mixins

问题 Hi I would like to implement Jade templates in my AngularJS project, and have mixin in my template (reusable code). However the problem that I am facing is that we cannot use Mixin with arguments. Am I doing it correctly or is there any alternative for the same in AngularJS that I am missing? 回答1: You can create an js object from your model and pass it as strings to the mixin like the following: +avatarRow({name: '{{avatar.name}}', uuid: '{{avatar.uuid}}', verificationCode: '{{avatar

问题 On the TypeScript's Decorator reference page there is a code snipped that illustrates how to override the constructor with class decorator: function classDecorator<T extends {new(...args:any[]):{}}>(constructor:T) { return class extends constructor { newProperty = "new property"; hello = "override"; } } @classDecorator class Greeter { property = "property"; hello: string; constructor(m: string) { this.hello = m; } } console.log(new Greeter("world")); and in logs: class_1 { property: 'property

问题 I'm trying to work out on SCSS how I would go about something like this: I would like to have a margin anywhere between 1px and 1000px and have a class for it. For example .MarginTop-x X being where I can write any value. Obviously I couldn't write out .MarginTop-1 {margin-top:1px} .MarginTop-2 {margin-top:2px} .MarginTop-3 {margin-top:3px} .MarginTop-4 {margin-top:4px} etc... 回答1: Well you need a @for loop to do that . SCSS : $class-slug: ".MarginTop"; $stop-loop: 4; @for $i from 0 through

问题 I'm using an specific mixin trying to make my code more clear. So instead of using: <div class="col-lg-3 col-md-5 col-sm-6 col-xs-12"> I'm using: <div class="stackOverflowRocksIt"> and in my mixins.less: .stackOverflowRocksIt{ .make-lg-column(3); .make-md-column(4); .make-sm-column(6); .make-xs-column(12); } It works properly with XS and SM viewports, but not when I resize to MD or LG (then is taking the SM size). Is this the proper way to create columns for different viewports sizes? Any

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . Using Java 6, how can I implement a mixin? It is very easy and possible in Ruby. How can I get similar in Java? 回答1: You could use CGLIB for that. The class Mixin is able to generate a dynamic class from several interfaces / object delegates: static Mixin create(java.lang.Class[]

问题 Given a class A and a module B, mixin the instance methods of B so that it overrides the correspnding instance methods of A. module B def method1 "B\#method1" end def method2 "B\#method2" end end class A def method1 "A\#method1" end def method2 "A\#method2" end # include B does not override instance methods! # (module gets mixed into the superclass) end puts A.new.method1 # want it to print out "B#method1" puts A.new.method2 # want it to print out "B#method2" 回答1: You could remove each of B

问题 I created a module in lib directory and I can freely call the various methods it contains throughout my Rails app (after adding include ModuleName) with no problems. However when it comes to tests, they complain no such methods exist. I tried including the module into my test helper with no luck. Can anyone help. 4) Error: test_valid_signup_redirects_user_to_spreedly(UsersControllerTest): NoMethodError: undefined method `spreedly_signup_url' for SpreedlyTools:Module /test/functional/user

问题 If I create an Object A: let A = {}; And want to mix in methods from another Object B: let B = { foo() { alert("Boo!"); } }; Normally I would call: Object.assign(A, B); Then I change my function foo: Object.assign(B, { foo() { alert("Hooray!"); } }); After that I call foo: A.foo(); // Actual output: "Boo!" But I want that output to be "Hooray!". So far I found out, that Object.assign only copies methods in the target, but it doesn't link them. About inheritance and composition I found useful

问题 I tried creating mixing in a getter into a JS object via the spread operator syntax, however it always seems to return null . HTML: <body> <div id="wrapperA"></div> <div id="wrapperB"></div> </body> <script src='./test.js'></script> JS: "use strict"; const mixin = { get wrapper() { return document.getElementById(this.wrappername); } } const wrapperA = { wrappername: 'wrapperA', ...mixin } const wrapperB = { wrappername: 'wrapperB', ...mixin } console.log(wrapperA); console.log(wrapperB);
