juqery：切换鼠标悬停进出

Posted 2021-02-25

this is the way for toggling something on mouse hover in and out

// HELL YA
$('.unit').hover(function (e) {
    var isIn = e.type === 'mouseenter',
          $this = $(this);
 
        $this.toggleClass('unit-hover',isIn);
        $this.find('.thumb a')
                .children('.thumb_BW').toggleClass('hidden',isIn)
            .end()
                . children('.thumb_C').toggleClass('hidden',!isIn);
 
        $this.children('.arrow-details').toggleClass('hidden',!isIn);
});
