假设title属性用作工具提示的文本。是否可以使用jQuery更改文本？

  <a href="#" id="tool" data-toggle="tooltip" title="Hfdfd!">Hover over me</a>

    $('[data-toggle="tooltip"]').tooltip();   
});

我无法通过选项更改它，因为我相信api说使用标题是告诉它如果标题不在那里应该是什么值。我通过将标题更改为data-title并将标题选项作为返回此值的函数来实现它。

$(document).ready(function(){
    $('[data-toggle="tooltip"]').tooltip({
      title: function () {
        return this.getAttribute('data-title');
      }
    });
    
    setInterval(function(){
      $('[data-toggle="tooltip"]').attr('data-title', Date.now());
    }, 1000);
});

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<div class="container">
  <h3>Tooltip Example</h3>
  <a href="#" id="tool" data-toggle="tooltip" data-title="Hfdfd!">Hover over me</a>
</div>
