一直都是简单去js实现cookie的一些操作,今天把js对cookie操作系统的整理了一遍,包括:js读取cookie,js添加cookie,js删除cookie,示例如下:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312" />
<title>cookie处理函数练习(为我所写，非我所想:改善面向对象)</title>
<script language="JavaScript" type="text/javascript">
function addCookie(objName,objValue,objHours){//添加cookie
var str =; expires=" + date.toGMTString();
}
document.cookie = str;
alert("添加cookie成功");
}
function getCookie(objName){//获取指定名称的cookie的值
var arrStr = document.cookie.split("; ");
for(var i = 0;i < arrStr.length;i ++){
var temp = arrStr[i].split("=");
if(temp[0] =="){
str = "没有保存任何cookie";
}
alert(str);
}
function $(m,n){
return document.forms[m].elements[n].value;
}
function add_(){
var cookie_name = $("myform","cookie_name");
var cookie_value = $("myform","cookie_value");
var cookie_expireHours = $("myform","cookie_expiresHours");
addCookie(cookie_name,cookie_value,cookie_expireHours);
}
function get_(){
var cookie_name = $("myform","cookie_name");
var cookie_value = getCookie(cookie_name);
alert(cookie_value);
}
function del_(){
var cookie_name = $("myform","cookie_name");
delCookie(cookie_name);
alert("删除成功");
}
</script>
</head>
<body>
<form>
<div><label for="cookie_name">名称</label><input type="text" /></div>
<div><label for="cookie_value">值</lable><input type="text" /></div>
<div><label for="cookie_expireHours">多少个小时过期</lable><input type="text" /></div>
<div>
<input type="button" value="添加该cookie" />
<input type="button" value="读取所有cookie" />
<input type="button" value="读取该名称cookie" />
<input type="button" value="删除该名称cookie" />
</div>
</form>
<hr />
</body>
</html>
