  • jQuery - making sure content is loaded before it's faded in?

    - by Kenny Bones
    Hi, Nick Craver really helped me out alot with this code in this thread http://stackoverflow.com/questions/2743443/jquery-can-someone-help-stitching-jquery-code-with-ajaxcomplete/2743791#2743791 And it is working. But I notice that there's a small delay after I've clicked a link and before the content is actually loaded. It's not very intense content that's loaded either so I think it's got something to do with the order which things happen in the script. The original code looks like this: $('.dynload').live('click', function(){ var toLoad = $(this).attr('href')+' #content'; $('#content').fadeOut('fast',loadContent); $('#ajaxloader').fadeIn('normal'); function loadContent() { $('#content').load(toLoad,'',showNewContent()) } function showNewContent() { $('#content').fadeIn('fast',hideLoader()); //Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); } function hideLoader() { $('#ajaxloader').fadeOut('normal'); } return false; }); The new code looks like this: $(function() { $('.dynload').live('click', function(){ $('#ajaxloader').fadeIn('fast'); $('#ajaxloaderfridge').fadeIn('fast'); var href = this.href + ' #content'; $('#content').fadeOut('fast',function() { $(this).load(href,'', function(data) { createMenus(); $('#ajaxloader').fadeOut('fast'); $('#ajaxloaderfridge').fadeOut('fast'); $('#content').fadeIn('fast'); Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); }); }); return false; }); }); $(createMenus); function createMenus() { $('#kontrollpanel .slidepanels').kwicks({ min : 42, spacing : 3, isVertical : true, sticky : true, event : 'click' }); } In the original code, #content is faded out, then the function "loadContent" is started. Which is basically what is happening in the new script as well isn't it? And when I was using the old code, the content just faded out and faded in really fast and smooth and with no small pause delay before the content arrived.

  • Some help needed with a SQL query

    - by Psyche
    Hello, I need some help with a MySQL query. I have two tables, one with offers and one with statuses. An offer can has one or more statuses. What I would like to do is get all the offers and their latest status. For each status there's a table field named 'added' which can be used for sorting. I know this can be easily done with two queries, but I need to make it with only one because I also have to apply some filters later in the project. Here's my setup: CREATE TABLE `test`.`offers` ( `id` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY , `client` TEXT NOT NULL , `products` TEXT NOT NULL , `contact` TEXT NOT NULL ) ENGINE = MYISAM ; CREATE TABLE `statuses` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `offer_id` int(11) NOT NULL, `options` text NOT NULL, `deadline` date NOT NULL, `added` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1

  • Servlets: forwarding to a resource in a different webapp

    - by skaffman
    I'm trying to construct a java web app along modular principles, with some common resources (JSPs, mainly) in one WAR, and some custom resources in another. This means JSPs scattered across different WARs. Now JavaEE frowns upon this sort of shenanigans, and wants you to put everything in one place. My current workaround to this is to have an Eclipse-triggered Ant script which copies the content of one WAR into the other, but this is not a pleasant solution (it's fragile and too IDE-dependent). Ideally, what I'd like to be able to do is for a servlet to forward to a JSP located in a different WAR to one in which it is itself deployed. This would allow greater freedom in how I assemble my WARs. However, the RequestDispatcher does not seem to support such things. Another possibility is to use <c:import>, which does allow resources to be imported from a different WAR (with some caveats). This would probably allow me to have a "hook" JSP in one WAR, which then drags in the required JSP from another. This is a bit clunky, though, and the fact that <c:import> permits it shows that the underlying servlet API does also. But how do I access that functionality via the RequestDispatcher in a servlet?

  • Runtime Error: "Out of Memory" From Excel Macro

    - by user356180
    I have one macro, which is called when a cell change occurs. This macro selects images, deletes them, and inserts another image depending on a cell value using the following code. I have the same code for two sheets. Private Sub Worksheet_SelectionChange(ByVal Target As Range) ActiveSheet.Shapes.SelectAll Selection.Delete 'insert image code here. End Sub In one sheet, it's working perfectly fine and deletes all images, while in the other sheet, it gives me the runtime error "Out of Memory" and highlights the following line: ActiveSheet.Shapes.SelectAll Can anyone tell me why this is happening? It works perfectly fine in one and not in the other. One other thing I want to tell you is it was working fine when I gave this Excel macro to my client; both sheets were working fine. Suddenly after 2 days, he started getting the error on one sheet on which he was working a lot. I don't know why this is happening. Can anyone tell me what's the reason for this and how I can solve it?

