  • Adding a Click event to a submit button and then submitting the form

    - by Abs
    Hello all, I have a form with a submit button. I have attached a click event to that submit button using JQuery. Once I did this my form wasn't submitting, I thought this was because of the event I added- if I remove that click event it submits the form successfully. I have tried giving my form an id and calling the submit function but this was not successful either. What can I do? $('#submit_gen').click(function() { $('#genbtn').html('<img src="images/ajax-loader.gif" alt="loading" />'); $('#action_form').submit(); }); The HTML: <form id="action_form" action="generate.php" method="post" enctype="multipart/form-data"> <input id="file_upload" type="file" name="upload" onchange="file_select();"/> <input type="text" id="overlay_input"> <div id="genbtn" class="genbtn"> <input id="submit_gen" type="submit" value="Upload"> </div> </form> Thanks all

  • Parallelizing for loop

    - by vman049
    I have MATLAB code which I'm trying to parallelize with a simple change from "for" to "parfor." I'm unable to do so because of an error I'm receiving on the variable "votes" which states: Valid indices for 'votes' are restricted in PARFOR loops. Explanation: For MATLAB to execute parfor loops efficiently, the amount of data sent to the MATLAB workers must be minimal. One of the ways MATLAB achieves this is by restricting the way variables can be indexed in parfor iterations. The indicated variable is indexed in a way that is incompatible with parfor. Suggested Action: Fix the indexing. For a description of the indexing restrictions, see “Sliced Variables” in the Parallel Computing Toolbox documentation. Below is my code: votes = zeros(num_layers, size(spikes, 1), size(SVMs_layer1, 1)); predDir = zeros(size(spikes, 1), 1); chronProb = zeros([num_layers, size(chronDists)]); for i = 1:num_layers switch i case 1 B = B1; k_elem_temp = k_elem1; rest_elem_temp = rest_elem1; case 2 B = B2; k_elem_temp = k_elem2; rest_elem_temp = rest_elem2; case 3 B = B3; k_elem_temp = k_elem3; rest_elem_temp = rest_elem3; end for j = 1:length(chronPred) if chronDists(i, j, :) ~= 0 parfor k = 1:8 chronProb(i, j, k) = logistic(B{k}(1) + chronDists(i, j, k).*(B{k}(2))); votes(i, j, k_elem_temp(k, :)) = votes(i, j, k_elem_temp(k, :)) + chronProb(i, j, k)/num_k(i)/num_layers; votes(i, j, rest_elem_temp(k, :)) = votes(i, j, rest_elem_temp(k, :)) + (1 - chronProb(i, j, k))/num_rest(i)/num_layers; end end end end Do you have any suggestions as to how I could adjust my code so that it runs in parallel? Thank you!

  • Should I re-use UI elements across view controllers?

    - by Endemic
    In the iPhone app I'm currently working on, I'd like two navigation controllers (I'll call them A and B) to have toolbars that are identical in appearance and function. The toolbar in question will look like this: [(button) (flexible-space) (label)] For posterity's sake, the label is actually a UIBarButtonItem with a custom view. My design requires that A always appear directly before B on the navigation stack, so B will never be loaded without A having been loaded. Given this layout, I started wondering, "Is it worth it to re-use A's toolbar items in B's toolbar?" As I see it, my options are: 1. Don't worry about re-use, create the toolbar items twice 2. Create the toolbar items in A and pass them to B in a custom initializer 3. Use some more obscure method that I haven't thought of to hold the toolbar constant when pushing a view controller As far as I can see, option 1 may violate DRY, but guarantees that there won't be any confusion on the off chance that (for example) the button may be required to perform two different (no matter how similar) functions for either view controller in future versions of the app. Were that to happen, options 2 or 3 would require the target-action of the button to change when B is loaded and unloaded. Even if the button were never required to perform different functions, I'm not sure what its proper target would be under option 2. All in all, it's not a huge problem, even if I have to go with option 1. I'm probably overthinking this anyway, trying to apply the dependency injection pattern where it's not appropriate. I just want to know the best practice should this situation arise in a more extreme form, like if a long chain of view controllers need to use identical (in appearance and function) UI elements.

