Definition and usage

toggle() method is used for binding Two or more event handlers functions to respond to the click event of the selected element in turn.

This method can also be used to switch the hide() and show() methods of the selected element.

Bind two or more functions to the Toggle event

When the specified element is clicked, switch between two or more functions in turn.

If more than two functions are specified, the toggle() method will toggle all functions. For example, if there are three functions, the first click will call the first function, the second click will call the second function, and the third click will call the third function. The fourth click calls the first function again, and so on.
