要预附加或附加单选按钮和复选框而不是文本，可以尝试运行以下代码：
<!DOCTYPE html> <html> <head> <title>Bootstrap Example</title> <link href = "/bootstrap/css/bootstrap.min.css" rel = "stylesheet"> <script src = "/scripts/jquery.min.js"></script> <script src = "/bootstrap/js/bootstrap.min.js"></script> </head> <body> <div style = "padding: 100px 100px 10px;background: orange"> <form class = "bs-example bs-example-form" role = "form"> <div class = "row"> <div class = "col-lg-6"> <div class = "input-group"> <span class = "input-group-addon"> <input type = "checkbox"> </span> <input type = "text" class = "form-control"> </div><!-- /input-group --> </div><!-- /.col-lg-6 --><br> <div class = "col-lg-6"> <div class = "input-group"> <span class = "input-group-addon"> <input type = "radio"> </span> <input type = "text" class = "form-control"> </div><!-- /input-group --> </div><!-- /.col-lg-6 --> </div><!-- /.row --> </form> </div> </body> </html>
