我的上述代码有什么问题我的facebook喜欢popup是在每次页面加载到我的博客。
What's wrong with my above code my facebook like popup is called every time the page is loaded in my blog. I just to show only one time every 30 days.How i can do that?
推荐答案
你的特定实现看起来像是你检查'visited = false'
的cookie,但将cookie设置为'visited = true'
c $ c>如果语句永远不匹配。
Your particular implementation looks like it has you checking the cookie for 'visited=false'
, but setting the cookie to 'visited=true'
so your if
statement will never match.
这里是我使用的cookie函数,当我的环境还没有它们时:
Here are the cookie functions I use when my environment doesn't already have them:
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function eraseCookie(name) {
createCookie(name,"",-1);
}
一旦你有了这些,你可以这样做:
Once you have those, you can do this:
jQuery(document).ready(function() {
var visited = readCookie('visited');
if (!visited || visited !== "true") {
createCookie('visited', "true", 30);
$.colorbox({width:"400px", inline:true, href:"#exestylepopups"});
}
});