  • Built in background-scheduling system in .NET?

    - by Lasse V. Karlsen
    I ask though I doubt there is any such system. Basically I need to schedule tasks to execute at some point in the future (usually no more than a few seconds or possibly minutes from now), and have some way of cancelling that request unless too late. Ie. code that would look like this: var x = Scheduler.Schedule(() => SomethingSomething(), TimeSpan.FromSeconds(5)); ... x.Dispose(); // cancels the request Is there any such system in .NET? Is there anything in TPL that can help me? I need to run such future-actions from various instances in a system here, and would rather avoid each such class instance to have its own thread and deal with this. Also note that I don't want this (or similar, for instance through Tasks): new Thread(new ThreadStart(() => { Thread.Sleep(5000); SomethingSomething(); })).Start(); There will potentially be a few such tasks to execute, they don't need to be executed in any particular order, except for close to their deadline, and it isn't vital that they have anything like a realtime performance concept. I just want to avoid spinning up a separate thread for each such action.

  • Why won't my UITableViewCell deselect and update its text?

    - by Josh
    I have a UITableView with a list of stories and a cell at the bottom that loads more stories. I am trying to make the "More Stories..." cell deselect and change its text to "Loading..." when clicked. I have searched all over the internet and all over stackoverflow and I cant figure out why my code isnt working right. Right now, when the "More Stories..." cell is clicked, it stays selected and doesnt ever change its text. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; if (storyIndex == [stories count]) { UITableViewCell *moreCell = [tableView dequeueReusableCellWithIdentifier:@"more"]; if (moreCell == nil) { moreCell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"more"] autorelease]; } // Set up the cell moreCell.textLabel.text = @"Loading..."; [tableView deselectRowAtIndexPath:indexPath animated:YES]; [self moreStories]; } else { NSLog(@"%@",[[stories objectAtIndex: storyIndex] objectForKey: @"link"]); webViewController *webController; webController = [[webViewController alloc] initWithURLPassed:[[stories objectAtIndex: storyIndex] objectForKey: @"link"]]; [self.navigationController pushViewController:webController animated:YES]; [webController release]; webController =nil; self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:nil action:nil]; } }

  • Modifying Django's pre_save/post_save Data

    - by Rodrogo
    Hi, I'm having a hard time to grasp this post_save/pre_save signals from django. What happens is that my model has a field called status and when a entry to this model is added/saved, it's status must be changed accordingly with some condition. My model looks like this: class Ticket(models.Model): (...) status = models.CharField(max_length=1,choices=OFFERT_STATUS, default='O') And my signal handler, configured for pre_save: def ticket_handler(sender, **kwargs): ticket = kwargs['instance'] (...) if someOtherCondition: ticket.status = 'C' Now, what happens if I put aticket.save() just bellow this last line if statement is a huge iteration black hole, since this action calls the signal itself. And this problem happens in both pre_save and post_save. Well... I guess that the capability of altering a entry before (or even after) saving it is pretty common in django's universe. So, what I'm doing wrong here? Is the Signals the wrong approach or I'm missing something else here? Also, would it be possible to, once this pre_save/post_save function is triggered, to access another model's instance and change a specific row entry on that? Thanks

