before or after exchanging data with the backend 1.5 Conversion of request data and corresponding dataThe $http. Post and $http.put methods accept any JavaScript object (or string) value as their data parameter. If data is a JavaScript object, data is converted to a JSON string by default.As with the transform request data, the $http service attempts to convert the JSON string contained in the response to a JavaScript object, which occurs before a success or failure callback, and the defa

How to communicate with the server: 1.$http: It is simple to encapsulate the native XMLHttpRequest object of the browser. $http can only accept a function of one parameter, which is an object that contains the configuration content used to generate the HTTP request. This function returns a promise object that has a success and error two methods. $http ({method: ' GET ', url: '/api/users.json '}). Success (function (Data,status,headers,config) {///when the corresponding is ready to be called}). E

At any time, if we want to add global functions for the request, such as identity authentication and error handling, we can intercept the request before it is sent to the server or when the server returns it, it is a good implementation method. If we want to add global functions for the request, such as identity authentication and error handling, we can intercept the request before it is sent to the server or when the server returns it, is a good means of implementation.

Bidirectional binding Bi-directional binding is the most practical function of ANGULARJS, it saves a lot of code, so that we focus on data and views, do not waste a lot of code in the DOM monitor, data synchronization, about bidirectional update, you can look at the following figure: Data--> View Here we only demonstrate how to bind to the view after having the data. After clicking the button, the div content becomes dick, the effect

will not be executed. Therefore, in the development of the project, if there is no need to load the DOM at once, the ng-if can be used to prevent the NG event from occurring, thus speeding up the loading speed of the DOM. Especially when repeat, each data contains complex data structure when the effect is particularly obvious. When the value is true, the DOM node is created. so if you use instructions, templates to render additional information, such
