multiple irp complete requests

requests for an interface, and you want all requests to complete before you proceed to the following operations.It is easy to think of a solution implemented through a thread group. The code is as follows:The printing results are as follows:There may not be a problem with the results, but it is important to note that Request1 request2 request3 are usually corres

Let your driver process multiple I/O requests at a time Your User-mode application sends a large number of I/O requests to your driver, but the driver keeps processing one request at a time. What is the problem? You may think that the driver is blocked in some fuzzy ways or the application requires more multithreading, but the solution is often much simpler: make

: This article mainly introduces how to use nginx to complete reverse proxy and process static file requests. if you are interested in PHP tutorials, refer to it. There are three main parts: nginx basic installation and use, reverse proxy and static file processing requests. 1. Installation and Use (windows) First Download nginx from here and install it as nee

Talking about how the Koa2 framework uses CORS to complete cross-origin ajax requests. There are many ways to implement cross-origin ajax requests. One of them is to use CORS, and the key to this method is to configure it on the server side. This article only describes the basic configurations that can complete normal

What does the "I/O Request" error below represent? 13:26:42. 480 spid364Microsoft SQL Server 2005-9.00.3177.00 (Intel x86) 16:30:02. 140 spid6sSQLServer has encountered 2 occurrence (s) of I/O requests taking longerThan 15 seconds to complete on file [F:/SQL data files/xxx.

we can use the 2nd approach, but we may only need to return the result after the last keystroke, so it would be wasteful to use the 2nd approach. Processing method: Leave the last request, cancel the request. Copy Code code as follows: (function ($) { var jqxhr = {}; $.ajaxsingle = function (settings) { var options = $.extend ({className: ' Defeartname '}, $.ajaxsettings, settings); if (Jqxhr[options.classname]) { Jqxhr[options.classname].abort (); } Jqxhr[options.

Done (function () {Alert ("Done");}). Fail (function () {Alert ("fail");});Second, ensure that all asynchronous AJAX requests are compl

Original article: jQuery: Multiple AJAX and JSON Requests, One CallbackOriginal Article Date: January 1, April 15, 2014Translated on: February 1, April 22, 2014Translated by: TieA common script file and a JSON stream to be loaded when I write code for Mozilla Developer Network (Mozilla Developer community. Because we use jQuery, this means we need to call jQuery. getScript and jQuery. getJSON functions. I k

In real business, it is often necessary to wait for several requests to complete before proceeding to the next step. However, synchronous requests are not supported in Angularjs $http.Workaround One:$http. Get (' Url1 '). Success (function (d1) { $http. Get (' Url2 '). Success (function ( D2) { // processing logic } );Workaround Tw

I used to develop a new function for Mozilla Developer Network. It needs to load a BASIC script file and a JSON request at the same time. Because jQuery is used, it means jQuery. getScript and jQuery. getJSON are used. I know that both are asynchronous and return a Deferred (Promise mode implementation in jQuery, see deffered object) object. Therefore, I want to know if I can request them in order in a callback, just like most JavaScript loaders (such as curljs ). I am lucky to use jQuery to pro

Script. readystate | 'loaded' = script. readystate | 'complete' = script. readystate ){FN FN ();Script. onload = script. onreadystatechange = NULL;Script. parentnode. removechild (SCRIPT );};};Script. src = URL;$ ('Head') [0]. appendchild (SCRIPT );} When the webpage needs to dynamically call multiple JS files, we can write as follows: Code highlighting

Click a button, then request resources to the server, without processing, many times there will be a number of requests waiting. We know that in general we use AJAX is asynchronous request, then we quickly repeated click on a button to get the results we do not know which is the result of the click may be the first time may be the last time may be the second time. So how do we solve this problem, the simple brute method is to send the request when the

I know that these functions are executed asynchronously (asyncronously) and will delay the return for some time, so I wonder if there is a way that I can use a single callback to load them in parallel, just as the JS loader Curljs does. Very lucky! With Jquery.when, I can load two requests concurrently and perform only one callback! JQuery ScriptAs I mentioned, here are the use cases for loading scripts and a JSON resource: Copy Code code as fo

Processing displays a wait bar for Ajax requests until all AJAX requests are completed before closing the wait bar. Relatively simple, the source code is as follows (based on jquery)Based on jquery//starting from the first Ajax request to show the wait bar? The wait bar is closed until a series of Ajax requests are complete
