  • atk4 advanced crud?

    - by thindery
    I have the following tables: -- ----------------------------------------------------- -- Table `product` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `product` ( `id` INT NOT NULL AUTO_INCREMENT , `productName` VARCHAR(255) NULL , `s7location` VARCHAR(255) NULL , PRIMARY KEY (`id`) ) ENGINE = InnoDB; -- ----------------------------------------------------- -- Table `pages` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `pages` ( `id` INT NOT NULL AUTO_INCREMENT , `productID` INT NULL , `pageName` VARCHAR(255) NOT NULL , `isBlank` TINYINT(1) NULL , `pageOrder` INT(11) NULL , `s7page` INT(11) NULL , PRIMARY KEY (`id`) , INDEX `productID` (`productID` ASC) , CONSTRAINT `productID` FOREIGN KEY (`productID` ) REFERENCES `product` (`id` ) ON DELETE NO ACTION ON UPDATE NO ACTION) ENGINE = InnoDB; -- ----------------------------------------------------- -- Table `field` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `field` ( `id` INT NOT NULL AUTO_INCREMENT , `pagesID` INT NULL , `fieldName` VARCHAR(255) NOT NULL , `fieldType` VARCHAR(255) NOT NULL , `fieldDefaultValue` VARCHAR(255) NULL , PRIMARY KEY (`id`) , INDEX `id` (`pagesID` ASC) , CONSTRAINT `pagesID` FOREIGN KEY (`pagesID` ) REFERENCES `pages` (`id` ) ON DELETE NO ACTION ON UPDATE NO ACTION) ENGINE = InnoDB; I have gotten CRUD to work on the 'product' table. //addproduct.php class page_addproduct extends Page { function init(){ parent::init(); $crud=$this->add('CRUD')->setModel('Product'); } } This works. but I need to get it so that when a new product is created it basically allows me to add new rows into the pages and field tables. For example, the products in the tables are a print product(like a greeting card) that has multiple pages to render. Page 1 may have 2 text fields that can be customized, page 2 may have 3 text fields, a slider to define text size, and a drop down list to pick a color, and page 3 may have five text fields that can all be customized. All three pages (and all form elements, 12 in this example) are associated with 1 product. So when I create the product, could i add a button to create a page for that product, then within the page i can add a button to add a new form element field? I'm still somewhat new to this, so my db structure may not be ideal. i'd appreciate any suggestions and feedback! Could someone point me toward some information, tutorials, documentation, ideas, suggestions, on how I can implement this?

  • Checking inherited attributes in an 'ancestry' based SQL table

    - by Brendon Muir
    I'm using the ancestry gem to help organise my app's tree structure in the database. It basically writes a childs ancestor information to a special column called 'ancestry'. The ancestry column for a particular child might look like '1/34/87' where the parent of this child is 87, and then 87's parent is 34 and 34's is 1. It seems possible that we could select rows from this table each with a subquery that checks all the ancestors to see if a certain attribute it set. E.g. in my app you can hide an item and its children just by setting the parent element's visibility column to 0. I want to be able to find all the items where none of their ancestors are hidden. I tried converting the slashes to comma's with the REPLACE command but IN required a set of comma separated integers rather than one string with comma separated string numbers. It's funny, because I can do this query in two steps, e.g. retrieve the row, then take its ancestry column, split out the id's and make another query that checks that the id is IN that set of id's and that visibility isn't ever 0 and whala! But joining these into one query seems to be quite a task. Much searching has shown a few answers but none really do what I want. SELECT * FROM t1 WHERE id = 99; 99's ancestry column reads '1/34/87' SELECT * FROM t1 WHERE visibility = 0 AND id IN (1,34,87); kind of backwards, but if this returns no rows then the item is visible. Has anyone come across this before and come up with a solution. I don't really want to go the stored procedure route. It's for a rails app.

  • What's the standard convention for creating a new NSArray from an existing NSArray?

