Menu
I'm trying to show a div element only once per time that the user is on the site. I've seen multiple answers to similar questions already, but none of them seem to work... I have a code written out, but it doesn't work... I got a part of the code from somewhere else (I can't remember) so is that why it doesn't work?
Here's the code
<script type="text/javascript">
//<![CDATA[
var once_per_session=1
function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
if (offset != -1) { // if cookie exists
offset += search.length
// set index of beginning of value
end = document.cookie.indexOf(";", offset);
// set index of end of cookie value
if (end == -1)
end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}
function alertornot(){
if (get_cookie('alerted')==''){
loadalert()
document.cookie="alerted=yes"
}
}
function loadalert(){
document.getElementById("popupp").style.visibility = visible;
if (once_per_session==0)
loadalert()
else
alertornot()
//]]>
</script>
<div class="popupp" style="visibility:hidden;">hi</div>
Do you think you could help me figure out what's wrong with it?
EDIT
I've got it! Here it is:
<script type='text/javascript'>//<![CDATA[
window.onload=function(){
(function() {
var visited = localStorage.getItem('visited');
if (!visited) {
document.getElementById("popupp").style.visibility = "visible";
localStorage.setItem('visited', true);
}
})();
}//]]>
</script>
</head>
<body>
<div id="popupp" style="visibility:hidden;">hi</div>
</body>

You could use localStorage instead, only when the user clears it out he will get the popup again (same with cookies) but its much simplier:
(function() {
var visited = localStorage.getItem('visited');
if (!visited) {
document.getElementById("popupp").style.visibility = "visible";
localStorage.setItem('visited', true);
}
})();
html:
<div id="popupp" style="visibility:hidden;">hi</div>
This way you get a lot of less code. Hope this helps.
