  • Create and define Vector

    - by zdmytriv
    I'm looking for method to create Vector and push some values without defining variable Vector. For example: I have function: public function bla(data:Vector.<Object>):void { ... } this function expects Vector as parameter. I can pass parameters this way var newVector:Vector.<Object> = new Vector.<Object>(); newVector.push("bla1"); newVector.push("bla2"); bla(newVector); Can I do it in one line in Flex? I'm looking for something like: bla(new Vector.<Object>().push("bla1").push("bla2")); I've also tried this: bla(function():Vector.<Object> { var result:Vector.<Object> = new Vector.<Object>(2, true); result.push("bla1"); result.push("bla2"); return result; }); But it complains: 1067: Implicit coercion of a value of type Function to an unrelated type __AS3__.vec:Vector.<Object>... Thanks

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

  • Eval string for wordpress "in_category" workaround outside the loop

    - by fimbim
    In Wordpress you can´t use "in_category" outside the loop, so I created a function that gives me all the categories my article is in and create a "is_category" if statement out of it. I put my function in my "functions.php": function inCatAlt($catID){ $allCats = get_categories('child_of='.$catID); $childCats = 'is_category('.$catID.') '; foreach($allCats as $childCat){ $childCats.= 'or is_category('.$childCat->cat_ID.') '; }; $allchildCats = trim(trim($childCats, 'or ')); return $allchildCats; } and call this in my sidebar, single and so on: echo inCatAlt(13); which gives me this as a string back: "is_category(13) or is_category(16) or is_category(15)" This is exactly what I needed, but now I want to evaluate the string to use it in a if function like this: if(eval(inCatAlt(13))){ do something } But it doesn´t work. Do I evaluate it wrong or what is the problem? If I copy paste the output into the if function it works fine… Thanks in advanced guys. Is my first time asking something here. I´m curious :)

  • (C++) What's the difference between these overloaded operator functions?

    - by cv3000
    What is the difference between these two ways of overloading the != operator below. Which is consider better? Class Test { ...// private: int iTest public: BOOL operator==(const &Test test) const; BOOL operator!=(const &Test test) const; } BOOL operator==(const &Test test) const { return (iTest == test.iTest); } //overload function 1 BOOL Test::operator!=(const &Test test) const { return !operator==(test); } //overload function 2 BOOL Test::operator!=(const &Test test) const { return (iTest != test.iTest); } I've just recently seen function 1's syntax for calling a sibling operator function and wonder if writing it that way provides any benefits.

  • How do C and C++ interpreters bind identifiers to functions

    - by sub
    I'm talking about C and/or C++ here as this are the only languages I know used for interpreters where the following could be a problem: If we have an interpreted language X how can a library written for it add functions to the language which can then be called from within programs written in the language? PHP example: substr( $str, 5, 10 ); How is the function substr added to the "function pool" of PHP so it can be called from within scripts? It is easy for PHP storing all registered function names in an array and searching through it as a function is called in a script. However, as there obviously is no eval in C(++), how can the function then be called? I assume PHP doesn't have 100MB of code like: if( identifier == "substr" ) { return PHP_SUBSTR(...); } else if( ... ) { ... } Ha ha, that would be pretty funny. I hope you have understood my question so far. How do C/C++ interpreters solve this problem? How can I solve this for my own experimental toy interpreter?

  • Solution for using `this` keyword in ajax calls within methods?

    - by dqhendricks
    I am creating a JavaScript class. Some of the methods contain AJAX calls using JQuery. The problem I am comming accross is that I cannot use the this keyword within the AJAX callbacks due to a change in scope. I have come up with a hackey solution, but I am wondering what is the best practice way around this? Here is an example: var someClass = function() { var someElement = $('form'); this.close = function() { someElement.remove(); }; this.query = function() { $.ajax({ url: someurl, success: function() { this.close(); // does not work because `this` is no longer the parent class } }); }; };

  • send datas to php with ajax - Internal Server Error(500)

    - by user1277467
    i try to send my datas to php with ajax but there's strange mistake. this is my ajax script, function deleteData2() { var artistIds = new Array(); $(".p16 input:checked").each(function(){ artistIds.push($(this).attr('id')); }); $.post('/json/crewonly/deleteDataAjax2', { json: JSON.stringify({'artistIds': artistIds}) }, function(response){ alert(response); }); } i think this works correctly but in php side, i face 500 internal server error(500). public function deleteDataAjax2() { $json = $_POST['json']; $data = json_decode($json); $artistIds = $data['artistIds']; $this->sendJSONResponse($artistIds); } Above code is my php. For example, when i try to send $data to ajax, i print my ids in json mode: However, when i try to send $artistIds to ajax side, i gives 500 error why?

