I have a loading overlay that shows some information and I have a button to refresh the page. But I want the loading overlay only to appear once, not every time the button is clicked. (F5 doesn't matter). I was thinking of something like this:
<button type="button" onclick="reload();">
function reload() {
if (window.location.reload()) {
document.getElementById('loading').style.display = 'none';
}
}
But it doesn't work... pls help
You can make use of client cookie, set a flag to client cookie if overlay already shown once, example code:
Vanilla JS Version
<script>
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = "expires="+d.toUTCString();
document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}
function getCookie(cname) {
var name = cname + "=";
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);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
if (getCookie('OVERLAY_ALREADY_SHOWN')) {
document.getElementById('loading').style.display = 'none';
}
else {
// ... some conditions ...
setCookie('OVERLAY_ALREADY_SHOWN', true, 14); // persist two weeks
}
</script>
jQuery Cookie Version
<script src="/path/to/jquery.cookie.js"></script>
<script>
if ($.cookie('OVERLAY_ALREADY_SHOWN')) {
document.getElementById('loading').style.display = 'none';
}
else {
// ... some conditions ...
$.cookie('OVERLAY_ALREADY_SHOWN', true, { expires: 14 }); // persist two weeks
}
</script>

I am trying to only display a pop up on the first page load, but in my current script it only shows the pop up if you refresh the page. The popup should display the first time you come to the page but not again.
<script type="text/javascript">// <![CDATA[
document.addEventListener('DOMContentLoaded', function() {
function setCookie(cname,cvalue,exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires=" + d.toGMTString();
document.cookie = cname+"="+cvalue+"; "+expires;
}
function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return '';
}
$(document).ready(function() {
if(getCookie('popup') !== ''){
$('.popup-wrapper').css('display','block');
} else {
setCookie('popup','open',1);
}
$('.popup-close').click(function(){
setCookie('popup','close',1);
$('.popup-wrapper').css('display','none');
});
});
});
// ]]></script>
Any help would be greatly appreciated.
Is there a reason why you are using cookies?? If not you can use localStorage and write something a bit cleaner..
So for example
$(document).ready(function() {
// if localStorage doesnt have the shownPopUp item
if(!localStorage.getItem('shownPopUp')){
$('.popup-wrapper').css('display','block');
}
$('.popup-close').click(function(){
// set the shownPopUp item in localStorage
localStorage.setItem('shownPopUp', true)
$('.popup-wrapper').css('display','none');
});
});
});
No need for the getCookie function
Cookies are more used for server-side functions, where localStorage is better for client-side functions. So what will happen here is your users will never see the popup again unless they delete there localStorage
Just add localStorage.setTtem after showing the popup. And don't forget to make the .popup-wrapper display:none
if(!localStorage.getItem('shownPopUp')){
$('.popup-wrapper').css('display','block');
localStorage.setItem('shownPopUp', true);
}
How to disable popup from showing up on given page for 2 days after I click .popup-close on first visit to that page ?
This is my code https://jsfiddle.net/4q1aL8pL/2/
I've tried localstorage between lines 122-140 in my code. I am javascript beginner please help :)
Maby there has to be some timer applied which will count to 2 days hours worth ?
//<![CDATA[
var n = Number(localStorage.getItem('odometerValue')) || 0;
var m = localStorage.getItem('displayNone');
var myOdometer;
function startcounting () {
var div = document.getElementById("odometerDiv");
myOdometer = new Odometer(div, {value: n, digits: 6, tenths: true});
myOdometer.set(n);
update();
}
function update () {
n=n+0.01
myOdometer.set(n);
localStorage.setItem('odometerValue', n);
localStorage.setItem('displayNone', m);
setTimeout(update, 200);
}
//]]>
you can use the local storage to save the date of when the pop up loaded.
var d = new Date();
this will stamp the current date then all you have to do is check with the date of the visitor again and if you minus them and it equals 2 days pop up again.
Here is a function for using cookies.
