  • MS Office Excel Ribbon - Cannot change/hide Editing group in Home tab

    - by A9S6
    I have a .net addin for Excel. The addin creates the Ribbon UI for Excel 2007 and re-purposes some existing commands such as Cut, Copy, Paste, Sort etc. For Cut, Copy and Paste I am just overriding their OnAction value to call my own procedure when the buttons are clicked. But for Sort, Sort Asc and Sort Desc commands the case is a little different. When either of the Sort, Sort Asc or Sort Desc buttons are clicked, I want to get notified and then call the default functionality. This was possible in Excel 2003 commandsbars by calling the Execute() method on the CommandBarControl. In Excel 2007, there is a ExecuteMso() method to programmatically click a ribbon element but when the OnAction is overridden, this ExecuteMso() method just executes my own procedure and not the default functionality of that button. So I thought that I will HIDE the Sort buttons in the "Editing" group in Home tab and add my own Sort, Sort Asc and Sort Desc buttons to it. The buttons will call into my procedure first from where I will call the default behavior. Now the problem is that I am unable to change/hide the Editing group (idMso="GroupEditing"). Is this built-in group not editable? I can however HIDE the Clipboard and other groups(but can't add buttons to them). <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui"> <ribbon> <tabs> <tab idMso="TabHome"> <group idMso="GroupEditing" visible="false" /> </tab> </tabs> </ribbon> </customUI>

  • targeting sprites from a method in the document class - null object reference

    - by Freddyk
    Hi I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched. Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'. //This code works because it can access 'e.target'. private function photo1SpriteFlickHandler(e:GestureEvent):void { var openTween:Tween = new Tween(e.target, "x", Strong.easeOut, 232, 970, 5, true); } //this code gives me a null object reference because I am using 'photo1Sprite' rather than 'e.target' private function photo1SpriteFlickHandler(e:GestureEvent):void { var openTween:Tween = new Tween(photo1Sprite, "x", Strong.easeOut, 232, 970, 5, true); } //photo1Sprite has already been programatically added to the screen as so: var photo1Sprite = new TouchSprite(); var photo1Loader=new Loader(); photo1Loader.load(new URLRequest("media/photos1/photo1.jpg")); photo1Loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loaderComplete); photo1Sprite.x = 232; photo1Sprite.y = 538; photo1Sprite.scaleX = .3; photo1Sprite.scaleY = .3; photo1Sprite.blobContainerEnabled = true; photo1Sprite.addEventListener(TouchEvent.TOUCH_DOWN, startDrag_Press); photo1Sprite.addEventListener(TouchEvent.TOUCH_UP, stopDrag_Release); photo1Sprite.addChild(photo1Loader); addChild(photo1Sprite); So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.

  • Bug with DataBinding in WPF Host in Winforms?

    - by Tigraine
    Hi Guys, I've spent far too much time with this and can't find the mistake. Maybe I'm missing something very obvious or I may have just found a bug in the WPF Element Host for Winforms. I am binding a ListView to a ObeservableList that lives on my ProductListViewModel. I'm trying to implement searching for the ListView with the general Idea to just change the ObservableList with a new list that is filtered. Anyway, the ListView Binding code looks like this: <ListView ItemsSource="{Binding Path=Products}" SelectedItem="{Binding Path=SelectedItem}" SelectionMode="Single"> <ListView.ItemContainerStyle> <Style TargetType="{x:Type ListViewItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"></Setter> </Style> </ListView.ItemContainerStyle> <ListView.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Name}"></TextBlock> </DataTemplate> </ListView.ItemTemplate> </ListView> And the ViewModel code is as vanilla as it can get: private ObservableCollection<ProductViewModel> products; public ObservableCollection<ProductViewModel> Products { get { return products; } private set { if (products != value) { products = value; OnPropertyChanged("Products"); } } } Now the problem here: Once I debug into my OnPropertyChanged method, I can see that there are no subscribers to the PropertyChanged event (it's null), so nothing happens on the UI.. I already tried Mode=TwoWay and other Binding modes, it seems I can't get the ListView to subscribe to the ItemsSource... Can anyone help me with this? I'm just about to forget about the ElemenHost and just do it in Winforms greetings Daniel

