在悬停时出现Bootstrap Popover / Disappear而不是Click

Question

I'm building a website with Bootstrap's Popover and I can't figure out how to make the popover appear on hover instead of click.

All I want to do is have a popover appear when someone hovers over a link instead of clicking on it and for the popover to disappear when they move away. The documentation says it's possible using either the data attribute or jquery. I'd much rather do it with jquery since I have multiple popovers.

Answer 1

Set the trigger option of the popover to hover instead of click , which is the default one.

This can be done using either data-* attributes in the markup:

<a id="popover" data-trigger="hover">Popover</a>

Or with an initialization option:

$("#popover").popover({ trigger: "hover" });

Here's a DEMO .

Answer 2

I'd like to add that for accessibility, I think you should add focus trigger :

ie $("#popover").popover({ trigger: "hover focus" });

Answer 3

If you want to hover the popover itself as well you have to use a manual trigger.

This is what i came up with:

function enableThumbPopover() {
    var counter;

    $('.thumbcontainer').popover({
        trigger: 'manual',
        animation: false,
        html: true,
        title: function () {
            return $(this).parent().find('.thumbPopover > .title').html();
        },
        content: function () {
            return $(this).parent().find('.thumbPopover > .body').html();
        },
        container: 'body',
        placement: 'auto'
    }).on("mouseenter",function () {
        var _this = this; // thumbcontainer

        console.log('thumbcontainer mouseenter')
        // clear the counter
        clearTimeout(counter);
        // Close all other Popovers
        $('.thumbcontainer').not(_this).popover('hide');

        // start new timeout to show popover
        counter = setTimeout(function(){
            if($(_this).is(':hover'))
            {
                $(_this).popover("show");
            }
            $(".popover").on("mouseleave", function () {
                $('.thumbcontainer').popover('hide');
            });
        }, 400);

    }).on("mouseleave", function () {
        var _this = this;

        setTimeout(function () {
            if (!$(".popover:hover").length) {
                if(!$(_this).is(':hover')) // change $(this) to $(_this) 
                {
                    $(_this).popover('hide');
                }
            }
        }, 200);
    });
}

The functionality, you described, can be easily achieved using the Bootstrap tooltip.

<button id="example1" data-toggle="tooltip">Tooltip on left</button>

Then call tooltip() function for the element.

$('#example1').tooltip();

After trying a few of these answers and finding they don't scale well with multiple links (for example the accepted answer requires a line of jquery for every link you have), I came across a way that requires minimal code to get working, and it also appears to work perfectly, at least on Chrome.

You add this line to activate it:

$('[data-toggle="popover"]').popover();

And these settings to your anchor links:

data-toggle="popover" data-trigger="hover"

See it in action here , I'm using the same imports as the accepted answer so it should work fine on older projects.
