我需要帮助数据属性的猫头鹰-旋转木马。
正如您在我示例中所看到的，在幻灯片1和3中，每个项目都有属性。仅工作事件是触发器，但不在加载幻灯片1（第一张幻灯片）时工作。
提前谢谢你。

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');
//console.log('Image current is ' + src);

有一个事件initialized.owl.carousel，它将在轮播初始化时触发。请注意，在Owl旋转木马初始化之前，必须附加initialize.Owl.Carousel和initialize.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。
