js实现登录时记住用户名

在页面中如何获取cookie值呢?

如果是JSP的话,可以通过servlet的对象request 获取cookie,可以

参考:http://hw1287789687.iteye.com/blog/2050040

如果要求登录页面是html呢?html页面中如何获取cookie呢?

直接上代码了

页面:loginInput.html

代码:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html><head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<!-- base href="http://localhost:8080/shop_goods/" -->

<title>user login</title>

<!--

<style type="text/css">
.errorMessage li {
	list-style-type: none;
	margin-left: 0
}
</style>
</head>

<body>

<script type="text/javascript">
//获取cookie的值
function getCookie(cookieKey){
	var cookies = document.cookie ? document.cookie.split('; ') : [];

	for (var i = 0, l = cookies.length; i < l; i++) {
		var parts = cookies[i].split('=');
		if(parts.length>1){
			if(parts[0]==cookieKey){
				//username1=;
				return parts[1];
			}
		}
	}
	return '';
}
var username1='';
window.onload=function(){
	//cookie的key是'userEmail'
	username1=getCookie('userEmail');

	//alert("username1:"+username1);
	var issave222=com.whuang.hsj.$$one("issave");
	if(username1){
		if(username1!='' && username1!=null &&username1!=undefined){
			com.whuang.hsj.$$one("user.username").value=username1;
			issave222.checked=true;
		}else{
			issave222.checked=false;
		}
	}else{
		issave222.checked=false;
	}
}
</script>
	This is login page.
	<br>
	<a href="/shop_goods/">index</a>
