  • Completely bizarre Firefox CSS bug

    - by Jason
    I've been doing front end development for a long time, and I have NEVER come across a bug like this before... Save the following HTML to a file and view it in Firefox (mine is 3.6.3): <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> body { font-family: Helvetica, Sans-Serif;} h2 {font-weight: normal;} </style> </head> <body> <h2>Some normal text <strong>some bold text</strong> weird huh?</h2> </body> </html> If you don't want to give it a shot the output is like your cat walked across your keyboard while character map was turned on, except in the strong tags. I feel like this may be a font issue? When I get rid of font-weight: normal it goes back to normal, but I don't want everything to be bolded in my h2... Anyone have any ideas? More importantly, is anyone able to reproduce this?? Thanks.

  • JW Player can not play m3u8 stream?

    - by why
    with check this example, http://developer.longtailvideo.com/player/branches/adaptive/test/provider.html , I tried the example myself, There is my code: <html> <head> <script type="text/javascript" src="jwplayer.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <title>Provider tests</title> <style> body { padding: 50px; font: 13px/20px Arial; background: #EEE; } form { margin-top: 20px; } #player { -webkit-box-shadow: 0 0 5px #999; background: #000; } ul { margin-top: 40px; padding: 0 0 0 20px; list-style-type: square; } </style> </head> <body> Test M3U8 <div id="player">You need Flash to play these tests</div> <script type="text/javascript"> jwplayer("player").setup({ file: '../m3u8/index.m3u8', flashplayer: 'player.swf', provider:'adaptiveProvider.swf', height: 360, width: 640 }); function loadStream(url) { jwplayer("player").load({file: url,provider: 'adaptiveProvider.swf'}); jwplayer("player").play(); return false; } $(document).ready(function() { loadStream('http://localhost/m3u8/index.m3u8'); }); </script> <ul id="streamlist"></ul> <div id="panel"></div> </body> </html> But the Jw Play can not work BTW: my vlc can play http://localhost/m3u8/index.m3u8 well

  • Loading Facebook fb:profile-pic via AJAX in Facebook Connect site

    - by mbrevoort
    After a page loads, I'm making an AJAX request to pull down an HTML chunk that contains tags representing a Facebook user profile picture. I append the result to a point in the DOM but the logos don't load, instead all I see is the default silhouette. Here's simply how I'm loading the HTML chunk with jQuery $.ajax({ url: "/facebookprofiles" success: function(result) { $('#profiles').append(result); } }); The HTML that I'm appending is a list of diffs like this: <div class="status Accepted"> <fb:profile-pic class="image" facebook-logo="true" linked="true" size="square" uid="1796055648"></fb:profile-pic> <p> <strong>Corona Kingsly</strong>My Status Update<br/> <span style="font-size: 0.8em">52 minutes ago</span> </p> </div> Any ideas? I assume the fb tags are not being processed once the dom is loaded. Is there any way to make that happen? I'm not seeing any exceptions or errors in my Firebug console. Thanks

  • Help with my PHP template class

    - by blerh
    I want to separate the output of HTML from my program code in my projects, so I wrote a very simple database class. <?php class Template { private $template; function load($filePath) { if(!$this->template = file_get_contents($filePath)) $this->error('Error: Failed to open <strong>' . $filePath . '</strong>'); } function replace($var, $content) { $this->template = str_replace("{$var}", $content, $this->template); } function display() { echo $this->template; } function error($errorMessage) { die('die() by template class: <strong>' . $errorMessage . '</strong>'); } } ?> The thing I need help with is the display() method. Say for example I use this code: $tplObj = new Template(); $tplObj->load('index.php'); $tplObj->replace('{TITLE}', 'Homepage'); $tplObj->display(); And the index.php file is this: <html> <head> <title>{TITLE}</title> </head> <body> <h1>{TITLE}</h1> <?php if($something) { echo '$something is true'; } else { echo '$something is false'; } ?> </body> </html> I'm just wondering if the PHP code in there would be run? Or would it just be sent to the browser as plaintext? I was using eval() in my template class but I hate that function :P Thanks.

