  • Select form children when multiple forms are present jQuery

    - by afreeland
    I am dealing with a webpage that has multiple forms..some basic HTML forms and some AJAX forms. I have a created validation for inputs, let me give an example...if an input has a class="required" whenever a submit button is pressed if any required classes are empty then the form doesnt submit. Which works great...until you have multiple forms with required fields that dont apply to the section your submitting. I am able to find the closest form $(this).closest("form") and it gets me the form element properly, I then need to be able to loop only through the children of that form. I have tried: .children(':input'), .find('input') and honestly to many to list. Here is the code for when a button is selected $('#formSubmit').click(function (e) { var submit = true; var form = $(this).closest("form"); var formID = $(form).attr("id"); e.preventDefault(); $(form).children(":input").each(function () { if ($('#ERROR').length > 0) { submit = false; alert("Please fix errors to continue"); } $('.required').each(function () { if ($(this).val() == "" || $(this).val() == undefined) { submit = false; $(this).css({ 'background-color': '#fef236' }); } }); }); if (submit == true) { this.form.submit(); } }); //End of #formSubmit Also of interest I have started creating forms with ids that are GUID's so they will be unique and allow me to target things without any issues, just wanted to throw that out there if it can help lead to a solution I appreciate any help =)

  • How do you deal with breaking changes in a Rails migration?

    - by Adam Lassek
    Let's say I'm starting out with this model: class Location < ActiveRecord::Base attr_accessible :company_name, :location_name end Now I want to refactor one of the values into an associated model. class CreateCompanies < ActiveRecord::Migration def self.up create_table :companies do |t| t.string :name, :null => false t.timestamps end add_column :locations, :company_id, :integer, :null => false end def self.down drop_table :companies remove_column :locations, :company_id end end class Location < ActiveRecord::Base attr_accessible :location_name belongs_to :company end class Company < ActiveRecord::Base has_many :locations end This all works fine during development, since I'm doing everything a step at a time; but if I try deploying this to my staging environment, I run into trouble. The problem is that since my code has already changed to reflect the migration, it causes the environment to crash when it attempts to run the migration. Has anyone else dealt with this problem? Am I resigned to splitting my deployment up into multiple steps?

  • Tell me again why we need both .NET and Windows? Why can't Windows morph into the CLR?

    - by le dorfier
    The same way DOS morphed into Windows? We seem to have ended up supporting and developing for three platforms from Microsoft, and I'm not sure where the boundaries are supposed to lie. Why can't the benefits of the CLR (such as type safety, memory protection, etc.) be built into Windows itself? Or into the browser? Why an entirely other virtual machine? (How may levels of virtual machine indirection are we dealing with now? We just added Silverlight - and before that Flash - running inside the Browser running inside maybe a VM install...) I can see raw Windows for servers, but why couldn't there be a CLR for workstations talking directly to the hardware (or at least not the whole Windows legacy ball and chain)? (ooppp - I've got two questions here. Let's make this - why can't .net be built into Windows? I understand about backward compatibility - but the safety of what's in .NET could be at least optionally in Windows itself, couldn't it? It would just be yet another of many sets of APIs?) Factoid - I recall that one of the competitor architectures selling against MS-DOS on the IBM PC was UCSD-pascal runtime - a VM.

  • Moq basic questions

    - by devoured elysium
    I made the following test for my class: var mock = new Mock<IRandomNumberGenerator>(); mock.Setup(framework => framework.Generate(0, 50)) .Returns(7.0); var rnac = new RandomNumberAverageCounter(mock.Object, 1, 100); rnac.Run(); double result = rnac.GetAverage(); Assert.AreEqual(result, 7.0, 0.1); The problem here was that I changed my mind about what range of values Generate(int min, int max) would use. So in Mock.Setup() I defined the range as from 0 to 50 while later I actually called the Generate() method with a range from 1 to 100. I ran the test and it failed. I know that that is what it's supposed to happen but I was left wondering if isn't there a way to launch an exception or throw in a message when trying to run the method with wrong params. Also, if I want to run this Generate() method 10 times with different values (let's say, from 1 to 10), will I have to make 10 mock setups or something, or is there a special method for it? The best I could think of is this (which isn't bad, I'm just asking if there is other better way): for (int i = 1; i < 10; ++i) { mock.Setup(framework => framework.Generate(1, 100)) .Returns((double)i); }

