  • jquery :last missing multiple classes

    - by mickyjtwin
    I have an unordered list, and am using jquery to find the last ul and apply a class. jQuery("ul.class1:last").addClass("lastUi"); The html is as follows: <ul class="class1"></ul> <ul class="class1"></ul> This is working fine, however it has now changed in that another class is being added to the list so the html looks like: <ul class="class1"></ul> <ul class="class1 class2"></ul> <ul class="class1"></ul> <ul class="class1 class2"></ul> The jQuery code is now not picking up the last ul with both class1 and class2 as the last element and isn't adding the lastUI class.

  • Using reshape + cast to aggregate over multiple columns

    - by DamonJW
    In R, I have a data frame with columns for Seat (factor), Party (factor) and Votes (numeric). I want to create a summary data frame with columns for Seat, Winning party, and Vote share. For example, from the data frame df <- data.frame(party=rep(c('Lab','C','LD'),times=4), votes=c(1,12,2,11,3,10,4,9,5,8,6,15), seat=rep(c('A','B','C','D'),each=3)) I want to get the output seat winner voteshare 1 A C 0.8000000 2 B Lab 0.4583333 3 C C 0.5000000 4 D LD 0.5172414 I can figure out how to achieve this. But I'm sure there must be a better way, probably a cunning one-liner using Hadley Wickham's reshape package. Any suggestions? For what it's worth, my solution uses a function from my package djwutils_2.10.zip and is invoked as follows. But there are all sorts of special cases it doesn't deal with, so I'd rather rely on someone else's code. aggregateList(df, by=list(seat=seat), FUN=list(winner=function(x) x$party[which.max(x$votes)], voteshare=function(x) max(x$votes)/sum(x$votes)))

  • (SQL) Selecting from a database based on multiple pairs of pairs

    - by Owen Allen
    The problem i've encountered is attempting to select rows from a database where 2 columns in that row align to specific pairs of data. IE selecting rows from data where id = 1 AND type = 'news'. Obviously, if it was 1 simple pair it would be easy, but the issue is we are selecting rows based on 100s of pair of data. I feel as if there must be some way to do this query without looping through the pairs and querying each individually. I'm hoping some SQL stackers can provide guidance. Here's a full code break down: Lets imagine that I have the following dataset where history_id is the primary key. I simplified the structure a bit regarding the dates for ease of reading. table: history history_id id type user_id date 1 1 news 1 5/1 2 1 news 1 5/1 3 1 photo 1 5/2 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 If the user wants to select rows from the database based on a date range we would take a subset of that data. SELECT history_id, id, type, user_id, date FROM history WHERE date BETWEEN '5/3' AND '5/5' Which returns the following dataset history_id id type user_id date 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 Now, using that subset of data I need to determine how many of those entries represent the first entry in the database for each type,id pairing. IE is row 4 the first time in the database that id: 3, type: news appears. So I use a with() min() query. In real code the two lists are programmatically generated from the result sets of our previous query, here I spelled them out for ease of reading. WITH previous AS ( SELECT history_id, id, type FROM history WHERE id IN (1,2,3,4) AND type IN ('news','photo') ) SELECT min(history_id) as history_id, id, type FROM previous GROUP BY id, type Which returns the following data set. history_id id type user_id date 1 1 news 1 5/1 2 1 news 1 5/1 3 1 photo 1 5/2 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 You'll notice it's the entire original dataset, because we are matching id and type individually in lists, rather than as a collective pairs. The result I desire is, but I can't figure out the SQL to get this result. history_id id type user_id date 1 1 news 1 5/1 4 3 news 1 5/3 5 4 news 1 5/3 7 2 photo 1 5/4 Obviously, I could go the route of looping through each pair and querying the database to determine it's first result, but that seems an inefficient solution. I figured one of the SQL gurus on this site might be able to spread some wisdom. In case I'm approaching this situation incorrectly, the gist of the whole routine is that the database stores all creations and edits in the same table. I need to track each users behavior and determine how many entries in the history table are edits or creations over a specific date range. Therefore I select all type:id pairs from the date range based on a user_id, and then for each pairing I determine if the user is responsible for the first that occurs in the database. If first, then creation else edit. Any assistance would be awesome.

