  • jquery skip list item

    - by steve
    Is there a way for a jQuery function to "skip" an li? Such as Having 3 list items, you click on the 1st one, it calls a next() function, and skips the 2nd li and goes to the 3rd. Current code is here: $('ul.gallery li').click(function() { $(window).scrollTo($(this).next('li'), 800, {easing:'easeOutCirc', axis:'x', offset:-50 } ); }); I want it to skip the immediate li and go to the one after that.

  • jQuery find events handlers registered with an object

    - by ages04
    I need to find which event handlers an object has registered. eg. $("#el").click(function(){...}); $("#el").mouseover(function(){...}); Is there anyway I can use a function to find out that- $("#el") has click and mouseover registered and possibly iterate over the event handlers. If not a jQuery Object can we find this on a plain DOM object?

  • jquery - deciding whether a user is "away"

    - by Phil Jackson
    hi, im doing a little test to check whether the user is "away" (unactive) or not; function away_status(){ $("#away_stat_update").everyTime(1000, function(i) { var number = Number($(this).html()); if( number == 20 ) { // set user as away alert( "user away" ); } if( number > 20 ) { $("*").mousemove(function(e){ $("#away_stat_update").html(0); var number = Number(0); // reset user to being online alert( "user back online" ); }); } $("#away_stat_update").html( number + 1 ); }); $("*").mousemove(function(e){ $("#away_stat_update").html(0); }); } away_status(); the only problem is that when the number is greater than 20 and the mouse is moved it keeps alerting "user back on line" instead of doing it just once. The number is resetting by the way.

  • Design pattern for mouse interaction

    - by mike
    I need some opinions on what is the "ideal" design pattern for a general mouse interaction. Here the simplified problem. I have a small 3d program (QT and openGL) and I use the mouse for interaction. Every interaction is normally not only a single function call, it is mostly performed by up to 3 function calls (initiate, perform, finalize). For example, camera rotation: here the initial function call will deliver the current first mouse position, whereas the performing function calls will update the camera etc. However, for only a couple of interactions, hardcoding these (inside MousePressEvent, MouseReleaseEvent MouseMoveEvent or MouseWheelEvent etc) is not a big deal, but if I think about a more advanced program (e.g 20 or more interactions) then a proper design is needed. Therefore, how would you design such a interactions inside QT. I hope I made my problem clear enough, otherwise don't bother complain :-) Thanks

  • How to set variable before callback is called?

    - by user1995327
    I'm trying to design a webpage... I have a function that I call get all info needed for an idividuals home page. A snippet of the codes is: exports.getHomePageData = function(userId, cb) { var pageData = {}; pageData.userFullName = dbUtil.findNameByUserId(userId, function(err){ if (err) cb(err); }); pageData.classes = dbUtil.findUserClassesByUserId(userId, function(err){ if (err) cb(err); }); cb(pageData); } The problem I'm having is the cb(pageData) is being called before I even finish setting the elements. I've seen that people use the async library to solve this but I was wondering if there was any other way for me to do it without needing more modules... Thanks!

  • Multiple asserts in single test?

    - by Gern Blandston
    Let's say I want to write a function that validates an email address with a regex. I write a little test to check my function and write the actual function. Make it pass. However, I can come up with a bunch of different ways to test the same function ([email protected]; [email protected]; test.test.com, etc). Do I put all the incantations that I need to check in the same, single test with several ASSERTS or do I write a new test for every single thing I can think of? Thanks!

  • Ajax Request not working. onSuccess and onFailure not triggering

    - by Kye
    Hi all, trying to make a page which will recursively call a function until a limit has been reached and then to stop. It uses an ajax query to call an external script (which just echo's "done" for now) howver with neither onSuccess or onFailure triggering i'm finding it hard to find the problem. Here is the javascript for it. In the header for the webpage there is a script to an ajax.js document which contains the request data. I know the ajax.js works as I've used it on another website var Rooms = "1"; var Items = "0"; var ccode = "9999/1"; var x = 0; function echo(string,start){ var ajaxDisplay = document.getElementById('ajaxDiv'); if(start) {ajaxDisplay.innerHTML = string;} else {ajaxDisplay.innerHTML = ajaxDisplay.innerHTML + string;} } function locations() { echo("Uploading location "+x+" of " + Rooms,true); Ajax.Request("Perform/location.php", { method:'get', parameters: {ccode: ccode, x: x}, onSuccess: function(reply) {alert("worked"); if(x<Rooms) { x++; locations(); } else { x=0; echo("Done",true); } }, onFailure: function() {alert("not worked"); echo("not done"); } }); alert("boo"); } Any help or advice will be most appreciated.

