强调，虽然我花了时间在发布前寻找一种方式，我找到了解决办法右后:)

这样可以用安培绑定来实现，加功放绑定领导

<script async custom-element=\"amp-bind\" src=\"https://cdn.ampproject.org/v0/amp-bind-0.1.js\"></script>

旋转木马前添加此

<amp-state id="selected"><script type="application/json"> {"slide": 0} </script></amp-state>

和这对放大器传送带代码

on="slideChange:AMP.setState({selected: {slide: event.index}})"

加载类来按钮与活性类，如果选择

<div class="carousel-preview"> 
<button [class]="selected.slide == 0 ? 'active' : ''" class="active" on="tap:carousel-with-preview.goToSlide(index=0)">title1</button> 
<button [class]="selected.slide == 1 ? 'active' : ''" on="tap:carousel-with-preview.goToSlide(index=1)">title2</button> 
<button [class]="selected.slide == 2 ? 'active' : ''" on="tap:carousel-with-preview.goToSlide(index=2)">title3</button> 
<button [class]="selected.slide == 3 ? 'active' : ''" on="tap:carousel-with-preview.goToSlide(index=3)">title4</button> 
<button [class]="selected.slide == 4 ? 'active' : ''" on="tap:carousel-with-preview.goToSlide(index=4)">title5</button> 
</div>
