日期比较

比较日期：

	function compareDate(source){
				  var dateFromVal = document.getElementById("dateFrom").value;
				  var dateToVal = document.getElementById("dateTo").value;
				  var d1Arr=dateFromVal.split('-');
				  var d2Arr=dateToVal.split('-');
				  var v1=new Date(d1Arr[0],d1Arr[1],d1Arr[2]);
				  var v2=new Date(d2Arr[0],d2Arr[1],d2Arr[2]);
				  if(dateFromVal != "" && dateToVal != ""){
					  if(v1 > v2){
						if(source == "from"){
						  alert("开始日期不能大于结束日期，请重新选择！");
						}else if(source == "to"){
						  alert("结束日期不能小于开始日期，请重新选择！");
						}
					  }
				  }
			}

 

 dojo方式，实际上还是js方式

require(["dojo/dom","dojo/on","dojo/query","dojo/domReady!"],function(dom, on,query){
		 on(dom.byId("search"),"click",function(){
			 var dateFromVal = document.getElementById("dateFrom").value;
			  var dateToVal = document.getElementById("dateTo").value;
			  var startdate=dateFromVal.split("-");
			  var enddate=dateToVal.split("-");
			 var starttime = new Date(startdate[0],startdate[1],startdate[2]);
	      	 var starttimes = starttime.getTime();
	      	var endtime =  new Date(enddate[0],enddate[1],enddate[2]);
	      	var lktimes = endtime.getTime();
	        if(starttimes > lktimes){
	        	alert("开始日期不能大于结束日期，请重新选择！");
	        	return false;
	        }
			});
		});
