Events in jQuery

Events in jQuery

What are the events ?

Events are the some special moments on web pages, when a user do something or perform some action on a web page, these actions are called events.

These action may be of any action like press any key on keyboard, click mouse, double click mouse or submit a form and many more.

The term ‘fires’ or ‘fired’ is used with events which means happening an event. When an event performed or happened mean the events is fired.

Now if we talk about events in jQuery, We can divide events in some categories.

1. Mouse events

2. Keyboard events

3. Form events

4. Document events

Events in jQuery are methods or functions.

For every event there is a function related to that event and that function or method is used to apply that event on any element on a web page.

The syntax for the above will be –

Syntax - $(“element”).event_method() ;

If we want to perform some action when an event fires, we have to use a function for that action. The syntax for this will be –

$(“element”).event_method(function(){

// The action goes here…

});

Now we will discuss each of those categories one by one in detail in coming chapters.