    - by Prairiedogg
    Let's say I have an NSArray of NSDictionaries that is 10 elements long. I want to create a second NSArray with the values for a single key on each dictionary. The best way I can figure to do this is: NSMutableArray *nameArray = [[NSMutableArray alloc] initWithCapacity:[array count]]; for (NSDictionary *p in array) { [nameArray addObject:[p objectForKey:@"name"]]; } self.my_new_array = array; [array release]; [nameArray release]; } But in theory, I should be able to get away with not using a mutable array and using a counter in conjunction with [nameArray addObjectAtIndex:count], because the new list should be exactly as long as the old list. Please note that I am NOT trying to filter for a subset of the original array, but make a new array with exactly the same number of elements, just with values dredged up from the some arbitrary attribute of each element in the array. In python one could solve this problem like this: new_list = [p['name'] for p in old_list] or if you were a masochist, like this: new_list = map(lambda p: p['name'], old_list) Having to be slightly more explicit in objective-c makes me wonder if there is an accepted common way of handling these situations.

  • jQuery: preventDefault() not working on input/click events?

    - by Jason
    I want to disable the default contextMenu when a user right-clicks on an input field so that I can show a custom contextMenu. Generally speaking, its pretty easy to disable the right-click menu by doing something like: $([whatever]).bind("click", function(e) { e.preventDefault(); }); And in fact, I can do this on just about every element EXCEPT for input fields in FF - anyone know why or could point me towards some documentation? Here is the relevant code I am working with, thanks guys. HTML: <script type="text/javascript"> var r = new RightClickTool(); </script> <div id="main"> <input type="text" class="listen rightClick" value="0" /> </div> JS: function RightClickTool(){ var _this = this; var _items = ".rightClick"; $(document).ready(function() { _this.init(); }); this.init = function() { _this.setListeners(); } this.setListeners = function() { $(_items).click(function(e) { var webKit = !$.browser.msie && e.button == 0; var ie = $.browser.msie && e.button == 1; if(webKit||ie) { // Left mouse...do something() } else if(e.button == 2) { e.preventDefault(); // Right mouse...do something else(); } }); } } // Ends Class

  • Serializing a DataType="time" field using XmlSerializer

    - by CraftyFella
    Hi, I'm getting an odd result when serializing a DateTime field using XmlSerializer. I have the following class: public class RecordExample { [XmlElement("TheTime", DataType = "time")] public DateTime TheTime { get; set; } [XmlElement("TheDate", DataType = "date")] public DateTime TheDate { get; set; } public static bool Serialize(Stream stream, object obj, Type objType, Encoding encoding) { try { using (var writer = XmlWriter.Create(stream, new XmlWriterSettings { Encoding = encoding })) { var xmlSerializer = new XmlSerializer(objType); if (writer != null) xmlSerializer.Serialize(writer, obj); } return true; } catch (Exception) { return false; } } } When i call the use the XmlSerializer with the following testing code: var obj = new RecordExample {TheDate = DateTime.Now.Date, TheTime = new DateTime(0001, 1, 1, 12, 00, 00)}; var ms = new MemoryStream(); RecordExample.Serialize(ms, obj, typeof (RecordExample), Encoding.UTF8); txtSource2.Text = Encoding.UTF8.GetString(ms.ToArray()); I get some strange results, here's the xml that is produced: <?xml version="1.0" encoding="utf-8"?> <RecordExample xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <TheTime>12:00:00.0000000+00:00</TheTime> <TheDate>2010-03-08</TheDate> </RecordExample> Any idea's how i can get the "TheTime" element to contain a time which looks more like this: <TheTime>12:00:00.0Z</TheTime> ...as that's what i was expecting? Thanks Dave

  • Android app after update: crashes on Motorola Cliq with weird stacktrace

    - by sandis
    So after updating my app on the market I am getting reports from motorola cliq-users that my app crashes on start. The stacktrace is below, and is not very helpful since it does not go trough my app!

