Javascript jQuery增加div中的数字

我希望通过jQuery将div中的数字设置为increment+1

原始代码如下所示：

<div class="timeline">
<div class="timeline__item">
    <div class="timeline__item__icon-wrap">
         <div class="timeline__item__icon">
             1
         </div>
    </div>
    <div class="timeline__item__content padding-left">
         <div class="timeline__item__description">
              <h3>Day 1</h3>
             <p>t   t  t  t  t  t  t  t  t  t</p>
         </div>
    </div>
</div>
<div class="timeline__item">
     <div class="timeline__item__icon-wrap">
         <div class="timeline__item__icon">
             1
         </div>
     </div>
    <div class="timeline__item__content padding-left">
         <div class="timeline__item__description">
             <h3>Day 2</h3>
             <p>t   t  t  t  t  t  t  t  t  t</p>
         </div>
     </div>
 </div>
 <div class="timeline__item">
     <div class="timeline__item__icon-wrap">
         <div class="timeline__item__icon">
              1
         </div>
     </div>
     <div class="timeline__item__content padding-left">
         <div class="timeline__item__description">
             <h3>Day 3</h3>
             <p>t   t  t  t  t  t  t  t  t  t</p>
         </div>
     </div>
 </div>  

$（'.timeline\uuuu item\uuuu icon'）。每个（（i，e）=>$（e.text（i+1））

您试图解决此问题的位置。还有，你为什么不把正确的数字放进去呢？
jQuery( document ).ready(function() {
var number = 1;
 jQuery( ".timeline__item__icon-wrap > div > div" ).replaceWith( number );
return ++number;
});
