  • Firefox handles xxx.submit(), Safari doesn't ... what can be done?

    - by Prairiedogg
    I'm trying to make a pull down menu post a form when the user selects (releases the mouse) on one of the options from the menu. This code works fine in FF but Safari, for some reason, doesn't submit the form. I re-wrote the code using jquery to see if jquery's .submit() implementation handled the browser quirks better. Same result, works in FF doesn't work in safari. The following snippets are from the same page, which has some django template language mixed in. Here's the vanilla js attempt: function formSubmit(lang) { if (lang != '{{ LANGUAGE_CODE }}') { document.getElementById("setlang_form").submit(); } } Here's the jquery attempt: $(document).ready(function() { $('#lang_submit').hide() $('#setlang_form option').mouseup(function () { if ($(this).attr('value') != '{{ LANGUAGE_CODE }}') { $('#setlang_form').submit() } }); }); and here's the form: <form id="setlang_form" method="post" action="{% url django.views.i18n.set_language %}"> <fieldset> <select name="language"> {% for lang in interface_languages %} <option value="{{ lang.code }}" onmouseup="formSubmit('{{ lang.name }}')" {% ifequal lang.code LANGUAGE_CODE %}selected="selected"{% endifequal %}>{{ lang.name }}</option> {% endfor %} </select> </fieldset> </form> My question is, how can I get this working in Safari?

  • How to efficiently implement a strategy pattern with spring ?

    - by Anth0
    I have a web application developped in J2EE 1.5 with Spring framework. Application contains "dashboards" which are simple pages where a bunch of information are regrouped and where user can modify some status. Managers want me to add a logging system in database for three of theses dashboards. Each dashboard has different information but the log should be traced by date and user's login. What I'd like to do is to implement the Strategy pattern kind of like this : interface DashboardLog { void createLog(String login, Date now); } // Implementation for one dashboard class PrintDashboardLog implements DashboardLog { Integer docId; String status; void createLog(String login, Date now){ // Some code } } class DashboardsManager { DashboardLog logger; String login; Date now; void createLog(){ logger.log(login,now); } } class UpdateDocAction{ DashboardsManager dbManager; void updateSomeField(){ // Some action // Now it's time to log dbManagers.setLogger = new PrintDashboardLog(docId, status); dbManagers.createLog(); } } Is it "correct" (good practice, performance, ...) to do it this way ? Is there a better way ? Note :I did not write basic stuff like constructors and getter/setter.

  • RPC command to initiate a software install

    - by ericmayo
    I was recently working with a product from Symantech called Norton EndPoint protection. It consists of a server console application and a deployment application and I would like to incorporate their deployment method into a future version of one of my products. The deployment application allows you to select computer workstations running Win2K, WinXP, or Win7. The selection of workstations is provided from either AD (Active Directory) or NT Domain (WINs/DNS NetBIOS lookup). From the list, one can click and choose which workstations to deploy the end point software which is Symantech's virus & spyware protection suite. Then, after selecting which workstations should receive the package, the software copies the setup.exe program to each workstation (presumable over the administrative share \pcname\c$) and then commands the workstation to execute setup.exe resulting in the workstation installing the software. I really like how their product works but not sure what they are doing to accomplish all the steps. I've not done any deep investigations into this such as sniffing the network, etc... and wanted to check here to see if anyone is familiar with what I'm talking about and if you know how it's accomplished or have ideas how it could be accomplished. My thinking is that they are using the admin share to copy the software to the selected workstations and then issuing an RPC call to command the workstation to do the install. What's interesting is that the workstations do this without any of the logged in users knowing what's going on until the very end where a reboot is necessary. At which point, the user gets a pop-up asking to reboot now or later, etc... My hunch is that the setup.exe program is popping this message. To the point: I'm looking to find out the mechanism by which one Windows based machine can tell another to do some action or run some program. My programming language is C/C++ Any thoughts/suggestions appreciated.

  • How does asp.net MVC remember my false values on postback?