  • PHP - Best practice to retain form values across postback

    - by Adam
    Hello, Complete PHP novice here, almost all my previous work was in ASP.NET. I am now working on a PHP project, and the first rock I have stumbled upon is retaining values across postback. For the most simple yet still realistic example, i have 10 dropdowns. They are not even databound yet, as that is my next step. They are simple dropdowns. I have my entire page inclosed in a tag. the onclick() event for each dropdown, calls a javascript function that will populate the corrosponding dropdowns hidden element, with the dropdowns selected value. Then, upon page reload, if that hidden value is not empty, i set the selected option = that of my hidden. This works great for a single postback. However, when another dropdown is changed, the original 1'st dropdown loses its value, due to its corrosponding hidden value losing its value as well! This draws me to look into using querystring, or sessions, or... some other idea. Could someone point me in the right direction, as to which option is the best in my situation? I am a PHP novice, however I am being required to do some pretty intense stuff for my skill level, so I need something flexable and preferribly somewhat easy to use. Thanks! -----edit----- A little more clarification on my question :) When i say 'PostBack' I am referring to the page/form being submitted. The control is passed back to the server, and the HTML/PHP code is executed again. As for the dropdowns & hiddens, the reason I used hidden variables to retain the "selected value" or "selected index", is so that when the page is submitted, I am able to redraw the dropdown with the previous selection, instead of defaulting back to the first index. When I use the $_POST[] command, I am unable to retrieve the dropdown by name, but I am able to retrieve the hidden value by name. This is why upon dropdown-changed event, I call javascript which sets the selected value from the dropdown into its corrosponding hidden.

  • Generate and merge data with python multiprocessing

    - by Bobby
    I have a list of starting data. I want to apply a function to the starting data that creates a few pieces of new data for each element in the starting data. Some pieces of the new data are the same and I want to remove them. The sequential version is essentially: def create_new_data_for(datum): """make a list of new data from some old datum""" return [datum.modified_copy(k) for k in datum.k_list] data = [some list of data] #some data to start with #generate a list of new data from the old data, we'll reduce it next newdata = [] for d in data: newdata.extend(create_new_data_for(d)) #now reduce the data under ".matches(other)" reduced = [] for d in newdata: for seen in reduced: if d.matches(seen): break #so we haven't seen anything like d yet seen.append(d) #now reduced is finished and is what we want! I want to speed this up with multiprocessing. I was thinking that I could use a multiprocessing.Queue for the generation. Each process would just put the stuff it creates on, and when the processes are reducing the data, they can just get the data from the Queue. But I'm not sure how to have the different process loop over reduced and modify it without any race conditions or other issues. What is the best way to do this safely? or is there a different way to accomplish this goal better?

  • Does Internet Explorer 7 have a CSS parsing issue with the "background-image" property?

    - by user312003
    Having CSS layout issues with Internet Explorer 7 (big surprise). Upon using the Developer Tools to inspect the CSS, I discovered that some properties defined in the stylesheet are not appearing in the parsed CSS structure... THEN I saw THIS being shown as the parsed value for the background-image property: background-image : url(/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg); WIDTH: 1200px; pretty much obliterating the width that was defined property. The actual code in the CSS file for this element: div#header { width: 1200px; height: 100px; margin-left: auto; margin-right: auto; background-image: url('/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg'); background-repeat: no-repeat; } If anyone could offer any insight, or provide a link describing this problem (and maybe a workaround...) I would be very appreciative. Also, I am only interested in this from a parsing of the stylesheet and CSS syntax perspective. I am not concerned with rendering and display issues at the moment; I simply want to get IE 7 (and I have a feeling IE 6 will have similar issues) to recognize and parse ALL of the CSS properties that have been defined in the stylesheet. Thanks in advance guys!

  • Authorization and Jquery dialog problem.

    - by bbrepols
    Hi, I have a little problem with a Jquery dialog for an action that requires a role. In my example, the user can click on a delete button and must confirm the action. In my controller, the Delete action requires a role, if the user is in the required role, the object is deleted. The problem: How to alert the user if * the element was deleted (redirect to the Index view) * there was an error (alert with the message) * he doesn't have the rights to delete (alert with the message) Before using the authorize filter, the delete action returned a JSON with a Boolean that indicates if there was an error, an URL to redirect on success and a message to alert on error. As I can't return a JSON from my filter, I created an other method with the authorize filter that returns a partial view with the confirm content. If the user doesn't have the rights, the filter returns a partial view with an unauthorized exception content. The problem: How to distinct which partial view was returned. When I create the dialog, I need to know for the buttons function. Thanks!

