  • Manipulating original elements with qTip

    - by pjotr
    I have a bunch of divs on my page and each of them has only the class attribute. In the divs there are some spans, which are set up to display a tooltip with the help of qTip. The tooltip should contain three items: Up: anchor, which should move the OuterDiv up (probably something like this: move up/down in jquery) Down: anchor, which should move the OuterDiv down Delete: anchor, which should remove the calling OuterDiv My code so far: <body> <div class="OuterDiv"> <div class="InnerDiv"> <span class="Position">Position 1</span> </div> </div> <div class="OuterDiv"> <div class="InnerDiv"> <span class="Position">Position 2</span> </div> </div> </body> And scripts: $(document).ready(function () { var qTipContent = '<a href="javascript:void(0)" onclick="">&uarr;</a>&nbsp;&nbsp;&nbsp;'; qTipContent = qTipContent + '<a href="javascript:void(0)" onclick="">&darr;</a>&nbsp;&nbsp;&nbsp;'; qTipContent = qTipContent + '<a href="javascript:void(0)" onclick="">X</a>'; $('.Position').each(function () { $(this).qtip({ content: qTipContent, hide: { fixed: true } }) }); }); How should the onclick function in the qTip content look like?

  • problem linking vba modules in MS Access 2007

    - by Ted
    I am upgrading a database system from Access 2000 db to Access 2007, which communicates with several chemistry measuring devices(pH meter, scale, etc) via an RS 232 serial port. The first db consists of several modules containing vba code that enables the communications with the ports, as well as supports the code behind the forms in the second db. The user, or lab tech, navigates through the forms in the second db to interact with the lab devices, and also to generate the reports which display the info. from the devices. The reports are also part of the second db. The code works in Access 2000, but once I convert it to 2007, the code in the second db cannot find the function calls in the first db that dictate the progression from screen to screen. I have tried importing the modules into the second db, and I have tried linking them, but it still doesn't work. The error message is #438: "Object doesn't support this property or method." Any suggestions would be greatly appreciated. Here is the code for the first function that is not being called correctly: Description: ' This routine is used to return to the calling form and close the active form. ' ' Input: ' strFormCalled --- the active form ' strCallingForm --- the form that called the active form ' blnUnhideOrOpen --- whether to open or just unhide form Public Sub basReturnToCallingForm(ByVal strFormCalled As String, ByVal _ strCallingForm As Variant, Optional blnUnhideOrOpen As Boolean = True) On Error GoTo err_basReturnToCaliingForm If Not basIsBlankString(strCallingForm) And blnUnhideOrOpen Then DoCmd.OpenForm strCallingForm, acNormal Else Call basUnHideForm(strCallingForm) End If Call basCloseForm(strFormCalled) exit_basReturnToCaliingForm: Exit Sub err_basReturnToCaliingForm: Err.Raise Err.Number, "basReturnToCaliingForm", Err.Description End Sub I will post the second function shortly, but I have to go to a meeting... The second funtion that isn't 'working' is a cmdStartClick that is supposed to be called when a user initializes a pump. However, within that function, it's also sticking on a line that is supposed to progress to the next form in the db. The other thing is that the code works in Access 2002, but not in Access 2007...

  • Does the managed main UI thread stay on the same (unmanaged) Operation System thread?

    - by Daniel Rose
    I am creating a managed WPF UI front-end to a legacy Win32-application. The WPF front-end is the executable; as part of its startup routines I start the legacy app as a DLL in a second thread. Any UI-operation (including CreateWindowsEx, etc.) by the legacy app is invoked back on the main UI-thread. As part of the shutdown process of the app I want to clean up properly. Among other things, I want to call DestroyWindow on all unmanaged windows, so they can properly clean themselves up. Thus, during shutdown I use EnumWindows to try to find all my unmanaged windows. Then I call DestroyWindow one the list I generate. These run on the main UI-thread. After this background knowledge, on to my actual question: In the enumeration procedure of EnumWindows, I have to check if one of the returned top-level windows is one of my unmanaged windows. I do this by calling GetWindowThreadProcessId to get the process id and thread id of the window's creator. I can compare the process id with Process.GetCurrentProcess().Id to check if my app created it. For additional security, I also want to see if my main UI-thread created the window. However, the returned thread id is the OS's ThreadId (which is different than the managed thread id). As explained in this question, the CLR reserves the right to re-schedule the managed thread to different OS threads. Can I rely on the CLR to be "smart enough" to never do this for the main UI thread (due to thread-affinity of the UI)? Then I could call GetCurrentThreadId to get the main UI-thread's unmanaged thread id for comparison.

