Creating a PubSub object is easy./redis-py with PUBSUB goals that can subscribe to channels and listen to new information. Here's how to create a pubsub:>>> r = Redis. Strictredis (...)>>> p = r.pu

a three-step plan: We need a method to bind the UI elements and attributes to each other.We need to monitor the changes in attributes and UI elements.We need to make all bound objects and elements aware of changes. There are still many ways to implement the above idea. A simple and effective method is to use the PubSub mode. This idea is simple: we use the data feature to bind HTML code. All JavaScript objects and DOM elements bound together will sub

implemented through callback. We first define a pubsub object, which contains three methods: subscription, unsubscription, and release. The Code is as follows: Var pubsub = {}; (Function (q ){ Var topics ={}, // array stored by the callback function SubUid =-1; // Release Method Q. publish = function (topic, args ){ If (! Topics [topic]) { Return false; } SetTimeout (function (){ Var subscribers = topic

JavaScript: Design Pattern-Observer PatternIntroduction The observer mode is also called the Publish/Subscribe mode. It defines a one-to-many relationship, allowing multiple observer objects to listen to a topic object at the same time, when the status of the topic object changes, all observer objects are notified so that they can automatically update themselves. Benefits of using the observer mode: Supports Simple broadcast communication to automatically notify all subscribed objects. After

takes 100ms and then setinterval and AJAX requests? This is easy if you understand the JavaScript event-driven mechanism. Leave a piece of code, let's try it for ourselves. Is that what everyone thinks? var obj = {"num": 1}, start = new Date;settimeout (function () {obj.num = 2}, 0); while (new Date-start Alert (json.stringify (obj)); Perhaps we can also think of some of the reasons behind the problems we usually encounter: Why is the setinterval execution interval less than settimeout in

use the PubSub mode. The idea is simple: we use data attributes to bind HTML code, and all the JavaScript objects and DOM elements that are bound together subscribe to a PubSub object. Whenever a JavaScript object or an HTML INPUT element is monitoring the changes in the data, the events bound to the PubSub object are triggered, so that other bound objects and e

Angular is a well-known front-end Framework. Many of its features are cool, such as bidirectional data binding, dependency injection, commands, MVC (or MVVM), template (a bit like handlebar ). However, two-way data binding is the most discussed. The core idea of this article is the observer mode (or publish and subscribe mode). The focus of this article is to discuss how to implement the observer mode, then we will discuss how to implement simple two-way data binding.First, let's take a look
