本文实例分析了jquery读写cookie操作。分享给大家供大家参考，具体如下：
jquery cookie需要脚本文件如下：
rush:js;">
jQuery.cookie = function(name,value,options) {
if (typeof value != 'undefined') {
options = options || {};
if (value === null) {
value = '';
options = $.extend({},options);
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;
}
};
rush:js;">
$.cookie("name"); //根据cookie名字取到cookie值
$.cookie("name","value");//设置cookie 名字，值
$.cookie("name",{ expires: 7 }); //设置cookie 名字，值，生命周期等属性
$.cookie("name",null); //根据cookie名移除cookie
希望本文所述对大家jQuery程序设计有所帮助。
