    - by justjoe
    hi, right now, i code custom wordpress theme and testing it in xampp windows XP on apache server. But as long as i concern, there's no wp build-in function to identify the code environment.

  • jQuery: I need something like ':visible' that works even if the parent is display=none

    - by Master Morality
    I have a list where elements are hidden for multiple reasons, each corresponding to a css class i.e: <style> .filteredOut { display: none; } .somethingElse { display : none; } ... </style> I want to apply alternating css classes via .filter(':even').addClass('even') but only to classes that are visible. The problem is that the parent is hidden when this happens so .filter(':visible') returns 0 elements. I need something like .filter(':visibileEventIfParentIsNot') Further more, I'd rather not have to call a function with this in it every time I call a function that changes what's visible in a list. This may be a pipe dream, but is there a way to do this ala live() or something similar? I'm open to off the wall ideas.

  • using setSfGuardUser() to save the current user in the model

    - by user334017
    My application makes use of the sfGuardUser plugin. One of my tables has a relation onto the sf_guard_user table so there is a corresponding setSfGuardUser() function in the base model. From Actions.class.php, I am attempting to set the current user into the object using this function, (Which I then save in the database). my attempt: ->setSfGuardUser($this->getUser()); //called from inside Actions.class.php this throws an error: Couldn't call Doctrine_Core::set(), second argument should be an instance of Doctrine_Record or Doctrine_Null when setting one-to-one references. ...# at Doctrine_Record->coreSetRelated('sfGuardUser', object('myUser')) Which makes me think that getUser() is not returning a sfGuardUser object, though I don't know how to check this. Can anyone offer any insight?

  • Using Classes / OOP in PHP

    - by Alex Demchak
    I'm pretty proficient with PHP, outside of OOP - which I am just now starting to jump in to. I've been watching videos and reading tutorials, but they are all still pretty confusing... If I have FILE 1 (class.time.php) class Time { function GetTime(){ $time = date('H:i:s'); printf($time); } } and then in a nother php page I've got FILE 2 (page.php) I can do include('class.time.php'); and then anywhere in this page I can then do $time = new Time; //Calling the class and setting the class to a variable $time->GetTime(); //This is BASICALLY saying (run the 'GetTime' function in the 'Time Class' My main question is, is the comment above (This is BASICALLY saying.....) correct? or is there a better way to think of it?

  • Scala : reference is ambiguous (imported twice)

    - by tk
    I want to use a method as a parameter of another method of the same class. I have a class and objects which are companions: class mM(var elem:Matrix){ //apply a function on a dimension rows (1) or cols (2) def app(func:Iterable[Double]=>Double)(dim : Int) : Matrix = { ... } //utility function def logsumexp(): Double = {...} } object mM{ def apply(elem:Matrix):mM={new mM(elem)} def logsumexp(elem:Iterable[Double]): Double ={ this.apply(elem.asInstanceOf[Matrix]).logsumexp() } } Normally I use logsumexp like this mM(matrix).logsumexp but if want to apply it to the rows I can't use mM(matrix).app(mM.logsumexp)(1), I get the error: error: reference to mM is ambiguous; it is imported twice in the same scope by import mM and import mM What is the most elegant solution ? Should I change logsumexp() to another class ? Thanks,=)

  • Javascript: Display message when user leaves site

    - by Brian Rasmusson
    Hi, I'm looking for a way to display a message to the user if he leaves my site after only viewing one page. I found this (http://www.pgrs.net/2008/1/30/popup-when-leaving-website) clever solution, but it has a few flaws: staying_in_site = false; Event.observe(document.body, 'click', function(event) { if (Event.element(event).tagName == 'A') { staying_in_site = true; } }); window.onunload = popup; function popup() { if(staying_in_site) { return; } alert('I see you are leaving the site'); } It displays the message also when refreshing the page or using the back button. Do you know a better solution or how to fix it in the above code? I'm no javascript master :) My intention is to add the code on very specific landing pages only, and display the message when people leave the page without downloading my trial software or reading other pages on my site.

  • Jquery Scrolling

    - by Rich - Pixel Vector
    I have implemented the following code from this page: http://tympanus.net/codrops/2010/06/02/smooth-vertical-or-horizontal-page-scrolling-with-jquery/ $(document).ready(function() { $('ul.navone li a, ul.navtwo li a,a.toplink, a.bodylink').bind('click',function(event){ var $anchor = $(this); $('html, body, header').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 1500,'easeInOutExpo'); event.preventDefault(); }); }); This all works correctly. However, in my layout I have a fixed header div (i.e. it stays in place when the user scrolls). Therefore I need to set an offset for the scrolling script of 117 pixels. How do I do this please?

  • Do (statically linked) DLLs use a different heap than the main program?

    - by happy_emi
    I'm new to Windows programming and I've just "lost" two hours hunting a bug which everyone seems aware of: you cannot create an object on the heap in a DLL and destroy it in another DLL (or in the main program). I'm almost sure that on Linux/Unix this is NOT the case (if it is, please say it, but I'm pretty sure I did that thousands of times without problems...). At this point I have a couple of questions: 1) Do statically linked DLLs use a different heap than the main program? 2) Is the statically linked DLL mapped in the same process space of the main program? (I'm quite sure the answer here is a big YES otherwise it wouldn't make sense passing pointers from a function in the main program to a function in a DLL). I'm talking about plain/regular DLL, not COM/ATL services EDIT: By "statically linked" I mean that I don't use LoadLibrary to load the DLL but I link with the stub library

  • How to check whether iterators form a contiguous memory zone?