    - by Michel
    Hi, This is working, but how??? I have a controller action for a post: [AcceptVerbs(HttpVerbs.Post )] public ActionResult Edit(Person person) { bool isvalid = ModelState.IsValid; etc. The Person object has a property BirthDate, type DateTime. When i enter some invalid data in the form, say 'blabla' which is obvious not a valid Datetime, it fills all the (other) Person properties with the correct data and the BirthDate property with a new blank DateTime. The bool isvalid has the value 'false'. So far so good. Then i do this: return View(p); and in the view i have this: <%= Html.TextBox("BirthDate", String.Format("{0:g}", Model.BirthDate)) %> <%= Html.ValidationMessage("BirthDate", "*") %> Ant there it comes: i EXPECTED the model to contain the new, blank DateTime because i didn't put any new data in. Second, when the View displays something, it must be a DateTime, because Model.BirthDate can't hold anything but a DateTime. But to my surprise, it shows a textbox with the 'blabla' value! (and the red * behind it) Which ofcourse is nice because the user can seee what he typed wrong, but how can that (blabla)string be transferred to the View in a DateTime field?

  • How do I convert a simple ruby flashcard program into a ROR app?

    - by Mark Wilbur
    What I'm trying to do is make a basic flashcard app on rails. At this point, all I'm looking for is the functionality to iterate through a list of flashcards, quiz the user and let the user know if they were right or not. In ruby, it didn't take me long to write: class Card attr_accessor :answer, :question def initialize(answer = "", question="") @answer = answer @question = question end def quiz puts "What does #@question mean?" answer = gets.chomp if answer == @answer puts "Right" return true else puts "Wrong" return answer end end end class Cardlist attr_accessor :Cards def initialize(Cards = []) @Cards = Cards end def quiz Cards.each do |w| w.quiz end end end The problem I'm having with rails is figuring out where to put the logic to loop through all the cards in the list. I've made models specifying that Card belongs_to cardlist and that Cardlist has_many cards. I know application logic should go in the controller, but if I were to make a "quiz" action for my Cardlist controller, how would I make it iterate through all the cards? After each "quiz" page generated, I'd need to get an answer back from the user, respond (maybe flash) whether it was right or not and then continue onto the next question. Would any of that logic have to go into the view in order to make sure it's sending back the user inputted answers to the controller?

  • Simple search form passing the searched string through GET

And that's what I'd like to get! Could anybody help me on this?

  • Loading views dynamically

    - by Dan
    Case 1: I have created View-based sample application and tried execute below code. When I press on "Job List" button it should load another view having "Back Btn" on it. In test function, if I use [self.navigationController pushViewController:jbc animated:YES]; nothing gets loaded, but if I use [self presentModalViewController:jbc animated:YES]; it loads another view haveing "Back Btn" on it. Case 2: I did create another Navigation Based Applicaton and used [self.navigationController pushViewController:jbc animated:YES]; it worked as I wanted. Can someone please explain why it was not working in Case 1. Does it has something to do with type of project that is selected? @interface MWViewController : UIViewController { } -(void) test; @end @interface JobViewCtrl : UIViewController { } @end @implementation MWViewController (void)viewDidLoad { UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Job List!" forState:UIControlStateNormal]; [btn addTarget:self action:@selector(test) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:btn]; [super viewDidLoad]; } -(void) test { JobViewCtrl* jbc = [[JobViewCtrl alloc] init]; [self.navigationController pushViewController:jbc animated:YES]; //[self presentModalViewController:jbc animated:YES]; [jbc release]; } (void)dealloc { [super dealloc]; } @end @implementation JobViewCtrl -(void) loadView { self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.view.backgroundColor = [UIColor grayColor]; UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Back Btn!" forState:UIControlStateNormal]; [self.view addSubview:btn]; } @end

  • Unable to diligently close the excel process running in memory

    - by NewAutoUser
    I have developed a VB.Net code for retrieving data from excel file .I load this data in one form and update it back in excel after making necessary modifications in data. This complete flow works fine but most of the times I have observed that even if I close the form; the already loaded excel process does not get closed properly. I tried all possible ways to close it but could not be able to resolve the issue. Find below code which I am using for connecting to excel and let me know if any other approach I may need to follow to resolve this issue. Note: I do not want to kill the excel process as it will kill other instances of the excel Dim connectionString As String connectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & ExcelFilePath & "; Extended Properties=excel 8.0; Persist Security Info=False" excelSheetConnection = New ADODB.Connection If excelSheetConnection.State = 1 Then excelSheetConnection.Close() excelSheetConnection.Open(connectionString) objRsExcelSheet = New ADODB.Recordset If objRsExcelSheet.State = 1 Then objRsExcelSheet.Close() Try If TestID = "" Then objRsExcelSheet.Open("Select * from [" & ActiveSheet & "$]", excelSheetConnection, 1, 1) Else objRsExcelSheet.Open("Select Test_ID,Test_Description,Expected_Result,Type,UI_Element,Action,Data,Risk from [" & ActiveSheet & "$] WHERE TEST_Id LIKE '" & TestID & ".%'", excelSheetConnection, 1, 1) End If getExcelData = objRsExcelSheet Catch errObj As System.Runtime.InteropServices.COMException MsgBox(errObj.Message, , errObj.Source) Return Nothing End Try excelSheetConnection = Nothing objRsExcelSheet = Nothing

  • Problem in DataBinding an Enum using dictionary approach to a combobox in WPF.

