I made this a couple of months back, but now I'm going through and re-tuning it. It's an image at the bottom of the page that when clicked it brings you to the top using JavaScript.
I already have the HTML, CSS and JS finished. But I can't get the CSS to work properly. I want a little message ("Scroll To Top") to remain hidden until the is hovered over, where it will appear.
I tried making a presentation here with JSFiddle, but it doesn't seem to want to work. (http://jsfiddle.net/9jvuoxra/1/)
Additionally Today I decided I want the image to become a background-image of the , but I can't get the to work correctly with {display: block;}. I've gotten it to work on other files in the past, but it doesn't want to work.
<!-- Scroll to the top option -->
<script>
function scroll () {
window.scrollTo (0, 0);
};
</script>
<div id="scroll-to-top">
<a onclick="scroll ()">
<span>Scroll To Top</span>
<img src="img/scroll-to-top.png" alt="Scroll To Top" title="Return to top">
</a>
</div>
<style>
div#scroll-to-top {margin-left: auto; width: 42px; height: 42px;}
div#scroll-to-top a {color: #ffffff;}
div#scroll-to-top a span {visibility: hidden;}
div#scroll-to-top a:hover span {visibility: visibile;}
div#scroll-to-top span {position: absolute; margin: 10px 0px 0px 0px; width: 42px; font-size: 10px; text-align: center;}
div#scroll-to-top img {display: block; width: 42px; height: 42px;}
div#scroll-to-top img:hover {cursor: pointer;}
</style>
scroll(X, Y) is already a defined javascript function, which is now replaced by the identical function scrollTo(X, Y), so using scroll() might not work always (as it is not working on jsfiddle). Instead you could write <a onclick="window.scrollTo(0, 0)"> to make it work.
For hiding the span, you may use jQuery.
Make sure to remove the visibility: hidden attribute also.
$(document).ready(function() {
// hide the span
$('#scroll-to-top span').hide();
// bind the hover event (mouseenter) to show the span and
// next hover event (mouseleave) to hide again
$('#scroll-to-top').hover(function(){
$('#scroll-to-top span').show();
}, function() {
$('#scroll-to-top span').hide();
});
});

I'm a complete novice at javascript so this will probably be really easy for you.My website (http://www.pjsmusic.com) requires a div of 200px when the user scrolls 40px down the page to appear. I have added some javascript
$(document).scroll(function() {
$('#jerkBox').toggle($(this).scrollTop()> 40);
});
However, the div appears when the page loads even as the page isn't scrolled from the top at all. How could I make this div appear when the user scrolls 40px, and disappear when they scroll back up the page past 40px, but not appear on load? You'll see what I mean if you visitthe link. Thanks in advance!
JQuery .toggle() controls the display property of the element. You can set it as display: none on the css right from the start:
#jerkBox {
display: none;
}
$(document).scroll(function() {
$('#jerkBox').toggle($(this).scrollTop()> 40);
});
#jerkBox {
float: right;
width: 200px;
height: 200px;
background: red;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="jerkBox">
jerkBox div
</div>
<div style="height: 2000px">
</div>
You just have to hide #jerkBox by default. Either in the CSS style of the element, set it to display: none or hide it immediately on document ready in your script.
/* CSS */
#jerkBox {
display: none;
}
or
/* JavaScript */
$(document).ready(function() {
$('#jerkBox').hide();
}
I have several underlaying divs with hover effect. Sometimes I need to show modal dialog and all undelaying divs should be "disabled". This is done by placing semi-transparent high z-index div on top of them, but the problem is that hover effect on underlaying div stays until I move my mouse. Is there a way to "unhover" underlaying divs when overlaying semi-transparent div becomes visible?
Simplified exanple
HTML:
<div class="somediv"></div>
<div id="modal"></div>
CSS:
#modal {
z-index: 1000;
background:#000;
position:fixed;
top:0; left:0;
width:100%;
height:100%;
display: none;
opacity: 0.3;
}
.somediv {
position: absolute;
left: 20px;
top: 20px;
width: 100px;
height: 100px;
background-color: red;
}
.somediv:hover {
background-color: blue;
}
JS:
setTimeout(function(){
$("#modal").show();
}, 5000);
Hover over square and wait 5 seconds.
