  • Extracting numbers from a url using javascript?

    - by stormist
    var exampleURL = '/example/url/345234/test/'; var numbersOnly = [?] The /url/ and /test portions of the path will always be the same. Note that I need the numbers between /url/ and /test. In the example URL above, the placeholder word example might be numbers too from time to time but in that case it shouldn't be matched. Only the numbers between /url/ and /test. Thanks!

  • JS Split ( ) to check if substring exists in Array

    - by Javacadabra
    I have an array of products that are stored as Strings in this format productname:quantity. The issue I am running into is that if a user adds one product with a quantity of x it is inserted into the array as it should. However, if they then decide to add more of a particular product a new entry is made into the array instead of checking if the product already exists and adjusting the quantity to the new value. oldQty + newQty. For example this is my array: ["CBL202659/A:1","OUTER9:1","PALLET CARDS:1"] If I add another PALLET CARDS product it creates a new entry rather than updating the quantity of the existing item to 2. New array ["CBL202659/A:1","OUTER9:1","PALLET CARDS:1","PALLET CARDS:1"] I would like the array to end up like this: - updating the quantity ["CBL202659/A:1","OUTER9:1","PALLET CARDS:2"] Currently this is my code: I use the split() method to seperate the String where a colon occurs and store the product name and quantity in two seperate variables. $(".orderBtn").click(function(event){ //Show the order Box $(".order-alert").show(); event.preventDefault(); //Create the Array var productArray = []; //Get reference to the product clicked var stockCode = $(this).closest('li').find('.stock_code').html(); //Get reference to the quantity selected var quantity = $(this).closest('li').find('.order_amount').val(); var item = stockCode + ":" + quantity; var itemCheck = stockCode + ":"; if(quantity == 0){ console.log("Quantity must be greater than 0") }else{ //If no Cookie exists, create one and add the Array if ($.cookie('order_cookie') === undefined) { console.log("CREATE NEW COOKIE"); //Add items to Array productArray.push(item); //Add Array to Cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); //If the Cookie already exists do this } else { productArray = JSON.parse($.cookie('order_cookie'));//get ref to array if(productArray.indexOf(itemCheck)!= -1){//It exists so update qty console.log("EXISTS... updating item: " + itemCheck); //var index = productArray.indexOf(item); //var update = productArray[index].split(":"); //var name = update[0]; //var oldQty = update[1]; //console.log(name + ":" + oldQty); //productArray[index] = item; }else{//It does not exist, so add to array console.log("Does not exist... adding new item: " + item); //Append items onto the Array productArray.push(item); } //Update the Cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); console.log($.cookie('order_cookie')); } //Display the number of items in the Array in the Order Box $('#order_counter').html(productArray.length); } }); I suppose the real question I am asking here, is if it is possible to search the array for a subString - containing productname: ??

  • Including different code for other home screen replacement screens

    - by radicam2
    I have put together a Skin for OpenHome but have since ran across AHome code for their IPhone theme and was wondering that if I included for AHome their Dock_Bg or widget_drawer among other things which is not on OpenHome that the Launcher for the respective screen replacement would just call the items it uses.I want to keep the mb as low as I can but reach more handsets.I can just make seperate ones but see many that include even Freshface as well as OpenHome and AHome.

  • how a thread can signal when it's finished?

    - by Kyle
    #include <iostream> #include <boost/thread.hpp> using std::endl; using std::cout; using namespace boost; mutex running_mutex; struct dostuff { volatile bool running; dostuff() : running(true) {} void operator()(int x) { cout << "dostuff beginning " << x << endl; this_thread::sleep(posix_time::seconds(2)); cout << "dostuff is done doing stuff" << endl; mutex::scoped_lock running_lock(running_mutex); running = false; } }; bool is_running(dostuff& doer) { mutex::scoped_lock running_lock(running_mutex); return doer.running; } int main() { cout << "Begin.." << endl; dostuff doer; thread t(doer, 4); if (is_running(doer)) cout << "Cool, it's running.\n"; this_thread::sleep(posix_time::seconds(3)); if (!is_running(doer)) cout << "Cool, it's done now.\n"; else cout << "still running? why\n"; // This happens! :( return 0; } Why is the output of the above program: Begin.. Cool, it's running. dostuff beginning 4 dostuff is done doing stuff still running? why How can dostuff correctly flag when it is done? I do not want to sit around waiting for it, I just want to be notified when it's done.

