Question

我需要有关“猫头鹰轮播”的数据属性的帮助。

正如您在我的示例中看到的那样，幻灯片1和3在每个项目上都有属性。正在工作的唯一事件是触发事件，但在幻灯片1（第一张幻灯片）的负载上不起作用。

谢谢。

Answer 1

有一个事件initialized.owl.carousel，该事件将在轮播初始化时触发。请注意，必须在猫头鹰旋转木马初始化之前附加initialize.owl.carousel和initialized.owl.carousel事件。

利用这些事件在初始加载时改变颜色，检查更新的小提琴。

var owl = $('.owl-carousel');

owl.on('initialized.owl.carousel', function(property){  
  var current = property.item.index;
    var src = $(property.target).find(".owl-item").eq(current).find(".item").attr('setBgClr');
    if($(property.target).find(".owl-item").eq(current).find(".item").is('[setBgClr]')) {
        $(".heroes-wrap").css("background-color", src);
    } else {
        $(".heroes-wrap").css("background-color", "white");
    }
});

$('.owl-carousel').owlCarousel({
    autoplay: true,
  loop: true,
  margin: 10,
  autoHeight: true,
  autoplayTimeout: 10000,
  smartSpeed: 800,
  nav: true,
  items: 1,

});

owl.on('changed.owl.carousel',function(property){
    var current = property.item.index;
    var src = $(property.target).find(".owl-item").eq(current).find(".item").attr('setBgClr');

    if($(property.target).find(".owl-item").eq(current).find(".item").is('[setBgClr]')) {
        $(".heroes-wrap").css("background-color", src);
    } else {
        $(".heroes-wrap").css("background-color", "white");
    }
    
});

body {font-family:Arial, Helvetica, sans-serif;}
.heroes-wrap {margin:2em; padding:1em;}