  • Call/Ret in x86 assembly embedded in C++

    - by SP658
    This is probably trivial, but for some reason I can't it to work. Its supposed to be a simple function that changes the last byte of a dword to 'AA' (10101010), but nothing happens when I call the function. It just returns my original dword __declspec(naked) long function(unsigned long inputDWord, unsigned long *outputDWord) { _asm{ mov ebx, dword ptr[esp+4] push ebx call SET_AA pop ebx mov eax, dword ptr[esp+8] mov dword ptr[eax], ebx } } __declspec(naked) unsigned long SET_AA( unsigned long inputDWord ) { __asm{ mov eax, [esp+4] mov al, 0xAA ret } }

  • Full and Partial Matching of Sets

    - by jeffrey
    I have several sets of the same type [Y, M, D] and am trying to write a function to search these sets and return an array of the available sets that fit my parameters. ReturnedSets = return_matches(Y,M,D); I want the three parameters of the function return_matches to be optional. Which means any combination of values can be used to return the sets. For example, one could write - return_matches(13,null,2); - and the function would look for all sets that contain [13, anyValue, 2]; I'm writing this in PHP, to allow users to manage dated files on my website, but I'd like to be able to use this function again for other uses. Thanks! edit: (This, or variations of this, is all I can come up with so far... There is something extra that I don't understand, because this function ends up / would not work to return sets that contain y and d, but leaving m arbitrary. if(y == s[0]){ if(m == s[1]){ if(d == s[2]){ print "day match"; } } else {print "month match";} } else {print "year match";} } else {print "no match";}

  • How to drop a sortable block?

    I have a list which is reordered using sortable. I defined a trash can div, and I want to achieve that when the blocks are dropped on this div to get deleted. So far I can't seam to fine the way to fire the drop event, when I release the item gets back to his previous position.

  • JavaScript - Loop over all a tags, add an onclick to each one

    - by tripRev
    I've got a list of links that point to images, and a js function that takes a URL (of an image) and puts that image on the page when the function is called. I was originally adding an inline onlick="showPic(this.getAttribute('href'))" to each a, but I want to separate out the inline js. Here's my func for adding an onclick to each a tag when the page loads: function prepareLinks(){ var links = document.getElementsByTagName('a'); for(var i=0; i<links.length; i++){ var thisLink = links[i]; var source = thisLink.getAttribute('href'); if(thisLink.getAttribute('class') == 'imgLink'){ thisLink.onclick = function(){ showPic(source); return false; } } } } function showPic(source){ var placeholder = document.getElementById('placeholder'); placeholder.setAttribute('src',source); } window.onload = prepareLinks(); ...but every time showPic is called, the source var is the href of the last image. How can I make each link have the correct onclick?

  • Exceptions confusion

    Hi there. I'm trying to build site using OOP in PHP. Everyone is talking about Singleton, hermetization, MVC, and using exceptions. So I've tried to do it like this: Class building whole site: class Core { public $is_core; public $theme; private $db; public $language; private $info; static private $instance; public function __construct($lang = 'eng', $theme = 'default') { if(!self::$instance) { try { $this->db = new sdb(DB_TYPE.':host='.DB_HOST.';dbname='.DB_NAME, DB_USER, DB_PASS); } catch(PDOException $e) { throw new CoreException($e->getMessage()); } try { $this->language = new Language($lang); } catch(LangException $e) { throw new CoreException($e->getMessage()); } try { $this->theme = new Theme($theme); } catch(ThemeException $e) { throw new CoreException($e->getMessage()); } } return self::$instance; } public function getSite($what) { return $this->language->getLang(); } private function __clone() { } } Class managing themes class Theme { private $theme; public function __construct($name = 'default') { if(!is_dir("themes/$name")) { throw new ThemeException("Unable to load theme $name"); } else { $this->theme = $name; } } public function getTheme() { return $this->theme; } public function display($part) { if(!is_file("themes/$this->theme/$part.php")) { throw new ThemeException("Unable to load theme part: themes/$this->theme/$part.php"); } else { return 'So far so good'; } } } And usage: error_reporting(E_ALL); require_once('config.php'); require_once('functions.php'); try { $core = new Core(); } catch(CoreException $e) { echo 'Core Exception: '.$e->getMessage(); } echo $core->theme->getTheme(); echo "<br />"; echo $core->language->getLang(); try { $core->theme->display('footer'); } catch(ThemeException $e) { echo $e->getMessage(); } I don't like those exception handlers - i don't want to catch them like some pokemons... I want to use things simple: $core-theme-display('footer'); And if something is wrong, and debug mode is enabled, then aplication show error. What should i do?

