借此自己也学习下,写了个小例子，你看看

<script>
function show(){
var a=[['12-22','01-19','魔蝎座'],['01-20','02-18','水瓶座'],['02-19','03-20','双鱼座'],['02-21','05-20','白羊座'],

var datePattern = /^(\d{4})-(\d{1,2})-(\d{1,2})$/;
var birthday=window.prompt('输入你的出生年月日(格式如1985-10-15)','');
try{
if(!datePattern.test(birthday)&&birthday){
alert('请输入正确的生日格式');
}
else{
var b=new Date(Date.parse(birthday.replace('-','/')));

s=RegExp.$1;

if(b>=start_date&&b<=end_date){

break;
}
}
if(i=='12'){
window.status='错误的出生日期,无法解析';

alert("格式错误"+e);
