Fire event on Bootstrap carousel slide issue
问题 I try to use this code to fire on an event upon carousel slide, but it fails to work for some reason. Any suggestions? var $carousel = $('#carousel-showcase'); $carousel.carousel(); $carousel.bind('slide', function(e) { setTimeout( function(){ var left = $carousel.find('.item.active.left'); var right = $carousel.find('.item.active.right'); if(left.length > 0) { $("#wrap").animate({ backgroundPositionX: '+=50%' },0); } else if(right.length > 0) { $("#wrap").animate({ backgroundPositionX: '-=50
