jquery日期比较

jQuery.validator.addMethod("compareDate", function(valuebg, element, param) {
var valuend = $(param).val();
if(valuebg != "" && valuend!="") {
var datebg = valuebg.substring(0,10);
var datend = valuend.substring(0,10);
var datebgArr1 = datebg.split('-');
var datendArr2 = datend.split('-');
var datebg1 = new Date(datebgArr1[0],datebgArr1[1],datebgArr1[2]);
var datend2 = new Date(datendArr2[0],datendArr2[1],datendArr2[2]);
if(datebg1.getTime()<datend2.getTime()){
return true;
}else if(datebg1.getTime()>datend2.getTime()){
return false;
}
var time1 = valuebg.substring(11).split(':');
var time2 = valuend.substring(11).split(':');
if(time1[0]>time2[1]){
return false;
}
if(time1[1]>time2[1]){
return false;
}
if(time1[2]>time2[2]){
return false;
}
return true;
}
return true;

}, '开始不能大于结束时间');

"beginTime":{
compareDate:"#endTime"
}
