请问在客户端怎么处理日期数据？比如日期验证等

Question

<script language="javascript">
function check()
{
  var m=/^(\d){4}-(\d){1,2}-(\d){1,2}$/;
  s=document.all("input").value.match(m)
if (s==null)
{
  alert("日期不正确");
  return false;
}
else
{
  var d=new Date(s[1],s[2],s[3]);
  if(s[2]!=d.getMonth())
  {
     alert("日期不正确");
     return false;
  }
  if(s[3]!=d.getDate())
  {
    alert("日期不正确");
    return false;
  }
}
}
</script>
<input type="text" name="input" onBlur="check()">

Answer 1

我这里是直接调用VBScript函数做的。
<Script language="VBScript">
    Function fCheckDate(str)    
        fCheckDate = 0
        If (IsDate(str) OR str = "//") Then
            fCheckDate = 1
        Else
            fCheckDate = 0
        End If
    End Function</Script>
然后在JS中直接调用这个就可以了。
if (!fCheckDateValue(form))
{
return false;
}
