问题 So in Xamarin, one of the navigational methods of pulling up a new page is the PushModalAsync call, which brings a new page without any normal navigational pieces. But not having pieces like a back button also removes the ability to navigate backwards... So is there a way to UN-pushmodalasync per se? Call up a page and then put it back down, like with a button or something along those line? I know Push Async does that, but I'd like the full page without the navigation bar at the top. A page

问题 I created a composite component that receives a managed bean as a parameter. The composite has a submit h:commandButton that runs a method from the managed bean parameter ( #cc.attrs.mBean.action} ; signature: String action() ). Knowing about the use of the target attribute in composite:implementation if I were using a method-signature instead of a bean action: is there a way to achieve a similar behavior when using a bean method?

问题 I'm trying to make a stupid horizontal nav bar with a drop-down on some of the items. The way I decided to do it is just by putting the drop-down in a div tag. This is easily changeable, i just don't like to go heavy on the html side. Basically I just want my drop down to work when you hover over the parent element. Additional css is going to be used to make it pretty and positioned better. Here's my js: var dropdown = $('.dropdown'); var parent = dropdown.parent(); $(parent).hover( function

问题 I am building a responsive website using a modified 960 grid: @media only screen and (min-width: 720px) and (max-width: 959px){ .container_12{ margin-left: auto; margin-right: auto; width: 720px; } } and a navigation bar that uses position:fixed to lock itself to the top of the page. .nav-band{ width: 100%; font-weight: bold; position: fixed; z-index: 3; overflow: hidden; background-image:url('../img/trans_black.png'); padding: 2px; } This works fine in most cases, but it breaks on my android

问题 I'm writing an action method that will store a new object in a database. Once this is done, I want to navigate to view that newly created object. To do this, I was planning to include a querystring or some sort of parameter in the return String of the action method, but I can't figure out how. If I append a query string manually, it appears that it's being ignored. Also, manually adding parameters by concatenating strings doesn't seem like a good idea to me. Is it possible to do this in a

问题 Hi I have a quiz app that gives you a score in a UILabel after answering each question, so I have a button that when you hit the correct answer you get 10 points and if hit the wrong answer you get 0 points, but how do I bring the int score value to the next question, which is pushed by a navController. Also if anyone knows a way to just have the last view (ScoreView) of the quiz be updated every time you answer the question that would be better than updating the score on every view 回答1: You

问题 I am trying to edit my header.php to call the navigation label of a page as opposed to the page title . Here is the existing code... <title><?php wp_title( '' ); ?></title> What is the code for calling or echoing the navigation label of a menu item?
