JS中日期、时间比较是否相等

function dateEqu(date1,date2){
var arr1 = date1.split("-");
var startDate = new Date(arr1[0],arr1[1],arr1[2]);
var startDates = startDate.getTime();

var arr2 = date2.split("-");
var endDate = new Date(arr2[0],arr2[1],arr2[2]);
var endDates = endDate.getTime();
if(startDates == endDates){
alert("时间未变更，请变更时间！");
return false;
}
}

<script type="text/javascript">
function timeEqu(){
var bgqzbsj = $("#bgqsj").val();
var zbsj = $("#zbsj").val();
bgqzbsjs = bgqzbsj.substring(0,10).split("-");
zbsjs = zbsj.substring(0,10).split("-");
bgqzbsj = bgqzbsjs[1] + "-" + bgqzbsjs[2] + "-" + bgqzbsjs[0] + " " + bgqzbsj.substring(10,19);
zbsj = zbsjs[1] + "-" + zbsjs[2] + zbsjs[0] + " " + zbsj.substring(10,19);
var result = (Date.parse(zbsj) - Date.parse(bgqzbsj))/3600/1000;
if(result == 0){
if(!confirm("时间未变更，确定要转出吗？")){
return;
}
}

}
</script>
