基于Bootstrap的表单或Ajax提交等待效果。

（第一步）引入bootstrap所需要样式与js。

    <!-- Bootstrap -->
    <!-- 新 Bootstrap 核心 CSS 文件 -->
	<link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap.min.css">

	<!-- 可选的Bootstrap主题文件（一般不用引入） -->
	<link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap-theme.min.css">

    <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
    <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
    <!--[if lt IE 9]>
      <script src="http://cdn.bootcss.com/html5shiv/3.7.2/html5shiv.min.js"></script>
      <script src="http://cdn.bootcss.com/respond.js/1.4.2/respond.min.js"></script>
    <![endif]-->
    <script src="http://cdn.bootcss.com/bootstrap/3.3.0/js/bootstrap.min.js"></script>

（第二步）HTML定义一个DIV。

	<div class="modal fade" id="myModal">
	  <div class="modal-dialog modal-sm">
		
		  <img alt="" src="data:image/gif;base64,R0lGODlhGQAZAJECAK7PTQBjpv///wAAACH/C05FVFNDQVBFMi4wAwEAAAAh/wtYTVAgRGF0YVhNUDw/eHBhY2tldCBiZWdpbj0i77u/IiBpZD0iVzVNME1wQ2VoaUh6cmVTek5UY3prYzlkIj8+IDx4OnhtcG1ldGEgeG1sbnM6eD0iYWRvYmU6bnM6bWV0YS8iIHg6eG1wdGs9IkFkb2JlIFhNUCBDb3JlIDUuNS1jMDE0IDc5LjE1MTQ4MSwgMjAxMy8wMy8xMy0xMjowOToxNSAgICAgICAgIj4gPHJkZjpSREYgeG1sbnM6cmRmPSJodHRwOi8vd3d3LnczLm9yZy8xOTk5LzAyLzIyLXJkZi1zeW50YXgtbnMjIj4gPHJkZjpEZXNjcmlwdGlvbiByZGY6YWJvdXQ9IiIgeG1sbnM6eG1wTU09Imh0dHA6Ly9ucy5hZG9iZS5jb20veGFwLzEuMC9tbS8iIHhtbG5zOnN0UmVmPSJodHRwOi8vbnMuYWRvYmUuY29tL3hhcC8xLjAvc1R5cGUvUmVzb3VyY2VSZWYjIiB4bWxuczp4bXA9Imh0dHA6Ly9ucy5hZG9iZS5jb20veGFwLzEuMC8iIHhtcE1NOk9yaWdpbmFsRG9jdW1lbnRJRD0ieG1wLmRpZDo5OTYyNTQ4Ni02ZGVkLTI2NDUtODEwMy1kN2M4ODE4OWMxMTQiIHhtcE1NOkRvY3VtZW50SUQ9InhtcC5kaWQ6RUNGNUFGRUFGREFCMTFFM0FCNzVDRjQ1QzI4QjFBNjgiIHhtcE1NOkluc3RhbmNlSUQ9InhtcC5paWQ6RUNGNUFGRTlGREFCMTFFM0FCNzVDRjQ1QzI4QjFBNjgiIHhtcDpDcmVhdG9yVG9vbD0iQWRvYmUgUGhvdG9zaG9wIENDIChXaW5kb3dzKSI+IDx4bXBNTTpEZXJpdmVkRnJvbSBzdFJlZjppbnN0YW5jZUlEPSJ4bXAuaWlkOjk5NjI1NDg2LTZkZWQtMjY0NS04MTAzLWQ3Yzg4MTg5YzExNCIgc3RSZWY6ZG9jdW1lbnRJRD0ieG1wLmRpZDo5OTYyNTQ4Ni02ZGVkLTI2NDUtODEwMy1kN2M4ODE4OWMxMTQiLz4gPC9yZGY6RGVzY3JpcHRpb24+IDwvcmRmOlJERj4gPC94OnhtcG1ldGE+IDw/eHBhY2tldCBlbmQ9InIiPz4B//79/Pv6+fj39vX08/Lx8O/u7ezr6uno5+bl5OPi4eDf3t3c29rZ2NfW1dTT0tHQz87NzMvKycjHxsXEw8LBwL++vby7urm4t7a1tLOysbCvrq2sq6qpqKempaSjoqGgn56dnJuamZiXlpWUk5KRkI+OjYyLiomIh4aFhIOCgYB/fn18e3p5eHd2dXRzcnFwb25tbGtqaWhnZmVkY2JhYF9eXVxbWllYV1ZVVFNSUVBPTk1MS0pJSEdGRURDQkFAPz49PDs6OTg3NjU0MzIxMC8uLSwrKikoJyYlJCMiISAfHh0cGxoZGBcWFRQTEhEQDw4NDAsKCQgHBgUEAwIBAAAh+QQFCgACACwAAAAAGQAZAAACTpSPqcu9AKMUodqLpAb0+rxFnWeBIUdixwmNqRm6JLzJ38raqsGiaUXT6EqO4uIHRAYQyiHw0GxCkc7l9FdlUqWGKPX64mbFXqzxjDYWAAAh+QQFCgACACwCAAIAFQAKAAACHYyPAsuNH1SbME1ajbwra854Edh5GyeeV0oCLFkAACH5BAUKAAIALA0AAgAKABUAAAIUjI+py+0PYxO0WoCz3rz7D4bi+BUAIfkEBQoAAgAsAgANABUACgAAAh2EjxLLjQ9UmzBNWo28K2vOeBHYeRsnnldKBixZAAA7" />
		
	  </div><!-- /.modal-dialog -->
	</div><!-- /.modal -->

（第三步）定义显示/隐藏函数。

function hideModal(){
		$('#myModal').modal('hide');
	}
	
	function showModal(){
		$('#myModal').modal({backdrop:'static',keyboard:false});
	}

（第四步）测试。

	function initCalendar(){
		if(window.confirm('确定初始化？')){
			var moment = cal.fullCalendar('getDate');
			var y = moment.format();
			var sp = y.split("-");
			
			$.ajax({
				url: "./FullCanlendarInit", 
				async:false,
				type:"POST",
				data:{year:sp[0]},
				beforeSend:function (){
					showModal();
				},
				success: function(data){
					if(data.success==='init'){
						alert("init ok");
						hideModal();
					}else{
						alert("init error");
						hideModal();
					}
		      }
			});
			
			window.location.reload();
		}
	}

OK，测试完成，好用。
