bootstrap中的模态框（modal），不同于Tooltips，模态框以弹出对话框的形式出现，具有最小和最实用的功能集。务必将模态框的 HTML 代码放在文档的最高层级内（也就是说，尽量作为 body 标签的直接子元素），以避免其他组件影响模态框的展现或功能。 ![bootstrapwindows.jpg][1] 默认的modal示例 ---------- <!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Bootstrap Modal</title> <link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css"> </head> <body> <button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal"> Launch demo modal </button> <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> <h4 class="modal-title" id="myModalLabel">Modal title</h4> </div> <div class="modal-body"> <p>One fine body…</p> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save</button> </div> </div> </div> </div> <script src="http://cdn.bootcss.com/jquery/1.11.3/jquery.min.js"></script> <script src="http://cdn.bootcss.com/bootstrap/3.3.5/js/bootstrap.min.js"></script> </body> </html> **1. 为 .modal 添加 role="dialog"，用于指定模态框为对话框。 2. 为 .modal-dialog 添加 aria-hidden="true" 属性。 3. 通过 aria-describedby 属性为模态框 .modal 添加描述性信息。** 关闭动画 ---- 如果你不需要模态框弹出时的动画效果（淡入淡出效果），删掉 .fade 类即可。 通过按钮属性显示不同内容 当有一堆按钮，都要触发相同的模态框(如：向好友列表中某个人发消息)，只是有用户ID不同，那么可以使用data-whatever配合event.relatedtarget来实现： <!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Bootstrap Modal</title> <link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css"> </head> <body> <div class="panel panel-default"> <div class="panel-heading">好友列表</div> <div class="panel-body"> <div class="list-group" role="group" aria-label="好友列表"> <button type="button" class="list-group-item" data-toggle="modal" data-target="#exampleModal" data-whatever="张三">张三 </button> <button type="button" class="list-group-item" data-toggle="modal" data-target="#exampleModal" data-whatever="李四">李四 </button> <button type="button" class="list-group-item" data-toggle="modal" data-target="#exampleModal" data-whatever="王二">王二 </button> </div> </div> </div> <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="exampleModalLabel">New message</h4> </div> <div class="modal-body"> <form> <div class="form-group"> <label for="recipient-name" class="control-label">Recipient:</label> <input type="text" class="form-control" id="recipient-name"> </div> <div class="form-group"> <label for="message-text" class="control-label">Message:</label> <textarea class="form-control" id="message-text">
