  • php json encode

    - by hafizan
    This below output come from php json_encode.What we see here is 0849 is twice.Since javascript only use sn to get value why we need the "0" value.The main problem is speed execution. If 800 kb data might can be reduce to 400 kb {"success":"true","total":968,"data":[{"0":"0849","sn":"0849" }] If no solution i have to make a script to filter in json_encode so no need twice data transter.

  • iphone uiwebview inital white view

    - by BahaiResearch.com
    My app's main view has a uiwebview. It is white for a split second before it has time to render the HTML the app generates. Is there a way to make the uiwebview black, or another color, before it renders? The flash of white isn't part of my plan for a smooth visual transition. Objective-C or MonoTouch answers are fine, I am bi-lingual.

  • How do I implement multiple kinds of an object in OOP?

    - by Jeremy Rudd
    I have multiple kinds of an object, say Car for example. Do I have each kind in an inherited class/subclass of Car? Do I place these under a cartype namespace so as not to mess up the main namespace? Then later when I need an array of cars, should I declare it as var currentCars():Car or var currentCars():Object? Would the former support any subclass of Car?

  • C array assignment and indexing with similar variable.

    - by Todd R.
    Hello! I apologize if this has been posted before. Compiling under two separate compilers, BCC 5.5 and LCC, yields 0 and 1. #include <stdio.h> int main(void) { int i = 0, array[2] = {0, 0}; array[i] = ++i; printf("%d\n", array[1]); } Am I to assume not all compilers evaluate expressions within an array from right to left?

  • Help with css selector for jquery

    - by NachoF
    I have this wordpress blog that has many pages with subpages that dropdown on hover.... the thing is, I dont want the pages that you hover to link to anything unless they dont have any ul with many anchors inside so just the subpages will have a href different than "#" So basically Im hacking my way through this with some simple javascript. jQuery(document).ready(function(){ jQuery("#menus li > a").attr("href","#"); }); This is selecting every a.. and I dont want that... I just want the anchors that are main pages, not subpages... heres the html so maybe you can think of a better way to select this. Ill explain first the structure is an ul with many li that have an anchor inside if the li also has a ul inside then those are subpages that will appear on hover. hence the initial anchor should have href="#" if there is no ul inside the li then the li a should keep its href. <ul id="menus"> <li> <a href="somelink">Main Page</a> //href should be changed to # <ul> <li> <a href="somelink2/">Subpage1</a> </li> <li> <a href="somelink3">Subpage2</a> </li> </ul> </li> <li> <a href="somelink">MainPage-with-no-subpages</a> //href should not be changed </li> <li> <a href="somelink4">MainPage</a> //href should be changed to # <ul> <li> <a href="somelink5">Subpage</a> </li> <li> <a href="somelink6">Subpage</a> </li> </ul> </li> </ul>

  • Static lock in Python?

    - by roddik
    Hello. I've got the following code: import time import threading class BaseWrapper: #static class lock = threading.Lock() @staticmethod def synchronized_def(): BaseWrapper.lock.acquire() time.sleep(5) BaseWrapper.lock.release() def test(): print time.ctime() if __name__ is '__main__': for i in xrange(10): threading.Thread(target = test).start() I want to have a method synchronized using static lock. However the above code prints the same time ten times, so it isn't really locking. How can I fix it? TIA

    I have the following input to a perl script and I wish to get the first occurrence of NAME="..." strings in each of the ... structures.

  • Quick question about open_basedir

    - by Gio
    Hello, On my server, I have following setting: open_basedir /home/ :/usr/lib/php :/usr/local/lib/php :/tmp/ :/usr/local/ :/usr/bin Now, I am little bit confused about ending / in the / home / setting, does that mean that all subfolders inside home have same rights? or does it mean that only home files can be accessed? So, basically what is the main difference between: /home/ and /home With example if possible Thank you in advance.

  • How can I catch all ajax requests in javascript ?

    - by Annan
    Is it possible to have a global event handler for ajax requests that automatically gets called when any ajax request returns ? I'm interested in this because I'm making a greasemonkey script for an ajax site. In previous scripts I either ran the main function every few seconds or overwrote parts of the site's javascript, both things that are messy.

  • User control or custom control for this design?

    - by m0s
    If I want to create a button control like that, is it supposed to be a User Control or a Custom Control? I am not sure maybe something else? Ideally I want to be able style/animate the main button and the inner button separately; also obviously Ill need to process their events separately. These buttons will be created at run-time and Ill need to set the icons dynamically.

  • Python: how to inherite and override

    - by Guy
    Consider this situation: I get an object of type A which has the function f. I.e: class A: def f(): print 'in f' def h(): print 'in h' and I get an instance of this class but I want to override the f function but save the rest of the functionality of A. So what I was thinking was something of the sort: class B(A): .... def f(): print 'in B->f' and the usage would be: def main(a): b = B(a) b.f() #prints "in B->f" b.h() #print "in h" How do you do such a thing?

  • Value object or not for 3d points ?

    - by Stefano Borini
    I need to develop a geometry library in python, describing points, lines and planes in 3d space, and various geometry operations. Related to my previous question. The main issue in the design is if these entities should have identity or not. I was wondering if there's a similar library out there (developed in another language) to take inspiration from, what is the chosen design, and in particular the reason for one choice vs. the other.
