Two ways: Add events directly to objects, nodes add events
For example, to add an onclick event with an ID of TAB1
In the first case:
Copy Code code as follows:
var t = document.getElementById ("Tab1");
T.onclick = function tst () {
Alert (")";
}
Second case
Copy Code code as follows:
var TB = document.getElementById ("Tab1");

ADO WillChangeRecordset and RecordsetChangeComplete (recordsetevent) events
The WillChangeRecordset method is invoked before a pending operation changes the Recordset. The RecordsetChangeComplete method is invoked after the Recordset has changed.
Grammar
WillChangeRecordset AdReason, adstatus, precordset
RecordsetChangeComplete AdReason, perror, adstatus, precordset
Parameters
AdReason the Eventreasonenum value, specifying the cause of the eve
In event communication, the event sender class does not know which object or method will receive (process) the event it raises .. Net Framework defines a type (delegate) that provides mediation between events and event handlers. Technically, a delegate is a class that can save reference to a method. Unlike other classes, the delegate class has a signature and can only reference methods that match the signature. Although delegation has many other purpo
When talking about events, we must first talk about delegation! What is delegation? In fact, I cannot make it very clear. Try to explain it as much as possible.
How do we define a method? How to call a method? Think about the following content first.
Class
Test
{ Static Void Main () {StringMSG="Message";Methodname (MSG );} Static Void Methodname ( String MSG) {//Code} }
A delegate is a type of reference method. The delegate
Keyboard Events:The parameter is keyascii. Each time you press a key on the keyboard, the ASCII value of the corresponding key must be assigned to the parameter keyascii, and then perform the corresponding operation.
Keypreview: accepts Keyboard Events. By default, the keypreview attribute of the form is false, and only the form obtains the focus of the corresponding keyboard event. If the keypreview attribute of the form is true, the form intercepts

Copy Code code as follows:
The div and body events are all triggered when the span is clicked. To prevent this from happening

The usual event-triggering method in Ugui has been before, and now it's time to talk about another way to trigger events, which not only allows a 2D Ugui trigger but also allows a 3D object to trigger a method.
first write a script to write a log method that triggers the event, as follows:
Using Unityengine;
Using System.Collections;
public class Testtrigger:monobehaviour {

void Start () {

Oracle Internal Events:
Introduction: (Introduction)
There are four kinds of events:
Immediate dumps
Conditional dumps
Trace dumps
Events that change database behaviour
Each event has a number that is the same as the Oracle error message. Such as 10046 and ORA-10046
Each event has a level, which can be the following:
Range 1 to 10
Bit
an error is encountered during a user session. In addition, the user can generate the class file by performing an Oracle trace event (see later), which is saved in the directory specified by the User_dump_dest parameter in the file format oraxxxxx.trc,xxxxx as the process number (or thread number) for creating the file.
Second, Oracle tracking events
Oracle provides a class of commands to dump (dump) information contained within Oracle's various in

SQL Server Extended Events (Extended event) is a general event processing system for servers, an artifact that tracks the running state of a SQL Server system, and a logging tool that can completely replace SQL Trace (SQL Trace). Design features for extended events:
Because the extended event engine does not recognize events, the engine can bind any even
On Android, there are more than one way to listen for events that interact between users and applications. For events in the user interface, the listener method is to intercept these events from a particular view object that interacts with the user. The view class provides the appropriate means.
In the various view classes used to build layouts, you may notice t

Events are often triggered by actions or by browser functions, and the elements can also be triggered by JavaScript. Events are triggered by JavaScript, also known as simulations of events.
