  • how do I assign a variable to a returned response in jQuery

    - by netrox
    I wanted to assign a returned value (just text) to a variable in jQuery. I wrote this: var hm=22; $.ajax({ type: "GET", url: "ajax_check_match.php", dataType: "text", success:callback }); function callback(data, status) { // assign ajaxed value to cm variable cm=data; if (hm != cm) { dosomething(); } } But it fails every time. Why is that the cm variable keeps getting undefined when it sends request. I set the php file to return 1 and it still says undefined. I opened ajax_check_match.php in browser and I see "1". I didn't see the point of using XML or JSON since a simple number would suffice. Or do I have to use XML/JSON?

  • Simulating C-style for loops in python

    - by YGA
    (even the title of this is going to cause flames, I realize) Python made the deliberate design choice to have the for loop use explicit iterables, with the benefit of considerably simplified code in most cases. However, sometimes it is quite a pain to construct an iterable if your test case and update function are complicated, and so I find myself writing the following while loops: val = START_VAL while <awkward/complicated test case>: # do stuff ... val = <awkward/complicated update> The problem with this is that the update is at the bottom of the while block, meaning that if I want to have a continue embedded somewhere in it I have to: use duplicate code for the complicated/awkard update, AND run the risk of forgetting it and having my code infinite loop I could go the route of hand-rolling a complicated iterator: def complicated_iterator(val): while <awkward/complicated test case>: yeild val val = <awkward/complicated update> for val in complicated_iterator(start_val): if <random check>: continue # no issues here # do stuff This strikes me as waaaaay too verbose and complicated. Do folks in stack overflow have a simpler suggestion?

  • Does PHP Try Catch freezes the page?

    - by serhio
    I have the following code function displaySomeFeeds($urls, $keywords = NULL) { error_reporting(E_ALL ^ E_WARNING ^ E_NOTICE); echo "<ul>"; foreach ($urls as $url) { try { displayFeed($url, $keywords, NULL, false); } catch(Exception $e) { //echo "Error when obtaining news from '$url': " .$e->getMessage(); } } echo "</ul>"; } When I use it with Try Catch, the pages loads very, very, very slow. When I use it without Try/Catch the pages loads normally, but with error messages. Could I ammeliorate the time of response with Try/Catch?

    - by Max
    I have a game with a big raster map Now we are using jpeg (4900x4200) And durring the game we need to scroll through this map. We use the following: Class Map extends mx.containers.Canvas and mx.controls.Image on it In constructor we have: public function Map() { super(); image.source = ResourceManager.interactiveManager.map;//big image addChild(image); ...... } for scrolling we are use: if(parentAsCanvas==null){ parentAsCanvas = (parent as Canvas); } parentAsCanvas.verticalScrollPosition = newX; parentAsCanvas.horizontalScrollPosition = newY; In windows, we have very good performance. In Linux and Mac in flashplayer we have a good performance too. But in browsers performance is quite slow! What can we do to resolve it?

  • jquery - loose click() event after ajax call ???

    - by niczoom
    At the following webpage liamharding.com/pgi.php I have an option panel on the left side of the page which opens and close's upon clicking the panels 'arrow', this works fine until you select a market (for testing use one of the 'Random Walk' markets and click 'Show/Refesh Graphs'), this then makes an ajax call using get_graph(forexName, myCount, divIsNew) function. Once this call is completed a graph(s) is displayed and then my options panels click() event does not work? The ajax call returns the data in a variable ajax_data, the problem happens when I perform the following code var jq_ajax_data = $("<div/>").html(ajax_data); . I need to wrap it in a so I can extract data from it using jQuery. If this line of code is commented out the click() event works fine ?? Hope somebody can help, I have spent a lot of time but cant find what the problem is.

