(7) understand the module and injector in angular, that is, dependency injection and angularinjector. The benefits of dependency injection (DI) are no longer described in detail. Anyone who has used the spring framework knows the benefits. Angularjs, as a front-end js framework, also provides DI support, which is a feature not available in javascript/jquery. In angularjs, there are DI-related angular. module (), angular.

Use several pieces of code to clarify the concepts and associations of $ injector, $ rootScope, and $ scope in angularJS. $ Injector, $ rootScope, and $ scope are important in the angularJS framework. clarifying the relationship between them is very useful for us to learn and understand the angularJS framework in the future. 1,$ Injector is actually an IOC contai

$injector, $rootScope, and $scope are important things in the AngularJS framework, and it is useful for us to follow up on the AngularJS framework of learning and understanding.1.$injector is actually an IOC container that contains a lot of services (similar to beans in the spring framework), and other code can pass $injector. Get ("ServiceName") way, Get the ser

Angular. JS learning dependency injection $ injector details, angular. jsinjector Preface Before dependency injection (IoC), it is very simple and straightforward to create an Object in the program, that is, to create a new Object in the code, we create, maintain, modify, and delete objects on our own. That is to say, we control the entire lifecycle of objects until they are not referenced and recycled. It is true that this practice is understandable

Module (), angular. injector (), $ injector, and $ provide. A di container must have three elements: Servic

Read Catalogue Inferred injection Tagged injection Inline-Injection $injector Common methods Sample code There are also concepts of dependency injection in Angularjs, like dependency injection in spring, but different. There are some additional things you need to do to use construct injection or set value injection in spring, but it is convenient to just declare it where you need it, like a reference to a module

, polluting the global namespace, and passing the reference through the function can also be done in two ways: 1, Closure package delivery 2, the background to resolve the dependent objects, and through Function.prototype.call the reference In Angularjs, dependency injection is implemented through the latter, and the following sections will introduce the implementation of the IOC module. Get dependencies var Fn_args =/^function\s*[^\ (]*\ (\s* ([^\)]*) \)/m; var fn_arg_split =/,/; Get

This is a feature that Javascript/jquery does not have.The Angularjs is related to di with Angular.module (), angular.injector (), NBSP; $injector, $provide object can be Applicationcontext.getbean () implemented; a dependency declaration, which can be configured in a

Angularjs source code parsing: injector and angularjsinjector Introduction Injector is used for Automatic Parameter injection, for example function fn ($http, $scope, aService) {} Ng automatically transmits $ http, $ scope, and aService as parameters for execution at runtime. In fact, it is easy to understand that injector has done two things. Cache those serv

parameters. In JS, we can introduce the dependency Using global variable references Pass through function arguments where needed The disadvantage of using global variables is that it pollutes the global namespace, and the reference is passed through a function, and can be implemented in two ways: Closure delivery The background resolves the dependent objects and passes the arguments through the Function.prototype.call In Angularjs, dependency injection is

This article describes the structure and running mode required by the next basic MVVMLight framework. After MVVMLight is installed, we can see a simple framework layout, such as the previous article, which generates a ViewModel fo

An inferred injection This injection method requires that the parameter name be the same as the service name. If the code is compressed and so on, it can cause the injection to fail. App.controller ("MyCtrl1", Function ($scope, Hello1,hello2) { $scope. Hello = function () { Hello1.hello (); Hello2.hello (); } ); Tagged injection This injection way, you need to set a dependent array, the array is dependent on the service name, in the function parameters, you
