推荐答案

在将带有表单标记的s:url标记与参数一起使用之前，可以构建URL. s:form标记使用action属性来映射动作，但是如果它们的格式正确，它也会接受URL.那就是我们现在要做的.

You can build the URL with the s:url tag with parameters before you use it with the form tag. The s:form tag uses the action attribute to map with the action but it also accept URLs if they are properly formatted. That what we will do now.

<s:url var="deleteUrl" action="delete" includeContext="false"><s:param name="doncod" value="%{#item.doncd}"/></s:url>
<s:form action="%{#deleteUrl.substring(1)}" method="POST">

另一种方法，最推荐的方法是使用hidden字段作为请求参数来保存与表单一起提交的值.

Another approach, which most recommended is to use hidden field as request parameter to hold the value submitted with the form.

<s:form action="delete" method="POST">
<s:hidden name="doncod" value="%{#item.doncd}"/>

因此，这两种方法都可以用于传递带有表单操作的参数.

So, these two methods could be used to pass a parameter with the form action.
