  • Navbar Dropdown in Bootstrap 3

    - by user2333842
    I recently started learning and using Bootstrap 3. I figured I would start with something simple- a header and a dropdown bar. I used the code from the Bootstrap website. I started out with the basic Bootstrap template, then added the bootstrap navbar. This is my code so far. <!DOCTYPE html> <html> <head> <title>WEBSITE NAME</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <!-- Bootstrap --> <link href="css/bootstrap.min.css" rel="stylesheet" media="screen"> <!-- HTML5 shim and Respond.js IE8 support of HTML5 elements and media queries --> <!--[if lt IE 9]> <script src="../../assets/js/html5shiv.js"></script> <script src="../../assets/js/respond.min.js"></script> <![endif]--> </head> <body> <h1>WEBSITE NAME</h1> <nav class="navbar navbar-default" role="navigation"> <!-- Brand and toggle get grouped for better mobile display --> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> </div> <!-- Collect the nav links, forms, and other content for toggling --> <div class="collapse navbar-collapse navbar-ex1-collapse"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Tutorials</a></li> <li><a href="#">Software</a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li><a href="#">Separated link</a></li> <li><a href="#">One more separated link</a></li> </ul> </li> </ul> <form class="navbar-form navbar-left" role="search"> <div class="form-group"> <input type="text" class="form-control" placeholder="Search"> </div> <button type="submit" class="btn btn-default">Submit</button> </form> <ul class="nav navbar-nav navbar-right"> <li><a href="https://twitter.com/"><span class="glyphicon glyphicon-comment"></span> Twitter</a></li> <li><a href="https://youtube.com/"><span class="glyphicon glyphicon-facetime-video"></span> YouTube</a></li> </ul> </li> </ul> </div><!-- /.navbar-collapse --> </nav> <!-- jQuery (necessary for Bootstrap's JavaScript plugins) --> <script src="//code.jquery.com/jquery.js"></script> <!-- Include all compiled plugins (below), or include individual files as needed --> <script src="js/bootstrap.min.js"></script> </body> </html> The dropdown menu is absolutely not working at all- hovering or clicking it. What do I need to do?

  • ActiveRecord has_many and polymorphic

    - by leomayleomay
    I've came into a problem while working with AR and polymorphic, here's the description, class Base < ActiveRecord::Base; end class Subscription < Base set_table_name :subscriptions has_many :posts, :as => :subscriptable end class Post < ActiveRecord::Base belongs_to :subscriptable, :polymorphic => true end in the console, >> s = Subscription.create(:name => 'test') >> s.posts.create(:name => 'foo', :body => 'bar') and it created a Post like: #<Post id: 1, name: "foo", body: "bar", subscriptable_type: "Base", subscriptable_id: 1, created_at: "2010-05-10 12:30:10", updated_at: "2010-05-10 12:30:10"> the subscriptable_type is Base but Subscription, anybody can give me a hand on this?

  • reorder list elements - jQuery?

    - by Alex
    Hello, I am experimenting with jQuery lately, and I was wondering if it's possible with js or pure jquery to reorder <li> elements. So if I have a silly list like the following: <ul> <li>Foo</li> <li>Bar</li> <li>Cheese</li> </ul> How would I move the list elements around? Like put the list element with Cheese before the list element with Foo or move Foo to after Bar. So is it possible? If so, how? Thanks!!

  • A few question about some advanced Autohotkey uses

    - by user47625
    Hello, I'm using this wonderfull piece of software for some time now, but just for few quite basic things. So I'm wondering if these things would be possible: to use different set of shortcuts for different applications - so one shortcut performs different actions in different places. to make some form of modes for application, where you could use some swtch (vim style) and this would change things the shortucat would do if it would be possible to place some caption that indicates which mode you are using - little improvement of previous item I tkank everyone for answer.

  • Simple ant build script that supports src/ and test/?

    - by M-x
    Currently I use an IDE for all my builds and unit tests. Now I have a need to use ant. I found a few simple ant build.xml scripts but they didn't support a separate Junit test/ dir. My projects are structured as follows: src/ com/foo/ com/bar/ test/ -- Mirror of src/, with all *Test.java files. com/foo/ com/bar/ lib/ -- All Java libs, including junit 4. How can a construct a small ant script that builds my src/ and test/ Java classes then runs all my JUnit tests?

  • iphone dev - loading table content asynchronously

    - by Brian
    My app has a navigation controller which push and pop a series of views. One of the tableViews loads .xml file from URL and it takes 4-5 seconds. If I click the back button on the navigation bar, it will only respond after the content of the table finish loading. Is there an easy way to load the content asynchronously so that the app will still respond to my gesture on the navigation bar? p.s. I search this on the Internet and people are talking about multithreading. I don't know a lot about threads so please be more specific. Thanks in advanced =)

  • How to format an email address line (with name) with PHP?

    - by nbr
    I'm trying to generate email messages. The recipient's email address and name are specified by a user. What is the correct way to do this with PHP: $to_header = "To: $name <$email>" # incorrect! I already use a decent method for validating the email addressess (let's not go to that now...), but how do I properly encode $name with eg. QP when needed? For example, if the recipient is called "Foo Bär", I should produce (eg.) something like: To: =?utf-8?Q?Foo_B=C3=A4r?= <[email protected]>

  • Best way to create Default.png image for iPhone app

    - by Alex
    Originally I though I'll just take a screenshot of my app on the iPhone then tweak it in Photoshop. The images should be 480 x 320 according to Apple doc, and the dimensions of my screenshot are 480 x 320. But, the screenshot contains notification area (where reception bars, battery life, etc. are displayed) So, if I chop that part off my image will be a bit shorter and not 480px high. What do I do? Submit a shorter image? Stretch it up so it's 480px but without the notification bar? Submit it with the notification bar in the image? How did you create your Default.png?

