  • Count words like Microsoft Word does

    - by Maarten
    I need to count words in a string using PHP or Javascript (preferably PHP). The problem is that the counting needs to be the same as it works in Microsoft Word, because that is where the people assemble their original texts in so that is their reference frame. PHP has a word counting function (http://php.net/manual/en/function.str-word-count.php) but that is not 100% the same as far as I know. Any pointers?

  • warning: returning reference to temporary

    - by Jack
    I have a function like this const string &SomeClass::Foo(int Value) { if (Value < 0 or Value > 10) return ""; else return SomeClass::StaticMember[i]; } I get warning: returning reference to temporary. Why is that? I thought the both values the function returns (reference to const char* "" and reference to a static member) cannot be temporary.

  • overriding previously-bound click events

    - by JamesBrownIsDead
    When I use this code with an element whose id is "foobar": $("#foobar").click(function () { alert("first"); }); $("#foobar").click(function () { alert("second"); }); I get two alerts: "first" and "second" second. How do I specify a click event that also clears out any previous click events attached to the element? I want the last $("#foobar").click(...) to erase any previously bound events.

  • Bind multiple events to jQuery 'live' method

    - by Will Peavy
    jQuery's 'live' method is unable to handle multiple events. Does anyone know of a good workaround to attach multiple events to a function that polls current and future elements? Or am I stuck using duplicate live methods for each event handler I need? Example - I am trying to do something like: $('.myclass').live('change keypress blur', function(){ // do stuff });

  • DocumentFragment not appending in IE

    - by bmwbzz
    I have a select list which, when changed, pulls data via ajax and dynamically creates select lists. Then based on the data used to create the select lists (a type), I pull more data via ajax if i don't have it already and create the options for the select list and store them in a fragment. Then I append that fragment to the select list. This is zippy in FF3 and Chrome but either doesn't append the options at all or takes a long time (minutes) to append the options in IE7. Note: I am also using jQuery. code from the success callback which creates the select lists: blockDiv.empty(); var contentItemTypes = new Array(); selectLists = new Array(); for (var post in msg) { if (post != undefined) { var div = fragment.cloneNode(true); //deep copy var nameDiv = $(div.firstChild); nameDiv.text(msg[post].Name); blockDiv[0].appendChild(div); var allSelectLists = blockDiv.find('.editor-field select'); var selectList = $(allSelectLists[allSelectLists.length - 1]); var blockId = msg[post].ID; var elId = 'PageContentItem.' + blockId; selectList.attr('id', elId); selectList.attr('name', elId); var contentItemTypeId = msg[post].ContentItemTypeId; selectList.attr('cit', contentItemTypeId); if (contentItems[contentItemTypeId] != null || contentItems[contentItemTypeId] != undefined) { contentItems[contentItemTypeId] = null; } selectLists[post] = selectList; } } var firstContentTypeId = selectLists[0].attr('cit'); getContentItems(firstContentTypeId, setContentItemsForList, 0); code to get the items for the options in the select lists. function getContentItems(contentTypeId, callback, callbackParam) { if (contentItems[contentTypeId] != null || contentItems[contentTypeId] != undefined) { callback(contentTypeId, callbackParam); return; } contentItems[contentTypeId] = document.createDocumentFragment(); Q.ajax({ type: "POST", url: "/CMS/ContentItem/ListByContentType/" + contentTypeId, data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", error: function(xhr, msg, e) { var err = eval("(" + xhr.responseText + ")"); alert(err.ExceptionType + " ***** " + err.Message + " ***** " + err.StackTrace); }, success: function(msg) { var li; for (var post in msg) { if (post != undefined) { li = $('<option value="' + msg[post].ID + '">' + msg[post].Description + '</option>'); contentItems[contentTypeId].appendChild(li[0]); } } callback(contentTypeId, callbackParam); } }); } function setContentItemsForList(contentTypeId, selectIndex) { if (selectIndex < selectLists.length) { var items = contentItems[contentTypeId].cloneNode(true); selectLists[selectIndex].append($(items.childNodes)); selectIndex++; if (selectIndex < selectLists.length) { var nextContentTypeId = selectLists[selectIndex].attr('cit'); getContentItems(nextContentTypeId, setContentItemsForList, selectIndex); } } }

  • Working with arrays passed byref

    - by Jason
    I would like for someone to explain this to me: function myFunction(array){ array = $.grep(array, function(n,i){return n > 1 }); } var mainArray = [1,2,3]; myFunction(mainArray); document.write(mainArray) // 1,2,3, but i'm expecting 2,3 but if i do something like array[3] = 4; in place of the $.grep line, i get 1,2,3,4. Shouldn't mainArray become the new array created by $.grep?

