<!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>
