    • This signature does not accept any arguments.

This method is a shortcut for .on( "click", handler ) in the first two variations, and .trigger( "click" ) in the third. The click event is sent to an element when the mouse pointer is over the element, and the mouse button is pressed and released. Any HTML element can receive this event. For example, consider the HTML:

1
2
3
4
5
6
<div id="target">
Click here
</div>
<div id="other">
Trigger the handler
</div>
Figure 1 - Illustration of the rendered HTML

The event handler can be bound to any <div>:

1
2
3
$( "#target" ).click(function() {
alert( "Handler for .click() called." );
});

Now if we click on this element, the alert is displayed:

Handler for .click() called.

We can also trigger the event when a different element is clicked:

1
2
3
$( "#other" ).click(function() {
$( "#target" ).click();
});

After this code executes, clicking on Trigger the handler will also alert the message.

The click event is only triggered after this exact series of events:

  • The mouse button is depressed while the pointer is inside the element.
  • The mouse button is released while the pointer is inside the element.

This is usually the desired sequence before taking an action. If this is not required, the mousedown or mouseup event may be more suitable.

Дополнительные замечания:

  • As the .click() method is just a shorthand for .on( "click", handler ), detaching is possible using .off( "click" ).