  • counter_cache not updating on the model after save

    - by sehnsucht
    I am using a counter_cache to let MySQL do some of the bookkeeping for me: class Container has_many :items end class Item belongs_to :container, :counter_cache => true end Now, if I do this: container = Container.find(57) item = Item.new item.container = container item.save in the SQL log there will be an INSERT followed by something like: UPDATE `containers` SET `items_count` = COALESCE(`items_count`, 0) + 1 WHERE `containers`.`id` = 57 which is what I expected it to do. However, the container[:items_count] will be stale! ...unless I container.reload to pick up the updated value. Which in my mind sort of defeats part of the purpose of using the :counter_cache in favor of a custom built one, especially since I may not actually want a reload before I try to access the items_count attribute. (My models are pretty code-heavy because of the nature of the domain logic, so I sometimes have to save and create multiple things in one controller call.) I understand I can tinker with callbacks myself but this seems to me a fairly basic expectation of the simple feature. Again, if I have to write additional code to make it fully work, it might as well be easier to implement a custom counter. What am I doing/assuming wrong?

  • C# Script to get modified date from URL directory

    - by Jynx
    Hello, I am fairly new to C# and was hoping for some assistance. I currently use Visual Studio 2008. What I am wanting to do is the following: I have a server (\backupserv) that runs a RoboCopy script nightly to backup directories from 18 other servers. These directories are then copied down to \backup in directories of their own: Example: It copies down "Dir1", "Dir2", and "Dir3" from Server1 into \backupserv\backups\Server1 into their own directories (\backupserv\backups\Server1\Dir1, \backupserv\backups\Server1\Dir2, and \backupserv\backups\Server1\Dir3). It does this for all 18 servers nightly between 12am and 6am. The RoboCopy runs via schedule task. A log file is created in \backupserv\backups\log and is named server1-dir1.log, server1-dir2.log, etc. What I am wanting to accomplish in C# is the ability to have a 'report' showing the modified date of each text log file. To do this I need to browse the \backupserv\backups\log directory, determine the modified date, and have a report displayed (prefer HTML if possible). Along with the modified date I will be showing more information, but that is later. Again, I am fairly new to C#, so, please be gentle. I was referred here by another programmer, and was told I would get some assistance. Thanks in advance. If I have missed any detail please let me know and I will do my best to answer.

    - by Katyal
    I'm using jqueryUI for tabs on a page. I initialize it like below: $("#tabs").tabs(); <div id="tabs"> <ul> <li><a href="#tabs-4">Part A</a></li> <li><a href="#tabs-2">Part B</a></li> <li><a href="#tabs-5">Part C</a></li> </ul> <div id="tabs-4"> ..... </div> <div id="tabs-2"> .... </div> <div id="tabs-5"> .... </div> </div> I have 2 questions. How do I set the tab to be custom. say I want second tab to be shown first. $('#tabs').tabs(2) does not work. i got that from this link Let say I click on a button inside tab1. Clicking on the button takes control back to an action and then control comes back to this page. When the control comes back...then is it possible to set a custom tab?. For example. in tab 1 I click something...go back to the action...and then I want to come back to tab 2.

    hi every one, i am facing a big problem right now. I have a html table in each row i have a button called edit allowing user to relod the form with parameter that he has selected. for this i define a hidden type to get the id of the record in database to access to various colonne and to refresh the form with those parameters. My challenge now is how to get the right id in every click on the edit button to let me after to get the right record and to update it in the data base. I am preceeding like the following: retour.append("<td style=border-right:#FFF bordercolor=#FFFFFF>"); retour.append("<input type=\"hidden\" id=\"id_"+nomTab+"_"+compteur+"\" value=\""+object.getIdDailyTimeSheet()+"\" name=\"hd"+compteur+"\" />"); retour.append("<button id=edit name=edit type=button onClick= editarow()>"); retour.append("<img src=edit.gif />"); retour.append("</button>"); retour.append("</td>"); i realise the submit in javascript and i want to get the idDailyTimesheet everyonce the user click the submit button. thanks for help.

