JQM Toggle switch、selectmenu动态设置默认选中值时没有效果的问题

静态时,ok,没问题,如下:
<label for="swicher" class="ui-hidden-accessible">Notification:</label>
		<select data-track-theme="b" data-theme="c" name="swicher" id="swicher" data-role="slider" data-mini="true" onchange="onNotification(this)">
			<option value="off">Off</option>
			<option value="on" selected>On</option>
		</select>


动态时需要jquery选择:
var storeNotification="on";
$("#swicher option[value='"+storeNotification+"']").attr("selected",true);
如果只写上面这句话时,不会有任何效果,需要加上下面这句:
$('#swicher').slider("refresh");

事实上,很多JQM控件在动态添加或删除时都有这样的问题,需要及时"refresh"。

下面是selectmenu的“refresh”
<fieldset data-role="controlgroup" >
			   <select name="month" id="month" data-native-menu="true" data-theme="b">
			        <option value='' disabled selected>Month</option>
			    </select>
			    <select name="day" id="day" data-native-menu="true" data-theme="b">
			     	<option value='' disabled selected>Day</option>
			    </select>
			    <select name="year" id="year" data-native-menu="true" data-theme="b">
			        <option value='' disabled selected>Year</option>
			    </select>
			</fieldset>



	var d = new Date();
	var year=d.getFullYear();
	var month=d.getMonth()+1;
	var day=d.getDate();
//	log(year+"-"+month+"-"+day);
	var days=31;

	$("#change_birthday_page #month").empty();
	$("#change_birthday_page #month").append("<option value='' disabled selected>Month</option>");
	for(var i=1;i<13;i++){
		$("#change_birthday_page #month").append("<option value='"+i+"'>"+i+"</option>");
	}
	$("#change_birthday_page #day").empty();
	$("#change_birthday_page #day").append("<option value='' disabled selected>Day</option>");
	for(var i=1;i<days+1;i++){
		$("#change_birthday_page #day").append("<option value='"+i+"'>"+i+"</option>");
	}
	$("#change_birthday_page #year").empty();
	$("#change_birthday_page #year").append("<option value='' disabled selected>Year</option>");
	for(var i=1970;i<year;i++){
		$("#change_birthday_page #year").append("<option value='"+i+"'>"+i+"</option>");
	}
	
	$("#change_birthday_page #month").selectmenu( "refresh" );
	$("#change_birthday_page #day").selectmenu( "refresh" );
	$("#change_birthday_page #year").selectmenu( "refresh" );
