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，只将函数更改为：
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;
}
如果有效，请对其余字段应用相同的逻辑，并删除调试消息。
