<form name="form1" method="post" action="ad/BusinessAction!list.action">

//下面input框提交的action不同，用onclick跳轉，寫一個js方法

<input type="button" class="mulButton" name="Ids" id="allcheck" onclick="manySend('ad/BusinessAction!sendmany.action')" value="批量導入到成功案例"/>

<script>

//js方法如下

function manySend(href){
var form = document.form1;
form.action = href;//傳想要跳轉的路徑
form.submit();
}
