Question

当我仅使用带有类似Bootstrap的普通单选按钮组而没有特殊样式时，它就可以正常工作：

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<div class="radio">

        <div class="form-group">
            <label><input type="radio" value="keep">Ändra inte lösenordet</label>
        </div>
        <div class="form-group">
            <label><input type="radio" value="auto">Generera ett nytt lösenord automatiskt</label>
        </div>
        <div class="form-group">
            <label><input type="radio" value="manual">Ange ett nytt lösenord manuellt</label>
        </div>
        <div class="form-group">
            <input type="text" class="form-control" class="custom-control-input" name="password" id="password" placeholder="Ange ett lösenord manuellt">
        </div>
                   
    </div>
    
    <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

单击时，单选按钮显示选中状态。但是，如果我尝试使用custom-control CSS类为按钮设置样式，

    <div class="radio custom-control custom-radio">

        <div class="form-group">
            <label class="custom-control-label"><input type="radio" class="custom-control-input" value="keep">Ändra inte lösenordet</label>
        </div>
        <div class="form-group">
            <label class="custom-control-label"><input type="radio" class="custom-control-input" value="auto">Generera ett nytt lösenord automatiskt</label>
        </div>
        <div class="form-group">
            <label class="custom-control-label"><input type="radio" class="custom-control-input" value="manual">Ange ett nytt lösenord manuellt</label>
        </div>
        <div class="form-group">
            <input type="text" class="form-control" class="custom-control-input" name="password" id="password" placeholder="Ange ett lösenord manuellt">
        </div>
                       
    </div>

...它不起作用。当我单击按钮时，什么也没有发生。我该如何解决？

现在工作。您只需要在输入中添加id="customRadio"，并在标签中添加for="customRadio"。

  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>


    <div class="radio custom-control custom-radio">

        <div class="form-group">
<input type="radio" class="custom-control-input" id="customRadio"><label class="custom-control-label" for="customRadio">Ändra inte lösenordet</label>
     </div>
     
        <div class="form-group">
            <input type="radio" id="customRadio1" class="custom-control-input" value="auto"><label class="custom-control-label" for="customRadio1">Generera ett nytt lösenord automatiskt</label>
        </div>
        
        <div class="form-group">
           <input type="radio" id="customRadio2" class="custom-control-input" value="manual" > <label class="custom-control-label" for="customRadio2">Ange ett nytt lösenord manuellt</label>
        </div>
        

        <div class="form-group">
            <input type="text" class="form-control" class="custom-control-input" name="password" id="password" placeholder="Ange ett lösenord manuellt">
        </div>
        
            
    </div>

自定义单选按钮（以及复选框）也取决于关于label和input的特定DOM结构，其中input必须先于{em> label，其中label是同胞（最常见的情况是，期望label是 adjacent 的同胞）。这是由于CSS的限制。

这意味着您的标签不再与单选按钮关联，因为它不再包装它。要解决此问题，请给单选按钮一个id，然后在包含相同for=""的标签上添加id属性。

此外，您的单选按钮需要共享一个公用的name，否则可以同时检查所有单选按钮。

要解决此问题，请根据以下内容进行更改：

<div class="radio custom-control custom-radio">

  <div class="form-group">
    <input type="radio" class="custom-control-input" name="i" value="keep" id="i1" />
    <label class="custom-control-label" for="i1">Ändra inte lösenordet</label>
  </div>
  <div class="form-group">
    <input type="radio" class="custom-control-input" value="auto" name="i" id="i2" />
    <label class="custom-control-label" for="i2">Generera ett nytt lösenord automatiskt</label>
  </div>
  <div class="form-group">
    <input type="radio" class="custom-control-input" name="i" value="manual" id="i3" />
    <label class="custom-control-label" for="i3">Ange ett nytt lösenord manuellt</label>
  </div>
  <div class="form-group">
    <input type="text" class="form-control" class="custom-control-input" name="password" id="password" placeholder="Ange ett lösenord manuellt">
  </div>

</div>