  • trying to append a list, but something breaks

    - by romunov
    I'm trying to create an empty list which will have as many elements as there are num.of.walkers. I then try to append, to each created element, a new sub-list (length of new sub-list corresponds to a value in a. When I fiddle around in R everything goes smooth: list.of.dist[[1]] <- vector("list", a[1]) list.of.dist[[2]] <- vector("list", a[2]) list.of.dist[[3]] <- vector("list", a[3]) list.of.dist[[4]] <- vector("list", a[4]) I then try to write a function. Here is my feeble attempt that results in an error. Can someone chip in what am I doing wrong? countNumberOfWalks <- function(walk.df) { list.of.walkers <- sort(unique(walk.df$label)) num.of.walkers <- length(unique(walk.df$label)) #Pre-allocate objects for further manipulation list.of.dist <- vector("list", num.of.walkers) a <- c() # Count the number of walks per walker. for (i in list.of.walkers) { a[i] <- nrow(walk.df[walk.df$label == i,]) } a <- as.vector(a) # Add a sublist (length = number of walks) for each walker. for (i in i:num.of.walkers) { list.of.dist[[i]] <- vector("list", a[i]) } return(list.of.dist) } > num.of.walks.per.walker <- countNumberOfWalks(walk.df) Error in vector("list", a[i]) : vector size cannot be NA

  • Entity Framework 5 Enum Naming

    - by Tyrel Van Niekerk
    I am using EF 5 with migrations and code first. It all works rather nicely, but there are some issues/questions I would like to resolve. Let's start with a simple example. Lets say I have a User table and a user type table. The user type table is an enum/lookup table in my app. So the user table has a UserTypeId column and a foreign key ref etc to UserType. In my poco, I have a property called UserType which has the enum type. To add the initial values to the UserType table (or add/change values later) and to create the table in the initial migrator etc. I need a UserType table poco to represent the actual table in the database and to use in the map files. I mapped the UserType property in the User poco to UserTypeId in the UserType poco. So now I have a poco for code first/migrations/context mapping etc and I have an enum. Can't have the same name for both, so do I have a poco called UserType and something else for the enum or have the poco for UserType be UserTypeTable or something? More importantly however, am I missing some key element in how code first works? I tried the example above, ran Add-Migration and it does not add the lookup table for the enum.

  • Dynamic script addition should be ordered?

    - by hawkettc
    Hi, I'm adding some <script> tags dynamically to the head element after page load. I understand the scripts are loaded asynchronously, but can I expect them to be parsed in the order they are added? I'm seeing the expected behaviour in Firefox, but not in Safari or Chrome. Looking at the document in Chrome developer tools and Firebug, both show the following - <html> <head> ... <script type="text/javascript" src="A.js"></script> <script type="text/javascript" src="B.js"></script> </head> ... </html> However looking at the resource loading view, chrome seems to parse whichever is returned first from the server, while firebug always loads them in the order the script tags were added, even when B is returned first from the server. Should I expect Chrome/Safari to parse the files in the specified order? Using Chrome 5.0.375.29 beta on OS X 10.6.3

  • How to improve multi-threaded access to Cache (custom implementation)

    - by Andy
    I have a custom Cache implementation, which allows to cache TCacheable<TKey> descendants using LRU (Least Recently Used) cache replacement algorithm. Every time an element is accessed, it is bubbled up to the top of the LRU queue using the following synchronized function: // a single instance is created to handle all TCacheable<T> elements public class Cache() { private object syncQueue = new object(); private void topQueue(TCacheable<T> el) { lock (syncQueue) if (newest != el) { if (el.elder != null) el.elder.newer = el.newer; if (el.newer != null) el.newer.elder = el.elder; if (oldest == el) oldest = el.newer; if (oldest == null) oldest = el; if (newest != null) newest.newer = el; el.newer = null; el.elder = newest; newest = el; } } } The bottleneck in this function is the lock() operator, which limits cache access to just one thread at a time. Question: Is it possible to get rid of lock(syncQueue) in this function while still preserving the queue integrity?