  • rails + paperclip: Is a generic "Attachment" model a good idea?

    - by egarcia
    On my application I've several things with attachments on them, using paperclip. Clients have one logo. Stores can have one or more pictures. These pictures, in addition, can have other information such as the date in which they were taken. Products can have one or more pictures of them, categorized (from the font, from the back, etc). For now, each one of my Models has its own "paperclip-fields" (Client has_attached_file) or has_many models that have attached files (Store has_many StorePictures, Product has_many ProductPictures) My client has also told me that in the future we might be adding more attachments to the system (i.e. pdf documents for the clients to download). My application has a rather complex authorization system implemented with declarative_authorization. One can not, for example, download pictures from a product he's not allowed to 'see'. I'm considering re-factoring my code so I can have a generic "Attachment" model. So any model can has_many :attachments. With this context, does it sound like a good idea? Or should I continue making Foos and FooPictures?

  • Rails model to represent multiple fields

    - by Tristan O'Neil
    I'm developing a rails project where I have one data model with multiple fields that are collection selects. I'd like to create another model to represent all of these collection select fields. So, for instance, my main data model has three collection select fields -- one for county, one for category, and one for classification. I could separate these into three separate data models, but that seems redundant since they all share the same characteristics. They have a type and a value, like a county is a county and it has a value of let's say Sonoma, just as category has a type of category and a value of let's say Winery. If you've ever used Drupal, I'm basically looking for the behavior of the taxonomy functionality. So you see my dilemma: I need to separate these fields into three separate fields but they have very similar data structures. Any suggestions would be greatly appreciated.

  • jQuery: Preventing an event from being attached more than once?

    - by Evan Carroll
    Essentially, I have an element FOO that I want when clicked to attach a click event to a completely separate set of elements BAR, so that when they're clicked they can revert FOO to its previous content. I only want this event attached once. When FOO is clicked, its content is cached away in $back_up, and a trigger is added on the BAR set so that when clicked they can revert FOO back to its previous state. Is there a clever way to do this? Like to only .bind() if the event doesn't already exist? $('<div class="noprint little check" />').click( function () { var $warranty_explaination = $(this).closest('.page').children('.warranty_explaination'); var $back_up = $warranty_explaination.clone(true); $(this).closest('.page').find('.warranties .check:not(.noprint)').click( function () { /* This is the code I don't want to fire more than once */ /*, I just want it to be set to whatever is in the $back_up */ alert('reset'); $warranty_explaination.replaceWith( $back_up ) } ); $warranty_explaination.html('asdf') } ) Currently, the best way I can think to do this is to attach a class, and select where that class doesn't exist.

  • why i change the alpha value of UIImageView but no effect?

    - by chancy
    I am working on a reader app. when you read one magazine, it will display first five pages and download the rest pages one by one. there is a scrollview to view the thumbnail image of pages. At the beginning, if the page needs downloading, the corresponding thumbnail view's alpha value is set to 0.5. when the page is downloaded, i will update the thumbnail view's value to 1.0. I use one operation to download the page, and when one is downloaded i use delegate to set thumbnail view's alpha. But when i update thumbnail view's alpha value, it still the same as the beginning. it seems the alpha has no effect. I wonder is there anything wrong with my code? some snippets are as follows: In the PageViewController.m - (void)downloadPages { DownloadOperation *op = [[DownloadOperation alloc] initWithMagazine:magazine]; op.delegate = self; [[(AppDelegate *)[[UIApplication sharedApplication] delegate] sharedOperationQueue] addOperation:op]; } - (void)downloadOperation:(DownloadOperation *)operation finishedAtIndex:(NSUInteger)index { if (thumbScrollView){ [thumbScrollView viewWithTag:THUMBVIEW_OFFSET+index].alpha = 1.0; } } In DownloadOperation.m - (void)main { // ... NSUInteger index = 0; for (Page *page in mMagazine.pages) { if (/*page doesn't exist*/){ // download the page; if ([delegate respondsToSelector:@selector(downloadOperation:finishedAtIndex:)]) { [delegate downloadOperation:self finishedAtIndex:index]; } } index++; } }

  • Visual Basic: Newbie questions.

