方式一:
1、在html的body中添加如下代码:
<div class="modal fade" id="loadingModal"> <div style="width: 200px;height:20px; z-index: 20000; position: absolute; text-align: center; left: 50%; top: 50%;margin-left:-100px;margin-top:-10px"> <div class="progress progress-striped active" style="margin-bottom: 0;"> <div class="progress-bar" style="width: 100%;"></div> </div> <h5>正在加载...</h5> </div> </div>
2、用jquery进行显示和隐藏
//显示 $("#loadingModal").modal('show'); //隐藏 $("#loadingModal").modal('hide');
3、其他设置
//使点击空白处遮罩层不会消失 $("#loadingModal").modal({backdrop:'static'}); //按Tab键遮罩层不会消失 ,默认值为true $("#loadingModal").modal({keyboard:false}); //也可以一起运用 //backdrop 为 static 时,点击模态对话框的外部区域不会将其关闭。 //keyboard 为 false 时,按下 Esc 键不会关闭 Modal。 $('#loadingModal').modal({backdrop: 'static', keyboard: false});
方式二(添加图片loader.gif):
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>遮罩层DEM</title> <!-- Bootstrap --> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <style type="text/css"> .loading { background: #00000040 url(loader.gif) no-repeat center 50%; z-index: 9999; } </style> </head> <body> <div class="container-fluid text-center"> <h2>遮罩层DEMO</h2> <!-- 按钮触发模态框 --> <button onclick="startup()">遮罩层</button> <!-- 遮罩层模态框(Modal) --> <div class="modal fade loading" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="static" data-keyboard="false"> // data-backdrop="static" data-keyboard="false" // 以上属性是静止掉了模态框的关闭按钮和点击空白处关闭模态框 </div> </div> <script> function startup() { $("#myModal").modal('show'); setTimeout('shutdown()', 5000); } function shutdown() { $("#myModal").modal('hide'); } </script> </body> </html>
