我正在为网站创建登录和注册页面。我决定使用cookie来存储已注册的数据，而不是使用PHP。我到底怎么做？我有基本的详细信息，如姓名，姓氏，生日，用户名，电子邮件和密码。我想存储详细信息，以便当用户向网站注册时，他们可以使用他们注册的内容登录。这些都是以下面的形式完成的：
<form action="" method="post" name="form1" onsubmit="getdropdownvalue()">
<table bgcolor="white" width="700" border="0" align="center">

<col width="200">

我怎样才能做到这一点？有什么建议吗？
答案 0 :(得分：1)
如果您想在Cookie中保存表单数据（不建议按照评论中的说明），则必须使用以下JavaScript：
<script type="text/javascript">
var today = new Date();
var expiry = new Date(today.getTime() + 30 * 24 * 3600 * 1000); // plus 30 days
function setCookie(name, value)
{
document.cookie=name + "=" + escape(value) + "; path=/; expires=" + expiry.toGMTString();
}
function storeValues(form)
{
setCookie("field1", form.field1.value);// replace with your form fields
setCookie("field2", form.field2.value);
setCookie("field3", form.field3.value);
setCookie("field4", form.field4.value);
return true;
}
</script>
此外，您需要在点击表单提交按钮时调用setCookie函数，如下所示：
<input type="submit" onclick="storeValues(this.form)" value="Submit" />
