I have a problem when trying achieve hover effect on mapped image. I have an image with mapped areas and on all of them I want to show a different image when hover.
You can see my work so far here:
http://mantasmilka.com/map/pries-smurta.html
The problem is when I hover over area it show the image, but when I move the cursor (not leaving the area) it starts flickering. It takes area space pixel by pixel.
I've tried working with Javascript and jQuery solutions:
Javascript:
mouseenter="document.getElementById('Vilnius').style.display = 'block';" mouseleave="document.getElementById('Vilnius').style.display = 'none';"
jQuery:
$('.hide').hide();
setTimeout(function(){
$("#area-kaunas").mouseenter(function(){
$('#Kaunas').show();
});
$("#area-kaunas").mouseleave(function(){
$('#Kaunas').hide();
});
}, 500);
Why not just use hover() inside of jQuery? I'm also unsure why you bind the events after a 500 millisecond timeout?
$('.hide').hide();
$("#area-kaunas").hover(function() {
$('#Kaunas').show();
}, function() {
$('#Kaunas').hide();
});
There is a css property called "pointer-event" which gives the value "none" to the img tags that overlap in the mapped image and works as you need it. This is the documentation https://developer.mozilla.org/en/docs/Web/CSS/pointer-events
The problem will always be the compatibility of browsers.

Earlier today I asked a question about my webpage being very 'jumpy'.
I've posted a test version of my webpage here: http://armandbakx.nl/
And a codepen can be viewed here: http://codepen.io/anon/pen/GpmQoY
$('img').on('click', show);
$('.overlay').on('click', hide);
function show(){
$('.scroll-container').eq($(this).parent().index()).addClass('show');
$('.content-container').addClass('no-scroll');
$('.overlay').addClass('opacity');
}
function hide() {
$('.scroll-container').removeClass('show');
$('.content-container').removeClass('no-scroll');
$('.overlay').removeClass('opacity');
}
The idea of the page is that you click on an image (in this case a red square), resulting in a hidden container showing, which can be scrolled through, containing more information and images about this image.
However, when you click one of the squares, and the container and overlay show, the other images (squares) move. It was suggested to me that in my show function I should try and keep track of the position my browser was in when this container opened. Then in my hide function, return the browser to that position.
Truth to be told, I am not good with JavaScript AT ALL, so I'm pretty much clueless as to how I should apply this. I'm having more issues with this webpage and I have to fix them fast, hence I'm asking again. Could anybody help me with this?
From what I can tell, your squares are moving around because of the .no-scroll class. If I remove it, everything appears to work correctly.
try this:
$('img').on('click', show);
$('.overlay').on('click', hide);
function show(){
$('.scroll-container').eq($(this).parent().index()).addClass('show');
$('.overlay').addClass('opacity');
}
function hide() {
$('.scroll-container').removeClass('show');
$('.overlay').removeClass('opacity');
}
In your show function, you can retrieve the scroll position before the Text is shown.
scrollHeight = $(document).scrollTop();
In your hide function, set the scroll position to the value you got previously.
$(document).scrollTop( scrollHeight );
I made a jsfiddle so you can reproduce the bug:

I implemented a carousel to display 3 images. There's a current image (the image being displayed) and the other two remain hidden until I click one of the lateral arrows, causing the next image to slide from the side overlaying the (now previous) current image.
I've been 2 hours trying to figure out why there are certain specific 'transitions' in which the animation doesn't seem to work. For example, when clicking the left arrow to pass from the first image to the second and from the second to the third the animation works fine, but when clicking it again, the transition from 3 to 1 doesn't perform the slide animation. When moving in the opposite direction (using the right arrow) only one transition is animated. I think the problem has to do with that if in the click event handler function, but couldn't spot what's causing it.
Any help would be greatly appreciated.
TIA
The underlying issue here is related to the z-order of the three images. Your slide animations are only showing up where the image being slid in is above the displayed image; the "broken" transitions are actually occurring, they're just obscured by the "higher" visible image.
You can fix this by explicitly setting the z-index of the new and current image. For example, on the right transition:
prevLandscape.zIndex(1);
currLandscape.zIndex(0);
If you do this, you'll also need to increase the z-index of the arrows so they're above the images.