  • PHP - "Fat Free Framework" Find Methods and Showing Results in Template

    - by user1672808
    Just started trying the "Fat Free Framework" I'm building a site using a MySQL DB with 265 fields, and 5000+ rows in the DB; I can load() a specific record easily, no problems. When using find(), afind(), and even "select()", template will show blank lines or lines with "filler" text, with the correct number of rows for the query results, but no text/data from the DB itself; Same problem whether using objects or simply arrays from result (afind() and find()). I've copied/pasted the code verbatim from examples and from documentation, with only the DB specific items changed. Still, no luck. CODE IN PHP FILE (function from CLASS): static function home() { $featured=new Axon('boats'); $F3::set('boatlist',$featured->afind('D_CustomerID=173')); F3::set('content',TEMPLATE_DIR .'/home.html'); echo Template::serve(TEMPLATE_DIR .'/layout.html'); } TEMPLATE home.html: <div class="span8"> <h3> Featured Boats </h3> <F3:repeat group="{{@boatlist}}" value="{{@boat}}"> <div style="margin-left: 2em" class="thumbnails"> <p> <a href="boat/{{@boat['D_BoatNum']}}">{{trim(@boat['D_Description'])}}</a> by {{@boat['D_CustomerID']}} </p> <p> {{@boat['D_Price']}} </p> </div> </F3:repeat> </div> The number of rows this produces coincides with the correct number of rows in the DB. However, the actual data from each field does not show. Any ideas?

  • Error with Property Validation in Form Submission in ASP.NET MVC

    - by Maxim Z.
    I have a simple form on an ASP.NET MVC site that I'm building. This form is submitted, and then I validate that the form fields aren't null, empty, or improperly formatted. However, when I use ModelState.AddModelError() to indicate validation errors from my controller code, I get an error when my view is re-rendered. In Visual Studio, I get that the following line is highlighted as being the location of the error: <%=Html.TextBox("Email")%> The error is the following: NullReferenceException was unhandled by user code - object reference not set to an instance of an object. My complete code for that textbox is the following: <p> <label for="Email">Your Email:</label> <%=Html.TextBox("Email")%> <%=Html.ValidationMessage("Email", "*") %> </p> Here's how I'm doing that validation in my controller: try { System.Net.Mail.MailAddress address = new System.Net.Mail.MailAddress(email); } catch { ModelState.AddModelError("Email", "Should not be empty or invalid"); } return View(); Note: this applies to all of my fields, not just my Email field, as long as they are invalid.

  • Redeclared javascript global variable overrides old value in IE

    - by Yousuf Haider
    (creating a separate question after comments on this: http://stackoverflow.com/questions/2634410/javascript-redeclared-global-variable-overrides-old-value) I am creating a globally scoped variable using the square bracket notation and assigning it a value inside an external js file. In another js file I declare a var with the same name as the one I just created above. Note I am not assigning a value. Since this is a redeclaration of the same variable the old value should not be overriden as described here: http://www.w3schools.com/js/js_variables.asp Create 2 javascript files with the following content : Script1 //create global variable with square bracket notation window['y'] = 'old'; Script2 //redeclaration of the same variable var y; if (!y) y = 'new'; alert(y); //shows New instead of Old in IE Include these 2 files in your html file <html> <head></head> <body> <script type="text/javascript" src="my.js"></script> <script type="text/javascript" src="my2.js"></script> </body> </html> Opening this page in Firefox and Chrome alerts 'old' which is the expected behavior. However in IE 8 the page will actually alert 'new' Any ideas on why this happens on IE ?

  • Ajax/jQuery problem

    - by Lucho
    Hi, I'm rookie when it comes to Ajax and jQuery and needs some help... The following url produces an xml-file that I want to use on my page: http://ws.spotify.com/search/1/track?q=foo When I use firebug it seems like nothing comes back. What have I done wrong? This is what my code looks like: <!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"> <head> <title></title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ $.ajax({ url: 'http://ws.spotify.com/search/1/track?q=foo', type: 'GET', contentType: "application/xml; charset=utf-8", error: function(){ alert('Error loading XML document'); }, success: function(xml){ alert("success"); $(xml).appendTo("#result"); } }); }); </script> </head> <body> <div id="result"> </div> </body> </html>

