$('#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>

在bootstrap 4中，我只使用$(el).tooltip('dispose');然后像往常一样重新创建。所以你可以把dispose放在创建工具提示的函数之前，以确保它不会折叠。

不得不检查状态和修补值似乎不太友好。

销毁任何已存在的工具提示，以便我们可以用新的工具提示内容重新填充

$(element).tooltip("destroy");    
$(element).tooltip({
    title: message
});

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();
}

$('#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>

$(this).attr('data-original-title', 'click here to publish')
       .tooltip('fixTitle')
       .tooltip('show');

如果你需要在使用attr 'data-original-title'初始化一个工具提示后更改它的文本，这很有用。
