This article mainly introduces the asynchronous Script Loading Method of javascript with callback functions, and analyzes in detail the definition and usage skills of javascript callback functions for asynchronous loading in the form of examples, for more information about how to load
Web page interaction becomes more and more complex, and JavaScript asynchronous operations become more and more complex. For example, a common ajax request needs to respond to the operation when the request is complete. The request is usually asynchronous and other operations can be performed by the user during the req

This example describes the asynchronous script loading method for JavaScript with callback functions. Share to everyone for your reference. The implementation methods are as follows:
var Loader = function () {}
Loader.prototype = {
require:function (scripts, callback) {
This.loadcount = 0;
this.totalrequired = scripts.length;
This.callback

thread, all asynchronous events (such as mouse clicks and timers) are executed only when they have execution opportunities.
There is a lot of information to understand in this chart. If you fully understand them, you will have a good understanding of how the JavaScript engine implements asynchronous events. This is a one-dimensional icon: the vertical direction

I think the title is still quite long. There are many other functions. In fact, the simplification is just a function. asynchronous form submission only supports
AJAX = Asynchronous JavaScript and XML (asynchronous JavaScript and XML).AJAX is not a new programming language, but a new method of using existing standards.The biggest advantage of AJAX is that without reloading the entire page, you can exchange data with the server and update some of the Web content.AJAX does not re
Refers to a web development technique that creates an interactive Web application.AJAX is not an acronym, but a noun created by Jesse James Gaiiett.Does not refer to a single technology, but organically utilizes a range of related technologies:The representation of the Web Standard (standards-based Presentation) Xhtml+css,Use the DOM (Document Object Model) for dynamic display and interaction,Using XML and XSLT for data exchange and related operations,Use XMLHttpRequest for
C ++ asynchronous programming library based on Fiber (I): Principle and example, fiber asynchronous
Fiber and coroutine are similar concepts, such as user-level threads or light threads. Windows provides a set of APIS for users to create and use fiber courses. The libraries in this article are implemented based on this set of APIs. Therefore, they cannot be used
Asynchronous script loadingProblem:Solution:Divide and conquer the script;The script that makes the page look good and better is loaded immediately, and the script that is loaded later can be loaded later.The Async/defer property of HTML5? Typical and non-blockingIdeally, the script should be loaded at the same time as the document is loaded without affecting the rendering of the DOM.This allows the script to run once the document is ready because the
exception is not captured, most JavaScript environments provide a useful stack trace. For example, the following code throws an exception because '{' is an invalid JSON object.
function JSONToObject(jsonStr) { return JSON.parse(jsonStr);}var obj = JSONToObject('{');//SyntaxError: Unexpected end of input//at Object.parse (native)//at JSONToObject (/AsyncJS/stackTrace.js:2:15)//at Object. (/AsyncJS/stackTra
