If you goto www.rambocats.com, as the page loads you'll see this bottom-center div showing up for a second or two, then disappears. (Div says "Gallery II" in pink letters). It's supposed to only appear once you've scrolled down to about 2/3 of the page. How do I prevent it from showing during initial load?
Here's the jQuery:
$(document).ready(function(){
var open = false;
$('#homiesSlideButton').click(function() {
if(open === false) {
$('#homiesSlideContent').animate({ height:'610px' });
$(this).css('backgroundPosition', 'bottom left');
$("#homies-wrapper img").peTransitionHilight({ // image highlight/transitions plugin
slideshow:true,
transition:"all",
duration:1500,
delay:4444, boost:0.3
});
open = true;
} else {
$('#homiesSlideContent').animate({ height: '0px' });
$(this).css('backgroundPosition', 'top left');
open = false;
}
});
});
$("#homiesSlideButton").hide();
$(window).scroll(function(){
if($(window).scrollTop()>4444){ // position on page when button appears
$("#homiesSlideButton").fadeIn();
}else{
$("#homiesSlideButton").fadeOut();
}
});
$(window).scroll(function(){
if($(window).scrollTop()>4444){ // position on page when button disappears
$("#homiesSlideContent").fadeIn();
}else{
$("#homiesSlideContent").fadeOut();
}
});
What's happening is that it's set to be visible by default, so it shows before the javascript/jquery runs to hide it.
What I tend to do for items that should not be visible from the start is add a CSS class to them that is set to display: none; or visibility: hidden;, like so:
.hide {
display: none;
}
then using jquery to remove the class after calling .hide(). on the element:
$('#elementId').hide().removeClass('hide');
It can be as simple as:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title>Let's hide and show a div</title>
<style type="text/css">
#myHiddenDiv { visibility: hidden; }
</style>
</head>
<body>
<div id="myHiddenDiv">
Hidden until after the script loads. It will be imperceptible in most cases. But if you comment out or remove the script, the div will indeed be hidden!
</div>
<script type="text/javascript">
document.getElementById('myHiddenDiv').style.visibility = 'visible';
</script>
</body>
</html>
I think it's animating the .hide() event, try style="display:none;" as part of the html for the $("#homiesSlideButton") element.
In the CSS for your div, set the div to have the property
visibility: hidden;
When the page has loaded,
$("#yourDivId").show();

I have a div that displays a little popup menu when clicked. I want users to be able to click anywhere in the body of the site to close the popup, but when I add code for that, the popup cant be opened at all anymore.
So I tried adding an if-statement so that the closemenu() function will only try close the popup if its already open, but it seems like the statement is evaluating to false even if the popup is open.
Here is the HTML for showing the popup:
<div class="popcolor" onclick="showmenu()"> Click!
<span class="popupcolor" id="myPopup">Pop!</span>
</div>
Here is the css:
.popcolor .show {
visibility: visible;
-webkit-animation: fadeIn 0.5s;
animation: fadeIn 0.5s;
}
Here is the Javascript:
function showmenu() {
var popup = document.getElementById("myPopup");
popup.classList.toggle("show");
}
function closemenu() {
var popup = document.getElementById("myPopup");
if (popup.style.visibility == "visible") {
popup.classList.toggle("close");
};
}
Here is the HTML for closing the popup:
<body onclick="closemenu()">
I've been through every post I can find on this for solutions, and I'm still stuck. Any help is appreciated.
You can use the getComputedStyle() method on the window object, to calculate the style rules that result from the classes applied to your popup element.
This gives you a reliable way of determining the values of different styling rules that result from, say, the 'close' class being applied to popup
Something along the lines of this should work for you:
function closemenu() {
var popup = document.getElementById("myPopup");
// Get the computed style, that is the combination of styles
// resulting from your CSS classlist, etc
var computedStyle = window.getComputedStyle(popup, null);
// Get visibility value from computed styles
var visiblityValue = computedStyle.getPropertyValue("visibility")
if (visiblityValue == "visible") {
popup.classList.toggle("show"); // Correct this from "close" to "show"
};
}
There are also some other functional issues with your implementation which are causing problems. Consider updating your showmenu() method to:
function showmenu(event) {
// Prevent event propagation, which would cause closemenu to call
// after this method is called
event.stopPropagation()
var popup = document.getElementById("myPopup");
popup.classList.toggle("show");
}
For more information on getComputedStyle(), see the MDN documentation
Problem here is that click event triggered from div bubbles up to body which eventually closes the popup.
function showmenu(e) {
e.stopPropagation();
console.log('toggle');
document.getElementById("myPopup").classList.toggle("close");
}
function closemenu(e) {
e.stopPropagation();
console.log('hide');
document.getElementById("myPopup").classList.add("close");
}
#myPopup.close {
visibility: hidden;
}
body {
border: 1px solid #ccc;
padding: 2rem;
}
<body onclick="closemenu(event)">
<div class="popcolor" onclick="showmenu(event)"> Click!
