为什么这些几乎相同的HTML表单中只有一个是响应提交按钮单击的？

Question

我有两张几乎一模一样的表格。一个用于编辑项目，另一个用于创建项目。由于某些原因，create-form根本不会对提交按钮单击做出反应，而edit/update表单则完全按照预期工作。我找不到两者之间的任何差异，这应该导致这种行为。

我确信这与后端没有任何关系。我已经监视了网络活动，但create-form的submit按钮根本没有激活任何类型的网络活动。

工作更新表单：

@extends ('layout')

@section('middle-content')

    <div class="wrapper">
        <div id="page" class="container">
            <h4>Edit Competition Category</h4>

            <form method="POST" action="/competition-categories/{{$competitionCategory->id}}">
                @csrf
                @method('PUT')

                <div class="form-group row">
                    <label for="competition-category-name-input" class="col-4 col-form-label">Name</label>
                    <div class="col-8">
                        <input id="competition-category-name-input" name="name" type="text" class="form-control" required="required" value="{{ $competitionCategory->name }}">
                    </div>
                </div>
                <div class="form-group row">
                    <label for="competition-category-abbreviation-input" class="col-4 col-form-label">Abbreviation</label>
                    <div class="col-8">
                        <input id="competition-category-abbreviation-input" name="abbreviation" type="text" class="form-control" required="required" value="{{ $competitionCategory->abbreviation }}">
                    </div>
                </div>
                <div class="form-group row">
                    <div class="offset-4 col-8">
                        <button name="submit" type="submit" class="btn btn-primary">Submit</button>
                    </div>
                </div>
            </form>
        </div>
    </div>

无响应create-form：

@extends ('layout')

@section('middle-content')

    <div class="wrapper">
        <div id="page" class="container">
            <h4>New Competition Category</h4>

            <form method="POST" action="/competition-categories"></form>
                @csrf

                <div class="form-group row">
                    <label for="competition-category-name-input" class="col-4 col-form-label">Name</label>
                    <div class="col-8">
                        <input id="competition-category-name-input" name="name" type="text" class="form-control" required="required">
                    </div>
                </div>
                <div class="form-group row">
                    <label for="competition-category-abbreviation-input" class="col-4 col-form-label">Abbreviation</label>
                    <div class="col-8">
                        <input id="competition-category-abbreviation-input" name="abbreviation" type="text" class="form-control" required="required">
                    </div>
                </div>
                <div class="form-group row">
                    <div class="offset-4 col-8">
                        <button name="submit" type="submit" class="btn btn-primary">Submit</button>
                    </div>
                </div>
            </form>
        </div>

Answer 1

这一行:你的非工作表单的<form method="POST" action="/competition-categories"></form>，请删除你启动并关闭它的</form>这就是原因。
