Modal Bootstrap 4 不显示
[英]Modal Bootstrap 4 doesn't show
问题描述
我有一个按钮可以打开 Bootstrap 4 模式。
这是html：
<button
type="button"
class="btn btn-info btn-circle btn-sm"
data-toggle="modal"
data-target="#editModal"
id="btn-modal"
>
<i class="fas fa-fw fa-pencil-alt"></i>
</button>
<div
class="modal fade"
id="editModal"
tabindex="-1"
role="dialog"
aria-labelledby="editModalLabel"
aria-hidden="true"
>
<div class="modal-dialog" role="document">
<form method="post" action="xx">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="editModalLabel">Edit</h4>
<button type="button" class="close" data-dismiss="modal">
×
</button>
</div>
<div class="modal-body">
//Modal Body
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">
<i class="fas fa-times" style="margin-right:5px"></i> Cancel
</button>
<button type="submit" name="submit" class="btn btn-success">
<i class="fas fa-location-arrow " style="margin-right:5px"></i> Save
</button>
</div>
</div>
</form>
</div>
</div>
这是 JavaScript：
$('#btn-modal').on('click', function(){
$("#editModal").modal('show');
});
我在 js 函数中添加了console.log("clicked")并且它显示在控制台中。 但是，模态仍然没有显示。 有人可以告诉我正确的方法吗？ 谢谢你。

确保在页面末尾附近导入所有 js 文件，就在关闭</body>标记之前，以启用它们。 jQuery 必须先来，然后是 Popper.js，然后是我们的 JavaScript 插件，而且不需要 js 代码。

你的代码对我有用。 最多删除不需要的JS。
这是一个带有你自己代码的 jsFiddle ，减去 JS，它工作得很好！

这是整个 HTML 文件。 如果这不起作用，您可能在浏览器中切换了 JavaScript？！
