我使用脚本标记包含了外部javascript文件，但验证无效。
这是我的外部javascript代码，保存为validation.js，我无法找到错误，请帮帮我。
// After form loads focus will go to first name field.
function firstfocus()
{
var fname = document.f2.fname.focus();
return true;

{
var fname = document.f2.fname;

if (fname_len == 0 || fname_len >= my || fname_len < mx)
{
alert("First Name should not be empty / length be between "+mx+" to "+my);
fname.focus();
return false;
if(fname.value.match(letters))
{
// Focus goes to next field i.e.Last Name
document.f2.lname.focus();
return true;

如果.js与html
不在同一文件夹中，则必须引用.js EDIT
function fname_validation(mx,my)
{
缺少结束括号！
答案 1 :(得分：1)
尝试将<script type="javascript/text">更改为<script type="text/javascript">
并仔细检查你的js文件的引用。另外，进行警报检查以确定它是否真正通过firstFocus（）函数。
答案 2 :(得分：1)
我更改了java脚本文件，现在我可以在表单中找到验证...
感谢您的帮助..
我在这里分享我的代码......
