Html.ActionLink("Edit", "Edit", null, new { @class = "navigation" }) we could do Html.LinkToAction("Edit").Text("Edit").AddClass("navigation") ? Wouldn't that be much easier to remember and understand?  We can do this if we introduce a semantic model for building our HTML.   What is a Semantic Model? According to Martin Folwer, "a semantic model is an in-memory representation, usually an object model, of the same subject that the domain specific language describes." In our case, the model would be a set of classes that know how to render HTML. By using a semantic model we can free ourselves from dealing with strings and instead output the HTML (typically via ToString()) once we've added all the elements and attributes we desire to the model. There are two primary semantic models available in ASP.NET MVC: MVC 2.0's TagBuilder and FubuMVC's HtmlTags.   TagBuilder TagBuilder is the html builder that is available in ASP.NET MVC 2.0. I'm not a huge fan but it gets the job done -- for simple jobs.  Here's an overview of how to use TagBuilder. See my Tips section below for a few comments on that example. The disadvantage of TagBuilder is that unless you wrap it up with our own classes, you still have to write the actual tag name over and over in your code. eg. new TagBuilder("div") instead of new DivTag(). I also think it's method names are a little too long. Why not have AddClass() instead of AddCssClass() or Text() instead of SetInnerText()? What those methods are doing should be pretty obvious even in the short form. I also don't like that it wants to generate an id attribute from your input instead of letting you set it yourself using external conventions. (See GenerateId() and IdAttributeDotReplacement)). Obviously these come from Microsoft's default approach to MVC but may not be optimal for all programmers.   HtmlTags HtmlTags is in my opinion the much better option for generating html in ASP.NET MVC. It was actually written as a part of FubuMVC but is available as a stand alone library. HtmlTags provides a much cleaner syntax for writing HTML. There are classes for most of the major tags and it's trivial to create additional ones by inheriting from HtmlTag. There are also methods on each tag for the common attributes. For instance, FormTag has an Action() method. The SelectTag class allows you to set the default option or first option independent from adding other options. With TagBuilder there isn't even an abstraction for building selects! The project is open source and always improving. I'll hopefully find time to submit some of my own enhancements soon.   Tips 1) It's best not to have insanely overloaded html helpers. Use fluent builders. 2) In html helpers, return the TagBuilder/tag itself (not a string!) so that you can continue to add attributes outside the helper; see my first sample above. 3) Create a static entry point into your builders. I created a static Tags class that gives me access all the HtmlTag classes I need. This way I don't clutter my code with "new" keywords. eg. Tags.Div returns a new DivTag instance. 4) If you find yourself doing something a lot, create an extension method for it. I created a Nest() extension method that reads much more fluently than the AddChildren() method. It also accepts a params array of tags so I can very easily nest many children.   I hope you have found this post helpful. Join me in my war against HTML literals! I’ll have some more samples of how I use HtmlTags in future posts.
