Question

在我的表格中，我有一组单选按钮：

 <div class="btn-group" data-toggle="buttons">
    <label class="btn btn-danger">
        <input name="Status" type="radio" value="2">Failed</label>
    <label class="btn btn-warning">
        <input name="Status" type="radio" value="0">Pending</label>
    <label class="btn btn-success active">
        <input name="Status" type="radio" value="1">Success</label>
 </div>

当我选择一个无线电选项并提交表单时，一切都按预期工作，但如果我双击一个选项，该选项会被破坏，并且不会与表单提交一起发送，除非我检查另一个选项。

看起来data-toggle="buttons"属性会导致问题。

这是Demo

Answer 1

刚发现这是一个已知错误：https://github.com/twbs/bootstrap/issues/9920

Answer 2

我在Github问题页面中看到了这个解决方案。这对我有用。

临时解决方案：

    $("input[type=radio][name=gender]").on("change", function(){
         $(this).prop('checked', true);
    });

Answer 3

看起来这是v3.0中的一个已知错误，将在下一个版本中修复

Radio checked property is removed on second click with data-toggle="buttons

Answer 4

我搜索了很多，发现这是一个bug，但现在已经解决了。参考https://github.com/twbs/bootstrap/issues/9920

已解决v3.0.2中的问题，请确定是否每晚构建或正式发布[Github]。您可以使用特定的bootstrap js文件作为按钮，而不是使用bootstrap.min.js。 https://github.com/twbs/bootstrap/blob/5d6e9212a642430719702ead322103e19c6aa782/js/button.js

尝试使用bootstrap.button.js，文件内容如下：

  $.fn.button.Constructor = Button
