如何解决使用 Svelte 和 Routify 时不会出现 Bootstrap 模态
在我的项目中，我使用 Routify、Bootstrp、svelte 和 Webpack 来构建我的前端。如果我添加一个与 Bootstrap's documentation 中提供的模式相同的模式和一个打开它的按钮，同样与文档几乎相同，点击按钮绝对没有任何作用——没有模式打开，也没有错误记录在 JS 中控制台：
<!-- in a navbar,which renders correctly -->
<button class="btn btn-outline-primary" href="#" data-toggle="modal" data-target="#exampleModal">My Button</button>
<!-- ... -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
为了解决这个问题，我尝试使用 jQuery 打开模型：
<script>
import jquery from 'jquery';
function openModal(){
jquery('#exampleModal').modal('')
}
</script>
<button class="btn btn-outline-primary" href="#" on:click={() => openModal()}>My Button</button>
<!-- The modal is the same as in the prevIoUs example. -->
在模态没有打开的情况下产生相同的行为，但在 JS 控制台中记录了以下错误：
Uncaught TypeError: jquery__WEBPACK_IMPORTED_MODULE_3___default()(...).modal is not a function
各种样板文件如下：
index.js:
import 'bootstrap/dist/css/bootstrap.min.css';
import 'bootstrap';
import 'jquery';
import '@fortawesome/fontawesome-free/css/all.css'
import App from './App.svelte';
const app = new App({
target: document.body
});