  • JavaScript on jQuery created code never gets called

    This is my view in ASP.NET MVC. <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Administration.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="HeadContent" runat="server"> <script type="text/javascript"> var ddlContentTypes; $(document).ready(function () { ddlContentTypes = $("#ContentTypes"); ddlContentTypes.bind("change", loadCreate); loadCreate(); }); function loadCreate() { var typeId = $("#ContentTypes option:selected").val(); $.get('~/' + typeId + '/Create', function (data) { $("#CreateForm").html(data); }); $("fieldset input").each(function (index, item) { $(item).attr("disabled", true); }); } </script> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server"> <h2> <%=Resources.Localize.CreateWidget %></h2> <p> <% Html.RenderPartial("ContentTypeSelector"); %></p> <div id="CreateForm"> </div> </asp:Content> As you can see, it loads some HTML (actually user control) and adds it to the CreateForm div. This actually works fine. The problem is this $("fieldset input").each(function (index, item) { $(item).attr("disabled", true); }); never runs. The fieldset tag is in the response, so you don't see it here but it's there - everything is returned back fine (I checked with Firebug). Why do the above two lines of JS never run or have any effect?

  • How do you print from a popup window in javascript?

    - by sglantz
    I have a .Net application that dynamically creates a small HTML page and pops it up in a new window using the javascript document.open method. Everything with that functionality is working fine. Now I want to add a button to the HTML page that prints the page. I have tried using the following code to no avail: <a href='print.html' onClick='window.print();return false;'> <img src='images/printer.png' height='32px' width='32px'></a> When the button is clicked in the popup window, nothing happens. But when the source code of of this page is saved and loaded in a browser as a separate page, the print button works perfectly. So it would appear that the problem is caused by the fact that the code is in a popup window. Does anyone know a way to fix this problem or any alternatives? EDIT: Other method that I have tried with the same results: <input type='button' onclick='window.print()' value='Print' /> and <a href='javascript:window.print()'> <img src='images/printer.png' height='32px' width='32px'></a>

  • reddit style voting with django

    Hay i need to hand implemeneting a voting system into a model. I've had a huge helping hand from Mike DeSimone making this work in the first place, but i need to expand upon his work. Here is my current code View def show_game(request): game = Game.objects.get(pk=1) discussions = game.gamediscussion_set.filter(reply_to=None) d = { 'game':game, 'discussions':discussions } return render_to_response('show_game', d) Template <ul> {% for discussion in discussions %} {{ discussion.html }} {% endfor %} </ul> Model class GameDiscussion(models.Model): game = models.ForeignKey(Game) message = models.TextField() reply_to = models.ForeignKey('self', related_name='replies', null=True, blank=True) created_on = models.DateTimeField(blank=True, auto_now_add=True) userUpVotes = models.ManyToManyField(User, blank=True, related_name='threadUpVotes') userDownVotes = models.ManyToManyField(User, blank=True, related_name='threadDownVotes') def html(self): DiscussionTemplate = loader.get_template("inclusions/discussionTemplate") return DiscussionTemplate.render(Context({ 'discussion': self, 'replies': [reply.html() for reply in self.replies.all()] })) DiscussionTemplate <li> {{ discussion.message }} {% if replies %} <ul> {% for reply in replies %} {{ reply }} {% endfor %} </ul> {% endif %} </li> As you can see we have 2 fields userUpVotes and userDownVotes on the model, these will calculate how to order the discussions and replies. How would i implement these 2 fields to order the replies and discussions based on votes? Any help would be great!

  • MVC: model of type Nullable<T>

    - by Fyodor Soikin
    I have a partial view that inherits from ViewUserControl<Guid?> - i.e. it's model is of type Nullable<Guid>. Very simple view, nothing special, but that's not the point. Somewhere else, I do Html.RenderPartial( "MyView", someGuid ), where someGuid is of type Nullable<Guid>. Everything's perfectly legal, should work OK, right? But here's the gotcha: the second argument of Html.RenderPartial is of type object, and therefore, Nullable<Guid> being a value type, it must be boxed. But nullable types are somehow special in the CLR, so that when you box one of those, you actually get either a boxed value of type T (Nullable's argument), or a null if the nullable didn't have a value to begin with. And that last case is actually interesting. Turns out, sometimes, I do have a situation when someGuid.HasValue == false. And in those cases, I effectively get a call Html.RenderPartial( "MyView", null ). And what does the HtmlHelper do when the model is null? Believe it or not, it just goes ahead and takes the parent view's model. Regardless of it's type. So, naturally, in those cases, I get an exception saying: "The model item passed into the dictionary is of type 'Parent.View.Model.Type', but this dictionary requires a model item of type 'System.Guid?'" So the question is: how do I make MVC correctly pass new Nullable<Guid> { HasValue = false } instead of trying to grab the parent's model? Note: I did consider wrapping my Guid? in an object of another type, specifically created for this occasion, but this seems completely ridiculous. Don't want to do that as long as there's another way. Note 2: now that I've wrote all this, I've realized that the question may be reduced to how to pass a null for model without ending up with parent's model?

