difference between angularjs 2 and 4

Comparison and analysis of the difference between $ http. post and jQuery. post in AngularJS, angularjshttp. post In many cases, we need to use ajax to submit post data. angularjs is similar to jq and has encapsulated post. However, jQuery post is much simpler and more user-friendly than angularjs post.

Directives are one of the techniques we use to extend browser capabilities. During DOM compilation, the instructions associated with the HTML element are detected and executed. This allows the instruction to specify the behavior for the DOM, or to change it.Angularjs has a complete and extensible set of instructions to help Web application development, which enables HTML to be transformed into a "domain-specific language (DSL)".Directives can be used as element names, attribute names, class name

', transclude:true, scope: {}, Templateurl: ' my-dialog.html ', link:function (scope, Element) { scope.name = ' Jeff '; } }; }) (Window.angular);　　Add scope:{} Here, in fact, can also be written as scope:true. This declaration indicates that directive has its own independent scope, but this scope replicates all variables in the external controller to its scope scope when the directive is instantiated. This will result in the final output or Tobias, not Jeff.

'). Success (function (data) {$scope. phones = data;});Replaced by:$scope. Phones = Phone.query ();We use this simple statement to query all the phones.Another very important note is that, in the above code, when the Phonelistctrl controller calls the phone service method, we do not pass any callback functions. Although this seems to be a synchronous return, it is not at all. The synchronization returned is a "future"-an object that populates the data when the XHR response is completed. Given t

specified to this route.The problem is that we say we can delay loading a secondbackendservice, using a completely different implementation: This will rewrite the first one! There is currently no way to do the same name with two different implementations of two services, which prevents a secure way to implement lazy loading from Angular 1. Angular 1.x multi-Dependency injection mechanismIn Angular 1, we can use different methods for injection in multiple places:By location injection in the link

As the question, I am engaged in a little mixed, who can be careful to talk about: 1, composer psr-0 and psr-4 In the difference; 2, psr-0 specifications and psr-4 specifications of the difference; 3. composer and php-fig. For example, I am a bit confused. Who can tell me ca

Title, I'm a little confused, who can say it carefully: 1, the difference between psr-0 and psr-4 in composer; 2, the difference between the psr-0 norm and the psr-4 norm; 3, composer and Php-fig, who indulge who. Reply content: Title, I'm a little confused, who can say

Most of the time we need to submit post data in Ajax, similar to ANGULARJS and the encapsulated post.But the post of jquery is obviously simpler and more humane than the angularjs.AngularJS:? 1234 $http.post(‘do-submit.php‘,myData).success(function(){//somecode}); Jquery:? 123 $.post(‘do-submit.php‘,myData,function(){//somecode}); Doesn't that look any different? However, the data submitt

Two four characteristics of Angularjs: two-way data binding(1) Direction one: The model data is bound to the view-then whenever the model has changed, the rendering in view will change immediately! Implementation method:{{}}, Ngbind, Ngrepeat, Ngif, Ngsrc, Ngstyle ... All implement the binding of direction 1.(2) Direction Two: Modify the View (Form control) to bind to the model-at any time thereafter, whene

who said that test work is relatively easy, recently familiar with a few case, almost not crazy. Recently it is intermittent to see my angularjs, always feel that they are still not getting started, it may be that they owe the front end of things too much, can not see a few lines of code there are several commonly used functions unfamiliar. I have seen the video of the desert, and I know some good features of Angu
