jQuery | unbind() Method

Last Updated : 20 Feb, 2019

The unbind() Method is an inbuilt method in jQuery which is used to remove any selected event handlers. This method can be used to remove particular event handler, or stop specific functions. It works on any event handler using an event object.

Note: If no parameters are provided, the method works on all event handlers from the specified element.
Syntax:

$(selector).unbind(event, function, eventObj)

Parameters: This method accepts three parameters as mentioned above and described below:

event: It is an optional parameter which is used to specify events (one or more) to remove them from the elements.
function: It is an optional parameter which is used to specify the name of the function to unbind from the specified event for the element.
eventObj: It is an optional parameter which is used to specify the event object to remove from the event binding function.