  • How do I make a function in SQL Server that accepts a column of data?

    - by brandon k
    I made the following function in SQL Server 2008 earlier this week that takes two parameters and uses them to select a column of "detail" records and returns them as a single varchar list of comma separated values. Now that I get to thinking about it, I would like to take this table and application-specific function and make it more generic. I am not well-versed in defining SQL functions, as this is my first. How can I change this function to accept a single "column" worth of data, so that I can use it in a more generic way? Instead of calling: SELECT ejc_concatFormDetails(formuid, categoryName) I would like to make it work like: SELECT concatColumnValues(SELECT someColumn FROM SomeTable) Here is my function definition: FUNCTION [DNet].[ejc_concatFormDetails](@formuid AS int, @category as VARCHAR(75)) RETURNS VARCHAR(1000) AS BEGIN DECLARE @returnData VARCHAR(1000) DECLARE @currentData VARCHAR(75) DECLARE dataCursor CURSOR FAST_FORWARD FOR SELECT data FROM DNet.ejc_FormDetails WHERE formuid = @formuid AND category = @category SET @returnData = '' OPEN dataCursor FETCH NEXT FROM dataCursor INTO @currentData WHILE (@@FETCH_STATUS = 0) BEGIN SET @returnData = @returnData + ', ' + @currentData FETCH NEXT FROM dataCursor INTO @currentData END CLOSE dataCursor DEALLOCATE dataCursor RETURN SUBSTRING(@returnData,3,1000) END As you can see, I am selecting the column data within my function and then looping over the results with a cursor to build my comma separated varchar. How can I alter this to accept a single parameter that is a result set and then access that result set with a cursor?

  • FLEX, how to specify parent html item, when I call external functions ?

    - by Patrick
    hi, I'm calling a javascript function from my flex application to set width and height of my html wrapper according to application size. However, I've many flex applications on my page and the wrappers have not id attribute. I'm using a unique javascript function and passing it the parameters. How could I specify the "parent" html element in these parameters ? Following is the code: Actionscript: if (ExternalInterface.available) ExternalInterface.call("changeSize",id, width, height); Javascript: <script type="text/JavaScript"> function changeSize(id, width, height) { console.log(id); console.log(width); console.log(height); } Wrapper: <div class="filefield-file clear-block"> <div class="filefield-icon field-icon-video-x-flv"> <img class="field-icon-video-x-flv" alt="video/x-flv icon" src="http://localhost/drupal/sites/all/modules/filefield/icons/protocons/16x16/mimetypes/video-x-generic.png"></div> <div style="background-color: rgb(255, 255, 255); width: 400px;"> <embed style="display: block;" src="/drupal/videoPlayer.swf?file=http://localhost/drupal/sites/default/files/files/projects/Project3/videos/9565274.flv" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer" bgcolor="#ffffff" allowfullscreen="true" autoplay="true" flashvars="file=http://localhost/drupal/sites/default/files/files/projects/Project3/videos/9565274.flv" height="400" width="400"> <div>Scheduling Video</div> </div> </div>

  • Keyboard not dismissed

    - by sgosha
    I am developing a messaging application that have SMS.app-like UI. Conversation screen has text input field at the bottom which is moved up with keyboard. Tapping on conversation area dismisses keyboard by calling resignFirstResponder method on UITextView that we use. This usually works fine, but users report a weird bug which I can't reproduce and fix. People say that sometimes onscreen keyboard doesn't go away when they tap on conversation area, though text input field loses input focus. Once the view enters that abnormal state users are able to type with keyboard, but text that is being entered is not visible anywhere. This bug happens in one of conversation views and since then no one text input field in other views doesn't work as expected. The only way to stop this weird behavior is killing application from multitasking bar. Even more weird thing is that keyboard stays visible while navigating between view controllers in UINavigationController. I noticed two things: - if tap on ' Anyone else experiencing same problems. Any ideas on what may cause this bug?

