namespaces

问题 What are some current "rules of thumb" for implementing JQuery namespaces to host general purpose utility functions? I have a number of JavaScript utility methods scattered in various files that I'd like to consolidate into one (or more) namespaces. What's the best way to do this? I'm currently looking at two different syntaxes, listed in order of preference: //****************************** // JQuery Namespace syntax #1 //****************************** if (typeof(MyNamespace) === "undefined"

问题 I'm currently working on a large web app built on backbone.js and have been having a lot of issues with organization, "zombies," etc. so I've decided to do a major refactor of code. I've already written a bunch of helper functions for dealing with the "zombies"; however, I'd like to start from the very beginning and create a nice structure/organization to the code. I haven't found many great tutorials/examples on large-scale backbone.js organization so I've sort of started from scratch and

问题 Consider a pair of two source files: an interface declaration file ( *.h or *.hpp ) and its implementation file ( *.cpp ). Let the *.h file be like the following: namespace MyNamespace { class MyClass { public: int foo(); }; } I have seen two different practices for using namespaces in source files: *.cpp showing practice #1: #include "MyClass.h" using namespace MyNamespace; int MyClass::foo() { ... } *.cpp showing practice #2: #include "MyClass.h" namespace MyNamespace { int MyClass::foo() {

问题 I am trying to convert a legacy app from JointJS v2.2.1 to v3.0.2. I’m hitting an error others have found: Uncaught Error: dia.ElementView: markup required. (joint.min.js:8) A helpful person said: “Please note you need to be careful with the cellViewNamespace for the dia.Paper and cellNamespace option for the dia.Graph in this setup. Running this snippet is a quick check you've set up the namespaces correctly: const cells = JSON.stringify(graph.toJSON()); graph.clear(); graph.fromJSON(JSON

问题 use level1\level2\level3; Can someone explain with a simple demo ? 回答1: To clear up any confusion regarding different syntax use, namespaces support only two syntaxes, either bracketed or simple-combination both will work. I suggest if you use one over the other, be consistent. <?php namespace my\stuff\nested { // <- bracketed syntax class foo {} } ?> It creates a class foo inside of the nested namespace with bracketed syntax ( {} ), it is equivalent to <?php namespace my\stuff { // bracketed

问题 I asked this question recently: create a namespace in c++/cli? and so I am trying to create my own namespace in c++/cli. But when I use the same namespace in two separate files (.cpp), the namespace is clearly not recognized as being the same because I get errors when I try to reference the other class in the other file. Here's basically what I have: Pets.cpp: namespace Animals { public ref class Pets { public: List<Dog> ^vDogs; Pets::Pets() { vDogs = gcnew List<Dog^>(); } void Pets:

问题 I need to parse an XML response from a web service using JQuery http://code.jquery.com/jquery-1.11.0.min.js Here you are a sample of my XML <?xml version='1.0' encoding="ISO-8859-1" ?> <wfs:FeatureCollection xmlns:ms="http://mapserver.gis.umn.edu/mapserver" xmlns:wfs="http://www.opengis.net/wfs" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas

问题 In principle, I could keep these extensions not-exported, and this would also allow me to not-add redundant documentation for these already well-documented methods, while still also passing R CMD check myPackage without any reported WARNING s. What are some of the drawbacks, if any? Is this possibly recommended to keep extensions of basic methods compartmentalized within the package that defines them? Alternatively, will this make it more difficult for another package to depend on mine, if

问题 Consider: A Swift framework called FrameworkA that defines the type Thing . A Swift framework called FrameworkB that also defines the type Thing and the type FrameworkA . An app that imports both frameworks in the same Swift file. How do I reference FrameworkA.Thing in said file? The following line fails with Thing is not a member of FrameworkA . let t : FrameworkA.Thing? = nil 回答1: This appears to be a Swift bug. As a workaround, you can create a new Swift file in the app that imports only

问题 On MSDN I can read what it does, but I would like to know what it does technically (tells compiler where to look for types..)? I mean using as a directive. 回答1: The primary function of the using directive is to make types within a namespace available without qualification to the user code. It considers the set of namespaces and types which are defined in referenced assemblies and the project being compiled. Take for example the following definition in MyTypes.Dll namespace MyTypes { class
