我在示例中有bootstrap轮播,因为你看到了我不想在html中添加指标我只想添加js来为每个轮播工作,我在互联网上找到了一个功能,它的工作非常好但是它的工作只是为了一个旋转木马
我有两个旋转木马#carousel-1,#carousel-2但我的功能工作只是为了#carousel-1.我知道如果我给同一个班级,我的问题将得到解决但旋转木马的ID和li.data-target指标必须相同.
如何carousel-indicators自动添加js以查看其指标？
var myCarousel = $("#carousel-1");
myCarousel.append("<ol class='carousel-indicators'></ol>");
var indicators = $(".carousel-indicators");
myCarousel.find(".carousel-inner").children(".item").each(function(index) {
(index === 0) ?
indicators.append("<li data-target='#carousel-1' data-slide-to='"+index+"' class='active'></li>") :
indicators.append("<li data-target='#carousel-1' data-slide-to='"+index+"'></li>");
});
$('.carousel').carousel();.carousel{
margin:20px;

</html>你可以通过这种方式使它变得动态.这个解决方案可以在任何数量的旋转木马上使用,无需任何更改:)
$(document).ready(function(){
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) {
console.log(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>");
});
});
});