  • Noise with multi-threaded raytracer

    - by herber88
    This is my first multi-threaded implementation, so it's probably a beginners mistake. The threads handle the rendering of every second row of pixels (so all rendering is handled within each thread). The problem persists if the threads render the upper and lower parts of the screen respectively. Both threads read from the same variables, can this cause any problems? From what I've understood only writing can cause concurrency problems... Can calling the same functions cause any concurrency problems? And again, from what I've understood this shouldn't be a problem... The only time both threads write to the same variable is when saving the calculated pixel color. This is stored in an array, but they never write to the same indices in that array. Can this cause a problem? Multi-threaded rendered image (Spam prevention stops me from posting images directly..) Ps. I use the exactly same implementation in both cases, the ONLY difference is a single vs. two threads created for the rendering.

  • naming a function that exhibits "set if not equal" behavior

    - by Chris Sears
    This might be an odd question, but I'm looking for a word to use in a function name. I'm normally good at coming up with succinct, meaningful function names, but this one has me stumped so I thought I'd appeal for help. The function will take some desired state as an argument and compare it to the current state. If no change is needed, the function will exit normally without doing anything. Otherwise, the function will take some action to achieve the desired state. For example, if wanted to make sure the front door was closed, i might say: my_house.<something>_front_door('closed') What word or term should use in place of the something? I'd like it to be short, readable, and minimize the astonishment factor. A couple clarifying points... I would want someone calling the function to intuitively know they didn't need to wrap the function an 'if' that checks the current state. For example, this would be bad: if my_house.front_door_is_open(): my_house.<something>_front_door('closed') Also, they should know that the function won't throw an exception if the desired state matches the current state. So this should never happen: try: my_house.<something>_front_door('closed') except DoorWasAlreadyClosedException: pass Here are some options I've considered: my_house.set_front_door('closed') my_house.setne_front_door('closed') # ne=not equal, from the setne x86 instruction my_house.ensure_front_door('closed') my_house.configure_front_door('closed') my_house.update_front_door('closed') my_house.make_front_door('closed') my_house.remediate_front_door('closed') And I'm open to other forms, but most I've thought of don't improve readability. Such as... my_house.ensure_front_door_is('closed') my_house.conditionally_update_front_door('closed') my_house.change_front_door_if_needed('closed') Thanks for any input!

  • BufferedImage.getGraphics() resulting in memory leak, is there a fix?

    - by user359202
    Hi friends, I'm having problem with some framework API calling BufferedImage.getGraphics() method and thus causing memory leak. What this method does is that it always calls BufferedImage.createGraphics(). On a windows machine, createGraphics() is handled by Win32GraphicsEnvironment which keeps a listeners list inside its field displayChanger. When I call getGraphics on my BufferedImage someChart, someChart's SurfaceManager(which retains a reference to someChart) is added to the listeners map in Win32GraphicsEnvironment, preventing someChart to be garbage collected. Nothing afterwards removes someChart's SurfaceManager from the listeners map. In general, the summarized path stopping a BufferedImage from being garbage collected, once getGraphics is called, is as follows: GC Root - localGraphicsEnvironment(Win32GraphicsEnvironment) - displayChanger(SunDisplayChanger) - listeners(Map) - key(D3DChachingSurfaceManager) - bImg(BufferedImage) I could have changed the framework's code so that after every called to BufferedImage.getGraphics(), I keep a reference to the BufferedImage's SurfaceManager. Then, I get hold of localGraphicsEnvironment, cast it to Win32GraphicsEnvironment, then call removeDisplayChangedListener() using the reference to the BufferedImage's SurfaceManager. But I don't think this is a proper way to solve the problem. Could someone please help me with this issue? Thanks a lot!

