Wordpress Cookie to show certain code / shortcode once per visit - javascript

trying to solve this one and it's a doosey.
Basically I have a typeform popup show once specific pages to get feedback from users but it currently loads every time the page loads.
Would much rather users just see it once per visit.
I tried this with no luck:
<style type="text/css">
div#slider {
/* Hide the div */
display: none;
}
.typeform-share{
display:none;
}
</style>
<div class="slider"><a class="typeform-share button" href="https://sombees.typeform.com/to/xxxxx" data-mode="popup" data-auto-open=true data-hide-headers=true data-hide-footer=true data-submit-close-delay="0" target="_blank"> </a> <script> (function() { var qs,js,q,s,d=document, gi=d.getElementById, ce=d.createElement, gt=d.getElementsByTagName, id="typef_orm_share", b="https://embed.typeform.com/"; if(!gi.call(d,id)){ js=ce.call(d,"script"); js.id=id; js.src=b+"embed.js"; q=gt.call(d,"script")[0]; q.parentNode.insertBefore(js,q) } })() </script></div>
<script type="text/javascript">
var cookie = document.cookie;
if (cookie.indexOf('visited=', 0) == -1) {
var expiration = new Date();
expiration.setDate(expiration.getDate()+1);
document.cookie = 'visited=1;expires=' + expiration + ';path=/';
var element = document.getElementById('slider');
element.style.display = 'block';
}
</script>

Don't know much about Typeform, but testing this out I figured out what is wrong with your code.
So first of all you should wrap it in something like:
$(window).on('load', function(){ ... }
Now, second and most important thing is that Typeform does not display overlay or modal in the slider div, but in a newly created div which it puts at the end of the page.
Like you see in he picture above. In my case class of the div is .jktBHD but this can be different for you. I don't know.
So, knowing this you should change your code to something like this:
$(window).on('load', function(){
var cookie = document.cookie;
if (cookie.indexOf('visited=', 0) == -1) {
var expiration = new Date();
expiration.setDate(expiration.getDate()+1);
document.cookie = 'visited=1;expires=' + expiration + ';path=/';
//
// THE IMPORTANT PART
//
var element = document.querySelector('.jktBHD');
element.style.display = 'block';
}
})
<style type="text/css">
.jktBHD {
display: none;
}
</style>
I tested this out and it works for me. Hope it will work for you too.

How do I refresh an iframe of the current page with an interval?

I'm trying to use this script to iframe a page into itself, and refresh the iframe at an interval:
document.write('<iframe id="frame" src="' + window.location.href + '"><script>setInterval(function ()/{document.getElementById("frame").contentWindow.location.reload();},10000);</script>');
All it does is append '); to the end of the page.
I am using this as a script on someone else's page to auto refresh. If I just refreshed, the interval would have been destroyed.
So While I'm still unclear of what you're trying to get to with this and your question was rather unclear (in retrospect), I was curious about how can we solve this without creating an infinite loop.
window.top !== window.self
won't work because they are one and the same, so I figured that will use a hash on the original page, omit it from the child to differentiate one from its own clone.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>test</title>
</head>
<body>
<h1 id="h1"></h1>
<script type="text/javascript">
document.getElementById('h1').textContent = window.location.search;
</script>
<script type="text/javascript">
if (window.location.hash === '#origin') {
var ifr = document.createElement('iframe');
var props = {
src: window.document.location.href + '?r=0',
width: 500,
height: 300,
style: "border:1px solid red;width:500px;height:300px;"
}
for (var key in props) {
ifr.setAttribute(key, props[key]);
}
document.body.appendChild(ifr);
setInterval(function(){
var s = ifr.src.split('?r=')[0];
ifr.setAttribute('src', s + '?r=' + parseInt( Math.random() * 1000000))
console.log(ifr.src);
// you can skip this, but it illustrates the refreshes
document.getElementById('h1').textContent = ifr.src;
}, 2000);
}
</script>
</body>
</html>
You will have to run this on your own, the code snippet dislikes its attempt for redirect and I cannot disagree..., - NB: only ran it in Chrome, but there's much that should be different elsewhere
Also, just for the sake of clarity, if you save this as test.html then you should run it as path/to/your/file/test.html?r=378426#origin
Took a bit of a shortcut with how the query string is handled, but the gist of it is here.
Create an iframe object, add its properties then add to the DOM and finally reload the page with a new query string every so often
var ifr = document.createElement('iframe');
var props = {
src: 'http://example.com/?r=0',
width: 500,
height: 300,
style: "border:1px solid red;width:500px;height:300px;"
}
for (var key in props) {
ifr.setAttribute(key, props[key]);
}
document.body.appendChild(ifr);
setInterval(function(){
var s = ifr.src.split('?r=')[0];
ifr.setAttribute('src', s + '?r=' + parseInt( Math.random() * 1000000))
console.log(ifr.src);
}, 10000);

