<script type="text/javascript">
function compare(beforeTime,endTime){
//beforeTime/endTime的格式2014-03-11 12:00
if(todate(endTime) <= todate(beforeTime)){
//这里作处理
}
}
function todate(str_time){
//格式2014-03-11 12:00
var dateArr = str_time.substring(0,10).split('-');
var timeArr = str_time.substring(11,16).split(':');
return new Date(parseInt(dateArr[0]),parseInt(dateArr[1]) - 1,parseInt(dateArr[2]),parseInt(timeArr[0]),parseInt(timeArr[1]));

var time_str1 = document.getElementById('timetext1').value;
var time_str2 = document.getElementById('timetext2').value;
if(time_str1 !== '' && time_str2 !== ''){
var time1 = new Date(time_str1.replace(/-/g,"/"));
var time2 = new Date(time_str2.replace(/-/g,"/"));
if(time1 === time2){
alert('=');
}
else if(time1 > time2){
alert('>');
}
else{
alert('<');
}
else{
alert('empty');
}
ps：手打的，自己试试，不行勿怪。
