jQuery on() method:
The on() method is used to attach event handlers to the selected elements. The on() method replaces delegate(), bind(), and live() methods. This method is recommended to be used as it simplifies the jQuery code base. We can use the off() method to remove the event handlers attached by the on() method.
It is an inbuilt method in jQuery. The syntax of using the on() method is given as follows -
Syntax
This method accepts five parameters in which one is mandatory, and others are optional. The parameter values of the on() method are defined as follows.
event: It is the mandatory parameter. This parameter specifies one or multiple events or namespaces to attach to the selected elements. If we have to specify multiple events, the event values must be separated by a space.
childSelector: It is an optional parameter. It specifies the child elements to which the event handler is to be attached.
data: It is also an optional parameter. It is the additional data to be passed to the handler when an event is triggered.
function(eventObj): It is also an optional parameter. It is the function to run when an event triggers.
map: It is the event map.
Now, let's see some illustrations to understand the use of the on() method.
Example1
In this example, there is an h3 heading element on which we are applying the on() method to attach the click event to it. We have to click the h3 element texted as Click me to see the effect.

After the execution of the above code, the output will be -

After clicking the given text Click me, an alert dialog box will be displayed as follows -
![jQuery on() method](https://static.javatpoint.com/jquerypages/images/jquery-on-method2.png)
Example2
In the previous example, we have attached a single event handler to the selector. But in this example we will see how to attach multiple event handlers to the selected element.
Here, there is a div element on which we are applying the on() method to add three events that are mouseover, mouseout, and click. When we move the cursor over the given text "This is a div element", the style and text of the element will get changed, and the events mouseover, mouseout, and click will be attached to it.

After the execution of the above code, the output will be -

When we move the cursor over the text This is a div element, the output will be -

After clicking the text Click me, the output will be -

Example3
In this example, we are attaching a custom event to the div element using the on() method.