fade out on anchor click and fade in href

I would like to know if it is possible to make fadings between two HTML-Documents.
I have a few HTML-Pages but let's make an example with two of them.
index.html, jobs.html
On both I have a menu with <a> buttons. What I want to do is:
I click on Jobs and index.html (which I am currently on) fades out and jobs.html fades in. Something like fading between divs but with a whole HTML document.
Any helps is much appreciated.
Hide the body using css.
Fade in the body
Click a button and grab its ID
Fade out the body
Navigate to the new url
<!DOCTYPE html>
<html>
<head>
<style>
body{
display: none;
}
.myBtn{
cursor: pointer;
}
</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script>
$(function(){
$('body').fadeIn();
$('.myBtn').click(function(){
url = $(this).attr('id') + '.html';
$('body').fadeOut(function(){
window.location = url;
});
});
});
</script>
</head>
<body>
<h1>index.html</h1>
<div class="myBtn" id="index">index</div>
<div class="myBtn" id="jobs">jobs</div>
</body>
</html>

PS. obviously the fiddle won't work, as you're trying to navigate to a new page, but you can still see the fade in at the beginning, and fade out when you click a button. Just need this script included for all pages to use.
Bottom line, this is not possible without some kind of pre-loading and interaction with a server side component
I would personally recommend PJAX. http://pjax.heroku.com/ It allows you not only catch an event and load a document based on the event, it updates the browser state, url, title, the back button works, etc.
example sites that use it to accomplish similiar behavior

*disclaimer, I did the second one...
Create your anchor tag and set a javascript onclick event. Call your fadeOut() function (which i've pasted below) You'll want it to fade out when you click, and when the next page loads, you'll want it to fade in:
jsfiddle: http://jsfiddle.net/HmGap/3/
HTML:
<script type="text/javascript">
window.onload=function(){fadeIn('body')};
</script>
<div id="body">
Content <br /><br />
<a onClick="fadeOut('body')" style="cursor:pointer">Click Me to Fade Out</a>
</div>
Javascript:
//fadeEffects
var fade_in_from = 0;
var fade_out_from = 10;
function fadeIn(element){
var target = document.getElementById(element);
target.style.display = "block";
var newSetting = fade_in_from / 10;
target.style.opacity = newSetting;
// opacity ranges from 0 to 1
fade_in_from++;
if(fade_in_from == 10){
target.style.opacity = 1;
clearTimeout(loopTimer);
fade_in_from = 0;
return false;
}
var loopTimer = setTimeout('fadeIn(\''+element+'\')',100);
}
function fadeOut(element){
var target = document.getElementById(element);
var newSetting = fade_out_from / 10;
target.style.opacity = newSetting;
fade_out_from--;
if(fade_out_from == 0){
target.style.opacity = 0;
target.style.display = "none";
clearTimeout(loopTimer);
fade_out_from = 10;
return false;
}
var loopTimer = setTimeout('fadeOut(\''+element+'\')',100);
window.location.href = "link.html";
}
Yes, it's possible, you can append the html in DIV (like you know), or you can use iframes, to manager the fade of the iframe tag

Javascript Styling Link

First disclosure: I have a lot of scripts running on this particular page.
I have a div of text that I have on page load, now there is a specific link which is toggled to this text, based on clicking on the link. WHEN the page is loaded, I want just the link to be a certain color.
Here is what I have for the text so far... which is displaying on pageload:
<script>
window.onload=function showDiv() {
document.getElementById('d1').style.display = "block";
}
</script>
Now I need to have my link a specific color on page load, but that color must be able to change back to its CSS default when another link is clicked:
Innovative Design Methodology
Like I said, there are other scripts I have running on this page, hence you see in the link.
Just for fun, here's my other code (toggling text & highlighting code):
<script type="text/javascript">
var currentItem;
function unhide(divID) {
if (currentItem) {
currentItem.className = 'hidden';
currentItem = null;
}
var item = document.getElementById(divID);
if (item) {
item.className = 'unhidden';
currentItem = item;
}
}
</script>
<script type="text/javascript">
var currentLink = null;
function changeLinkColor(link){
if(currentLink!=null){
currentLink.style.color = link.style.color;
}
link.style.color = '#f5b331';
currentLink = link;
}
</script>
You could add a css class on the anchor tag initially (which has your custom styling) and remove it on click on any of the links.
Your HTML
<a id="link1" class='CustomColor'></a>
And your CSS
.CustomColor
{
color:red;
}
And On click of any link,
document.getElementById("link1").className =
document.getElementById("link1").className.replace('CustomColor','');

Visible Image buildup from top to bottom: is there a way to show in one stroke?