It should work: http://jsfiddle.net/rjLhj/
When you open a modal (in JS), just add a class to your .somediv ('.no-hover', for example). In CSS, change your .somediv:hover to .somediv:not(.no-hover):hover.
I don't know about compatibility... So, you should test :P
JS:
setTimeout(function(){
$("#modal").show();
$('.somediv').addClass('no-hover')
}, 2000);
CSS:
.somediv:not(.no-hover):hover {
background-color: blue;
}
Update:
http://caniuse.com/#feat=css-sel3
It works on IE9+, FF3.5+ and Safari3.1+... But you can use Attribute Selectors for reach the same result.
HTML:
<div class="somediv" data-nohover="0"></div>
<div id="modal"></div>
CSS:
.somediv[data-nohover="0"]:hover {
background-color: blue;
}
JS:
setTimeout(function(){
$("#modal").show();
$('.somediv').attr('data-nohover','1')
}, 2000);
Or better, add one class to your somediv ('hashover', for example), remove it on modal open and define your css like this:
.somediv.hashover:hover {...}
Unfortunately the browser wont pick up mouse events until the mouse is moved...
The best way to deal with this is to create a new class that overrides the hover behaviour and apply this at the same time as you show the modal.
The website i am currently working on has a pop out div with a map of locations on it, my problem is once the pop up div has been closed i then have to refresh the page to open the div again
It is running jquery - here is the code
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#view_map_of_stocklists_link').click(function() {
//$('#popupdiv').show('slow');
$("#popupdiv").css('visibility', 'visible');
$("#mappy").css('opacity', '1');
});
$('.closepopup').click(function() {
$('#popupdiv').hide('slow');
});
});
</script>
The styling
<style>
#popupdiv
{
position: absolute;
left: 50%;
top: 50%;
background-color: white;
z-index: 100;
height: 600px;
margin-top: -200px;
width: 960px;
margin-left: -500px;
padding: 20px;
}
#view_map_of_stocklists_link:hover {
cursor:pointer;
}
.closepopup {
margin-top: 60px;
border: 1px solid #ccc;
background-color: #000;
color: white;
cursor: pointer;
}
</style>
and then the HTML itself
<div id="popupdiv" style="visibility:hidden;">
<center>
<iframe style="opacity:0;" id="mappy" src="http://mapsengine.google.com/map/embed?mid=zNedxWZ7lai0.krRxVqZZmyns" width="900" height="500"></iframe>
<div class="closepopup" style="width:200px">Close</div>
</center>
</div>
<h2 class="bold skin-font-color1">Our Beloved Stockists</h2>
<h5 class="skin-font-color1 p-wrapper"><!-- client txt --> <div id="view_map_of_stocklists_link" class="skin-font-color4">
<h4>View map of stockists</h4>
</div>

You are setting 'visibility' to 'visible' instead of 'display' to 'block'.
When jQuery .hide() is called it ultimately saves the previous display value and sets it to display:none; So you should be doing something like:
$('#view_map_of_stocklists_link').click(function() {
$('#popupdiv').hide('slow');
});
Which I just realized you have commented out in your code. I wish I could leave a comment but I need more rep.
Edit:
Sorry for complaining in may previous answer.
I just tried uncommenting the existing code and removing the visibilty stuff and that works just fine in your site. Try it.
The way you're showing the popup map doesn't match the way you're hiding it.
You show it with:
$("#popupdiv").css('visibility', 'visible');
But you hide it with:
$('#popupdiv').hide('slow');
That fades it out but ultimately sets the CSS style display: none on the #popupdiv element.
When you try to show it again, it still has display: none on it. Setting the visibility doesn't affect the display style.
