easyUI时间的先后的判断

$('#start_time').datebox({
    onSelect: function(date){
        　  var curr_time = new Date(); 
           var curr_date = curr_time.getFullYear()+''+fullnum(curr_time.getMonth())+''+fullnum(curr_time.getDate());
           var select_date = date.getFullYear()+''+fullnum(date.getMonth())+''+fullnum(date.getDate());
          if(select_date>curr_date){
              return true;
          }else{
              $("#start_time").datebox("setValue",curr_time.getFullYear()+":"+(curr_time.getMonth()+1)+":"+curr_time.getDate());  
          }
    }
});

function fullnum(obj){//对于月小于10格式的转换,因为Timestamp转换必须是2013-01-04这种格式
    if(Number(obj) < 10){
       return '0' + obj;
    }else{
       return obj;
    }
}