  • JQuery: how to store records id for data from ajax query in dynamicly created html elements

    - by grapkulec
    Probably question title is rather cryptic but I will try to explain myself here so please bare with me :) Let's assume this configuration: server-side is PHP application responding for requests with data (list of items, single item details, etc.) in json format client-side is JQuery application sending ajax request to that PHP app and creating html content corresponding with received data So, for example: client requests "list of all animals with names staring with 'A'", gets the json response from server, and for every "animal" creates some html gizmo like div with animal description or something like that. It doesn't really matter what html element it will be but it has to point exactly to specific record by "containing" id of that record. And here is my dilemma: is it good solution to use "id" property for that? So it would be like: <div id="10" class="animal"> <p> This is animal of very mysterious kind... </p> </div> <div id="11" class="animal"> <p> And this one is very common to our country... </p> </div> where id="10" is of course indication that this is representation of record with id = 10. Or maybe I should store this record id in some custom made tag like <record_id>10</record_id> and leave an "id" strictly for what it was meant to be (css selector)? I need that record id for further stuff like updating database with some user input or deleting some of "animals" or creating new ones or anything that will be needed. All manipulations will be done with JQuery and ajax requests and responses will be visualized also with dynamic creation of html interface. I'm sure that somebody had to deal with that kind of stuff before so I would be grateful for some tips on that topic.

  • Javascript problem with iframe that's hidden before loaded

    - by Aistina
    I have a page that contains an iframe that gets loaded using Javascript: index.html <iframe id="myFrame" width="800" height="600" style="display: none;"></iframe> <div id="loader"><!-- some loading indicator --></div> <script type="text/javascript"> function someFunction() { var myFrame = document.getElementById('myFrame'); var loader = document.getElementById('loader'); loader.style.display = 'block'; myFrame.src = 'myFrame.html'; myFrame.onload = function() { myFrame.style.display = 'block'; loader.style.display = 'none'; }; } </script> The page that gets loaded in the iframe contains some Javascript logic which calculates the sizes of certain elements for the purposes of adding a JS driven scrollbar (jScrollPane + jQuery Dimensions). myFrame.html <div id="scrollingElement" style="overflow: auto;"> <div id="several"></div> <div id="child"></div> <div id="elements"></div> </div> <script type="text/javascript"> $(document).load(function() { $('#scrollingElement').jScrollPane(); }); </script> This works in Chrome (and probably other Webkit browsers), but fails in Firefox and IE because at the time jScrollPane gets called, all the elements are still invisble and jQuery Dimensions is unable to determine any element's dimensions. Is there a way to make sure my iframe is visible before $(document).ready(...) gets called? Other than using setTimeout to delay jScrollPane, which is something I definitely want to avoid.

  • Zend Framework/PHPUnit: How to Stub/Mock an object method that connects to a database?

    - by Andrew
    In my Zend Framework project, I have a form that I am testing. In my form, a multi-select element gets its options from a model, which gets the data from the database. public function init() { $this->addElement('select', 'Region_ID', array('multiOptions' => $this->getRegions())); } protected function getRegions() { $mapper = new Model_RegionMapper(); return $mapper->getFormSelectData(); //this method will try to connect to a database (or get another object that will connect to the database) } I tried copying the example in the PHPUnit documentation, but it doesn't seem to be working. public function setUp() { $stub = $this->getMock('Model_RegionMapper'); $stub->expects($this->any()) ->method('getFormSelectData') ->will($this->returnValue(array('testdata'))); } public function testFoo() { //this will fail $form = new My_Form(); } The test fails because it is trying to find a table in the database that doesn't exist. But I don't want it to connect to the database at all. How do I correctly stub/mock this method so that it doesn't call the database?

  • How to add files to a document library in a site definition in SharePoint 2007?

    - by jaloplo
    Hi all, I'm doing a site definition for SharePoint 2007. When the site is created, a document library called "Folder2" is created also. Now, I need to add some documents to this document library and appear as items in the document library standard views. My code is: <Lists> <List FeatureId="00bfea71-e717-4e80-aa17-d0c71b360101" Type="101" Title="Folder2" Url="Folder2"> <Data> <Rows> <Row> <Field Name="Name">MyFile.txt</Field> <Field Name="Title">MyFile.txt</Field> <Field Name="FileLeafRef">MyFile.txt</Field> </Row> </Rows> </Data> </List> </Lists> When I see the items of the Document Library there is one element with title "1_". Does anybody know how to add files in a site definition? The onet.xml I used is the same as blank site. Thanks!!!