    - by Omega
    Hello there. I am starting to learn visual basic. So far, it is quite simple and easy to use. I am liking it! Anyway, I want to make applications a little bit more complex. So far I have done very silly things. I would appreciate if you could help me with these: How do I open a new window (form)? Maybe I click a button on my main form and another form pops up. How do I "deactivate" the main form while the new form is running? (if I try to click the main form, an error sound plays) So my second form has a text field and a "OK" button. If I click it, the second form closes activating the main form again. I want to "pass" the text in the text field from the second form to the first one. How do I do that? Thank you, I am enjoying this new programming environment (didn't use Visual Studio much before)

  • Help with validation rules

    - by George Garman
    I am trying to figure out how to validate a section of a form using php. If at least one of value 1-5 is checked, then at least one of value A-E must be checked. Value's A-E cannot be allowed without at least one of 1-5 being checked. Multiple values in each section can be selected, as long as there is at least one value in each section checked. I have tried individual IF statements and arrays without success. Does anyone have any suggestions or examples? I am missing something and I am certain it is pretty obvious, right in my face.

  • a good Java guide

    - by Lo'oris
    Do you know a good guide for Java, such as "dive into python" for python? If I searched google I expect I would find tons of random guides, but trying them all until I found a good one could take ages... that's why I am asking: do you already know one in particular? one you KNOW is good? I already know C, PHP and a bit of Python, if that matters.

  • Creating a Simple C# Wrapper to clean up code

    - by Tangopop
    I have this code: public void Contacts(string domainToBeTested, string[] browserList, string timeOut, int numberOfBrowsers) { verificationErrors = new StringBuilder(); for (int i = 0; i < numberOfBrowsers; i++) { ISelenium selenium = new DefaultSelenium("LMTS10", 4444, browserList[i], domainToBeTested); try { selenium.Start(); selenium.Open(domainToBeTested); selenium.Click("link=Email"); Assert.IsTrue(selenium.IsElementPresent("//div[@id='tabs-2']/p/a/strong")); selenium.Click("link=Address"); Assert.IsTrue(selenium.IsElementPresent("//div[@id='tabs-3']/p/strong")); selenium.Click("link=Telephone"); Assert.IsTrue(selenium.IsElementPresent("//div[@id='tabs-1']/ul/li/strong")); } catch (AssertionException e) { verificationErrors.AppendLine(browserList[i] + " :: " + e.Message); } finally { selenium.Stop(); } } Assert.AreEqual("", verificationErrors.ToString(), verificationErrors.ToString()); } My problem is i would like to make it so that i can use the code surrounding the 'try' many many times in the rest of the code. I think it has something to do with wrappers, but i can't get a simple answer for this from the web. So in simple terms the only piece of this code which changes is the bit between the try {} the rest is standard code that i have currently used over 100 times and is turning out to be a pain to maintain. Hope this is clear, many thanks.

  • Which is the best and appropriate way to write the code in Winforms ?

    - by Harikrishna
    What is the best way to write the code ? (1) Like directly writing the code in the button_click() event. or (2) Make the function of that code which I write in button_click() event and write this function in one class and then that function I should call in the button_Click() event.Like is it called three-tired approach to write the code ? Like in button_Click() event I write the code to save the records in csv file from datatable.So I should write that code in button_Click() event or I should make one new function and one new class and write that code in that function which is the new class and calling that function in button_Click() event. This is only one example but I am talking about all the code written in my application that which is the appropriate and best way to write the code and what are the benefits ? Note that I write the code in Winforms with c#.