<span class="popupcolor close" id="myPopup">Pop!</span>
</div>
</body>
P.S. Use event.stopPropagation() to cancel/consume event
Because the visibility property is being set at the class level, the style information isn't available in the style property of your element. Maybe instead of checking for a specific style, you can check to see if the 'show' class is currently assigned to your element like so:
function closemenu() {
var popup = document.getElementById("myPopup");
if (popup.classList.contains("show")) {
popup.classList.toggle("close");
};
}
Problem in your code is with the use of JavaScript functions.
Try this simple example I took from W3Schools and enhanced it for your case.
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_add_class
There seems to be some issue with W3CSchool TryIt Editor page. Here is the link to JSBin for the same code: https://jsbin.com/xefolinape/edit?html,output
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.mystyle {
width: 100%;
padding: 25px;
background-color: coral;
color: white;
font-size: 25px;
box-sizing: border-box;
}
</style>
</head>
<body>
<p>Click the "Try it" button to add the "mystyle" class to the DIV element:</p>
<button onclick="myFunction()">Try it</button>
<button onclick="myFunctionClose()">Close it</button>
<script>
function myFunction() {
var element = document.getElementById("myDIV");
element.classList.add("mystyle");
}
function myFunctionClose() {
var element = document.getElementById("myDIV");
element.classList.remove("mystyle");
}
</script>
</body>
</html>
Hope this helps!
Say my html is this
<div class='screen'>
<p>*A lot of text here*</p>
</div>
<div class='screen'>
<p>*More text and some images here*</p>
</div>
<div class='screen'>
<p>*Even more text and an image here*</p>
</div>
and right below my html, I have this
<style>
.screens {
margin: 10px;
}
</style>
<script type='text/javascript'>
hide();
</script>
Now, the Javascript function hide is in an external JS file which I imported in the html file. This is the hide function.
function hide() {
$('.screen').hide();
}
Now, when I open up this page, sometimes it works (it hides the text right away so it is a blank page) and other times, the text shows for like one second and then the text becomes hidden. How come it doesn't hide the text right away 100% of the time? would it work 100% of the time if I do
<script type='text/javascript'>
$(document).ready(function() {
hide();
});
</script>
?
Create a wrapper div and give it a display:none;. When needed, display it with show()
CSS:
.wrapper{ display:none;}
HTML:
<div class="wrapper>YOUR CONTENT</div>
Javascript
$(document).ready(function(){
$(".wrapper").show();
});
Or if you just care about .screen, change its CSS to display:none and the javascript to show() instead of hide()
<style>
.screens {
margin: 10px;
display:none;
}
</style>
<script type='text/javascript'>
show();
function show() {
$('.screen').show();
}
</script>
I have created a customized menu. See here. On click of this link I have a shadowbox popping up which has a long list of items. Now I want to have a "back to top" anchor link which takes me back to the top of the menu list.
I've set your lightbox with the #box id.
Html
<div id="box">
...
<!-- long content there -->
To Top
</div>
CSS (setting the width of elements)
#box {
position:relative;
width:200px;
height:250px;
overflow:auto;
}
#box #toTop {
position:absolute;
display:none;
left:150px;
top:10px;
}
jQuery
$('#box').bind('scroll', function(e) {
if ($(this).scrollTop() > 100) {
$('#toTop').fadeIn();
$('#toTop').css({'top' : $(this).scrollTop() + 100});
} else {
$('#toTop').fadeOut();
}
});
$(document).on('click', '#toTop', function(e) {
e.preventDefault();
//$('#box').scrollTop(0); //just go to top
$('#box').animate({scrollTop : 0},'slow'); //animate
});
Fiddle
Pretty easy with:
document.querySelector("iframe").contentWindow.scrollTo(0,0);
Now put a button on the page and call that on click. Oh, and omit the height:100% on your body of the iframe, this way you get rid of the second scrollbar.
You can try this out by just pasting the line above and executing it in the console of your browser with your webpage.
To change selector so it only show/hides when i click the image i put spoiler/ popdown menu directly after .OS image. Right now the popdown is a child of the .OS container, so clicks on it are passed to the .OS click handler.
But the code isn't perfect because when i click the 1st MAC both spoilers are opened.
