这对我很管用。

$('.nav-pills > li > a').click( function() {
    $('.nav-pills > li.active').removeClass('active');
    $(this).parent().addClass('active');
} );

与Gerben Rampaart的bootstrap 5 tab类似。只是与文档中当前标签HTML的一些差异:

$('button[data-bs-toggle="tab"]').on('shown.bs.tab', function (e) { var target = $(e.target).data("bs-target") // activated tab alert(target); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js"></script> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet"/> <nav> <div class="nav nav-tabs" id="nav-tab" role="tablist"> <button class="nav-link active" id="nav-home-tab" data-bs-toggle="tab" data-bs-target="#nav-home" type="button" role="tab" aria-controls="nav-home" aria-selected="true">Home</button> <button class="nav-link" id="nav-profile-tab" data-bs-toggle="tab" data-bs-target="#nav-profile" type="button" role="tab" aria-controls="nav-profile" aria-selected="false">Profile</button> <button class="nav-link" id="nav-contact-tab" data-bs-toggle="tab" data-bs-target="#nav-contact" type="button" role="tab" aria-controls="nav-contact" aria-selected="false">Contact</button> </div> </nav> <div class="tab-content" id="nav-tabContent"> <div class="tab-pane fade show active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">...</div> <div class="tab-pane fade" id="nav-profile" role="tabpanel" aria-labelledby="nav-profile-tab">...</div> <div class="tab-pane fade" id="nav-contact" role="tabpanel" aria-labelledby="nav-contact-tab">...</div> </div>

我用另一种方法。

试着找到所有id从某个子字符串开始的a。

JS

$('a[id^=v-photos-tab]').click(function () {
     alert("Handler for .click() called.");
});

HTML

<a class="nav-item nav-link active show"  id="v-photos-tab-3a623245-7dc7-4a22-90d0-62705ad0c62b" data-toggle="pill" href="#v-photos-3a623245-7dc7-4a22-90d0-62705ad0c62b" role="tab" aria-controls="v-requestbase-photos" aria-selected="true"><span>Cool photos</span></a>

$(function () {
    $('#myTab a:last').tab('show');
});

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
    var target = $(e.target).attr("href");
    if ((target == '#messages')) {
        alert('ok');
    } else {
        alert('not ok');
    }
});

问题是attr('href')从来不是空的。

或者比较#id = "#some value"，然后调用ajax。

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) { var target = $(e.target).attr("href") // activated tab alert(target); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/> <ul id="myTab" class="nav nav-tabs"> <li class="active"><a href="#home" data-toggle="tab">Home</a></li> <li class=""><a href="#profile" data-toggle="tab">Profile</a></li> </ul> <div id="myTabContent" class="tab-content"> <div class="tab-pane fade active in" id="home"> home tab! </div> <div class="tab-pane fade" id="profile"> profile tab! </div> </div>

这对我很管用。

$('.nav-pills > li > a').click( function() {
    $('.nav-pills > li.active').removeClass('active');
    $(this).parent().addClass('active');
} );
