页面初始化加载：

$(function() {
	 makeAll();
	 makeAllOrder();
});

var orderNumber=0;
function makeAll(){
	$.ajax({
		type : "post",
		dataType: "json",
		data : {
			
		},
		url : "${pageContext.request.contextPath }/quser/JSDAY.do",
		success : function(data) {
            //
			
		}
	});
}
function makeAllOrder(){
	$.ajax({
		type : "post",
		dataType: "json",
		data : {
			
		},
		url : "${pageContext.request.contextPath }/quser/JSListOrder.do",
		success : function(data) {
			//订单消息提醒
			var listOrder=data.listOrder;
			
			if(listOrder.length>orderNumber){
				//语音提示
				speckText("您有新的待处理订单");
			}
			orderNumber = listOrder.length;
			$("#weichuli1").html(listOrder.length);
			$("#quanbu1").html(listOrder.length);
            //拼接列表
			$("#xiaoxicon1").empty();
			var str1="";
			str1+="<li class='nav-header'>";
			str1+="<i class='icon-envelope'></i> <span id='quanbu1'>"+listOrder.length+"</span> 条待确认订单";
			str1+="</li>";
			
			for(var i = 0; i < listOrder.length; i++) {
				
				str1+="<li><a style='text-align: center;'>";
				//str1+="<span class='msg-body'>";
				str1+="<span class='msg-title'>"+listOrder[i].CONTENT+"</span>";
				str1+="</span>";
				//str1+="</span>";

	});
}

声音播放文本内容：

function speckText(str){
	var url = "http://tts.baidu.com/text2audio?lan=zh&ie=UTF-8&text=" + encodeURI(str);        
   
	var n = new Audio(url);

	n.src = url;

	n.play();
}

定时方法：

setInterval("makeAll()","3600000");
setInterval("makeAllOrder()","10000");