  • Why is this code's execution speed so different?

    - by Steve Watkins
    In Internet Explorer 7, this code executes consistently in 47 ms: function updateObjectValues() { $('.objects').html(12345678); // ~500 DIVs } however, this code executes consistently in 157 ms: function updateObjectValues() { $('.objects').html('12345678'); // ~500 DIVs } Passing a number is over 3x faster than a string. Why are these results so dramatically different? And, is there any way to help the performance of the string?

  • How to apply or chain multiple matching templates in XSLT?

    - by Ignatius
    I am working on a stylesheet employing many templates with match attributes: <xsl:template match="//one" priority="0.7"> <xsl:param name="input" select="."/> <xsl:value-of select="util:uppercase($input)"/> <xsl:next-match /> </xsl:template> <xsl:template match="/stuff/one"> <xsl:param name="input" select="."/> <xsl:value-of select="util:add-period($input)"/> </xsl:template> <xsl:function name="util:uppercase"> <xsl:param name="input"/> <xsl:value-of select="upper-case($input)"/> </xsl:function> <xsl:function name="util:add-period"> <xsl:param name="input"/> <xsl:value-of select="concat($input,'.')"/> </xsl:function> What I would like to do is be able to 'chain' the two functions above, so that an input of 'string' would be rendered in the output as 'STRING.' (with the period.) I would like to do this in such a way that doesn't require knowledge of other templates in any other template. So, for instance, I would like to be able to add a "util:add-colon" method without having to open up the hood and monkey with the existing templates. I was playing around with the <xsl:next-match/> instruction to accomplish this. Adding it to the first template above does of course invoke both util:uppercase and util:add-period, but the output is an aggregation of each template output (i.e. 'STRINGstring.') It seems like there should be an elegant way to chain any number of templates together using something like <xsl:next-match/>, but have the output of each template feed the input of the next one in the chain. Am I overlooking something obvious?

  • Performance of looping over an Unboxed array in Haskell

    - by Joey Adams
    First of all, it's great. However, I came across a situation where my benchmarks turned up weird results. I am new to Haskell, and this is first time I've gotten my hands dirty with mutable arrays and Monads. The code below is based on this example. I wrote a generic monadic for function that takes numbers and a step function rather than a range (like forM_ does). I compared using my generic for function (Loop A) against embedding an equivalent recursive function (Loop B). Having Loop A is noticeably faster than having Loop B. Weirder, having both Loop A and B together is faster than having Loop B by itself (but slightly slower than Loop A by itself). Some possible explanations I can think of for the discrepancies. Note that these are just guesses: Something I haven't learned yet about how Haskell extracts results from monadic functions. Loop B faults the array in a less cache efficient manner than Loop A. Why? I made a dumb mistake; Loop A and Loop B are actually different. Note that in all 3 cases of having either or both Loop A and Loop B, the program produces the same output. Here is the code. I tested it with ghc -O2 for.hs using GHC version 6.10.4 . import Control.Monad import Control.Monad.ST import Data.Array.IArray import Data.Array.MArray import Data.Array.ST import Data.Array.Unboxed for :: (Num a, Ord a, Monad m) => a -> a -> (a -> a) -> (a -> m b) -> m () for start end step f = loop start where loop i | i <= end = do f i loop (step i) | otherwise = return () primesToNA :: Int -> UArray Int Bool primesToNA n = runSTUArray $ do a <- newArray (2,n) True :: ST s (STUArray s Int Bool) let sr = floor . (sqrt::Double->Double) . fromIntegral $ n+1 -- Loop A for 4 n (+ 2) $ \j -> writeArray a j False -- Loop B let f i | i <= n = do writeArray a i False f (i+2) | otherwise = return () in f 4 forM_ [3,5..sr] $ \i -> do si <- readArray a i when si $ forM_ [i*i,i*i+i+i..n] $ \j -> writeArray a j False return a primesTo :: Int -> [Int] primesTo n = [i | (i,p) <- assocs . primesToNA $ n, p] main = print $ primesTo 30000000

