本文实例讲述了jQuery操作cookie的插件。分享给大家供大家参考，具体如下：
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();
}
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 {
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]);
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
};
调用也很方便：
//使用方法如下:
//设置cookie的键值对
//$.cookie('name', ‘value');
//设置cookie的键值对，有效期，路径，域，安全
//$.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
//读取cookie的值
//var account= $.cookie('name');
//删除一个cookie
//example $.cookie('name', null);
希望本文所述对大家jQuery程序设计有所帮助。
