  • jQuery UI AutoComplete remote json response question

    - by Greg-J
    I was using geonames.org to autocomplete city and state but found it to be far too slow to be reliable. My code is as follows, and does work (wait about 10 seconds to see the autocomplete results) Old (working) code here: http://jsbin.com/umewo3/2/edit Now I am using YQL as they provide a much quicker response. The issue is that I don't seem to understand how to properly map the response. You can see I am sending a well formed request, and getting the response back - but I am somehow not dealing with the response properly. New (broken) code here: http://jsbin.com/aqoke3/2/edit Any and all help appreciated.

  • jQuery Resizable() UI Problem

    - by OneNerd
    In general, resizable() works fine. Here is where I am getting into an issue. I have a div that contains some resizable items that work fine (resizable() applied to them at some point). user can save items for later view (the innerHTML of the div gets saved into a JavaScript array, then div gets cleared so they can do something else) When items get placed back onto div (from array) -- I do a $('#divname').append(arrayname[i]); -- items are no longer resizable (although visually they have the resizable classes/handle on them) Here is what I have tried so far (none of which have worked): After append() line, I re-initialize the resizable -- $('#items').resizable(); After append() line, remove then re-add resizable -- $('#items').resizable('destroy').resizable(); Any help is appreciated - thanks.

  • JQuery UI question, how do you add variables into the dialog box

    $('.openDialog').click(function(event){ var width=$(this).attr('width'); var height=$(this).attr('height'); alert(width + ' ' + height); event.preventDefault(); $("#dialog").dialog({autoOpen: false, modal: true}); $('#dialog').dialog('option', 'width', width); $('#dialog').dialog('open'); $('#dialog p').load('http://pagetoload.com/page.html .content'); }); As you can see above i'm trying to open a dialog box with a passed in parameter of width and height, however when I try and pass in the value of width on this line: $('#dialog').dialog('option', 'width', width); it doesn't work, any ideas why or how to get around that? Thanks

  • Oracle Fusion Applications User Experience Design Patterns: Feeling the Love after Launch

    - by mvaughan
    By Misha Vaughan, Oracle Applications User ExperienceIn the first video by the Oracle Applications User Experience team on the Oracle Partner Network, Vice President Jeremy Ashley said that Oracle is looking to expand the ecosystem of support for Oracle’s applications customers as they begin to assess their investment and adoption of Oracle Fusion Applications. Oracle has made a massive investment to maintain the benefits of the Fusion Applications User Experience. This summer, the Applications User Experience team released the Oracle Fusion Applications user experience design patterns.Design patterns help create consistent experiences across devices.The launch has been very well received:Angelo Santagata, Senior Principal Technologist and Fusion Middleware evangelist for Oracle,  wrote this to the system integrator community: “The web site is the result of many years of Oracle R&D into user interface design for Fusion Applications and features a really cool web app which allows you to visualise the UI components in action.”  Grant Ronald, Director of Product Management, Application Development Framework (ADF) said: “It’s a science I don't understand, but now I don't have to ... Now you can learn from the UX experience of Fusion Applications.”Frank Nimphius, Senior Principal Product Manager, Oracle (ADF) wrote about the launch of the design patterns for the ADF Code Corner, and Jürgen Kress, Senior Manager EMEA Alliances & Channels for Fusion MiddleWare and Service Oriented Architecture, (SOA), shared the news with his Partner Community. Oracle Twitter followers also helped spread the message about the design patterns launch: ?@bex – Brian Huff, founder and Chief Software Architect for Bezzotech, and Oracle ACE Director:“Nifty! The Oracle Fusion UX team just released new ADF design patterns.”@maiko_rocha, Maiko Rocha, Oracle Consulting Solutions Architect and Oracle FMW engineer: “Haven't seen any other vendor offer such comprehensive UX Design Patterns catalog for free!”@zirous_chad, Chad Thompson, Senior Solutions Architect for Zirous, Inc. and ADF Developer:Wow - @ultan and company did a great job with the Fusion UX PatternsWhat is a user experience design pattern?A user experience design pattern is a re-usable, usability tested functional blueprint for a particular user experience.  Some examples are guided processes, shopping carts, and search and search results.  Ultan O’Broin discusses the top design patterns every developer should know.The patterns that were just released are based on thousands of hours of end-user field studies, state-of-the-art user interface assessments, and usability testing.  To be clear, these are functional design patterns, not technical design patterns that developers may be used to working with.  Because we know there is a gap, we are putting together some training that will help close that gap.Who should care?This is an offering targeted primarily at Application Development Framework (ADF) developers. If you are faced with the following questions regarding Fusion Applications, you will want to know and learn more:•    How do I build something that looks like Fusion Applications?•    How do I build a next-generation application?•    How do I extend a Fusion Application and maintain the user experience?•    I don’t want to re-invent the wheel on the user interface, so where do I start?•    I need to build something that will eventually co-exist with Fusion Applications. How do I do that?These questions are relevant to partners with an ADF competency, individual practitioners, or small consultancies with an ADF specialization, and customers who are trying to shift their IT staff over to supporting Fusion Applications.Where you can find out more?OnlineOur Fusion User Experience design patterns maven is Ultan O’Broin. The Oracle Partner Network is helping our team bring this first e-seminar to you in order to go into a more detail on what this means and how to take advantage of it:?