  • Bind jQuery UI autocomplete using .live()

    - by seth.vargo
    I've searched everywhere, but I can't seem to find any help... I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option. As an example, to bind all items with a class of .foo now and future created: $('.foo').live('click', function(){ alert('clicked'); }); It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete... This doesn't work: $('.foo').live('autocomplete', function(event, ui){ source: 'url.php' // (surpressed other arguments) }); How can I use .live() to bind autocomplete? UPDATE Figured it out with Framer: $(function(){ $('.search').live('keyup.autocomplete', function(){ $(this).autocomplete({ source : 'url.php' }); }); });

  • How can I create a generic constructor? (ie. BaseClass.FromXml(<param>)

    - by SofaKng
    I'm not sure how to describe this but I'm trying to create a base class that contains a shared (factory) function called FromXml. I want this function to instantiate an object of the proper type and then fill it via an XmlDocument. For example, let's say I have something like this: Public Class XmlObject Public Shared Function FromXml(ByVal source as XmlDocument) As XmlObject // <need code to create SPECIFIC TYPE of object and return it End Function End Class Public Class CustomObject Inherits XmlObject End Class I'd like to be able to do something like this: Dim myObject As CustomObject = CustomObject.FromXml(source) Is this possible?

  • Improve this snippet from a prototype class

    - by seengee
    This is a snippet from a prototype class i am putting together. The scoping workaround feels a little hacky to me, can it be improved or done differently? var myClass = Class.create({ initialize: function() { $('formid').getElements().each(function(el){ $(el).observe("blur", function(){ this.validateEl(el); }.bind(this,el)); },this); }, validateEl: function(el){ // validate $(el) in here... } }); Also, it seems to me that i could be doing something like this for the event observers: $('formid').getElements().invoke("observe","blur" ... Not sure how i would pass the element references in though?

  • Javascript: variable scope & the evils of globals

    - by Nick
    I'm trying to be good, I really am, but I can't see how to do it :) Any advice on how to not use a global here would be greatly appreciated. Let's call the global G. Function A Builds G by AJAX Function B Uses G Function C Calls B Called by numerous event handlers attached to DOM elements (type 1) Function D Calls B Called by numerous event handlers attached to DOM elements (type 2) I can't see how I can get around using a global here. The DOM elements (types 1 & 2) are created in other functions (E&F) which are unconnected with A. I don't want to add G to each event handler (because it's large and there's lots of these event handlers), and doing so would require the same kind of solution as I'm seeking here (i.e., getting G to E&F). The global G, BTW, is an array that is necessary to build other elements as they, in turn, are built by AJAX. I'm not convinced that a singleton is real solution, either. Thanks.

  • Using a singleton database class in functions and multiple scripts(PHP) - best use methods

    - by dscher
    I have a singleton db connection which I get with: $dbConnect = myDatabase::getInstance(); which is easy enough. My question is what is the least rhetorical and legitimate way of using this connection in functions and classes? It seems silly to have to declare the variable global, pass it into every single function, and/or recreate this variable within every function. Is there another answer for this? Obviously I'm a noob and I can work my way around this problem 10 different ways, none of which is really attractive to me. It would be a lot easier if I could have that $dbConnect variable accessible in any function without needing to declare it global or pass it in. I do know I can add the variable to the $_SERVER array...is there something wrong with doing this? It seems somewhat inappropriate to me. Another quick question: Is it bad practice to do this: $result = myDatabase::getInstance()-query($query); from directly within a function?