  • comparing strings from two different sources in javascript

    - by andy-score
    This is a bit of a specific request unfortunately. I have a CMS that allows a user to input text into a tinymce editor for various posts they have made. The editor is loaded via ajax to allow multiple posts to be edited from one page. I want to be able to check if there were edits made to the main text if cancel is clicked. Currently I get the value of the text from the database during the ajax call, json_encode it, then store it in a javascript variable during the callback, to be checked against later. When cancel is clicked the current value of the hidden textarea (used by tinymce to store the data for submission) is grabbed using jquery.val() and checked against the stored value from the previous ajax call like this: if(stored_value!=textarea.val()) { return true } It currently always returns true, even if no changes have been made. The issue seems to be that the textarea.val() uses html entities, whereas the ajax jsoned version doesn't. the response from ajax in firebug looks like this: <p>some text<\/p>\r\n<p>some more text<\/p> the textarea source code looks like this: &lt;p&gt;some text&lt;/p&gt; &lt;p&gt;some more text&lt;/p&gt; these are obviously different, but how can I get them to be treated as the same when evaluated? Is there a function that compares the final output of a string or a way to convert one string to the other using javascript? I tried using html entities in the ajax page, but this returned the string with html entities intact when alerted, I assume because json_encoding it turned them into characters. Any help would be greatly appreciated.

  • Getting Started with Ruby & Ruby on Rails

    - by JakeTheSnake
    Some background: I'm a jack-of-all traits, one of which is programming. I learned VB6 through Excel and PHP for creating websites and so far it's worked out just fine for me. I'm not CS major or even mathematically inclined - logic is what interests me. Current status: I'm willing to learn new and more powerful languages; my first foray into such a route is learning Ruby. I went to the main Ruby website and did the interactive intro. (by the way, I'm currently getting redirected to google.com when I try the link...it's happening to other websites as well...is my computer infected?) I liked what I learned and wanted to get started using Ruby to create websites. I downloaded InstantRails and installed it; everything so far has been fine - the program starts up just fine, and I can test some Ruby code in the console. However my troubles begin when I try and view a web page with Ruby code present. Lastly, my problem: As in PHP, I can browse to the .php file directly and through using PHP tags and some simple 'echo' statements I can be on my way in making dynamic web pages. However with the InstantRails app working, accessing a .rb or .rhtml page doesn't produce similar results. I made a simple text file named 'test.rb' and put basic HTML tags in there (html, head, body) and the Ruby tags <%= and % with some ruby code inside. The web page actually shows the tags and the code - as if it's all just plain HTML. I take it Ruby isn't parsing the page before it is displayed to the user, but this is where my lack of understanding of the Ruby environment stops me short. Where do I go from here?

    First, I would to thank everyone for all the help they provide via this website. It has gotten me to the point of almost being able to release my first iPhone app! Okay, so the last part I have is this: I have a game that allows users to save their high scores. I update a plist file which contains the users Name, Level, and score. Now I want to create a screen that will display the top 20 high scores. What would be the best way to do this? At first I thought possibly creating an HTML file with this info but am not even sure if that is possible. I would need to read the plist file, and then write it out as HTML. Is this possible? To write a file out as HTML? Or an even better question, is there a better way? Thanks in advance for any and all help! Geo...

