  • Javascript push Object to cookies using JSON

    - by Hunkeone
    Hi All on click button I need to add object to array and then write array to cookies. From the start this array can be not empty so I parse cookie first. function addToBasket(){ var basket = $.parseJSON($.cookie("basket")) if (basket.length==0||!basket){ var basket=[]; basket.push( { 'number' : this.getAttribute('number'), 'type' : this.getAttribute('product') } ); } else{ basket.push( { 'number' : this.getAttribute('number'), 'type' : this.getAttribute('product') } ); } $.cookie("basket", JSON.stringify(basket)); } And HTML <button type="button" class="btn btn-success btn-lg" number="12" product="accs" onclick="addToBasket()">Add</button> Unfortunately I'm getting Uncaught ReferenceError: addToBasket is not defined onclick. Can't understand what am I doing wrong? Thanks!

  • How to paste text and variables into a logical expression in R?

    - by Jasper
    I want to paste variables in the logical expression that I am using to subset data, but the subset function does not see them as column names when pasted (either with ot without quotes). I have a dataframe with columns named col1, col2 etc. I want to subset for the rows in which colx < 0.05 This DOES work: subsetdata<-subset(dataframe, col1<0.05) subsetdata<-subset(dataframe, col2<0.05) This does NOT work: for (k in 1:2){ subsetdata<-subset(dataframe, paste("col",k,sep="")<0.05) } for (k in 1:2){ subsetdata<-subset(dataframe, noquote(paste("col",k,sep=""))<0.05) } I can't find the answer; any suggestions?

  • When using DrawText, what does TextFormatFlags.Internal (a.k.a. DT_INTERNAL) do?

    - by Daniel Stutzbach
    When using TextRenderer.DrawText(), what does setting the TextFormatFlags.Internal flag actually do? Equivalently, what does setting the DT_INTERNAL flag to Win32's DrawTextEx() function do? More to the point, when should I set that flag and when should I not set it? The documentation says: "Uses the system font to calculate text metrics", but I'm not entirely sure what that means. I've done some limited testing and setting the flag seems to change how the font is rendered when using a small font size, but doesn't seem to make a difference when using a large font size.

  • Handling Timeouts In A Website SQLCommand Object and c#

    - by user341684
    I'm using visual studio 2008 and sql server 2005 and everything is working just fine under normal use. However if a user is on a page for a while several minutes with no activity then clicks a button on occassion the site throws the following exception ... Procedure or Function "sp_name" parameter '@SomeParameterName', which was not supplied I'm also encountering this error in Visual Studio while debugging the application, in otherwords run the site from visual studio then make some change to the html in VS save the changes and refresh the page. The error is not consistent nor is the time the page has to stay idle in order for it to occur.... The current sql command object timeout is 30 secs and the website timeout is 30 minutes. Has anyone else experienced this scenario and what is the fix as I would not except anything to go out of scope until the website timeout occurs ... Any insight will be appreciated.

  • How to stream an HttpResponse with Django

    - by muudscope
    I'm trying to get the 'hello world' of streaming responses working for Django (1.2). I figured out how to use a generator and the yield function. But the response still not streaming. I suspect there's a middleware that's mucking with it -- maybe ETAG calculator? But I'm not sure how to disable it. Can somebody please help? Here's the "hello world" of streaming that I have so far: def stream_response(request): resp = HttpResponse( stream_response_generator()) return resp def stream_response_generator(): for x in range(1,11): yield "%s\n" % x # Returns a chunk of the response to the browser time.sleep(1)

  • Understanding Clojure concurrency example

    - by dusha
    Hello, I just go through various documentation on Clojure concurrency and came accross the example on the website (http://clojure.org/concurrent_programming). (import '(java.util.concurrent Executors)) (defn test-stm [nitems nthreads niters] (let [refs (map ref (replicate nitems 0)) pool (Executors/newFixedThreadPool nthreads) tasks (map (fn [t] (fn [] (dotimes [n niters] (dosync (doseq [r refs] (alter r + 1 t)))))) (range nthreads))] (doseq [future (.invokeAll pool tasks)] (.get future)) (.shutdown pool) (map deref refs))) I understand what it does and how it works, but I don't get why the second anonymous function fn[] is needed? Many thanks, dusha. P.S. Without this second fn [] I get NullPointerException.

  • ShGetFileInfo called for directory oddity

    - by Axarydax
    Hello, I have a simple file browser and there I display files and folders, obtained by (for directory) SHFILEINFO info = new SHFILEINFO(); SHGetFileInfo(filename, FILE_ATTRIBUTE_DIRECTORY, ref info,Marshal.SizeOf(info), SHGFI_ICON | SHGFI_USEFILEATTRIBUTES | SHGFI_SMALLICON | SHGFI_ADDOVERLAYS); It works 100% fine, but I have noticed an oddity - if I try to obtain an icon for directory, but specify FILE_ATTRIBUTE_NORMAL instead of FILE_ATTRIBUTE_DIRECTORY but it does weird stuff for directories - normal folders have "unknown file type white paper" icons, recycle bin has VLC icon, etc. Directories under SVN have proper overlay, but base file icon (white sheet of paper). I understand that base icon for directory would now be the one of unknown file, but why do some folders have totally strange icon? Config.MSI has installer icon, recycle bin has VLC icon (wtf?!), etc. What does the shell function do with this parameters? Exactly what icon does it obtain? Again, this is not a problem, I'm just curious.

