---restore content starts---When angular first entered the front-end developer Vision, one of the indelible impressions was its implementation of two-way data binding. This chapter first describes how to use this feature, and then explains in depth how its two-way binding mechanism is implemented.Data-binding in angular refers to the automatic synchronization between the model models and view views.

Angular JS is very good very powerful, but note that angular JS is not suitable for the operation of the DOM, although after a version of the update, angular built-in jqlite to facilitate the operation of the DOM, the intention to replace the location of jquery, it is very ulterior motives.In fact, angular the best pla

$http ServicesThe angular built-in $http service simply encapsulates the native XMLHttpRequest object of the browser and can communicate directly with the outside.The $http service can accept only one parameter, which is an object that mainly contains the configuration content of some HTTP requests. Such as: var req = {method: ' POST ' ' Content-typ E ': ' application/x-www-form-urlencoded ' ' Test ' You can see that the $http () method returns a

There have been a lot of problems with the recent use of the Select command in angular, which is depressing. After looking at a lot of data, it was not easy to find the Select command, and decided to summarize. 　　Select usage: 　Attribute Description: Discovery and no Ng-change attribute Ng-required: When the property value is true, add required validation to select, False when not validated. Ng-options: Specifies the data source to g

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