  • javascript split() array contains

    - by Mahesha999
    While learning JavaScript, I did not get why the output when we print the array returned of the Sting.split() method (with regular expression as an argument) is as explained below. var colorString = "red,blue,green,yellow"; var colors = colorString.split(/[^\,]+/); document.write(colors); //this print 7 times comma: ,,,,,,, However when I print individual element of the array colors, it prints an empty string, three commas and an empty string: document.write(colors[0]); //empty string document.write(colors[1]); //, document.write(colors[2]); //, document.write(colors[3]); //, document.write(colors[4]); //empty string document.write(colors[5]); //undefined document.write(colors[6]); //undefined Then, why printing the array directly gives seven commas. Though I think its correct to have three commas in the second output, I did not get why there is a starting (at index 0) and ending empty string (at index 4). Please explain I am screwed up here.

  • char[] and char* compatibility?

    - by Aerovistae
    In essence, will this code work? And before you say "Run it and see!", I just realized my cygwin didn't come with gcc and it's currently 40 minutes away from completing reinstallation. That being said: char* words[1000]; for(int i = 0; i<1000; i++) words[i] = NULL; char buffer[ 1024 ]; //omit code that places "ADD splash\0" into the buffer if(strncmp (buffer, "ADD ", 4){ char* temp = buffer + 4; printf("Adding: %s", temp); int i = 0; while(words[i] != NULL) i++; words[i] = temp; } I'm mostly uncertain about the line char* temp = buffer + 4, and also whether I can assign words[i] in the manner that I am. Am I going to get type errors when I eventually try to compile this in 40 minutes? Also-- if this works, why don't I need to use malloc() on each element of words[]? Why can I say words[i] = temp, instead of needing to allocate memory for words[i] the length of temp?

  • WCF data services (OData), query with inheritance limitation?

    - by Mathieu Hétu
    Project: WCF Data service using internally EF4 CTP5 Code-First approach. I configured entities with inheritance (TPH). See previous question on this topic: Previous question about multiple entities- same table The mapping works well, and unit test over EF4 confirms that queries runs smoothly. My entities looks like this: ContactBase (abstract) Customer (inherits from ContactBase), this entity has also several Navigation properties toward other entities Resource (inherits from ContactBase) I have configured a discriminator, so both Customer and Resource map to the same table. Again, everythings works fine on the Ef4 point of view (unit tests all greens!) However, when exposing this DBContext over WCF Data services, I get: - CustomerBases sets exposed (Customers and Resources sets seems hidden, is it by design?) - When I query over Odata on Customers, I get this error: Navigation Properties are not supported on derived entity types. Entity Set 'ContactBases' has a instance of type 'CodeFirstNamespace.Customer', which is an derived entity type and has navigation properties. Please remove all the navigation properties from type 'CodeFirstNamespace.Customer'. Stacktrace: at System.Data.Services.Serializers.SyndicationSerializer.WriteObjectProperties(IExpandedResult expanded, Object customObject, ResourceType resourceType, Uri absoluteUri, String relativeUri, SyndicationItem item, DictionaryContent content, EpmSourcePathSegment currentSourceRoot) at System.Data.Services.Serializers.SyndicationSerializer.WriteEntryElement(IExpandedResult expanded, Object element, ResourceType expectedType, Uri absoluteUri, String relativeUri, SyndicationItem target) at System.Data.Services.Serializers.SyndicationSerializer.<DeferredFeedItems>d__b.MoveNext() at System.ServiceModel.Syndication.Atom10FeedFormatter.WriteItems(XmlWriter writer, IEnumerable`1 items, Uri feedBaseUri) at System.ServiceModel.Syndication.Atom10FeedFormatter.WriteFeedTo(XmlWriter writer, SyndicationFeed feed, Boolean isSourceFeed) at System.ServiceModel.Syndication.Atom10FeedFormatter.WriteFeed(XmlWriter writer) at System.ServiceModel.Syndication.Atom10FeedFormatter.WriteTo(XmlWriter writer) at System.Data.Services.Serializers.SyndicationSerializer.WriteTopLevelElements(IExpandedResult expanded, IEnumerator elements, Boolean hasMoved) at System.Data.Services.Serializers.Serializer.WriteRequest(IEnumerator queryResults, Boolean hasMoved) at System.Data.Services.ResponseBodyWriter.Write(Stream stream) Seems like a limitation of WCF Data services... is it? Not much documentation can be found on the web about WCF Data services (OData) and inheritance specifications. How can I overpass this exception? I need these navigation properties on derived entities, and inheritance seems the only way to provide mapping of 2 entites on the same table with Ef4 CTP5... Any thoughts?

