Talking about the implementation of Winform events and the implementation of simulating their events, talking about the implementation of winform events
When we are new to Winform, we are attracted by its magical event functions. When we click a button, we will jump to the clicking method we wrote. However, this does not conform to our understanding of the method

Brief introduction
Understanding business processes, more agility, and near-real-time monitoring of management and compliance are growing business line requirements. Event-based Solutions support business and IT management enterprise risk by quickly and efficiently leveraging opportunities and reducing exceptions. When business event processing technology is combined with line-of-business applications, it creates an opportunity to build solutions that provide more flexibility and help detect cr
The off () function removes the event handler for one or more events bound by an element.
The off () function is primarily used to disassociate the event handler functions that are bound by the on () function.
This function belongs to the jquery object (instance).
Grammar
JQuery 1.7 adds this function. It is mainly used in the following two types of usage:
Usage One:

This article introduces the use of traditional events to simulate modern events, very simple and practical, the need for small partners can refer to.
As we all know, the modern event binding (attachevent) in IE has many problems compared with the standard of the AddEventListener.
For example: memory leaks, recurring events and triggers are flashback execution,
This blog is a presentation that describes using COOCS2DX Lua with touch events. For Main.lua files, look in the previous articles in the same series.
The underlying content will no longer be explained, and this article will focus on the content. Use the steps to create the listener you want (touch listener, Keyboard listener). Listener settings are swallowed. The listener sets the type of event to listen on (CC. Handler.event_touch_began), as well as
Online about this aspect of the code is more and more chaotic, here to tidy up and improve. Add Eventvar addevent = function (obj, type, fn) { if (obj.addeventlistener) obj.addeventlistener (type, FN, false); else if (obj.attachevent) { obj["e" +type+fn] = fn; Obj.attachevent ("On" +type, function () { obj["E" +type+fn].call (obj, window.event); });} ;removing eventsvar removeevent = function (obj, type, fn) { if (obj.removeeventlistener) obj.removeeventlist
The onfocus event is the event that occurs when the cursor falls in a text box.
The onblur event is the event that occurs when the cursor loses focus.
The following examples can be compiled

There are also the following examples

As we all know, the modern event binding (attachevent) in IE has many problems compared with the standard of the AddEventListener.
For example: memory leaks, recurring events and triggers are flashback execution, and so on.
The following is a traditional event method to handle the binding of an encapsulated event:
Addevent.id = 1;

Copy Code code as follows:
function Stopevent (evt) {
var evt = evt | | window.event;
if (Evt.preventdefault) {
Evt.preventdefault ();
Evt.stoppropagation ();
} else {
Evt.returnvalue = false;
Evt.cancelbubble = true;
}
}
Prevent events from continuing to propagate only (do not cancel the default behavior)

Details about mobile js touch events and js touch events
In mobile development, it is easier to design a prototype on the desktop, and then process the unique parts of the mobile device on the device to be supported. Multi-touch is one of the features that are difficult to test on a PC, because most PCs do not have touch input.
Tests that have to be performed on mobile devices may lengthen your development
