AngularJS is making one frame SPA (single-page applications) and other dynamic Web applications most widely used. I think that programmers use AngularJS encoded with a big list of points should be remembered, it will be one way or another way to help you. Here are some best practices suggested I observe, but also want to recommend to you. I firmly believe that more features should also be part of this list, I invite you all to make recommendations or comments below, Nike Air Max making this into a complete best practice guidelines. First, the dependency injection: 1. Dependency injection is one of the best features AngularJS framework, we should use it regularly. When we need to test our application coverage, it will really help to play. 2. dependent aliases, so they will not (JS code) compression process renamed because the AngularJS dependence is achieved by naming (Note: AngularJS by the controller constructor parameter names to infer dependency service name ʱ?? angular.module ('myApp') controller ('MyController', ['$ scope', 'MyService', function ($ scope, MyService) {// Nike Free Run 3 controller logic}]);. Second, the scope 1. In the templates ( template) and scope (scope) by a read-only treatment. This means that even if AngularJS allows us to write code templates to modify the scope, we must be very careful or should not do. 2. controllers (controller) in scope only by written treated. That is a controllers responsible for the use of another component, like a service, access template data to be displayed and the data is written in an object Air Max 2012 Black Navy Blue White scope. As a rule of thumb, we must always use. '' When binding. This means that we should be bound to the scope of the object, rather than directly attribute, it may cause unexpected behavior in the sub $ scope, $ scope since the prototype based inheritance mechanism of Java-script. The following code, we can see, superhero is the scope of an object returned by Superhero service, while the same object is used to bind the view (view). \u0026 Lt; div class = \u0026 quot; form-group \u0026 quot; \u0026 gt; \u0026 lt; label class = \u0026 quot; control-label \u0026 quot; for = \u0026 quot; name \u0026 quot; \u0026 gt; Super Power \u0026 lt; / label \u0026 gt; \u0026 lt; div class = \u0026 quot; controls \u0026 quot; \u0026 gt; \u0026 lt ; input type = \u0026 quot; text \u0026 quot; data-ng-model = \u0026 quot; superhero.superPower \u0026 quot; \u0026 gt; \u0026 lt; / div \u0026 gt; $ scope superhero = Superheros.get ({superheroId: $ stateParams.superheroId)};. Scope The purpose is to reference model, instead of becoming model. JavaScript Object Model is our three Authentication Nike Free Run 3 Women 1. Use 'novalidate' property in the form (form) tags to use AngularJS verify while closing the HTML5 validation. \u0026 Lt; form name = \u0026 quot; reviewForm \u0026 quot; ng-controller = \u0026 quot; ReviewController as reviewCtrl \u0026 quot; ng-submit = \u0026 quot; reviewCtrl.addReview (product) \u0026 quot; novalidate \u0026 gt;. 2 we can use angular classes (css class) to change visibility and verification of the control state. .ng-valid.ng-dirty {border-color: Nike Lebron 10(X) # FA787E;} ng-invalid.ng-dirty {border-color: # FA787E;} Four, memory - task management AngularJS in the destruction of a scope and put a scope from. It broadcasts a $ destroy event before removing its parent. Listen to this event to 579756 403 Purple White Nike Black Mamba 24 Kobe Sale clean up tasks and resources are critical, or may continue to consume memory or CPU. Always registered 'destroy' event to remove any code easier to memory leaks. As an example, the following controller in one second intervals and constantly updating a mode (model) l value, these updates will last forever, even if the corresponding view controller disappears or is removed from the parent scope. If a user navigates to a view back and forth to load the controller, each navigation will add another timer run forever. module.controller (\u0026 quot; MyController \u0026 quot ;, function ($ scope, $ timeout) {var onMyTimeout = function () {$ scope.value + = 1; $ timeout (onMyTimeout, 100);}; $ timeout (onMyTimeout, 100) ; $ scope.value = 0;}); listens $ destroy event is an opportunity to stop the timer. One approach is to cancel the $ timeout return promise (promise). module.controller (\u0026 quot; TestController \u0026 quot ;, function ($ scope, $ timeout) {var onTimeout = function () {$ scope.value + = 1; timer = $ timeout (onTimeout, 100);}; var timer = $ timeout (onTimeout, 100); $ scope.value = 0; $ scope $ on. (\u0026 quot; $ destroy \u0026 quot ;, function () {if (timer) {$ timeout.cancel (timer);}});}); five Event Top Scope 1. We should use the scope to communicate only event in the controller for the current screen single page of the application. If we only need to share data, then we should consider using the Services (service). 