The top part does work, however. <script type = "text/javascript" > $ ( function rlAl () { if ( $ ( "#xicon1" ). hasClass ( "active" )) { $ ( "#actionlist" ). load ( "alcurrent.php" ); } else if ( $ ( "#xicon2" ). hasClass ( "active" )) { alert ( "icon2" ); } else if ( $ ( "#xicon3" ). hasClass ( "active" )) { alert ( "icon3" ); } }); $ ( function () { setInterval ( rlAl , 5000 ); }); </script> 回答1: rlAl is undefined

Common-Lisp source file *.lisp can be compiled into binary file *.fasl which can be loaded faster than the source file. Q:Can the Scheme source code *.scm be compiled into some binary file that will be loaded faster than the source code? Thanks in advance, joe 回答1: Yes, if the Scheme implementation you're using has that feature.

For example, the following C# code will fail at runtime and it's obvious why. dynamic x = 1.0 ; int y = x ; But that makes the dynamic features of C# pretty limited when dealing with loosely typed data such as that produced by JSON payloads or CSV where subtle variations in the representation can

The environment basically looks like this: \begin { quicktikz } ... some stuff ... \end { quicktikz } or like this: \begin *{ quicktikz } ... some stuff ... \end { quicktikz } I want to write a function that toggles between the two, when called from within the environment. Since my Vim knowledge ain't all that, I'm coming up with a simple solution: Get cursor position with let save_cursor=getpos(".") Backward search for \begin{quicktikz} using: ?\\begin{quicktikz}\|\

But I would also like a route to "courses" that is not in that namespace: eg: BOTH localhost:3000/admin/courses AND localhost:3000/courses It's OK if this requires different controllers. My concern is that its not really DRY if i have both resources for the same route. namespace admin do resources :courses end and just resources :courses Is there a way to have one resource be shared between namespace and without namespace, or is the

Is it possible to streamline the figure generation by having multiple python scripts that work on different parts of the figure? For example, if I have the following functions: FunctionA: Draw a histogram of something FunctionB: Draw a box with a text in it FunctionC: Draw a plot of something C FunctionD: Draw a plot of something D How do I go about reusing the above functions in different scripts? If I wanted, for instance, to create a figure with a histogram with a plot of something C, I would

It works like the following: class A : def __iter__ ( self ): print ( "iter" ) for _ in range ( 5 ): yield "something" def __len__ ( self ): print ( "len" ) n = 0 for _ in self : n += 1 return n Now if we take e.g. the length of an instance it prints len and iter , as expected: >>> len ( A ()) len iter 5 But if we call list() it calls both __iter__ and __len__ : >>> list ( A ()) len iter iter [ 'something' , 'something' ,

Here's how you'd do it: $array['Something']['More']['id'] If you particularly wanted access multidimensional arrays with a single string, then you could build a function to do that:

It saves CPU and disk use. 回答1: Windows provides an API for File Change Notification called FindFirstChangeNotification http://msdn.microsoft.com/en-us/library/aa365261(VS.85).aspx It turns out that somebody already made a small ruby-bridge for this you might use for a starting point: http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/36807 回答2: There is rb

This approach worked as expected for small data sets. However, when I populated strings.xml with the full data set (close to 2000 entries), I find that
