Let's talk about your situation. The development front-end mainly uses bootstrap, jquery, and ajax. Effect animation form verification is jq. Thinkphp is used in the background. Search for a better front-end framework some time ago and see angular. However, after learning for a while, I feel very confused. That question and answer also read my own situation.

The MVC (Model-view-controller) pattern is a popular pattern in both the front and back of web development, Reactjs the View layer in the front-end MVC pattern, with a bit of a Controller layer feature, An HTML template that is equivalent to JavaScript writing. The data model and data binding are the advantages of angular, so angular and reactjs need to be integrated. However, Flux is a library that adapts

$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

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.
