问题 PROBLEM I have a function that takes in a nested array where the structure and nesting of the array is unknown at run-time. All that is known is some of the target fieldnames and desired values of some of the leafs. QUESTIONS 1) I am hoping to modify this unknown structure and still have the code be readable and easily understood by fellow programmers. What (if any) solution will allow me to do things like this in PHP? // Pseudo-code for things I would like to be able to do // this is kinda

问题 I use some custom ActionModes in my application. When an action mode is closed, I do some housekeeping, like closing related views, updating changes, etc.. I detect the action mode has been closed in OnDestroyActionMode. My problem is, when inside of some of my ActionModes, the user may trigger another system actionmode (The text copy/paste/select). In that case, onDestroyActionMode is called and I erroneously asume the user is done with the first actionmode, rather than implement a "stack"

问题 I am using Ruby 1.9.2 and the Ruby on Rails v3.2.2 gem. After my previous question on how to “nest” the inclusion of modules when using the Ruby on Rails ActiveSupport::Concern feature, I would like to understand where I should state methods added to a class by including "nested" modules in order to make these instance methods of that class. That is, I have the following: class MyClass < ActiveRecord::Base include MyModuleA end module MyModuleA extend ActiveSupport::Concern included do

问题 I'm trying to have 4 sub fields, billing code, channel, subject code and name, autopopulate certain values based on the answer of their parent field, Event Type. In other words, if the answer to event type is "A", dropdown fields will appear for each sub field based on "A". 回答1: Let's say the first select-element of the document has the values 'Plant', 'Animal' and 'Ghost' and the next select-element should change when the selected value of first ele changes, then this is how we do it: var
