css - 使用 Bootstrap 设置样式时，单选按钮不显示选中状态

问题描述

当我只使用一组带有 Bootstrap 且没有特殊样式的普通单选按钮时，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，如果我尝试使用这样的custom-controlCSS 类来设置按钮的样式：

    <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 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>
    
    <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

... 这没用。当我单击按钮时没有任何反应。我怎样才能解决这个问题？

解决方案

现在工作。您只需要id="customRadio"在输入和标签中添加 a 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>
