[zz1981]

请问这个日期的正则表达式怎么写

//验证日期
function ValidateDate()
{

var reg=/^(\d{4})(\/|-)(\d{1,2})\2(\d{1,2})$/;
var arr=document.RegExpDemo.txtDate.value.match(reg)
if(arr==null)
{
window.alert("错误的时间格式,请按格式填写\n 如: 1999/10/25 或 1999-10-25");
document.RegExpDemo.txtDate.select();
document.RegExpDemo.txtDate.focus();
return;
}

var tempDate=new Date(arr[1],arr[3]-1,arr[4]);
if((tempDate.getFullYear()==arr[1]&&(tempDate.getMonth()+1)==arr[3]&&tempDate.getDate()==arr[4])==false)
{
window.alert("错误的时间格式,请按格式填写\n 如: 1999/10/25 或 1999-10-25");
document.RegExpDemo.txtDate.select();
document.RegExpDemo.txtDate.focus();
return;
}
window.alert(document.RegExpDemo.txtDate.value);
return;

}

还有个笨办法:
try
{
DateTime test=Convert.ToDateTime(yyyy-mm-dd):
}
catch
{
Response.Write("不是日期");
}