  • My UITextView delegate method doesn't respond

    - by user611967
    Hi guys. I would like to start we that i'm not a very good english speaker, so excuse me if something is wrong. So I have this code header file : import @interface macViewController : UIViewController { UINavigationItem *navItem; UITextView *iTextView; } @property (nonatomic, retain) IBOutlet UINavigationItem *navItem; @property (nonatomic, retain) IBOutlet UITextView *iTextView; (IBAction) btnClicked; @end implementation file : import "macViewController.h" @implementation macViewController @synthesize navItem, iTextView; (IBAction) btnClicked { if (self.editing == YES) { self.editing = NO; [iTextView resignFirstResponder]; UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Data Saved" message:@"Your data was saved" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; } else { self.editing = YES; [iTextView becomeFirstResponder]; } NSLog(@"works"); self.navItem.rightBarButtonItem = self.editButtonItem; self.navItem.rightBarButtonItem.action = @selector(btnClicked); } (void) textViewDidChangeUITextView *)textView { NSLog(@"works"); } So like you guess it's a view based app wich when i tap Edit button the keyboard pops-up then i press Done button and keyboard disappear and appear a alert view. SO I WANTED TO MAKE THEN I TOUCH THE TEXTVIEW, EDIT BUTTON TO BECOME DONE BUTTON ... THE PROBLEM IS THAT THE METHOD I DELEGATE TO IT DOESN'T RESPOND ... (USING CONSOLE I SAW THAT NOTHING HAPPENS) ...

  • Make an abstract class or use a processor?

    - by Tim Murphy
    I'm developing a class to compare two directories and run an action when a directory/file in the source directory does not exist in destination directory. Here is a prototype of the class: public abstract class IdenticalDirectories { private DirectoryInfo _sourceDirectory; private DirectoryInfo _destinationDirectory; protected abstract void DirectoryExists(DirectoryInfo sourceDirectory, DirectoryInfo destinationDirectory); protected abstract void DirectoryDoesNotExist(DirectoryInfo sourceDirectory, DirectoryInfo destinationDirectory); protected abstract void FileExists(DirectoryInfo sourceDirectory, DirectoryInfo destinationDirectory); protected abstract void FileDoesNotExist(DirectoryInfo sourceDirectory, DirectoryInfo destinationDirectory); public IdenticalDirectories(DirectoryInfo sourceDirectory, DirectoryInfo destinationDirectory) { ... } public void Run() { foreach (DirectoryInfo sourceSubDirectory in _sourceDirectory.GetDirectories()) { DirectoryInfo destinationSubDirectory = this.GetDestinationDirectoryInfo(subDirectory); if (destinationSubDirectory.Exists()) { this.DirectoryExists(sourceSubDirectory, destinationSubDirectory); } else { this.DirectoryDoesNotExist(sourceSubDirectory, destinationSubDirectory); } foreach (FileInfo sourceFile in sourceSubDirectory.GetFiles()) { FileInfo destinationFile = this.GetDestinationFileInfo(sourceFile); if (destinationFile.Exists()) { this.FileExists(sourceFile, destinationFile); } else { this.FileDoesNotExist(sourceFile, destinationFile); } } } } } The above prototype is an abstract class. I'm wondering if it would be better to make the class non-abstract and have the Run method receiver a processor? eg. public void Run(IIdenticalDirectoriesProcessor processor) { foreach (DirectoryInfo sourceSubDirectory in _sourceDirectory.GetDirectories()) { DirectoryInfo destinationSubDirectory = this.GetDestinationDirectoryInfo(subDirectory); if (destinationSubDirectory.Exists()) { processor.DirectoryExists(sourceSubDirectory, destinationSubDirectory); } else { processor.DirectoryDoesNotExist(sourceSubDirectory, destinationSubDirectory); } foreach (FileInfo sourceFile in sourceSubDirectory.GetFiles()) { FileInfo destinationFile = this.GetDestinationFileInfo(sourceFile); if (destinationFile.Exists()) { processor.FileExists(sourceFile, destinationFile); } else { processor.FileDoesNotExist(sourceFile, destinationFile); } } } } What do you see as the pros and cons of each implementation?

  • why would i get a different views when called from different controller actions in asp.net-mvc

    - by ooo
    I have 2 different controller actions. As seen below, one calls the same view as the other one. The fitness version has a bunch of jquery ui tabs. public ActionResult FitnessByTab(string tab, DateTime entryDate) { return View("Fitness", GetFitnessVM(DateTime.Today.Date)); } public ActionResult Fitness() { return View(GetFitnessVM(DateTime.Today.Date)); } private FitnessVM GetFitnessVM(DateTime dt) { FitnessVM vm = new FitnessVM(); vm.Date = dt; // a bunch of other date that comes from a database return vm; } the issue is that on the action FitnessByTab() the tabs dont load correctly but on the Fitness() it loads fine. How could this be as my understanding is that they would be going through the same code path at that point. As you can see i am hard coded both to the same date to make sure its not a different date causing the issue. EDIT Issues has been solved. It was the relative referencing of all my links. I didn't get any issues until i used firebug that highlighted some missing references due to "../../" instead of Url.Content("

  • Manipulating data in sql / asp.net / c# - how?

