javascript - 引导选项卡选项卡（“显示”）拒绝工作

问题描述

再会，

我正在创建一个带有引导选项卡（BS4）的页面。

现在我需要一个前进和后退按钮表单导航，并且我想使用 BS4 的选项卡（“显示”）功能。

然而，即使在概念验证中，我也无法让它发挥作用。我想知道我做错了什么。

我检查了是否设置了所有 ID 以及是否所有内容都匹配。到目前为止一切都是正确的。控制台日志没有给我任何错误或任何错误。

我希望我正在制作一个简单的错误，这不是引导问题。

在我的概念验证代码下方：

我的functions.js文件的内容：

function activaTab(tab) {
    var tabID = '#' + tab;
    console.log('You just clicked on a function to activate tab : ' + tabID);

    if ($(tabID).length == 0) {
        console.log('But I have to inform you of the misfortunate event that the tab ID you want to pick strangely does not exist');
    }

    $('.nav-tabs a[href="' + tabID + '"]').tab('show'); // Select tab by name
};

我的 HTML 文件的内容：

function activaTab(tab) {
    var tabID = '#' + tab;
    console.log('You just clicked on a function to activate tab : ' + tabID);

    if ($(tabID).length == 0) {
        console.log('But I have to inform you of the misfortunate event that the tab ID you want to pick strangely does not exist');
    }

    $('.nav-tabs a[href="' + tabID + '"]').tab('show'); // Select tab by name
};

编辑：

一个非常疲惫的头脑导致了这个..

$('.nav-tabs a[href="' + tabID + '"]').tab('show'); // 按名称选择标签

要更改：

$('.nav-pills a[href="' + tabID + '"]').tab('show'); // 按名称选择标签

标签： javascripthtmlcsstwitter-bootstrap

解决方案

在您的 activaTab() 方法中，您正在对具有类名nav-tabs的元素调用tab('show')，但您希望显示的元素具有类nav-pills。正确的调用应该是：

$('.nav-pills a[href="' + tabID + '"]').tab('show'); // Select tab by name
