How to generalize this script for multiple popups on mouseover

How to generalize this script for multiple popups on mouseover - javascript

I have a script that works to switch between two popups that are triggered by an onmouseover event. One feature of this is that the popup persists until the next onmouseover event. I want to have many of these and so the popup to be hidden can not be 'hard coded' as in my script. Is there a way to store in a variable the id of the popup that needs to be undisplayed the next time the popup function is called?

hide.style.display="none"
}
</script>

.pop {
position: absolute;
display: none;
top: 50px;
left: 200px;
width: 300px;
}
</style>
</head>
<body>
<table><tr>
<td onmouseover="popup(pop1,pop2)">Show popup 1</td>
<td onmouseover="popup(pop2,pop1)">Show popup 2</td>

<div class="pop" id="pop1">This is popup 1</div>
<div class="pop" id="pop2">Popup 2 is here</div>
</body>

One way to generalize it is to use element index to show the associated popup. This will require that the popup elements (pop class elements) is contained by an element, in order to make both the popper and the popup element indexes mapped equally like two arrays of same length.
When showing a popup, the popup element is saved in a variable which will be used later when the mouse is on a different popper element.

<script type="text/javascript">
addEventListener("DOMContentLoaded", function() {
var lastPopup = null;
function showit(ev) {
var popups = document.getElementById("popups").children;
eleToShow = popups[ev.target.cellIndex];
if (lastPopup && (lastPopup !== eleToShow)) lastPopup.style.display = "none";
eleToShow.style.display = "block";
lastPopup = eleToShow;
}
var poppers = document.getElementById("poppers").cells, i;
for (i = 0; i < poppers.length; i++) {
poppers[i].addEventListener("mouseover", showit, false);
}
}, false);
</script>
<style type="text/css">
.pop {
position: absolute;
display: none;
top: 50px;
left: 200px;
width: 300px;
}
</style>
</head>
<body>
<table><tr id="poppers">
<td>Show popup 1</td>
<td>Show popup 2</td>
</tr></table>
<div id="popups">
<div class="pop">This is popup 1</div>
<div class="pop">Popup 2 is here</div>
</div>
</body>
</html>

I probably should have started with this, but my poppers will actually be rows, not cells. I tried what seemed like simple modifications of Jay's code to do it with rows. I changed it to index rows and then used rowIndex to find the popups, but I am missing something.

apply jquery filter to an created div?

Hey guys i was wondering if someone could help with some issues on my code.
Basically ive created 4 elements(divs) in an onclick event.From html i've also done so that same button dissapears
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<link rel="stylesheet" href="blackjack2.css">
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="blackjack1.js"></script>
</head>
<body>
<button class= "boton" id="start">Play</button>
<button class= "boton" id="hit">Hit</button>
<button class= "boton" id= "stand">Stand</button>
<script type="text/javascript">
var jugar = document.getElementById('start')
var mas = document.getElementById('hit')
var mantener = document.getElementById('stand')
var cuerpo= document.getElementsByTagName('body')[0]
var crear_cartas= function() {
var card= document.createElement('div');
var texto =document.createTextNode("CASINO");
card.setAttribute("class","cartas");
card.appendChild(texto);
cuerpo.appendChild(card);
}
jugar.onclick= function(){
crear_cartas()
crear_cartas()
crear_cartas()
crear_cartas()
jugar.setAttribute('class','ocultar')
}
</script>
</body>
</html>
Up to there is ok , but im not sure if from jquery i can apply a filter that activates on the same onclick event that appears in javascript code (on those 4 created elements )to the even ones so that they make an animation lowering slightly the margin.
I've read about it but i am a bit at sea given that the filter would apply to created elements..
Thank you in advance guys
css class ".cartas" code included:
.cartas{
/*display: none;*/
margin: 260px 75px 0 75px;
display: inline-block;
border-radius: 10px;
border: 1px solid black;
padding-top: 50px;
height:100px;
width:100px;
color: #003366;
font-family: Muli,Helvetica Neue,Helvetica,sans-serif;
text-align: center;
background-color: #f0f8ff;
}

Add an onlcick event to all event divs. This event will add a class that will push the elements below those divs downward using a margin-bottom
Snippet below
var counter = 0;
var jugar = document.getElementById('start')
var mas = document.getElementById('hit')
var mantener = document.getElementById('stand')
var cuerpo = document.getElementsByTagName('body')[0]
var crear_cartas = function() {
card = document.createElement('div');
var texto = document.createTextNode("CASINO");
card.setAttribute("class", "cartas");
card.appendChild(texto);
cuerpo.appendChild(card);
}
jugar.onclick = function() {
for (var x = 0; x < 4; ++x) {
crear_cartas();
if ((x + 1) % 2 == 0) {
card.addEventListener('click', function() {
this.classList.add("move");
})
}
}
jugar.setAttribute('class', 'ocultar')
} //end func
div {
transition: margin-bottom 0.5s;
}
.move {
margin-bottom: 50px;
}

How can i adjust an iframe after a button press?