  • Secure C# Assemblies from unauthorized Callers

    - by Creepy Gnome
    Is there any way to secure your assembly down to the class/property & class/method level to prevent the using/calling of them from another assembly that isn't signed by our company? I would like to do this without any requirements on strong naming (like using StrongNameIdentityPermission) and stick with how an assembly is signed. I really do not want to resort to using the InternalsVisibleTo attribute as that is not maintainable in a ever changing software ecosystem. For example: Scenario One Foo.dll is signed by my company and Bar.dll is not signed at all. Foo has Class A Bar has Class B Class A has public method GetSomething() Class B tries to call Foo.A.GetSomething() and is rejected Rejected can be an exception or being ignored in someway Scenario Two Foo.dll is signed by my company and Moo.dll is also signed by my company. Foo has Class A Moo has Class C Class A has public method GetSomething() Class C tries to call Foo.A.GetSomething() and is not rejected

  • xslt and xpath: match preceding comments

    - by miasbeck
    given this xml: <root> <list> <!-- foo's comment --> <item name="foo" /> <item name="bar" /> <!-- another foo's comment --> <item name="another foo" /> </list> </root> I'd like to use a XPath to select all item-nodes that have a comment immediately preceding them, that is I like to select the "foo" and "another foo" items, but not the "bar" item. I already fiddled about the preceding-sibling axis and the comment() function but to no avail.

  • Oracle 10g multiple DELETE statements

    - by bmw0128
    I'm building a dml file that first deletes records that may be in the table, then inserts records. Example: DELETE from foo where field1='bar'; DELETE from foo where fields1='bazz'; INSERT ALL INTO foo(field1, field2) values ('bar', 'x') INTO foo(field1, field2) values ('bazz', 'y') SELECT * from DUAL; When I run the insert statement by itself, it runs fine. When I run the deletes, only the last delete runs. Also, it seems to be necessary to end the multiple insert with the select, is that so? If so, why is that necessary? In the past, when using MySQL, I could just list multiple delete and insert statements, all individually ending with a semicolon, and it would run fine.

  • Triggering jquery event function at page load

    - by lazysoundsystem
    Here's a little jQuery function that does what I want when a checkbox is clicked, but I have a basic gap in my knowledge: How to register this so that it deals with checkboxes that are already clicked when the page loads? $(document).ready(function() { $('fieldset input:checkbox').click(function() { if ($(this).attr('name') == 'foo') { // hide checkbox 'bar' } else { // show checkbox 'bar' } } }); If I use .trigger('click'), it clicks (or unclicks) all the boxes on page load. I can think of a few ways to do this that would involve repeating portions of the code, but I just know that jQuery already has an elegant answer for this...

  • How to write a program that mimics Fiddler by using tcpdump or from scratch?

    - by ????
    When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

  • javascript function object's inheritFrom method

    - by gawpertron
    I've come across this.inheritFrom that enables you to inherit from a super class. var superClass = function() { this.foo = 'foo'; this.bar = 'bar'; } var subClass = function() { this.inheritFrom = superClass; this.inheritFrom(); this.myFunction = function() { return this.foo; }; } I've looked in Mozilla and MSDN, but I can't seem to find it documented any where. As far as I can see it works in IE6 and Firefox 3. Any reason why it wouldn't be documented?

  • Tabular.vim : how to align on the first occurrence of 2 different delimiters placed at the beginning of Words?

    - by ThG
    I have installed the Tabular plugin, which works very well for me, as long as there are no complicated regexes involved… But I have this list : one @abc @rstuvw &foo three @defg &bar four @mn @opq &kludge &hack twelve @hijkl &baz &quux I wish to align it that way (on @… first, then on &…) : one @abc @rstuvw &foo three @defg &bar four @mn @opq &kludge &hack twelve @hijkl &baz &quux which means I have 3 problems at the same time : align on the first occurrence of 2 different delimiters (@ and &) which are not really delimiters but "special characters" at the beginning of Words This is far beyond my understanding of both regexes and Tabular.vim How should I proceed ?

  • Count number of messages per user

    - by Pr0no
    Consider the following tables: users messages ----------------- ----------------------- user_id messages msg_id user_id content ----------------- ----------------------- 1 0 1 1 foo 2 0 2 1 bar 3 0 3 1 foobar 4 3 baz 5 3 bar I want to count the number of messages per user and insert the outcome into users.messages, like this: users ----------------- user_id messages ----------------- 1 3 2 0 3 2 I could use PHP to perform this operation, pseudo: foreach ($user_id in users) { $count = select count(msg_id) from messages where user_id = $user_id update users set messages = $count } But this is probably very inefficient as compared to one query executed in MySQL directly: UPDATE users SET messages = ( SELECT COUNT(msg_id) FROM messages ) But I'm sure this is not a proper query. Therefore, any help would be appreciated :-)

  • Make text appear briefly in a JPanel

    - by Roo
    Hi, I am trying to make text appear briefly before it disappears. It would be along the lines of 1) Set color to black 2) wait x amount of seconds 3) set color to background color The method I call is repaint(), which then calls paintComponent(Graphics painter). repaint() is called only if I press the space-bar. I thought of trying repaint();Thread.sleep(1000);repaint(); (I do catch the Interrupt exception, just not shown), but it only calls paintComponent once per space-bar . Is there an easy way to do this or is this something that is a bit challenging?
