JS操作Cookie 大全
2009-06-30 04:02:00 来源：WEB开发网将上面的几个js命名为cookie.js，下面演示其基本用法
<script type="text/javascript" src="cookie.js"></script>
<script type="text/javascript">
function foo()
{
var name = document.getElementById("name").value;
if(name)
{
setCookie("name",name);
}
document.getElementById("show").innerHTML+=("NEWEST NAME :"+ getCookie("name") + "<br>");
}
</script>
Chapter 1.9 example
<br>
<input type="text" id="name" size="20" />
<input type="button" value="setCookie" onclick="foo()" />
<div id="show"></div>
