I have a div that has background:transparent, along with border. Underneath this div, I have more elements.
Currently, I'm able to click the underlying elements when I click outside of the overlay div. However, I'm unable to click the underlying elements when clicking directly on the overlay div.
I want to be able to click through this div so that I can click on the underlying elements.
Yes, you CAN do this.
Using pointer-events: none along with CSS conditional statements for IE11 (does not work in IE10 or below), you can get a cross browser compatible solution for this problem.
Using AlphaImageLoader, you can even put transparent .PNG/.GIFs in the overlay div and have clicks flow through to elements underneath.
CSS:
pointer-events: none;
background: url('your_transparent.png');
IE11 conditional:
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='your_transparent.png', sizingMethod='scale');
background: none !important;
Here is a basic example page with all the code.
Yes, you CAN force overlapping layers to pass through (ignore) click events.
PLUS you CAN have specific children excluded from this behavior...
You can do this, using pointer-events
pointer-events influences the reaction to click-, tap-, scroll- und hover events.
In a layer that should ignore / pass-through mentioned events you set
pointer-events: none;
Children of that unresponsive layer that need to react mouse / tap events again need:
pointer-events: auto;
That second part is very helpful if you work with multiple overlapping div layers (probably some parents being transparent), where you need to be able to click on child elements and only that child elements.
Example usage:
.parent {
pointer-events:none;
}
.child {
pointer-events:auto;
}
<div class="parent">
I'm unresponsive
I'm clickable again, wohoo !
</div>
Allowing the user to click through a div to the underlying element depends on the browser. All modern browsers, including Firefox, Chrome, Safari, and Opera, understand pointer-events:none.
For IE, it depends on the background. If the background is transparent, clickthrough works without you needing to do anything. On the other hand, for something like background:white; opacity:0; filter:Alpha(opacity=0);, IE needs manual event forwarding.
See a JSFiddle test and CanIUse pointer events.
I'm adding this answer because I didn’t see it here in full. I was able to do this using elementFromPoint. So basically:
attach a click to the div you want to be clicked through
hide it
determine what element the pointer is on
fire the click on the element there.
var range-selector= $("")
.css("position", "absolute").addClass("range-selector")
.appendTo("")
.click(function(e) {
_range-selector.hide();
$(document.elementFromPoint(e.clientX,e.clientY)).trigger("click");
});
In my case the overlaying div is absolutely positioned—I am not sure if this makes a difference. This works on IE8/9, Safari Chrome and Firefox at least.
Hide overlaying the element
Determine cursor coordinates
Get element on those coordinates
Trigger click on element
Show overlaying element again
$('#elementontop').click(e => {
$('#elementontop').hide();
$(document.elementFromPoint(e.clientX, e.clientY)).trigger("click");
$('#elementontop').show();
});
I needed to do this and decided to take this route:
$('.overlay').click(function(e){
var left = $(window).scrollLeft();
var top = $(window).scrollTop();
//hide the overlay for now so the document can find the underlying elements
$(this).css('display','none');
//use the current scroll position to deduct from the click position
$(document.elementFromPoint(e.pageX-left, e.pageY-top)).click();
//show the overlay again
$(this).css('display','block');
});
I currently work with canvas speech balloons. But because the balloon with the pointer is wrapped in a div, some links under it aren't click able anymore. I cant use extjs in this case.
See basic example for my speech balloon tutorial requires HTML5
So I decided to collect all link coordinates from inside the balloons in an array.
var clickarray=[];
function getcoo(thatdiv){
thatdiv.find(".link").each(function(){
var offset=$(this).offset();
clickarray.unshift([(offset.left),
(offset.top),
(offset.left+$(this).width()),
(offset.top+$(this).height()),
($(this).attr('name')),
1]);
});
}
I call this function on each (new) balloon. It grabs the coordinates of the left/top and right/down corners of a link.class - additionally the name attribute for what to do if someone clicks in that coordinates and I loved to set a 1 which means that it wasn't clicked jet. And unshift this array to the clickarray. You could use push too.