  • strange doctrine update problem

    - by larryzhao
    Hi, guys, I have a simple table like following: class SnookerCurrentInfo extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('current_frame_id', 'integer', 4, array('notnull' => 'false')); $this->hasColumn('current_player_id', 'integer', 4, array('notnull' => 'false')); $this->hasColumn('current_score1', 'integer', 4, array('notnull' => 'false')); $this->hasColumn('current_score2', 'integer', 4, array('notnull' => 'false')); } public function setUp(){ $this->setTableName('snooker_current_info'); } } and I would like to keep only one entry in this table. So every time the value is changed I read the entry with id = 1 out and change the object and execute save. like the following: $info = Doctrine::getTable('SnookerCurrentInfo')->find(1); $info->current_frame_id = $jsonInfo['current_frame_id']; $info->current_player_id = $jsonInfo['current_player_id']; $info->current_score1 = $jsonInfo['current_score1']; $info->current_score2 = $jsonInfo['current_score2']; $info->save(); but the strange thing is, I try to make it clear. Let's say at first, the entry is (30, 1, 1, 0) and I switch player, so update the entry to (30, 2, 1, 0). and I switch the player back again, so the entry should be updated to (30, 1, 1, 0), but this is not affected to the database!! In the database, the entry still remains as (30, 2, 1, 0)!!!! But if after (30, 2, 1, 0), I update the score to (30, 2, 1, 1) and then switch the player back (30, 1, 1, 1) then this is ok. What's that? How should I deal with it? Thanks for a lot helping, really urgent!!

  • rails route question

    - by badnaam
    I am trying to build a search functionality which at a high level works like this. 1 - I have a Search model, controller with a search_set action and search views/partial to render the search. 2 - At the home page a serach form is loaded with an empty search object or a search object initialized with session[:search] (which contains user search preferences, zip code, proximity, sort order, per page etc). This form has a post(:put) action to search_set. 3 - When a registered user performs a set the params of the search form are collected and a search record is saved against that user. If a unregistered user performs a search then the search set action simply stores the params in the session[:search]. In either case, the search is executed with the given params and the results are displayed. At this point the url of in the location bar is something like.. http://localhost:3000/searches/search_set?stype=1 At this point if the user simply hits enter on the location bar, I get an error that says "No action responded to show" I am guessing because the URL contains search_set which uses a put method and even though I have a search_show (:get) action (which simply reruns the search in the session or saved in the database) does not get called. How can I handle this situation where I can route a user hitting enter into the location bar to a get method? If this does not explain the problem , please let me know I can share more details/code etc. Thanks!

  • How do I get a thumbnail or saveable path from UIImagePickerController to use for a UIImageView?

    - by viperacr99
    Could somebody please explain or show some sample code of how I can use get a thumbnail to be put into a UIImageView after the user selects a photo with UIImagePickerController? Let's say I want to set a thumbnail as the image of a table view cell. When the user presses the cell, the image picker is shown and the user selects an image that is already on their device. I also want to save the path to that thumbnail so that the next time the view is displayed, the proper thumbnail can be shown. I am able to display an image picker and my delegate get's the chosen image correctly, but I want the path to the thumbnail, and I want to load the thumbnail using that path (i.e. I want to save the path). I've searched for hours today and haven't figured this out. Perhaps I'm not understanding ALAsset, or maybe it is something else, but I can't find any examples that are helping me. I have never used the image picker or ALAsset before now, so I'm completely new at this.

