  • jquery .add() is weird

    - by phil
    Hi folks. Why all elements turn red? I only intend to turn <p> red. <ul> <li>list item 1</li> <li>list item 2</li> <li>list item 3</li> </ul> <p>a paragraph</p> <script> $('li').add('p').css('background-color', 'red'); </script>

  • Unable to get index from jQuery UI slider range

    - by Phil.Wheeler
    I'm having a hell of a time trying to get (what I thought was) a simple index from a collection of multiple sliders. The HTML is as follows: <div id="left-values" class="line"> <span id="l1" style="padding: 0 1.8em;">0</span> <span id="l2" style="padding: 0 1.8em;">0</span> <span id="l3" style="padding: 0 1.8em;">0</span> <span id="l4" style="padding: 0 1.8em;">0</span> <span id="l5" style="padding: 0 1.8em;">0</span> <span id="l6" style="padding: 0 1.8em;">0</span> <span id="l7" style="padding: 0 1.8em;">0</span> <span id="l8" style="padding: 0 1.8em;">0</span> </div> And the jQuery code is: // setup audiometry sliders $("#eq > span").each(function (e) { // read initial values from markup and remove that var value = parseInt($(this).text()); // var index = $(this).index; <- this didn't work. $(this).empty(); $(this).slider({ value: value, slide: function (event, ui) { //console.log($(this).attr('id')); <- neither did this. //console.log(index); $('#left-values span:first').text(ui.value); } }) }); The problem is that jQuery UI - when creating a slider - replaces the existing HTML with its own markup. This includes any ID values and, for whatever reason, I can't get the index for a given slider to surface either. So I'm running out of ideas.

  • javascript to select text from web page

    - by phil swenson
    I'm trying to write a bookmarklet that grabs any selected text on a web page and sends it to my website. It should (hopefully) work in Chrome, FFX, Safari, and IE. I did a search and found a function, but it doesn't appear to work. Here is the code: <html> <body> <div onClick=getSelText()>Click</div> <div>please select me</div> </body> <script language=javascript> function getSelText(){ var txt = 'nothing'; if (window.getSelection){ txt = "1" + window.getSelection(); } else if (document.getSelection) { txt = "2" + document.getSelection(); } else if (document.selection) { txt = "3" + document.selection.createRange().text; } else return; alert("selected text = " + txt); } </script> </html> when I select the text in the div "please select me" and hit the click div, I just get "selected text = 1" thanks

  • ASP.NET Ajax Error: Sys.WebForms.PageRequestManagerParserErrorException

    - by Phil Bennett
    My website has been giving me intermittent errors when trying to perform any Ajax activities. The message I get is Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' So its obviously some sort of server timeout or the server's just returning back mangled garbage. This generally, unfortunately not always, happens when the site has been idle for a while. Anybody else been able to overcome this? Thanks

  • How do I update the UI during an event using ASP.NET?

    - by Phil Hale
    I'm a bit stuck with a problem. I feel like the solution should be fairly straight forward but I'm completely out of ideas for some reason. Here's the problem. I've got a user control with a couple of buttons. Think of them as 'On' and 'Off'. When either button is clicked an async method is called. If the method is successful an event is fired. Within the event I want to update the enabled property of the two buttons so that only a single button is clickable at any one time. The problem is that any changes I make to the properties are not shown on screen because the postback is already complete. I tried wrapping the buttons in an UpdatePanel but I get an "Update method can only be called on UpdatePanel with ID 'xxxx' before Render' error. I understand why the problem occurs but I can't think of a solution. Help! Ideally what I'd like to do is simply call a method within the event that will update the UI, but I don't know if that's possible.

  • How practical to change MVC app from traditional authentication to cookieless?

    - by Phil.Wheeler
    I have an application written in MVC that uses your regular .Net Forms Authentication. There's nothing particularly new or exciting going on with it. My client has now asked that users be able to log in to the app on the same machine but in different browsers, or different tabs within the same browser. To my mind, he's asking for a scope change to have authentication moved to cookieless instead of its current design. Not having had any experience with doing this in MVC, I'm curious to know before I get started how much hurt I'm in for by trying this. Are there better ways to do it? What should I consider? Any advice appreciated.

  • C# dependency injection - how to you inject a dependency without source?

    - by Phil Harris
    Hi, I am trying to get started with some simple dependency injection using C# and i've run up against an issue that I can't seem to come up with an answer for. I have a class that was written by another department for which I don't have the source in my project. I wanted to inject an object of this type though a constructor using an interface, but of course, i can't change the injected objects implementation to implement the interface to achieve polymorphism when casting the object to the interface type. Every academic example I have ever seen of this technique has the classes uses classes which are declared in the project itself. How would I go about injecting my dependency without the source being available in the project? I hope that makes sense, thanks.

