<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
	<form>
	 姓名:<input name="a" type="text">
	 	<input type="button" onclick="window.location.href='b.html?a='+a.value" value="提交">
	</form>
</body>
</html>

b.html:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<script type="text/javascript">
	var wo1=String(document.location);
	var wo2=wo1.indexOf("=");
	var wo3=wo1.substring(wo2+1,wo1.length);