    - by Vincent
    I currently have the following function to read an array or a vector of raw data (_readStream is a std::ifstream) : template<typename IteratorType> inline bool MyClass::readRawData( const IteratorType& first, const IteratorType& last, typename std::iterator_traits<IteratorType>::iterator_category* = nullptr ) { _readStream.read(reinterpret_cast<char*>(&*first), (last-first)*sizeof(*first)); return _readStream.good(); } First question : does this function seem ok for you ? As we read directly a block of memory, it will only work if the memory block from first to last is contiguous in memory. How to check that ?

  • jquery specific show buttons on hover

    - by bob
    I have an application creating a bunch of divs through a loop. Each div has the class "product" so it looks like <div class="product"> !.....stuff here ....! <div class="show_on_hover">...buttons here... </div> </div> so there are about 12 of these same divs per page. I would like to hover over a specific one and show the specific "show_on_hover" div which is initially set to display:none. $('.product').hover(function() { $(.show_on_hover).show(); }, function () { $(.show_on_hover).hide(); } ); That is what I have so far but it will show ALL of the .show_on_hovers on the page so I am wondering how to get only the specific one you have moused over to show. This effect is seen on youtube when you mouseover any of the comments, and some comment tools pop up. Thanks!

  • How can I make a recursive version of my iterative method?

    - by user247679
    Greetings. I am trying to write a recursive function in Java that prints the numbers one through n. (n being the parameter that you send the function.) An iterative solution is pretty straightforward: public static void printNumbers(int n){ for(int i = 1; i <= n; i++){ System.out.println(i); i++; } As a novice programmer, I'm having troubles figuring out how a recursive version of this method would work. Any bright ideas? Thanks for reading my problem!

The reason for that is that I need to have individual popup tooltips on mouse-over each table row. Many Thanks in advance for any kind of help or suggestions!

  • Execute js on DOMContentLoaded in ff-extension

    - by ArtWorkAD
    Hi, I want to enable jQuery for my extension. So I want to do something similar to $(document).ready(function() { // put all your jQuery goodness in here. }); So I came up with var app = window.document.getElementById('page'); app.addEventListener("DOMContentLoaded", onPageLoad, false); function onPageLoad(){ alert("test"); } But this does not work at all. Any ideas how to call onPageLoad each time DOM content is reloaded?

  • How to use $.get data to replace certain elements in a webpage?

    - by Jack Ha
    I'm using jQuery 1.4.2 to navigate smoothly between similar webpages (in ff3). When clicking on a link, a javascript script should load the new html, filter out the right elements and replace them on the current page. It looks like the $(htmlcode) does not do the thing I expected. The actions below work when loading the page directly, but when using the $.get I have the following problems: the find function seems only to look inside a div element called id="page", which is inside the body element one of the elements has <script>...</script>, but the <script>...</script> is not present in the DOM of $(htmlcode). Anybody knows how to solve this? $.get( url, function(responseText, textStatus, xmlHttpRequest) { alert($(responseText).find("#header")); // works, #header is inside div#page alert($(responseText).find("#header").html()); // displays content, but WITHOUT the <script>...</script> alert($(responseText).find("title")); // does not work, title is outside div#page } );

  • Converting keys of an array/object-tree to lowercase

    - by tstenner
    Im currently optimizing a PHP application and found one function being called around 10-20k times, so I'd thought I'd start optimization there. function keysToLower($obj) { if(!is_object($obj) && !is_array($obj)) return $obj; foreach($obj as $key=>$element) { $element=keysToLower($element); if(is_object($obj)) { $obj->{strtolower($key)}=$element; if(!ctype_lower($key)) unset($obj->{$key}); } else if(is_array($obj) && ctype_upper($key)) { $obj[strtolower($key)]=$element; unset($obj[$key]); } } return $obj; } Most of the time is spent in recursive calls (which are quite slow in PHP), but I don't see any way to convert it to a loop. What would you do?

  • jQuery: add border on hovered element but NOT parents

    - by John Isaacks
    I have this code: var originalBorder = container.css("border"); container.hover(function(event) { event.stopPropagation(); $(this).css("border", "1px solid "+options.color); },function(){ $(this).css("border", originalBorder); }); Which I am using to add a border to the currently hovered element. However for example if a span is inside a div they are both getting borders. I only want to target the span. I thought that adding event.stopPropagation() would do the trick (this is what I would do in Flex, which is what I am more used to) but I guess this is a live event which I dont even understand what that means. So basically how can target the youngest element without triggering the parents? Thanks!!

  • C++ static virtual members?

    - by cvb
    Is it possible in C++ to have a member function that is both static and virtual? Apperantly, there isn't a straight-forward way to do it (static virtual member(); is a complie error), but at least a way to acheive the same effect? I.E: struct Object { struct TypeInformation; static virtual const TypeInformation &GetTypeInformation() const; }; struct SomeObject : public Object { static virtual const TypeInformation &GetTypeInformation() const; }; It makes sence to use GetTypeInformation() both on an instance (object->GetTypeInformation()) and on a class (SomeObject::GetTypeInformation()), which can be useful for comparsions and vital for templates. The only ways I can think of involves writing two functions / a function and a constant, per class, or use macros. Any other solutions?
