复制代码代码如下:

<!DOCTYPE html> 
<html> 
<head> 
<title>cookies.html</title> 

<meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> 
<meta http-equiv="description" content="this is my page"> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"> 

<style type="text/css"> 
.txt{

height:20px; 
border: 1px blue solid; 
border-radius:0.5em; 
margin-bottom: 5px;

} 

</style> 
<script type="text/javascript" src="../js/jquery-1.10.2.js"></script> 
<script type="text/javascript" src="../js/jquery.cookie.js"></script> 
<script type="text/javascript"> 
$(function(){ 


if($.cookie("name")){ 
//取值如果存在则赋值 
$("#username").val($.cookie("name")); 

} 


$("#mycookie").submit(function(){ 

//如果选中了保存用户名选项 
if($("#chkSave").is(":checked")){ 

//设置Cookie值 
$.cookie("name",$("#username").val(),{ 
expires:7,//设置保存期限 
path:"/"//设置保存的路径 

}); 

}else{ 

//销毁对象 
$.cookie("name",null,{ 
path:"/" 

}); 
} 

return false; 
}); 

}); 


</script> 
</head> 
<body> 
<form action="#" id="mycookie">
