別ウィンドウでブラウザを開閉するaタグ・JSの書き方

アプリケーションで一部の機能を別ウィンドウで表示させ、ウィンドウを閉じるリンクも設置させたい時

### 別ウィンドウのリンク
– aタグに直接window.openとして書きます。ここではwidth500 height400のウィンドウです。

<a href="./translate.html" onclick="window.open('./translate.html', '', 'width=500,height=400'); return false;">翻訳</a>

### ウィンドウを閉じる
– window.closeで閉じます。

<a class="nav-link btn-magnify" href="" id="close">ブラウザを閉じる</a>

// 省略

<script>
    let close = document.getElementById('close');
    close.addEventListener('click', ()=>{
      window.close();
    });
  </script>

中々良い感じです。

                      <tr class="{{ $quote->status == 1 ? 'table-secondary' : ''}}">
                        <td>{{ \Carbon\Carbon::parse($quote->created_at)->isoFormat("YYYY年MM月DD日(ddd) H:m") }}</td> // 省略
                      </tr>

class=”” 自体を三項方程式で切り分けたいが上手くいかないのでclassの中身だけを条件分岐としています。
しかし、bootstrap万能です。
