  • jQuery - add additional parameters on submit (NOT ajax)

    - by Stacey
    Using jQuery's 'submit' - is there a way to pass additional parameters to a form? I am NOT looking to do this with Ajax - this is normal, refresh-typical form submission. $('#submit').click(function () { $('#event').submit(function () { data: { form['attendees'] = $('#attendance').sortable('toArray').toString(); }); });

  • How To Get YEARWEEK() To See Sunday As The Start Of The Week?

    - by tan
    I'm trying to get the YEARWEEK function to see Sunday as the 1st day of the week. An example date is: Sunday 1st Mar 2009 Here is my sql SELECT YEARWEEK('2009-03-01') and the result is - 200909 Which is week 9. I believe it is telling me this is week 9 because it sees the sunday as the last day of the previous week. How would I get this function to see sunday as the 1st day of the week and therefore return as week 10?

  • Restrict type of method parameter with two or more class names?

    - by Kirzilla
    Hello, We can restrict type of method parameters; for example, we should say that function parameter should be an instance of object described in class with name "Some Class". function some_function(Some_Class $object) { } Is there any php native posibilities to restrict method parameter with two or more classes? For examle, "Some Class" or "Some Class2" or "Some Class3". Or maybe there is any way to restrict method parameter with classes which implements interface with name "Some_Interface"? Thank you.

  • How to see if type is instance of a class in Haskell?

    - by Raekye
    I'm probably doing this completely wrong (the unhaskell way); I'm just learning so please let me know if there's a better way to approach this. Context: I'm writing a bunch of tree structures. I want to reuse my prettyprint function for binary trees. Not all trees can use the generic Node/Branch data type though; different trees need different extra data. So to reuse the prettyprint function I thought of creating a class different trees would be instances of: class GenericBinaryTree a where is_leaf :: a -> Bool left :: a -> a node :: a -> b right :: a -> a This way they only have to implement methods to retrieve the left, right, and current node value, and prettyprint doesn't need to know about the internal structure. Then I get down to here: prettyprint_helper :: GenericBinaryTree a => a -> [String] prettyprint_helper tree | is_leaf tree = [] | otherwise = ("{" ++ (show (node tree)) ++ "}") : (prettyprint_subtree (left tree) (right tree)) where prettyprint_subtree left right = ((pad "+- " "| ") (prettyprint_helper right)) ++ ((pad "`- " " ") (prettyprint_helper left)) pad first rest = zipWith (++) (first : repeat rest) And I get the Ambiguous type variable 'a0' in the constraint: (Show a0) arising from a use of 'show' error for (show (node tree)) Here's an example of the most basic tree data type and instance definition (my other trees have other fields but they're irrelevant to the generic prettyprint function) data Tree a = Branch (Tree a) a (Tree a) | Leaf instance GenericBinaryTree (Tree a) where is_leaf Leaf = True is_leaf _ = False left (Branch left node right) = left right (Branch left node right) = right node (Branch left node right) = node I could have defined node :: a -> [String] and deal with the stringification in each instance/type of tree, but this feels neater. In terms of prettyprint, I only need a string representation, but if I add other generic binary tree functions later I may want the actual values. So how can I write this to work whether the node value is an instance of Show or not? Or what other way should I be approaching this problem? In an object oriented language I could easily check whether a class implements something, or if an object has a method. I can't use something like prettyprint :: Show a => a -> String Because it's not the tree that needs to be showable, it's the value inside the tree (returned by function node) that needs to be showable. I also tried changing node to Show b => a -> b without luck (and a bunch of other type class/preconditions/whatever/I don't even know what I'm doing anymore).

  • Setting up an independent delegate?

    - by fuzzygoat
    Its common for the dataSource and delegate to be the same object, its also common for this object to be the viewController. In all the info/tutorials that I have seen online delegates are always setup as above. If I wanted to create my own class instead can anyone give me any pointers as to how I might do that. Where does that object get instantiated, how do you connect the dataSource and delegate items etc. I am using UITableView to test this.

  • What does @@variable mean in Ruby?

    - by Andrew
    What are Ruby variables preceded with double at signs (@@)? My understanding of a variable preceded with an at sign is that it is an instance variable, like this in PHP: PHP version class Person { public $name; public function setName($name) { $this->name = $name; } public function getName() { return $this->name; } } Ruby equivalent class Person def set_name(name) @name = name end def get_name() @name end end What does the double at sign @@ mean, and how does it differ from a single at sign?

  • Finding the type of an object in C++

    - by lemnisca
    I have a class A and another class that inherits from it, B. I am overriding a function that accepts an object of type A as a parameter, so I have to accept an A. However, I later call functions that only B has, so I want to return false and not proceed if the object passed is not of type B. What is the best way to find out which type the object passed to my function is?

    Hello everyone. How can I remove the . and .. from a path in Delphi (not using .NET). I need a function, so I can pass it something like 'c:\program files..\program files...', and I want the function to return to me 'c:\'. Can Delphi do that on its own? Or do I need to do it myself?

  • Timing issue with jQuery and $(document).ready()

    - by ripper234
    I have the following code block code when the document is ready: $(document).ready(function() { createDivs(); // creates some divs with class 'foo'; // iterate $(".foo").each(function(index) { alert(index + " - " + $(this).text()); }); } I find that the "iterate" part misses the divs I created in the createDivs() method entirely! Is there some timing issue I'm not aware of? Why doesn't jquery see the divs that were just created?
