我的项目中有多个引导轮播，我想减少我的 html 元素，我删除了我的carousel-indicators并使用 js 添加。我想为carousel-control做同样的事情，但我的头肿了，我该如何调整我的代码
var myCarousels = $(".carousel");
myCarousels.each(function( index, element ) {
var myCarousel = $("#"+$(element).attr('id'));
myCarousel.append("<ol class='carousel-indicators'></ol>");
var indicators = $("#"+$(element).attr('id') + " .carousel-indicators");
$("#"+$(element).attr('id') +" .carousel-inner").children(".item").each(function(index) {
(index === 0) ?
indicators.append("<li data-target='#"+$(element).attr('id')+"' data-slide-to='"+index+"' class='active'></li>") :
indicators.append("<li data-target='#"+$(element).attr('id')+"' data-slide-to='"+index+"'></li>");
});
