基于jquery的cookie的用法_jquery-JS Tutorial-php.cn

example $.cookie('name', ‘value');
设置cookie的值，把name变量的值设为value
example $.cookie('name', ‘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('name', ‘value');
新建cookie
example $.cookie('name', null);
删除一个cookie

var account= $.cookie('name');
取一个cookie(name)值给myvar

代码如下

复制代码代码如下:

        
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 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

复制代码代码如下:

        
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' : '');
        
}
