So I'm trying to make a simple lightbox on a concert listings page. You click a listing (.performer), and then an info box (.lightboxinfo) gets overlaid while a semi-opaque white div lightens the rest of the screen (#whitepage). Then, you click anywhere on the screen, and the box and white div disappear.
Everything works fine except the final z-index changes. The box and white div become fully transparent, but the z-index clearly haven't been changed since I can't click on any links.
Anyone know what I'm doing wrong? Thanks so much!
The javascript is below:
$('.performer a').click(
function(){
$('.lightboxinfo').css('z-index','110').animate({opacity:'1'}, {queue:false,duration:500});
$('#whitepage').css('z-index','100').animate({opacity:'0.4'}, {queue:false,duration:500});
});
$(document).click(
function(){
$('#whitepage').css('z-index','-100').animate({opacity:'0'},{queue:false,duration:100});
$('.lightboxinfo').css('z-index','-110').animate({opacity:'0'},{queue:false,duration:100});
});
});
Why mess around with the z-index when you can set 'display:none' after your opacity becomes 0?
// when appearing
$('#whitepage').css('opacity','0').show().animate({opacity:'0.4'}, 500);
// when disappearing
$('#whitepage').animate({opacity:'0'}, 100, function () {
$('#whitepage').hide();
});
Also, each time you click on the performer link, you're adding another event handler to the document. You may want to do that only once, outside of the click and only if the whitepage is visible.
$('.performer a').click(function () {
});
$(document).click(function () {
$('#whitepage:visible').animate(...
});
This is a bit difficult to answer as you haven't given the HTML and CSS, but there are a few things you should probably look at.
I assume your lightbox divs are positioned absolutely. Any (container) elements that you want to appear over them must be positioned relatively or absolutely or z-index will have no effect and relatively / absolutely positioned elements will always be on top of them.
You're animating the opacity manually, rather than using jQuery's built in fadeOut animation. Apart from giving compatibility with browsers that don't support opacity, fadeOut also sets the hidden element to display: none. This allows you to click on stuff that would otherwise be underneath the lightbox, whereas just reducing the opacity to 0 still leaves the element there and able to accept and block clicks. (So using fadeOut also means you'd no longer have to toggle the z-index.)
This is not directly related to the problem you mentioned, but both of the events you've set up will fire when you click on a .performer a link. (I think this is why you've prevented the animations from being queued: both will run together and the one that sets the opacity to 1 wins as it finishes last.) This does, however, stop the lightbox getting the z-index you want. To prevent this happening, you either need to set the close lightbox click event to #whitepage or stop the event propagating.
$('.performer a').click(function(event)
{
$('.lightboxinfo, #whitepage').fadeIn(500);
event.stopPropagation();
});

I am making a preview box that pops up when you click a gallery image and need to make it disappear when you click outside of it. I found many solutions but none work with my code. I think the problem is I may need a while loop but I tried several conditions and all were infinite.
This is the last solution I tried. The preview works but I can't get it to close when I click out.
DEMO
$('.portPic').click(function() {
if ($(this).attr('data-src2')) {
$('#clickedImg').attr('src', $(this).attr('data-src2'));
} else {
$('#clickedImg').attr('src', $(this).attr('src'));
}
$('#clickedImg').css('visibility', 'visible');
$('#clickedImg').blur(function() {
$('#clickedImg').css('visibility', 'hidden');
});
});
I've done a similar thing with a pop-out menu, where the user clicks "off" the menu and it closes. The same can be applied here.
I used an overlay div which spans the whole screen (with a translucent opacity - maybe 0.6 black or similar; or whatever colour you want) which gives a nice modal effect. Give it an id - let's say modal-overlay.
You can put it static in your page code, and set the display to none and make it the full-size of the page (through a CSS class).
<div id="modal-overlay" class="full-screen-overlay"></div>
Set the z-index of the overlay to higher than the rest of your page, and the z-index of your popup to higher than the overlay. Then when you show your popup, also set the visibility of the modal-overlay to visible, too.
In your script code, put an event handler for when the modal div is clicked:
$('#modal-overlay').click(function() {
$('#clickedImg').hide();
$('#modal-overlay').hide();
})
I would also use the .hide() jQuery method, which is easier than typing out the visibility.
Better still, if you have more than 1 thing going on (which you would with a modal overlay), wrap your "show/hide" of the popup in a hidePopup() or closePopup() method and call it onClick to save re-using code.
For effects when opening the popup/overlay, you can also use jQuery animations like .fadeIn() or .slideDown(). Use fadeOut and slideUp to hide.
These animations also perform the showing/hiding, so you wouldn't need to call .hide() or .show().
Check out this link to jQuery's API documentation for animations. Very useful and a good read.
Hope this helps!
You'll need to create a seperate div that is most likely fixed position that sits just one step lower (z-index) than your popped-up image. Attach a click handler to this div (overlay) and do your showing/hiding functions in there.
You can use modal photo gallery.