  • Fastest container or algorithm for unique reusable ids in C++

    - by gman
    I have a need for unique reusable ids. The user can choose his own ids or he can ask for a free one. The API is basically class IdManager { public: int AllocateId(); // Allocates an id void FreeId(int id); // Frees an id so it can be used again bool MarkAsUsed(int id); // Let's the user register an id. // returns false if the id was already used. }; Assume ids happen to start at 1 and progress, 2, 3, etc. This is not a requirement, just to help illustrate. IdManager mgr; mgr.MarkAsUsed(3); printf ("%d\n", mgr.AllocateId()); printf ("%d\n", mgr.AllocateId()); printf ("%d\n", mgr.AllocateId()); Would print 1 2 4 Because id 3 has already been declared used. What's the best container / algorithm to both remember which ids are used AND find a free id? If you want to know the a specific use case, OpenGL's glGenTextures, glBindTexture and glDeleteTextures are equivalent to AllocateId, MarkAsUsed and FreeId

  • Passing huge amounts of data as an hexadecimal (0x123AB...) parameter of a clr stored procedure in s

    - by user193655
    I post this question has followup of This question, since the thread is not recieving more answers. I'm trying to understand if it is possible to pass as a parameter of a CLR stored procedure a large amount of data as "0x5352532F...". This is to avoid to send the data directly to the CLR stored procedure, instead of sending ti to a temporary DB field and from there passing it as varbinary(max) parmeter to the CLR stored procedure. I have a triple question: 1) is it possible, if yes how? Let's say i want to pass a pdf file to the CLR stored procedure (not the path, the full bits that make up the file). Something like: exec MyCLRStoredProcs.dbo.insertfile @file_remote_path ='c:\temp\test_file.txt' , @file_contents=0x4D5A90000300000004000.... --(this long list is the file content) where insertfile is a stored proc that writes to the server path (at file_remote_path) the binary data I pass as (file_contents). 2) is it there corruption risk of adopting this approach (or it is the same approach that sql server uses behind the scenes)? 3) how to convert the content of a file into the "0x23423..." hexadecimal representation

  • Memory Barrier by lock statement

    - by jalalaldeen
    I read recently about memory barrier and the reordaring issue and now I have some confusion about it. Let us have a following senario: private object _object1 = null; private object _object2 = null; private bool _usingObject1 = false; private object MyObject { get { if (_usingObject1) { return _object1; } else { return _object2; } } set { if (_usingObject1) { _object1 = value; } else { _object2 = value; } } } private void Update() { _usingMethod1 = true; SomeProperty = FooMethod(); //.. _usingMethod1 = false; } 1- At Update method; is it always _usingMethod1 = true statement excecuted before getting or setting the property? or due reordaring issue we can not garantee that? 2- Should we use volitle like. private volitle bool _usingMethod1 = false; 3- If we use lock; can we garantee then every statement within the lock will be excecuted in order like: private void FooMethod() { object locker = new object(); lock (locker) { x = 1; y = a; i++; } } Thanks in advanced..

  • Addiing captions above images in wordpress

    - by jacob
    So I added some code in my css and there are boxes that appear over every image that is attached to a post. I've wanted to number the images and show the image number in the box(1...n). I have this in my functions.php function count_images(){ global $post; $thePostID = $post-ID; $parameters = array( 'post_type' = 'attachment', 'post_parent' = $thePostID, 'post_mime_type' = 'image'); $attachments = get_children($parameters); $content = count($attachments); return $content; } add_filter('the_content','count_images'); function caption_image_callback($matches) { $c = count_images(); for ($i=1; $i <= $c; $i++) { if (is_single()) { return ''.$i.' '; } else { return ''; } } } function caption_image($post_body_content) { $post_body_content = preg_replace_callback("||","caption_image_callback",$post_body_content); return $post_body_content; } if ( current_user_can('edit_plugins') ) { add_filter('the_content', 'caption_image'); } If I run only count_images it will show the correct number of attached images to a post(let's say 15). But for some reason the number that is shown in the boxes over the images is always 1. I've seen this done on several blogs with just php so there has to be a way(even if I have to change my whole code). PS: I had to leave spaces in some places

  • XML in Authorware 7.01

    - by Mikael
    Let me explain the setup that is being used. Right now I have an authorware program which loads an ocx control. This control receives data in the form on an XML string. This part is working properly. However I need parse this XML string in authorware and have not been successful. I have been trying to use the XMLParser Xtra. The documentation listed here shows how to create a new XMLParser object and then shows how to call the object but never explains how to link the Parser to a XML file or XML string. The information I have been using can be found here https://www.adobe.com/livedocs/authorware/7/using_aw_en/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Using_Authorware_7&file=09_va110.htm#224295 I need more information on how to Parse XML with this function or if there is another way to do this in Authorware. As a side note the documentation says it cannot create or append to XML, I will need to do this also inside of Authorware. Is this possible and if so, how?

