Question

我的项目中有多个bootstrap轮播，我想减少我的html元素，我删除了carousel-indicators，我添加了js.I想为carousel-control做同样的事情，但我的头脑肿胀我怎样才能调整我的代码

＆＃13;

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>");
    });
  });

myCarousel控件：

var myCarousels = $(".carousel");
myCarousels.each(function(index, element) {
  var myCarousel = $("#" + $(element).attr('id'));
  myCarousel.append('<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev"><span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span><span class="sr-only">Previous</span></a><a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next"><span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span><span class="sr-only">Next</span></a>');
  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>");