/* Show popup if cookie doesn't exist. Will hide for 2 days if closed */
var PopUpCookie = getCookie("MyPopUpCookie");
if (PopUpCookie == '') {
$('#odometerDiv').show();
} else {
$('#odometerDiv').hide();
}
}
$('.popup-close').on('click', function () {
$('#odometerDiv').hide();
setCookie("MyPopUpCookie", "hide");
});
function setCookie(cname, cvalue) {
var d = new Date();
d.setTime(d.getTime() + (2*24*60*60*1000)); /* 2 days */
var expires = "expires=" + d.toUTCString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}
function getCookie(cname) {
var name = cname + "=";
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);
if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
}
return "";
}
I have a splash page where the user chooses between 2 experiences. once chosen, a cookie is added so they will always get that experience (or at least for the next 30 days). however, if a user comes to the site directly to a sub-url and bypasses the splash page, they should be automatically added to the default experience and get the default cooke (theme1). everything except the default cookie part is working.
here's what i have:
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;
}
$('.theme2').click(function() {
createCookie('chooseTheme','chosenTheme2',30)
});
$('.theme1').click(function() {
createCookie('chooseTheme','chosenTheme1',30)
});
var x = readCookie('chooseTheme');
if ($.cookie('chooseTheme') === null) {
createCookie('chooseTheme','chosenTheme1',30);
}
if (x.indexOf('chosenTheme1') > -1) {
$('body').addClass('themeOne');
} else if (x.indexOf('chosenTheme2') > -1) {
$('body').addClass('themeTwo');
}
thanks!
Try running a loop that updates every 1 minute. During the update, it triggers the function that checks for the cookie like the following:
setInterval(checkCookie(), 60000);
//the 60000 is for 60000 milliseconds which is 1 minute.
function checkCookie() {
var x = readCookie('chooseTheme');
if ($.cookie('chooseTheme') === null) {
createCookie('chooseTheme','chosenTheme1',30);
}
if (x.indexOf('chosenTheme1') > -1) {
$('body').addClass('themeOne');
} else if (x.indexOf('chosenTheme2') > -1) {
$('body').addClass('themeTwo');
}
}
Then add the code above into your code and it will check for the theme every 1 minute. I hope this helps you.
I've found similar code elsewhere on this site but can't get it to work for my situation.
I'm trying to delay showing a div (8 second delay in this case) to NEW visitors but if cookie is set then show the div immediately to RETURNING visitors.
Currently, it seems that the first part works--showing the div to new visitors after 8 seconds--and my code sets the cookie but the second part--showing the div immediately to returning visitors--doesn't work at all and, in fact, NEVER seems to show the div content.
I've tried everything I can think to move around but no luck.
Here's the relevant code (including cookie code) all placed in the HEAD section:
<script type="text/javascript">
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;
}
</script>
<script type="text/javascript">
function showbox() {
document.getElementById("show-this").style.visibility = "visible";
}
if (!readCookie('visitedPreviously')) { //if he/she is a new user
setTimeout("showbox()", 8000); // after 8 secs createCookie('visitedPreviously', 'visitedPreviously', 3); // 365 days persistence
}
</script>
<div id="show-this" style="visibility: hidden"><div class="center-this"><img src="mysource" alt="some text" /></div>
</div>
I've tried moving the "function showbox" to the BODY, tried if/else statements inside that function, moving code to a .js files, using css, and more but now I just need some help as I obviously don't know what I'm doing.
Thank you for your time.
if (!readCookie('visitedPreviously')) { //if he/she is a new user
setTimeout("showbox()", 8000); // after 8 secs
createCookie('visitedPreviously', 'visitedPreviously', 3); // 365 days persistence
} else {
showbox();
}
you just forgot the else :)
I'm trying to create a popup that opens after 30 seconds even if the user changes to a different page on the site.
e.g. User enters example.com and stays on the main page for 15 seconds, then navigates to a different page still on the site example.com, stays there for 15 seconds. Now I want the popup to open.
My JavaScript code to create a cookie:
<html>
<head>
<script>
var timeElapsed;
var targetTime = 10000;
var myInter;
function openPopup() {
alert('popup');
timeElapsed = 0;
clearInterval(myInter);
setCookie('alreadyDone', true, 1);
}
function updateCookie() {
timeElapsed += 2000;
setCookie('emailPopup', timeElapsed, 1);
alert(timeElapsed);
}
function checkCookie() {
if (getCookie('alreadyDone') === "") {
if (getCookie('emailPopup') === "") {
timeElapsed = 0;
setCookie('emailPopup', timeElapsed, 1);
} else {
timeElapsed = parseInt(getCookie('emailPopup'));
setCookie('emailPopup', timeElapsed, 1);
}
setTimeout(openPopup, targetTime - timeElapsed);
myInter = setInterval(updateCookie, 2000);
}
}
function getCookie(cname) {
var name = cname + "=";
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);
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = "expires=" + d.toUTCString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}
</script>
</head>
<body onload="checkCookie()">
<button>Page 1</button>
</body>
But I need this code run on every page on my site.
1) Create a js file called your-name.js
2) Cut this code and paste there. Save.
3) Call this file in every of your webpages like
<html>
<head>
<script type="text/javascript" src="/your-location/your-name.js"></script>
<head>
<body>
</body>
<html>
