  • assigning variables to DOM event listeners when iterating

    - by ptrn
    I'm thinking there's something basic stuff I'm missing here; for (var i=1; i<=5; i++) { var o = $('#asd'+i); o.mouseover(function() { console.info(i); }); } When hovering over the five different elements, I always get out the last value from iteration; the value 5. What I want is different values depending of which element I'm hovering, all from 1 to 5. What am I doing wrong here?

  • How to retrieve a style's value in javascript?

    - by stan
    I am looking for a way to retrieve the style from an element that has a style set upon it by the style tag. <style> #box {width: 100px;} </style> In the body <div id="box"></div> I'm looking for straight javascript without the use of libraries. I tried the following, but keep receiving blanks: alert (document.getElementById("box").style.width); alert (document.getElementById("box").style.getPropertyValue("width")); I noticed that I'm only able to use the above if I have set the style using javascript, but unable to with the style tags.

  • How Long: Converting HTML to Jooma pages

    - by George
    Hello Everyone, I would really appreciate your help with finding out how long it takes a 1-3 year experenced programmer to convert a few HTML pages into joomla 1.5 dynamic pages. I know that some of it depends on how complex the pages are but i'm talking about average pages. That's my first question, my other question is how long will it take a 1-3 year experenced programmer to install all of these componants: Video module, photo gallery module, vertuemart shopping cart. I pay programmers to do this work but i have to make as sure as i can that i'm not over paying them. Thanks in advance for answering these two questions...George

  • Silverlight 4 Assembly Sharing Problem

    - by jeffn825
    I have a WPF .NET 4.0 class library referencing a Silverlight 4 class library. The SL library compiles fine but when I compile the WPF class library, I get: Error 2 Unknown build error, 'Cannot resolve dependency to assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.' MyProj.Presentation.Wpf I figure the problem must be similar to the one mentioned here: http://markti.spaces.live.com/blog/cns!D92CF278F0F91957!273.entry but my WPF library doesn't contain any XAML that references a user control from my SL library. In fact, my SL library doesn't have any XAML in it at all. It does, however, have several shared DependencyObjects, such as an EventCommander (binding UI element events to Commands), and some DataTemplate helpers. Is there any way I can narrow down the problem here? And has anyone found a way of effectively referencing UI elements in a SL4 project from .NET 4.0? Thanks.

  • Helper functions & prototype methods to replace heavy frameworks?

    - by Rob
    All frameworks aside, what are some of the common helper functions/prototype methods you use on a daily basis? Please note I am not arguing against frameworks. I've simply found that the majority of what I do on a daily basis can, most often, be done with a few dozen Array, String and Element.prototype methods. With the addition of a few helper functions like $ (getElementsById) and $$$ (getElementsByClass), I am able to satisfy some of the core benefits, however basic, of a much heavier framework. If you were to collect a small library of basic methods and functions to replace the core functionality of some of the popular frameworks, what would they be?

  • Why does an onclick property set with setAttribute fail to work in IE?

    - by Aeon
    Ran into this problem today, posting in case someone else has the same issue. var execBtn = document.createElement('input'); execBtn.setAttribute("type", "button"); execBtn.setAttribute("id", "execBtn"); execBtn.setAttribute("value", "Execute"); execBtn.setAttribute("onclick", "runCommand();"); Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run. execBtn.onclick = function() { runCommand() }; BAD IDEAS: You can do execBtn.setAttribute("onclick", function() { runCommand() }); but it will break in IE in non-standards mode according to @scunliffe. You can't do this at all execBtn.setAttribute("onclick", runCommand() ); because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do execBtn.setAttribute("onclick", runCommand);

  • Error Messaged and Error Code design

    - by Ved
    We are designing set of web services which will return XML string in response. These are RESTFul services so I will have to send exception inside element. I am planing to design set of Error code which can help me determine where level occured just by looking at the code. For Example 1000 - Application Level 2000 - DB level 3000 - Network level so if I have error message then I can know right away that this was an application level error and it came from 1st business module. I am not very experience in this so I would love to here your thoughts and criticism. Thanks

