• howto catch jQuery for multiple links but not all

  - by user247245

  I'm trying to dig into jQuery but would like some feedback on how to do things the best way, I have a list with items, which each contains a hidden div that should show upon click on it's parent, list div:ed item1 with link hidden div div:ed item2 with link hidden div .. My current solution is to trace the calling link by it's id and then reusing that ID for showing the correct hidden one: $(document).ready(function() { //jQ should only trigger on links with id="cmLinkINT" $("a").click(function() { //see if it's a comment request. var s = $(this).attr("id"); if (s.indexOf('cmLink') != -1) { //ok, it was a 'show'-link, get the id.. var j = s.substring(6); //ok, now I have the id i want to show (detailsINT) return false; } }); }); What's not clear to me is the best approach, Should I use id for requesting a or trace the id of the parent div. How to avoid that the code triggers on any link? Class? Thankful for any feedback, regards //t

• Refactoring Rspec specs

  - by Steve Weet

  I am trying to cleanup my specs as they are becoming extremely repetitive. I have the following spec describe "Countries API" do it "should render a country list" do co1 = Factory(:country) co2 = Factory(:country) result = invoke :GetCountryList, "empty_auth" result.should be_an_instance_of(Api::GetCountryListReply) result.status.should be_an_instance_of(Api::SoapStatus) result.status.code.should eql 0 result.status.errors.should be_an_instance_of Array result.status.errors.length.should eql 0 result.country_list.should be_an_instance_of Array result.country_list.first.should be_an_instance_of(Api::Country) result.country_list.should have(2).items end it_should_behave_like "All Web Services" it "should render a non-zero status for an invalid request" end The block of code that checks the status will appear in all of my specs for 50-60 APIs. My first thought was to move that to a method and that refactoring certainly makes things much drier as follows :- def status_should_be_valid(status) status.should be_an_instance_of(Api::SoapStatus) status.code.should eql 0 status.errors.should be_an_instance_of Array status.errors.length.should eql 0 end describe "Countries API" do it "should render a country list" do co1 = Factory(:country) co2 = Factory(:country) result = invoke :GetCountryList, "empty_auth" result.should be_an_instance_of(Api::GetCountryListReply) status_should_be_valid(result.status) result.country_list.should be_an_instance_of Array result.country_list.first.should be_an_instance_of(Api::Country) result.country_list.should have(2).items end end This works however I can not help feeling that this is not the "right" way to do it and I should be using shared specs, however looking at the method for defining shared specs I can not easily see how I would refactor this example to use a shared spec. How would I do this with shared specs and without having to re-run the relatively costly block at the beginning namely co1 = Factory(:country) co2 = Factory(:country) result = invoke :GetCountryList, "empty_auth"

• JQuery Autocomplete Form Submission

  - by user1658370

  I have managed to implement the jQuery autocomplete plugin on my website but was wondering if it is possible to make the form auto-submit once the user selects an item from the search. I have the following set-up: HTML Form: <form class="quick_search" action="../include/search.php" method="post"> <input type="text" name="search" id="search" value="Search..."> </form> JavaScript: $().ready(function() { $("#search").autocomplete("../include/search.php", { width: 350, selectFirst: false }); }); I have also included the jQuery and Autoplugin scripts. The search.php file contains a list of the search options. At the moment, the search works correctly and I just need it to submit the form once an item is selected from the list that appears. I tried to use the onClick and onSelect options within the search field but neither of these worked correctly. Any help would be much appreciated (I don't really understand js)! Thanks.

• jquery asp.net combo box question

  - by coson

  Good Day, I have a small form with a combo box (ASP.NET Drop Down List control) and a text box (with a DIV id txtName). When the selected index of the combo box changes, I want to clear out the text box. I understand that: $("#txtName").val(''); clears the text box value The thing is the combo box. It contains a list of integers representing the months of the year. The drop down control is called ddlMonths. $("#ddlMonths").change(function() { $("#txtName").val(''); }); I thought by using change, an onSelectedIndexChange event handler would be associated with this control. I also tried (because I've ran into the client id being mangled in ASP.NET w/ jQuery) this: $("#<%=ddlMonths.ClientID%>").change(function() { $("#<%=txtName.ClientID%>").val(''); }); and neither approach seems to be working. Am I missing something? TIA, coson

• Should the program logic reside inside the gui object class or be external to the class?