  • Scheme Function to reverse elements of list of 2-list

    - by sudhirc
    This is an exercise from EOPL. Procedure (invert lst) takes lst which is a list of 2-lists and returns a list with each 2-list reversed. (define invert (lambda (lst) (cond((null? lst ) '()) ((= 2 (rtn-len (car lst))) ( cons(swap-elem (car lst)) (invert (cdr lst)))) ("List is not a 2-List")))) ;; Auxiliry Procedure swap-elements of 2 element list (define swap-elem (lambda (lst) (cons (car (cdr lst)) (car lst)))) ;; returns lengh of the list by calling (define rtn-len (lambda (lst) (calc-len lst 0))) ;; calculate length of the list (define calc-len (lambda (lst n) (if (null? lst) n (calc-len (cdr lst) (+ n 1))))) This seems to work however looks very verbose. Can this be shortened or written in more elegant way ? How I can halt the processing in any of the individual element is not a 2-list? At the moment execution proceed to next member and replacing current member with "List is not a 2-List" if current member is not a 2-list.

  • Passing System classes as constructor parameters

    - by mcl
    This is probably crazy. I want to take the idea of Dependency Injection to extremes. I have isolated all System.IO-related behavior into a single class so that I can mock that class in my other classes and thereby relieve my larger suite of unit tests of the burden of worrying about the actual file system. But the File IO class I end up with can only be tested with integration tests, which-- of course-- introduces complexity I don't really want to deal with when all I really want to do is make sure my FileIO class calls the correct System.IO stuff. I don't need to integration test System.IO. My FileIO class is doing more than simply wrapping System.IO functions, every now and then it does contain some logic (maybe this is the problem?). So what I'd like is to be able to test my File IO class to ensure that it makes the correct system calls by mocking the System.IO classes themselves. Ideally this would be as easy as having a constructor like so: public FileIO( System.IO.Directory directory, System.IO.File file, System.IO.FileStream fileStream ) { this.Directory = directory; this.File = file; this.FileStream = fileStream; } And then calling in methods like: public GetFilesInFolder(string folderPath) { return this.Directory.GetFiles(folderPath) } But this doesn't fly since the System.IO classes in question are static classes. As far as I can tell they can neither be instantiated in this way or subclassed for the purposes of mocking.

  • OO Design: use Properties or Overloaded methods?

    - by Robert Frank
    Question about OO design. Suppose I have a base object vehicle. And two descendants: truck and automobile. Further, suppose the base object has a base method: FixFlatTire(); abstract; When the truck and automobile override the base object's, they require different information from the caller. Am I better off overloading FixFlatTire like this in the two descendant objects: Procedure Truck.FixFlatTire( OfficePhoneNumber: String; NumberOfAxles: Integer): Override; Overload; Procedure Automobile.FixFlatTire( WifesPhoneNumber: String; AAAMembershipID: String): Override; Overload; Or introducing new properties in each of the descendants and then setting them before calling FixFlatTire, like this: Truck.OfficePhoneNumber := '555-555-1212'; Truck.NumberOfAxles := 18; Truck.FixFlatTire(); Automobile.WifesPhoneNumber := '555-555-2323'; Automobile.AAAMembershipID := 'ABC'; Automobile.FixFlatTire();

  • Unit testing a method with many possible outcomes

    - by Cthulhu
    I've built a simple~ish method that constructs an URL out of approximately 5 parts: base address, port, path, 'action', and a set of parameters. Out of these, only the address part is mandatory, the other parts are all optional. A valid URL has to come out of the method for each permutation of input parameters, such as: address address port address port path address path address action address path action address port action address port path action address action params address path action params address port action params address port path action params andsoforth. The basic approach for this is to write one unit test for each of these possible outcomes, each unit test passing the address and any of the optional parameters to the method, and testing the outcome against the expected output. However, I wonder, is there a Better (tm) way to handle a case like this? Are there any (good) unit test patterns for this? (rant) I only now realize that I've learned to write unit tests a few years ago, but never really (feel like) I've advanced in the area, and that every unit test is a repeat of building parameters, expected outcome, filling mock objects, calling a method and testing the outcome against the expected outcome. I'm pretty sure this is the way to go in unit testing, but it gets kinda tedious, yanno. Advice on that matter is always welcome. (/rant) (note) christmas weekend approaching, probably won't reply to suggestions until next week. (/note)