  • Change the Default Number of Rows of Tiles on the Windows 8 UI (Metro) Screen

    - by Lori Kaufman
    By default, Windows 8 automatically sets the number of rows of tiles to fit your screen, depending on your monitor size and resolution. However, you can tell Windows 8 to display a certain number of rows of tiles at all times, despite the screen resolution. To do this, we will make a change to the registry. If you are not already on the Desktop, click the Desktop tile on the Start screen. NOTE: Before making changes to the registry, be sure you back it up. We also recommend creating a restore point you can use to restore your system if something goes wrong. HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows? Java is Insecure and Awful, It’s Time to Disable It, and Here’s How What Are the Windows A: and B: Drives Used For?

  • Creating user UI using Flixel

    - by Jamie Read
    I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives. What I am trying to do is add a Start Screen before actually loading the game. I have a create function that adds all the game elements to the stage: override public function create():void // all game elements { How can I add this pre-load Start Screen? I'm not sure if I have to add in the code to this create function or somewhere else and what code to actually add. Eventually I would also like to add saving, loading, options and upgrades too. So any advice with that would be great. Here is my main game.as: package { import org.flixel.*; public class Game extends FlxGame { private const resolution:FlxPoint = new FlxPoint(640, 480); private const zoom:uint = 2; private const fps:uint = 60; public function Game() { super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom); FlxG.flashFramerate = fps; } } } Thanks.

  • How to elegantly work with a lot of print functions?

    - by user1824372
    I'm working on a Python project that is executed on a terminal (or console) for which I am planning to implement a GUI. I did not major in CS so I really have no idea how to effectively design a terminal GUI such that: the user interface looks good in GUI, it is directed to a certain widget, let's say, a text label, or a bottom bar, or a hide-able frame. Do you have any suggestions? Currently, I am using the print function to provide essential information on STDOUT during execution, so a lot of print calls are distributed here and there in the code. I'm thinking of using macro-like variables such as 'FILE_NOT_EXISTS_MESSAGE' for printing, and all of them and their values would be defined in one file. Is that a standard way to do this? Should I introduce a logging system? In summary, I'm looking for a pattern for handling console output that is effective and adaptable.

  • Add autoFill capabilities to jQuery-UI 1.8.1

    - by rockinthesixstring
    here's what I currently have, unfortunately I cannot seem to figure out how to get autoFill to work with jQuery-UI... It used to work with the straight up Autocomplete.js <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js" type="text/javascript"></script> <script src="http://jquery-ui.googlecode.com/svn/tags/latest/external/jquery.bgiframe-2.1.1.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/i18n/jquery-ui-i18n.min.js" type="text/javascript"></script> <script language="javascript" type="text/javascript"> var thesource = "RegionsAutoComplete.axd?PID=3" $(function () { function log(message) { $("<div/>").text(message).prependTo("#log"); $("#log").attr("scrollTop", 0); } $.expr[':'].textEquals = function (a, i, m) { return $(a).text().match("^" + m[3] + "$"); }; $("#birds").autocomplete({ source: thesource, change: function (event, ui) { //if the value of the textbox does not match a suggestion, clear its value if ($(".ui-autocomplete li:textEquals('" + $(this).val() + "')").size() == 0) { $(this).val(''); } else { log(ui.item ? ("Selected: " + ui.item.value + " aka " + ui.item.id) : "Nothing selected, input was " + this.value); } } }).live('keydown', function (e) { var keyCode = e.keyCode || e.which; //if TAB or RETURN is pressed and the text in the textbox does not match a suggestion, set the value of the textbox to the text of the first suggestion if ((keyCode == 9 || keyCode == 13) && ($(".ui-autocomplete li:textEquals('" + $(this).val() + "')").size() == 0)) { $(this).val($(".ui-autocomplete li:visible:first").text()); } }); }); </script> I've used the answer here to get the mustMatch working, but unfortunately if I "tab" away from the input box, I get the "Nothing selected" response instead of an Value and ID. Does anyone know how to extract the ID out of the autocomplete when you don't actually select the field?

  • What patterns exist for web application development?