  • Getting users latest tweet with Django

    - by Hanpan
    I want to create a function which grabs every users latest tweet from a specific group. So, if a user is in the 'authors' group, I want to grab their latest tweet and then finally cache the result for the day so we only do the crazy leg work once. def latest_tweets(self): g = Group.objects.get(name='author') users = [] for u in g.user_set.all(): acc = u.get_profile().twitter_account users.append('http://twitter.com/statuses/user_timeline/'+acc+'.rss') return users Is where I am at so far, but I'm at a complete loose end as to how I parse the RSS to get there latest tweet. Can anyone help me out here? If there is a better way to do this, any suggestions are welcome! I'm sure someone will suggest using django-twitter or other such libraries, but I'd like to do this manually if possible. Cheers

  • store data in asp.net pages (Not Sessions)

    - by ARB
    I am creating 4 asp.net pages. first three pages have 'CONTINUE' button and last page has 'SUBMIT' button. I am not allowed to use Sessions to store first three pages data. and i need to use 'BACK' button on last three pages. when i click 'BACK' button i need to maintain the previous page data entered by user. As my pages do some postbacks, i cannot use javascript.history function. My restrictions are: As the application is served from a web farm, a session object cannot be used. However, for the purpose of this excersise, consider session object as database-like persistent space where you can store your data. your code should show an easy way to switch to a different persistent space. What is databse like persistent space and how to write a code to switch to different persistent space?... Please give me some idea on how to proceed.... Thank you

  • My image does not load on a jQuery fade in effect even though the div loads.

    - by Konstantin
    jQuery(document).ready(function() { if (useMSIE){ pngfixALL(); }; jQuery(div).show(data_fadeInEffect, 500);return false; // jQuery(div).animate({opacity:1}, 500, 'linear'); }); This is what I have for a fade in effect. When using animate(), the image in the div tag fades in fine. However, when I use show(), the div loads because I can click in that area, but the image itself doesn't load. Why is this happening? I have another area of the code where I click on an 'x' in the image and it fades out using hide(). This works fine.

    I am making a simple online application. I have a navigation bar with a few buttons and one "div" into which all the new contents will be loaded dynamically i.e. when I click "About", it will load the page parts into the "div" without reloading the whole page with .load() function. The problem is: what if I need to give a link to the Documents section of my web site, or the user wants to store this kind of link, the url is not rewritten when browsing my site. when the user stores the default link it will always link him to the default "Home" part. How can I rewrite the URL and what is the most correct way to do this?

  • hadoop mapper static initialisation

    Hi, I have a code fragment in which I am using a static code block to initialize a variable. public static class JoinMap extends Mapper<IntWritable, MbrWritable, LongWritable, IntWritable> { ....... public static RTree rt = null; static { String rtreeFileName = "R.rtree"; rt = new RTree(rtreeFileName); } public void map(IntWritable key, MbrWritable mbr,Context context) throws IOException, InterruptedException { ......... List elements = rt.overlaps(mbr.getRect()); ....... } } My problem is that the variable rt in the above code fragment is not getting initialised. Can anybody suggest a fix or an alternate way to initialise the variable. I don't want to initialise it inside my map function since that slows down the entire process.

  • How can one describe a rock-paper-scissors relationship between 3 items?

    - by Madara Uchiha
    Let's say I have the following structure: abstract class Hand {} class Rock extends Hand {} class Paper extends Hand {} class Scissors extends Hand {} The goal is to make a function (or a method) Hand::compareHands(Hand $hand1, Hand $hand2), which would return the winning hand in a rock-paper-scissors match. That would be very easy with a bunch of ifs, but the point is to have a more robust structure, that's relying on polymorphism rather than on procedural code. P.S. this is done in actual production code, if someone is asking. This isn't some sort of challenge or homework. (It's not really rock-paper-scissors, but you get the point).

  • sqlite3 date operations when joining two tables in a view?

    - by duncan
    In short, how to add minutes to a datetime from an integer located in another table, in one select statement, by joining them? I have a table P(int id, ..., int minutes) and a table S(int id, int p_id, datetime start) I want to generate a view that gives me PS(S.id, P.id, S.start + P.minutes) by joining S.p_id=P.id The problem is, if I was generating the query from the application, I can do stuff like: select datetime('2010-04-21 14:00', '+20 minutes'); 2010-04-21 14:20:00 By creating the string '+20 minutes' in the application and then passing it to sqlite. However I can't find a way to create this string in the select itself: select p.*,datetime(s.start_at, formatstring('+%s minutes', p.minutes)) from p,s where s.p_id=p.id; Because sqlite as far the documentation tells, does not provide any string format function, nor can I see any alternative way of expressing the date modifiers.

  • Accessing subclass members from a superclass pointer C++

    - by Dr. Monkey
    I have an array of custom class Student objects. CourseStudent and ResearchStudent both inherit from Student, and all the instances of Student are one or the other of these. I have a function to go through the array, determine the subtype of each Student, then call subtype-specific member functions on them. The problem is, because these functions are not overloaded, they are not found in Student, so the compiler kicks up a fuss. If I have a pointer to Student, is there a way to get a pointer to the subtype of that Student? Would I need to make some sort of fake cast here to get around the compile-time error?
