jQuery.cookie的基本用法：
Include script after the jQuery library (unless you are packaging scripts somehow else):
<script src="/path/to/jquery.cookie.js"></script>
Create session cookie:
$.cookie("name", "value");
Create expiring cookie, 7 days from then:
$.cookie("name", "value", { expires: 7 });
Create expiring cookie, valid across entire site:
$.cookie("name", "value", { expires: 7, path: "/" });
Read cookie:
$.cookie("name"); // => "value"
$.cookie("nothing"); // => undefined
Read all available cookies:
$.cookie(); // => { "name": "value" }
Delete cookie:
// Returns true when cookie was successfully deleted, otherwise false
$.removeCookie("name"); // => true
$.removeCookie("nothing"); // => false
// Need to use the same attributes (path, domain) as what the cookie was written with
$.cookie("name", "value", { path: "/" });
// This won"t work!
$.removeCookie("name"); // => false
// This will work!
$.removeCookie("name", { path: "/" }); // => true
JQUERY的COOKIE实例
jquery的cookie插件可以方便操作cookie，首先引入jquery.cookie.js文件，可以去官网下载。
<script type="text/javascript" src="__STATIC__/common/js/jquery.cookie.js"></script>
以下使用jquery的cookie实现一个简单的功能，一个公共栏，可以点击展开或者收缩，第一次进入页面默认展开，第二次以后进入页面默认收缩，但是点击也可以展开。
通过jquery的cookie记录是否第一次访问界面：
<script>
(function($) {
var $trigger = $(".dz_box .dz_title");
var $view_cur = $(".dz_title a:first");
var $view = $(".dz_box .dz_info");
var uid = {$businesser_info["uid"]};
var has_read = $.cookie("gonggao_uid_" + uid);
if (has_read) {
$view.hide();
$view_cur.removeClass("wel_down01").addClass("wel_up01");
}else{
$view_cur.removeClass("wel_up01").addClass("wel_down01");
$.cookie("gonggao_uid_" + uid, "1");
}
$trigger.click(function () {
if ($view_cur.hasClass("wel_up01")) {
$view.slideDown();
$view_cur.removeClass("wel_up01").addClass("wel_down01");
} else {
$view.slideUp();
$view_cur.removeClass("wel_down01").addClass("wel_up01");
}
});
})(jQuery);
</script>