  • How do I keep users from spoofing data through a form?

    - by Jonathan
    I have a site which has been running for some time now that uses a great deal of user input to build the site. Naturally there are dozens of forms on the site. When building the site, I often used hidden form fields to pass data back to the server so that I know which record to update. an example might be: <input type="hidden" name="id" value="132" /> <input type="text" name="total_price" value="15.02" /> When the form is submitted, these values get passed to the server and I update the records based on the data passed (i.e. the price of record 132 would get changed to 15.02). I recently found out that you can change the attributes and values via something as simple as firebug. So...I open firebug and change the id value to "155" and the price value to "0.00" and then submit the form. Viola! I view product number 155 on the site and it now says that it's $0.00. This concerns me. How can I know which record to update without either a query string (easily modified) or a hidden input element passing the id to the server? And if there's no better way (I've seen literally thousands of websites that pass the data this way), then how would I make it so that if a user changes these values, the data on the server side is not executed (or something similar to solve the issue)? I've thought about encrypting the id and then decrypting it on the other side, but that still doesn't protect me from someone changing it and just happening to get something that matches another id in the database. I've also thought about cookies, but I've heard that those can be manipulated as well. Any ideas? This seems like a HUGE security risk to me.

  • XML Schema: Can I make some of an attribute's values be required but still allow other values?

    - by scrotty
    (Note: I cannot change structure of the XML I receive, I am only able to change how I validate it.) Let's say I can get XML like this: <Address Field="Street" Value="123 Main"/> <Address Field="StreetPartTwo" Value="Unit B"/> <Address Field="State" Value="CO"/> <Address Field="Zip" Value="80020"/> <Address Field="SomeOtherCrazyValue" Value="Foo"/> I need to create an XSD schema that validates that "Street", "State" and "Zip" must be present. But I don't care if "StreetPartTwo" or "SomeOTherCrazyValue" is present. If I knew that only the three I care about could be included, I could do this: <xs:element name="Address" type="addressType" maxOccurs="unbounded" minOccurs="3"/> <xs:complexType name="addressType"> <xs:attribute name="Field" use="required"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="Street"/> <xs:enumeration value="State"/> <xs:enumeration value="Zip"/> </xs:restriction> </xs:simpleType> </xs:attribute> </xs:complexType> But this won't work with my case because I may also receive those other Address elements (that also have "Field" attributes) that I don't care about. Any ideas how I can ensure the stuff I care about is present but let the other stuff in too? TIA! Sean

  • Sorting XML file through multiple attributes

    - by jbugeja
    I want to sort a 'free-form' XML file through multiple attributes (first by T and then by L). The XML is a bit complex and it is structured as shown below: <?xml version="1.0" encoding="utf-8"?> <wb xmlns:cf="http://www.macromedia.com/2004/cfform" xmlns:a="urn:dummy"> <a:form name="chart"> <a:fieldset FIELD="a" FIELDNAME="FieldSet1"> <a:select1 FIELDNUMBER="01" L="1" T="2" /> <a:input FIELDNUMBER="02" INDEX="4" L="200" T="1" /> </a:fieldset> <a:fieldset FIELD="b" FIELDNAME="FieldSet1"> <a:select1 FIELDNUMBER="03" T="3" L="1" /> <a:input FIELDNUMBER="04" INDEX="7" T="4" L="200" /> <a:fieldset FIELD="c" FIELDNAME="FieldSet1"> <a:input FIELDNUMBER="05" T="10" INDEX="6" L="400" /> <a:input FIELDNUMBER="06" T="8" INDEX="8" L="200" /> </a:fieldset> </a:fieldset> <a:input FIELDNUMBER="08" INDEX="3" L="3" T="5" /> <a:input FIELDNUMBER="09" INDEX="2" L="2" T="4" /> </a:form> </wb> PS: The root element is wb and this is always followed by a:form The L and T are always found in elements that have a tag in the namespace a, the only exception being a:fieldset which does not have L and T a:fieldset could have multiple children of the namespace a including another a:fieldset We can also assume that L denotes Left and T denotes Top. So, the idea of this is that when I view the transformed XML I can immediately note which elements precede what. What's your take on this?