  • Static variable definition order in c++

    - by rafeeq
    Hi i have a class tools which has static variable std::vector m_tools. Can i insert the values into the static variable from Global scope of other classes defined in other files. Example: tools.h File class Tools { public: static std::vector<std::vector> m_tools; void print() { for(int i=0 i< m_tools.size() ; i++) std::cout<<"Tools initialized :"<< m_tools[i]; } } tools.cpp File std::vector<std::vector> Tools::m_tools; //Definition Using register class constructor for inserting the new string into static variable. class Register { public: Register(std::string str) { Tools::m_tools.pushback(str); } }; Different class which inserts the string to static variable in static variable first_tool.cpp //Global scope declare global register variable Register a("first_tool"); //////// second_tool.cpp //Global scope declare global register variable Register a("second_tool"); Main.cpp void main() { Tools abc; abc.print(); } Will this work? In the above example on only one string is getting inserted in to the static list. Problem look like "in Global scope it tries to insert the element before the definition is done" Please let me know is there any way to set the static definiton priority? Or is there any alternative way of doing the same.

  • ObjectDataSource firing twice, or on its own

    - by LoveMeSomeCode
    Can someone explain exactly how/when an ObjectDataSource fires? I have an ASP.NET page, with a GridView, which is referencing an ODS. I put a breakpoint in the method the ODS is using, and noticed it was firing twice. I looked into the code and the answer seemed obvious at first. I had Page_Load() { if(!Page.IsPostBack) { MethodA(); MethodB(); } } where MethodA and MethodB were both eventually calling gv.DataBind(). This made sense because I assume that each call to GridView.DataBind() would result in asking the ODS for data, and therefore running my data access method. The weird thing is that when comment out the call to MethodA, it still fires twice. Checking the call stack shows the method being run first as a result of MethodB, and then again, with no trail except [External Code]. This mystery load does not happen when I let MethodA and MethodB both execute. Any idea what's going on here? Any idea what other code I might have that is asking the ODS for data? I'm starting to think all these 'no code' data controls are more obfuscation and BS than they're worth.

  • for loop vs std::for_each with lambda

    - by Andrey
    Let's consider a template function written in C++11 which iterates over a container. Please exclude from consideration the range loop syntax because it is not yet supported by the compiler I'm working with. template <typename Container> void DoSomething(const Container& i_container) { // Option #1 for (auto it = std::begin(i_container); it != std::end(i_container); ++it) { // do something with *it } // Option #2 std::for_each(std::begin(i_container), std::end(i_container), [] (typename Container::const_reference element) { // do something with element }); } What are pros/cons of for loop vs std::for_each in terms of: a) performance? (I don't expect any difference) b) readability and maintainability? Here I see many disadvantages of for_each. It wouldn't accept a c-style array while the loop would. The declaration of the lambda formal parameter is so verbose, not possible to use auto there. It is not possible to break out of for_each. In pre- C++11 days arguments against for were a need of specifying the type for the iterator (doesn't hold any more) and an easy possibility of mistyping the loop condition (I've never done such mistake in 10 years). As a conclusion, my thoughts about for_each contradict the common opinion. What am I missing here?

  • Why does this sql statement keep saying it is a boolean and not a parameter? (php/Mysql)

    - by ggfan
    In this statement, I am trying to see if there if the latest posting in the database that has the exact same title, price, city, state, detail. If there is, then it would say to the user that the exact post has been already made; if not then insert the posting into the dbc. (This is one type of check so that users can't accidentally post twice. This may not be the best check, but this statement error is annoying me, so I want it to work :)) Why won't this sql work?

  • What db fits me?