  • Using Simple HTML Dom to match a string on the page

    - by Abs
    Hello all, How do I match and get the flash vars on a HTML page? I am using simple HTML dom element and I am able to narrow down to a div containing the text I need. <script type="text/javascript"> var s1 = new SWFObject("jw4.4/player.swf", "player", "400", "50", "9"); s1.addParam("allowfullscreen", "true"); s1.addParam('allowscriptaccess','always'); s1.addVariable("width","400"); s1.addVariable("height","50"); s1.addVariable("overstretch", "false"); s1.addParam('flashvars',"this_id=/tg&amp;autostart=true"); s1.write("container"); How do I get the value of this_id, so I want to return /tg? What would I put in find? Or do i have to use something else? $html = file_get_html("$url"); $file_path = $html->find('this_id=/'); Thanks all for any help

  • Define variable in variable/parameter and use in javascript?

    - by Ross
    I want to defined a variable/parameter in CSS and access it by javascript. What is the best way of doing this? One option I thought of would be to place a cutsom attribute on the body element, then access that attribute via jQuery. A little more info: I'm defining colour sets in CSS. I've created a function with RaphaelJS to draw a gradient background on the page. I want this function to use a highlight colour (which is not used elsewhere on the DOM) which will be defined in the CSS along with the other colour elements. Thanks

  • SDP media field format

    - by TacB0sS
    Hey, I would like to create a SDP media field with its attributes, and there are a few things I don't understand. I've skimmed and read the relevant RFC and I understand most of what each field means, but what I don't understand is how do I derive from the Audio/Video Format of the JMF, which parameters of the format compose the rtpmap registry entries I need to use. I see many times the fields m=audio 12548 RTP/AVP 0 8 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv these are received from the pbx server I'm connecting to, what do they mean in the terms of the JMF audio format properties. (I do understand these are standard audio format commonly used in telecommunication) UPDATE: I was more wondering about the format parameter '0 8 101' at the end of m=audio 12548 RTP/AVP 0 8 101 Thanks in advance, Adam Zehavi.

  • Why is Visual Studio 2008 slow with Firefox?

    - by Edward Tanguay
    I am using Microsoft Visual Web Developer 2008 Express. I've made an ASP.NET MVC site which has 6 CSS files and 6 Javascript files in the HEAD element in the Site.Master file. When I do F5 or CTRL-F5 in Explorer or Opera, the site displays instantly. When I run my site in Firefox, it takes a SECOND for each CSS and each Javascript file on LOCALHOST, i.e. 12 seconds to load on localhost. What might I be able to change in the Firefox settings so it is as fast as Opera and Explorer? NEW INFO: Uninstalled Firebug completely, no yslow, no other add-ons. When I take out the CSS and Javascript files, then Firefox is as fast as the other browsers. What could be taking it so long on a local connection?

  • Loader for images that are in another page that are gathered with ajax, in jQuery

    - by abdullah kahraman
    Hello. Let's say I have a link in "index.php", when I click on that link, it loads, via ajax, a content from a page "content.php" into a div element in "index.php", that has an id of "#content". That content in "content.php" has large images. I want to display an image loader, say "ajax-loader.gif", instead of those large images, until the images are downloaded by client. ( I know how to have an image loader .gif for the images on "index.php". ) How can I achieve this?

  • C# LINQ Where Predicate Type Arguments

    - by blu
    I have an XElement with values for mock data. I have an expression to query the xml: Expression<Func<XElement, bool>> simpleXmlFunction = b => int.Parse(b.Element("FooId").Value) == 12; used in: var simpleXml = xml.Elements("Foo").Where(simpleXmlFunction).First(); The design time error is: The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly' The delegate supplied to Where should take in an XElement and return a bool, marking if the item matches the query, I am not sure how to add anything more to the delegate or the where clause to mark the type. Also, the parallel method for the real function against the Entity Framework does not have this issue. What is not correct with the LINQ-to-XML version?

  • R: Creating Custom Shapes with ggplot

    - by Brandon Bertelsen
    Full Disclosure: This was also posted to the ggplot2 mailing list. (I'll update if I receive a response) I'm a bit lost on this one, I've tried messing around with geom_polygon but successive attempts seem worse than the previous. The image that I'm trying to recreate is this, the colours are unimportant, but the positions are: In addition to creating this, I also need to be able to label each element with text. At this point, I'm not expecting a solution (although that would be ideal) but pointers or similar examples would be immensely helpful. One option that I played with was hacking scale_shape and using 1,1 as coords. But was stuck with being able to add labels. The reason I'm doing this with ggplot, is because I'm generating scorecards on a company by company basis. This is only one plot in a 4 x 10 grid of other plots (using pushViewport) Note: The top tier of the pyramid could also be a rectangle of similar size.