  • jQuery or CSS - How do you make a link in a table row appear underlined even when the cursor is in a

    - by adam
    I have a table of 3-4 columns, the central one being task names that are also links(yet another todo app..groan). Im trying to make it so that whenever the mouse hovers over any part of the table row - not just the link itself - the link will appear underlined. Its a small detail but its been annoying me like hell and i refuse to let it get the better of me now. At first i tried jQuery with a (forgive the obvious syntax errors but this is the jist) $('#row_in_question').hover( function(){ $(this).find(...the link..).toggleClass("highlighted") }, function(){ $(this).find(...the link..).toggleClass("highlighted") } ); with this as a styling for the a element in general .highlighted { text-decoration: underlined; } and it did indeed toggle the highlighted class on that link - however css inheritance got in the way and no visual changes made. Since i previously styled that link to have no underline when not hovered it wouldnt change the style. So how do i go about this? I dont want the whole row to become clickable, I just want the text to become underlined.

  • Appending unique values only in a linked list in C

    - by LuckySlevin
    typedef struct child {int count; char word[100]; inner_list*next;} child; typedef struct parent { char data [100]; inner_list * head; int count; outer_list * next; } parent; void append(child **q,char num[100],int size) { child *temp,*r,*temp2,*temp3; parent *out=NULL; temp = *q; temp2 = *q; temp3 = *q; char *str; if(*q==NULL) { temp = (child *)malloc(sizeof(child)); strcpy(temp->word,num); temp->count =size; temp->next=NULL; *q=temp; } else { temp = *q; while(temp->next !=NULL) { temp=temp->next; } r = (child *)malloc(sizeof(child)); strcpy(r->word,num); r->count = size; r->next=NULL; temp->next=r; } } This is my append function which I use for adding an element to my child list. But my problem is it only should append unique values which are followed by a string. Which means : Inputs : aaa bbb aaa ccc aaa bbb ccc aaa Append should act : For aaa string there should be a list like bbb->ccc(Not bbb->ccc->bbb since bbb is already there if bbb is coming more than one time it should be increase count only.) For bbb string there should be list like aaa->ccc only For ccc string there should be list like aaa only I hope i could make myself clear. Is there any ideas? Please ask for further info.

  • Is a full html page needed when loading a page with jQuery mobile?

    - by Vincent Hiribarren
    I am currently looking at jQuery mobile and its system of loading web pages with XmlHttpRequest. Thanks to that it is possible to automatically perform transition animations between two pages, for instance. However, something is not clear to me. If I understand correctly, each new page of a jQuery mobile powered website is injected in the DOM of the initial web page. The documentation of jQuery mobile even tells that because of this mechanism, the <title> tag of new webpages are not taken into account. So, in a way, if my initial webpage A.html loads a page B.html, I would tend to think that the webpage B.html does not need to have a full HTML grammar with the <html>, <head> or <body> tags. My page B.html could directly begin with a <div> element. Am I right?Is a full html page needed when loading a HTML page with jQuery mobile?What are the pros and cons about having a webpage with a wrong/truncated HTML syntax (appart that this page should not be accessed directly but through the main page)?

  • jquery callback functions failing to finish execution

    - by calumbrodie
    I'm testing a jquery app i've written and have come across some unexpected behaviour $('button.clickme').live('click',function(){ //do x (takes 2 seconds) //do y (takes 4 seconds) //do z (takes 0.5 seconds) }) The event can be triggered by a number of buttons. What I'm finding is that when I click each button slowly (allowing 10 seconds between clicks) - my callback function executes correctly (actions x, y & z complete). However If I rapidly click buttons on my page it appears that the function sometimes only completes up to step x or y before terminating. My question: Is it the case that if this function is fired by a clicking second DOM element, while the first callback function is completing - will jQuery terminate the first callback and start over again? Do I have to write my callback function explicitly outside the event handler and then call it?? function doStuff() { //do x //do y //do z ( } $('button.clickme).live('click',doStuff()) If this is the case can someone explain why this is happening or give me a link to some advice on best practice on closures etc - I'd like to know the BEST way to write jQuery to improve performance etc. Thanks

  • Grails - Removing an item from a hasMany association List on data bind?

