  • Dynamic menu items (change text on click)

    - by Mathijs Delva
    Hello, i need some help with a menu. See the following menu: menu The code for this menu: <div id="menu"> <ul> <li class="home"><a href="#home" class="panel">home / <span class="go">you are here</span></a></li> <li class="about"><a href="#about" class="panel">about / <span class="go">go here</span></a></li> <li class="cases"><a href="#cases" class="panel">cases / <span class="go">go there</span></a></li> <li class="photos"><a href="#photos" class="panel">photos / <span class="go">maybe here</span></a></li> <li class="contact"><a href="#contact" class="panel">contact / <span class="go">or even here<span></span></a></li> </ul> </div> What i want to do: onclick a menu item: 1. change the red text to yellow 'you are here' 2. change the previous menu item back to its original state (eg red and "go here"). The 4 values "go here", "go there", "maybe here", "or even here" are the 4 values that should be assigned to the other menu items (like the example). This is the code i already have: $('#menu ul li.home').addClass('active') $('#menu ul li.active a .go').html("you are here"); $("#menu ul li").click(function () { $('#menu ul li.active').removeClass('active'); $(this).addClass('active'); $('#menu ul li.active a .go').html("you are here"); }); var arr = [ "go here", "go there", "maybe here", "or even here" ]; var obj = { item1: "go here", item2: "go there" ,item3: "maybe here", item4: "or even here"}; $('#menu ul li').click(function () { var str = $('#menu ul li.active a .go').text(); $('#menu ul li.active a .go').html(str); }); As you see, it's incomplete. I don't how to get the values from the array and assign them too a menu item. The replace text works, but not the change-back-to-original-state. Also, right now, for some reason i can't click ONTO the list item itself in order to activate the jquery code. I need to click just a few pixels under it. But i guess that's a css issue. If anyone can help, i'd be super thankful! Regards, Mathijs

  • Add a custom class name to Wordpress body tag?

    - by Scott B
    I'd like to place a directive in my theme's functions.php file which appends a classname to the wordpress body tag. Is there a built-in API method for this? For example, my body tag code is... <body <?php if(function_exists("body_class") && !is_404()){body_class();} else echo 'class="page default"'?>> And it results in the following being written to the body tag (depending on the context in which the page is presented (page, post, logged-in, etc) <body class="home blog logged-in"> Depending on the child theme I'm using at the time, I want it to be... <body class="home blog logged-in mychildthemename">

  • Can't get a List(Of <my class>) from a Dictionary in .NET?

    - by magsto
    I have a Dictionary with key of type UInteger and the value is List(Of Session) where the (Public) class Session contains a couple of variables and a constructor (Public Sub New(...)). Some of the variables in my Session class is: Private count As Integer Private StartDate As Date Private Values As List(Of Integer) and a couple of methods like: Friend Sub Counter(ByVal c as Integer) count += c End Sub There is no problem to add values to the Dictionary: Dim Sessions As New List(Of Session) Dim dict As New Dictionary(Of Integer, Sessions) then some code to fill up a couple of Session objects in Sessions (not shown here) and then: dict.Add(17, Sessions) 'No problem Sessions.Clear() Sessions = dict(17) 'This doesn't return anything! The Sessions object is empty even if the code doesn't returned any error. Is my class Session to compex to be stored in a Dictionary?

  • c# class design - what can I use instead of "static abstract"?

    - by Ryan
    I want to do the following public abstract class MyAbstractClass { public static abstract int MagicId { get; } public static void DoSomeMagic() { // Need to get the MagicId value defined in the concrete implementation } } public class MyConcreteClass : MyAbstractClass { public static override int MagicId { get { return 123; } } } However I can't because you can't have static abstract members. I understand why I can't do this - any recommendations for a design that will achieve much the same result? (For clarity - what I am trying to do is provide a library with an abstract base class but the concrete versions MUST implement a few properties/methods themselves and yes, there are good reasons for keeping it static.)

  • Silently binding a variable instance to a class in C++?

    - by gct
    So I've got a plugin-based system I'm writing. Users can create a child class of a Plugin class and then it will be loaded at runtime and integrated with the rest of the system. When a Plugin is run from the system, it's run in the context of a group of plugins, which I call a Session. My problem is that inside the user plugins, two streaming classes called pf_ostream and pf_istream can be used to read/write data to the system. I'd like to bind the plugin instance's session variable to pf_ostream and pf_istream somehow so that when the user instantiates those classes, it's already bound to the session for them (basically I don't want them to see the session internals) I could just do this with a macro, wrapping a call to the constructor like: #define MAKE_OSTREAM = pf_ostream_int(this->session) But I thought there might be a better way. I looked at using a nested class inside Plugin wrapping pf_ostream but it appears nested classes don't get access to the enclosing classes variables in a closure sort of way. Does anyone know of a neat way to do this?

