  • Will Visual Studio 2010 support HTML 5?

    - by Chris
    Since Visual Studio 2010 is slated for release in March of 2010 and HTML 5 is now starting to be used even more widely, I would like to know if Visual Studio will ship with HTML 5 templates, standard controls and support for the more common markup? A definition for support of HTML 5 would be that any new version of Visual Studio should have similar support for code-completion, validation and markup that is currently supported for HTML 4.01 and XHTML 1.0 and 1.1. Update From the Visual Web Develolper Team Blog: HTML 5 intellisense and validation schema for Visual Studio 2008 and Visual Web Developer is for downloading. Follow the instructions posted on the page to install the new scheme. Seems like the Visual Studio Team will be supporting HTML 5 after all.

  • best way to filter out non-representational elements

    - by nonano
    Hi there, I am using phpQuery in order to apply some twaks to editorial content. As its syntax is the same as jQuery, I consider this a dom scripting issue. To get rid of elements which are not representing anything, but wrapping other stuff (like the div in <div><p>blah</p></div> I came up with this selector: ['div:not([align][class][id][style][title][dir][lang][onclick][ondblclick][onmousedown] [onmouseup][onmouseover][onmousemove][onmouseout][onkeypress][onkeydown][onkeyup])'] which looks quite monstrous for a selector simply aming on Divs which just do not have any (valid) attribute. I guess there must be a more straight-forward way to accomplish that, right? Edit: Oh, and I just noticed that it even doesn't do wat I intended to ...

  • How can I determine what text on a webpage will render the largest?

    - by TMG
    I'd like to write a function (ideally in PHP) where I can input a url and return a string corresponding to the hypertext from that webpage which would render the largest in a browser (any standard browser is fine). Getting the webpage and tokenizing things with DOM is pretty straightforward, but what's the best way to calculate ultimate size of the rendered text tokens - how do you account for CSS that includes px, em, % etc. for different font sizes. Anyone done something like this before I go and re-invent the wheel? Thanks in advance.

  • jquery switch element classes

    - by Sobakinet
    Please take a look here: http://jsfiddle.net/ZUd27/7/ What I need: There are several elements. One of them is active and visible. If I hover over any inactive element, it becomes visible and active. The previously active element becomes inactive. On mouseout, nothing happens - the last hovered element stays active. My problems: The first active element always stays active (in DOM?). It becomes invisible, but on next mouseover nothing happens. Other elements don't behave as they should. If one of them is active, on next mousein it becomes invisible. thx

  • HTML format using Java mail in android

    - by TheDevMan
    I am trying to implement an HTML format mail using the Java mail in android. I would like to get results like this: When I look at the html format sent from lookout in my GMAIL. I don't see any link, but just has this format: [image: Lookout_logo] [image: Signal_flare_icon] Your battery level is really low, so we located your device with Signal Flare. I was trying the following: Properties props = System.getProperties(); props.put("mail.smtp.starttls.enable", "true"); // added this line props.put("mail.smtp.host", host); props.put("mail.smtp.user", from); props.put("mail.smtp.password", pass); props.put("mail.smtp.port", "587"); props.put("mail.smtp.auth", "true"); javax.mail.Session session = javax.mail.Session.getDefaultInstance(props, null); MimeMessage message = new MimeMessage(session); message.setFrom(new InternetAddress(from)); InternetAddress[] toAddress = new InternetAddress[to.length]; // To get the array of addresses for( int i=0; i < to.length; i++ ) { // changed from a while loop toAddress[i] = new InternetAddress(to[i]); } message.setRecipients(Message.RecipientType.BCC, toAddress); message.setSubject(sub); //message.setText(body); body = "<!DOCTYPE html><html><body><img src=\"http://en.wikipedia.org/wiki/Krka_National_Park#mediaviewer/File:Krk_waterfalls.jpg\">"; message.setContent(body, "text/html; charset=utf-8"); Transport transport = session.getTransport("smtp"); transport.connect(host, from, pass); transport.sendMessage(message, message.getAllRecipients()); transport.close(); When I look at the html format sent with the above code. I get the following: <!DOCTYPE html><html><body><img src="http://en.wikipedia.org/wiki/Krka_National_Park#mediaviewer/File:Krk_waterfalls.jpg> How to make sure the user will not be able to see any html code or URL link like the mail sent by LOOKOUT? Thanks!

  • Image visualization with canvas. How to resize them?

    - by Luca Matteis
    I'm building a website photo gallery for a friend. Images are loaded as simple DOM image objects (<img src="" />), and the size of these images is based on the browser size. So I resize them with CSS. This isn't an optimal solution since CSS resizing seems to change the quality of the image and pixelate it quite a bit. I was thinking of rendering the image with canvas and then resize it with that so that the quality remains effective, but I can't find any info about this online. Any ideas?