  • Why isnt int pow(int base, int exponent) in the standard C++ libraries?

    - by Dan O
    I feel like I must just be unable to find it. Is there any reason that the c++ pow function does not implement the "power" function for anything except floats and doubles? I know the implementation is trivial, I just feel like I'm doing work that should be in a standard library. A robust power function (ie handles overflow in some consistent, explicit way) is not fun to write.

  • Profiling and Graphics.updateDisplay0()

    - by AD
    I am profiling my BlackBerry application (a game) with the options 'In method only' and 'Time including native method'. Under the 'All methods' node (after a decent run of the game) the single most time consuming function is Graphics.updateDisplay0() with over 50% of the run time spent there. I don't quite know what is the purpose of that function or if I can do anything to reduce its processing time, so if anyone can shed some light on the matter, I would be grateful. Because from what I understand with the 'In method only' option, it means there is some processing within that function. ps. there is no information on that function in the documentation.

  • jQuery Sales Tax

    - by CKallemeres
    Hello everyone! I have created a function (see below) that calculates a 7.5% sales tax. Now I need help doing the following: Have totalTax() take in 2 arguments one for the price and one for the tax. On submit (use the onSubmit event handler to call this function) have the function process the price and the tax by manipulating the arguments you passed in. Have the sales tax on the page update dynamically with what ever the sales tax is that you defined for the function 7.5 percent sales tax: Instead of using .innerHTML use jQuery to access these document elements and write to them: document.getElementById('requestedAmount' ).innerHTML = priceInput; document.getElementById('requestedTax' ).innerHTML = salesTax; document.getElementById('requestedTotal' ).innerHTML = totalAmount; Original Code: <script type="text/javascript"> $().ready(function() { // validate the comment form when it is submitted $("#inputForm").validate(); $("#priceInput").priceFormat({ prefix: '', limit: 5, centsLimit: 2 }); }); function totalTax(){ var priceInput = document.getElementById( 'priceInput' ).value; var salesTax = Math.round(((priceInput / 100) * 7.5)*100)/100; var totalAmount = (priceInput*1) + (salesTax * 1); document.getElementById( 'requestedAmount' ).innerHTML = priceInput; document.getElementById( 'requestedTax' ).innerHTML = salesTax; document.getElementById( 'requestedTotal' ).innerHTML = totalAmount; } </script> <body> <form class="cmxform" id="inputForm" method="get" action=""> <p> <label for="priceInput">Enter the price: </label> <input id="priceInput" name="name" class="required"/> </p> <p> <input class="submit" type="submit" value="Submit" onclick="totalTax();"/> </p> </form> <div>Entered price: <p id="requestedAmount"></p> </div> <div>7.5 percent sales tax: <p id="requestedTax"></p> </div> <div>Total: <p id="requestedTotal"> </p> </div>

THE CODE: In my /Models folder I have product_model.php: <?php class Product_model extends Model { function Product_model() { parent::Model(); } function get_prod_single($product_id) { //This will be a DB lookup ... return 'foo'; //stub to get going } } ?> In my /controllers folder I have product.php: <?php class Product extends Controller { function Product() { parent::Controller(); } function index() { $this->load->model('Product_model'); $product_id = 113; // will get this dynamically $data['product_id'] = $product_id; $data['pn_oem'] = $this->product_model->get_prod_single($product_id); $this->load->view('prod_single', $data); } } ?>