  • Use jQuery to find and add an image tooltip

    - by lund.mikkel
    Hey people Okay, what I'm trying to accomplish is a simple tool tip that, when you hover over the name of a color, shows a little image of that color. The html markup looks like this: <label class="colorPicker"> <input type="radio" checked="" id="20" value="20" name="id[2]"> <img width="16" height="16" title=" DinoBlack Mat " alt="DinoBlack Mat" src="images/attributes/color/dinoblack_mat.jpg">DinoBlack Mat </label> <label class="colorPicker"> <input type="radio" id="874" value="874" name="id[2]"> <img width="16" height="16" title="XrayBlue shiny" alt="XrayBlue shiny" src="images/attributes/color/xrayblue_shiny.jpg">XrayBlue shiny </label> I'm using the jQuery plugin "Tooltip" and I've added following to my main js-file: $('.colorPicker').tooltip({ track: true, delay: 0, showURL: false, fade: 250, bodyHandler: function() { return $("<img/>").attr("src", [THE SOURCE FOR THE IMAGE]); } }); The idea is simply that the image should be hidden by default. But when you hover over the text the little thumbnail shows up and makes it easy to recognize the color. The problem is I haven't got a clue how to get the src for the thumbnail. I don't know how to extract the src from the img inside the selected element. I've tried various combinations using the this keyword, but nothing seemed to work. I've also tried to add the src path as a rel attribute to the label, but also without any success. Should be needless to say I also control the PHP-output... I really hope you can help me. I've search the web for days without any luck. I'm getting desperate :D /Mikkel Lund

  • JS/CSS include section replacement, Debug vs Release

    - by Bayard Randel
    I'd be interested to hear how people handle conditional markup, specifically in their masterpages between release and debug builds. The particular scenario this is applicable to is handling concatenated js and css files. I'm currently using the .Net port of YUI compress to produce a single site.css and site.js from a large collection of separate files. One thought that occurred to me was to place the js and css include section in a user control or collection of panels and conditionally display the <link> and <script> markup based on the Debug or Release state of the assembly. Something along the lines of: #if DEBUG pnlDebugIncludes.visible = true #else pnlReleaseIncludes.visible = true #endif The panel is really not very nice semantically - wrapping <script> tags in a <div> is a bit gross; there must be a better approach. I would also think that a block level element like a <div> within <head> would be invalid html. Another idea was this could possibly be handled using web.config section replacements, but I'm not sure how I would go about doing that.

  • Java: Altering UI fonts (Nimbus) doesn't work!

    - by ivan_ivanovich_ivanoff
    Hello! I'm referring to this Nimbus reference. I tried to set global Font to be slightly larger: UIManager.put("defaultFont", new Font(Font.SANS_SERIF, 0, 16)); ...works only for the menu but nothing else (buttons, labels). I tried to change labels and buttons fonts with UIManager.put("Button.font", new Font(Font.SANS_SERIF, 0, 16)); UIManager.put("Label.font", new Font(Font.SANS_SERIF, 0, 16)); but the font remains. The only thing that worked for me was deriving a font: someButton.setFont(someButton.getFont().deriveFont(16f)); But this is not an option, since this must be done for each element manually. Note, that deriving a font for UIManager doesn't work either: UIManager.put("Label.font", UIManager.getFont("Label.font").deriveFont(16f)); I tested everything under Linux and Windows: same behavior. I just can't understand how an API can be so messy. If a method is called setFont(..) then I expect it to set the font. If this method fails to set the font in any thinkable circumstances, then it should be deprecated. EDIT: The problem not only applies to Nimbus, but also to the default LAF.

  • Dynamic columns/rows

    - by Fuego DeBassi
    Wondering--does anyone know of any good articles explaining the CSS technique allowing multiple instances of a class to flow down the page relative to the items above it. Not explaining it that well. Veerle' Pierter's does it on this page: http://veerle.duoh.com/belgiangraphicdesign Although I'm not sure I want to use a technique like her's that requires entering of the height per element via her EE installation. I made a little graphic of what I am trying to acheive; http://cl.ly/71163510ce9d294f9f33 The key is I need a robust technique for doing it. Something where the markup could be as simple as; <div class="box"> Number 1 </div> <div class="box"> Number 2 </div> <div class="box"> Number 3 </div> <div class="box"> Number 4 </div> <div class="box"> Number 5 </div> ... Would love any pointers in the right direction.

  • Counting elements and reading attributes with .net2.0 ?