I'm trying to adjust the iframe after a press of a button. The problem is when you press the button and look for a flight (for example from Madrid to Barcelona) and it shows you the flights, a second scrollbar appears (main page scrollbar and the iframe scrollbar). How can I adjust the height of the iframe depending on the search results to use the main scrollbar? The code is here:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

}
body {

margin: 0px;
padding: 0px;
}
</style>
</head>
<body>
<iframe src='http://www.dohop.com/widget/2/?forms=flights&target=&tabs=top&orientation=horizontal&border_color=808080&text_color=202020&background_color=D0D0D0&form_border_color=808080&form_text_color=000&form_background_color=FAFAFA&width=1000&flang=es&whitelabel=http://vuelos.gangatravel.es/' scrolling='yes' width='1000' height='250' frameborder='0' style='border:none; overflow: hidden;' allowtransparency='true'>
</iframe>
<div style='text-align: right; width: 1000px; display:block; margin-top:5px;'>

</div>
</body>
</html>
Thanks!!

<div id='iframe_holder' style="overflow:hidden" >
<iframe style="width:100%;height:100%"></iframe>
</div>
you control the div dimension and position from js and the iframe will adapt its scroll bars.
or
var ifr_document = document.getElementById("iframe_id").contentWindow.document;
var target = ifr_document.getElementById("element_to_control");

Displaying text when link is clicked

This is inside my CSS:
div.hide {
display:none;
}
div.show {
color: #66CCFF;
}
This is in my HTML:
16:10
<script language="JavaScript">
function showText(show,hide)
{
document.getElementById(show).className = "show";
document.getElementById(hide).className = "hide";
}
</script>
<a name="16:10" onclick="showText('text1')" href="javascript:void(0);"></a>
<div id="text1" class="hide">This is your monitors aspect ratio.</div>
I'm trying to make the first link display the "This is your monitors aspect ratio." text lower on the page.
Any help is much appreciated.

Pure CSS Answer
Ok, if you just want to append text after you have moved to a position in a page using an anchor tag, you could do it with nothing but CSS similar to the following:
a:target:after{
content: " Test";
background-color: #ccffcc;
}
What this does is appends the text "Test" after the active anchor and colors. Here is an example page with implementation:
<!DOCTYPE html>
<html>
<head>
<title>Link Printer 2</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width">
<style>
a:target:after{
content: " Test";
background-color: #ccffcc;
}
.bigSection{
height: 200px;
}
</style>
</head>
<body>
<div class="bigSection">
<div><a name="first">First</a></div>
<div>To First</div>
<div>To Second</div>
<div>To Third</div>
</div>
<div class="bigSection">
<div><a name="second">Second</a></div>
<div>To First</div>
<div>To Second</div>
<div>To Third</div>
</div>
<div class="bigSection">
<div><a name="third">Third</a></div>
<div>To First</div>
<div>To Second</div>
<div>To Third</div>
</div>
</body>
</html>
Answer using JavaScript
You need to bind an eventListener and prevent it from moving to the next page. Here is a way to do it with JavaScript or CSS. The JavaScript way will actually set the text to whatever you want. The CSS way will hide actually hide the element.
<!DOCTYPE html>
<html>
<head>
<title>Link Printer</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width">
<style>
.hide{
display: none;
}
</style>
<script>
function jsShowText(event) {
var divToManip = document.getElementById("text");
if (divToManip.innerHTML === "") {
divToManip.innerHTML = "Hello";
}
else {
divToManip.innerHTML = "";
}
event.preventDefault();
}
function cssShowText(event) {
var divToManip = document.getElementById("text");
if (divToManip.className === "") {
divToManip.className = "hide";
}
else {
divToManip.className = "";
}
event.preventDefault();
}
function setListeners() {
document.getElementById("jsPrinter").addEventListener("click", jsShowText, false);
document.getElementById("cssPrinter").addEventListener("click", cssShowText, false);
}
window.onload = setListeners;
</script>
</head>
<body>
<div><a id="jsPrinter" href="" onclick="showText();">Click With JavaScript</a></div>
<div><a id="cssPrinter" href="" onclick="showText();">Click With CSS</a></div>
<div id="text">I'm text</div>
</body>
</html>

"showText" must receive an id parameter to be used with the call to "document.getElementById"
Try this, just 1 link that will display the text below after click:
<a name="16:10" onclick="showText('text1')" href="javascript:void(0);">16:10</a>
<script language="JavaScript">
function showText(id)
{
document.getElementById(id).style.display = "block";
}
</script>
<div id="text1" style="display:none;">This is your monitors aspect ratio.</div>
I'm just using style display to hide/show the element. Hope it helps.