  - by hd112

  I have a question about how to structure code in relation to GUI objects. Suppose I have a dialog that has a list control that has a bunch of names obtained from a database. The user can edit the names. Does the logic reside inside that dialog class or should it be from the outside. To illustrate what I mean, here’s some pseudo code showing the structure of the code when the logic is handled outside the dialog class: NamesDialog : wxDialog { Private: ..stuff.. Public: ... SetNames(wxStringArray names); wxStringArray GetNames(); ..stuff.. } So the user of the class would do something like: wxStringArray names = DatabaseManager::Get()->GetNames(); names.Sort(); NamesDialogObject.SetNames(names); NamesDialogObject.ShowModal(); wxStringArray modified_names = NamesDialogObject.GetNames(); AddToDatabase(modified_names); //or something like this. On the other hand, the database logic can reside inside the NamesDialog class itself. In the show method I can query the database for the names and as the user interacts with the controls (list control in this case), the database can be updated from the event handlers. As a result the NamesDialog class only has the Show() method as there is no need to use SetNames or GetNames() etc. Which method is generally preferred? I don’t have much work experience so I’m not sure which is the proper way to handle it. Sometimes it's easier to handle everything in the class but getting access to objects it interacts with can be challenging. Generally can do it by having the relevant objects be singletons like the database manager in the above example.

• sql query selecting one name no matter how many rows it was mentioned in

  - by Baruch

  Basically what I'm trying to do is get the information from column x no matter how many times it was mentioned. means that if I have this kind of table: x | y | z ------+-------+-------- hello | one | bye hello | two | goodbye hi | three | see you so what I'm trying to do is create a query that would get all of the names that are mentions in the x column without duplicates and put it into a select list. my goal is that I would have a select list with TWO not THREE options, hello and hi this is what I have so far which isn't working. hope you guys know the answer to that: function getList(){ $options="<select id='names' style='margin-right:40px;'>"; $c_id = $_SESSION['id']; $sql="SELECT * FROM names"; $result=mysql_query($sql); $options.="<option value='blank'>-- Select something --</option>" ; while ($row=mysql_fetch_array($result)) { $name=$row["x"]; $options.="<option value='$name'>$name</option>"; } $options.= "</SELECT>"; return "$options"; } Sorry for confusing... i edited my source

• Using NHibernate's HQL to make a query with multiple inner joins

  - by Abu Dhabi

  The problem here consists of translating a statement written in LINQ to SQL syntax into the equivalent for NHibernate. The LINQ to SQL code looks like so: var whatevervar = from threads in context.THREADs join threadposts in context.THREADPOSTs on threads.thread_id equals threadposts.thread_id join posts1 in context.POSTs on threadposts.post_id equals posts1.post_id join users in context.USERs on posts1.user_id equals users.user_id orderby posts1.post_time where threads.thread_id == int.Parse(id) select new { threads.thread_topic, posts1.post_time, users.user_display_name, users.user_signature, users.user_avatar, posts1.post_body, posts1.post_topic }; It's essentially trying to grab a list of posts within a given forum thread. The best I've been able to come up with (with the help of the helpful users of this site) for NHibernate is: var whatevervar = session.CreateQuery("select t.Thread_topic, p.Post_time, " + "u.User_display_name, u.User_signature, " + "u.User_avatar, p.Post_body, p.Post_topic " + "from THREADPOST tp " + "inner join tp.Thread_ as t " + "inner join tp.Post_ as p " + "inner join p.User_ as u " + "where tp.Thread_ = :what") .SetParameter<THREAD>("what", threadid) .SetResultTransformer(Transformers.AliasToBean(typeof(MyDTO))) .List<MyDTO>(); But that doesn't parse well, complaining that the aliases for the joined tables are null references. MyDTO is a custom type for the output: public class MyDTO { public string thread_topic { get; set; } public DateTime post_time { get; set; } public string user_display_name { get; set; } public string user_signature { get; set; } public string user_avatar { get; set; } public string post_topic { get; set; } public string post_body { get; set; } } I'm out of ideas, and while doing this by direct SQL query is possible, I'd like to do it properly, without defeating the purpose of using an ORM. Thanks in advance! EDIT: The database looks like this: http://i41.tinypic.com/5agciu.jpg (Can't post images yet.)

