The core of LABJS is LAB (Loading and Blocking): Loading refers to asynchronous parallel loading, and Blocking refers to synchronous waiting for execution. Labjs through elegant grammar (script and wait) to achieve these two characteristics, the core value is performance optimization. LABJS is a file loader. Requirejs and SEAJS are modular loaders that advocate a modular development philosophy, and the core value is to make JAVASCRIPT modular develo

There are 2 ways to define a module in Requirejs: Simple key-value pairs and functional dependencies.1. simple Key-value pairs : A module contains only value pairs, no dependenciesDefine ({ color: "Black", size:1, method1:function () {}, method2:function () {}});This kind of writing is simple, but there are a lot of limitations, just define the module's return value, do not do some additional initialization work.It is more flexible to defi

If the AMD specification is used in Requirejs, there are not many problems in using it, and if you load a JS file that is not an AMD specification, you will need to use shim in require.Require.config ({ paths:{ jquery: "/js/jquery2.0", instorage: "/js/in/instorage", Product: "/js/ Product/product ", Cate:"/js/product/category ", }, shim:{ cate:{ deps:[], exports:" Category " }}}

Previously introduced REQUIREJS (modular development), you can look at, but not detailed, so today refer to the official website to introduce in detail:1. Load JS file:The goal of Requirejs is to encourage modularity of the code, which uses a script loading step that differs from the traditional Requirejs loads all the code with an address relative to BaseURL. Pa

What is Requirejs?Requirejs is a javascript written by the JS framework, the main function is to be based on different dependencies on JavaScript and other files to load work, can be easily understood as JS file loader, it is very suitable for use in the browser, It can ensure that the dependent JS file loading is completed before loading the current JS file, which in a large number of JS files in the proje

One of the most common JavaScript libraries today is RequireJS. Recently, I have used RequireJS for every project I have participated in, or I recommend adding RequireJS to them. In this article, I will describe what RequireJS is and some of its basic scenarios. Amp; nbsp; modular development is widely used in the pro

One or one step-by-step implementationBasic idea: 1, first develop a frame page, it can complete some basic business logic, and support the extension of the mechanism; 2, the business logic becomes complex, need to split part of the logic into the sub page, the child page on demand loading; 3, the child page of the display content has become complex, and need to be split, on-demand loading; 4, The contents of a subpage are complex to rely on external modules, and the angular module n

This article mainly introduces the use of Requirejs in JavaScript applications to implement lazy loading, JavaScript is a popular JS library, the need for friends can refer to the Both simple and complex web applications are made up of HTML, JavaScript, and CSS files. Developers typically use a third-party JavaScript framework such as jquery, knockout, underscore, etc. to improve development speed. Because these JavaScript frameworks are developed fo

The script script is extracted from the template page, and the JS module that needs to be relied on is loaded by JS current module. Load on demand. Routing is more c

The purpose of this article is to make home better understanding of the Mod, the reason for the introduction of REQUIREJS/SEAJS contrast is mainly to require a clearer comparison of application scenarios, not to compare the pros and cons, Requirejs and SEAJS are modular long road pioneers, salute them!A mod for an engineered living Modularity is a way of dealing with the decomposition of a complex