    - by SLC
    Not sure how to word the question... Basically, so far all my SQL stuff has been stored procedures and dumped into a gridview. The odd case where I had to perform an action based on a value (such as highlighting a row green if a certain value was true) were done as the gridview was rendering in one of the overrides. Now however I have to do something far more complicated - pull three sets of data down, run a series of checks on all three and some date related checks and stuff, then populate a gridview with some of the items. In logic terms, I want to run three queries, and store the lists of results (presumably in Lists?) then run some logic, then populate the gridview. Specifically what I don't know how to do is: Best way of pulling the data, and putting it into a List or other datastructure that lets me easily run through it, and retrieve data based on column (myList.age, or more likely, myList["Age"]). One I have compared the data, I assume I create a new list that will be put into the gridview... how do I put the contents of a list INTO a gridview? How would I add other stuff such as buttons or checkboxes at the same time? Any nudge in the right direction would be appreciated! Particularly doing cool stuff with lists and sql (if there is anything cool you can do with them)

  • Page does update with details from the database after i hit a button

    - by swathi
    I have a code and the way it should work is,when they click on NEW CUSTOMER,it takes them to test1.php where in they enter the details and they hit submit.it saves all the details in properly in the database and when i go back and hit REFRESH ,it should come up with the customer details which they had entered in previously. But what happens is, when i click on the REFRESH,it refreshes the same old page which is empty.I wanted to find out where am i missing the logic.Thanks in advance. The sample code would be <tr> <td class="tdvisitbig" colspan="5">THIS IS A TEST</td> </tr> <tr> <td class='tdvisitbig' colspan="5"><input type="button" onClick="openVisit('test1.php?id=<?=$key?>&name=<?=$name?>');return false;" value="NEW CUSTOMER" class="submit">&nbsp;<input type="button" value="REFRESH" name="add_xyz" class="submit" onClick="document.add.target='_self';document.add.action='test3.php?redirect=visit&section=test page';document.add.submit();"></td> </tr> <? $q = "SELECT address,customernum,status FROM customer WHERE name='$name' ORDER BY customernum"; $r = mysql_query( $q , $Link ); while( $rw = mysql_fetch_assoc( $r ) ) { extract( $rw ); ?> <tr> <? } ?>

  • Submitting form with Ajax

    - by Sidetracking
    So I'm completely lost on how to submit a form with Ajax. I'm fairly new to Javascript and hopefully I'm not in over my head. When I click submit on my form, nothing happens on my page, not in my SQL database where the info should be stored (double checked process form too). Here's the code if anyone's willing to help Javascript: $(document).ready(function() { $('#form').submit(function() { $.ajax({ url: "../process.php", type: "post", data: $(this).serialize() }); }); } HTML: <form name="contact" method="post" action="" id="form"> <span id="input"> <input type="text" name="first" maxlength="50" size="30" title="First Name" class="textbox"> <input type="text" name="last" maxlength="80" size="30" title="Last Name" class="textbox"> <input type="text" name="email" maxlength="80" size="30" title="Email" class="textbox"> <textarea name="request" maxlength="1000" cols="25" rows="6" title="Request"></textarea> </span> <input type="submit" value="Submit" class="submit"> </form>

  • how can I cache a partial retrieved through link_to_remote in rails?