• fastest public web app framework for quick DB apps?

  - by Steve Eisner

  I'd like to pick up a new tech for my toolbox - something for rapid prototyping of web apps. Brief requirements: public access (not hosted on my machine) - like Google's appengine, etc no tricky configuration necessary to build a simple web app host DB access (small storage provided) including some kind of SQLish query language easy front end HTML templating ability to access as a JSON service C# or Java,PHP or Python - or a fun new language to learn is OK free! An example app, very simple: render an AJAXy editable (add/delete/edit/drag) list of rich-data list items via some template language, so I can quickly mock up a UI for a client. ie. I can do most of the work client-side, but need convenient back end to handle the permanent storage. (In fact I suppose it doesn't even need HTML templating if I can directly access a DB via AJAX calls.) I realize this is a bit vague but am wondering if anyone has recommendations. A Rails host might be best for this (but probably not free) or maybe App Engine, or some other choice I'm not aware of? I've been doing everything with heavyweight servers (ASP.NET etc) for so long that I'm just not up on the latest... Thanks - I'll follow up on comments if this isn't clear enough :)

• Need help configuring Castle-Windsor

  - by Jonathas Costa

  I have these base interfaces and providers in one assembly (Assembly1): public interface IEntity { } public interface IDao { } public interface IReadDao<T> : IDao where T : IEntity { IEnumerable<T> GetAll(); } public class NHibernate<T> : IReadDao<T> where T : IEntity { public IEnumerable<T> GetAll() { return new List<T>(); } } And I have this implementation inside another assembly (Assembly2): public class Product : IEntity { public string Code { get; set; } } public interface IProductDao : IReadDao<Product> { IEnumerable<Product> GetByCode(string code); } public class ProductDao : NHibernate<Product>, IProductDao { public IEnumerable<Product> GetByCode(string code) { return new List<Product>(); } } I want to be able to get IRead<Product> and IProductDao from the container. I am using this registration: container.Register( AllTypes.FromAssemblyNamed("Assembly2") .BasedOn(typeof(IReadDao<>)).WithService.FromInterface(), AllTypes.FromAssemblyNamed("Assembly1") .BasedOn(typeof(IReadDao<>)).WithService.Base()); The IReadDao<Product> works great. The container gives me ProductDao. But if I try to get IProductDao, the container throws ComponentNotFoundException. How can I correctly configure the registration?

• Extract information from a Func<bool, T> or alike lambda

  - by Syska

  I''m trying to build a generic cache layer. ICacheRepository Say I have the following: public class Person { public int PersonId { get; set; } public string Firstname { get; set; } public string Lastname { get; set; } public DateTime Added { get; set; } } And I have something like this: list.Where(x => x.Firstname == "Syska"); Here I want to extract the above information, to see if the query supplied the "PersonId" which it did not, so I dont want to cache it. But lets say I run a query like this: list.Where(x => x.PersonId == 10); Since PersonId is my key ... I want to cache it. with the key like "Person_10" and I later can fetch it from the cache. I know its possible to extract the information with Expression<Func<>> but there seems to be a big overhead of doing this (when running compile and extract the Constant values etc. and a bunch of cache to be sure to parse right) Are there a framework for this? Or some smart/golden way of doing this ?