  • JQuery div tag has children in FireFox but not Chrome

    - by John Edwards
    I am using JQuery ajax to load images from a url, display them, and then place a button on top of each image. The code works in firefox, but in chrome, the div parent "photos" that should have all the children(one child div "photo" for each image received from the url) is 0. I have tried read() and load(), but nothing seems to work. If I run alert($('#photos').children().size()); in the Chrome console it returns the children. But at execution it returns 0. Any ideas? $(window).load(function () { $("p").text("The DOM is now loaded and can be manipulated."); //returns 0 in chrome, but 10 in firefox alert($('#photos').children().size()); $('#photos').children().each(function() { //do stuff

  • What's your take on this Javascript thingy?

    - by Nischal
    We've been having a discussion at our workplace on this with some for and some against the behavior. Wanted to hear views from you guys : <html> <body> <div> Test! <script> document.body.removeChild(document.getElementsByTagName('div')[0]); </script> </div> </body> </html> Should the above script work and do what it's supposed to do? First, let's see what's happening here : I have a javascript that's inside the <div> element. This javascript will delete the child node within body which happens to hold the div inside which the script itself exists. Now, the above script works fine in Firefox, Opera and IE8. But IE6 and IE7 give an alert saying they cannot open the page. Let's not debate on how IE should have handled this (they've accepted it as a bug and hence fixed it in IE8). The point here is since the 'SCRIPT' tag itself is a part of DOM, should it be allowed to do something like this? Should it even exist after such an operation?

  • Firefox DOMParser problem

    - by Michael
    For some reason DOMParser is adding some additional #text elements for each newline \n for this url http://rt.com/Root.rss ...as well as many other RSS I've tried. I checked cnn/bbc feeds, they don't have newlines and dom parser handling them nicely. So I have to add the following before parsing it var xmlText = htmlText.replace(/\n[ ]*/g, ""); var xmlDoc = parser.parseFromString(xmlText, "text/xml"); Server is returning text/xml. var channel = xmlDoc.documentElement.childNodes[0]; this returning \n without my code above and channel with correction.

  • Memory leak in Mozilla when unloading stylesheets

    - by KaptajnKold
    I'm working with Mozilla v1.7.12 on a constrained device (a Motorola set-top box) trying to resolve some memory leaks. When I dynamically load a stylesheet which refers to some large images, I can see that the amount of consumed memory increases in correspondance with the size of the images. This is what I would expect. Then, when I remove the stylesheet from the DOM, I would expect the memory to be freed. However, this does not happen. This is a problem, because the web application I'm working on needs to be able to dynamically load and and unload stylesheets potentially many times in the lifetime of the page. My question therefore is this: Is what I'm seeing expected behavior or is it a known bug? Is there a way to work around this? I should point out that I've set the expires header to -1 on all the images in the stylesheet.

  • How access Ajax generated source ?

    - by Rorchackh
    Hello everyone, I created a php file that return dynamically generated text. This text is returned with a div id. When I retrieve that text using Ajax as responseText. I would like to access the properties of that div using javascript, which is impossible since that new text is not added to the DOM. My question is, how can i access that div using either raw javascript or frameworks (am somewhat familiar with jQuery) ? It may be useful to note that the div can be accessed using CSS. Thank you.

  • Get CSS style from PHP

    - by rpSetzer
    I am parsing pages using Simple DOM parser. It is neat, but I would like to get the applied css style for each element. Not only the inline styles, but every style it applies to that element, being it inline, in-page or external. Is there a class that does that? If not, how would you do it? I do not really care about overriding styles, cascade, or browser specific styles. Having all the directly applied styles would suffice.

  • Should a "script" tag be allowed to remove itself?

    We've been having a discussion at our workplace on this with some for and some against the behavior.

Edit: Firefox, Opera, IE9 etc. do not remove the 'script' tag if I run the above code. But, document.getElementsByTagName('script').length returns 0! To understand what I mean, add alert(document.getElementsByTagName('script').length); before and after document.body.removeChild(document.getElementsByTagName('div')[0]); in the code above.

  • TinyFluidGrid – a clean and lightweight css framework

    - by Guy Harwood
    I've been using the 960 Grid system for a while on some of my personal projects and if like me you are no css ninja its convenient for sidestepping the usual nightmare of a good cross browser layout, and allows you to move on to the nitty gritty code and functionality. I just stumbled across a new layout generator that looks rather snazzy and has the functionality to back it up.  TinyFluidGrid generates exactly that – a tiny fluid grid! Worth a look.

  • Safari Mobile Multi-Line <Select> aka GWT Multi-Line ListBox

    - by McTrafik
    Hi guys. Working on a webapp here that must run on the iPad (so, Safari Mobile). I have this code that works fine in just about anything except iPad: <select class="gwt-ListBox" size="12" multiple="multiple"> <option value="Bleeding Eyelashes">Bleeding Eyelashes</option> <option value="Smelly Pupils">Smelly Pupils</option> <option value="Bushy Eyebrows">Bushy Eyebrows</option> <option value="Green Vessels">Green Vessels</option> <option value="Sucky Noses">Sucky Noses</option> </select> What it's supposed to look like is a box with 12 lines ans 5 of them filled up. It works fine in FF, IE, Chrome, Safari Win. But, when I open it on iPad, it's just a single line! Styling it with CSS doesn't work. It just makes the single line bigger if I set the height. Is there a way to make it behave the same way as in normal browsers, or do I nave to make a custom component? Thanks.

