<p>我正在使用 Symfony 框架，并且有一个由 EasyAdmin 插件自动生成的表单。我需要此表单仅显示无线电输入字段，但无论出于何种原因，EasyAdmin 都会创建复选框，而我还没有找到更改它的方法。</p>
<p>我遇到的问题是，当用户选中其中一个复选框时，必须取消选中所有其他复选框。换句话说，模拟无线电输入。</p>
<p>以下是创建复选框的 HTML：</p>
<ul>
<li>请注意，此复选框已选中。要取消选中复选框，请将属性<strong>btn-success</strong>更改为<strong>btn-danger</strong>，并添加另一个名为“<strong>off</strong>”的属性，第一个 div 的类声明。</li>
</ul>
<pre class="brush:php;toolbar:false;"><!-- Change btn-success to btn-danger, and add an additional class named "off" to the following div in order to uncheck checkboxes -->
<div class="toggle btn btn-xs btn-success" data-toggle="toggle" style="width: 38px; height: 23px;">
<input type="checkbox" data-toggle="toggle" data-size="mini" data-onstyle="success" data-offstyle="danger" data-on="Yes" data-off="No">
<div class="toggle-group">
<label class="btn btn-success btn-xs toggle-on">Yes</label>
<label class="btn btn-danger btn-xs active toggle-off">No</label>
<span class="toggle-handle btn btn-default btn-xs"></span>
</div>
</div></pre>
<p>我的代码目前看起来像这样</p>
<pre class="brush:php;toolbar:false;">$('#main').find('table .toggle input[type="checkbox"]').change(function() {
$('#main').find('div .toggle .btn .btn-xs .btn-success').not($(this)).removeClass("on").removeClass("btn-success").addClass("btn-danger").addClass("off");</pre>
<p>控制台中没有错误消息；任何帮助是极大的赞赏;过去两天这让我发疯:(
});</p>
<p>下面是当前不起作用的表单和 JavaScript：</p>
<p>
<pre class="snippet-code-js lang-js prettyprint-override"><code>$('#main').find('table .toggle input[type="checkbox"]').change(function() {

Anda boleh mengaitkan meja dan kemudian menggunakannya untuk mencari kotak pilihan. Saya menggunakan yang pertama diperiksa untuk menetapkan keadaan awal, tetapi jika tidak, anda mungkin perlu menyesuaikannya.
Mungkin memerlukan perincian lebih sedikit, hanya untuk menjadikan penyelesaiannya lebih jelas.
Setiap komen menjadikannya sentiasa terbuka. Jika anda ingin menghidupkan/mematikan secara berprogram, anda boleh