    - by Prix
    I have an application that is on .net 2.0 and I am having some difficult with it as I am more use to linq. The xml file look like this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <updates> <files> <file url="files/filename.ext" checksum="06B9EEA618EEFF53D0E9B97C33C4D3DE3492E086" folder="bin" system="0" size="40448" /> <file url="files/filename.ext" checksum="CA8078D1FDCBD589D3769D293014154B8854D6A9" folder="" system="0" size="216" /> <file url="files/filename.ext" checksum="CA8078D1FDCBD589D3769D293014154B8854D6A9" folder="" system="0" size="216" /> </files> </updates> The file is downloaded and readed on the fly: XmlDocument readXML = new XmlDocument(); readXML.LoadXml(xmlData); Initially i was thinking it would go with something like this: XmlElement root = doc.DocumentElement; XmlNodeList nodes = root.SelectNodes("//files"); foreach (XmlNode node in nodes) { ... im reading it ... } But before reading them I need to know how many they are to use on my progress bar and I am also clueless on how to grab the attribute of the file element in this case. How could I count how many "file" ELEMENTS I have (count them before entering the foreach ofc) and read their attributes ? I need the count because it will be used to update the progress bar. Overall it is not reading my xml very well.

  • jQuery Accordion: IE animation issues

    - by Nathan Long
    Update I am making this a community wiki, for three reasons: I don't feel like I got a definitive answer, but I have long since stopped needing an answer, because I rolled my own accordion function this question gets tons of views, so clearly lots of people are still interested So if anybody wants to change/clarify this question and make it a definitive guide, be my guest. I'm working on a page using jQuery's accordion UI element. I modeled my HTML on that example, except that inside the <li> elements, I have some unordered lists of links. Like this: $(document).ready(function() { $(".ui-accordion-container").accordion( {active: "a.default", alwaysOpen: true, autoHeight: false} ); }); <ul class="ui-accordion-container"> <li> <!-- Start accordion section --> <a href='#' class="accordion-label">A Group of Links</a> <ul class="linklist"> <li><a href="http://example.com">Example Link</a></li> <li><a href="http://example.com">Example Link</a></li> </ul> <!--and of course there's another group --> Problem: IE Animation stinks Although IE7 animates the documentation's example accordion menu just fine, it has problems with mine. Specifically, one accordion menu on the page moves jerkily and has flashes of content. I know that it's not a CSS issue because the same thing happens if I don't include my CSS files. The other accordion menu on the page opens the first section you click and, after that, won't open any of them. Both of these problems are IE-specific, and both go away if I use the option animated: false. But I'd like to keep the default slide animation, since it helps the user understand what the menu is doing. Is there another way?

  • Listen to double click not click

    - by Mohsen
    I'm just wondering why click event happening when I dbclick an element? I have this code:(JSBIN) HTML <p id="hello">Hello World</p> JavaScript document.getElementById('hello').addEventListener('click', function(e){ e.preventDefault(); this.style.background = 'red'; }, false); document.getElementById('hello').addEventListener('dbclick', function(){ this.style.background = 'yellow'; }, false); It should do different things for click and double click, but it seems when you double click on the p it catch click event in advance and ignore double click. I tried preventDefault the click event too. How can I listen to just dbclick? UPDATE I had a typo in my code. dbclick is wrong. It's dblclick. Anyway the problem still exist. When user double clicks the click event happens. This is updated code that prove it:(JSBin) document.getElementById('hello').addEventListener('click', function(e){ e.preventDefault(); this.style.background = 'red'; this.innerText = "Hello World clicked"; }, false); document.getElementById('hello').addEventListener('dblclick', function(){ this.style.background = 'green'; }, false);

  • Is there a version of the removeElement function in Go for the vector package like Java has in its V

    - by Brian T Hannan
    I am porting over some Java code into Google's Go language and I converting all code except I am stuck on just one part after an amazingly smooth port.

