Parameter	Description
event	Yes select. Specifies one or more events to be removed from the element. Multiple event values separated by spaces. If only this parameter is specified, all functions bound to the specified event are removed.
function	Optional. Specifies the name of the function to unbind the specified event from the element.
eventObj	Optional. Specifies the removed event object to use. this eventObj parameters come from the event binding function.

#This method can also unbind the event handler through the event object. This method is also used to unbind events within itself (such as deleting the event handler after the event has been triggered a certain number of times).

When the unbind() method does not specify parameters, all event handlers of the specified element will be deleted.

Example:

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<script src="js/jquery-1.10.2.min.js"></script>
		<script>
			$(document).ready(function() {
				$("p").click(function() {
					$(this).slideToggle();
				});
				$("p").hover(function() {
					$(this).css("color","red");
				});
				$("button").click(function() {
					$("p").unbind();
				});
			});
		</script>
	</head>
	<body>

		<p>这是一个段落。</p>
		<p>鼠标移入任意段落(p 元素)，该段落字体颜色会变红。</p>
		<p>点击任意段落(p 元素)，该段落就会消失。</p>
		<button>移除所有段落(p 元素)的事件句柄</button>
