Php 如果存在验证错误，如何打开模式？

我有以下代码，如果用户未经身份验证，则显示此“登录”链接：

模态：

<div class="modal fade" id="login_modal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-sm">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Login</h5>
        <button type="button" class="close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">

            <form class="clearfix" method="POST" action="{{ route('login') }}">

@if ($errors->any())

     <ul>
        @foreach ($errors->all() as $error)
            <li>{{ $error }}</li>
        @endforeach
     </ul>

@endif

@if（$errors->any（））

@foreach（$errors->all（）作为$error）
{{$error}}
@endforeach

@恩迪夫

您应该使用ajax，当您使用php发布时，它会刷新页面。谢谢，但是它不适用于类似“@if（$errors->any（））alert（“test”）；$（“#login_modal”）。on（'show.bs.modal'，function（）{}）@endif”之类的东西？如果这不起作用，警报会显示，但模式不会打开。您也可以通过javascript通过

yourResponse.responseJSON

获取错误。无论如何，如果你想做点击操作，你只需像这样触发点击即可。触发（'click'）在你的情况下，它将是

$（'show#login_modal'）。触发（'click'）

我猜。谢谢，但也不适用于“@if（$errors->any（））警报（'test”）；$（'show#login_modal'）。触发（'click'）；@endif“。但警报可以工作。