  • Weird "?>" being displayed

    - by Jaxkr
    I have the following navigation bar script: <?php session_start(); require('includepath.inc.php'); require($include_path.'loginsysfunc.inc.php'); $current_page = $_SERVER['REQUEST_URI']; ?> <div class="navbar"> <img class="navlogo" src="logo.png"> <div class="navbutton"><a href="index.php">Home</a></div> <div class="navbutton"><a href="about.php">About</a></div> <div class="navbutton"><a href="donate.php">Donate</a></div> <?php if (loggedIn()){ ?> <div class="navusername"><a href="profile.php?user=<?php echo $_SESSION['username'];?>"><?php echo $_SESSION['username']; ?></a></div> <div class="navtoolsettings"><a href="settings.php">Settings</a></div> <div class="navtoollogout"><a href="logout.php">Log out</a> <?php } elseif ($current_page == '/login.php') { ?> <div class="navregister"><a href="register.php">Register</a></div> <?php } else { ?> <div class="navusername"><a href="login.php">Log in</a></div> <?php } ?> </div> For some reason, a strange "?" is being displayed. I am super confused, so please help.

But, here it is: <?php $include_path = '/home/a6595899/public_html/include/'; ?> Here is loginsysfunc.inc.php. These are functions that go with my login system to save time: <?php function valUser() { session_regenerate_id(); $_SESSION['valid'] = true; $_SESSION['username'] = $userid; echo '<meta http-equiv="refresh" content="0;URL=\'index.php\'">'; } function loggedIn() { if($_SESSION['valid'] == true) { return true; } else { return false; } } function createSalt() { $string = $string = md5(uniqid(rand(), true)); return substr($string, 0, 3); } function logout() { $_SESSION = array(); session_destroy(); echo '<meta http-equiv="refresh" content="0;URL=\'index.php\'">'; } ?> Here is the actual HTML of the page: <!DOCTYPE html> <html> <head> <link href="style.css" rel="stylesheet" type="text/css"> <title> Log in </title> </head> <body> <div class="navbar"> <img class="navlogo" src="logo.png"> <div class="navbutton"><a href="index.php">Home</a></div> <div class="navbutton"><a href="about.php">About</a></div> <div class="navbutton"><a href="donate.php">Donate</a></div> <div class="navregister"><a href="register.php">Register</a></div> </div> ?> <div class="loginbox"> <h1>Log in</h1> <form action="logingo.php" method="POST"> <input class="userpass" type="text" name="username" value="Username" onFocus="this.value='';"> <br> <input class="userpass" type="password" name="password" value="Password" onFocus="this.value='';"> <br> <input class="loginbutton" type="submit" value="Log in!"> </form> </div> </body> </html>

  • How do I gather a class' css attributes given nothing but the className?

    - by user1128571
    For example I might have some css stuff that looks like this: .divType1 { position: absolute; width: 60px; height: 60px; left: 400px; top: 100px; border: 1px solid #89B; z-index: 0; } Now within Javascript I want to gather div class divType1' css attributes, but am provided only with the div class, so I can't do something of form ( pseudo-code ): selectDivWithClass( divType1 ).getCss(left). I could hack something by instantiating a div with class divType1 and grab its css attributes, and then destroy it, but is there a better way?

  • Access a static variable by $var::$reference

    - by chuckg
    I am trying to access a static variable within a class by using a variable class name. I'm aware that in order to access a function within the class, you use call_user_func(): class foo { function bar() { echo 'hi'; } } $class = "foo"; all_user_func(array($class, 'bar')); // prints hi However, this does not work when trying to access a static variable within the class: class foo { public static $bar = 'hi'; } $class = "foo"; call_user_func(array($class, 'bar')); // nothing echo $foo::$bar; // invalid How do I get at this variable? Is it even possible? I have a bad feeling this is only available in PHP 5.3 going forward and I'm running PHP 5.2.6. Thanks.

  • How to use composition from another class to set Name?

    - by user1874549
    I have some of the code here. I am trying to use one class to reference another so I may obtain the first name of the person. I want the firstName in main class to work but IDE mentions the variable isn't found. Will replacing 'first' with 'firstName' work? Main class: public BasePlusCommissionEmployee( String first, String last, String ssn, double sales, double rate, double salary) { cE = new CommissionEmployee( first, last, ssn, sales, rate ); setBaseSalary( salary ); } public void setFirstName(String firstName) { // Trying to get this to work... cE.setFirstName(first); } SubClass: private String firstName; public void setFirstName( String first ) { firstName = first; }

  • Are static members of a generic class tied to the specific instance?

    - by mafutrct
    This is more of a documentation than a real question. I noticed the principle it is not described on SO yet (did I miss it?), so here goes: Imagine a generic class that contains a static member: class Foo<T> { public static int member; } Is there a new instance of the member for each specific class, or is there only a single instance for all Foo-type classes? It can easily be verified by code like this: Foo<int>.member = 1; Foo<string>.member = 2; Console.WriteLine (Foo<int>.member); What is the result, and where is this behavior documented?

  • How does ruby allow a method and a Class with the same name?

    - by Daniel Beardsley
    I happened to be working on a Singleton class in ruby and just remembered the way it works in factory_girl. They worked it out so you can use both the long way Factory.create(...) and the short way Factory(...) I thought about it and was curious to see how they made the class Factory also behave like a method. They simply used Factory twice like so: def Factory (args) ... end class Factory ... end My Question is: How does ruby accomplish this? and Is there danger in using this seemingly quirky pattern?