just change your css like this:
div.show {
display:block;
color: #66CCFF;
}

Here I am going to provide an example with something that I was working, thank you Alberto Montellano for the example, that gave me an idea, however what was required at the end was something a little different, with the option not to show the data and display it only when I click and make it disappear when click again. In this example I am going to give you two options; you can have a button or a link to trigger the JS function to display and hide the body text, you can choose if you want the button or link that is way I put a comment (optional), both behave as the same, it is up to you which one you want to use.
<!DOCTYPE html>
<html>
<head>
<!-- CSS -->
<style>
#myDIV {
width: 100%;
padding: 50px 0;
text-align: center;
background-color: lightblue;
margin-top:20px;
}
</style>
</head>
<body>
<!-- text before the button or link -->
<p>Click the "PIN" button (or link) to display PIN options:</p>
<!-- The Pin button (optional) -->
<button type="button" onclick="myFunction()">PIN button:</button>
<!-- The Pin link (optional) -->
</br></br></br>
<a onclick="myFunction()" href="javascript:void(0);">PIN link:</a>
<!--Data will display or hide (toggle)-->
<div id="myDIV"style="display:none;">
These are the steps to get your PIN number: Bla bla bla.
</div>
<p><b>Note:</b> The text display when you click the button or link will take space, if you click again will be toggle.</p>
<!-- JS -->
<script>
function myFunction() {
var x = document.getElementById('myDIV');
if (x.style.display === 'none') {
x.style.display = 'block';
} else {
x.style.display = 'none';
}
}
</script>
</body>
</html>

Javascript changing background color

I tried to change a background color with javascript and it didn't work out, and after lots of trying I didn't find any problem.
var x=1;
switch(x) {
case 1: {
document.getElementsByClassName("gallery").style.backgroundColor="blue";
}
}
I don't see any need to copy html or css to here. If this code is fine though I'll edit and add the other codes.
Edit: Html added, as you requested.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>פרדס מרים ומרדכי</title>
<link href="../../CSS.css" rel="stylesheet" type="text/css" />
<script language="JavaScript" src="Album1.js" type="text/javascript"></script>
</head>
<body>
<div id="wrapper">
<div id="header"></div>
<div id="menu">
<pre class="menu1"><a class="menu1" href="../../index.html">דף הבית</a> <a class="menu1" href="../../HowToArrive.html">כיצד מגיעים</a> <a class="menu1" href="../../HowItAllBegan.html">איך הכל התחיל</a> <a class="menu1" href="../../Albums.html">אלבומי תמונות</a> <a class="menu1" href="../../Contact.html">צור קשר</a></pre>
</div>
<div id="main">
<div class="gallery_bg">
<div class="gallery"></div>
</div>
</div>
</div>
</body>
</html>
Edit: CSS added. I believe you only need the part referring to the gallery class. The whole code is really long, if you need it I'll add it too, just say.
.gallery {
width:550px;
height:550px;
-webkit-background-size: 550px 550px;
-moz-background-size: 550px 550px;
background-size: 550px 550px;
border:#fff 3px solid;
margin:0 auto;
}

Try this:
document.getElementsByClassName("gallery") returns NodeList , and it is like Array , so you can do:
document.getElementsByClassName("gallery")[0].style.backgroundColor="blue";
Or do it in loop:
var galleries = document.getElementsByClassName("gallery");
var len = galleries.length;
for(var i=0 ; i<len; i++){
galleries[i].style.backgroundColor="blue";
}

"document.getElementsByClassName" work like an array if you want to change the backgrouond color you have to use loop to change the color.
Solution:
const ulList = document.getElementsByClassName("list-item");
for(var i = 0; i < liList.length; i++){
ulList[i].style.backgroundColor = 'red';
}

Javascript doesn't change document?

Take a look at this example code, which doesn't work:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript">
<!--
function moveMe() {
document.getElementById('moveme').top = 200;
document.getElementById('moveme').style.backgroundcolor = 'green';
document.getElementById('writeme').innerHtml = 'abc';
alert('called!');
}
// -->
</script>
<style type="text/css">
.moveable {
position: absolute;
top: 30px;
left: 200px;
width: 100px;
height: 100px;
background-color: yellow;
}
#writeme {
background-color: red;
color: white;
}
</style>
</head>
<body>
<div id="moveme" class="moveable" onClick="moveMe()">
<p id="writeme">Hello!</p>
</div>
</body>
</html>
When I click on the text the alert is displayed, but nothing is changed in the document. The paragraph text is not overwritten, the div is not moved... tested it in FF and IE, also checked the DOM via Firebug: strange thing is that the new values are written to the nodes, but they are displayed in bold, and the old values are still there. WTF?
I guess I'm missing something fundamental here.

Non-zero lengths require units, "200" is missing its unit
JavaScript is case sensitive: backgroundColor and innerHTML
Since you appear to be using XHTML, your script is commented out

document.getElementById('moveme').top = 200;
needs to be
document.getElementById('moveme').style.top = "200px";
I think; and
document.getElementById('writeme').innerHtml = 'abc';
needs to become
document.getElementById('writeme').innerHTML = 'abc';
and it's backgroundColor with a capital C as #David spotted first.

Try this:
<script type="text/javascript">
function moveMe() {
document.getElementById('moveme').style.top = '200px';
document.getElementById('moveme').style.backgroundColor = 'green';
document.getElementById('writeme').innerHTML = 'abc';
alert('called!');
}
window.onload = moveMe;
</script>

Additionally to what the others said: Drop the <?xml version='1.0' encoding='UTF-8' ?>
, because that puts IE in Quirksmode.
