Jquery method to remove mouse events:

Method 1: Use unbind() method

## The #unbind() method removes the event handler of the selected element.

This method can remove all or selected event handlers, or terminate the execution of the specified function when an event occurs.

ubind() works with any event handler attached via jQuery.

Example:

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8" />
		<script src="js/jquery-1.10.2.min.js"></script>
		<script type="text/javascript">
			$(document).ready(function() {
				$("p").click(function() {
					$(this).slideToggle();
				});
				$("button").click(function() {
					$("p").unbind();
				});
			});
		</script>
	</head>
	<body>
		<p>这是一个段落。</p>
		<p>这是另一个段落。</p>
		<p>点击任何段落可以令其消失。包括本段落。</p>
		<button>删除 p 元素的事件处理器</button>
	</body>
</html>

		<meta charset="utf-8" />
		<script src="js/jquery-1.10.2.min.js"></script>
		<script type="text/javascript">
			$(document).ready(function() {
				$("body").delegate("p", "click", function() {
					$(this).slideToggle();
				});
				$("button").click(function() {
					$("body").undelegate();
				});
			});
		</script>
	</head>
	<body>
		<p>这是一个段落。</p>