  • jQuery multiple class selection

    - by morpheous
    I am a bit confused with this: I have a page with a set of buttons (i.e. elements with class attribute 'button'. The buttons belong to one of two classes (grp1 and grp2). These are my requirements For buttons with class enabled, when the mouse hovers over them, a 'button-hover' class is added to them (i.e. the element the mouse is hovering over). Otherwise, the hover event is ignored When one of the buttons with class grp2 is clicked on (it has to be 'enabled' first), then I disable (i.e. remove the 'enabled' class for all elements with class 'enabled' (should probably selecting for elements with class 'button' AND 'enabled' - but I am having enough problems as it is, so I need to keep things simple for now). This is what my page looks like: <html> <head> <title>Demo</title> <style type="text/css" .button {border: 1px solid gray; color: gray} .enabled {border: 1px solid red; color: red} .button-hover {background-color: blue; } </style> <script type="text/javascript" src="jquery.js"></script> </head> <body> <div class="btn-cntnr"> <span class="grp1 button enabled">button 1</span> <span class="grp2 button enabled">button 2</span> <span class="grp2 button enabled">button 3</span> <span class="grp2 button enabled">button 4</span> </div> <script type="text/javascript"> /* <![CDATA[ */ $(document).ready(function(){ $(".button.enabled").hover(function(){ $(this).toggleClass('button-hover'); }, function() { $(this).toggleClass('button-hover'); }); $('.grp2.enabled').click(function(){ $(".grp2").removeClass('enabled');} }); /* ]]> */ </script> </body> </html> Currently, when a button with class 'grp2' is clicked on, the other elements with class 'grp2' have the 'enabled' class removed (works correctly). HOWEVER, I notice that even though the class no longer have a 'enabled' class, SOMEHOW, the hover behaviour is still applied to these elemets (WRONG). Once an element has been 'disabled', I no longer want it to respond to the hover() event. How may I implement this behavior, and what is wrong with the code above (i.e. why is it not working? (I am still learning jQuery)

    I'm building an e-commerce website in ASP.Net/C# and I'm having some difficulties with my shopping cart... I want my costumers to be able to say "I want X boxes, and each box carries Y items". Let's say, for instance, my website sells flowers. A client logs in and then chooses X bouquets and then for each bouquet he adds flowers from the catalog. Can you point me out some links or tips in order to achieve this behaviour? Thanks

  • CREATE VIEW called multiple times not creating all views

    - by theninepoundhammer
    Noticing strange behavior in SQL 2005, both Express and Enterprise Edition: In my code I need to loop through a series of values (about five in a row), and for each value, I need to insert the value into a table and dynamically create a new view using that value as part of the where clause and the name of the view. The code runs pretty quickly, but what I'm noticing is that all the values are inserted into the table correctly but only the LAST view is being created. Every time. For example, if the values I'm using are X1, X2, X3, X4, and X5, I'll run the process, open up Mgmt Studio, and see five rows in the table with the correct five values, but only one view named MyView_x5 that has the correct WHERE clause. At first, I had this loop in an SSIS package as part of a larger data flow. When I started noticing this behavior, I created a stored proc that would create the CREATE VIEW statement dynamically after the insert and called EXECUTE to create the view. Same result. Finally, I created some C# code using the Enterprise Library DAAB, and did the insert and CREATE VIEW statements from my DLL. Same result every time. Most recently, I turned on Profiler while running against the Enterprise Edition and was able to verify that the Batch Started and Batch Completed events were being fired off for each instance of the view. However, like I said, only the last view is actually being created. Does anyone have any idea why this might be happening? Or any suggestions about what else to check or profile? I've profiled for error messages, exceptions, etc. but don't see any in my trace file. My express edition is 9.00.1399.06. Not sure about the Enterprise edition but think it is SP2.

  • Extracting RAR archive into multiple directories on Windows

    - by user368565
    Hello, On a Windows box, I need to extract a RAR archive so that individual files in it go into specific directories. I can provide, say, a text file that lists each file and the target directory for it. Then I need help creating a batch file that will actually extract these files into their target locations. Please help. E.g. RAR archive x.rar contains a.a b.b c.c Text file x.txt says a.a C:\foo b.b C:\bar c.c C:\foo Result of running batch file on x.rar and x.txt should be: in C:\foo we have a.a and c.c in C:\bar we have b.b Thanks!

  • Trouble with Action<T1, T2> and passing multiple parameters

    - by dotnetdev
    Hi, I have this code: s(x => x.Open()); s is a method which calls one parameter, which is perfectly fine, like so: public void s(Action<p1> action) {} Ignoring the naming conventions, if I make the method like the below: public void s(Action<p1, p2> action) {} How do I pass in more than one parameter? Out of interest, is there any way to use the params keyword with Action<? Also, I am using C# 4.0 so I would be interested to see how it can help me in an way. Thanks

  • R- delete rows in multiple columns by unique number

    - by Vincent Moriarty
    Given data like this C1<-c(3,-999.000,4,4,5) C2<-c(3,7,3,4,5) C3<-c(5,4,3,6,-999.000) DF<-data.frame(ID=c("A","B","C","D","E"),C1=C1,C2=C2,C3=C3) How do I go about removing the -999.000 data in all of the columns I know this works per column DF2<-DF[!(DF$C1==-999.000 | DF$C2==-999.000 | DF$C3==-999.000),] But I'd like to avoid referencing each column. I am thinking there is an easy way to reference all of the columns in a particular data frame aka: DF3<-DF[!(DF[,]==-999.000),] or DF3<-DF[!(DF[,(2:4)]==-999.000),] but obviously these do not work And out of curiosity, bonus points if you can me why I need that last comma before the ending square bracket as in: ==-999.000),]

  • Amazon EC2 multiple servers share session state

  • What is faster: multiple `send`s or using buffering?

