hook

问题 How can I call a hook for only a few controllers instead of all controllers in CodeIgniter? E.g.: I want to run the hook for only the admin section. How can I achieve this? 回答1: In the hook which you wish to run selectively, you can access the ci superobject using $this->ci =& get_instance(); . This acts as a pointer which can be used to access the CodeIgniter router to determine the class using $class = $this->ci->router->fetch_class(); . You can then check if $class matches a certain value.

问题 I need to change on the fly the value set on every node using the innerHTML. The closest solution I found is: ... Object.defineProperty(Element.prototype, 'innerHTML', { set: function () { // get value (ok) var value = arguments[0]; // change it (ok) var new_value = my_function(value); // set it (problem) this.innerHTML = new_value; // LOOP } } ... But obviously it's an infinite loop. Is there a way to call the original innerHTML set? I also try the Proxy way but i could not make it work.

问题 I need to create a query log in my project. So I created a post_controller hook. It saves all the executed queries in both a text file and a database. But it works only for SELECT queries. I know it is repeated question, but after a lot of search, I couldn't find solution. Here is my code: config/hooks.php: $hook['post_controller'] = array( 'class' => 'LogQueryHook', 'function' => 'log_queries', 'filename' => 'log_queries.php', 'filepath' => 'hooks' ); hooks/log_queries.php class LogQueryHook

问题 Suppose I have the following .NET classes: public class C { public void M() { .... } } and public class D { public void N() { .... } } These 2 classes reside in different namespaces, in different assemblies. Is there a way to cause all call to C.M() to 'redirect' automatically to D.N() ? So, the calling method things its invoking C.M , but in reality, D.N is what actually gets called, with any parameters that C.M would have taken. It doesn't matter if this happens for all instantiations of

问题 I make program with spyware features for education, and I need to know in the program when file system is changing file, and what file is being changed. How can I do that in C++? 回答1: On Windows, look at SHChangeNotifyRegister(). Not only does it tell you what kind of change occured, but it also tells you which exact file(s) were changed. 回答2: You are probably looking for Win32 Directory Change Notifications. There is also a .NET API called the FileSystemWatcher that exposes the same

问题 I'm building an application which needs to filter some mouse clicks system-wide. That is, I need to make the system ignore some mouse button clicks at special occasions. I use low level mouse hook and SetWindowsHookEx to filter out these clicks. It works relatively well, except for WPF applications. I guess that's because these applications use DirectX and DirectInput for input processing, and that's why I can't filter out clicks in these applications, since they get the input directly from

问题 I am trying to enforce a policy where each push gets rejected when even one of the commit messages does not satisfy a rule. I've distributed a hook to the devs in order for them to use it in their local repos but I also want to enforce this when they push to the origin. I have two questions: Should I use the update hook or the pre-receive hook? (I've tried to setup an update.secondary hook but it seems to me it doesn't get fired, while a pre-receive does). How can I get the message for each

问题 I would like to map: CAPS-LOCK to Fn Fn to Left-MOUSE LSHIFT + 3 to # RSHIFT + 3 to something else etc. I have searched exhaustively for any tool that offers complete freedom for remapping keyboard input, but cannot find one. (Windows has AutoHotkey). I'm planning to write my own tool that parses a config file. But how to actually dig in and do this? Solving this problem will require a thorough understanding of the journey of a keystroke through the operating system, so as to intercept at the