    - by DaveDev
    I understand that MVC & MVP are design patterns that are commonly used for web development, as well as ASP.NET WebForms (more of an anti-pattern, really!). What other patterns are used in web application development? I'm not necessarily saying I want to learn/use new patterns just to be different - I do believe there's a lot of value in taking the conventional route - but I think it's good to know what else is out there to be able to properly understand what I'm currently working with. Thanks.

  • design patterns for hierarchical structures

    - by JLBarros
    Anyone knows some design patterns for hierarchical structures? For example, to manage inventory categories, accounting chart of accounts, divisions of human resources, etc.. Thank you very much in advance EDIT: Thanks for your interest. I am looking for a better way of dealing with hierarchical items to which they should apply operations depending on the level of hierarchy. I have been studying the patterns by Martin Fowler, for example Accounting, but I wonder if there are other more generic. The problem is that operations apply to the items must be possible to change even at run time and may depend on other external variables. I thought of a kind of strategy pattern but would like to combine it with the fact that it is a hierarchical scheme. I would appreciate any reference to hierarchical patterns and you'll take care of them in depth.

  • Are there design patterns or generalised approaches for particle simulations?

    - by romeovs
    I'm working on a project (for college) in C++. The goal is to write a program that can more or less simulate a beam of particles flying trough the LHC synchrotron. Not wanting to rush into things, me and my team are thinking about how to implement this and I was wondering if there are general design patterns that are used to solve this kind of problem. The general approach we came up with so far is the following: there is a World that holds all objects you can add objects to this world such as Particle, Dipole and Quadrupole time is cut up into discrete steps, and at each point in time, for each Particle the magnetic and electric forces that each object in the World generates are calculated and summed up (luckily electro-magnetism is linear). each Particle moves accordingly (using a simple estimation approach to solve the differential movement equations) save the Particle positions repeat This seems a good approach but, for instance, it is hard to take into account symmetries that might be present (such as the magnetic field of each Quadrupole) and is this thus suboptimal. To take into account such symmetries as that of the Quadrupole field, it would be much easier to (also) make space discrete and somehow store form of the Quadrupole field somewhere. (Since 2532 or so Quadrupoles are stored this should lead to a massive gain of performance, not having to recalculate each Quadrupole field) So, are there any design patterns? Is the World-approach feasible or is it old-fashioned, bad programming? What about symmetry, how is that generally taken into acount?

  • Book Review: Professional ASP.NET Design Patterns by Scott Millett

    - by Sam Abraham
    In the next few lines, I will be providing a brief review of Wrox’s Professional ASP.NET Design Patterns by Scott Millett. Design patterns have been a hot topic for many years as developers looked to do more with less, re-use as much code as possible by creating common libraries, as well as make their code easier to understand, extend and collaborate on. Scott Millett’s book covered classic and emerging patterns in a practical presentation that demonstrated with thorough examples how to put each pattern to use in the context of multi-tiered ASP.NET applications. The author’s unique approach and content earned him much kudos in the foreword by Scott Hanselman as well as online reviews. The book has 14 chapters of which 5 are dedicated to a comprehensive case study. Patterns covered therein include S.O.L.I.D, Gang of Four (GoF) as well as Martin Fowler’s Patterns of Enterprise Applications. Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group. Best regards, --Sam You can access my reviews of books I recently read: Professional WCF 4.0 Inside Windows Communication Foundation Inside Microsoft SQL Server 2008 series

  • In IE8, jquery-ui's dialog set the height of its contents to zero. How can I fix this?

    - by brahn
    I am using jquery UI's dialog widget to render a modal dialog in my web application. I do this by passing the ID of the desired DOM element into the following function: var setupDialog = function (eltId) { $("#" + eltId).dialog({ autoOpen: false, width: 610, minWidth: 610, height: 450, minHeight: 200, modal: true, resizable: false, draggable: false, }); }; Everything works just fine in Firefox, Safari, and Chrome. However, in IE 8 when the dialog is opened only the div.ui-dialog-titlebar is visible -- the div.ui-dialog-contents are not. The problem seems to be that while in the modern browsers, the div.ui-dialog-contents has a specific height set in its style, i.e. after opening the dialog, the resulting HTML is: <div class="ui-dialog-content ui-widget-content" id="invite-friends-dialog" style="width: auto; min-height: 198px; height: 448px">...</div> while in IE8 the height style attribute is set to zero, and the resulting HTML is: <div class="ui-dialog-content ui-widget-content" id="invite-friends-dialog" style="min-height: 0px; width: auto; height: 0px">...</div> What do I need to do to get the height (and min-height) style attributes set correctly?

    Does anyone know of papers/books/etc. that document patterns for databases? For example, one common rule of thumb is that every table should have a primary key and that the key should be devoid of information content. So I was wondering if anyone had written a book or published papers regarding design patterns for designing relational databases?