    - by afvasd
    Dear Everyone I am currently using mysql. I am finding that my schema is getting incredibly complicated. I seek to find a new db that will suit my needs: Let's assume I am building a news aggregrator (which collects news from multiple website). I then run algorithms to determine if two news from different sites are actually referring to the same topic. I run this algorithm to cluster news together. The relationship is depicted below: cluster \--news1 \--word1 \--word2 \--news2 \--word3 \--news3 \--word1 \--word3 And then I will apply some magic and determine the importance of each word. Summing all the importance of each word gives me the importance of a news article. Summing the importance of each news article gives me the importance of a cluster. Note that above cluster there are also subgroups( like split by region etc), and categories (like sports, etc) which I have to determine the importance of that in a particular day per se. I have used views in the past to do so, but I realized that views are very slow. So i will normally do an insert into an actual table and index them for better performance. As you can see this leads to multiple tables derived like (cluster, importance), (news, importance), (words, importance) etc which can get pretty messy. Also the "importance" metric will change. It has become increasingly difficult to alter tables, update data (which I am using TRUNCATE TABLE) and then inserting from null. I am currently looking into something schemaless like Mongodb. I do not need distributedness. I would very much want something that is reasonably fast (which can be indexed) and something that is a lot more flexible that traditional RDMBS. Also, I need something that has some kind of ORM because I personally like ORM a lot. I am currently using sqlalchemy Please help!

  • determining the starting speed for an accelerated animation (in flash/actionscript but it's a math question)

    - by vulkanino
    This question burns my brain. I have an object on a plane, but for the sake of simplicity let's work just on a single dimension, thus the object has a starting position xs. I know the ending position xe. The object has to move from starting to ending position with an accelerated (acceleration=a) movement. I know the velocity the object has to have at the ending position (=ve). In my special case the ending speed is zero, but of course I need a general formula. The only unknown is the starting velocity vs. The objects starts with vs in xs and ends with ve in xe, moving along a space x with an acceleration a in a time t. Since I'm working with flash, space is expressed in pixels, time is expressed in frames (but you can reason in terms of seconds, it's easy to convert knowing the frames-per-second). In the animation loop (think onEnterFrame) I compute the new velocity and the new position with (a=0.4 for example): vx *= a (same for vy) x += vx (same for y) I want the entire animation to last, say, 2 seconds, which at 30 fps is 60 frames. Now you know that in 60 frames my object has to move from xs to xe with a constant deceleration so that the ending speed is 0. How do I compute the starting speed vs? Maybe there's a simpler way to do this in Flash, but I am now interested in the math/physics behind this.

  • Textbox time validations (javascript)

    - by unos
    I have a textbox in which user can enter time (eg- 01:00) and also a drop down box for entering AM/PM fields. (Since the AM/PM field is used, 12-hour time format is used.) The text box allows a max entry of 5 chars only (eg - 01:00). Pls let me know how I can set the 3rd char as a default -colon : , so that the user simply has to enter only the time. How to check if the time entered by the user is numeric or not?. Autocompletion feature : for eg, if user enters 1 then it would automatically be set to 01:00 Javascript Validations for 12-hour format. Eg: if user enters 13:00 then it should change to 01:00 How can I append the text box time values with the am/pm value selected in the drop down box?. Once the values are appended, automatically populate another text box (text box 2) with the result. Eg: 01:00 + pm should be set as 01:00p in the new text box (text box 2). Any help would be appreciated.

  • Creating 3rd party library in Android. Need suggestions!!

    - by Lalith
    Hello all, I am planning to create a 3rd party library for android application developers. Also the main concern is I do not want the users to make many changes to their code base. The following are the main things I want to clarify before diving into the project. 1) I want to attach my own event handlers dynamically to the application. As per above limitations I mentioned, I cannot make users put the relevant code in their handlers as I need to support existing applications as well. I found out that we cannot attach more than one event handler per one listener. For example Button.setOnclickListener(somelistener) .. will set one listener. In traditional desktop applications we can add more than one handlers but here if I do one more Button.setOnclickListener(someOtherListener) this one overwrites the previous listener. Is there any way I can attach my own listener along with application's existing listeners dynamically? Also is it really not supported on android yet? 2) Is there any 3rd party alternative that exists already that monitors user's interactions in androidi? 3) If this is not supported now are there any future plans to support this feature? Please let me know about this as I did not get much feedback on Stackoverflow. Any suggestions and workarounds would really help me continue with this project. Regards, Lalith
