給action增加引數pageIndex需要設定 method為post

<script type="text/javascript">
        function goPage(pageIndex){
            document.forms[0].action="search.action?pageIndex="+pageIndex;
            document.forms[0].submit();
        }
</script>

<FORM action="search.action" method="post" >

</FORM>

<a href="javascript:goPage(${requestScope.pageInfo.pageIndex-1 })">上一頁</a>
