在JSP页面中

	<script type="text/javascript">
			$(document).ready(function() {
	            $("#btnImport").click(function(){
	                $.jBox($("#importBox").html(), {title:"导入数据", buttons:{"关闭":true},

在body中添加隐藏域

<body>
	<div id="importBox" class="hide">
		<form id="importForm" action="${ctx}/basic/personInfo/import"
			  method="post" enctype="multipart/form-data" class="form-search"
			  style="padding-left: 20px; text-align: center;"
			  onsubmit="loading('正在导入，请稍等...');">
