动态生成时引导选项卡不起作用答案

【问题标题】：Bootstrap tabs not working while generated dynamically动态生成时引导选项卡不起作用
【发布时间】：2020-09-07 18:47:35
【问题描述】：

我在我的网站中使用以下 bootstrap tab，它是从 ajax 请求动态生成的。

当我尝试这些选项卡的静态版本时，一切都运行良好，但现在当我按下选项卡时动态生成所有选项卡和窗格时，它只是没有将显示属性设置为它的窗格..

随着内容是动态添加的，点击时由.on('click', 'a'..)组成

这里是代码 sn-p...

我只是找不到我生成的错误，因为动态代码等于静态代码..

$('#tab').on('click', 'a', function(e) {
  e.preventDefault()
  $(this).tab('show');
})

【解决方案1】：

不能 100% 确定原因。我怀疑这是因为没有附加引导事件处理程序，因为您说选项卡是使用 ajax 请求生成的。

我在您的示例中使用了 javascript，并更改了选项卡。希望这可以帮助。

$('#tab').on('click', 'a', function(e) {
  dataId = $(this).data('id');
  $("[id$='-tab']").hide();
  $('#'+dataId+'-tab').show();
  e.preventDefault();
})
