我正在尝试制作一个Cookie政策通知弹出窗口,它正是我想要的方式,并创建一个cookie。但是,由于我是javascript的新手(加上任何类型的编码),我不知道如何使用另一个搜索cookie“STLCSD”的脚本,如果它存在,则运行'hideDiv'函数。
我想避免使用HTML,CSS和JS以外的任何东西,因为这个企业使用的平台不支持其他任何东西。
非常感谢任何帮助。请询问任何进一步的细节
<script language=javascript type='text/javascript'>
function hideDiv() {
if (document.getElementById) { // DOM3 = IE5, NS6
document.getElementById('hideShow').style.height= '0px';
document.getElementById('hideShow').style.fontSize= '0px';
document.getElementById('hideShow').style.color= '#cddfea';
document.getElementById('hideShow').style.top= '-10px';
document.getElementById('hideShow').style.backgroundColor= '#cddfea';
document.getElementById('topbar').style.height= '1px';
}
else {
if (document.layers) { // Netscape 4
document.hideShow.height= '0px';
document.hideShow.fontSize= '0px';
document.getElementById('hideShow').style.color= '#cddfea';
document.getElementById('hideShow').style.top= '-10px';
document.getElementById('hideShow').style.backgroundColor= '#cddfea';
document.getElementById('topbar').style.height= '1px';
}
else { // IE 4
document.all.hideShow.style.height= '0px';
document.all.hideShow.style.fontSize= '0px';
document.getElementById('hideShow').style.top= '-10px';
document.getElementById('hideShow').style.color= '#cddfea';
document.getElementById('hideShow').style.backgroundColor= '#cddfea';
document.getElementById('topbar').style.height= '1px';
}
}
}
function cookiepolicy(){
days=50; // number of days to keep the cookie
myDate = new Date();
myDate.setTime(myDate.getTime()+(days*24*60*60*1000));
document.cookie = 'cookieName=STLCSD; expires=' + myDate.toGMTString();
}
</script>

<b>Cookie Policy</b>

答案 0 :(得分:2)
我使用了这样的函数:
function readCookie(cookieName)
{
if(document.cookie.length > 0)
{
var begin = document.cookie.indexOf(cookieName + "=");
if(begin != -1) {
begin = begin + cookieName.length + 1;
var end = document.cookie.indexOf(";",begin);
if (end == -1) end = document.cookie.length;
return unescape(document.cookie.substring(begin,end));
} else {
return "";
}
}
return "";
}
之后,你可以使用类似的东西:
if(readCookie("STLCSD") == "true") { hideDiv(); }
我希望它有所帮助!