The issue is with the hide method you just simply hide it add the slide transition for the hide method.
change this line currLandscape.hide(); to currLandscape.hide("slide");
there seemed to be a problem with the order of the images also. please try this code out. The code is reuse of the previous image arrow code. Just try it out.
$('.arrowRight').on('click',function(e) {
var currLandscape = $(this).siblings(".currImg");
var nextLandscape = currLandscape.nextAll(".hiddenImg").first();
var currDesc= $(".currDesc");
var nextDesc= currDesc.nextAll(".hiddenDesc").first();
if (nextLandscape.length == 0) {
nextLandscape = currLandscape.siblings('.hiddenImg').first();
}
if (nextDesc.length == 0) {
nextDesc= currDesc.siblings('.hiddenDesc').first();
}
nextLandscape.show("slide", { direction: "right" }, 400, function() {
currLandscape.hide("slide");
});
currDesc.fadeOut().removeClass('currDesc').addClass('hiddenDesc');
nextDesc.fadeIn().removeClass('hiddenDesc').addClass('currDesc');
currLandscape.removeClass('currImg').addClass('hiddenImg');
nextLandscape.removeClass('hiddenImg').addClass('currImg');
});
This is certainly going to be an easy one but I can't get my head around what I am doing wrong...
I am trying to do a hover effect on a UL that affects a link within one of the UL LI's.
My current code looks like this:
$("ul.punchlines").hover(function () {
$(this).find("li a.light-grey-gradient").animate({'width' : '60%','top':'-65px'});
});
$("ul.punchlines").mouseleave(function () {
$(this).find("li a.light-grey-gradient").animate({'width' : '30%','top':'0px'});
});
This technically works as it gives the effect that the base of the element to be scaled remains in place and scales up from the bottom however it does it in two stages, I am trying to get this effect to happen all in one motion so it is a seamless scale and move.
I can do this easily with basic CSS3 transitions but as it is not supported in IE9 I am trying to use jQuery to allow for maximum browser support.
Can anyone offer a little support firstly about how I get the animation to happen in one motion (not staggered) and secondly if this is the right approach? I am new to jquery and only just getting my hands dirty with it :-)
Please see JQuery hover api:
http://api.jquery.com/hover/
also make sure that your "li" have absolute position.
$("ul.punchlines").hover(function () {
$(this).find("li a.light-grey-gradient").animate({'width' : '60%','top':'-65px'});
}, function () {
$(this).find("li a.light-grey-gradient").animate({'width' : '30%','top':'0px'});
});
See the effect in the photos in the article here:
http://www.popsci.com/science/article/2012-11/and-after-images-show-hurricane-sandys-devastation
Does anyone have any idea how that's done? I suppose I could make two frames with adjustable width within a fixed frame, but what about the handle? And the way the frame line and handle brighten and enlarge when you mouse over? Hover event, to be sure, but what kind of hover event?
It is very simple. You have 2 DIVs with the 2 different images (as background-image in css) overlapping eachother (In e.g absolute positioning.) (Perhaps the "Before" picture above)
Then you have a slider and when dragged it decreases the overlapping DIV's width, making the underlaying DIV show!
This functionallity can be found in a jQuery plugin called "Before/After"
Link: jQuery BEFORE / AFTER
You could of course just write your own that isn't dependant on jQuery UI.
;(function($){
$.fn.slidingThingamajig = function () {
return this.each(function(){
var $this = $(this);
$this.find('.handle')
.css({cursor:'ew-resize'}) // Here's your fancy cursor with directional arrows
.on('mousedown', function(e) {
$this.addClass('resizable');
$this.parents().on('mousemove', function (e) {
$('.resizable').css({width:e.pageX - $('.resizable').offset().left});
}).on('mouseup', function(e) {
$('.resizable').removeClass('resizable');
});
e.preventDefault();
});
});
}
})(jQuery);
You would probably need to tweak this a little, but it's mostly all there.
What would be the best way to have a single image which when you hovered your mouse over it, it would cycle fade in/out into a series of other images (like 3 or 4) before returning back to the original? Also, it would stop fading/changing images and go back to the original image if you moved your mouse off of the image.
Any help is appreciated.
Thanks!
I would see about having the mouseover event (or hover if you are using an external library) of the object that you are wishing to switch tied to a window.setTimeout function. Make sure to store the timeout id so that you can cancel it if the user's mouse exits the window. The window.setTimeout would then scroll through the pictures.
Maybe something like this:
$(function(){
$("#test").hover(function(e) {
$.data("timeout", window.setTimeout(function() {
//Transition here
}));
}), function(e) {
window.clearTimeout($.data("timeout"));
//Put image back to normal
});
});
Hope this helps,
