- 锚链接js的另一种写法
为啥会发现这种写法呢？因为发现原来同事写的锚点类用jq只能找到一个，index一直等于0，所以查阅解决方法
//xxx为同一类名；mao_1、mao_2、......为锚点
<script type='text/javascript'>
$(function(){
$('.xxx').each(function(i,item){
$(item).on('click',function(){
console.log(i)
let scrollH = $(`.mao_${i+1}`).offset().top;
$('html,body').animate({scrollTop:`${scrollH}`},400)
})
})
})
</script>
