要设置禁用状态，请使用禁用类。
您可以尝试为按钮的禁用状态运行以下代码-
<!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> <p>The following are some buttons:</p> <button type = "button" class = "btn btn-default btn-lg "> Default Button </button> <button type = "button" class = "btn btn-default btn-lg" disabled = "disabled"> Disabled Button </button> </body> </html>