    - by dauerbaustelle
    I'm playing around with sockets in C/Python and I wonder what is the most efficient way to send headers from a Python dictionary to the client socket. My ideas: use a send call for every header. Pros: No memory allocation needed. Cons: many send calls -- probably error prone; error management should be rather complicated use a buffer. Pros: one send call, error checking a lot easier. Cons: Need a buffer :-) malloc/realloc should be rather slow and using a (too) big buffer to avoid realloc calls wastes memory. Any tips for me? Thanks :-)

  • Multiple Solution Layout for ASP.NET Web Portal?

    - by Jared S
    At work, we've developed a custom ASP.NET Web Portal (That's very similar to iGoogle). We have "Apps" (self-contained, large web forms) and "Modules" (similar to Google Gadgets). Currently, we use a single-solution model. Right now, we have: 3 core projects 60 application projects 80 module projects To reduce copy and pasting between projects, we're going to factor out common functionality (Data Access, Business Logic) into separate projects. I'd also like to introduce Unit Tests, which is going to increase the number of projects even more. We've already reached the point where Visual Studio is choking on the number of projects. We generally only load the 3 core projects and then whatever app's/module's project we're working on. Would a different solution structure help us out? Our number of projects is only going to increase. In general, an app or module only references the 3 core projects. Soon, apps/modules may start referencing the Data Access/Business Logic projects. But in general, apps and modules do not make references between themselves. So to recap, what is the best practice for solution structure when there are MANY projects that use a small number of core projects?

  • Use multiple css files or a single file organised by comments

    - by David
    Hi, what is regarded as the best approach to organising css. At the moment I am using a single link in the head of my xhtml documents as follows: <link rel="stylesheet" type="text/css" href="style/imports.css" /> In this file im importing several different css files i.e. reset.css, structure.css, skin.css I know there is an overhead in doing this as each requires an extra trip to the server but it makes things much more logical and organised in my opinion. Does anyone have an opinion on how best to organise their css. - Would it be better to put all these seperate css funcions into one single file? Also, is it best practice to minify css.

  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

  • plotting multiple google maps to page

    - by Roland
    I'm trying to append more than one Google Map to a page. But it seems like I'm having some trouble. This would be the template I'm using to ( with Handlebars.js ) to create the same block more than once, about 50 times : <script type="text/x-handlebars-template"> {{#each productListing}} <div class="product-listing-wrapper"> <div class="product-listing"> <div class="left-side-content"> <div class="thumb-wrapper" data-image-link="{{ThumbnailUrl}}"> <i class="thumb"> <img src="{{ThumbnailUrl}}" alt="Thumb"> <span class="zoom-image"></span> </i> </div> <div class="google-maps-wrapper"> <div class="google-coordonates-wrapper"> <div class="google-coordonates"> <p>{{LatLon.Lat}}</p> <p>{{LatLon.Lon}}</p> </div> </div> <div class="google-maps-button"> <a class="google-maps" href="#">Google Maps</a> </div> </div> </div> <div class="right-side-content"> <div class="map-canvas-wrapper"> <div id="map-canvas" class="map-canvas" data-latitude="{{LatLon.Lat}}" data-longitude="{{LatLon.Lon}}"></div> </div> <div class="content-wrapper"></div> </div> </div> </div> {{/each}} And I'm trying to append the map to the #map-canvas id. With the following block of code I'm doing the plotting : Cluster.prototype.initiate_map_assembling = function() { return $(this.map_canvas_wrapper_class).each(function(index, element) { var canvas = $(element).children(); var latitude = $(canvas).attr('data-latitude'); var longitude = $(canvas).attr('data-longitude'); var coordinates = new google.maps.LatLng(latitude, longitude); var options = { zoom: 9, center: coordinates, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map($(canvas), options); var marker = new google.maps.Marker({ position: coordinates, map: map }); }); }; This way I'm "looping" through all the parent classes of the id I'm trying to append the map to, but the map would only append to the first id. I tried to append it to all of the id's in other ways but with the same results. So what would you suggest me to do to make it work as I would expect it, append the map to each of the id's ?

  • How to specify multiple values in where with AR query interface in rails3

    - by wkhatch
    Per section 2.2 of rails guide on Active Record query interface here: which seems to indicate that I can pass a string specifying the condition(s), then an array of values that should be substituted at some point while the arel is being built. So I've got a statement that generates my conditions string, which can be a varying number of attributes chained together with either AND or OR between them, and I pass in an array as the second arg to the where method, and I get: ActiveRecord::PreparedStatementInvalid: wrong number of bind variables (1 for 5) which leads me to believe I'm doing this incorrectly. However, I'm not finding anything on how to do it correctly. To restate the problem another way, I need to pass in a string to the where method such as "table.attribute = ? AND table.attribute1 = ? OR table.attribute1 = ?" with an unknown number of these conditions anded or ored together, and then pass something, what I thought would be an array as the second argument that would be used to substitute the values in the first argument conditions string. Is this the correct approach, or, I'm just missing some other huge concept somewhere and I'm coming at this all wrong? I'd think that somehow, this has to be possible, short of just generating a raw sql string.
