This article is primarily geared towards those who are just beginning to learn angularjs and want to understand how data binding (data-binding) works,If you are already familiar with how to use ANGULARJS, I strongly advise you not to read it.Angularjs users want to know how data-binding works, they encounter a lot of terminology.such as $wacth, $apply, $digest, dirty-checking (dirty value detection) ... Wait, what are they doing?In this article I will solve all the questions and learn by combini

Module is an important modular organization in angular, which provides a set of cohesive business components (Controller, service, filter, directive ...). ) The ability to encapsulate together. Doing so allows the code to be encapsulated in a module based on the business domain problem, then injecting its associated module content with the dependency of module, allowing us to better "separate the focus" and achieve better "high cohesion and low coupli
ANGULAR JS POST data, the default is to send the JSON data to the server.var params={defid: "1234"};$http. Post (Url,params). Success (function (data, status, headers, config) {});We use Request.getparmeter ("Defid") when we obtain data from the server;In this way we are not getting the data.There are two ways to solve this problem:1. Resolve on the service sideHow to use the service side:String json=fileutil.inputstream2string (Request.getinputstream
1. $q
$Q is a built-in service for angular that enables you to perform functions asynchronously and allows you to use the return value (or exception) of a function when the function is executed.
2. Defer
The literal meaning of defer is delay, $q. Defer () You can create a deferred instance (a deferred object instance).
The deferred instance is designed to expose a derived promise instance, as well as a signal API that is used as a successful or un

The modal of the Angular UI will report the following error when written in the official documentation

Realization of the principle of the triangle: 1,div border generation is outward, 2, when the Div has adjacent border, the corner will be in a half of the triangle together. So when the width of this div is 0 and 0 o'clock, if it has four border words, it will form a square, each side is a isosceles triangle, at this time if any three sides of the two side of the look of the transparent color (transparent), the remaining side is a isosceles triangle.With the Angle box realization principle: Uses

So can also adopt ng+ conventional development mode, some important pages do not use this page to render SEO way, or set up a special SEO information page; So in this sense, the use of NG framework to do the app (ionic) is very appro

You need a control to enter minutes and seconds in a project, but after investigating some open source projects, you don't find the right controls. There is a similar control timepicker in the angular Bootstrap UI, but it has no depth to the precision of minutes and seconds.So decide to refer to its source code and implement it yourself.The final effect is as follows:
The first is the definition of the directive:
App.directive (' Minutesec

Default in Ng-repeat every item should be guaranteed to be unique, otherwise console will play out the error to tell you which Key/value is repeated. Such as:$scope. Items = [' Red ',' Blue ',' Yellow ',' White ',' Blue '];This array, blue, repeats, so the HTML traverses it.The console throws an error:

Angular Templates Data bidirectional bindingThe template (so-called template is HTML with markup and directives not compiled) is compiled in the browser,The compilation process produces a dynamic view, and any changes to the view are mapped directly to the model, and any changes on the model are synchronized to the view. Model is a one-way source application state, greatly simplifying the developer's programming model. You can think of view as a simpl
