  • jQuery height() width()

    - by JamesBrownIsDead
    I have an image on the page: <img id="foobar" src="emptySpace.gif" /> The image has an absolute position of left: 0 and top: 0 in a .css file. When I try this in JavaScript onmouseover, the height and width don't change. What am I missing? var image = jQuery("#foobar"); image.height(500).width(500); What gives?

    I installed LAMP on Ubuntu 10.04. Now whenever I try to access http://localhost/ I get this message: Forbidden You don't have permission to access / on this server. Apache/2.2.14 (Ubuntu) Server at localhost Port 80 I tried changing the permissions of the var/www/ folder by clicking ALT-f2, typing in "gksu nautilus" and right clicking the folder and changing the permissions but I still get a 403 forbidden error. Any idea what's going on?

  • How to merge jquery autocomplete and fcbkListSelection functionality?

    - by Ben
    Initial caveat: I am a newbie to jquery and javascript. I started using the autocomplete jquery plugin recently from bassistance.de. Yesterday, I found the fcbkListSelection plugin (http://www.emposha.com/javascript/fcbklistselection-like-facebook-friends-selector.html) and am using it to include a selector in my application. What I now want to do is to merge the 2 pieces of functionality since there are lots of items in my selector list. To be more specific, I want to put a "Filter by Name" text box above the facebook list selection object in my html. When the user types a few characters into the "Filter by Name" text box, I want the items in the Facebook list selector to only show the items that contain the typed characters -- kind of like what autocomplete does already, but rather than the results showing below the text input box, I want them to dynamically update the facebook list object. Is this possible and relatively straightforward? If so, can somebody please describe how to do it? If not, is there an easier way to approach this? Thanks! OK, to Spencer Ruport's comment, I guess I may have a more specific question already. Below is the current Javascript in my HTML file (angle brackets represent Django tags). #suggest1 and #fcbklist both do their separate pieces, but how do I get them to talk to each other? Do I need to further write javascript in my HTML file, or do I need to customize the guts of the plugins' .js? Does this help elaborate? $(document).ready(function() { var names = []; var count = 0; {% for a, b, c in friends_for_picker %} names[count] = "{{ b }}"; count = count+1; {% endfor %} function findValueCallback(event, data, formatted) { $("<li>").html( !data ? "No match!" : "Selected: " + formatted).appendTo("#result"); } function formatItem(row) { return row[0] + " (<strong>id: " + row[1] + "</strong>)"; } function formatResult(row) { return row[0].replace(/(<.+?>)/gi, ''); } $("#suggest1").autocomplete(names, { multiple: true, mustMatch: false, autoFill: true, matchContains: true, }); //id(ul id),width,height(element height),row(elements in row) $.fcbkListSelection("#fcbklist","575","50","4"); });

  • Change C# sorting behaviour

    - by Erik
    Lets say i have the strings abc_ and abc2_. Now, normally when sorting i C# abc2_ would come after abc_, leaving the result: abc_ abc2_ I am using this to sort, if it matters: var element = from c in elements orderby c.elementName ascending select c; How can i change this? I want abc_ to come last. Reversing is not an option because the list is contains more than two elements.

  • Data access pattern, combining push and pull?

    - by andlju
    I need some advice on what kind of pattern(s) I should use for pushing/pulling data into my application. I'm writing a rule-engine that needs to hold quite a large amount of data in-memory in order to be efficient enough. I have some rather conflicting requirements; It is not acceptable for the engine to always have to wait for a full pre-load of all data before it is functional. Only fetching and caching data on-demand will lead to the engine taking too long before it is running quickly enough. An external event can trigger the need for specific parts of the data to be reloaded. Basically, I think I need a combination of pushing and pulling data into the application. A simplified version of my current "pattern" looks like this (in psuedo-C# written in notepad): // This interface is implemented by all classes that needs the data interface IDataSubscriber { void RegisterData(Entity data); } // This interface is implemented by the data access class interface IDataProvider { void EnsureLoaded(Key dataKey); void RegisterSubscriber(IDataSubscriber subscriber); } class MyClassThatNeedsData : IDataSubscriber { IDataProvider _provider; MyClassThatNeedsData(IDataProvider provider) { _provider = provider; _provider.RegisterSubscriber(this); } public void RegisterData(Entity data) { // Save data for later StoreDataInCache(data); } void UseData(Key key) { // Make sure that the data has been stored in cache _provider.EnsureLoaded(key); Entity data = GetDataFromCache(key); } } class MyDataProvider : IDataProvider { List<IDataSubscriber> _subscribers; // Make sure that the data for key has been loaded to all subscribers public void EnsureLoaded(Key key) { if (HasKeyBeenMarkedAsLoaded(key)) return; PublishDataToSubscribers(key); MarkKeyAsLoaded(key); } // Force all subscribers to get a new version of the data for key public void ForceReload(Key key) { PublishDataToSubscribers(key); MarkKeyAsLoaded(key); } void PublishDataToSubscribers(Key key) { Entity data = FetchDataFromStore(key); foreach(var subscriber in _subscribers) { subscriber.RegisterData(data); } } } // This class will be spun off on startup and should make sure that all data is // preloaded as quickly as possible class MyPreloadingThread { IDataProvider _provider; MyPreloadingThread(IDataProvider provider) { _provider = provider; } void RunInBackground() { IEnumerable<Key> allKeys = GetAllKeys(); foreach(var key in allKeys) { _provider.EnsureLoaded(key); } } } I have a feeling though that this is not necessarily the best way of doing this.. Just the fact that explaining it seems to take two pages feels like an indication.. Any ideas? Any patterns out there I should have a look at?

