你应该设置popover
trigger
模式组件
manual
并定义
mouseenter
和
mouseleave
事件使popuver在悬停时保持活动状态,并应用隐藏延迟以防止突然消失。
我提供了一个工作示例。
$('[data-toggle="popover"]').popover({
trigger: "manual" ,
html: true,
placement: 'bottom',
content: function() {
return `
<p class="description">Dummy text</p>
<a href="/film">Link</a>`
}
})
.on("mouseenter", function () {
var _this = this;
$(this).popover("show");
$(".popover").on("mouseleave", function () {
$(_this).popover('hide');
});
}).on("mouseleave", function () {
var _this = this;
setTimeout(function () {
if (!$(".popover:hover").length) {
$(_this).popover("hide");
}
}, 300);
});
p.description{
font-size: 0.7rem;
color: black;
margin-bottom: 0;
}
.popover {
top: 20px !important;
}
div.popover-body{
padding-bottom: 5px;
padding-top: 5px;
}
h5{
font-size: 1rem;
color: white;
}
img.poster {
opacity: 1.0;
&:hover {
opacity: 0.5;
transition: all .2s ease-in-out;
}
}