    - by Ashish Ashu
    I have a Dictionary which is binded to a combobox. I have used dictionary to provide spaces in enum. public enum Option {Enter_Value, Select_Value}; Dictionary<Option,string> Options; <ComboBox x:Name="optionComboBox" SelectionChanged="optionComboBox_SelectionChanged" SelectedValuePath="Key" DisplayMemberPath="Value" SelectedItem="{Binding Path = SelectedOption}" ItemsSource="{Binding Path = Options}" /> This works fine. My queries: 1. I am not able to set the initial value to a combo box. In above XAML snippet the line SelectedItem="{Binding Path = SelectedOption}" is not working. I have declared SelectOption in my viewmodel. This is of type string and I have intialized this string value in my view model as below: SelectedOption = Options[Options.Enter_Value].ToString(); 2. The combobox is binded to datadictionary which have two options first is "Enter_value" and second is "Select_value" which is actually Option enum. Based on the Option enum value I want to perform different action. For example if option is equal to option.Enter_value then Combo box becomes editable and user can enter the numeric value in it. if option is equal to option.Select_value value then the value comes from the database and the combo box becomes read only and shows the fetched value from the database. Please Help!!

  • Is there a better way to keep track of session variable creation/access throughout different pages?

    - by Brandon
    Here's what I am working on. At my website I have multiple processes with each one containing multiple steps. Now in one of the processes, there is an error checking routine executed before proceeding to the next step of that process. A session var is set indicating the error status and it will either redirect back to the referrer or display the next page's contents. Now this kind of functionality, I believe, is common throughout web development. The issue that is occurring is that session vars are left around and are not being cleaned up properly. At times this introduces undesired behavior. My website is growing and I find that I am requiring more and more session vars to keep track of different system and error states. So I was thinking about creating a kind of "session variable keeper" to keep track of session var usage. The idea is fairly simple. It will have the notion of a context (e.g. registration process) and allow access to a predefined set of session vars within that context. In addition, the var and context will be paired with an action to proceed to some form of event handling. So if you haven't noticed I'm new to web development. Any thoughts or comments on the idea that I am proposing would be greatly appreciated. The back-end is written in PHP/MySQL.

  • Rails routing of a controller's functions query

    - by Jty.tan
    So I've got a Users controller, and it has (amongst others) a function called details. The idea is that a user can go to localhost:3000/user/:user_id/details and be able to view the details of :user_id. For example, I have a user called "tester". When I go to the uri: http://localhost:3000/users/tester/details I'd want the details function to be called up, to render the details view, and to display the information for the user tester. But instead I get an error saying that No action responded to tester. Actions: change_password, create, current_user, details, forgot_password, index, login_required, new, redirect_to_stored, show, and update_attributes And I understand that to basically mean that if I wanted to access details, I should really be using http://localhost:3000/users/details Except that that isn't really working either... .< That is instead bringing me to http://localhost:3000/users/details/registries (which is the default path that I'd stipulated for anybody trying to view users/:user_id, so again, that's working the way I wanted it to) Point is: Can anybody help and tell me how I can go about getting users/:user_id/details to work the way I want it to and display the details of :user_id? Thanks!

  • FireFox: strange behavior on submiting a form

    - by ilnur777
    Can anyone help with this strange form submiting in FireFox? So this form should be submitted after pushing "go to submit" button. There is an onclick event on the button that should submit form through JavaScript. In the form there is another button "test" without any onclick event. Following the script, the form should be submitted only after pushing the "go to submit" button, but it submits even pushing at "test" button. In the Internet Explorer it works well! But this stupid FireFox browser behaves different. Here is example of HTML page: <script> function func(){ document.form1.submit(); } </script> <form name="form1" method="post" action="somewhere.php"> <button>test</button> <input type="button" value="go to submit" onclick="func();"> </form> I have several buttons with <button onclick="...">option 1</button> options. I want to fix strange submiting a form in FireFox. Help please!