    - by ecrane
    Grails offers the ability to automatically create and bind domain objects to a hasMany List, as described in the grails user guide. So, for example, if my domain object "Author" has a List of many "Book" objects, I could create and bind these using the following markup (from the user guide): <g:textField name="books[0].title" value="the Stand" /> <g:textField name="books[1].title" value="the Shining" /> <g:textField name="books[2].title" value="Red Madder" /> In this case, if any of the books specified don't already exist, Grails will create them and set their titles appropriately. If there are already books in the specified indices, their titles will be updated and they will be saved. My question is: is there some easy way to tell Grails to remove one of those books from the 'books' association on data bind? The most obvious way to do this would be to omit the form element that corresponds to the domain instance you want to delete; unfortunately, this does not work, as per the user guide: Then Grails will automatically create a new instance for you at the defined position. If you "skipped" a few elements in the middle ... Then Grails will automatically create instances in between. I realize that a specific solution could be engineered as part of a command object, or as part of a particular controller- however, the need for this functionality appears repeatedly throughout my application, across multiple domain objects and for associations of many different types of objects. A general solution, therefore, would be ideal. Does anyone know if there is something like this included in Grails?

  • Chrome renders button links completely screwed up when placed inside a paragraph

    - by Ferdy
    I am fairly proficient in CSS but now I am running into a very strange rendering issue in Google Chrome 9. I am trying to create some fancy looking link buttons (basically heavily styled anchors). Here is some example markup: <a href="" class="button"> <figure class="sprite icon icon_back"></figure> Link button with icon</a> This markup may look a litte strange to you, there's a few things you should know: I am using HTML5's figure class to include an icon as part of the button. I have the proper reset CSS applied and Chrome can render this tag for sure. Instead of actually pointing to an image I am applying CSS classes to the figure element. Within the CSS I am using the spriting technique to show the correct portion of a single large sprite image. All of this is working fine in Firefox, and actually also in Chrome. The correct rendering can be seen in the following image: It renders like that in both Firefox and Chrome. Here comes the problem, if I place such a button within paragraph tags <p></p> this is what happens in Chrome only: Notice how the button is ripped apart? Only in Chrome and only when placed inside a paragraph. It gets even stranger: this only happens for the first button inside the paragraph, if I would place three buttons inside a paragraph, only the 1st one is screwed up. Your first question would probably be about the CSS. It is rather verbose so hereby a temporary link to the page in question: Edit: link to live page removed, was only temporary for problem inspection.

  • Div's visibility with javascript - problem

    - by sammville
    I am trying to use div's to display content on my page. This is controlled with an onchange element in a select menu. It works perfectly but the problem is I want one div to close when another one is opened. The div's open fine but it does not close the others. An example code is below. What am I doing wrong? JavaScript: if(document.getElementById('catgry').value == '01'){ document.getElementById('post04').style.visibility = "visible"; document.getElementById('post04').style.display = ""; document.getElementById('post07').style.visibility = "hidden"; document.getElementById('post07').style.display = "none"; }else if(document.getElementById('catgry').value == '02'){ document.getElementById('post02').style.visibility = "visible"; document.getElementById('post02').style.display = ""; document.getElementById('post04').style.visibility = "hidden"; document.getElementById('post04').style.display = "none"; document.getElementById('post07').style.visibility = "hidden"; document.getElementById('post07').style.display = "none"; } HTML: <div id="post04" style="visibility:hidden; display:none;"> <table class="posttb"><tr> <td width="30%">Author</td> <td><input type="text" name="author" size="30" class="postfd"></td> </tr> </table> </div>

  • regexp target last main li in list

    - by veilig
    I need to target the starting tag of the last top level LI in a list that may or may-not contain sublists in various positions - without using CSS or Javascript. Is there a simple/elegant regexp that can help with this? I'm no guru w/ them, but it appears the need for greedy/non-greedy selectors when I'm selecting all the middle text (.*) / (.+) changes as nested lists are added and moved around in the list - and this is throwing me off. $pattern = '/^(<ul>.*)<li>(.+<\/li><\/ul>)$/'; $replacement = '$1<li id="lastLi">$3'; Perhaps there is an easier approach?? converting to XML to target the LI and then convert back? ie: Single Element <ul> <li>TARGET</li> </ul> Multiple Elements <ul> <li>foo</li> <li>TARGET</li> </ul> Nested Lists before end <ul> <li> foo <ul> <li>bar</li> </ul> <li> <li>TARGET</li> </ul> Nested List at end <ul> <li>foo</li> <li> TARGET <ul> <li>bar</li> </ul> </li> </ul>