2. When a triggering event, unless the event we need to inform our entire application in all of the individual scope, otherwise we do not need at $ rootScope trigger event. If we only need to trigger the sub-scope, New Nike Free 5.0 V4 Purple Yellow Shoes on the current scope $ broadcast events. Parent scope using $ emit obtain the current scope events. This will also reduce the spread of events, rather than through the entire flow from top to bottom. 3. Services are at $ rootScope listen to events get notifications of choice. This is because the services in our Nike Free Run 3 Women applications initialized only once and did not get their own scope, it would be nice. Air Jordan Heel 4. Normally we should not be in the $ rootScope register event listeners (except service). This is a common cause of AngularJS application generates a bug. This is because when we add an event listener on a controller of $ scope, while the Air Max 2011 Womens Grey Green controller is destroyed (which we navigate away from the page, or close a section), the listener is also destroyed. When we add it to Mens Nike Free Run 3 Shoes Black 3 the $ rootScope, while leaving a navigation controller, listeners will be preserved and remain active and trigger. So we have to cancel the listener from $ rootScope manually, or simply not in order to secure the $ rootScope add a listener. But if we have to add an event to $ rootScope, do not forget that in the controller's scope in its removal. \u0026 Lt; strong \u0026 gt; Air Jordan Heel \u0026 lt; / strong \u0026 gt; var myEventHandler = $ rootScope $ on ('MyEvent', 'My Data');. $ Scope $ on ('$ destroy', function () {myEventHandler ();}).; 5. If we know that only a listener, and you have encountered. We can call on event.stopPropagation by the function passed to the event listener event object () to stop further spread of the event. Sixth, build business logic 1. Controllers should not be a reference to DOM, but only contain behavior, use the Directives (directive) do DOM manipulation. 2. Services should view logically independent .3. Do not fight with HTML, but by Directives extension. The best is to use a modular folder structure, so that we can create reusable components / can be distributed. Seven general rules 1. images using alternative ng-src src. 2. Use a promise to handle callback. AngularJS it has exposed the 2015 Nike Free 5.0 '$ q' service. Many AngularJS services return promises: $ http, $ interval, $ timeout. 3. Do not compress angular.min.js because AngularJS team already compressed files via predefined angular setting, if we re-compression may cause damage. So directly. 4. If the template (template) buffer is required to use $ templateCache cache html template. 5. always the third party API callback package to $ apply, to notify AngularJS change New Nike Free Run 3 Shoes Silver 3 on the environment. 6. If we do not allow users to load before AngularJS display HTML, use ng-cloak directive. \u0026 Lt; div class = \u0026 quot; session ng-cloak \u0026 quot; \u0026 gt; .............. content ............ \u0026 lt; / div \u0026 gt; .ng-cloak {/ * this will change to block when scope and angular is ready * / display: none;} 7 in order to prevent any conflicts, do not use the 'ng' prefix in our own directives. Create your custom. Best to use \u0026 lt; my-component \u0026 gt;, because \u0026 lt; my: component \u0026 gt; in IE sometimes go wrong. \u0026 Lt; my-component \u0026 gt; \u0026 lt; my:. Component \u0026 gt; 8 event in the application as a global related use $ broadcast (), $ emit () and $ on () (such as user authentication, or the application is closed). If we need specific event module, service or widget, we should select Services, Directive Controllers like. 9. Do not use the automatic off-label, because some browsers do not like them. Use '\u0026 lt; product-title \u0026 Air Jordan Outlet gt; \u0026 lt; / product-title \u0026 gt;' instead of '\u0026 lt; product-title / \u0026 gt;'.AngularJS best coding practice guidelines