• Text replacement for multiple script/config files

  - by user343804

  I am doing some sort of science with a combination of Python, bash scripts and configuration files with weird syntaxes from old C programs. To run different tests, I have to tune (open text file, edit and save) a number of these files, but it is getting harder and harder to remember which files to edit. Also, the tasks are very repetitive and I end having a bunch of comment lines, switching on and off the settings for a specific run. I dream of a tool that can keep a list of files (regardless of the file format) and allow me to centrally choose from a predefined list of "profiles", taking care of editing the script/config files. For example lets say I have a config and script file: config.cfg var1 = 1.0 #var1 = 1.5 script.sct function(200.0) #function(300.0) I would like to instead have auxiliary text files: config.cfg.tem var1 = $$var1$$ script.sct.tem function($$par1$$) and in a central script or even better, a GUI, just switch from profile1 (e.g. var1=1.0,par1=200.0) to profile2 (e.g. var1=1.5,par1=300.0), and the tool to automatically update the text files. Any idea if such a tools exists?

• How would I sort files to directories based on filenames?

  - by gnomed

  I have a huge number of files to sort all named in some terrible convention. Here are some examples: (4)_mr__mcloughlin____.txt 12__sir_john_farr____.txt (b)mr__chope____.txt dame_elaine_kellett-bowman____.txt dr__blackburn______.txt These names are supposed to be a different person (speaker) each. Someone in another IT department produced these from a ton of XML files using some script but the naming is unfathomably stupid as you can see. I need to sort literally tens of thousands of these files with multiple files of text for each person; each with something stupid making the filename different, be it more underscores or some random number. They need to be sorted by speaker. This would be easier with a script to do most of the work then I could just go back and merge folders that should be under the same name or whatever. There are a number of ways I was thinking about doing this. parse the names from each file and sort them into folders for each unique name. get a list of all the unique names from the filenames, then look through this simplified list of unique names for similar ones and ask me whether they are the same, and once it has determined this it will sort them all accordingly. I plan on using Perl, but I can try a new language if it's worth it. I'm not sure how to go about reading in each filename in a directory one at a time into a string for parsing into an actual name. I'm not completely sure how to parse with regex in perl either, but that might be googleable. For the sorting, I was just gonna use the shell command: `cp filename.txt /example/destination/filename.txt` but just cause that's all I know so it's easiest. I dont even have a pseudocode idea of what im going to do either so if someone knows the best sequence of actions, im all ears. I guess I am looking for a lot of help, I am open to any suggestions. Many many many thanks to anyone who can help. B.

• Override one css class with another?

  - by user246114

  Hi, I have a list, with an li style defined. I want to replace the style of an individual element, but it doesn't seem to have any visual effect. Example: .myList li { background-color: yellow; } .foo { background-color: green; } <ul class='myList'> <li>Hello</li> </ul> When I add an item to the list, it has the .myList li style applied properly. I try now to remove all styles and apply the foo style to a single item (using jquery): $(item).removeClass(); $(item).addClass("foo"); the item does not change color to green though, but this reports the class is set to 'foo': alert($(item).attr('class')); so I guess I'm not understanding css rules here, looks like the li class definition is just overriding whatever else I do, however I want the reverse to be true, I want to override the li style definition with foo. How do we do this? Thanks

• LINQ Expression - Dynamic From & Where Clause

  - by chillydk147

  I have the following list of integers that I need to extract varying lists of integers containing numbers from say 2-4 numbers in count. The code below will extract lists with only 2 numbers. var numList = new List<int> { 5, 20, 1, 7, 19, 3, 15, 60, 3, 21, 57, 9 }; var selectedNums = (from n1 in numList from n2 in numList where (n1 > 10) && (n2 > 10) select new { n1, n2 }).ToList(); Is there any way to build up this Linq expression dynamically so that if I wanted lists of 3 numbers it would be compiled as below, this would save me having to package the similar expression inside a different method. var selectedNums = (from n1 in numList from n2 in numList from n3 in numList where (n1 > 10) && (n2 > 10) && (n3 > 10) select new { n1, n2, n3 }).ToList();

So there are two low_level values many mid_level values and a few top_level values but the trick is the top and mid level values are null and are assumed to be the values to the left. So, for instance all the columns above would have top_level1 as the top multi-index value. My best idea so far is to use transpose, but the it fills Unnamed: # everywhere and doesn't seem to work. In Pandas 0.13 read_csv seems to have a header parameter that can take a list, but this doesn't seem to work with parse.

