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:
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;
}
};
页面调用只要引进这个文件
$.cookie(\"name\"); //根据cookie名字取到cookie值
$.cookie(\"name\", \"value\");//设置cookie 名字,值
$.cookie(\"name\", value, { 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。