  • Dynamically created image doesn't show when <img>'s src is refreshed to point to it

    - by Obay
    Hello, I have a javascript function generateGraph() { ... jQuery.get('chart.php?month='+month+'&year='+year); document.getElementById('graph').src = 'charts/'+month+'_'+year+'.png'; ... } which is called onChange. It basically creates, if not exists, or refreshes if already exists, a PNG image (using the first line above) and supposedly displays the generated image (using the second line above). The first line works, but the second one doesn't. Meaning, the image is generated, but the second line can't display the image, unless the page is reloaded, or if the image being referred to already existed before the page was loaded (meaning the 1st line just "refreshed" the image) Any ideas as to why this is and how to fix it? Thanks much for your help in advance!

    Hi All, I have been trying to call a C function that has the following signature int changeFoo(L_TCHAR* pszFileSrc){....} in my JNI call my method looks like this: JNIEXPORT jint JNICALL Java_com_me_L_AFoo (JNIEnv * env, jclass jclass, jstring pSrc) { jint retValue = -100; retValue = changeFoo(pSrc); return retValue; } I get the following error in visual studio.

  • Jasper Reports - Add one day to a Date Parameter

    - by Templar
    I'm creating a Jasper report that includes the following parameters: DATESTART (Date) DATEEND (Date) These parameters indicate a date range for a field called DATECREATED (Timestamp) which includes times. I would like the date range to be INCLUSIVE, that is, if I filter for "Jan 1, 2009" to "Jan 31, 2009", any DATECREATED value on Jan 31, 2009 (such as "Jan 31, 2009 15:00") will be included in the report. When I used Crystal Reports in the past, I used the DATEADD function to create a filter expression like the following: {DATECREATED} >= {DATESTART} and {DATECREATED} < DATEADD("d", 1, {DATEEND}) (I realize that this isn't syntactically correct, but you get the idea.) Is there any way to do something similar in Jasper Reports?

  • Php PEAR, Database Abstraction & Factory Methods

    - by pws5068
    I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a special-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: 1.) Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? 2.) Can PEAR interface with the MySqli prepared statements I currently use? 3.) Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) 4.) Will it slow down my site once I have a significantly large member base?

  • A hooked DirectX 9 program crashes on window resize, texture related.

    - by Ben
    I'm using EasyHook and SlimDX to overlay some graphics using SlimDX's Sprite and Texture classes. When I resize windows some programs fine, but others will crash - Winamp's MilkDrop 2 gives me an ambiguous memory error for example. I expect this is due to the after market Texture I created. The question is what VTable function should I hook and/or how/when do I dispose and recreate the Texture? Reset perhaps? If it isn't obvious I don't know much about DirectX.

  • Setting up functional Tests in Flex

    - by Dan Monego
    I'm setting up a functional test suite for an application that loads an external configuration file. Right now, I'm using flexunit's addAsync function to load it and then again to test if the contents point to services that exist and can be accessed. The trouble with this is that having this kind of two (or more) stage method means that I'm running all of my tests in the context of one test with dozens of asserts, which seems like a kind of degenerate way to use the framework, and makes bugs harder to find. Is there a way to have something like an asynchronous setup? Is there another testing framework that handles this better?

  • Is the javaScript not part of the DOM?

    - by DKinzer
    Why is it that scripts can still function even after the code used to create them is removed from the DOM? I ran into a situation where I wanted to prevent a broken script from running (@see my post). In my attempt to come up with a solution I wrote an extension with the following line (just to see what would happen). //doc is passed here because this script is running as a firefox extension outside //of the document context. $('script', doc).remove(); I assumed that this would remove all the scripts from the DOM, which it did, and that therefore no scripts would run on the page, which is not the case. I would love to know more about what's behind this behavior.

  • How do I dynamically name objects in Java?

    - by hatboysam
    Let's say I needed to make a series of String[] objects. I know that if i wanted to make a string array called "test" to hold 3 Strings I could do String[] test = new String[3]; But let's say I needed to make a series of these arrays and I wanted them to be named, 1,2, 3, 4, 5... etc. For however many I needed and I didn't know how many I'd need. How do I achieve a similar effect to this: for (int k=0; k=5; k++){ String[] k = new String[3]; } Which would created 5 string arrays named 1 through 5. Basically I want to be able to create array objects with a name detemined by some other function. Why can't I seem to do this? Am I just being stupid?

