回答1:

You can call .unbind() without parameters to do this:

$('p').unbind();

From the docs:

In the simplest case, with no arguments, .unbind() removes all handlers attached to the elements.

回答2:

As of jQuery 1.7, off() and on() are the preferred methods to bind and unbind event handlers.

So to remove all handlers from an element, use this:

$('p').off();

or for specific handlers:

$('p').off('click hover');

And to add or bind event handlers, you can use

$('p').on('click hover', function(e){
    console.log('click or hover!');
});

@jammypeach is right about on & off being the accepted methods to use. Unbind sometimes ends up creating weird behaviors (e.g. not actually unbinding events correctly).

To unbind all elements within the body, find them all and for each one turn off the click handler (what was the old unbind):

$("body").find("*").each(function() {
    $(this).off("click");
});

Also see how to save the events that you've turned off in this stack overflow question.
