【问题描述】：

所以我关注了bootstrap doc on who to init the popover，但它不起作用。它抛出了这个错误。我该如何解决这个问题？

Uncaught TypeError: bootstrap.Popover is not a constructor

这些是代码。

test_popover.html

  <button type="button" class="btn btn-lg btn-danger" data-bs-toggle="popover" title="Popover title" 
          data-bs-content="And here's some amazing content. It's very engaging. Right?">
    Click
  </button>

test_popover.js

  ...
  var popoverTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="popover"]'))
  var popoverList = popoverTriggerList.map(function (popoverTriggerEl) {
    return new bootstrap.Popover(popoverTriggerEl)
  })

我已在 packs/application.js 中导入引导程序

require("@rails/ujs").start()
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
    

// Import Bootstrap only ones that are used to reduce size
import 'bootstrap';
import '../javascripts/test_popover';

【解决方案1】：

这就是我修复它的方法。我导入Popover 并从新的bootstrap.Popover() 更改为new Popover()

import Popover from 'bootstrap/js/dist/popover';

document.addEventListener("turbolinks:load", function() {    
  var popoverTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="popover"]'))
  var popoverList = popoverTriggerList.map(function (popoverTriggerEl) {
    return new Popover(popoverTriggerEl)
  })
});
