Jquery cookies操作
jQuery操作cookie的插件,大概的使用方法如下 $.cookie('the_cookie'); //读取Cookie值 $.cookie('the_cookie', 'the_value'); //设置cookie的值 $.cookie('the_cookie', 'the_value', {expires: 7, path: '/', domain: 'jquery.com', secure: true});//新建一个cookie 包括有效期 路径 域名等 $.cookie('the_cookie', 'the_value'); //新建cookie $.cookie('the_cookie', null); //删除一个cookie 设置一个名称为exist,值为exist的cookie: $.cookie("exist", "exist"); 设置一个名称为exist,值为exist的cookie,同时设置过期时间(expires属性)为7天: $.cookie("exist", "exist", { expires: 7 }); 设置一个名称为exist,值为exist的cookie,设置过期时间(expires属性)为7天,同时设置cookie的path属性为”/admin” $.cookie("exist", "exist", { path: '/admin', expires: 7 }); 读取Cookie: 读取名称为exist的cookie值: alert( $.cookie("exist") ); 删除cookie: $.cookie("example", null); 例如: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <script src="../Scripts/jquery-1.4.1.min.js"></script> <script src="../Scripts/jquery.cookie.js"></script> <script type="text/javascript"> $(document).ready(function () { var i = 1; //当点击按钮的时候隐藏《p》 $("#clk_Submit").click(function () { //判断是否存在cookies对象 if ($.cookie("exist") == null || $.cookie("exist") == "undefined") { //创建cookies对象并且给其赋值,设置了生命周期为7天 $.cookie("exist", i, { expires: 7 }); } //获取cookies值 i = $.cookie("exist"); //判断是否为0 if (i % 2 != 0) { $("p").hide(); } else { $("p").show(); } i++; //保存到cookies里面 $.cookie("exist", i); }) }); </script> </head> <body> <form id="form1" runat="server"> <div> <h2>This is a heading</h2> <p>This is a paragraph.</p> <p>This is another paragraph.</p> <button type="button" id="clk_Submit">Click me</button> </div> </form> </body> </html>