• Inheritance concept java..help

  - by max

  Hi everyone. I'd be very grateful if someone could help me to understand the inheritance concept in Java. Is the following code an example of that? I mean the class WavPanel is actually a subclass of JPanel which acts as a superclass. Is that correct? If so it means that "what JPanel has, also WavPanel but it is more specific since through its methods you can do something else". Am I wrong? thank you. Max import javax.swing.JPanel; class WavPanel extends JPanel { List<Byte> audioBytes; List<Line2D.Double> lines; public WavPanel() { super(); setBackground(Color.black); resetWaveform(); } public void resetWaveform() { audioBytes = new ArrayList<Byte>(); lines = new ArrayList<Line2D.Double>(); repaint(); } }

  - by user1089173

  I have the following code List<Department> depts = new List<Department>(); Department.Add(new Department() { DNo = 1, DName = "Accounting", DFloor="6" }); Department.Add(new Department() { DNo = 2, DName = "FInance", DFloor="3" }); I want to bind this data to a GridView, so that it outputs the following. Observe the classes on each th and tr. How can I achieve this in ASP.NET? <thead> <tr> <th class="DNo">DNo</th> <th class="DName">DName</th> <th class= "DFloor">DFloor</th> </tr> </thead> <tr> <td class="DNo">1</td> <td class="DName">Accounting</td> <td class="DFloor">6</td> </tr> <tr> <td class="DNo">2</td> <td class="DName">FInance</td> <td class="DFloor">3</td> </tr>

• How to use vertical-align: middle; properly?

  - by Andrew

  I want to have my list (nav) align to the center of an image (logo). I tried using vertical-align: middle;, but I couldn't get it to work when I floated the images left and right. Here's my code: HTML: <div id="head"> <img id="logo" src="logo.png" /> <ul id="nav"> <li><a href="#">Item 1</a></li> <li><a href="#">Item 2</a></li> <li><a href="#">Item 3</a></li> </ul> </div> CSS: #head { margin-top: 2px; width: 100%; } #logo { float: left; } ul#nav { float: right; } ul#nav li { display: inline; list-style-type: none; } I took all the vertical-align: middle;'s from where I put them (I tested it in each element, even though it was only supposed to be applied to #logo, from what I've read.) Anyways, any help would be appreciated.

• Unable to access index for repository error?

  - by Tommy O'Dell

  I've just created a package (RTIO) and a package repository (Q:/Integrated Planning/R), which is a company network drive. I've put my package into the folder: Q:/Integrated Planning/R/bin/windows/contrib/2.15.1/RTIO_0.1-2.zip As per Dirk's instructions in this SO, I've run the following commands: > setwd("Q:/Integrated Planning/R/bin/windows/contrib/2.15.1") > tools::write_PACKAGES(".", type="win.binary") > list.files() [1] "PACKAGES" "PACKAGES.gz" "RTIO_0.1-2.zip" > With the code below, I've added the local repository to my list of repos (and I'll get other users to do the same): options(repos = c(getOption("repos"), RioTintoIronOre = "Q:/Integrated Planning/R")) And now trying to install my package I get an error: > install.packages("RTIO") Installing package(s) into ‘C:/Program Files/R/R-2.15.1/library’ (as ‘lib’ is unspecified) Warning in install.packages : unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15 Warning in install.packages : unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15 Warning in install.packages : unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15 Warning in install.packages : package ‘RTIO’ is not available (for R version 2.15.1) What does unable to access index for repository tell me? And how can I fix it? What I'm really looking to do is to do, under Windows and with RStudio as the IDE, is to let other internal R users add this package repo such that they're able to run commands like install.packages("RTIO") or update.packages() (and presumably use the IDE to manage packages via the GUI)?