To work with that array:
$("body").click(function(event){
event.preventDefault();//if it is a a-tag
var x=event.pageX;
var y=event.pageY;
var job="";
for(var i in clickarray){
if(x>=clickarray[i][0] && x<=clickarray[i][2] && y>=clickarray[i][1] && y<=clickarray[i][3] && clickarray[i][5]==1){
job=clickarray[i][4];
clickarray[i][5]=0;//set to allready clicked
break;
}
}
if(job.length>0){
// --do some thing with the job --
}
});
This function proofs the coordinates of a body click event or whether it was already clicked and returns the name attribute. I think it is not necessary to go deeper, but you see it is not that complicate.
Hope in was enlish...
Another idea to try (situationally) would be to:
Put the content you want in a div;
Put the non-clicking overlay over the entire page with a z-index higher,
make another cropped copy of the original div
overlay and abs position the copy div in the same place as the original content you want to be clickable with an even higher z-index?
Any thoughts?
I think the event.stopPropagation(); should be mentioned here as well. Add this to the Click function of your button.
Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
Just wrap a tag around all the HTML extract, for example
<a href="/categories/1">
<img alt="test1" class="img-responsive" src="/assets/photo.jpg" />
<div class="caption bg-orange">
<h2>
test1
</h2>
</div>
</a>
in my example my caption class has hover effects, that with pointer-events:none; you just will lose
wrapping the content will keep your hover effects and you can click in all the picture, div included, regards!
An easier way would be to inline the transparent background image using Data URIs as follows:
.click-through {
pointer-events: none;
background: url(data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7);
}
I think that you can consider changing your markup. If I am not wrong, you'd like to put an invisible layer above the document and your invisible markup may be preceding your document image (is this correct?).
Instead, I propose that you put the invisible right after the document image but changing the position to absolute.
Notice that you need a parent element to have position: relative and then you will be able to use this idea. Otherwise your absolute layer will be placed just in the top left corner.
An absolute position element is positioned relative to the first parent
element that has a position other than static.
If no such element is found, the containing block is html
Hope this helps. See here for more information about CSS positioning.
You can place an AP overlay like...
#overlay {
position: absolute;
top: -79px;
left: -60px;
height: 80px;
width: 380px;
z-index: 2;
background: url(fake.gif);
}
<div id="overlay"></div>
just put it over where you dont want ie cliked. Works in all.
This is not a precise answer for the question but may help in finding a workaround for it.
I had an image I was hiding on page load and displaying when waiting on an AJAX call then hiding again however...
I found the only way to display my image when loading the page then make it disappear and be able to click things where the image was located before hiding it was to put the image into a DIV, make the size of the DIV 10x10 pixels or small enough to prevent it causing an issue then hiding the containing div. This allowed the image to overflow the div while visible and when the div was hidden, only the divs area was affected by inability to click objects beneath and not the whole size of the image the DIV contained and was displaying.
I tried all the methods to hide the image including CSS display=none/block, opacity=0, hiding the image with hidden=true. All of them resulted in my image being hidden but the area where it was displayed to act like there was a cover over the stuff underneath so clicks and so on wouldn't act on the underlying objects. Once the image was inside a tiny DIV and I hid the tiny DIV, the entire area occupied by the image was clear and only the tiny area under the DIV I hid was affected but as I made it small enough (10x10 pixels), the issue was fixed (sort of).
I found this to be a dirty workaround for what should be a simple issue but I was not able to find any way to hide the object in its native format without a container. My object was in the form of etc. If anyone has a better way, please let me know.
I couldn't always use pointer-events: none in my scenario, because I wanted both the overlay and the underlying element(s) to be clickable / selectable.
The DOM structure looked like this:
<div id="outerElement">
<div id="canvas-wrapper">
<canvas id="overlay"></canvas>
</div>
<!-- Omitted: element(s) behind canvas that should still be selectable -->
</div>
(The outerElement, canvas-wrapper and canvas elements have the same size.)
To make the elements behind the canvas act normally (e.g. selectable, editable), I used the following code:
canvasWrapper.style.pointerEvents = 'none';
outerElement.addEventListener('mousedown', event => {
const clickedOnElementInCanvas = yourCheck // TODO: check if the event *would* click a canvas element.
if (!clickedOnElementInCanvas) {
// if necessary, add logic to deselect your canvas elements ...
wrapper.style.pointerEvents = 'none';
return true;
}
// Check if we emitted the event ourselves (avoid endless loop)
if (event.isTrusted) {
// Manually forward element to the canvas
const mouseEvent = new MouseEvent(event.type, event);
canvas.dispatchEvent(mouseEvent);
mouseEvent.stopPropagation();
}
return true;
});
Some canvas objects also came with input fields, so I had to allow keyboard events, too.
