title: Share Facebook or Line with onclick function, but get SEO problem "Links are not crawlable"
body: <p>I share Facebook and Line with onclick function:</p>
  <pre><code>
  &lt;a href=&quot;javascript:void(0);&quot; onclick=&quot;window.open('http://www.facebook.com/share.php?u='.concat(encodeURIComponent(location.href)), '', 'menubar=no,toolbar=no,resizable=no,scrollbars=yes,height=700,width=550')&quot; title=&quot;Facebook Share&quot; aria-label=&quot;Facebook Share&quot;&gt;
  
  &lt;a href=&quot;javascript:void(0);&quot; onclick=&quot;window.open('http://line.naver.jp/R/msg/text/?Page title%0A'.concat(encodeURIComponent(location.href)),'Share with Line', config='height=700,width=550')&quot; title=&quot;Line Share&quot; aria-label=&quot;Line Share&quot;&gt;
  
  </code></pre>
  <p>Google Lighthouse result:</p>
  <blockquote>
  <p>Search engines may use <code>href</code> attributes on links to crawl websites. Ensure that the <code>href</code> attribute of anchor elements links to an appropriate destination, so more pages of the site can be discovered.</p>
  </blockquote>
  <p>So I couldn't use <code>&lt;a&gt;</code> element, if want to open link with new window?</p>
