I have implemented a mechanism to track the last visited page using cookies in my JavaScript code, triggered by onload. However, I am facing an issue where the script keeps refreshing repeatedly, almost as if it's triggered by mouse movement even though the only event used is onload.
Below is the snippet of my JavaScript:
<script type='text/javascript'>
//<![CDATA[
window.onload = function(event){
var currentPage = window.location.href;
var lastVisited = getCookie('udis');
var sessionId= getCookie('udisSession');
if(lastVisited === null || lastVisited === undefined){
setCookie("udis", currentPage, 365);
lastVisited = getCookie('udis');
}
if(sessionId === null || sessionId === undefined){
setSessionCookie('udisSession');
if(lastVisited !== currentPage){
window.location.href = lastVisited;
}
}
setCookie("udis", currentPage, 365);
updateBreadCrumb();
}
function getCookie(c_name) {
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++){
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name) {
return unescape(y);
}
}
}
function setSessionCookie(c_name){
document.cookie=c_name + "=" + 'testSession'+'; expires=; path=/';
}
function setCookie(c_name,value,exdays){
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}
//]]>
</script>
The scenario works perfectly on Firefox but unfortunately, it causes constant reloading in IE-8.
