Onmouse event not triggered

Question

Goodmorning,

ive a code that show an information box over a div with a background image and when the mouse is entering that div. The information box is higher so it is showing more text but when te mouse is leaving the div it must go smaller. but sometimes the mouse leave event is not working.

$(".extra-info-vak, .extra-info-text").on('mouseenter', function () {
    var _this = this;
    $(this).find('.triangle-up').stop(true).fadeOut({
        duration: 200,
        queue: false,
        complete: function () {
            $(_this).find('.triangle-up').stop(true);
            $(_this).find('.extra-info-text').stop(true).animate({
                height: '150px'
            }, {
                duration: 800,
                queue: false,
                easing: 'easeOutQuart'
            });
        }
    });
})
$(".extra-info-vak").on('mouseleave', function () {
    var _this = this;
    $(_this).find('.extra-info-text').animate({
        height: '60px'
    }, {
        duration: 800,
        queue: false,
        easing: 'easeOutBounce',
        complete: function () {
            $(_this).find('.extra-info-text');
            $(_this).find('.triangle-up').fadeIn({
                duration: 200,
                queue: false
            });
        }
    });

});

    $(_this).find('.extra-info-text').stop(true).animate({

            $(_this).find('.triangle-up').fadeOut({
                duration: 200,
                queue: false
            });
        }

},

function () {
    var _this = this;
    $(_this).find('.triangle-up').stop(true);
    $(_this).find('.extra-info-text').stop(true).animate({

Use the latest jQuery Hover method to avoid difficulties. Below is the high-level code that helps you.

$( ".extra-info-vak, .extra-info-text" ).hover(

   function() {
      // Mouseover Actions
   }, 
   function() {
     // Mouseout Actions
   }

);
