为什么我点首先 ，框内不会跳出网页？
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
<script>
function onClick(){
document.getElementById("aa").src=s;
alert("123y");
}
</script>
<style type="text/css">
</style>
</head>
<body>
<iframe name="frame1" id="aa" style="width:100%;height:100%;" src="about:blank"></iframe>
<a href="" onClick="clickOne(*http://www.baidu.com*)">首页</a>
</body>
</html>
