  • How do I get jquery & mootools to play nice?

    - by Vic
    I've been using Mootools 1.2.4 as my JS framework of choice. I've added Checkout by Amazon to one of my pages, and they inject jQuery 1.2.6 into the page and messes up my dollar function (among other things). I have control over Mootools, but not jQuery. I would rather not rewrite my existing code to accomodate jQuery since Checkout by Amazon was an afterthought and plug-in element. Any thoughts or suggestions are recommended. Thanks!

  • regular expressions for class name

    - by user576701
    i need a regular expressions string to get all anchor tags in a page with a specific css class name, in c#/vb.net this is what i got so far "<a.*?href=""(.*?)"".*?>(.*?)</a>" but my attempts to add "class=name" isnt working, also is it possible to find links where the class name appears either before or after the href with one expression ? i am familiar with 3rd party html libraries, but thats an overkill for what i have in mind, so is the webbrowser control.

  • Detecting if a file is binary or plain text?

    - by dr. evil
    How can I detect if a file is binary or a plain text? Basically my .NET app is processing batch files and extracting data however I don't want to process binary files. As a solution I'm thinking about analysing first X bytes of the file and if there are more unprintable characters than printable characters it should be binary. Is this the right way to do it? Is there nay better implementation for this task?

  • File Uploading inWeb pages

    - by Jibu P C_Adoor
    Hii, Any one knows how to upload files to the physical location of the server. It is possible using file upload control that i know. But i want to avoid the external postbacking of the page. For e.g exactly like what in the yahoo mail did. In yahoo mail latest version if you attach a file that won't post back and attach that file in to server. What is the technology behind that?

  • How dangerous is e.preventDefault();, and can it be replaced by keydown/mousedown tracking?

    - by yc
    I'm working on a tracking script for a fairly sophisticated CRM for tracking form actions in Google Analytics. I'm trying to balance the desire to track form actions accurately with the need to never prevent a form from not working. Now, I know that doing something like this doesn't work. $('form').submit(function(){ _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')) }); The DOM unloads before this has a chance to process. So, a lot of sample code recommends something like this: $('form').submit(function(e){ e.preventDefault(); var form = this; _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')); //...do some other tracking stuff... setTimeout(function(){ form.submit(); }, 400); }); This is reliable in most cases, but it makes me nervous. What if something happens between e.preventDefault();and when I get around to triggering the DOM based submit? I've totally broken the form. I've been poking around some other analytics implementations, and I've noticed something like this: $('form').mousedown(function(){ _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')); }); $('form').keydown(function(e){ if(e.which===13) //if the keydown is the enter key _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')); }); Basically, instead of interrupting the form submit, preempting it by assuming that if someone is mousing down or keying down on Enter, than that form is submitted. Obviously, this will result in a certain amount of false positives, but it completely eliminates use of e.preventDefault();, which in my mind eliminates the risk that I might ever prevent a form from successfully submitting. So, my question: Is it possible to take the standard form tracking snippet and prevent it from ever fully preventing the form from submitting? Is the mousedown/keydown alternative viable? Are there any submission cases it may miss? Specifically, are there other ways to end up submitting besides the mouse and the keyboard enter? And will the browser always have time to process javascript before beginning to unload the page?

    I'm writing javascript code for a web emulator containing function keys. The user is able to press keyboard function keys to process something in the emulator, I used stopPropagation and preventDefault javascript function to stop/cancel browsers invoking their function key shortcut (e.g. F1 will invoke Firefox to open its help page) and the code works fine under Firefox and Chrome. But Opera didn't work. I'm using latest Opera 10.5 here. Can anyone help ?

  • sigwait in Linux (Fedora 13) vs OS X

    - by Silas
    So I'm trying to create a signal handler using pthreads which works on both OS X and Linux. The code below works on OS X but doesn't work on Fedora 13. The application is fairly simple. It spawns a pthread, registers SIGHUP and waits for a signal. After spawning the signal handler I block SIGHUP in the main thread so the signal should only be sent to the signal_handler thread. On OS X this works fine, if I compile, run and send SIGHUP to the process it prints "Got SIGHUP". On Linux it just kills the process (and prints Hangup). If I comment out the signal_handler pthread_create the application doesn't die. I know the application gets to the sigwait and blocks but instead of return the signal code it just kills the application. I ran the test using the following commands: g++ test.cc -lpthread -o test ./test & PID="$!" sleep 1 kill -1 "$PID" test.cc #include <pthread.h> #include <signal.h> #include <iostream> using namespace std; void *signal_handler(void *arg) { int sig; sigset_t set; sigemptyset(&set); sigaddset(&set, SIGHUP); while (true) { cout << "Wait for signal" << endl; sigwait(&set, &sig); if (sig == SIGHUP) { cout << "Got SIGHUP" << endl; } } } int main() { pthread_t handler; sigset_t set; // Create signal handler pthread_create(&handler, NULL, signal_handler, NULL); // Ignore SIGHUP in main thread sigfillset(&set); sigaddset(&set, SIGHUP); pthread_sigmask(SIG_BLOCK, &set, NULL); for (int i = 1; i < 5; i++) { cout << "Sleeping..." << endl; sleep(1); } pthread_join(handler, NULL); return 0; }

    - by Pittor
    Hi, this is my question... I have a compilation(UITableView) of videos from youtube of a particular gender(funny videos, for example) and I want to know if this app will pass the approval process.

  • a good resource or book for architecting object-oriented software

    - by Ygam
    I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

  • Is there a way to flush html to the wire in Sinatra

    - by thismatt
    I have a Sinatra app with a long running process (a web scraper). I'd like the app flush the results of the crawler's progress as the crawler is running instead of at the end. I've considered forking the request and doing something fancy with ajax but this is a really basic one-pager app that really just needs to output a log to a browser as it's happening. Any suggestions?

  • Opening a streaming connection to an HTTP server on iPhone/Cocoa environment?

    - by Paul
    I've been using NSURLConnection to do a HTTP post to establish the connection. I've also implemented the didReceiveData delegagate to process incoming bytes as they become available. As incoming data comes in via didReceiveData, I add the NSData to a data buffer and try parsing the bytesteam if enough data has come in to complete a message segment. I'm having a hard time managing the data buffer (NSMutableData object) to remove bytes that have been parsed to structs. Was curious if there's an easier way. Thanks
