Jquery easyui example of judging when the start time is less than the end time

If the start time is less than the end time, please refer to ValidateBox in jquery easyui
All right! Direct up code

 
 View contents: by time:  
<input class="easyui-datetimebox" style="width: 180px" id="start2" value="${startTime}"> 
<span class="newfont06"> to </span> 
<input class="easyui-datetimebox" style="width: 180px" id="end2" value="${endTime}" validType="md['#start2']"> 
<input name="Submit4" type="button" class="right-button02" value=" check   polling " onclick="query2('${pid}');" id="query"/> 

 
<script type="text/javascript"> 
var varify;//Used for query validation to verify that the start time is less than the end time
function query2(pid){ 
if(varify){ 
startTime2 = $('#start2').datetimebox('getValue'); 
endTime2 = $('#end2').datetimebox('getValue'); 
window.location.href="listPagingArticle?pid="+pid+"&pageNumber=1&start="+startTime2+"&end="+endTime2; 
}else{ 
$.messager.alert(' warning ',' The end time is greater than the start time ','warning'); 
} 

} 
$.fn.datebox.defaults.formatter = function(date){//Conversion of time format

var y = date.getFullYear(); 
var m = fullnum(date.getMonth()+1); 
var d = fullnum(date.getDate()); 
return y+'-'+m+'-'+d; 
}; 
function fullnum(obj){//For conversions in formats less than 10 months, the Timestamp conversion must be in the format of 2013-01-04
if(Number(obj) < 10){ 
return '0' + obj; 
}else{ 
return obj; 
} } 

$.extend($.fn.validatebox.defaults.rules, {//The validation start time is less than the end time
md: { 
validator: function(value, param){ 
startTime2 = $(param[0]).datetimebox('getValue'); 
var d1 = $.fn.datebox.defaults.parser(startTime2); 
var d2 = $.fn.datebox.defaults.parser(value); 
varify=d2>d1; 
return varify; 

}, 
message: ' End time is greater than start time! ' 
} 
}) 
</script>
