并且Javascript文件包含:

alert(alerttxt);

else
{

{
username.focus();
return false;

if (validate_required(address,"Address must be filled out!")==false)
{

很抱歉,如果我错误地列出了代码......我似乎不明白该怎么做:(
感谢您给予的任何帮助

@Matthew Wilson正确指出验证文件有404错误:
<script type="text/javascript" src="script/java/validation.js">
----------------------------------------^
确保您指定了正确的路径并且文件存在。
问题在这里:
onsubmit="return validation.js:validate_form(thisform)"
应该是:
onsubmit="return validate_form(thisform)"
答案 1 :(得分:0)
您是否已将脚本文件包含在页面中:
<script type="text/javascript" src="validation.js"></script>
。接下来从表单的onsubmit中删除validation.js:
...这是不需要的。如果它仍然不起作用,那么一些调试。在验证表单功能中粘贴警报(“表单已提交”),看它是否会触发。如果没有,你需要弄清楚原因,如果是的话,在功能树下面进一步发出警报,找出发生了什么。
答案 2 :(得分:0)
查看您提供的URL,您的脚本标记全部错误
第7行
<script type="text/javascript" src="script/java/validation.js">
应该是
<script type="text/javascript" src="script/java/validation.js"></script>
第8行
<script>
应该是
<script type="text/javascript">
并删除第50行的额外脚本标记
</script>
