这段代码哪里有问题呢?
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>鼠标移开事件 </title>
<script type="text/javascript">
function message(){
alert("不要移开,点击后进行慕课网!");
}
function newpage(){
var newlinl=window.open("http://www.hao123.com" "_blank" "width=500px,height=400px")
}
</script>
</head>
<body>
<input type="button" value="hao123" title="点击进入hao123" onclick="newpage()">
<form>
<br />
<a href="http://www.imooc.com" onmouseout="message()">点击我</a>
</form>