  • After .load() Reset Textbox with User Entered Value using JavaScript and jQuery

    - by Aaron Salazar
    My function below calls a partial view after a user enters a filter-by string into the text box '#DocId'. When the user is done typing, the partial view is displayed with filtered data. Since my textbox needs to be in the partial view, when user is done entering a filter-by string and is shown the filtered data, the textbox is reset and the user entered data is lost. How can I set the value of the textbox back to the user entered string after the partial view is displayed? I'm pretty sure I need to use .val() but I can't seem to get this to work. $(function() { $('#DocId').live('keyup', function() { clearTimeout($.data(this, 'timer')); var val = $(this).val(); var wait = setTimeout(function() { $('#tableContent').load('/CurReport/TableResults', { filter: val }, 500) }, 500); $(this).data('timer', wait); }); }); Thank you, Aaron

  • MMGR Questions, code use and thread-saftey

    - by chadb
    1) Is MMGR thread safe? 2) I was hoping someone could help me understand some code. I am looking at something where a macro is used, but I don't understand the macro. I know it contains a function call and an if check, however, the function is a void function. How does wrapping "(m_setOwner (FILE,_LINE_,FUNCTION),false)" ever change return types? #define someMacro (m_setOwner(__FILE__,__LINE__,__FUNCTION__),false) ? NULL : new ... void m_setOwner(const char *file, const unsigned int line, const char *func); 3) What is the point of the reservoir? 4) On line 770 ("void *operator new(size_t reportedSize)" there is the line "// ANSI says: allocation requests of 0 bytes will still return a valid value" Who/what is ANSI in this context? Do they mean the standards? 5) This is more of C++ standards, but where does "reportedSize" come from for "void *operator new(size_t reportedSize)"? 6) Is this the code that is actually doing the allocation needed? "au-actualAddress = malloc(au-actualSize);"

  • MFC/CCriticalSection: Simple lock situation hangs

    - by raph.amiard
    I have to program a simple threaded program with MFC/C++ for a uni assignment. I have a simple scenario in wich i have a worked thread which executes a function along the lines of : UINT createSchedules(LPVOID param) { genProgThreadVal* v = (genProgThreadVal*) param; // v->searcherLock is of type CcriticalSection* while(1) { if(v->searcherLock->Lock()) { //do the stuff, access shared object , exit clause etc.. v->searcherLock->Unlock(); } } PostMessage(v->hwnd, WM_USER_THREAD_FINISHED , 0,0); delete v; return 0; } In my main UI class, i have a CListControl that i want to be able to access the shared object (of type std::List). Hence the locking stuff. So this CList has an handler function looking like this : void Ccreationprogramme::OnLvnItemchangedList5(NMHDR *pNMHDR, LRESULT *pResult) { LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR); if((pNMLV->uChanged & LVIF_STATE) && (pNMLV->uNewState & LVNI_SELECTED)) { searcherLock.Lock(); // do the stuff on shared object searcherLock.Unlock(); // do some more stuff } *pResult = 0; } The searcherLock in both function is the same object. The worker thread function is passed a pointer to the CCriticalSection object, which is a member of my dialog class. Everything works but, as soon as i do click on my list, and so triggers the handler function, the whole program hangs indefinitely.I tried using a Cmutex. I tried using a CSingleLock wrapping over the critical section object, and none of this has worked. What am i missing ?

  • Need some help synch'ing outer loop counter with dialog.onconfirm()

