$('#topic_1').tooltip({title: 'Hello'}).tooltip('show'); setTimeout( function() { $('#topic_1').tooltip('dispose').tooltip({title: 'Goodbye'}).tooltip('show'); }, 5000); #topic_1 { border: 1px solid red; margin: 50px; } <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.2/css/bootstrap.min.css" integrity="sha384-Smlep5jCw/wG7hdkwQ/Z5nLIefveQRIY9nfy6xoR1uRYBtpZgI6339F5dgvm/e9B" crossorigin="anonymous"> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js" integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49" crossorigin="anonymous"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.2/js/bootstrap.min.js" integrity="sha384-o+RDsa0aLu++PJvFqy8fFScvbHFLtbvScb8AjopnFD+iEQ7wo/CG0xlczd+2O/em" crossorigin="anonymous"></script> <div id="topic_1">Topic 1</div>

Bootstrap 5不再有fixTitle或_fixTitle，所以我不得不处理整个Tooltip对象并重建它:

$('a.copy').click(function() {
    var tt = bootstrap.Tooltip.getInstance(this);
    tt.dispose();
    this.setAttribute('title', 'Copied!')
    tt = bootstrap.Tooltip.getOrCreateInstance(this);
    tt.show();
}

如果工具提示已经实例化(可能用javascript)，这是有效的:

$("#tooltip_id").data('tooltip').options.title="New_value!";
$("#tooltip_id").tooltip('hide').tooltip('show');

我只在bootstrap 4和w/o调用.show()中测试了这个

el.tooltip('hide').attr('data-original-title', 'message');

如果你想在不关闭和重新打开工具提示的情况下更改文本，这里有一个很好的解决方案。

$(element).attr('title', newTitle)
          .tooltip('fixTitle')
          .data('bs.tooltip')
          .$tip.find('.tooltip-inner')
          .text(newTitle)

这样，文本替换而不关闭工具提示(不重新定位，但如果你正在做一个词的改变等应该是好的)。当你将鼠标悬停在工具提示上时，它仍然在更新。

**这是bootstrap 3，对于2，你可能需要改变数据/类名