    - by Angela
    I use link_to_remote to pull the dynamic contents of a partial onto the page. It's basically a long row from a database of "todo's" for the day. So as the person goes through and checks them off, I want to show the updated list with a line through those that are finished. Currently, I end up needing to click on the link_to_remote again after an item is ticked off, but would like it to redirect back to the "cached" page of to-do's but with the one item lined through. How do I do that? Here is the main view: <% @campaigns.each do |campaign| %> <!--link_to_remote(name, options = {}, html_options = nil)--> <tr><td> <%= link_to_remote(campaign.name, :update => "campaign_todo", :url => {:action => "campaign_todo", :id => campaign.id } ) %> </td></tr> <% end %> </table> <div id="campaign_todo"> </div> I'd like when the New/Create actions are done to go back to the page that redirected it there.

  • [Zend Framework] Forms and success output

    Well, It's a beginer's question but I really don't know what is the best way. I have a basic CRUD (Create, Retrieve, Update and Delete) in my project and I'd like to output some message if succeded or not in a div inside the same page. So, basically, I have a form which action is setted to the same page and I have a div #statusDiv below this same form which I'd like to output something like Register included with success. What is the best way for doing this? Set a flag in the controller $this->view->flagStatus = 'message' then call it in the view? Just to make it more clear. It's my code: //IndexController.php indexAction() ... //Check if there's submitted data if ($this->getRequest()->isPost()) { ... $registries->insert($data); $this->view->flagStatus = 'message'; $this->_redirect('/'); } Then my view: .... <?php if ($this->flagStatus) { ?> <div id="divStatus" class="success span-5" style="display: none;"> <?php echo $this->flagStatus; ?> </div> <?php } ?> ....

  • Very weird jquery/json problem...

    - by Scarface
    Hey guys I have finally located the cause of this problem...I just have no idea how to fix it and why it is happening. I have a jquery getjson function and it returns 0 results every 2-5 clicks on new topics or refreshes. For some reason if I change my query to sort results by ASC it always returns results and much quicker, but this poses a problem since I need results by DESC. If anyone has any ideas, I would greatly appreciate it because I am dumbfounded at this point. Here is my query but I need it by DESC SELECT time, user, message FROM comments WHERE topic_id='$topic_id' ORDER BY time ASC LIMIT 10 $.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < json.length; i++) { $('#comment-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } } }); I return results like so while($row = mysql_fetch_array($res)){ $data[] = $row; } $out = json_encode($data); print $out;

  • How do I code a tree of objects in Haskell with pointers to parent and children?

    - by axilmar
    I've got the following problem: I have a tree of objects of different classes where an action in the child class invalidates the parent. In imperative languages, it is trivial to do. For example, in Java: public class A { private List<B> m_children = new LinkedList<B>(); private boolean m_valid = true; public void invalidate() { m_valid = false; } public void addChild(B child) { m_children.add(child); child.m_parent = this; } } public class B { public A m_parent = null; private int m_data = 0; public void setData(int data) { m_data = 0; m_parent.invalidate(); } } public class Main { public static void main(String[] args) { A a = new A(); B b = new B(); b.setData(0); //invalidates A } } How do I do the above in Haskell? I cannot wrap my mind around this, since once I construct an object in Haskell, it cannot be changed. I would be much obliged if the relevant Haskell code is posted.

  • Accessing global variables in a flash[:notice]

    - by Trip
    This is deals_controller.rb. And it works like this, except two things. Not sure how to call Deal.count to add in my flash[:notice] . I get the hunch that its not calling something global. I need that contional statement back, as I'm pretty sure its responsible for actually adding the new @deal . So I assume my syntax is off. Do note, I added an extra 'end' when I uncomment this block. def create -# This will use the disclaimer_ids submitted from the check boxes in the view -# to add/delete deal.disclaimers entries to matched the list of checked boxes. @deal = Deal.new(params[:deal]) -# <------I Need this commented out IF statement back ------- -#if @deal.valid? && @organization.deals << @deal flash[:notice] = 'Your promotion is published! You may find it in the number 1 position of our #{deal.count} previously posted promotions. To see your promotion, click here."' respond_to do |format| format.html { redirect_to organization_deals_path(@organization) } format.js -# I Need this IF Statement Back! -#else -#@disclaimers = Disclaimer.all -#render :action = 'new' end end Thanks!
