Recently in learning to use angular, slowly from the jquery UI transformation to use NG development, found a lot of different points, continue to learn it; First create a service to be referenced in the controller in the project, there are several existing forms of Service, factory (), services (), constant (), value ();p rovider (), where provider is the most basic, Other services are based on this write, the specific difference here will not unfold

detailed angular ng built-in instructionsWe are in turn from the use of frequency high to low, the importance of the size to explain the various instructions. 1, Ng-repeat 1.1 General Usage This is a sample program for presentation. In real code development, we typically declare a variable to store the data that needs to be repeat. For example: var chars= [{' Alphabet ': ' K '},{' alphabet ': ' A '},{' alphabet ': ' V '},{' alphabet ': ' L '

Comparing different ideas and tools is a way to better understand them. In this article, I'll start with a list of tasks that need to be repeated when creating a Web application, and then show you how backbone and angular will help you do that. The problem we are trying to solve As a web developer, most of our work can be attributed to one of the following categories: Implementing Business logic Building DOM Implementing view logic (declarative a