I am using javascript to periodically replace a .png picture, which ist viewed fullscreen as the only content of a site. No matter how I try, in Firefox, after being loaded (as seen via firebug), the new image is always drawn from top to bottom. This takes some seconds. Is there any way to prevent this and show the picture all at once?
This is my current javascript code:
function preloadScreenshotPeriodically(){
var new_screenshot = new Image();
new_screenshot.src = "screenshot.png?defeat_firefox_caching=" + counter;
new_screenshot.id = "screenshot";
counter = counter + 1;
new_screenshot.onload = function(){
loadScreenshot(new_screenshot);
setTimeout("preloadScreenshotPeriodically();", 5000);
};
}
function loadScreenshot(new_screenshot){
document.getElementById("screenshot").parentNode.replaceChild(new_screenshot, document.screenshot);
}
I also tried to use two images, one of them hidden. Then loading the picture in the hidden one and swapping them. Same results :/
In an other version, I fetched the image with Ajax and after loading is complete, changed the url of the img-tag. My hope was, that the browser would recognize the picture had already been loaded and fetch it from the browsercache rather than loading it. But this didn't happen and I ended up with two requests to the server for one picture and the same slow drawing of it as in my other trys.
edit:
Now I tried it like suggested in answer 1. While it works just fine if I switch the picture when I load the next one (I don't want this), trying to switch it as soon as it is loaded (what I want) results in a blank window (very short) and visible loading of the picture as described above.
this works:
<body>
<style type="text/css">
#loaderWin { display:block; height:1px; width:1px; overflow:hidden; }
</style>
<div id="imagewin"></div>
<div id="loaderWin"></div>
<script type="text/javascript">
var screenshotCount=0;
function showFirstImage() {
loadNextImage();
}
function showNewImage() {
loadNextImage();
}
function nextImageLoaded() {
// swapImage();
}
function loadNextImage() {
swapImage();
screenshotCount = screenshotCount +1;
var nextImage = "<img id='loaderWinImg' src='screenshot.png?x="+screenshotCount+"' onload='nextImageLoaded()' />";
document.getElementById('loaderWin').innerHTML = nextImage;
}
function swapImage() {
document.getElementById("loaderWinImg").onload = '';
var newimage=document.getElementById('loaderWin').innerHTML;
document.getElementById('imagewin').innerHTML = newimage;
}
var showImages = setInterval("showNewImage()",15000);
showFirstImage();
</script>
</div>
</body>
</html>
this doesn't work:
<body>
<style type="text/css">
#loaderWin { display:block; height:1px; width:1px; overflow:hidden; }
</style>
<div id="imagewin"></div>
<div id="loaderWin"></div>
<script type="text/javascript">
var screenshotCount=0;
function showFirstImage() {
loadNextImage();
}
function showNewImage() {
loadNextImage();
}
function nextImageLoaded() {
swapImage();
}
function loadNextImage() {
screenshotCount = screenshotCount +1;
var nextImage = "<img id='loaderWinImg' src='screenshot.png?x="+screenshotCount+"' onload='nextImageLoaded()' />";
document.getElementById('loaderWin').innerHTML = nextImage;
}
function swapImage() {
// loadNextImage();
document.getElementById("loaderWinImg").onload = '';
var newimage=document.getElementById('loaderWin').innerHTML;
document.getElementById('imagewin').innerHTML = newimage;
}
var showImages = setInterval("showNewImage()",15000);
showFirstImage();
</script>
</div>
</body>
</html>
The problem can be seen here (in firefox problem like described above, in chrome there are no pauses between pictureloads and there is a blank window in between picture changes): http://sabine-schneider.silbe.org:1666/test.html
And here, what Rob suggested in answer 1 without any changes (displays the picture fine in firefox, but not in chrome - there I get a blank window in between picture changes): http://sabine-schneider.silbe.org:1666/test0.html
sounds like the image is "progressive" ( interlaced) and the preload needs more time for it to complete download.
You can set a width and height to the image also for a more stable presentation
( poss )
using
?defeat_firefox_caching=" + counter;
means you never cache the image ( which has confused me about your question ) - remove that line( unless you need it for something you haven't mentioned)
update: Can you try ...
<style type="text/css">
#loaderWin { display:block; height:1px; width:1px; overflow:hidden; }
</style>
<div id="imagewin"></div>
<div id="loaderWin"></div>
<script type="text/javascript">
var screenshotCount=0;
function showNewImage() {
screenshotCount = screenshotCount +1;
var newimage=document.getElementById('loaderWin').innerHTML;
document.getElementById('imagewin').innerHTML = newimage;
var nextImage = "<img src='screenshot.png?defeat_firefox_caching="+screenshotCoun+"'/>";
document.getElementById('loaderWin').innerHTML = nextImage;
}
var showImages = setInterval("showNewImage()",5000);
</script>

