This is—at least at the moment—purely experimentation, but I'm curious: is there a way to attach methods (via prototyping) to collections of elements? I've tested the following code: <div>a</div> <div>b</div> <div>c</div> <script> NodeList.prototype._ = function(s) { for (x = 0; x < this.length; x++) { eval('this[x]' + '....
Say I have the following C# code: Action a = TestMethod; Action b = TestMethod; Action c = b; b += a; Tests indicates that b is not the same instance as c, so clearly the + operator seems to create a new instance of the delegate. Is this a correct assumption? Does it reuse the b-instance internally, or does it just copy the method/tar...
Given my code below, is there a way that the first WebTestingApp constructor can call the second before returning the new instance? I want to set some readonly fields in the constructor and, short of copy/pasting, I can't see how I can. I feel that the answer will have something to do with constructor chaining, but I can't figure out ho...
Hi all, Imagine I have the methods: public static void funcA() {...} public static void funcB() { byteBuffer.wrap(someByteArray, 0, someByteArra.length); } IN JAVA API: public static ByteBuffer wrap(byte[]array, int offset, int length) { try { return new HeapByteBuffer(array, offset, length); } catch (IllegalAr...

Hello, I have a file that I want to read and write to a binary file using records. In the beginning I have an empty file and I want to add new record, but when I use the seekp function, then the location is at (-1) is it ok? Because when I check, I see that it hasnt written anything to the file. See code: void Library::addBook(Book ne...
I have multiple functions the do different animations to different parts of the HTML. I would like to chain or queue these functions so they will run the animations sequentially and not at the same time. I am trying to automate multiple events in sequence to look like a user has been clicking on different buttons or links. I could pro...
I'm trying to get the principles of doing jQuery-style function chaining straight in my head. By this I mean: var e = f1('test').f2().f3(); I have gotten one example to work, while another doesn't. I'll post those below. I always want to learn the first principle fundamentals of how something works so that I can build on top of it. Up...
I have some functions written in C that I call from Haskell. These functions return IO (CInt). Sometimes I want to run all of the functions regardless of what any of them return, and this is easy. For sake of example code, this is the general idea of what's happening currently: Prelude> let f x = print x >> return x Prelude> mapM_ f ...
Imagine I have a table with more than 9 rows. If I do this : $('table tr:gt(3):lt(6)'), shall I receive 3 or 6 elements at the end, and why ? Are all selectors applied to the same primary selection, or are they successively applied on different selections ? ...
I'm trying to implement route chaining for an admin panel on a Zend Framework site that I am working on. I'm using the following configuration file in hopes that the "admin" route routes with "/admin" and that the "adminLogin" route routes with "/admin/login". <?xml version="1.0" encoding="UTF-8"?> <routes> <admin> <route>admi...

Given this following sample code which clones a table row, sets some properties and then appends it to a table: $("#FundTable").append( objButton.parents("tr").clone() .find(".RowTitle").text("Row " + nAddCount).end() .find(".FundManagerSelect").attr("id", "FundManager" + nAddCount) .c...
I've just recently asked the folloiwng question with regard to jQuery chaning: http://stackoverflow.com/questions/1286829/is-there-a-preferred-way-of-formatting-jquery-chains-to-make-them-more-readable A number of people replied with the suggestion that maybe I reduced the amount of chaining within the statement, and instead stored obj...
How do I make chained objects in PHP5 classes? Examples: $myclass->foo->bar->baz(); $this->foo->bar->baz(); Not: $myclass->foo()->bar()->baz(); See also:http://www.talkphp.com/advanced-php-programming/1163-php5-method-chaining.html Thanks. /Kristoffer :-) ...
Alright, I have a really basic QStandardItemModel, filled with some numbers. I managed to display it in a QTableView, it's ok. I created a new model ( subclass either of QAbstractItemModel or QAbstractProxyModel ), which is some kind of a layer of an existing model - it is needed to set the sourcemodel, and this new layer should do some ...
I am trying to perform a query on a query result, but I am getting an error: “The method or operation is not implemented”. Can I chain queries in this way? For example, I have a Northwind typed DataSet. I do: queryResult = From product In NorthWindDataSet.Products Where (product.UnitsOnOrder > CInt(txtUnitsOnOrde...
Given the following class: public class MyClass { private string _param; public MyClass () { _param = string.Empty; } public MyClass (string param) { _param = param; } } I am torn apart between two ways to chain those constructors: The first one: public MyClass () : this (string.Empty) {...
Can I chain these two querysets into one? qs1 = OrderTicket.objects.filter(date__gt=datetime.date(2009, 1, 1), date__lt=datetime.date(2009, 1, 30)).values('order_type').annotate(value_1 = Sum('gbp_value')).order_by('order_type'), qs2 = OrderTicket.objects.filter(date__gt=datetime.date(2009, 2, 1), date__lt=datetime.date(2009, 2, 30)).va...
If I run this code, var waitRow = $(this).parent().parent().next().get(0); $(waitRow).children('td:nth-child(2)').html('some text').toggle(); toggle is not called. If I instead write the following code it works. Why? var waitRow = $(this).parent().parent().next().get(0); $(waitRow).children('td:nth-child(2)').html('some text'); $(wa...