  • Why does passing arguments to the command in an env invocation not work?

    - by timdisney
    I have a shell script to run node with some arguments like so: #!/usr/bin/env node --harmony_proxies ... This works fine under OS X but in Ubuntu it errors with: /usr/bin/env: node --harmony_proxies: No such file or directory Node is definitely installed and on the PATH since if I remove the --harmony_proxies flag it works fine. Is there some different way of passing arguments when using env in Ubuntu?

  • Handling macro redefinition without modifying .h files ... C / C++ language

    - by user310119
    Background: Let assume that I have two header files a.h and b.h. a.h contains: #define VAR 1 b.h contains: #define VAR 2 Note: The name of both of the macro is same. Let say I have some file myFile.c which includes both of the header files i.e. a.h and b.h. When I try to access VAR, I get a redefinition error of VAR. In order to resolve this problem, I inserted #ifndef VAR statement in both a.h and b.h files to prevent this error. a.h file becomes #ifndef VAR #define VAR 1 #endif b.h file becomes #ifndef VAR #define VAR 2 #endif Note: The header file can contain multiple macros, not just one macro. Problem: Let's assume that a.h and b.h files are obtained from third party library. These files don't contain #ifndef VAR statement. I am not allowed to change their header files. Can I resolve macro 'VAR' redefinition error in myFile.c or myFile.cpp file which uses VAR macro? I know I #undef VAR can be used to undefine a macro VAR. How can I selectively include VAR later in my program? i.e. on line 10 of myFile.c code I should be able to refer to VAR definition from a.h file, on line 15 of my code I should be able to refer to VAR from b.h file and on line 18 again I should be able to refer to VAR from a.h file. In short, am I able to do macro polymorphism ? Given a name of header file, it should refer to macro definition present in that file. I thought of using namespace trick to resolve an issue. Define first header file in namespace first and second header file in namespace second. I tried defining two namespaces. First namespace contains #include a.h and second namespace contains b.h. However, namespace trick does not work with macro. When I tried to access firstns::VAR, compiler reports an error message. Can you please suggest some way?

  • Selecting count(*) while checking for a value in the results

    SELECT COUNT(*) as Count, IF(sch.HomeTeamID = 34,true,false) AS Hawaii FROM schedule sch JOIN schools s ON s.ID = 83 WHERE (sch.HomeTeamID = 83 OR sch.AwayTeamID = 83) AND sch.SeasonID = 4 I'm trying to use count() to simplify my result but also include a field that represents wether any of the results' specific column contained a certain value. Is this possible? I'd basically like a row response with all the info I need.

  • How to deploy an application with firewall permissions on Mac?

    - by user264878
    I've bundled a jar file as a mac application using jar bundler. I'm now trying to create an installer for this app so that: 1) The application will be placed in the applications folder 2) The application is added to the list of permissible apps in Mac Application Level Firewall Also, I have several example files I would like to include with this application - what is the best way to make these available to the user. Someone suggested I have the mpkg file launch a dmg file which would contain these files, but this seems circuitous. Thanks

    Is it possible to have a pdf file that asks a user a set of questions and then writes their answers to a file, then next time it is viewed loads those answers as default values? I know pdfs can include javascript and have figured out how to add javascript to a pdf with iText (http://itextpdf.com/) but don't know how to prompt for user input or write to a file from inside the pdf. Any help would be appreciated.