  • Cannot redeclare class on a copy of a site

    - by Polity
    I've developed a small SMS utility for a customer in PHP. The details are of non-importance. This project is hosted in: http://project.example.com/customer1 Now a second customer requests almost the same functionality, one cheap way of providing this is to copy the project from the first customer and modify it slightly. So i made a direct copy of the project for customer1 to another folder for customer 2. This project is hosted in: http://project.example.com/customer2 Now when i try and run the project for customer2 (calling a single page), i get the error message: Fatal error: Cannot redeclare class SmsService in /var/www/html/project/customer1/application/service.class.php on line 3 Here, service.class.php is a simple interface with 3 methods: interface SmsService { public function SendSms($mobile, $customerId, $customerName, $message); public function QueryIncomingResponse(); public function CleanExpiredConfirmations($maxConfirmationDays); } printing the backtrace in service.class.php reveals something interresting: #0 require_once() called at [/var/www/html/project/customer2/endpoint/queryIncomingResponse.php:2] Fatal error: Cannot redeclare class SmsService in /var/www/html/project/customer1/application/service.class.php on line 3 Line 2 in queryIncomingResponses is the very first require line there is. Line 3 in service.class.php is the first statement there is in the file (Line 2 is an empty line and line 1 is the php file opening tag). Naturally, I only work with relative requires (double checked this) so there is no way one include/require from customer2 actually refers to a file for customer1. It seems to me that in some way SmsService and other classes gets cached by PHP. (I have little control over the server environment). One solution to this would be namespaces. Unfortunatly, we work with PHP 5.1.7 where namespaces are not a part of the language feature just yet. Another way would be to mimic namespaces by prefixing all classes but this approach just feels dirty. Does anyone have more information on this problem and possibly solutions? Many thanks in advance!

  • check array against each other, to determine response

    - by Johnny
    So, I have an array that has 6 variables in it that I need to check against each other.. to determine what to return to the script calling the function.. All fields are of the datetime type from the database they are derived from. the fields: in1 out1 in2 out2 in3 out3 Array: Array( 'in1' => '2012-04-02 10:00:00), `out1` => '2012-04-02 14:00:00`, `in2` => '2012-04-02 14:30:00`, `out2` => '2012-04-02 18:00:00`, `in3` => NULL, `out3` => NULL ) the response: clocked_in or clocked_out What I need to figure out is, the best way to determine if the user is clocked in or clocked out by checking against this array.. so, if in1, out1 and in2 are not NULL then the user would be clocked in.. if in1 is not NULL but out1 is NULL then the user would be clocked out, etc.. Anyone have any ideas on the easiest way to achieve this without too many if statements?

  • Programmatically Update UITableView in Response to Button Press

    - by Kyle Begeman
    I have a completely custom view that holds a UITableView and a Custom Tab Bar (basically a UIView that contains 6 UIButtons). I am loading data from a plist file, and then I am sorting the data into multiple arrays based on categories (an array for misc items, and array for mail items, etc.) Each button in the tab bar represents a category, and when I press the button I call the custom function "miscSelected" and so on. How can I have the table view completely reload and then display the tableview based on the array selected (select the misc category and the tableview clears itself and loads the misc array data, same for any other category)? The method I have experimented with is created and NSString named "selection" and then in each button function I set selected to equal whatever section I am selecting. In my cellForRoxAtIndexPath method I have this: if ([self.selection isEqualToString:@"All Items"]) { NSArray *mainDataArray = [NSArray arrayWithContentsOfFile:self.plistFile]; NSSortDescriptor *brandDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [NSArray arrayWithObject:brandDescriptor]; self.sortedData = [mainDataArray sortedArrayUsingDescriptors:sortDescriptors]; } else if ([self.selection isEqualToString:@"Misc Items"]){ self.sortedData = [NSArray arrayWithContentsOfFile:self.plistFile]; } cell.itemTitle.text = [[self.sortedData objectAtIndex:indexPath.row] objectForKey:@"name"]; For the sake of example and testing I am simply displaying the same data, just one button displays it in alphabetical order and the other does not. This code works only when I start to scroll down and back up, but it does not actually update on button press. Calling myTable reloadData does not do anything either. Any help would be great, thanks!

  • What is the most efficient way of associating information with a Type in .Net?

