鼠标停在睁眼的图片上，图片会变成闭眼的效果

实现代码如下：

<!DOCTYPE html>
	<html>
	<head>
	<meta charset="UTF-8">
	<title></title>
	<script>

	//睁眼
	function openEye(){
	var eye = document.getElementById("eye");
	eye.src = "img/eye01.jpg";
	}

	//闭眼
	function closeEye(){
	var eye = document.getElementById("eye");
	eye.src = "img/eye02.jpg";
	}

	</script>
	</head>
	<body>

	<div onmouseover="closeEye()" onmouseout="openEye()" style="float: left;border: 1px solid #000000;">
	<img id="eye" src="img/eye01.jpg" width="200px" />
	</div>

	</body>
	</html>