  • Prevent event from parent element to child element in jquery

    - by sonam
    I have binded event as below: $(document).delegate('.budget', 'click', function(e){ if ($(this).hasClass('collapsed')) { $(this).removeClass('collapsed'); $(this).addClass('expanded'); } else if ($(this).hasClass('expanded')) { $(this).removeClass('expanded'); $(this).addClass('collapsed'); } }); Basically this toggles between expand and collapse. I have another event binded as below: $('[id^="tree"]').delegate('.collapsed', 'click', function(e){ var elementId = $(this).attr('id'); hideChildElement(elementId); }); The elements binded by the second event binding are parents of elements binded by first event binding. What happens is that on clicking on the element from the first binding event method also triggers the event binded by second event binding. I want to prevent any events from binding from second event binding to 1st event binding method. If element A is binded to click event from first event binding and B is binded to second event binding (A is inside B or A is child of B), I dont want any event of B to propagate to A. Note I tried e.stopImmediatePropagation(); but did not worked

  • Is it a problem if i query again and again to SQL Server 2005 and 2000?

    - by learner
    Window app i am constructing is for very low end machines (Celeron with max 128 RAM). From the following two approaches which one is the best (I don't want that application becomes memory hog for low end machines):- Approach One:- Query the database Select GUID from Table1 where DateTime <= @givendate which is returning me more than 300 thousands records (but only one field i.e. GUID - 300 thousands GUIDs). Now running a loop to achieve next process of this software based on GUID. Second Approach:- Query the database Select Top 1 GUID from Table1 where DateTime <= @givendate with top 1 again and again until all 300 thousands records done. It will return me only one GUID at a time, and I can do my next step of operation. What do you suggest which approach will use the less Memory Resources?? (Speed / performance is not the issue here).

  • Catch/Intercept all mouse clicks

    - by Hallik
    I have this simple script that catches all mouse clicks, unless you click on something that actually works. Links, flash videos, etc. How can I adjust this so no matter what a user clicks on, before the video loads, new page loads, etc. It sends the simple GET request I built? (function($) { $.fn.saveClicks = function() { $(this).bind('mousedown.clickmap', function(evt) { var clickDocument = (document.documentElement != undefined && document.documentElement.clientHeight != 0) ? document.documentElement : document.body; var width = clickHeatDocument.clientWidth != undefined ? clickDocument.clientWidth : window.innerWidth; var height = clickHeatDocument.clientHeight != undefined ? clickDocument.clientHeight : window.innerHeight; var scrollx = window.pageXOffset == undefined ? clickDocument.scrollLeft : window.pageXOffset; var scrolly = window.pageYOffset == undefined ? clickDocument.scrollTop : window.pageYOffset; var x = evt.clientX + scrollx; var y = evt.clientY + scrolly; $.get('/click-save.php', { "x":evt.pageX, "y":evt.pageY, "click":"true", "w":width, "h":height, "l":escape(document.location.pathname), "d":escape(document.domain) }); }); }; })(jQuery); $(function() { $(document).saveClicks(); });

  • Is there a way to make sure classes implementing an Interface implement static methods?

    - by Tobias Kienzler
    Frist of all, I read erickson's usefull reply to "Why can’t I define a static method in a Java interface?". This question is not about the "why" but about the "how then?". So basically I want one Interface to provide both usual methods and e.g. a getSimilarObject method. For (a made up) example public interface ParametricFunction { /** @return f(x) using the parameters */ static abstract public double getValue(double x, double[] parameters); /** @return The function's name */ static abstract public String getName(); } and then public class Parabola implements ParametricFunction { /** @return f(x) = parameters[0] * x² + parameters[1] * x + parameters[2] */ static public double getValue(double x, double[] parameters) { return ( parameters[2] + x*(parameters[1] + x*parameters[0])); } static public String getName() { return "Parabola"; } } Since this is not allowed in the current Java standard, what is the closest thing to this? The idea behind this is putting several ParametricFunction's in a package and use Reflection to list them all, allowing the user to pick e.g. which one to plot. Obviously one could provide a loader class containing an array of the available ParametricFunction's, but every time a new one is implemented one has to remember adding it there, too.
