Struts2剔除了Struts中对于form的应用,而actionStrus2)的action则综合了action,和actionForm的应用。但很多的应用中,都需要对输入进行验证,Struts中是将输入给表单,然后取得表单数据进行验证。虽然Struts2中取消了form的应用,这种方式还可以通过灵活地转化来继续使用。下面是两个例子,原理是相同的。因为博文8万字符限制,两个例子分开写。
例一
<SCRIPT>
function save(){
    var url="<c:out value='${cpath}'/>/publication/mydraftupdateAction.action?param=1"
      document.userForm.action=url;
   document.userForm.method="post";
   document.userForm.submit();
}  
function tosubmit(){
 
    var url="<c:out value='${cpath}'/>/publication/mydraftupdateAction.action?param=0"
    document.userForm.action=url;
   document.userForm.method="post";
   document.userForm.submit();
}
</SCRIPT>
 
<form name="userForm" method="post">
    <input type="hidden" name="publication.id" id="id" value="${publication.id}" />
<table width="95%" align=center cellspacing="1" class="contentTable">
    <tr> <td class="low" width="20%">
        稿件标题
        </td>
        <td class="lowest" width="30%">
    <input type="text" name="publication.title"   id="title"value='${publication.title}'>
        </td>
</tr>
</table>
<table width="95%" border="0" align="center" cellpadding="4"                cellspacing="1">
    <tr>
        <td align="right">
    <input name="button" type="button" class="button01"
        onmouseover="makevisible(this,0)"
            nmouseout="makevisible(this,1)" onclick="save()" value="保存"
            style="cursor: hand;">
    <input name="button" type="button" class="button01"
            onmouseover="makevisible(this,0)"
            onmouseout="makevisible(this,1)" onclick="tosubmit()" value="提交"
            style="cursor: hand;">
    <input name="button" type="button" class="button01"
            onmouseover="makevisible(this,0)"
            onmouseout="makevisible(this,1)" onclick="history.back()"
            value="返回" style="cursor: hand;">
        </td>
        </tr>
    </table>
总结:先给form命名(useform),点击"保存"触发onclick="save()"save()方法指定执行的actionrul,和将整个useform)提交submit((将整个useform)提交submit)不能少,不然会不能提交)同理 onclick="tosubmit()" value="提交")也一样
