<script language="javascript">
function checkTime(){
	  	var begin=document.mainform.mod_begin.value;
	  	var end =document.mainform.mod_end.value;
	  	
	  	if(begin==""){
	  		alert("Please select start date");
	  		return false;
	  	}
	  	
	  	var today = new Date();
	  	var xYear=today.getFullYear();
    
	    var xMonth=today.getMonth()+1;
	    if(xMonth<10){
	        xMonth="0"+xMonth;
	    }

	    var xDay=today.getDate();
	    if(xDay<10){
	        xDay="0"+xDay;
	    }
	
	    var xHours=today.getHours();
	    if(xHours<10){

	    }
	
	    var xMinutes=today.getMinutes();
	    if(xMinutes<10){
	        xMinutes="0"+xMinutes;
	    }
	
	    var xSeconds=today.getSeconds();
	    if(xSeconds<10){
	        xSeconds="0"+xSeconds;
	    }

			var now = xYear+xMonth+xDay
			//alert("begin"+ begin +"| now = "+ now);
			
			if(begin < now) {
			  alert("The Order start Day can't earlyer than today!");
			  return false;
			}		
			  	
	  	if(end!=""){
	  			if(document.mainform.mod_begin.value>document.mainform.mod_end.value){//时间段判断
	  	       alert("The Order start Date can't larger than the end Date!");
	  	       return false;
	  	    }
	  	} 	
			
      
  	  document.mainform.action="action.do";
  	  document.mainform.submit();
}
</script>