    - by Miguel Angelo
    I want to associate custom data to a Type, and retrieve that data in run-time, blasingly fast. This is just my imagination, of my perfect world: var myInfo = typeof(MyClass).GetMyInformation(); this would be very fast... of course this does not exist! If it did I would not be asking. hehe ;) This is the way using custom attributes: var myInfo = typeof(MyClass).GetCustomAttribute("MyInformation"); this is slow because it requires a lookup of the string "MyInformation" This is a way using a Dictionary<Type, MyInformation: var myInfo = myInformationDictionary[typeof(MyClass)]; This is also slow because it is still a lookup of 'typeof(MyClass)'. I know that dictionary is very fast, but this is not enough... it is not as fast as calling a method. It is not even the same order of speed. I am not saying I want it to be as fast as a method call. I want to associate information with a type and access it as fast as possible. I am asking whether there is a better way, or event a best way of doing it. Any ideas?? Thanks!

  • How does Access 2007's moveNext/moveFirst/, etc., feature work?

    - by Chris M
    I'm not an Access expert, but am an SQL expert. I inherited an Access front-end referencing a SQL 2005 database that worked OK for about 5000 records, but is failing miserably for 800k records... Behind the scenes in the SQL profiler & activity manager I see some kind of Access query like: SELECT "MS1"."id" FROM "dbo"."customer" "MS1" ORDER BY "MS1"."id" The MS prefix doesn't appear in any Access code I can see. I'm suspicious of the built-in Access navigation code: DoCmd.GoToRecord , , acNext The GoToRecord has AcRecord constant, which includes things like acFirst, acLast, acNext, acPrevious and acGoTo. What does it mean in a database context to move to the "next" record? This particular table uses an identity column as the PK, so is it internally grabbing all the IDs and then moving to the one that is the next highest??? If so, how would it work if a table was comprised of three different fields for the PK? Or am I on the wrong track, and something else in Access is calling that statement? Unfortunately I see a ton of prepared statements in the profiler. THanks!

  • How to use clearInterval() and then make changes to the DOM?

    - by George D.
    I have this code and the problem I have is that I want to stop the loop and then replace the text 'Done!' that comes from the sms-loader.php script with the "textnew" string. Problem is that the loop occurs one more time so the text in the div.checkstatus field is again replaced by the calling php script. The strange thing is that I see the log message and again I get a new (and final) request, although the ordering is the opposite (first stop then replace text()) in my script. I need to understand why this is happening. $(document).ready(function() { var interval = ""; $('.checkstatus').each(function(){ var msgid = $(this).data('msg') $this = $(this), hid = $this.data('history'), textnew = '<a href="sms-dstatus.php?id='+msgid+'&sid=' +hid+ '&amp;keepThis=true&amp;TB_iframe=true&amp;height=430&amp;width=770" title="Delivery Status" class="thickbox"><img src="../template/icons/supermini/chart_curve.png" alt="status" width="16" height="16" /></a>'; interval = setInterval(function() { $this.load('../pages/sms-loader.php?id='+msgid); // stop the loop if($this.text()=='Done!'){ // stop it clearInterval(interval); console.log(textnew); this.html(textnew); /// this line is the problem } }, 5000); // 5 secs }); });

  • Pass object or id

    - by Charles
    This is just a question about best practices. Imagine you have a method that takes one parameter. This parameter is the id of an object. Ideally, I would like to be able to pass either the object's id directly, or just the object itself. What is the most elegant way to do this? I came up with the following: def method_name object object_id = object.to_param.to_i ### do whatever needs to be done with that object_id end So, if the parameter already is an id, it just pretty much stays the same; if it's an object, it gets its id. This works, but I feel like this could be better. Also, to_param returns a string, which could in some cases return a "real" string (i.e. "string" instead of "2"), hence returning 0 upon calling to_i on it. This could happen, for example, when using the friendly id gem for classes. Active record offers the same functionality. It doesn't matter if you say: Table.where(user_id: User.first.id) # pass in id or Table.where(user_id: User.first) # pass in object and infer id How do they do it? What is the best approach to achieve this effect?

  • How to best manage multi-frame MovieClips with classes?