  • Processing XML form input in ASP

    I'm maintaining a legacy application which consists of some ASP.Net pages with c# code behinds and some asp pages. I need to change the way the application accepts it's input from reading a set of parameters from some form fields to reading in one form field which contains contains some XML and parsing to get the parameters out. I've written a C# class that takes an The NameValueCollection from the C# HttpRequest's Form Element. Like so NameValueCollection form = Request.Form; Dictionary<string, string> fieldDictionary = RequestDataExtractor.BuildFieldDictionary(form); The code in the class looks for a particular parameter and if it's there processes the XML and outputs a Dictionary, if its not there it just cycles through the Form parameters and puts them all into the dictionary (Allowing the old method to still work) How would I do this in ASP? Can I use my same class, or a modified version of it? or do I have to write some new code to get this working? If I have to write ASP code Whats the best way to process the XML in ASP? Sorry if this seems like a stupid question but I know next to nothing about ASP and VB.

  • jQuery multiple themes on one page

    - by lloydphillips
    This is driving me NUTS! I've followed the post here which just doesn't seem to be working: http://www.filamentgroup.com/lab/using_multiple_jquery_ui_themes_on_a_single_page/ I have a base theme, for examples sake it's the Smoothness theme from the jQuery UI gallery. Then I have a 'red' theme which basically colours the buttons red. Here is the theme I created. So I go to download my theme. Choose Advanced settings, set the scope to 'red' and my theme folder name to 'red' and download. First of all I'm not entirely 100% sure which folder I'm to copy over to my project is it the 'development-bundle\themes' folder (which contains my red folder) or the '\css\red' folder? I've tried both. The post above seems to suggest if I copy my themes folder and link to my theme in the css it'll work when I add a class of 'red' to a wrapper div or element. So I've linked the themes like so in my file: <link type="text/css" href="themes/base/jquery.ui.all.css" rel="stylesheet" /> <link type="text/css" href="themes/red/jquery.ui.all.css" rel="stylesheet" /> The base theme loads and works all honkey doorey but the red theme doesn't. I've got a button styled like so: <input type="submit" id="btn" value="A submit button" class="red" /> I've also tried: <div class="red"> <input type="submit" id="btn" value="A submit button" /> </div> Neither work. When I remove the 'themes/base/jquery.ui.all.css' css file link the button's aren't styled at all. Crazy! I'm pulling my hair out. Where am I going wrong? Surely they should just make it easy enough to download JUST the theme folder and reference the ui.all file.

  • Getting size of a specific byte array from an array of pointers to bytes

    - by Pat James
    In the following example c code, used in an Arduino project, I am looking for the ability to get the size of a specific byte array within an array of pointers to bytes, for example void setup() { Serial.begin(9600); // for debugging byte zero[] = {8, 169, 8, 128, 2,171,145,155,141,177,187,187,2,152,2,8,134,199}; byte one[] = {8, 179, 138, 138, 177 ,2,146, 8, 134, 8, 194,2,1,14,199,7, 145, 8,131, 8,158,8,187,187,191}; byte two[] = {29,7,1,8, 169, 8, 128, 2,171,145,155,141,177,187,187,2,152,2,8,134,199, 2, 2, 8, 179, 138, 138, 177 ,2,146, 8, 134, 8, 194,2,1,14,199,7, 145, 8,131, 8,158,8,187,187,191}; byte* numbers[3] = {zero, one, two }; function(numbers[1], sizeof(numbers[1])/sizeof(byte)); //doesn't work as desired, always passes 2 as the length function(numbers[1], 25); //this works } void loop() { } void function( byte arr[], int len ) { Serial.print("length: "); Serial.println(len); for (int i=0; i<len; i++){ Serial.print("array element "); Serial.print(i); Serial.print(" has value "); Serial.println((int)arr[i]); } } In this code, I understand that sizeof(numbers1)/sizeof(byte)) doesn't work because numbers1 is a pointer and not the byte array value. Is there a way in this example that I can, at runtime, get at the length of a specific (runtime-determined) byte array within an array of pointers to bytes? Understand that I am limited to developing in c (or assembly) for an Arduino environment. Also open to other suggestions rather than the array of pointers to bytes. The overall objective is to organize lists of bytes which can be retrieved, with length, at runtime.

  • Where can I find a professional image gallery built on a javascript framework?

