javascript - How to select a tag via href in jquery -


i've search it. not same other's problem. want select <a> tag using href attribute. please see code below:

<div class="jump-to">    <ul>      <li>no a</li>      <li class="with-a">         <a href="hello1">has a</a>      </li>      <li class="with-a">         <a href="hello8">has a</a>      </li>      <li class="with-a">         <a href="hello10">has a</a>      </li>    </ul> </div> 
var current_anchor = window.location.href; var left_anchor = $(".jump-to ul li.with-a a[href="+ current_anchor +"]").prev("li a").attr("href");  alert(left_anchor);

the selection via href attribute working fine. problem because dom traversal incorrect.

prev('li a') not valid a li not sibling. need first use closest('li') parent, prev(), find('a'), this:

var current_anchor = 'http://localhost/myproject/hello8';  var left_anchor = $('.jump-to ul li.with-a a[href="' + current_anchor + '"]').closest('li').prev('li').find('a').attr('href');  console.log(left_anchor);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div class="jump-to">    <ul>      <li>no a</li>      <li class="with-a">        <a href="http://localhost/myproject/hello1">has a</a>      </li>      <li class="with-a">        <a href="http://localhost/myproject/hello8">has a</a>      </li>      <li class="with-a">        <a href="http://localhost/myproject/hello10">has a</a>      </li>    </ul>  </div>
