considered), at the end of the Addevent function, if the code is modified to the following: Element["on" + type] = Handleevent; if (!element.hasaddlistener) { element.addeventlistener (type,handleevent,false); Listen for events Just add one more time element[' hasaddlistener ' = true; } Although the above approach is a bit repetitive, the basic logic needs to be judged, but this is very close to the event Add method in JQuery. In other words,

The operations on events are nothing more than addEvent, fireEvent, and removeEvent. Generally, lib extends the functions provided by the browser to solve problems such as compatibility Memory leakage. The third problem is how to get the domReady status.6.1 event packages Browser event compatibility is a headache. The IE event is in the global window, while the m

the results. And I'm going to take you from the source point of view analysis, I believe you can more profoundly understand the Android event distribution mechanism. Reading source is fastidious, gradual, so we also from the simple beginning, this article first take you to explore the view of the event distribution,

Exploring vue source code-Event System This code is located in vue/src/CORE/instance/events. js After the lifecycle, You need to initialize the attributes and methods related to the event. The code of the entire event system is very short compared to other modules. Let's take a look at its implementation in several par

It is also a heavy function point. Analyze the architecture before analyzing the source code to help understand the source code. In fact, before the advent of jquery, Dean Edwards's Cross-browser Addevent () design was already excellent, and the design idea of the jquery event system was based on that idea, so let's analyze the

This article mainly introduces the jQuery1.9.1 source code analysis series (10) Event System's active event triggering and Simulation of bubble processing related information. For more information, see the following: stopPropagation: function() { var e = this.originalEvent; ... if ( e.stopPropagation ) { e.stopPropagation(); } JQu

>= Te->when_ms)) {//In the callback handler, it is possible to add a new timer event, if you continue to join, there is a risk of a dead loop, so you need to avoid this situation, each cycle does not handle the newly added events, which is implemented by the following code. if (Te->id > Maxid) { te = te->next; Continue; }The event Loop section is analyzed to t

There are several outstanding features of JQuery's event binding:1. Can bind an unlimited number of processing functions2. Events can be delegated to an ancestor node, not necessarily tied to the corresponding node, so that the added node can be processed as well.3. Chain-Operated　　The following is the principal analysis of the event's delegate design. The event source