    - by user278457
    I'm looking to find a galleria replacement, hopefully using jQuery but other javascript frameworks such as prototype or mootools are fine too. I used galleria a while back, and I need a similar product now. Unfortunately, the devkick.com domain seems to have disappeared in the meantime and I'm wary of using products that aren't actively maintained. I'm willing to pay up to $50 per site for licensing costs, if the product meets my needs. I'm specifically looking for a gallery with the following features: Every image in the gallery preloads asap, not as the user clicks "next" Minimalist default css to keep my subsequent styling headaches down, preferably a "darkroom" style by default, much as galleria looks Each element that constructs the image gallery should be simple and logical to reference with CSS As easy to install as adding a css class to a single unordered list No dependencies other than the core jQuery/other library, including "easing" and other effects must be optional Works on browsers back to IE6, Firefox 3, Safari (and iPhone), Chrome, Opera Has a javascript API that lets me trigger callback functions on common events such as "user clicks next" or "image loads" degrades gracefully without javascript, either displays images as a list, or just displays the first image in the list bonus: The gallery can display other content, such as video or external sites, like the modal boxes at shadowbox-js.com well documented minimal bandwidth requirement - .js file should be ~10kb minified bonus: The gallery source is hosted on a reliable CDN like google's bonus: Thumbnails for images do not appear until the main image has loaded bonus: includes ability to set parameters with JSON to change common behaviours, such as slide/fade transitions or automatic image switch every X seconds

  • Possible defect with jQuery ':checked' selector (finding checked checkbox when there are none)

    - by Mphammad Ashour
    Found a strange thing. The following code is supposed to set a default value for a UI element based on whether one of a group of checkboxes (all having attribute name="privacy") is checked (in say, a form postback). If there is no value in the HTML sent by the server (the form is not a postback), the default value should be firstMenuItemKey. Otherwise, it should be the one checked in the underlying HTML. However, while this works on the first call to the URL that includes the form, a refresh of the page will set the value of defaultPrivacyValue to one of the privacy checkboxes'. I've checked that the server isn't checking the checkbox before the script runs (it's not). I've also checked whether somewhere else in the script is checking the checkbox (it's not). var defaultPrivacyValue = firstMenuItemKey; $('input[name=privacy]:checked').each(function() { defaultPrivacyValue = $(this).next().find('.name').text(); }); selectMenuItem(defaultPrivacyValue); When I chaged the selector to 'input[name=privacy][checked=checked]' it worked as expected. Is this a defect in the jQuery implementation of DOM retrieval based on the ':checked' selector???? I'm using jQuery 1.4.2. Thanks for any help you can give.

  • OpenCL - incremental summation during compute

    - by user1721997
    I'm absolutelly novice in OpenCL programming. For my app. (molecular simulaton) I wrote a kernel for calculate intermolecular potential of lennard-jones liquid. In this kernel I need to compute cumulative value of the potential of all particles with one: __kernel void Molsim(__global const float* inmatrix, __global float* fi, const int c, const float r1, const float r2, const float r3, const float rc, const float epsilon, const float sigma, const float h1, const float h23) { float fi0; float fi1; float d; unsigned int i = get_global_id(0); //number of particles (typically 2000) if(c!=i) { // potential before particle movement d=sqrt(pow((0.5*h1-fabs(0.5*h1-fabs(inmatrix[c*3]-inmatrix[i*3]))),2.0)+pow((0.5*h23-fabs(0.5*h23-fabs(inmatrix[c*3+1]-inmatrix[i*3+1]))),2.0)+pow((0.5*h23-fabs(0.5*h23-fabs(inmatrix[c*3+2]-inmatrix[i*3+2]))),2.0)); if(d<rc) { fi0=4.0*epsilon*(pow(sigma/d,12.0)-pow(sigma/d,6.0)); } else { fi0=0; } // potential after particle movement d=sqrt(pow((0.5*h1-fabs(0.5*h1-fabs(r1-inmatrix[i*3]))),2.0)+pow((0.5*h23-fabs(0.5*h23-fabs(r2-inmatrix[i*3+1]))),2.0)+pow((0.5*h23-fabs(0.5*h23-fabs(r3-inmatrix[i*3+2]))),2.0)); if(d<rc) { fi1=4.0*epsilon*(pow(sigma/d,12.0)-pow(sigma/d,6.0)); } else { fi1=0; } // cumulative difference of potentials fi[0]+=fi1-fi0; } } My problem is in the line: fi[0]+=fi1-fi0;. In the one-element vector fi[0] are wrong results. I read something about sum reduction, but I do not know how to do it during the calculation. Exist any simple solution of my problem?