  • Booking form works but does not give feedback

    - by Naim
    I have a form where people can book seats for a given event. It's actually a WordPress plugin. When someone sends his booking, email notifications are sent properly and the event booking status is updated accordingly. The issue is that the booking form does not give any feedback whatsoever. Once you hit "book now", the graphic keeps loading and no feedback is ever displayed like for instance "booking sent successfully" or "there are errors in your form", even though the booking is saved correctly with both sides notified by email. I guess it's a JavaScript issue,Firebug console is not showing any error... So here is the code source of the booking form : Also please experience the issue live Here username: tester password: testsa Thanks! $('#em-booking-form').submit( function(e){ e.preventDefault(); var em_booking_doing_ajax = false; $.ajax({ url: EM.bookingajaxurl, data:$('#em-booking-form').serializeArray(), dataType: 'jsonp', type:'post', beforeSend: function(formData, jqForm, options) { if(em_booking_doing_ajax){ alert(EM.bookingInProgress); return false; } em_booking_doing_ajax = true; $('.em-booking-message').remove(); $('#em-booking').append('<div id="em-loading"></div>'); }, success : function(response, statusText, xhr, $form) { $('#em-loading').remove(); $('.em-booking-message').remove(); $('.em-booking-message').remove(); //show error or success message if(response.result){ $('<div class="em-booking-message-success em-booking-message">'+response.message+'</div>').insertBefore('#em-booking-form'); $('#em-booking-form').hide(); $('.em-booking-login').hide(); $(document).trigger('em_booking_success', [response]); }else{ if( response.errors != null ){ if( $.isArray(response.errors) && response.errors.length > 0 ){ var error_msg; response.errors.each(function(i, el){ error_msg = error_msg + el; }); $('<div class="em-booking-message-error em-booking-message">'+error_msg.errors+'</div>').insertBefore('#em-booking-form'); }else{ $('<div class="em-booking-message-error em-booking-message">'+response.errors+'</div>').insertBefore('#em-booking-form'); } }else{ $('<div class="em-booking-message-error em-booking-message">'+response.message+'</div>').insertBefore('#em-booking-form'); } } $('html, body').animate({ scrollTop: $("#em-booking").first().offset().top - 50 }); //sends user back to top of form //run extra actions after showing the message here if( response.gateway != null ){ $(document).trigger('em_booking_gateway_add_'+response.gateway, [response]); } if( !response.result && typeof Recaptcha != 'undefined'){ Recaptcha.reload(); } }, complete : function(){ em_booking_doing_ajax = false; $('#em-loading').remove(); } }); return false; });