  • eLearning event on HTML5 for Mobile with jQuery Mobile

    - by Wallym
    I'll be doing an eLearning event on HTML5 for Mobile with jQuery Mobile. There will also be a few items sprinkled in on ASP.NET Razor. Mobile development is a hot item. Customers are buying iPhones, iPads, Android devices, and many other mobile computing devices at an ever increasing record pace. Devices based on iOS and Android are nearly 80 percent of the marketplace. RIM continues to be dominant in the business area across the world. Nokia's growth with Windows Phone will grow on a worldwide basis. At the same time, clearly web development is a tremendous driver of applications, both on the public Internet and on private networks. How can developers target these various mobile platforms with web technologies? Developers can write web applications that take advantage of each mobile platform, but that is a lot of work. Into this space, the jQuery Mobile framework was developed. This eLearning series will provide an overview of mobile web development with jQuery Mobile, a detailed look at what the jQuery Mobile framework provides for us, how we can customize jQuery Mobile, and how we can use jQuery Mobile inside of ASP.NET.Link: http://elearning.left-brain.com/event/mobile-web-development

  • Is the W3 standard a major factor when google decides SERP position?

    I have a dynamic php website which index only has around 800 errors according to the w3 validator online.

Secondly, will the errors affect my SERP ranking? ie, will me fixing these errors as good as I can increase my Google search position? Thanks

  • Arguments to homologate Firefox in a Company

    - by Vegetus
    I developed a web project for my company and this project was designed to use Mozilla Firefox (including the javascript (jQuery)). However, now the company wants the project to be transferred to Internet Explorer. I know that in Google, there are several explanations about Mozilla Firefox, which I can demonstrate to the company. But is there any link showing that Internet Explorer runs the W3C standards and has several justifications for why using Mozilla Firefox? I searched on youtube and slideshare, but both have a very weak argument for me to select them and show to the company. The company where I work is still very naive to keep Internet Explorer. 1) The project is intranet. Only 400 internal employees can access the web. 2) The company argues that Mozilla Firefox is not approved by the company. Any suggestions? Any link which shows that the developers of the world hate Internet Explorer? A link explaining why developers do not like Internet Explorer? After the answers, I'm thinking of making a great slide with all the necessary arguments to the company homologue firefox. And yet, published in slideshare. EDIT: Someone here must be wondering why I have not designed, also for Internet Explorer. Welllll... As the deadline for project completion is always short, I developed the project focused only on Mozilla Firefox, because the browser Mozilla Firefox most respects W3C standards (and javascript too) than Internet Explorer.

  • HTML Markup in einem APEX Tree - ganz einfach per Plugin!

    - by carstenczarski
    Die APEX Tree Region kennt sicherlich jeder APEX-Entwickler. Und vielfach besteht der Bedarf, das Aussehen des APEX Tree mit Hilfe von HTML Markup zu beeinflussen. Leider ist es seit APEX 4.0 nicht mehr möglich, eigenes HTML-Markup in einen APEX-Tree aufzunehmen - aus Sicherheitsgründen (Schutz vor Cross-Site-Scripting) werden alle HTML Sonderzeichen maskiert. Wenn kein XSS-Risiko besteht (die vom Tree dargestellten Inhalte basieren nicht auf Benutzereingaben und werden komplett vom Entwickler bestimmt), kann dies mit wenigen Zeilen JavaScript und jQuery-Code erreicht werden. Damit es noch einfacher wird,  haben wir die Funktionalität für Sie in einem APEX-Plugin gekapselt. Und so funktioniert es: APEX Plugin "HTML Markup for APEX Tree Region" herunterladenhttp://apex-plugin.com/oracle-apex-plugins/dynamic-action-plugin/html-markup-for-apex-tree_174.html APEX Plugin in die Anwendung importieren APEX Tree Region erzeugen und eigene Ersetzungen für HTML-Sonderzeichen verwenden, also bspw."[" für "<", "]" für ">" und "§" für "&". Eine neue dynamische Aktion erzeugen, die beim Laden der Seite ausgeführt wird und mit Hilfe des Plugins die Ersetzungen im Tree durch die "richtigen" HTML-Sonderzeichen ersetzt. Fertig. Wie das Plugin wirkt, können Sie sich auf einer Demo-Seite ansehen.

  • Why does max-width behave counter intuitively on columns in a table? [migrated]

    - by Nate
    Basically, I have a stretchy table, I want my label column to be fixed width and my data column to be dynamically sized. My inclination would be to set the max-width via CSS on my label column. However, this has the opposite effect. I've created a jsfiddle that replicates this. (Re-size the window to see the left column dynamically sized and the right column fixed size) On my own site, I see the same behavior and it happens in IE and Chrome. If I switch it, and set max-width on the data column, everything behaves as I want, but it feels backwards to me. Am I doing something wrong here?
