验证函数中可能存在运行时错误，例如，当表单不包含txtdistributor下拉列表时。

为了调试，仅将功能更改为：

function validateform() {
   alert("validation started");
   var oDDL = document.frm.txtdistributor;
   if (oDDL) {
      if (oDDL.value == '') {
         alert('Please input distributor');
         oDDL.focus();
      }
   } else {
      alert("form does not contain txtdistributor");
   }
   alert("validation ended");

   return false;
}

如果这样可行，则对其余字段应用相同的逻辑并删除调试消息。

asp和javascript消息警报不起作用
