1.第一種：使用jQuery的cookie庫
例子就是現在正在使用的js,相關代碼如下：
$(document).ready(function () {
var adCookie=$.cookie("docCookie");
//如果本地沒有cookie，將詞條cookie寫入本地
if(adCookie!="adDocCookie"){
$("#wapDocCookie").show();
}
//如果本地存在詞條cookie，不顯示浮層
if(adCookie=="adDocCookie"){
$("#wapDocCookie").hide();
}
//關閉廣告，隱藏浮層
$("#closeAd").click(function(){
$("#wapDocCookie").hide();
$.cookie("docCookie","adDocCookie",{expires:60});
});
});
//jQuery cookie library
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.第二種：自己寫一個js操作cookie的實例
相關js如下：
$(document).ready(function() {
function writeCookie(name,value)
{
var exp = new Date();
exp.setTime(exp.getTime() + 7*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
//讀取cookies
function readCookie(name)
{
var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");
if(arr=document.cookie.match(reg)){
return unescape(arr[2]);
}else {
return null;
}
}
var adCookie = readCookie("adCookie");
if(adCookie!="adDocCookie"){
$("#wapDocCookie").show();
}
//如果本地存在詞條cookie，不顯示浮層
if(adCookie=="adDocCookie"){
$("#wapDocCookie").hide();
}
//關閉廣告，隱藏浮層
$("#closeAd").click(function(){
$("#wapDocCookie").hide();
});
});
</pre>
</div>
