使用window.getSelection().toString()可以获取鼠标选用的内容
demo:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
</head>
<body>
  <p class="text">123</p>

  <script>
    window.onload = function() {
      document.querySelector('.text').addEventListener('click', SelectText, true)
      function SelectText() {
        var selecter = window.getSelection().toString()
        console.log(selecter)
      }
    }
  </script>
</body>
</html>
