/*******************************
** 表单验证
使用说明:
在使用表单的页面填入如下script
<script language="JavaScript" type="text/javascript" src="../css/form.js">
</script>
<script language="JavaScript" type="text/JavaScript">
function checkForm(theForm) { //v2.0
  if (!checkNotNull(theForm.name,"姓名")) return false;
  if (!checkNumber(theForm.age,"年龄")) return false;
  ...
  return true;
}
</script>

注意:checkNumber(),checkLength()等方法并不检查是否为空

<FORM name="form1" acton="..." onSubmit="return checkForm(document.form1)">
...
<input type="submit" name="Submit" value="Submit">
</FORM>