  • (CKEditor) Looking for exhaustive list of commands and a way to set style...?

    - by humble_coder
    Hi All, I'm currently working with CKEditor (http://ckeditor.com/). I'm looking for: 1) an exhaustive list of commands available by default via 'execCommand'. 2) a mechanism by which to set styles (as in the same way the FONT and SIZE combo boxes do it). I saw the function called 'setStyle' in the documentation, however it seems to require an exact element. I can't for the life of me figure out how to do so based on the selection -- there is no way to use ID or CLASS, as the selected portions have none. I've posted to the forums but they don't seem to be terribly active as far as replies are concerned. Any assistance would be most appreciated. Best.

  • Loop to LINQ Conversion -

    - by Pino
    Ok I have the following, set-up and working great. These lines of code should do a conversion from DAL Entity (Subsonic) to a ViewModel. IList<ProductOptionModel> OptionsRetData = new List<ProductOptionModel>(); foreach (var CurProductOption in this.ProductOptions) { OptionsRetData.Add(CurProductOption.ToDataModel()); } returnData.Options = OptionsRetData.AsEnumerable(); I'd like to convert this to a LINQ single line statment and came up with the following. returnData.Options = this.ProductOptions.Select(o => o.ToDataModel()); and am recieving the following error. Server Error in '/' Application. Sequence contains no matching element So why does the first statment work but not the LINQ and, what steps can I take to resolve it.

  • How does Bitmap.Save(Stream, ImageFormat) format the data?

    - by Matt Jacobsen
    I have a non transparent, colour bitmap with length 2480 and width 3507. Using Bitmap.GetPixel(int x, int y) I am able to get the colour information of each pixel in the bitmap. If I squirt the bitmap into a byte[]: MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Bmp); ms.Position = 0; byte[] bytes = ms.ToArray(); then I'd expect to have the same information, i.e. I can go to bytes[1000] and read the colour information for that pixel. It turns out that my array of bytes is larger than I anticipated. I thought I'd get an array with 2480 x 3507 = 8697360 elements. Instead I get an array with 8698438 elements - some sort of header I presume. In what format the bytes in my array stored? Is there a header 1078 bytes long followed by Alpha, Red, Green, Blue values for every byte element, or something else?

  • Subscribing to a ObservableCollection via reflection

    - by Julian Lettner
    How can I subscribe to a ObservableCollection<??> without knowing the element type of the collection? Is there a way to do this without too many 'magic strings'? This is a question for the .NET version 3.5. I think 4.0 would make my life much easier, right? Type type = collection.GetType(); if(type.IsGenericType && type.GetGenericTypeDefinition() == typeof(ObservableCollection<>)) { // I cannot cast the collection here ObservableCollection<object> x = collection; } Thanks for your time.

  • Adding an IList item to a particular index number

    - by Dr. Zim
    Our Client's database returns a set of prices in an array, but they sometimes don't include all prices, i.e., they have missing elements in their array. We return what we find as an IList, which works great when we retrieve content from the database. However, we are having difficulties setting the elements in the proper position in the array. Is it possible to create an IList then add an element at a particular position in the IList? var myList = new List<Model>(); var myModel = new Model(); myList[3] = myModel; // Something like what we would want to do

  • Help with Event-Based Components

    - by Joel in Gö
    I have started to look at Event-Based Components (EBCs), a programming method currently being explored by Ralf Wesphal in Germany, in particular. This is a really interesting and promising way to architect a software solution, and gets close to the age-old idea of being able to stick software components together like Lego :) A good starting point is the Channel 9 video here, and there is a fair bit of discussion in German at the Google Group on EBCs. I am however looking for more concrete examples - while the ideas look great, I am finding it hard to translate them into real code for anything more than a trivial project. Does anyone know of any good code examples (in C# preferably), or any more good sites where EBCs are discussed?
