In jquery, bind means "bind" and is used to bind events to specified elements and to set one or more event handlers.

The bind () method adds one or more event handlers to the selected element, as well as functions that run when the event occurs.

The syntax for binding events and functions to elements:

The $(selector) .bind (event,data,function) parameter describes event

Necessary. Specifies one or more events to be added to the element.

Multiple events are separated by spaces. Must be a valid event.

Data is optional. Specifies the additional data passed to the function. Function is required. Specifies the function to run when an event occurs.

Example 1: bind the click event and set the handler

Effect achieved: hide or show the p element when the mouse is clicked

$(document) .ready (function () {$("button") .bind ("click", function () {$("p") .slideToggle ();}) Hide or show the p element.

This is a p paragraph.

This is a p paragraph.

Example 2: bind multiple events

Move the mouse over the paragraph.