  • Add bytes to binary file using only PHP?

    - by hurmans
    I am trying to add random bytes to binary (.exe) files to increase it size using php. So far I got this: function junk($bs) { // string length: 256 chars $tmp = 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'; for($i=0;$i<=$bs;$i++) { $tmp = $tmp . $tmp; } return $tmp; } $fp = fopen('test.exe', 'ab'); fwrite($fp, junk(1)); fclose($fp); This works fine and the resulting exe is functional but if I want to do junk(100) to add more size to the file I get the php error "Fatal error: Allowed memory size..." In which other way could I achieve this without getting an error? Would it be ok to loop the fwrite xxx times?

  • Server-initiated Rendering: EJB -> FacesContext?

    - by egbokul
    I've already asked this question on the Icefaces forum, but meanwhile I realized that this is a more generic problem. I'd like to update parts of a JSF page when I get a message in my MDB. The problem is, how do I get the FacesContext from the EJB container? In the message processing function FacesContext.getCurrentInstance() returns null. I've also tried to make a JSF managed bean be a MDB, but I couldn't (it seems you can't have both in the same class?). Since I'm a beginner in the JSF world I'm kind of stuck now. Is there a way to make it work? (Glassfish v3 + Netbeans 6.8, JSF2 + Icefaces 2.0 alpha2)

  • Constructing T-SQL WHERE condition at runtime

    - by Nickson
    I would like to implement a search function where a user passes all the arguments to the "WHERE" clause at runtime. For example in query below, SELECT Col1, Col2, Col3, Col4 FROM MyTable WHERE Col2 = John 1.Now what i want is to give the user a dropdownlist of columnns such that the user selects a column to search by at runtime Also instead of precoding Col2 = John, i want the user to choose their own operator at runtime(such as choosing between =, <, <, <, LIKE, IN) i basically want to contruct a query like SELECT Col1, Col2, Col3, Col4 FROM MyTable WHERE (@FieldToSearchBy e.g Col3, @OperatorToUserInSearach e.g LIKE, @ValueToSearch e.g John) I want to pass @FieldToSearchBy, @OperatorToUserInSearach, @ValueToSearch) as user specified parameters at runtime I want to do this with a TableAdpter like in this example http://www.codeproject.com/KB/database/TableAdapter.aspx

  • Disallow using comma operator

    - by RiaD
    I never use the comma operator. But sometimes, when I write some recursions, I make a stupid mistake: I forget the function name. That's why the last operand is returned, not the result of a recursion call. Simplified example: int binpow(int a,int b){ if(!b) return 1; if(b&1) return a*binpow(a,b-1); return (a*a,b/2); // comma operator } Is it possible get a compilation error instead of incorrect, hard to debug code?

  • jQuery TriggerHandler doesn't trigger keyup event set via live

    Why i can't trigget handler via triggerHandler if it's was bound via live? For example form.find('#code').live('change keyup',function(){ process_code($(this)); }); Startups after window load: /* Triggers */ if(checkCookie('banner_ready_code')) { $('#form').find('#code').triggerHandler('keyup'); } Nothing happens... If i'm binding simply by .change or .keyup, triggerHandler is working properly as intended. If it's bug, where to report it. Too lazy :) If not, please explain. :)

  • MDX query- How do I use a member property?

    I'm a complete newb to MDX / OLAP, "data warehousing" in general. I have the following MDX query and would like my results to display the month's number (1 = January, 12 = December). Luckily, the cube creator create a member property named "Month Number Of Year" When I try to run the query, I get the following... "Query (4, 8) The function expects a tuple set expression for the 1 argument. A string or numeric expression was used." Any suggestions for fixing this? Thanks!