You need to make the hide and show match up. Either use the visibility style, or the display style, but use the same one for both hiding and showing (and jQuery's .show() method uses display).
For example, you might create the <div> with display: none instead of visibility: hidden, and then you can use jQuery's .show() and .hide() consistently.
I am trying to create a carousel, where clicking on any element will slide it leftwards, simultaneously sliding the right element into viewport. For that, I need to have the divs stacked side by side. I am trying it out as a float based layout (see Fiddle ).
Problem is that here clicking the red colored div slides it leftward alright, but not the green element leftwards. This is probably due to the fact that they are actually lying below another, as visible when the overflow: hidden is removed from #cont's style. How elese to stack them side by side so that sliding one leftward automatically slides the next one leftwards as well? (Creating the to-be-next element on the fly while clicking and animating it into viewport is a no-no, the element should be present in the DOM!)
I'd suggest you use a plugin, as there is more to this than you may realize. There are many plugins out there for this, here's a list to get you started: http://www.tripwiremagazine.com/2012/12/jquery-carousel.html
I modified your Javascript, HTML, and CSS to get you pointed in the right direction:
http://jsfiddle.net/nf5Dh/2/
You need a container contContent, positioned absolutely, and that container gets moved within the container div. You just float the elements in contContent to get them next to each other.
HTML:
<div id='cont'>
<div id="contContent">
<div id='i1'></div>
<div id='i2'></div>
<div id='i3'></div>
</div>
</div>
CSS:
#cont {
width: 50px;
padding-top: 10px;
background: blue;
height: 50px;
overflow: hidden;
position: relative;
}
#contContent {
height: 50px;
width: 150px;
position: absolute;
top: 0;
left: 0;
}
#contContent > div {
float: left;
display: inline-block;
height: 50px;
width: 50px;
}
#i1 { background: red; }
#i2 { background: green; }
#i3 { background: yellow; }
And the JS:
$("#contContent > div").click(function(){
$("#contContent").animate({left: "-=50px"},1000);
});
You'd probably be better off using an ul instead of all divs, this is at least more semantically correct, though not technically necessary.
<div id="carousel">
<ul id="carouselContent">
<li id="slide1"></li>
<li id="slide2"></li>
<li id="slide3"></li>
</ul>
</div>
This:
#cont {
white-space:nowrap;
overflow: hidden;
}
.pane { // or whatever the slide divs are called. get rid of the float.
float: none;
display: inline-block;
*zoom:1;
*display:inline;
}
You can use that carousel where you can generate javascript for the carousel http://caroufredsel.dev7studios.com/configuration-robot.php
I've used http://sorgalla.com/jcarousel/ for things like this in the past, that's based on postion: relative and left/right offsets. Probably easier than messing with floats.
You can try using a list item instead, and display them inline.
I am having trouble developing a jQuery 'object'. I would like div1 (Refer to image below) to be the background div with an image in (Using a background image). I would then like div 2 (Refer to image below) to overlay div 1, which I can do. However, as I have little experience with jQuery it's the next part I'm struggling with. I would like, when you hover on div 2, I use jQuery slideDown() / slideUp() to show and hide div 3 (Refer to image below). It also needs to not close as it slides up (as the cursor will no longer be on div 2). Only when you're no longer hovering over the whole object will it close. I hope this makes sense... I just don't know where to start. If any more info is needed please ask.
Something like this should do it I believe, or at least it gives you a starting ground to play around with, and improve further.
Markup
<div class="wrapper">
<div class="one"></div>
<div class="two"></div>
<div class="three"></div>
</div>
CSS
.wrapper {
float: left;
}
.one {
background-color: grey;
width: 100px;
height: 100px;
}
.two {
background-color: blue;
width: 100px;
height: 20px;

.three {
background-color: green;
width: 100px;
height: 100px;
display: none;

JavaScript
$(function () {
$(".two").mouseenter(function (){
$(".one, .three").slideToggle();
});
$(".wrapper").mouseleave(function (){
$(".one, .three").slideToggle();
