本文实例讲述了jQuery.cookie.js实现记录最近浏览过的商品功能。分享给大家供大家参考，具体如下：

1、jquery.cookie.js

/*jquery.cookie.js */

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;

}

};

2、实现最近浏览过的商品

var cookieName = "PrdIDCookie"; //cookie名称

var nid; //最新访问的商品ID

var N = 5; //设置cookie保存的浏览记录的条数

//记录最近浏览过的商品

function HistoryRecord() {

var historyp;

nid = $("#PrdID").val();

if (nid == null || nid == "") {

return;

}

//判断是否存在cookie

if ($.cookie(cookieName) == null) //cookie 不存在

{

//创建新的cookie,保存浏览记录

$.cookie(cookieName, nid, { expires: 7, path: '/' });

}

else //cookies已经存在

{

//获取浏览过的商品编号ID

historyp = $.cookie(cookieName);

};

//分解字符串为数组

var pArray = historyp.split(',');

//最新访问的商品编号放置载最前面

historyp = nid;

//判断是该商品编号是否存在于最近访问的记录里面

var count = 0;

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

if (pArray[i] != nid) {

historyp = historyp + "," + pArray[i];

count++;

if (count == N - 1) {

break;

}

}

}

//修改cookie的值

$.cookie(cookieName, historyp);

}

//获取最近浏览过的商品

function BindHistory() {

var historyp = "";

if ($.cookie(cookieName) != null) //cookie 不存在

{

//获取浏览过的商品ID

historyp = $.cookie(cookieName);

}

if (historyp == null && historyp == "") {

return;

}

else

{

var prdIDs = []; //将商品ID以列表或数据的方式保存

var pArray = historyp.split(',');

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

if (pArray[i] != "") {

//alert(pArray[i]);

prdIDs.push(pArray[i]);

}

}

//--->请求商品详细详细...

}

}

希望本文所述对大家jQuery程序设计有所帮助。
