You can use .attr() with callback function instead .each()

$(".to-attach").attr("href", function(){
    return $(this).prev("ul").find(".child-link").attr("href");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrap">
  <ul class="main-ul">
    <li>
      <a class="child-link" href="link1">child-link</a>
    </li>
  </ul>
  <a class="to-attach" href="">to-attach</a>   
  <ul class="main-ul">
    <li>
      <a class="child-link" href="link2">child-link</a>
    </li>
  </ul>
  <a class="to-attach" href="">to-attach</a>   
  <ul class="main-ul">
    <li>
      <a class="child-link" href="link3">child-link</a>
    </li>
  </ul>
  <a class="to-attach" href="">to-attach</a>   
</div>