  • Issue encondig java->xls

    - by Xerg
    This is not a pure java question and can also be related to HTML I've written a java servlet that queries a database table and shows the result as a html table. The user can also ask to receive the result as an Excel sheet. Im creating the Excel sheet by printing the same html table, but with the content-type of "application/vnd.ms-excel". The Excel file is created fine. The problem is that the tables may contain non-english data so I want to use a UTF-8 encoding. PrintWriter out = response.getWriter(); response.setContentType("application/vnd.ms-excel:ISO-8859-1"); //response.setContentType("application/vnd.ms-excel:UTF-8"); response.setHeader("cache-control", "no-cache"); response.setHeader("Content-Disposition", "attachment; filename=file.xls"); out.print(src); out.flush(); The non-english characters appear as garbage (áéíóú) Also I tried converting to bytes from String byte[] arrByte = src.getBytes("ISO-8859-1"); String result = new String(arrByte, "UTF-8"); But I Still getting garbage, What can I do?.

  • How to develop modular web UIs with Django?

    - by nh2
    When doing larger sites in "big business", you most probalbly work in a team with several developers. Let's say dev A makes a form to insert new user data, B creates a user list, C makes some privilege administration and D does crazy statistic graphs work with image generation and so on. Each dev begins to develop his own component, creates a view and a template and tests that independently, until each component works. Now, the client wants to have all those components on one bit HTML page. How to achieve this? How to assemble different views/templates in a form of composition so that they remain modular and can be developed and tested independently? It seems inheritance is not the way to go because all of those UI components are equal and there is no hierarchy. The idea of the assembling template is something like <html> <head> // include the css for the components and their assembly </head> <body> // include user data form here <some containers, images, and so on> // show user list // show privilege administration in this part // and finally, the nice statistic graphs // perhaps, we want to display some other components here in future </body> </html> I have not found an answer on the net yet. Most people come up with one big template which just implements all of the UI functionality, removing all modularity. Each component shall have its own template and view dealing only with that component developed by one person each, and they then shall be sticked together just like bricks. I would highly appreciate any hints!

  • What's the scope of a Javascript variable declared in a for() loop?

    - by Dylan Beattie
    Check out the following snippet of HTML/Javascript code: <html> <head> <script type="text/javascript"> var alerts = []; for(var i = 0; i < 3; i++) { alerts.push(function() { document.write(i + ', '); }); } for (var j = 0; j < 3; j++) { (alerts[j])(); } for (var i = 0; i < 3; i++) { (alerts[i])(); } </script> </head><body></body></html> This outputs: 3, 3, 3, 0, 1, 2 which isn't what I was expecting - I was expecting the output 0, 1, 2, 0, 1, 2, I (incorrectly) assumed that the anonymous function being pushed into the array would behave as a closure, capturing the value of i that's assigned when the function is created - but it actually appears that i is behaving as a global variable. Can anyone explain what's happening to the scope of i in this code example, and why the anonymous function isn't capturing its value?

  • ComDlg32.ocx Error: Object doesn't support this property or method

    - by abhilashca
    I'm developing an html editor using ComDlg32.ocx (Commom Dialog Control), using HTML and VBScript. My exact requirement was to prompt Open/Save/Color/Print/Font dialog boxes.Ive written code for prompting Save file dialog box. Also I've added a license file using LPK Tool onto my webpage. My html-source looks like: <body> <!-- lpk file --> <object classid="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"> <param name="LPKPath" value="License/comdlg.lpk" /> </object> <!-- Microsoft Common Dialog Control --> <object classid="CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB" codebase="http://activex.microsoft.com/controls/vb6/COMDLG32.CAB" id="objComDlg"></object> </body> Now, here comes my error. Whenever I try to call the vbscript for prompting the Save File dialog box, Im getting an error as : Object doesn't support this property or method: 'objComDlg.Filter' If I comment out the objComDlg.Filter then the error move on to objComDlg.DialogTitle and thus it goes on. And my VBScript look like: FILE_FORMATS = "Rich Text Format (*.rtf)|*.rtf|Microsoft Word (*.doc)|*.doc|ANSI Text Document (*.txt)|*.txt" objComDlg.Filter = FILE_FORMATS <--- Error shows here objComDlg.DialogTitle = "Save As " objComDlg.Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly objComDlg.CancelError = True objComDlg.ShowSave Does anyone have an idea why this is happening? Is there any proper documentation for using this particular ActiveX control? My current development is in stand-still due to this error. Any help will be appreciated. Looking forward for your response. BTW, I'm using Windows XP SP3 and IE8 for my development. Thanks.