  • jquery ajax error cannot find url outside of debug mode

    - by John Orlandella Jr.
    I inherited some code two weeks ago that is using the jquery.ajax method to connect to a .NET web service. Here is the piece of code give me the trouble... if (MSCTour.AppSettings.OFFLINE !== 'TRUE') { $.ajax({ url: url, data: json, type: "POST", contentType: "application/json", timeout: 10000, dataType: "json", // not "json" we'll parse success: function(res){ if (!callback) { return; } /* // *** Use json library so we can fix up MS AJAX dates */ var result = ""; if (res !== "") { try { result = $.evalJSON(res); } catch (e) { result = {}; bare = true; } } /* // *** Bare message IS result */ if (bare) { callback(result); return; } /* // *** Wrapped message contains top level object node // *** strip it off */ for (var property in result) { callback(result[property]); break; } }, error: function(xhr,status,error){ if (status === 'parsererror') {} else {return error;} }, complete: function(res, status){ if (callback) { if ((status != 'success' && status != 'error') || status === 'parsererror' || (status === 'timeout' && res !== '')) { try { result = $.secureEvalJSON(res); } catch (e) { result = {}; bare = true; } callback(res); } } return; } }); } The url variable at this point equals /testsite/service.svc/GetItems Now here is where my problem lies... When running this site out of debug mode through visual studio I am not having any problem connecting to the database through the web service and seeing all my data, for both viewing and updating. When I go through the normal web server for the same site, on the same page, no data is showing up. When I put a break on the error portion of the code above in firebug this is information I am getting in the image linked below. link text I am getting what appears to be a 404 error, but when I look on the server all of the files are in the right place... coupled with the fact that it works when in debug mode, I think I am slowly going crazy staring at these same lines of code trying to find the needle in the haystack. Any help or just a direction to look in would be greatly appreciated.

  • Saving a reference to a int.

    - by Scott Chamberlain
    Here is a much simplified version of what I am trying to do static void Main(string[] args) { int test = 0; int test2 = 0; Test A = new Test(ref test); Test B = new Test(ref test); Test C = new Test(ref test2); A.write(); //Writes 1 should write 1 B.write(); //Writes 1 should write 2 C.write(); //Writes 1 should write 1 Console.ReadLine(); } class Test { int _a; public Test(ref int a) { _a = a; //I loose the reference here } public void write() { var b = System.Threading.Interlocked.Increment(ref _a); Console.WriteLine(b); } } In my real code I have a int that will be incremented by many threads however where the threads a called it will not be easy to pass it the parameter that points it at the int(In the real code this is happening inside a IEnumerator). So a requirement is the reference must be made in the constructor. Also not all threads will be pointing at the same single base int so I can not use a global static int either. I know I can just box the int inside a class and pass the class around but I wanted to know if that is the correct way of doing something like this? What I think could be the correct way: static void Main(string[] args) { Holder holder = new Holder(0); Holder holder2 = new Holder(0); Test A = new Test(holder); Test B = new Test(holder); Test C = new Test(holder2); A.write(); //Writes 1 should write 1 B.write(); //Writes 2 should write 2 C.write(); //Writes 1 should write 1 Console.ReadLine(); } class Holder { public Holder(int i) { num = i; } public int num; } class Test { Holder _holder; public Test(Holder holder) { _holder = holder; } public void write() { var b = System.Threading.Interlocked.Increment(ref _holder.num); Console.WriteLine(b); } } Is there a better way than this?

  • IE image map remains clickable behind another div

    - by Ryan Giglio
    I have an Image Map of the United States. When you click on a state, the map fades out and a map of that state appears with an image map of the area codes in the state. In Firefox, Safari, and Chrome, the state map becomes clickable and the United States map becomes unclickable until you close the sate popover. However in Internet Explorer, the United States map remains clickable through the state popover, and I cannot click on any area codes. Here is my javascript: $(document).ready(function() { $("#usMap").html(); $("#usMap").load("/includes/us_map.inc"); }); $('area').live('click', function() { var state = $(this).attr("class"); var statePopover = $("<div id='statePopoverContainer'><a id='popoverCloseButton'>Close State</a><div id='statePopover'></div></div>"); $("#usMap").append(statePopover); $("#usMapImage").fadeTo('slow', 0.2); $("#statePopover").load("/includes/stateMaps/" + state + ".html"); }); $("#popoverCloseButton").live('click', function() { $("#statePopoverContainer").remove(); $("#usMapImage").fadeTo('slow', 1); }); I am loading the map on document ready because if you don't have Javascript, something else appears. And here is the CSS for all things related: div#usMap { width:676px; height:419px; text-align: center; position: relative; background-color:#333333; z-index: 1; } img#usMapImage { z-index: 1; } area { cursor: pointer; } div#statePopoverContainer { width:100%; height:100%; z-index:5; position:absolute; top:0; left:0; } a#popoverCloseButton { position:absolute; right:0; padding-right:5px; padding-top:5px; color:#FFFFFF; cursor:pointer; } You can see this happening at http://dev.crewinyourcode.com/ Login with beta/tester

Click “Install and Run” to install the provisioning profile “distribution” on “myphone” and continue running “helloworld.app”. and it has a button "install and run" ive clicked on that hundreths of times and nothing. in orgranizer i see a tab called console ive cleared it and rebuild the app and there is some output that i dont understand.
