问题 So, using a HTML 5 compliant video player, (like Video JS) how would one go about loading a video dynamically, without having to reload the entire page? Imagine, a list of links (something like a playlist), and each link points to a video. When clicking the link, I want to load the selected video into player. Currently, I'm using an Iframe that holds the video player, so basically a I pass a variable on to the Iframe, and reload it. I don't think this is ideal, for a few reasons; it doesn't

问题 I need your help to write a script in Python that will take dynamically changed data, the source of data is not matter here, and display graph on the screen. I know how to use matplotlib, but the problem with matplotlib, that I can display graph only once, at the end of the script. I need to be able not only to display graph one time, but also update it on the fly, each time when data changes. I found that it is possible to use wxPython with matplotlib to do this, but it is little bit

问题 This is an offshoot question that's related to another I asked here. I'm splitting it off because it's really a sub-question: I'm having difficulties casting an object of type dynamic to another (known) static type. I have an ironPython script that is doing this: import clr clr.AddReference("System") from System import * def GetBclUri(): return Uri("http://google.com") note that it's simply newing up a BCL System.Uri type and returning it . So I know the static type of the returned object.

While it builds, and the sample executes correctly, the timings show that dynamic property access with HyperDescriptor is the slowest possible way of getting/setting object

问题 class C end var = "I am a local var outside" C.class_eval do def self.a_class_method puts var end end I know, this is not correct, because the def created a new scope. I also know that use define_method can create a instance method without creating a new scope, but my point is how to define a class method . 回答1: Class methods don't really exist in Ruby, they are just singleton methods of the class object. Singleton methods don't really exist, either, they are just ordinary instance methods of

问题 How to create dynamic nested menu from json object? I started using Angular Material Design today for the first time and I'm trying to create nested menus using material design. The documentation is pretty straight forward for static stuff. But I need to create dynamic nested menu from json object and I can't find a simple solution to this anywhere. It just needs to be one level deep. json object(not set in stone): my_menu = { 'main1': ['sub1', 'sub2'], 'main2': ['sub1', 'sub2'], } which
