我需要在更改猫头鹰旋转木马幻灯片时调用角度7 函数，我想为幻灯片设计一个自定义点。谁能帮助我。.

我在下面引用了文档

https://www.npmjs.com/package/ngx-owl-carousel

https://owlcarousel2.github.io/OwlCarousel2/docs/api-events.html

<owl-carousel #owlElement [options]="sliderOptions" [carouselClasses]="['owl-theme','sliding']"></owl-carousel>


@ViewChild('owlElement',{ static: false }) owlElement: OwlCarousel;

self = this;
sliderOptions = {
  items: 1,dots: true,nav: false,navText: ["<i class='fa fa-angle-left'></i>","<i class='fa fa-angle-right'></i>"],onChange: function () {
    console.log("change");
    self.changeCustomDots();
 }
};

ngOnInit() {}

changeCustomDots() {
  console.log("change custom dots styles here..");
}