  • Raphaeljs animation kills my browser

    - by user1688606
    I have this code where I have a made a character using 20 paths and put it into a set. Now when I animate the set, the first transformation runs smoothly, the second animation stutters, the third animation doesn't happen as it should and the 4th animation kills my pc, the browser hangs and in the task manager I can see that it consumes up to 70% of CPU. How can I avoid this and free the resources so all the animations run smoothly. *I have to execute 10 simple y-axis transformation animations on that character. JS Fiddle window.onload = function(){ var paper = Raphael(0,0,400,400); var character = paper.set(); paper.setStart(); var attr = {fill:'red',stroke:'none'}; var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var character = paper.setFinish(); character.transform("t0,200") //1st animation.. var chartrnsfrm = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm1.delay(2000)) }); character.animate(chartrnsfrm.delay(2000)); //2nd animation.. var chartrnsfrm1 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm2.delay(2000)) }); //3rd animation.. var chartrnsfrm2 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm3.delay(2000)) }); //4th animation.. var chartrnsfrm3 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout"); }

  • Should I use fork or threads?

    In my script, I have a function foo which basically uses pynotify to notify user about something repeatedly after a time interval say 15 minutes. def foo: while True: """Does something""" time.sleep(900) My main script has to interact with user & does all other things so I just cant call the foo() function. directly. Whats the better way of doing it and why? Using fork or threads?

  • jquery delegate table rows selector

    - by Jackob
    I have a table which may contains other inner tables (it's not possible to edit generated markup). I want to create a delegate function for row mouseenter and mouseleave which only triggers for the associated main table rows (and not inner tables rows), as following: $("#tableid").delegate("tr", "mouseenter mouseleave", function(e) { //do stuff here }); But with this selector it selects also the inner table rows, so how can I modify the selector to avoid selecting inner table rows?

  • JavaFX - question regarding binding button's disabled state

    - by jamiebarrow
    I'm trying to create a dummy application that maintains a list of tasks. For now, all I'm trying to do is add to the list. I enter a task name in a text box, click on the add task button, and expect the list to be updated with the new item and the task name input to be cleared. I only want to be able to add tasks if the task name is not empty. The below code is my implementation, but I have a question regarding the binding. I'm binding the textbox's text variable to a string in my view model, and the button's disable variable to a boolean in my view model. I have a trigger to update the disabled state when the task name changes. When the binding of the task name happens the boolean is updated accordingly, but the button still appears disabled. But then when I mouse over the button, it becomes enabled. I believe this is due to JavaFX 1.3's binding being lazy - only updates the bound variable when it is read. Also, when I've added the task, I clear the task name in the model, but the textbox's text doesn't change - even though I'm using bind with inverse. Is there a way to make the textbox's text and the button's disabled state update automatically via the binding as I was expecting? Thanks, James AddTaskViewModel.fx: package jamiebarrow; import java.lang.System; public class AddTaskViewModel { function logChange(prop:String,oldValue,newValue):Void { println("{System.currentTimeMillis()} : {prop} [{oldValue}] to [{newValue}] "); } public var newTaskName: String on replace old { logChange("newTaskName",old,newTaskName); isAddTaskDisabled = (newTaskName == null or newTaskName.trim().length() == 0); }; public var isAddTaskDisabled: Boolean on replace old { logChange("isAddTaskDisabled",old,isAddTaskDisabled); }; public var taskItems = [] on replace old { logChange("taskItems",old,taskItems); }; public function addTask() { insert newTaskName into taskItems; newTaskName = ""; } } Main.fx: package jamiebarrow; import javafx.scene.control.Button; import javafx.scene.control.TextBox; import javafx.scene.control.ListView; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.stage.Stage; import javafx.scene.layout.HBox; def viewModel = AddTaskViewModel{}; var txtName: TextBox = TextBox { text: bind viewModel.newTaskName with inverse onKeyTyped: onKeyTyped }; function onKeyTyped(event): Void { txtName.commit(); // ensures model is updated cmdAddTask.disable = viewModel.isAddTaskDisabled;// the binding only occurs lazily, so this is needed } var cmdAddTask = Button { text: "Add" disable: bind viewModel.isAddTaskDisabled with inverse action: onAddTask }; function onAddTask(): Void { viewModel.addTask(); } var lstTasks = ListView { items: bind viewModel.taskItems with inverse }; Stage { scene: Scene { content: [ VBox { content: [ HBox { content: [ txtName, cmdAddTask ] }, lstTasks ] } ] } }