To do this, I had to update the pointerEvents property based on whether a canvas input field was currently focused or not:
onCanvasModified(canvas, () => {
const inputFieldInCanvasActive = // TODO: Check if an input field of the canvas is active.
wrapper.style.pointerEvents = inputFieldInCanvasActive ? 'auto' : 'none';
});
it doesn't work that way. the work around is to manually check the coordinates of the mouse click against the area occupied by each element.
area occupied by an element can found found by 1. getting the location of the element with respect to the top left of the page, and 2. the width and the height. a library like jQuery makes this pretty simple, although it can be done in plain js. adding an event handler for mousemove on the document object will provide continuous updates of the mouse position from the top and left of the page. deciding if the mouse is over any given object consists of checking if the mouse position is between the left, right, top and bottom edges of an element.
Nope, you can't click ‘through’ an element. You can get the co-ordinates of the click and try to work out what element was underneath the clicked element, but this is really tedious for browsers that don't have document.elementFromPoint. Then you still have to emulate the default action of clicking, which isn't necessarily trivial depending on what elements you have under there.
Since you've got a fully-transparent window area, you'll probably be better off implementing it as separate border elements around the outside, leaving the centre area free of obstruction so you can really just click straight through.
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.
http://ashleydw.github.io/lightbox/
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 want to create an Image when the users hovers over a certain thing. I want some data on the image which I am creating dynamically through javascript. Attaching the image of what I need to do here,...
I want the Target Image to be dispayed on hover. Any idea how can I proceed with?
I guess you are looking for tooltip with image. Try these examples.

You can try using jQuery's "hover" method and capture the mouse position from the callback function's event parameter. Then append a new absolutely positioned div and style it with the top and left parameter positions you acquired from the mouse position. Add any info that you need to display on the popup and append it to the newly created div.
Do you have any existing code?
Also you can try the
:hover
http://www.w3schools.com/cssref/sel_hover.asp and
:after
http://www.w3schools.com/cssref/sel_after.asp
and the content attribute
function goes in javascript:
function showIt(imgsrc)
{
document.getElementById('imageshow').src=imgsrc;
document.getElementById('imageshow').style.display='block';
}
function hideIt()
{
document.getElementById('imageshow').style.display='none';
}
I was wondering what could be the easiest way to add animation to some tab navigation.
I'm developing a small documentation website, Documentation, and as you can see I have that small arrow that adds up to the tab when navigation.
Well, what I was thinking is what if I can do it like this : Sample ; I tried something, I added a span via JS and then on click event ( applied to the li elements ) trigger the arrow animation. The thing is that doing that I stopped the script which is responsible for making the tabs work as they do stop.
So is there another way to achieve something like that ? And what would be the logic ?
Simplest would be to add a narrow absolute position div inside st_slide_container and position to the right. Inside that new element add another element that is just large enough for your arrow icon and is position absolute.
Either use callback of tabs change( depends on what is available in plugin API) or add another click handler to a.st_tab.
In this event handler you can get the index of current tab and apply animation of position top to the small arrow element
EDIT: Example of click handler to get index which would be multiplier for the top animation
$('a.st_tab').click(function(){
alert($(this).parent().index())
})

I got this to display nicely. But,
How can I modify this plugin so that when someone clicks an object, it does the nice "re-ordering" effect as seen in: http://desandro.com/demo/masonry/docs/filtering.html#demo
And it moves the object "X" positions up or down the list?
Is it easy to modify this to do that?
From the moment that all elements has float:left; when the user click the button hide the element with specific classes, for example if he clicks grey, then will hide red and black. In jquery the above example would be like this:
$(document).ready(function(){
$("#grey-button").click(function(){
$(".red, .black").hide()
});
});
This will hide all elements with classes red and black, adding the css property display and value none.
This will make the browser don't "see" them, so the rest elements will be positioned in a different place, according the floats you have set for them.
