This article mainly introduces Deferred of deferred in jQuery. the promise () method reminds you to pay attention to deferred. promise () and jQuery's. the difference between promise () instance methods. For more information, see Deferred. promise () and. promise () These two APIs have almost the same syntax, but ther

Please continue with the last lesson.$. In the Deferred () method, there are two objects, one is the Deferred object and one is the Promise object.The Promise object has several methods: State,always,then,promise,pipe,done,fail,progress.The deferred object is in addition to all the methods of the Promise object (through Jquery.extend (obj, Promise), all methods o

of writing, will naturally form a multi-layered callback function nested, if the amount of code is more, the code readability and maintenance will be poor.For scenarios (2), the code may be more complex: A) A, B operations need to have a state variable, isADone isBDone The default value is false ; A succeeds isADone true , and B succeeds isBDone true ; b) need a piece of code to repeatedly detect the above 2 state variables, we call this behavior pending, and so on pending to 2 sta

In view of the inefficiency of the traditional forward rendering for multi-light source rendering, various deferred rendering methods have been proposed and widely used. For example, deferred shading and the subsequent deferred lighting. The most important difference between the deferred method and the traditional forw

Let's talk about the closure and constructor. Then let's take a look at the Deferred implemented by the closure and the deferred constructor. As we all know, there are two ways to get an object: constructor and closure. The two methods have their own advantages and use different scenarios, but from the perspective of appearance, there is a striking difference: the object created by the closure does not need

See the callback object for a lesson first. Deferred is a tool method that is added to jquery through extend. As shown below:Jquery.extend ({Deferred:function (func) {},When:function (Subordinate/*, ..., Subordinaten */) {}});First, to introduce the use of the following deferred:var cb = $. Deferred ();SetTimeout (function () {Alert (1);Cb.resolve ();},1000)Cb.done (function () {Alert (2);});The above code

JQuery. deferred I. PrefaceBefore jQuery1.5, if you need to perform multiple Ajax operations, we generally use the following two methods: 1). call Ajax in sequence $.ajax({ success: function() { $.ajax({ success: function() { $.ajax({ //callbacks... }); }); }); This method has poor code readability, low efficiency, and difficulty, making debugging and troubleshooting complicated. 2). call Ajax in parallel var promises = []; $.ajax({

8 in the morning by the URL to access the script, that is, to execute the php file, and, this link can not be interrupted, to continue!! Or it will be ineffective.PHP is a single-request execution, which is executed only if requested. Whether PHP can automatically execute a code periodically PHP is a need to trigger execution, there is no way to keep the execution of it, even if you use sleep, it still needs you to point it out first, it will always existThe method is to use a scheduled task, t

The Python Twisted framework uses the Deferred object to manage the callback function. First, we will throw some ideas about using callback programming: Activating errback is very important. Because errback has the same functions as other t blocks, you must ensure that they exist. They are not optional, but mandatory. Activation callback is not at the wrong time point as important as activation callback at the correct time point. Typically, callb

jquery deferred objects using the detailedjquery is developed very quickly, almost every half-year, a small version every two months. Each version will introduce some new features. What I want to introduce today is a new feature--deferred object that was introduced from the jquery version 1.5.0. This feature is important and the future will be the core approach to jquery, which radically changes how Ajax is

Before we talked about MochiKit deferred,jsdeferred, now talk about jquery Deferred. First, let's start with their differences:When the callback function is saved, MochiKit Deferred (Dojo Deferred) is saved with a 2-dimensional array with only two decimal groups, one for the successful callback, and one for the failure
