Bootstrap popover: hide when cursor moves outside of the window - javascript

I want to display a popover which contains several buttons when user hovers over a text link
The problem I have is the default Bootstrap popover I'm currently using is dismissed when the cursor from the link which triggered it (e.g. when the user moves to select one of the buttons)
This jsFiddle is an example of what I tried to do.. The principle is: show popover when the link (#example) is hovered, hide popover when the popover (.popover) is unhovered.
But this doesn't work, although I'm sure that the BS popover is encapsulated in a .popover class (I check with FF dev debug tool).
Funny thing: it works with another div! If I replace
$('.popover').mouseleave(function(){
$('#example').popover('hide');
});
By this
$('.square').mouseleave(function(){
$('#example').popover('hide');
});
The popover is indeed hidden when no longer hovering the blue square.
Why doesn't work with .popover?

You need to hide popover when the mouse leaves the .popover-content not .popover. And .popover-content does not exist at the beginning so you need to bind the event to the document
$(document).on('mouseleave','.popover-content',function(){
$('#example').popover('hide');
});

Quickly scrolling away from hover-triggered popover does not hide popover

I am using hover-triggered popovers for certain highlighted rows in a table and when you scroll away from the element relatively quickly using the mouse scroll wheel, the popover continues to show for an extra second even though you are no longer hovering the target element. It creates a strange effect where the popover scrolls away from the direction you are scrolling to, moving outside the border of the table.
Here is some example code:
$('.popover_class').popover({
trigger: 'hover',
placement: 'right'
})
<tr class="bg-warning popover_class" data-toggle="popover" data-content="example"></tr>
I've tried a variety of solutions including hiding the popover on scroll event after initializing it with the code above:
$('.popover_class').on('scroll', function() {
this.popover('hide');
});
Using bootstrap 4, popper.js 1.15, jquery 3.4, DataTables.
Thanks
Set your popover animation to false (its true by default), which will stop applying a CSS fade transition to the popover.
$('.popover_class').popover({
trigger: 'hover',
placement: 'right',
animation: false
});
Triggering popover hide on mouse scroll as you've tried will not work, because the same animation effect will get triggered just the same.
I faced similar issue while displaying bootstrap popover in JQuery DataTable control.
As seen in the above snapshot, the popover message is displayed when the user clicks on the clipboard icon. The popover was hiding when user clicked anywhere else except the DataTable scrollbar. When the user scrolls the DataTable, the popover did not hide and was showing outside of the table.
In order to handle this scenario, I used the mouseleave event on the clipboard icon as shown below,
$(tableId).off('mouseleave', '.btn-clipboard').on('mouseleave', '.btn-clipboard', function (event: JQueryEventObject) {
if (event.currentTarget) {
let controlId = event.currentTarget.id;
$('#'+controlId).popover("hide");
}
});
So, when the mouse leaves the clipboard icon image, the popover will hide. I hope it helps / gives some idea.

Creating a preview effect for gallery images that closes when clicked outside

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..

After first click on delegate selector, it refreshes the page

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?

jQuery hover repositions on subsequent hovers

I have a hover event set on an element that use's jQuery UI's position function to show a div right underneath it, with the "out" set to hide that div.
The problem is, subsequent hovers position that div further and further on each hover.
Example: http://jsfiddle.net/Shpigford/8ZkgJ/
Hover over the red box, then hover over it again and you'll see the blue box quickly get positioned further and further to the right.
Same thing happens if I change to a click event. Seems like something odd is happening with positioning when I hide the div and then try to show it again.
Instead of position({...}).show(), use show().position({...}). The reason is that positon won't work when the element is invisible. You can find the following note at http://api.jqueryui.com/position/:
jQuery UI does not support positioning hidden elements

jQuery UI menubar, position submenu absolute left

I have created a jQuery UI navigation menu, using the menubar widget. It works how I expected except I would like it to behave slightly differently. As you can see here http://jsfiddle.net/hcharge/DebVr/ the submenu expands out and is positioned relative to the link that was clicked.
I would like it to expand out and stick to the left of the navigation bar, no matter which link was clicked, the submenu will always stay the same width. Like this image...
I've tried setting a position relative to the container and absolutely positioning the submenu, however I think that jQuery UI positioning is overriding this. Any advice would be great, cheers.
Edit: this needs to be done with JS as it has to be clicks and not hover actions that trigger the dropdowns
Why don't you do it all only with CSS?
See http://jsfiddle.net/DebVr/8/
Note: the background is blue in order to see the white borders.
Edit:
If you want some functionality, you can add it later, but I think that the basis should be with CSS.
See my code with some functionality here: http://jsfiddle.net/DebVr/11/
var links=$('#bar1>li>a').each(function(index,obj) {
obj.tabindex=index+1;
});
$('#bar1>li>a').focus(
function(){$(this).siblings('ul').show();}
);
$('#bar1>li>a').blur(
function(){$('#bar1>li>ul').hide();}
);
Edit 2:
If you want to hide again the submenu when clicked, use the following code:
var links=$('#bar1>li>a').each(function(index,obj) {
obj.tabIndex=index+1;
});
$('#bar1>li>a').focus(function(){
$(this).siblings('ul').addClass('show');
});
$('#bar1>li>a').mousedown(function(){
$(this).siblings('ul').toggleClass('show');
});
$('#bar1>li>a').blur(function(){
$(this).siblings('ul').removeClass('show');
});
And CSS:
#bar1>li>ul.show{
display:block;
}
See it here: http://jsfiddle.net/DebVr/16/
Edit 3:
In the code above, I replaced obj.tabindex with obj.tabIndex, and updated the jsfiddle.
The problem is that if you click on the submenu, the anchor loses focus and then the submenu dissapears. On Chrome it can be easily fixed setting the focus event to #bar1>li instead of #bar1>li>a, but then the event doesn't work on firefox... I'm working on a solution, but meanwhile you can use http://jsfiddle.net/DebVr/16/.
Edit 4:
Finally, the fixed code: http://jsfiddle.net/DebVr/18/
It works on Chrome, Firefox and IE.