  • How to run perl script with a few arguments from php

  • form target iframe not working in IE7- in facebook fan tab

    - by greatcaesarsghost
    This issue is similar to the one discussed in this thread, only mine is in a Facebook fan page tab (FBML/FBJS). The fix described in the referenced question works fine outside of Facebook, but for whatever reason I can't get it to work in the posted FBJS. Here's a stripped down version of what I'm trying to do: <script type="text/javascript"> function doit() { document.getElementById('msg').setInnerXHTML('<iframe id="testframe" name="testframe" frameborder="0" />'); } </script> <div id="msg"></div> <form action="http://somesite.com/whatever.php" method="post" id="testform" name="testform" target="testframe"> <input type="text" id="txt1" name="txt1" /> <input type="submit" id="btn" name="btn" value="test" onclick="doit();" /> </form> -- This behaves as you'd expect in all browsers, except IE <= 7, where it opens a new window. IE's dev tool shows the iframe as having a 'submitName' attribute, but no 'name' attribute. Even by manually setting the name (document.getElementbyId('testframe').setName('testframe') fails to work the way it would outside of Facebook. Has anyone run into this same issue, and if so, is there any way around it? Thank you.

  • Why Backbone.js isn't binding my event

    - by Saif Bechan
    I have a router like this, as main entry point: window.AppRouter = Backbone.Router.extend({ routes: { '': 'login' }, login: function(){ userLoginView = new UserLoginView(); } }); var appRouter = new AppRouter; Backbone.history.start({pushState: true}); I have a model/collection/view like this: window.User = Backbone.Model.extend({}); window.Users = Backbone.Collection.extend({ model: User }); window.UserLoginView = Backbone.View.extend({ events: { 'click #login-button': 'loginAction' }, initialize: function(){ _.bindAll(this, 'render', 'loginAction'); }, loginAction: function(){ var uid = $("#login-username").val(); var pwd = $("#login-password").val(); var user = new User({uid:uid, pwd:pwd}); } }); And body of my HTML looks like this: <form action="#" method="POST" id="login-form"> <p> <label for="login-username">username</label> <input type="text" id="login-username" autofocus /> </p> <p> <label for="login-password">password</label> <input type="password" id="login-password" /> </p> <a id="login-button" href="#">Inloggen</a> </form> Note: The HTML comes from Node.js using express.js, should I maybe wait for a document ready event somewhere? Edit: I have tried this, create the view when ready, did not solve the problem. $(function(){ userLoginView = new UserLoginView(); });

  • iPhone or Android apps that use SMS based authentication?

    - by JSW
    What are some iPhone or Android applications that use SMS as their primary means of user authentication? I'm interested to see such apps in action. SMS-auth seems like a natural approach that is well-situated to mobile contexts. The basic workflow is: to sign up, a user provides a phone number; the app calls a backend webservice which generates a signed URL and sends it to the phone number via an SMS gateway; the user receives the SMS, clicks the link, and is thus verified and logged in. This results in a very strong user identity that is difficult to spoof yet fairly easy. It can be paired with a username or additional account attributes as needed for the product requirements. Despite the advantages, this does not seem to be in much use - hence my question. My initial assumption is that this is because products and users are wary of asking for / providing phone numbers, which users consider sensitive information. That said, I hope this becomes an increasingly more commonplace approach.

  • UITableViewRowAnimationBottom doesn't work for last row

    - by GendoIkari
    I've come across a very similar question here: Inserting row to end of table with UITableViewRowAnimationBottom doesn't animate., though no answers have been given. His code was also a little different than mine. I have an extremely simple example, built from the Navigation application template. NSMutableArray *items; - (void)viewDidLoad { [super viewDidLoad]; items = [[NSMutableArray array] retain]; self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addItem)] autorelease]; } - (void)addItem{ [items insertObject:@"new" atIndex:0]; [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:0 inSection:0]] withRowAnimation:UITableViewRowAnimationBottom]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return items.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [items objectAtIndex:indexPath.row]; return cell; } - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [items removeObjectAtIndex:indexPath.row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationBottom]; } } The problem is, when I either insert or delete the very last row in the table, the animation doesn't work at all; the row just appears or disappears instantly. This only happens with UITableViewRowAnimationBottom, but that's the animation that makes the most sense for creating or deleting table cells in this way. Is this a bug in Apple's framework? Or does it do this on purpose? Would it make sense to add an extra cell to the count, and then setup this cell so that it looks like it's not there at all, just to get around this behavior?