But I want that spoilers are opened one at a time
But the main problem is that I can't fix the javascript code properly inside these types of spoilers (dokuwiki class) inside <td> tags:
This is the javascript code I use :
<div class="dokuwiki">
<div class="right_page">
<div class="entry-content">
<script type="text/javascript" src="./zzzz_files/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".nonjs").removeAttr( "href"); //href is needed for users without JS
$('.OS').click(function(){
if($(".details").is(":visible"))
{
$(".details").not(":hidden").hide("slow");
return true;
}
else
{
$(".OS").not(this).each(function(i) {
$(".details").hide("slow");
});
$(".details").show("slow");
return false;
}
});
});
</script>
<style type="text/css">
<!--
.details {
display: none;
clear: both;
padding: 2px;
}
.nonjs{
cursor:pointer;
}
img {
border: 0px;
}
-->
</style>
I thought about doing a video to better explain the problem and provide the local version of files for testing code:
Thanks in advance
This code works:
$(document).ready(function(){
$(".nonjs").removeAttr( "href");
//href is needed for users without JS
$('.OS').click(function(e){
if(!$(e.target).parents('.details').length){
if($(this).find('.details').is(":visible"))
{
$(this).find('.details').not(":hidden").hide("slow");
return true;
}
else
{
$(this).find('.details').show("slow");
return false;
}
}
});
});
I don't know what you're asking but here is what I think you want:
When clicking on an image, show the details below it and hide all others. If the details are already visible, hide them. Clicking something inside the details should not affect anything.
Demo
$(document).ready(function(){
$(".nonjs").removeAttr( "href"); //href is needed for users without JS
$('.OS').click(function(){
var details = $(this).next(".details");
$(".details").hide("slow");
if(details.is(":hidden")) {
details.show("slow");
}
});
});
I haven't been able to find the answer to this anywhere.
How do you make a hidden div appear when mousing over where it would have been?
Please do not tell me how to make a link, I know how to make a link ;)
I have tried:
a.) onmouseover set visibility to visible and onmouseout set visibility to hidden
this works in 0 browsers
b.) setting borders to 0px and background transparent and innerhtml to "" onmouseout and reverting onmouseover
this works in chrome
c.) This was the most popular answer on the internet, which i knew wouldn't work, but I tried anyway: make a container div set to visible and then do visibility visible and visibility hidden for the inner div
d.) Setting opacity to 1/100 and 0
works in chrome
e.) last resort: i tried making a transparent gif and having it display onmouseout
this also failed
I haven't tried jquery's .hover but I have read that it may not work correctly.
I have no other ideas. Will somebody help, please?
If I get it right you want div element to show if you are over it and hide when the mouse is not over. If that's it you can do it only with html and css:
<head>
<style>
#outerDiv{width:100px;height:100px;background-color:blue;}
#innerDiv{width:100px;height:100px;background-color:red;display:none;}
#outerDiv:hover #innerDiv {display:block;}
</style>
</head>
<html>
<div id="outerDiv">
<div id="innerDiv">some text</div>
</div>
</html>
The outer div is always visible and when it's hovered the inner one is shown.
I think that this is going to help you: http://jsfiddle.net/eb4x9/
The mouseover event won't trigger when the div is hidden so you can detect it's position and size.
Here is the source:
HTML
<div id="foo"></div>
CSS
#foo {
width: 300px;
height: 300px;
background-color: red;
visibility: hidden;
}
JS
$(document).mousemove(function (event) {
var div = $('#foo'),
divLeft = div.offset().left,
divTop = div.offset().top,
divWidth = div.width(),
divHeight = div.height();
if ((event.pageX >= divLeft && event.pageX <= divLeft + divWidth) &&
(event.pageY >= divTop && event.pageY <= divTop + divHeight)) {
div.css('visibility', 'visible');
} else {
div.css('visibility', 'hidden');
}
});
$(document).mouseleave(function (event) {
var div = $('#foo');
div.css('visibility', 'hidden');
});
Best regards!
Try setting the display attribute of the div to 'block' along with the visibility attribute to 'visible' in your onmouseover event.
Set the display to 'none' and visibility to 'hidden' to hide.
Of course the trouble will be firing the mouse over on a hidden div.
This works in every browser I have ever used it in.
Try this, having two divs one empty and other with your content and toggling between them on mouseover
<html>
<head>
<script>
function toggle() {
var your_div = document.getElementById("your_div");
var empty_div = document.getElementById("empty_div");
if(your_div.style.display == "block") {
your_div.style.display = "none";
empty_div.style.display = "block";
}
else {
your_div.style.display = "block";
empty_div.style.display = "none";
}
}
</script>
<style>
#empty_div{width:100px; height:100px;}
#your_div{width:100px; height:100px; border: 1px solid #000fff;}
</style>
</head>
<body>
<div id="your_div" onmouseover="toggle()">xyz</div>
<div id="empty_div" onmouseover="toggle()"></div>
</body>
</html>
