【jquery写入读取cookies】jQuery写入读取Cookie插件详解

找了下关于jQuery操作cookie的插件,大概的使用方法如下
example $.cookie("the_cookie", "the_value");
设置cookie的值
example $.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
example $.cookie("the_cookie", "the_value");
新建cookie
example $.cookie("the_cookie", null);
删除一个cookie


代码如下

 

 代码如下

jQuery.cookie = function(name, value, options) {

if (typeof value != "undefined") { // name and value given, set cookie

options = options || {};

if (value === null) {

value = "";

options.expires = -1;

}

var expires = "";

if (options.expires && (typeof options.expires == "number" || options.expires.toUTCString)) {

var date;

if (typeof options.expires == "number") {

date = new Date();

date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));

} else {

date = options.expires;

}

expires = "; expires=" + date.toUTCString(); // use expires attribute, max-age is not supported by IE

}

var path = options.path ? "; path=" + options.path : "";

var domain = options.domain ? "; domain=" + options.domain : "";

var secure = options.secure ? "; secure" : "";

document.cookie = [name, "=", encodeURIComponent(value), expires, path, domain, secure].join("");

} else { // only name given, get cookie

var cookieValue = null;

if (document.cookie && document.cookie != "") {

var cookies = document.cookie.split(";");

for (var i = 0; i < cookies.length; i++) {

var cookie = jQuery.trim(cookies[i]);

// Does this cookie string begin with the name we want?

if (cookie.substring(0, name.length + 1) == (name + "=")) {

cookieValue = decodeURIComponent(cookie.substring(name.length + 1));

break;

}

}

}

return cookieValue;

}

};

 


然后看了下Discuz!中对cookie的操作方法
如下,发现少了个遍历用;分割的数组的处理

 

 代码如下

function getcookie(name) {

var cookie_start = document.cookie.indexOf(name);

var cookie_end = document.cookie.indexOf(";", cookie_start);

return cookie_start == -1 ? "" : unescape(document.cookie.substring(cookie_start + name.length + 1, (cookie_end > cookie_start ? cookie_end : document.cookie.length)));

}

 

function setcookie(cookieName, cookieValue, seconds, path, domain, secure) {

var expires = new Date();

expires.setTime(expires.getTime() + seconds);

document.cookie = escape(cookieName) + "=" + escape(cookieValue)

+ (expires ? "; expires=" + expires.toGMTString() : "")

+ (path ? "; path=" + path : "/")

+ (domain ? "; domain=" + domain : "")

+ (secure ? "; secure" : "");

}
