JavaScriptを使用して新しいタブでURLを開くにはどうすればよいですか?
JavaScript を使用して URL を新しいタブで開くには、window.open() メソッドを利用し、最初の引数として URL を指定し、2 番目の引数として _blank を指定して、新しいタブで開くことを指定します。これにより、ブラウザが新しいタブで URL を開くようになります。
window.open() メソッドの使用
- 新しいタブを開くには、次を使用する必要があります _空白 の 2 番目のパラメータで window.open() メソッド 。
- window.open() の戻り値は、新しく作成されたウィンドウまたはタブへの参照、または失敗した場合は null です。
- タブではなく新しいウィンドウが開かれるため、3 番目のパラメータを追加しないでください。
構文：
window.open(URL, '_blank');
例 1: この例では、上で説明したアプローチを使用しました。
HTML 新しいタブで URL を開く title>head> <body> <p>ボタンをクリックして開きます <b>techcodeview.com b> 新しいタブ p> <button onclick='NewTab()'>Geeksforgeeks ボタンを開く> <script>function NewTab() { window.open( 'https://www.techcodeview.com, '_blank'); } スクリプト>本体>html>> </pre> </code> <p dir='ltr'> <b> <strong>出力： </strong> </b> </p> <img src='//techcodeview.com/img/picked/09/how-open-url-new-tab-using-javascript.webp' alt='新しいタブ'> <h2> <span>アンカー要素（HTML DOM）の使用 </span> </h2> <p> <span>アンカー要素 (HTML DOM) を使用するには、「a」要素を動的に作成し、その href 属性を目的の URL に設定し、その target 属性を _blank に設定する必要があります。最後に、要素のクリック イベントをトリガーすると、新しいタブで URL が開きます。 </span> </p> <p dir='ltr'> <b> <strong>例： </strong> </b> <span>この例では、新しいタブで techcodeview.com を開くボタンを作成します。クリックすると、目的の URL と _blank ターゲットを含む「a」要素が動的に生成され、クリック イベントがトリガーされて新しいタブでリンクが開きます。 </span> </p>HTML <code> <pre> <html> <head> <title>新しいタブで URL を開く title>head> <body> <p>ボタンをクリックして開きます <b>techcodeview.com b> 新しいタブ p> <button onclick='NewTab()'>Geeksforgeeks ボタンを開く> <script>function NewTab() { let newTab = document.createElement('a'); newTab.href = 'https://www.techcodeview.com; newTab.target = '_blank'; newTab.click(); } スクリプト>本体>html>> </pre> </code> <p dir='ltr'> <span>出力： </span> </p> <img src='//techcodeview.com/img/picked/09/how-open-url-new-tab-using-javascript-2.webp' alt='新しいタブ'> <h3> <b> <strong>サポートされているブラウザ </strong> </b> </h3> <p dir='ltr'> <span>ブラウザは以下によってサポートされています。 </span> <b> <strong>window.open() </strong> </b> <span>方法は以下にリストされています。 </span> </p> <ul> <li value='1'> <span>グーグルクローム </span> </li> <li value='2'> <span>角 </span> <span> </span> </li> <li value='3'> <span>Firefox </span> </li> <li value='4'> <span>オペラ </span> </li> <li value='5'> <span>サファリ </span> </li> </ul> <br>
