Есть ли способ обнаружить щелчок мыши или событие наведения мыши при выделении текста, но фактически пропустить при выделении текста?

 <div id="editor">
    <p>What is Lorem Ipsum?</p>

    <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industryamp;#39;s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum</p>

</div>

<div id="status"></div>
  

И вот мой js-код

 $(function() {
    $('#editor').on('mouseup', function(e) {
        let selection = window.getSelection().toString().length;
        let targetContainsSelection = e.target.contains(window.getSelection().baseNode);

        if(selection > 0 amp;amp; targetContainsSelection) {
            $('#status').text('true');
        } else {
            $('#status').text('false');
        }
    });
})
  

Желаемое решение заключается в том, чтобы текст состояния был верным только при нажатии на выделенный текст, но не при выборе.

Вы можете добавить mousedown прослушиватель и отслеживать, было ли выделение при запуске действия (щелчок или выделение). Вот пример:

 $(function() {
  let hasSelection = false;
  $('#editor').on('mousedown', function() {
    hasSelection = document.getSelection().toString().length;
  }).on('mouseup', function(e) {
    if (hasSelection) {
      let selection = window.getSelection().toString().length;
      let targetContainsSelection = window.getSelection().containsNode(e.target, true);

      if (selection > 0 amp;amp; targetContainsSelection) {
        $('#status').text('TRUE').css('color', 'green');
      }
    } else {
      $('#status').text('FALSE').css('color', 'red');
    }
  });
});  

 #status {
  font-weight: bolder;
  color: red;
}

Я изменил e.target.contains(window.getSelection().baseNode); на window.getSelection().containsNode(e.target, true); , потому что, e.target.contains(window.getSelection().baseNode); кажется, всегда есть false в FireFox.