    - by Chris Barnhill
    I am writing a game for Facebook. IN the following code, I have a problem. I have a for loop executing, and in that loop, I call a dialog and implement 'onconfirm' for the dialog. The problem is that I need to access th e loop counter inside of the onconfirm function. But because the onconfirm is called outside of the scope of the for loop, the counter value is no longer valid because it's been incremented. I need some way to pass the counter value to the dialog onconfirm as it was at the time the dialog was displayed, not after the loop has finished. Or maybe someone has a better solution. Any help would be appreciated. Thanks. function unloadCargo() { //debugger; var actionPrompt = document.getElementById('action-prompt'); actionPrompt.setTextValue('Unloading cargo...'); var ajax = new Ajax(); ajax.responseType = Ajax.JSON; ajax.ondone = function(data) { debugger; if(data.unloadableCargo.length == 0) { loadCargo(); } else { //console.log('unloadable cargo='+dump(data.unloadableCargo)); var i = 0; var j = 0; var ucCount = data.unloadableCargo.length; for(i = 0; i < ucCount; i++) { cargoDialog = new Dialog(); cargoDialog.showChoice('Unload Cargo', 'Unload ' + data.unloadableCargo[i].goods_name + ' at ' + data.unloadableCargo[i].city_name + ' for ' + data.unloadableCargo[i].payoff + 'M euros?'); cargoDialog.onconfirm = function() { //console.log('unloadable cargo onconfirm='+dump(data.unloadableCargo)); var ajax = new Ajax(); var param = {"city_id": data.unloadableCargo[i].city_id, "goods_id": data.unloadableCargo[i].goods_id, "payoff": data.unloadableCargo[i].payoff}; ajax.ondone = function(demandData) { var demands = document.getElementById('demands'); var innerXhtml = '<span>'; for(var j = 0; j < demandData.demands.length; j++) { innerXhtml = innerXhtml + ' <div class="demand-item"><div class="demand-city">' + demandData.demands[j].city + '</div><div class="demand-pay">' + demandData.demands[j].cost + '</div><div class="demand-goods">' + demandData.demands[j].goods + '</div></div>'; } innerXtml = innerXhtml + ' </span>'; demands.setInnerXHTML(innerXhtml); // update balance loadCargo(); } ajax.post(baseURL + "/turn/do-unload-cargo", param); } cargoDialog.oncancel = function() { loadCargo(); } } //loadCargo(); } } ajax.post(baseURL + '/turn/unload-cargo'); }

  • What are the rules governing how a bind variable can be used in Postgres and where is this defined?

    - by Craig Miles
    I can have a table and function defined as: CREATE TABLE mytable ( mycol integer ); INSERT INTO mytable VALUES (1); CREATE OR REPLACE FUNCTION myfunction (l_myvar integer) RETURNS mytable AS $$ DECLARE l_myrow mytable; BEGIN SELECT * INTO l_myrow FROM mytable WHERE mycol = l_myvar; RETURN l_myrow; END; $$ LANGUAGE plpgsql; In this case l_myvar acts as a bind variable for the value passed when I call: SELECT * FROM myfunction(1); and returns the row where mycol = 1 If I redefine the function as: CREATE OR REPLACE FUNCTION myfunction (l_myvar integer) RETURNS mytable AS $$ DECLARE l_myrow mytable; BEGIN SELECT * INTO l_myrow FROM mytable WHERE mycol IN (l_myvar); RETURN l_myrow; END; $$ LANGUAGE plpgsql; SELECT * FROM myfunction(1); still returns the row where mycol = 1 However, if I now change the function definition to allow me to pass an integer array and try to this array in the IN clause, I get an error: CREATE OR REPLACE FUNCTION myfunction (l_myvar integer[]) RETURNS mytable AS $$ DECLARE l_myrow mytable; BEGIN SELECT * INTO l_myrow FROM mytable WHERE mycol IN (array_to_string(l_myvar, ',')); RETURN l_myrow; END; $$ LANGUAGE plpgsql; Analysis reveals that although: SELECT array_to_string(ARRAY[1, 2], ','); returns 1,2 as expected SELECT * FROM myfunction(ARRAY[1, 2]); returns the error operator does not exist: integer = text at the line: WHERE mycol IN (array_to_string(l_myvar, ',')); If I execute: SELECT * FROM mytable WHERE mycol IN (1,2); I get the expected result. Given that array_to_string(l_myvar, ',') evaluates to 1,2 as shown, why arent these statements equivalent. From the error message it is something to do with datatypes, but doesnt the IN(variable) construct appear to be behaving differently from the = variable construct? What are the rules here? I know that I could build a statement to EXECUTE, treating everything as a string, to achieve what I want to do, so I am not looking for that as a solution. I do want to understand though what is going on in this example. Is there a modification to this approach to make it work, the particular example being to pass in an array of values to build a dynamic IN clause without resorting to EXECUTE? Thanks in advance Craig

  • Global variables that can be used in multiple jQuery functions

    - by YouBook
    Can you be able to contain variables that can be used in multiple functions in jQuery, example: var self = $(this); var box = self.parents('.box'); $('#title').click(function() { self.css('background', 'red'); box.slideDown('slow'); }).dblclick(function() { self.css('background', 'green'); box.slideUp('slow'); }); So that self and box can be used within these event functions so I don't have to keep doing this: $('#title').click(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'red'); }).dblclick(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'green'); }); But question is, is it possible, if so, how can you do that?