Toggle Visibility (Automatically causing one div element to hide when another is rendered visible)

Essentially what I am trying to do is create a website that has all of its content on the home page but only has some of the content visible at any one time. The way I read to do this is through toggling visibility.
The problem I am having is that: Assume the home page, when you first visit the website is blank (the way I want it to be). Lets say you click on the "about us" link. All of a sudden the about us section becomes visible (the way I want it to be). Now the problem that I have come across is when I know lets say click on the "products" link, I want the "products" content to become visible and the "about us" content to become invisible again. (Essentially creating the illusion of opening a new page within the same page).
Here is the code I have come up with so far. I can make certain div elements visible and invisible (onclick) but I can't figure out how to make sure only one div element is visible at any one time.
<script type="text/javascript">
function toggleVisibility() {
document.getElementById("about").style.display = "";
if(document.getElementById("about").style.visibility == "hidden" ) {
document.getElementById("about").style.visibility = "visible";
}
else {
document.getElementById("about").style.visibility = "hidden";
}
}
</script>
<script type="text/javascript">
function toggleVisibility1() {
document.getElementById("products").style.display = "";
if(document.getElementById("products").style.visibility == "hidden" ) {
document.getElementById("products").style.visibility = "visible";
}
else {
document.getElementById("products").style.visibility = "hidden";
}
}
</script>
The links to make the JavaScript work looks like this:
< href="#" onclick="toggleVisibility();">About
< href="##" onclick="toggleVisibility1();"> Products
here is another, simple function
<script type="text/javascript">
function toggle_visibility(id) {
var e = document.getElementById(id);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
</script>
if you click here, #foo will change visibility
<div id="foo">blablabla</div>
Without jQuery, you would want to do something like this:
<style type="text/css">
.content {
display: none;
}
#about {
display: block;
}
</style>
<script type="text/javascript">
function toggleVisibility(selectedTab) {
// Get a list of your content divs
var content = document.getElementsByClassName('content');
// Loop through, hiding non-selected divs, and showing selected div
for(var i=0; i<content.length; i++) {
if(content[i].id == selectedTab) {
content[i].style.display = 'block';
} else {
content[i].style.display = 'none';
}
}
}
</script>
About
Products
<div id="about" class="content">About stuff here</div>
<div id="products" class="content">Product stuff here</div>
Example here: http://jsfiddle.net/frDLX/
jQuery makes this much easier, but if you are beginning with JavaScript, sometimes you want to see the programmatic code, so you can tell what is going on.
This is exactly what jquery makes easier. Take this very simple example of what you're trying to achieve:
<style type="text/css">
.section {
display: none;
}
</style>
<script type="text/javascript">
function toggleVisibility(newSection) {
$(".section").not("#" + newSection).hide();
$("#" + newSection).show();
}
</script>
About
Products
<div id="about" class="section">about section</div>
<div id="products" class="section">products section</div>
Simple solution is like this:
<script type="text/javascript">
function toggleVisibility(divid) {
if (divid="about"){
document.getElementById("about").style.visibility = "visible";
document.getElementById("products").style.visibility = "hidden";
}
else if (divid="products")
{
document.getElementById("products").style.visibility = "visible";
document.getElementById("about").style.visibility = "hidden";
}
}
</script>
< href="#" onclick="toggleVisibility('about');">About
< href="##" onclick="toggleVisibility1('products');"> Products
use CSS display: property
element disappear
document.getElementById("products").style.display = "none";
element appear and is displayed as block (default for div)
document.getElementById("products").style.display = "block";
I posted sample code here: jQuery: menus appear/disappear on click - V2
PS
Here you can find nice examples about differences between display and visibility: http://wiw.org/~frb/css-docs/display/display.html
