javascript - 模态不在 href 上打开

Question

当我点击a href=....(特权一)时，它应该打开模式，但它没有打开。虽然 URL 栏更改为 project/index.php#privilege_10

$(document).ready(function() {

  $(window.location.hash).modal('show');

});

在Walks's的帮助下 comment 添加 data-toggle="modal"data-target="#privilege_10" 属性到 a 标签解决了这个问题。

$(document).ready(function() {

  $(window.location.hash).modal('show');

});

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<a href="#privilege_10" class="btn btn-lg btn-dark" data-toggle="modal" data-target="#privilege_10">Privilege</a>