    - by Arms
    After switching to AS3, I've been having a hell of a time figuring out the best way to manage MovieClips that have UI elements spread across multiple frames with a single class. An example that I am working on now is a simple email form. I have a MovieClip with two frames: the 1st frame has the form elements (text inputs, submit button) the 2nd frame has a "thank you" message and a button to go back to the first frame (to send another email) In the library I have linked the MovieClip to a custom class (Emailer). My immediate problem is how do I assign a MouseEvent.CLICK event to the button on the 2nd frame? I should note at this point that I am trying to avoid putting code on the timeline (except for stop() calls). This is how I am 'solving' the problem now: Emailer registers an event listener for a frame change ( addEventListener("frame 2", onFrameChange) ) On the 2nd frame of the MovieClip I am calling dispatchEvent(new Event("frame 2")); (I would prefer to not have this code on the frame, but I don't know what else to do) My two complaints with this method are that, first I have calls to addEventListener spread out across different class methods (I would rather have all UI event listeners registered in one method), and second that I have to dispatch those custom "onFrameChange" events. The second complaint grows exponentially for MovieClips that have more than just 2 frames. My so called solution feels makes me feel dirty and makes my brain hurt. I am looking for any advice on what to do differently. Perhaps there's a design pattern I should be looking at? Should I swallow my pride and write timeline code even though the rest of my application is written in class files (and I abhor the Flash IDE code editor)? I absolutely LOVE the event system, and have no problem coding applications with it, but I feel like I'm stuck thinking in terms of AS2 when working with mutl-frame movieclips and code. Any and all help would be greatly appreciated.

  • Building simple jQuery plugin, need assistance

    - by kirisu_kun
    Hi there, I'm building my first ever jQuery plugin (it's just a simple experiment). Here's what I have so far: (function($){ $.fn.extend({ auchieFader: function(options) { var defaults = { mask: '', topImg : '', } var options = $.extend(defaults, options); return this.each(function() { var o = options; var obj = $(this); var masker = $(o.mask, obj); masker.hover(function () { $(o.topImg).stop().animate({ "opacity": "0" }, "slow"); }, function () { $(o.topImg).stop().animate({ "opacity": "1" }, "slow"); }); }); } }); })(jQuery); I'm then calling the plugin using: $('.fader').auchieFader({mask: ".mask", topImg: ".top"}); If I then add another request say: $('.fader2').auchieFader({mask: ".mask", topImg: ".top"}); Then no matter what instance of my 2 faders I hover both of them will trigger. I know this is because my mask mask and topImg options have the same class - but how can I modify the plugin to allow for these items to have the same class? I know it's probably something really simple, but I'm still finding my way with jQuery and Javascript in general. Any other tips on improving my code would also be greatly appreciated! Cheers, Chris

  • Filtering Questions (posts) by tag_name in TagController#index passing /tags?tag_name=something

    - by bgadoci
    I am trying to get my TagsController#index action to display only the Questions that contain certain tags when passing the search parameter tag_name. I am not getting an error just can't get the filter to work correctly such that upon receiving the /tags?tag_name=something url, only those questions are displayed . Here is the setup: class Tag < ActiveRecord::Base belongs_to :question def self.search(str) return [] if str.blank? cond_text = str.split.map{|w| "tag_name LIKE ? "}.join(" OR ") cond_values = str.split.map{|w| "%#{w}%"} all(:order => "created_at DESC", :conditions => (str ? [cond_text, *cond_values] : [])) end end and class Question < ActiveRecord::Base has_many :tags, :dependent => :destroy end tag link that would send the URL to the TagsController looks like this: <%= link_to(tag_name, tags_path(:tag_name => tag_name)) %> and outputs: /tags?tag_name=something In my /views/tags/index.html.erb view I am calling the questions by rendering a partial /views/questions/_question.html.erb. <%= render :partial => @questions %> When I send the URL with the search parameter nothing happens. Here is my TagsController#index action: def index @tags = Tag.search(params[:search]).paginate :page => params[:page], :per_page => 5 @tagsearch = Tag.search(params[:search]) @tag_counts = Tag.count(:group => :tag_name, :order => 'count_all DESC', :limit => 100) @questions = Question.all( :order => 'created_at DESC', :limit => 50) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @tags } end end How can I properly filter questions displayed in the /views/tags/index.html.erb file for the parameter tag.tag_name?
