如何在选中一个复选框后取消选中其他复选框？-PHP中文网问答

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。

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。

以下是创建复选框的 HTML：

请注意，此复选框已选中。要取消选中复选框，请将属性btn-success更改为btn-danger，并添加另一个名为“off”的属性，第一个 div 的类声明。

<!-- 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>

我的代码目前看起来像这样

$('#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");

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:( });

下面是当前不起作用的表单和 JavaScript：

$('#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");
});

您可以挂钩表格，然后使用它来查找复选框。我使用第一个检查的来设置初始状态，但如果没有，您可能需要调整它。

可能需要更详细一点，只是为了使解决方案更加清晰。

每一条评论都使其始终处于开启状态。如果您希望以编程方式打开/关闭它们，您可以将 'change' 事件更改为 click

您可以在更改事件处理程序中操作复选框的类。这不是选中/取消选中复选框的方式。

请阅读此使用 jquery 选中/取消选中复选框？和这个 jQuery。如何取消选中除一个（已选中）之外的所有复选框

以下是具体操作方法：

$('#main').find('table .toggle input[type="checkbox"]').change(function() {
  $('table .toggle input[type="checkbox"]').prop('checked', false);
  $(this).prop('checked', true);
});

这是工作示例：https://jsfiddle.net/fL9dknp7/
