如果单击 X,我有一个跨度的促销标题。现在,当我刷新页面时,跨度又回来了。我需要 cookie 来记住跨度关闭的 24 小时。
这是我尝试但没有结果的方法:
html代码:
<div id=”span” class="promo_holder">
<a href="javascript:void(0)" id=”close” class="close_promo_header"
onclick="hidePromoPanel ('/');">Close<span>X</span></a>
</div>
JavaScript 代码:
$(document).ready(function() {
if (!readCookie('hide')) {
$('#span').show();
}
$('#close').click(function() {
$('#span').hide();
createCookie('hide', true, 1)
return false;
});
});
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);
}