  • Ubuntu: Graphics freeze

    - by Phil
    We have recently updated a java application which runs on an Ubuntu PC, and are now experiencing a graphics problem that we didn't encounter before. The system is running constantly, and randomly maybe twice a month but sometimes within a few days the systems graphics will freeze, and the gnome panels are frozen. Here is an extract from the syslog; Jun 28 05:41:53 swimtag-NM10 kernel: [34802.970021] [drm:i915_hangcheck_elapsed] ERROR Hangcheck timer elapsed...

  • Where can I find a deliberately insecure open source web application?

    - by Phil Laliberte
    As a developer, I've learned that I usually gain a better understanding of best/worst practices through experience. The area of web application security isn't really somewhere where my organization can afford to let developers learn through trial and error. So looking for a hands-on approach to knowledge sharing of best practices in web application security, I was thinking that it would be useful to have an open source application that was deliberately built to be insecure in order to help teach junior developers about application security. Does anyone out there know where to find something like this?

  • Is there a network diagram standard for illustrating web services?

    - by Phil.Wheeler
    I'm putting together a Solution Architecture document for an enhancement we're adding to our site and it occurs to me that I've never formally illustrated a web service call before. Is there a convention for how web service calls are illustrated on your garden-variety network diagram? Can anyone point me to examples or share something on Create.ly (or similar service)?

  • Automatic profiling visual studio 2008

    - by phil
    Is there a way to do automatic profiling in visual studio 2008? I know how the profiling works both from the command line and using the GUI in VS08. What I want to accomplish: After my nightly build I want to complete some profiling (instrumental) to see if some functions (will most likely always be the same) have changed in some negative way (or positive of course).

  • Loading child entities with JPA on Google App Engine

    - by Phil H
    I am not able to get child entities to load once they are persisted on Google App Engine. I am certain that they are saving because I can see them in the datastore. For example if I have the following two entities. public class Parent implements Serializable{ @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") private String key; @OneToMany(cascade=CascadeType.ALL) private List<Child> children = new ArrayList<Child>(); //getters and setters } public class Child implements Serializable{ @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") private String key; private String name; @ManyToOne private Parent parent; //getters and setters } I can save the parent and a child just fine using the following: Parent parent = new Parent(); Child child = new Child(); child.setName("Child Object"); parent.getChildren().add(child); em.persist(parent); However when I try to load the parent and then try to access the children (I know GAE lazy loads) I do not get the child records. //parent already successfully loaded parent.getChildren.size(); // this returns 0 I've looked at tutorial after tutorial and nothing has worked so far. I'm using version 1.3.3.1 of the SDK. I've seen the problem mentioned on various blogs and even the App Engine forums but the answer is always JDO related. Am I doing something wrong or has anyone else had this problem and solved it for JPA?

  • Reverse Engineer a web page

    - by Phil
    Hi, I wish to reverse engineer any web-page into a logical representation of the page. For example, if a web page has a menu, then I want a logical menu structure perhaps in XML. If the webpage has an article, I want a article XML node, if it has a title for the article I want a title XML node. Basically, I want the logical form of the web-page without any of the user interface. This logical model could either be objects in code or XML it doesn't matter, the important part is that it has identified what everything on the page means.

  • Incompatible library creating new project with Aptana

    - by Phil Rice
    I am a ruby and rails newbie, so my abilities to debug this are somewhat limited. I have just added the eclipse plugin which failed, then downloaded the latest aptana studio which also failed. The failure was the same in both cases. The nature of the failure is that when I create a new rails project, I get an error message about an incompatible library version "C:/Ruby193/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5-x86-mswin32-60/lib/http11.so". The project is actually created, along with directories and files. Google searches around this error message have only returned a couple of hits, which were not very helpful I am wondering if this is about 64 bit libraries. My software stack is: Windows 7 home premium 64bit Aptana RadRails, build: 2.0.5.1278709071 Ruby1.9.3 gem 1.8.24 The console shows: "4320" C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': iconv will be deprecated in the future, use String#encode instead.

  • Learn Silverlight or WPF first?

    - by Phil Wright
    It seems that Silverlight/WPF are the long term future for user interface development with .NET. This is great because as I can see the advantage of reusing XAML skills on both the client and web development sides. But looking at WPF/XAML/Silverlight they seem very large technologies and so where is the best place to get start? I would like to hear from anyone who has good knowledge of both and can recommend which is a better starting point and why.