  • Problem with JQuery swapImage();

    - by VUELA
    Hello!~ On my articles page (http://www.adrtimes.squarespace.com/articles) I have each entry start with an image that changes on rollover. This is working fine. However, on my homepage (http://www.adrtimes.squarespace.com), I am loading in the 2 most recent articles that are not categorized as video, and the 2 most recent articles that are tagged as video. I am using jQuery load() to pull in the content from the articles page. Everything works ok with that except the swapImage rollovers on the homepage. i tried including the swapImage function as callbacks but only one group or the other will rollover properly, not both groups of content. I'm not sure what the problem is!! Here is the code: <script type="text/javascript"> <!-- $(function(){ $.swapImage(".swapImage"); /* Homepage */ // load recent articles $("#LoadRecentArticles").load("/articles/ .list-journal-entry-wrapper .journal-entry-wrapper:not(.category-video)", function(){ //callback... $("#LoadRecentArticles .journal-entry-wrapper").wrapAll('<div class="list-journal-entry-wrapper" />'); $("#LoadRecentArticles .journal-entry-wrapper:gt(1)").remove(); // modify Read More tag $('.journal-read-more-tag a:contains(Click to read more ...)').each(function(){ var str = $(this).html(); $(this).html(str.replace('Click to read more ...','Continue reading—')); }); $.swapImage(".swapImage"); }); // load recent videos $("#LoadRecentVideos").load("/articles/category/video .list-journal-entry-wrapper", function(){ //callback... $("#LoadRecentVideos .journal-entry-wrapper:gt(1)").remove(); $('<div class="VideoTag">—video</div>').insertBefore("#LoadRecentVideos .category-video .body img"); // modify Read More tag $('.journal-read-more-tag a:contains(Click to read more ...)').each(function(){ var str = $(this).html(); $(this).html(str.replace('Click to read more ...','Continue reading—')); }); $.swapImage(".swapImage"); }); }); --> </script> And here is a sample of the html for the images in an article entry: <a href="/articles/2010/5/6/article-title-goes-here.html"><img class="swapImage {src: '/storage/post-images/Sample2_color.jpg'}" src="/storage/post-images/Sample2_bw.jpg" /></a>

  • casting BSTR as char* in a dll; different results depnding on VB/C# caller.

    - by Toby Wilson
    I have a dll function that takes BSTR parameters. These are casted as char* before being used for other things. When the dll is called from VB code this works fine. However, when it is called from C# code, only the first character is pointed to. Both of these are excel addIns for Pre-2007 and 2007+ versions of Office, which call into a faster C++ AddIn. They actually call it directly, not through Excel. The VB function declaration looks like this: Private Declare Function Test Lib "ExcelAddIn.xll" (ByVal param As String) As String The C# function declaration looks like this: [DllImport("ExcelAddIn.xll", CharSet=CharSet.Ansi)] [return:MarshalAs(UnmanagedType.BStr)] private static extern string Test([MarshalAs(UnmanagedType.BStr)] string param); When debugging the dll and watching the input BSTR values, they appear to be correct from both; just the C# one only casts the first character. Charset=CharSet.Unicode makes no difference. Any ideas anyone?

  • How do you use indent in vim for web development?

    - by Somebody still uses you MS-DOS
    I'm starting to use Linux and Vim at work. I'm starting to read vims documentation and creating my own .vimrc file and such. I'm a web developer working with HTML, XML, CSS, JS, Python, PHP, ZPT, DTML and SQL. I would like to have an indent feature like this one: for each language/set, a corresponding indent solution. So, in js, writing function test(){|} would turn in function test(){ | } If php, writing <?php function test(){|}: <?php function test(){ | } <?php> ...and such. Writing a function definition in Python, and then creating a for loop sentece, it would automatically create an indent. I'm starting with autoindent, smartindent, cindent but I'm a little confused about their differences. How do the indent in vim works? Am I supposed to download plugins for each language? Is the behavior I described possible with already existing plugins you're used to or do I have to create it? I keep seeing people using Vim and I'm trying to do this as well since the machine I'm using is too limited, but I'm afraid I won't be able to have a decent auto indenting solution in it. (I have used autoindenting in a little small project in Visual Studio, and really liked their approach. Is there a plugin for that?)