You can use this codepen code, too. SO is not letting me post the link here. So serach using thi "Bootstrap Gallery with Modal and Carousel".
Hope this helps..
I am having a serious problem using .delegate in jQuery 1.11
I have a sidebar called ".local-filters" which opens when I click #consult-filter.
After that, the hidden sidebar from the right appears (named .local-filter) (toggles a class called .active) and ".overlay" (100% height and width div) makes a black background with class ".active"
I used this to make that happen. Also, I want to click on .overlay (black background) and toggle the overlay class to make it visual disappear.
$(document).delegate('#consult-filter, .overlay, .cerrar filtros','click',function(){
$(".local-filters").toggleClass('active');
$("body").toggleClass('menu-active');
return false;
});
I read a lot of articles and read something about bubble spreading, but I don't know actually what is happening.
Everything is working correctly, but I don't know why in the second click I made to this element, it automatically refreshes the entire page.
Any ideas?
I have to do something like pexeso. When you hover element, it will flip front to back side (they have different texts) and when your mouse is out, it will fade from back to front side. This is example HTML, how it looks like:
<div class="pexeso">
<div class="pad">
<div class="front">1</div>
<div class="back">ONE</div>
</div>
etc...
There is some CSS, to look it well (it is in the jsFiddle source, attached bellow). Then Handling mouse enter and leave with jQuery:
$('.pexeso .pad').each(function() {
var el = $(this);
var back = el.find('.back');
el.on('mouseenter', function() {
back.removeAttr('style');
el.removeClass('before-fade').addClass('do-flip');
});
el.on('mouseleave', function() {
el.removeClass('do-flip').addClass('before-fade');
back.stop(true, true).fadeOut(250, function() {
el.removeClass('before-fade');
});
});
});
Here is full example in jsFiddle: DEMO
Try to hover any element from left or right side of your screen, it will works great. But now try to hover from top or bottom, it will do weird things to graphic and also, sometimes it stucks and remains invisible.
Probably know the problem: When you hover from top or bottom, it will start flipping, and when you are too slow, it also fires event mouseleave, because flipping is in progress and you are actually at empty space. Then it calls 1st function, then second, a lot of time and it got stuck. But I don't know how to fix it, can you help me?
Ok guys, don't try anymore, I already found a solution. Whoever is interested, how I fixed it, here is solution:
In CSS, make .back element always visible, so find this line &.do-flip { and add this style .back { display: block !important; }
In jQuery, there is no need to have back.removeAttr('style');, also this did mess with opacity style (fading effect)
Now wrap every "pad" with parent, for example .pad-container and give him exact sizes as .pads, now we will manipulate with him
Each function will take these wrappers, not "pads", so in jQuery $('.pexeso .pad-container').each(function() {...
Bind events mouseenter and mouseleave on this wrapper, but changing classes remain on "pads" and fadeOut effect on back element. Also, add function .show() to this back element before fadeOut.
That's all. Here is updated version: UPDATED DEMO
I am creating a hover over button, once hovered it will scroll up to unreal more content over my slideshow, but when I hover over the button it pulls up but wont come back down.
Click here to see live, hover over Contact Our Team Button on slider
jQuery(".buttontwo").hover(
function(e){
jQuery('.buttontwo').animate({top:'0px', bottom:'auto'}, 200)
},
function(e){
jQuery('.buttontwo').animate({bottom:'75px', top:'auto'}, 200)
}
);
Any ideas guys?
Thanks
Try adding a fixed value to the top property in the second function().
However you should be aware that as soon as you hover the button and the animation starts the second function will be triggered since you're not hovering the button anymore.
You might have to find a different way to animate that, perhaps adding aonMouseEnter / onMouseLeave event to the button's container.
I have a div that "drops down" thanks to jquery's slidetoggle and hover functions.
Inside that div I have some info (like the date, and a note counter) And I have three buttons.
Two of them are tumblr buttons ( {LikeButton}, {ReblogButton} )
and the third is an entypo symbol.
I have to float them all to the right in their own seperate class or they overlap (A problem of tumblr's, their like and reblog buttons are not well made)
I've identified that it is the "float:right" css bit that is making my jquery slidetoggle dropdown 'jumpy'.
(Or rather, it slides down, and in a millisecond slides up then down again, creating a jittery effect)
Does anyone know what might be causing this? Does anyone know a better way of lining up 3 spans on the right edge of a div (text-align:right doesn't work, I tried that already)

If it helps
Are you referring to the fact that when you mouse over it, it expands, then slightly retracts? If so try adding the min-height property set to the size of the icons to the .notes element and it seems to prevent this jittering.
Tip:
I noticed if you mouse out right away it will jitter too because it calls the method at the same time. Set a flag when the animation initiates to prevent the other animation from starting. something like this pseudo code:
//Global Flag
flag = false;
-- start function --
//prevent animation if another animation is in progress.
if(flag) return;
flag = true;
your.animation(function(){
//callback (when animation is done)
flag = false; //rest flag
});
The reason why it jitters is because since the elements inside are set to float, the height of the parent element is not affected, therefor the animation treats it as if it's empty. But setting a min-height or just height compensates for that. I'm sure it's more complicated than that but that's what's going on in a nutshell.
